title: Utilization of guava extract as additive antioxidant in diets of Japanese quail breeders (Coturnix japonica)

description: SUMMARY The aim of this study was to evaluate the guava extract as an antioxidant additive in diets of Japanese quail breeders on the performance and egg’s quality. The experiment was conducted at University Federal of Goias. A total of 384 Japanese quail breeders were used, distributed in four treatments, with six replicates, with a total of 12 females and four males in each replicate. The treatments were performed with four levels of guava extract in the diets (0.0%, 0.3%, 0.6% and 0.9%). The guava extract contained the ellagic acid, considered the guava antioxidant active principle. The diets were isonutritive. Feed and water were offered ad libitum. The experimental period was 84 days. Egg production, feed intake, feed conversion ratio, egg mass, body weight variation and egg quality were evaluated. The results were submitted to analysis of variance and regression analysis. The adopted probability was 5%. Egg production, feed intake, feed conversion ratio and egg mass were not influenced by the use of guava extract. The yolk and albumen height, the Haugh Unit and the yolk and albumen index decreased linearly as the levels of guava extract in the diet increased. The diameter of the albumen was higher with the use of 0.48% of guava extract in the diet. The yolk color was affected by the guava extract, presenting a darker color with 0.50% of guava extract in the diet. It was concluded that the guava extract used as an antioxidant additive does not improve the performance and egg quality of Japanese quails.

title: Ingestive behavior, ruminal and blood kinetics in lambs fed cow cheese whey

description: ABSTRACT The objective of this study was to evaluate the inclusion of cow cheese whey (CCW) in the diet for lambs on the ingestive behavior, ruminal and blood parameters. Twenty crossbred, male, non-castrated lambs with 25 kg body weight were assigned to four treatments: control diet (composed of corn, soybean meal and native pasture silage) and test diets (control diet + inclusion of CCW in increasing levels of 1.6, 2.7 and 4.0% in DM), in a completely randomized design with four treatments and five replications. Means were compared by Tukey’s test, and the strength of association between variables was tested by Pearson’s correlation. Regression analysis was also performed for data from the collection of ruminal fluid and blood. Behavioral assessments were made at a 24-hour interval in measurements taken every five minutes. The inclusion of CCW in the diet did not impair ruminal pH, but promoted a decrease in rumination and feeding times, also causing a lower number of cuds and a lower number of cud chews. The lowest concentration of ammonia nitrogen and total protein were found in lambs receiving the diet with 4% CCW. However, these values were within the range recommended for microbial growth. CCW is a potential protein alternative in lambs feed as it does not interfere with nutrient intake, ruminal and blood parameters, and favors a positive nitrogen balance.

title: Pruning as a strategy to improve the nutritional value of the aerial parts of industry- purpose cassava clones

description: ABSTRACT The present study aimed to assess the influence of pruning on the starch yield and nutritional value of the aerial parts of industry- purpose cassava clones adapted to the Cerrado region of Central Brazil. Four elite clones were submitted to either total shoot pruning or no pruning at 12 months after planting, in a randomized complete block design with three replications. Plants were evaluated eighteen months after planting. Clone 330/09 presented the highest root yield with and without pruning, and also higher starch yield, green and dry mass yields, and crude protein yield of aerial parts without pruning. In plants that were pruned, clones 117/09 and 359/09 stood out, with higher yields of the crude protein content of the aerial part and a higher in vitro digestibility of the dry matter. These clones are therefore an option when using the aerial parts of cassava in animal feed. Total pruning at 12 months of age significantly increased the crude protein content and in vitro digestibility of the dry matter of the aerial parts, improving its nutritional value. Pruning did, however, reduce the starch yield of the roots and the total yields of the roots and aerial parts.

