Published: December 2022

Vanaraja female line (PD-2) chicken was evaluated for growth, production, carcass and egg quality traits utilizing the data generated from 3,737 chicks and 599 hens produced in pedigreed mating with 50 sires and 250 dams at ICAR-Directorate of Poultry Research, Hyderabad, Telangana. Fertility was 86.63% and the hatchability was 86.72% on fertile egg set and 72.53% on total egg set basis in PD-2 line. The least squares means (LSM) for six week body weight and shank length were 662.38±2.54 g and 71.48±0.12 mm, respectively. Sex had significant influence on live weight, thigh and wing proportions wherein cocks had heavier and stronger legs and wings. Abdominal fat was significantly higher in females. The egg production up to 40 and 52 weeks of age was 80.29±0.03 and 133.16±0.05 eggs, respectively. The egg mass up to 52 weeks of age was 7447.41±2.98 g in PD-2 line. The heritability was low up to 15% for egg production and 17% for egg mass, the primary trait of selection in PD-2 line. Egg mass and egg weights at different ages had positive association as larger and high number of eggs contributed more to the egg mass. The egg mass and egg production had a significant positive association in PD-2 line. The egg quality was reasonably fair with average shape index of 75.22 and Haugh unit of 79.0±0.62. The albumen, yolk and shell weights were 30.20±0.14, 15.8±0.09, 0.40±0.02 g, respectively. The proportion of heritability and the magnitude of association between the important traits provide requisite information for implementing the breeding program for improvement of egg production in PD-2 line.
Effect of summer stress and supplementation of vitamin E and selenium on heat shock protein 70 and anti-oxidant status in Hallikar cattle
Authors: KALMATH G P , SWAMY M NARAYANA
Published: December 2022

Present study was conducted to ascertain the influence of supplementation of vitamin E and selenium on heat shock protein 70 (HSP70) and anti-oxidant status in Hallikar cattle during different seasons. Female Hallikar cattle (12) aged 4 to 6 years selected from Ramanagara, Karnataka, India, were divided into control and supplemented groups with 6 animals in each group. Selected animals were exposed to environmental stressors during 3 different seasons (winter, summer and rainy) by allowing them for free grazing. Animals of supplemented group received oral supplementation of vitamin E and selenium, and control group animals did not receive any supplementation. Blood samples collected from each animal at monthly interval were utilized to determine plasma levels of HSP70 and erythrocyte activities of catalase, superoxide dismutase and glutathione peroxidase in hemolysates (10%). Present study showed significant increase in plasma HSP70 levels during summer compared to winter in control and supplemented groups. However, plasma HSP70 levels did not vary significantly between control and supplemented group during different seasons. Activities of catalase, superoxide dismutase and glutathione peroxidase enzymes were also significantly higher during summer compared to other seasons in both control and supplemented group. However, activities of these enzymes reduced significantly in supplemented group compared to control group animals. From the study, it was concluded that significantly lowered antioxidant enzyme activities in supplemented group indicate beneficial effects of supplementation of vitamin E and selenium during summer.

Published: December 2022

Enterolobium cyclocarpum (Ec) is a native legume that grows from southern Mexico to South America; its seeds are traditionally used for feeding ruminants. The objective of this study was to evaluate the addition of Ec pods in diets of hair lambs and their effect on the productive variables, ruminal fermentation and in vitro production of methane (CH4) and carbon dioxide. Thirty male lambs fed diets containing 0% (Ec0), 20% (Ec20) and 40% (Ec40) based on dry matter were evaluated. The addition of Ec40 in the integral diet of the lambs did not affect the growth performance. The pH of the ruminal fluid did not show differences between the treatments. The addition of Ec40 increased propionate and decreased acetate. Protozoa decreased in 47 and 59% with Ec20 and Ec40, respectively; while the population of cellulolytic bacteria decreased with Ec40. In vitro degradability of dry matter was lower in 8.8% with the inclusion of Ec40 in diets. The novelty of the study was that Ec40 diet decreased the ruminal methane production.

