Abstract
KUB2 KK chicken is an improved KUB1 chicken, the improved local chicken created by the Indonesian Research Institute for Animal Production (IRIAP). Carcass percentage is an important indicator to evaluate the productivity of the slaughtered chicken. The objective of this research was to evaluate the carcass percentage of male KUB2 KK chicken on different body weights. 94 heads of ten weeks old male KUB2 KK chicken were used and it was divided into six bodyweight groups (G1: 700 to 799 g, G2: 800 to 899 g, G3: 900 to 999 g, G4: 1,000 to 1,099 g, G5: 1,100 to 1,199 g and G6: 1,200 to 1,299 g). Resulted data were analyzed using one-way ANOVA. The results showed carcass percentage of G1, G2, G3, G4, G5 and G6 were 61.12 %, 61.62 %, 62.50 %, 63.47 %, 63.72 % and 64.10 %, respectively. The group of body weight resulted significantly different on carcass percentage. Carcass percentage increased with increasing body weight. Thighs were the biggest part of the carcass. It was followed by breast, back, and wings. Abdominal fat had a tendency to increase by an increasing of body weight.

Abstract
Efforts to conserve local cattle are important in order to get potential beef-producing cattle. A local cattle from Sragen District—Central Java, commonly referred to Sasra cattle, is one of the potential local cattle that will be developed. This study is intended to identify the characteristics of Sasra cattle, as part of the initial development steps. In 2017, a series of Focus Group Discussion was held by inviting historical actors, leaders, breeders, inseminators, the Sragen Regency Livestock and Fisheries Service officers, and Lembang’s Artificial Insemination Center to obtain historical data, characteristics, and farmer community responses related to the Sasra cattle. Body measurements (i.e. chest circumference, body length, and shoulder height) were taken in order to see the cattle performance. Genetical reviews of the molecular aspects have also been carried out. Results of the study showed that based on the history, Sasra cattle were a descent from the hibridization of Aberdeen Angus, American Brahman, and Ongole grade cattle breeds. Based on its phenotype, Sasra cattle could be characterized by the different head to body shape and color if compared to their ancestries, but at a glance, the body shape and color are close to the Angus cattle. There were 10 unique characteristics of Sasra cattle. The quantitative measurement of Sasra cattle is greater compared to that in other local cattle in Indonesia. Molecular evidence show that Sasra cattle have high similarity level to Bos indicus, than to Bos taurus and also confirms that Sasra cattle might have ancestry from Bos javanicus.

Abstract
The objective of this research was to find the basic data on genetic diversity of DNA D-Loop on Gayo and Toraya buffalo breed and its association with 6 local buffalo (Aceh, Sumut, Riau, Banten, Jateng, NTB, Sulsel). To the best of our knowledge this is the first published data on the complete mitochondrial D-Loop sequence of Gayo and Toraya buffalo. There were 83 samples of DNA which had been sequence; i.e. 45 from Gayo, 5 from Simeulue, 3 from Aceh Besar, Sumut and Riau, 4 from Banten, Jateng, NTB and Sulsel, 8 from Toraya. Results show that Toraya buffalo have a specific haplotype, while gayo buffalo have a closer relationship to Sumut buffalo. The total nucleotide sequenced of Gayo and Toraya buffalo and 6 local buffalo was 317 bp. The genetic distance ranges among Gayo buffalo, Riau, Jateng, Sulsel, NTB (0.010), Gayo buffalo-Sumut buffalo (0.016), and Gayo buffalo-Toraya buffalo (0.023). D-Loop mtDNA analyses showed that most of Gayo buffalo form a haplotype together with six other local buffalo populations, while the Toraya buffalo (striped buffalo) population forms one haplotype that is separate from the entire local Indonesian buffalo population. These finding could be assumed that the Toraya buffalo (striped buffalo) originating from Enrekang forms a specific haplotype which identifies that the Toraya buffalo (striped buffalo) originating from Enrekang is animal genetic resource of native livestock that must be preserved.