title: Occurrence of Babesia bigemina and Anaplasma marginale in clinically affected cattle in western Santa Catarina, Brazil

description: ABSTRACT The objective of this study was to obtain data on the occurrence of Babesia bigemina e Anaplasma marginale in cattle with characteristic clinical signs of the disease, in different properties in western Santa Catarina. For this, 149 blood sample were collected and slides smears were done and the staining with the Romanowsky kind dye subsequently. Of the 149 samples surveyed, 78 (52.35%) were positive for A. marginale, 04 (2.68%) for B. bigemina, and 03 (2.01%) samples showed co-infection. All described cases occurred in adult animals, from two years old, with Holstein females the highest occurrence represented 119/149 (79.86%). Regarding the presence of ectoparasites, hematophagous flies were observed in all properties and ticks in 58/149 (38.92%) animals. The results showed a higher occurrence of A. marginale, evidencing the need to seek strategies of control and prevention by the veterinary professionals, especially in moments of greater occurrence of the vectors. The confirmation as from laboratory support by stained blood smears beyond being cheaper practical is a method that helping professionals identify the suspected cases etiology. Moreover, based on this information, we can promote the elaboration of prevention and treatment strategies based on simple and fast diagnostic techniques, focused on especific disease agents.

title: Prevalence and geographical distribution of bovine cysticercosis in the mesoregion of Northern Minas Gerais

description: ABSTRACT The knowledge of the prevalence of bovine cysticercosis is important for the implementation of control programs. The objective was to evaluate the prevalence and geographical distribution of bovine cysticercosis in Northern Minas Gerais. For that, 14,556 cattle were evaluated during the federal post-mortem inspection in 27 municipalities of five microregions: Janaúba, Montes Claros, Januária, Pirapora and Bocaiúva. The prevalence of Cysticercus bovis was 1.03% with distribution in all microregions evaluated of the northern Minas Gerais. All municipalities with a sampling number of cattle slaughtered above 543 showed positive animals for cysticercosis. The microregions of Bocaiúva, Montes Claros, Janaúba, Januária and Pirapora presented a prevalence of cysticercosis at 2.11%, 1.17%, 1.01%, 0.90% and 0.56%, respectively. The microregions of Montes Claros and Januária presented a greater chance of finding positive cattle for cysticercosis. As there are positive cases of cysticercosis in all microregions evaluated, there is a risk to human health.

title: Replacing corn with ground or pelleted citrus pulp in diets of Nellore heifers

description: SUMMARY Citrus pulp can replace corn in feedlot diets in order to decrease metabolic problems by reducing formation of lactate ruminal. However, while eating, animals can easily select against pelleted citrus pulp due to the greater particle size of the pellet. Therefore, grinding citrus pulp pellet can be an alternative to decrease particle selectivity. This study was realized to evaluate the replacement of ground corn by pelleted citrus pulp and ground citrus pulp on animal performance, sorting index, and feeding behavior of Nellore heifers. Thirty-six Nellore heifers were randomly assigned to three treatments: control diet based on ground corn (GC), partial replacement of GC by ground citrus pulp (GCP), and partial replacement of GC by pelleted citrus pulp (PCP). . Heifers fed with the GC diet had higher final body weight (BW), average daily gain (ADG), and dry matter intake (DMI) compared with heifers fed with citrus pulp (P &lt; 0.05). Ground citrus pulp increased DMI and fiber intake compared with the PCP group (P &lt; 0.05). Heifers fed with PCP and GCP sorted for diet particles from 8 to 19 mm and selected particles with less than 1.18 mm (P &lt; 0.05). Thus, the ground citrus pulp is better than pelleted citrus pulp due to higher feed intake and ADG, in consequence of lower selection index.

title: Estimates for digestible threonine: lysine for 21 - 35-day-old female meat-type quails

description: ABSTRACT Two assays were performed to estimate digestible threonine-lysine (Threo-Lys) ratio for female meat-type quails between 21 and 28 days old and between 28 and 35 days old. Experimental design was totally randomized. The first assay comprised 440 quails distributed into 5 treatments, 8 replications and 11 fowls per cage. The second assay comprised 280 quails distributed into 5 treatments, 8 replications and 7 fowls per cage. Five digestible Threo: Lys ratios were evaluated (0.66, 0.71, 0.76, 0.81 and 0.86). Performance, carcass and cut yield, chemical composition of carcass and nitrogen balance were evaluated. There was an improvement (P&lt;0.05) in feed conversion and increase in feed intake due to ratios of digestible Threo: Lys between 21 and 28 and between 29 and 35 days olds, respectively. At 35 days old, there was a better (P&lt;0.05) carcass yield and a negative nitrogen balance for Threo: Lys analyzed. A ratio of 0.86 may be recommended for digestible Threo: Lys as the best for feed conversion and carcass yield for female meat-type quails between 21 and 28 and between 28 and 35 days.