Published: December 2022

This paper examines the emerging trends and growth of livestock sector at disaggregate level in Uttar Pradesh (UP) from 2004–05 to 2015–16. The share of crop sector in GSDP had declined sharply while livestock sector gained a significant share due to consistent higher growth in agricultural sector of the state. The regional level result indicated that Western UP outperformed Eastern, Central and Bundelkhand regions in that order with high disparities across the regions in case of livestock sector as well as rural infrastructure. Moreover, Fixed Effects model attested a positive and significant relationship between value of output by livestock and rural infrastructure index. It suggested that adequate development avenues via rural infrastructure, extension services, value chain development and research investments can boost the growth of livestock sector and mainstreaming the livestock development. Also, the state can utilize the opportunities by promoting livestock as a dominant approach towards livelihood diversification as adopted by other states as well. This will not only take care of the already overstressed agriculture sector but will also be instrumental in attaining the objective of doubling farmers’ income.

Blood biochemical profile plays a pivotal role in assessing health status of animals. The present study was conducted to evaluate haematological and biochemical parameters, trace element and electrolyte concentration, oxidant and antioxidant status in local cattle (Zobawng) of Mizoram. The values recorded for Hb (12.61±0.40 g/dL), RBC (9.10±0.50 106/μL), WBC (11.52+1.13 103/μL), PCV (43.36±0.99%), total protein (8.30±0.17 g/dL), globulin, BUN (10.68±0.68 mg/dL) were on higher side than the exotic cattle breeds. Creatinine (1.96±0.10 mg/dL) and GGT (19.22+1.29 U/L) were also towards upper limit. Calcium (9.78+0.13 mmol/ L), magnesium (2.43+0.07 mmol/L) and inorganic phosphorus (6.76+0.27 mmol/L) values were higher than the exotic breeds and also higher than the Indian Zebu cattle. Total antioxidant was higher and the oxidative stress index was lower as compared to the crossbred or exotic cattle. This study provides first insight into the blood biochemistry of these indigenous cattle indicating its higher disease resistance and will be useful for its better management.

Published: December 2022

A study was undertaken to determine the components of genetic variance and gene action effects in snowball cauliflower (Brassica oleracea var. botrytis L.) lines through line × tester analysis involving 5 Ogura CMS lines and 7 male fertile testers. The mean squares due to lines and testers were significant for most of the characters under study, except for gross plant weight, polar diameter, equatorial diameter, curd weight, curd yield and harvest index and for line × tester, it was significant for leaf length, leaf width, number of leaves per plant, plant height, days to 50% curd initiation and days to 50% curd maturity. Pre-dominance of dominance component of variance was observed for leaf length, number of leaves per plant, plant height, days to 50% curd initiation, marketable curd weight and marketable curd yield. The traits studied had narrow differences among GCV, PCV and broad sense heritability values, suggesting low effect of environment on the expression of phenotype for most of vegetative traits. The variance due to general (σ2gca) and specific combining abilities (σ2sca) were highly significant indicating the importance of both additive (σ2A) as well as non-additive (σ2D) type of gene actions. However, the ratios of σ2gca/ σ2sca (<1) and σ2A/σ2D (<1) revealed the preponderance of non-additive variance for the inheritance of traits studied except for days to 50% curd initiation and harvest index. The results of the experiment suggest the possibility of improvement of these traits through recurrent selection and hybridisation.