Abstract
The purpose of this study was to evaluate the scrotum circumference and testosterone levels at various ages of the Gayo buffalo. This study involved 10 Gayo buffalo with four different age groups I: (1.0–2.0), II (2.1–3.0), III (3.1–4.0), IV (4.1–5.0). Blood serum sampling, measurement of scrotal circumference, and age were carried out in Central Aceh regency. The analysis of blood serum testosterone levels was carried out in the physiology laboratory of the Faculty of Veterinary Medicine at Universitas Syiah Kuala. Data on testosterone levels, scrotal circumference, and age were analyzed for variance and continued with Duncan’s Multiple Range Test for data with significant differences. Simple regression analysis was used to determine the relationship between scrotal circumference, age, and testosterone levels. The results of the analysis in the age group and the concentration of the hormone testosterone showed significant differences (P <0.05). The age group of 3.1 to 4.0 years was significantly different from the age group of 1.0–2.0, 2.1–3.0 years, and 4.1–5.0 years. The results of the analysis on the scrotal circumference and testosterone concentration showed no significant difference (P>0.05) in various age groups. There was a significant relationship (P<0.05) between the concentration of the testosterone hormone with age and scrotal circumference, with a regression equation Y= 1.009-0.076X1+0.002X2, with a correlation coefficient (r) of 1 and a coefficient of determination (R2) of 1. These results indicated that scrotal circumference and age greatly influenced the concentration of the testosterone hormone of Gayo buffalo. The conclusion was that age affected the scrotal circumference, but it did not affect the concentration of the testosterone hormone. Gayo buffalo aged 3.1–4.0 and 4.1–5.0 years had a stronger correlation than Gayo buffalo aged 1.0–2.0 and 2.1–3.0 years to scrotal circumference and testosterone concentration.

Abstract
Madura cattle is one of the local cattle in Indonesia that have the various phenotype, especially in growth. The objective of this study was to identify SNP of Somatostatin gene on Madura cattle at Village Breeding Centre (VBC), Madura Island. A total of 66 Madura cattle was used in this study and 34 Ongole Grade cattle as a population reference. Blood samples were collected at VBC Waru, Pamekasan Regency. A potential SNP in exon 1 was analyzed using Polymerase Chain Reaction-Restricted Fragment Length Polymorphism (PCR-RFLP). A restriction enzyme of BsrI was used to identify the SNP. The results showed that a 464 bp of DNA fragment was successfully amplified and an SNP c.20G>A was identified in this study. This SNP was categorized as a missense mutation with the change of amino acid from serine (AGT) to asparagine (AAT). An A allele was only found on Madura cattle. The frequency of A allele was 1.00 in this population and was defined as monomorphic or monoallelic. This result probably indicated that Madura cattle at VBC Waru were selected in this locus.

Abstract
To reduce the feed cost in raising chickens it is necessary to find alternative feed sources. The feed ingredients must have relatively low prices, do not compete with human needs, and have abundant availability on location. The purpose of this study was to determine the performance of KUB chicken production with feed containing Lamtoro (Leucaena leucocephala) leaf flour (LLF). The study was conducted using 300 chickens aged 4 weeks, unsexed, which were allotted to 4 treatments, each with 5 replicates and 15 birds per replicate in a Completely Randomized Design. The treatments were in the form of a) T0: 0% LLF; b) T1: 3% LLF; c) T2: 5% LLF and d) T3: 7% LLF. The LLF was mixed with a basal feed in a mixture of concentrate, corn and bran. The study lasted for 6 weeks, i.e. until the chicken was 10 weeks old, with observations including daily weight gain (DWG), feed consumption, feed conversion ratio (FCR), and income over feed cost (IOFC). The results showed that the best performance of KUB chicken production was by the addition of 5% LLF in the feed, as it could increase the DWG value, reduce the FCR value and increase the IOFC value.

Abstract
The demand for high quality and healthy meat has been continuously increasing both in national and international markets. The objective of this study was to investigate the effect of gambir (Uncaria gambir) leaf extract as a feed additive on cholesterol content and consumer preference of goat meat. Eighteen Boerka goats aged 10-11 months with an average initial body weight of 20.5±2.79 kg were randomly distributed to three dietary treatments, namely: GE0 (fed basal diet without gambir extract supplementation, GE100 (gambir extract supplementation at levels of 100 mg/kg body weight, and GE200 (gambir extract supplementation at levels of 200 mg/kg body weight. Meat cholesterol content was measured using the Liebermann Buchard method. The meat quality preference was measured using the hedonic scale of the organoleptic method from 16 panelists. Results showed that addition of gambir leaf at 200 mg/kg BW resulted meat cholesterol content of 14.9%, numerically lower than that of control. The meat color, flavour, juiciness and taste were similar among the dietary treatments. The meat was classified as mild juicy meat with a bright red color and well accepted flavour and taste. Based on the hedonic scale, the tenderness level of goat meat fed with 200 mg/kg BW of gambir leaf extract increased from mild tender (in the control treatment) to tender. In conclusion, gambir leaf extract has the potential to reduce cholesterol content and increase meat tenderness without having a negative effect on consumers preference regarding the color, flavour, juiciness and taste of the goat meat.