title: Subclinical hypomagnesemia: Prevalence and causes in dairy cows in the semiarid region of the state of Paraíba, Brazil

description: ABSTRACT In dairy farming, cows display important metabolic changes during the transition period, particularly high-production cows, which need nutrients in greater quantity to meet the required demand. The aim of this study was to determine the prevalence of subclinical hypomagnesemia in pre- and post-partum dairy cows inserted in milk-production systems in the Sousa microregion and the district of São João do Rio do Peixe, both in the State of Paraíba, Brazil. As such, visits were made every two weeks to 34 rural properties, where the team collected 357 blood samples by venepuncture, 106 from pre-partum lactating cows and 251 from lactating cows in the post-partum period. It was found that the properties supplied three types of mineral supplement: a single supplement of NaCl, a supplement of NaCl + mineral base, and a commercial supplement. The cows receiving the commercial mineral supplement had the highest prevalence (10.53%) of the disorder, even showing a significant difference (P &lt; .05) between the other types of supplement. In relation to reproductive period, it was found that the post-partum cows had a higher prevalence of subclinical hypomagnesemia (9.96%) than did the pre-partem cows (8.49%); there was, however, no significant difference (P &gt; .05) between the two. Studies such as this are fundamental for alerting rural and technical producers to the occurrence of subclinical hypomagnesemia in the region, in addition to the damage caused by metabolic disorders.

title: Morphological and yield responses of spineless cactus Orelha de Elefante Mexicana under different cutting intensities

description: ABSTRACT The objective was to evaluate the effects of different cutting intensities on the morphological responses and forage yield of spineless cactus Orelha de Elefante Mexicana (OEM) (Opuntia stricta (Haw.) Haw) in a 12-month cycle, receiving supplemental irrigation. Three cutting intensities were evaluated: cut preserving only the mother cladode (MOTHC), cut preserving primary cladodes (PRIMC), and cut preserving secondary cladodes (SECC), equivalent to initial residual cladode area index (rCAI) of 0.08, 0.33 and 0.69, respectively. The experiment was a randomized block design with eight replicates. The cutting intensities PRIMC and SECC resulted in higher plant height and width, total cladode number and cladode area index compared to MOTHC. The harvested plant weight, forage yield (t DM ha-1), forage accumulation rate and water use efficiency were greater for PRIMC and SECC in comparison to MOTHC. The forage yield for MOTHC was 20.92 t DM (dry matter) ha-1, while for PRIMC and SECC were 37.55 and 33.18 t DM ha-1, respectively. The final CAI was 1.23, 2.53 and 3.55 for MOTHC, SECC and PRIMC, respectively. Morphological and yield responses of OEM Spineless cactus under supplemental irrigation are influenced by cutting intensities, in which less intense cuts (preserving the primary or secondary cladodes) promote taller and wider plants, and higher forage yield.

title: Forage cactus (Opuntia ficus-indica Mill) meal in rabbit diets in the growth phase

description: ABSTRACT Two experimental tests were carried out to evaluate the inclusion of forage cactus meal in diets for rabbits during the growth phase. In the first test 14 male New Zealand red rabbits were used, housed in metal cages, and distributed in a completely randomly design with two treatments and seven replicates with one animal per experimental unit. The digestibility of the nutrients and the digestible energy of the forage cactus meal were determined by the total feces collection method. The forage cactus meal presented 92.24% of DM, 5.63% of CP and 2,347 kcal of DE/kg. In the second test the inclusion of 0, 10, 20 and 30% forage cactus meal in the rabbit diet was tested for productive performance, carcass characteristics, viscera and economic viability. Thus, 40 male rabbits of the New Zealand red breed were used, distributed in metal cages, completely random designed with four treatments, five replicates and two animals per experimental unit. No influence of inclusion levels (P&gt;0.05) on performance variables, housing characteristics or economic viability was observed. The forage cactus meal can be included in up to 30% in the diets of growing rabbits.