Authors: BEHERA SANJIB KUMAR , MATHUR RAVI KUMAR , SURESH KANCHERLA
Published: December 2022

Leaf samples were collected from 17th frond of 157 palms comprising 52 accessions of teneras and Cameroon, Guinea Biassau, Zambian and Tanzanian duras available in the field gene bank of ICAR-Indian Institute of Oil Palm Research, Pedavegi, Andhra Pradesh, to assess the variation in leaf nutrient concentrations of oil palm (Elaeis guineensis Jacq.) germplasm. Collected leaf samples were processed and analysed for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S) and boron (B) concentration. Leaf nutrient concentrations varied widely across the germplasm. Cameroon (0. 88%), Zambian (0. 91%) and Tanzanian (0. 98%) duras recorded higher leaf K concentration compared to Guinea Bissau duras and teneras. The teneras like 118×57, 134×57, 29×155, 139×155 and D×N (Deli×Nigeria) recorded higher leaf S concentration. Among the Zambian duras, ZS-1, ZS-3 and ZS-5 accessions recorded higher leaf K concentration, whereas ZS-2, ZS-3, ZS-6 and ZS-8 accessions had higher leaf Ca concentration. These findings could play a vital role in identification and development of nutrient efficient oil palm germplasm.

About 85% farmers of the north eastern hill region (NEHR) of India are small and marginal. Hence, there is need for establishing package of practices in an integrated manner to enhance on-farm resource recycling, employment, income and sustain soil health. An integrated organic farming system (IOFS) model (0. 43 ha) was assessed during 2005- 2017 at ICAR Research Complex for NEH Region, Umiam, Meghalaya (960 m ASL) with diversified farming components like field crops, horticultural crops, livestock (one cow + calf) along with perennial fodder crops, central water harvesting pond for composite fish culture and as a source for irrigation during lean season and provision for nutrient recycling. The productivity and income from the on farm IOFS model was compared with the ruling farmers practice-I (Monocropping, i.e. rice-fallow system) and farmers practice-II (cultivating about 30% farm area for second crop like vegetables after rice). The average results indicated that the rice equivalent yield (REY) from the IOFS model was 19. 8 t/ha as against 4 t/ha and 6.72 t/ha from the farmers practice-I and II, respectively. The enhancement in net income due to IOFS was 355 and 191% relative to farmers practice -I and II, respectively. The IOFS model could meet 92, 82 and 96% (N, P2O5 and K2O) of its nutrient demand within the system. The IOFS model was also replicated in farmersâ€™ field through participatory approach in three villages covering about 110 ha area and 317 households during 2013 to 2017. After 4 years, on an average farmers productivity of various crops (tomato, potato, chili, carrot, French bean, ginger and turmeric) enhanced by 15 to 45% and annual income enhanced by about ` 15500 per house hold. Thus, IOFS could be a viable option for organic food production and sustainable agricultural development in the hill ecosystem of north east India.

Published: December 2022

CropSyst is a daily time step crop growth simulation model that can be used to study the effect of cropping systems management on crop productivity and environment. A total five years experimental field observations (2009-10 to 2013-14) comprising four sowing dates, viz. November 1, 15, 30 and Dec 15 for wheat-fallow crop rotations were used to simulate the growth, phenology and yield for wheat cultivar GW 322 at Anand (Gujarat). Among the five years observations, initial two years observations (2009-10 and 2010-11) were used for model parameterization and remaining yearâ€™s observations (2011-12 to 2013-14) were used for model performance evaluation. The results indicated that the model was able to predict the wheat phenology precisely in terms of mean bias error (MBE) and root mean square error (RMSE) which was less than 6 days for all the phenological stages except maturity date on Dec 15 sowing. Nov 15 sowing has resulted in maximum grain and biological yield and found to be optimum date for sowing followed by Nov 30 for this region while Dec 15 resulted in highest yield reduction. It was also observed that CropSystmodel was efficient in simulation of yield and biomass of wheat crop during various years of observations. The model has efficiently predicted grain and biological yield with Â±10% of model error for wheat crop. However, it failed to predict the leaf area index (LAI) precisely. It may also be concluded that the model error were less for early and normal sown crops but increased with the delay in sowing.