Published: June 2021

Abstract
The effects of palm oil and water temperature on preparation of bioactive edible film (BEF) in total mixed ration (TMR) pellets were investigated, with highlight on hardness and microbial composition. The research followed a completely randomized design (CRD) with factorial of 4 × 4 with 3 replications. The first factor was crude palm oil (M) with levels of 0%, 1.5%, 3%, 4.5%, while the second factor was water temperature (T) as a solvent for tapioca flour, namely 30 °C, 35°C, 40°C, and 45°C. The results showed that palm oil concentration and water temperature had a significant effect (P <0.05) and showed an interaction between the two factors on the hardness of BEF TMR pellets. Lactic acid bacteria (LAB) and fungi population decreased with the addition of palm oil content and increasing of water temperature. Coliform was not detected in all palm oil and temperature treatments. It could be concluded there was an interaction between addition of palm oil and water temperature to the hardness of BEF TMR pellets, with the best combination produced by 3% palm oil and 35°C water temperature. The population profile of LAB and fungi at treatment of 3% palm oil and 30°C produced the most satisfied pellet which also meets Indonesia National Standard (SNI) for ruminant feed.

Abstract
This study aims to determine the effect of substitution of soybean meal with Indigofera (Indigofera zollingeriana) leaf flour (ILF) and turmeric (Curcuma longa) flour on the carcass weight of the native chickens. A total of 80 8-weeks-old Indonesian native chicken were fed 4 types of a ration containing ILF and turmeric flour to substitute soybean meal based on the completely randomized design with 5 replication. The formulated ration consisted of basal feed (R0), 10% of ILF and 2.5% turmeric flour (R1), 15% ILF and 2.5% turmeric flour (R2), 20% ILF and 2.5% turmeric flour (R3), respectively. At the end of the experiment, 2 chicken sample from each group were selected and slaughtered for further carcass characteristics measurement. Partial carcass percentages of the chest, thigh, and back were not affected by the substitution of soybean meal with ILF and turmeric flour in the ration, however, wing percentage was significantly higher in the group of chicken fed 15% of ILF and 2.5% turmeric flour (R2) compared to other groups.
The functions of Cinnamomum burmannii as an antioxidant feed additive for broiler chickens: A review
Authors: Nurhasmiati  , Purwanti S 
Published: June 2021

Abstract
Broiler chickens are livestock poultry that produces meat and are mostly maintained by the community. The increasing demand for broilers causes breeders to try to accelerate and improve the performance of broilers. The increase in broiler chickens must also pay attention to immunity because of the changing seasons which usually causes disease and can cause death in chickens. The addition of feed additives as a supplement for broiler chickens can increase immunity, one example is cinnamon because it contains antioxidants. Antioxidants are compounds that can counteract or reduce the negative effects of free radicals. We can find natural antioxidants in cinnamon (Cinnamomum burmannii). Feed additives have now been limited by the government in the feeding additive containing chemicals so the need for innovation of feed additives made from herbal materials that do not harm chickens and humans who consume them. This cinnamon study has a real influence on broiler chickens as a feed additive in their influence on antioxidants and chicken cholesterol. Broiler chicken antioxidants have a noticeable effect on femoral musculus in a combination of 100% kombucha tea with 5% cinnamon with ratio (1:1) (49.7%) and a combination of 100% kombucha tea with 5% cinnamon with ratio (1:3) (69.6%) in musculus pectoralis major. The content of cinnamon phytochemical compounds from the phenylpropanoids class in the form of cinnamic acid (Cinnamaldehyde compound) which belongs to the phenylpropanoid group is a derivative of phenol compounds, where the phenol compound also plays an important role in antioxidant activity. High antioxidants can have a positive effect on broiler chickens that are easily exposed to disease because it has the effect of preventing the formation of free radicals, eliminating radicals before damage appears, repairing oxidative damage, eliminating damaged molecules in broiler chicken cells. While on cholesterol parameters we know that broiler chicken meat has a high cholesterol content of 98.82-104.31 mg/100 g. The results of the study obtained a combination of 100% kombucha tea with 5% cinnamon with ratio (3:1) results of 3.71% femoral musculus and a combination of 100% kombucha tea with 5% cinnamon with ratio (1:1) (4.04%) musculus pectoralis major. The cinnamon content of saponins and tannins managed to lower the cholesterol content in broiler chicken meat.