title: Effects of cutting height managements on yield and composition of different annual pastures

description: ABSTRACT This study aimed to evaluate the effects of different pre-cutting and residual heights of Pearl millet, Sudangrass, and Sorghum pastures on yield, morphological and chemical composition. The experimental design was the randomized blocks, with four experimental units per treatment. It was evaluated three species of forage: 1) Pearl millet (MIL; Pennisetum americanum); 2) Sudangrass (SUD; Sorghum sudanense); and 3) Sorghum (SOR; Sorghum bicolor); and two cutting managements: I) 50:20 - cutting height at 50 cm and 20 cm residual height; and II) 85:10 - cutting height at 85 cm and 10 cm residual height. Managements of cutting height affected neither forage yield per cut nor total forage yield. Sudangrass had less cuts than MIL and SOR when submitted to the 50:20 management. The 85:10 management increased stem proportion and leaf to stem ratio, and reduced leaf proportion in comparison with the 50:20 management. The 50:20 management reduced forage contents of fiber and organic matter, and increased forage contents of crude protein and total digestible nutrient. Sorghum exhibited greater nutritive value due to increased leaf proportion. The 50:20 management increased number of cuts and improved nutritive value of forages, regardless of species evaluated in this study.

title: Bromatological quality of silage from cassava residues: fractionation of proteins and carbohydrates

description: ABSTRACT The objective of this study was to evaluate the quality of silage in the upper third of cassava levels of inclusion of cassava peel, 0, 100, 200, 300, 400 g/kg out based on natural matter (NM) with 60 days of storage on fermentative profile, aerobic stability, chemical composition and protein and carbohydrate fractionation. The material was ensiled in 15 experimental silos, the experimental design adopted was completely randomised, with five treatments and three repetitions. The inclusion of cassava peel in silage from the aerial part of the cassava promoted an increasing linear effect for dry matter content. The contents of crude protein, neutral detergent fibre and acid detergent fibre decreased linearly (P &lt; 0.05) with the inclusion of cassava peel in the silage. The inclusion of the bark promoted an increase in carbohydrate levels. Protein and carbohydrate fractions were influenced by the addition of cassava peel, decreasing the unavailable and/or indigestible fraction (Fraction C) of proteins and carbohydrates. The inclusion of cassava peel up to the level of 400 g/kg NM in silage from the aerial part of the cassava improves the fermentation process, aerobic stability and the chemical composition of the silage, and reduces the indigestible fractions of carbohydrates and proteins.

title: Profit shifting in Brazil and the impact of tax havens

description: ABSTRACT We investigate tax-induced profit shifting in Brazil and the impact of tax havens on the shifting behavior of firms. Profit shifting research in Brazil is virtually non-existent, although the shifting incentives in Brazil are prominent. Our research fills this gap with evidences in the novel Brazilian context. Profit shifting is a tax-minimization strategy where multinational enterprises perform intra-firm transactions to allocate taxable profits to low-tax locations. Brazil combines a remarking set of profit shifting incentives, especially a high corporate tax rate, extremely complex tax system, and distinguished transfer pricing rules. Further researches may leverage from the shifting incentives in Brazil, since it provides opportunities to investigate additional factors that affect the shifting behavior of firms. We analyze 989 transaction-by-country observations for the period of 2010-2017. Baseline analysis follows the robust least squares approach with controlling covariates. Linear estimate model derives from the conventional Cobb-Douglas production function, to analyze the impact of shifting incentives on profit maximization. We find that Brazilian firms have a high level of intra-firm transactions with related parties located in low-tax countries, especially with tax havens. It represents a strong evidence of profit shifting behavior in Brazilian firms.