A field experiment was carried out to study the effect of zinc and iron on growth, yield and quality of chrysanthemum (Chrysanthemum morifolium Ramat. ) cv. Mayur 5 during 2016 and 2017. The experiment was laid out in randomized block design with three replications comprising nine levels of micronutrients, i. e. control (T1), ZnSO4 @ 0. 1% (T2), ZnSO4 @ 0. 2% (T3), ZnSO4 @ 0. 5% (T4), FeSO4 @ 0. 2% (T5), FeSO4 @ 0. 5% (T6), FeSO4 @ 0. 8% (T7), FeSO4 + ZnSO4 @ 0. 5% each (T8) and FeSO4 + ZnSO4 @ 0. 7% each (T9). Combined foliar spray of FeSO4 + ZnSO4@ 0. 5% recorded best results for number of branches per plant (37. 00), minimum days for flower opening (94. 67), petal length (2. 17 cm), petal width (0. 63cm), flower bud diameter (1. 339 cm), flower longevity (28. 00 days), single flower weight (1. 27g), plant dry weight (98. 33 g), number of flowers per plant (218. 33), flower yield per plant (218. 33g) and flower yield/m2 (2988. 62g). Maximum flower diameter and chlorophyll content (SPAD reading) was also recorded with individual spray of FeSO4 @ 0. 5% (T6). Among the treatment, ZnSO4 + FeSO4 @ 0. 5% (T8) gave best results for flower production and yield for chrysanthemum under open field conditions.

Authors: RIALCH INDU , SHARMA JAI DEV
Published: December 2022

The present investigation was undertaken in F1 population of 36 crosses, obtained by crossing 18 inbred lines of soybean with two diverse testers in line Ã— tester mating design during kharif 2012. All the parental lines and their F1 hybrids were evaluated in randomized complete block design at the Experimental Farm of Department of Crop Improvement, CSK HPKV, Palampur (HP ) during kharif 2013. The aim of this study was to identify suitable parents and hybrids for yield and its contributing traits. Experimental results revealed significant differences for lines, testers and line Ã— tester for majority of the traits studied. Lines Bragg, Shivalik and P9-2-2 were found to be good general combiners for most of the traits. The cross combinations, Bragg Ã— Hara Soya, DS-1213 Ã— Hara Soya, H-330 Ã— Hara Soya, PK-472 Ã— Him Soya and H-330 Ã— Him soya showed high per se performance and SCA effects for seed yield per plant and were rated as potential crosses for further improvement. Further, non-additive gene action (ÏƒD2) played a major role in the manifestation of almost all the traits which suggested the use of breeding approaches such as single seed descent method, reciprocal recurrent selection with one or two intermatings and diallel selective mating for the improvement of seed yield and related traits. Selection of parents based on their combining ability is an effective approach in hybrid breeding programme.

Published: December 2022

Plant secondary metabolites exhibit a wide range of biological activity and may act as feeding and oviposition deterrents, repellents, fumigants, and behavior modifiers. Fruits and tubers of Momordica cymbalaria Hook (Fenzl.) possess anti-ovulatory and abortifacient properties that could be exploited in the management of insect pests. Hence, the feeding deterrent activity of M. cymbalaria leaf, peel (fruit skin), seed and tuber solvent extract against Spodoptera litura Fabr. was studied. Different concentrations of acetone extract of leaf from 0.3% to 0.8%, performed better in deterring S. litura larval feeding. Peel acetone extract showed a strong feeding deterrence (94.83% leaf area protection over the absolute control) at 0.9% concentration followed by medium deterrence at 0.8, 0.7, and 0.6% concentrations (85.62, 77.90, and 67.08 % protection respectively). The hexane seed extract was comparatively oilier and had a distinct rancid smell noticeable in the higher concentrations (0.8, 0.9, and 1%). Tubers did not exhibit any significant leaf area protection below 0.2% concentration. However, 1% tuber acetone extract showed 99.36 percent protection. The effective concentrations of leaf acetone extract for 50 and 95% deterrence were 0.27and 0.84 percent respectively. The effective concentrations of other plant parts were ranked as follows; Seeds>Peels>Tubers.

Algler hayatın her alanında özellikle endüstride sıkça kullanılan bir canlı grubudur. Çok farklı hücresel şekilleri vardır ve farklı habitatlarda ve yüzeylerde üreyebilirler. Doğada kolaylıkla kendiliğinden çoğalabilen algler, laboratuvar koşullarında çok steril ve dikkatli çalışılmanın sonucunda saf kültür olarak çoğalabilirler. Günümüzde biyoteknoloji alanında; biyodizel üretiminde, yenilebilir biyoplasik yapımında, balık yemi ve besin olarak, mikrobiyal gübre ve kozmetikler gibi daha pekçok çeşitli çalışmalarda kullanılan algler için farklı üretim teknikleri geliştirilmiştir. Bu üretim teknikleri yüksek maliyetlidir ve ekonomik sebeplerle istenilen miktarlarda çoğaltılamamaktadır, bilimsel çalışmalar sekteye uğramaktadır ve okullarda birçok öğrenci projesi yürütülememektedir. Özellikle ortaöğretim okullarında yapılacak bilimsel çalışmalar için alg üretmek bu nedenle sorun olabilmektedir. Buna çözüm olarak evsel bitkisel atıklar kullanılarak hazırlanacak bir alg besi ortamı hem daha ucuz hem de kolay ulaşılabilir olacaktır. Bu nedenle özellikle bitkisel atıklardan salatalık, portakal ve benzeri sebze ve meyvelerin atıkları kullanılarak alg üretimi gerçekleştirilmiştir. Yapılan çalışmalar göstermiştir ki; %20 oranında portakal atığı, %5 ve %10 oranında yumurta kabuğu özütü içeren ortamlar BG-11 besi ortamı yerine alternatif olarak kullanılabilecek besi ortamlarıdır.

El Nuevo Teatro en Colombia
Authors: Grajales Acevedo Carolina
Published: December 2022

El nuevo teatro en colombia como acontecimiento histórico trae consigo una revolución de pensamientos, nuevas formas de hacer teatro, en las que se investiga cada situación, acción, personaje, en el contexto, develando lo que sucede en el hecho actual. Un medio que muestra las inconformidades y nos encamina a una identificación, el arte escénico como posibilitador de un cambio social, que comunica y transforma pensamientos a través de su representación, su fin es la investigación-creación a partir de la metodología de creación colectiva que hace visible la historia y memoria de un país.

Ha realizado exposiciones en Bogotá, en Tokio (entre ellas un solo exhibition) y la última en 2019 en una galería bajo el marco de Art Basel en Miami.

El proyecto que vengo realizando se propone darle continuidad a personajes e historias que vienen particularmente del cine, pienso que las historias de estos personajes no tienen que acabar cuando aparece un letrero que dice “FIN” en la gran pantalla. Con la información que tengo de ellos les doy continuidad, creo conversaciones con personajes y contextos que aparentemente no tienen relación alguna. El último proyecto, por ejemplo, se trata de unas Scream Queens, personajes femeninos vulnerables que desde hace muchos años han sido atacados, asustados, asesinados por diferentes monstruos, se trata de crear un mundo ideal para ellas, entonces ya no tenemos que oír sus gritos de terror y miedo, ahora estas chicas gritan por otras razones, alegría, placer, adrenalina y otras emociones.

Pengintegrasian Kedinamisan Pasar Dalam Estimasi Nilai Pasar Properti Menggunakan Pendekatan Pendapatan Pada Masa Pandemi Covid-19
Authors: Agung Prasetyo Kristian
Published: December 2022

Faktor kedinamisan pasar selalu menjadi pertimbangan penilai dalam melakukan estimasi nilai properti. Di sisi lain, teknik penilaian properti yang banyak digunakan selama ini tidak banyak memasukkan unsur ini di dalam prosedur penilaian yang ada. Ini misalnya bisa dilihat pada ketidakpastian tingkat kapitalisasi atau penghasilan bersih yang dapat diperoleh dari properti yang sedang dinilai. Alhasil nilai yang diestimasikan pun sebenarnya masih belum mengandung unsur kedinamisan pasar properti ini. Padahal nilai properti itu sebenarnya adalah sekedar pendapat. Oleh karenanya untuk properti yang sama akan selalu didapat berbagai kemungkinan nilai jika dinilai oleh penilai yang berlainan karena adanya perbedaan data atau kemampuan penilai. Di sisi lain, estimasi nilai properti sebagai hasil proses penilaian disajikan dalam bentuk angka tunggal di dalam laporan penilaian. Ini tentunya bertentangan dengan filosofi nilai yang merupakan manifestasi atas pendapat penilai. Paper ini ditujukan untuk memberikan ilustrasi tentang bagaimana kedinamisan pasar bisa dianalisis dan disajikan dalam laporan penilaian properti dengan menggunakan pendekatan berbasis probabilitas.
Fulminant Hepatic Failure in a SARS-CoV-2 Positive Pediatric Patient: A Case Report
Authors: Blasurca Jerrymae
Published: December 2022

Respiratory symptoms are the most common manifestation of COVID-19 across all age groups and it is most often associated with radiographical findings consistent with pneumonia.2 A recent systematic review estimated that 16% of children with SARS-CoV-2 infection are asymptomatic,3 or others may present with seizures, gastrointestinal bleeding or jaundice. This reports a 2-year old boy with no known co-morbidity who had a 2-week history of abdominal pain and jaundice then had a rapidly progressive course of neurological deterioration and eventual demise. He had markedly elevated liver enzymes and deranged bleeding parameters with elevated ammonia and ferritin levels. Hepatitis B and hepatitis A titers were non-reactive. He was managed as a case of hepatic encephalopathy secondary to cholestatic jaundice. His chest x-ray was normal but his SARS-CoV-2 RT PCR result was positive with a low cycle threshold. Locally, this is the first reported case of SARS-CoV-2 RT-PCR positive pediatric patient presenting as fulminant hepatic failure with no associated respiratory manifestations. Clinicians should be mindful that such presentation, however uncommon, is possible and a high index of suspicion should be maintained.
"A Rapid Review on the sensitivity of SARS-CoV-2 RT-PCR done on different clinical specimens "
Authors: Sembrano Denise
Published: December 2022

Background: RT-PCR using respiratory tract specimens, most commonly nasopharyngeal swab (NPS), has been used to confirm the diagnosis of COVID-19. NPS is a relatively invasive procedure that causes patient discomfort and risks viral transmission. Other specimens are therefore being investigated for the detection of SARS-CoV-2 RNA. Objective: To determine the sensitivity of non-respiratory tract specimens in detecting SARS-CoV-2 RNA in patients with COVID-19. Methodology: This review summarized the results of eight studies obtained from a literature search done in May 2020 in PubMed MEDLINE, Cochrane Library and MedRxiv. Two independent investigators reviewed and appraised the studies that were included, and pooled estimates of sensitivity for each specimen were determined using Stata’s Metaprop function. Results: The sensitivity in detecting SARS-CoV-2 RNA in non-respiratory tract specimens of diagnosed COVID-19 patients are as follows: Saliva 77% (95% CI 71-83%), stool/rectal swab/anal swab 22% (95% CI 22-37%), blood/serum/plasma 2% (95% CI 1-3%), and urine 22% (95% CI 18-25%). Conclusion: SARS-CoV-2 RNA is detected in saliva, stool/rectal swab/anal swab, blood/serum/plasma and urine. Among these, saliva has the highest estimated sensitivity. However, more studies are needed to correct the heterogeneity brought about by factors such as timing of specimen collection, disease severity and treatment.
