1. Effect of Exogenous Protease, Mannanase, and Xylanase Supplementation in Corn and High Protein Corn DDGS Based Diets on Growth Performance, Intestinal Morphology and Nutrient Digestibility in Broiler Chickens
ABSTRACT A study was conducted to evaluate the effects of exogenous enzymes supplementation in high protein (Hi-Pro) corn DDGS-based diets on broiler growth performance, intestinal health, and nutrient digestibility. A total of 200 one-day-old broiler chicks were randomly allocated to four dietary treatments with five replicates of 10 birds each. A basal die

2. Optimal Available Phosphorus Levels in Diets Containing Different Dicalcium Phosphate Particle Sizes for Japanese Quails
ABSTRACT This experiment was conducted to investigate the effects available phosphorus levels and dicalcium phosphate particle size on the live performance, and egg parameters and bone parameters of Japanese quails in lay. The experimental diets were based on corn and soybean meal and formulated to contain 2900 kcal metabolizable energy (ME)kg-1, 200 g kg-1

3. Stabilization of Rice Bran in Broiler Feed with Natural and Synthetic Antioxidants and Heat Treatment
ABSTRACT The objective of this study was to evaluate different strategies for the oxidative stabilization of rice bran (RB) in the diet of broiler chickens using natural antioxidant additives, synthetic antioxidant additives and heat treatment on performance, breast meat quality and liver fat content and the nutrient digestibility coefficients. Furthermore,

4. Nutritional plans of digestible phosphorus for gilts from 30 to 100 kg
ABSTRACT The objective of this study was to evaluate sequential digestible phosphorus levels for gilts from 30 to 100 kg. Sixty gilts were used, with an initial weight of 29.98±3.37 kg and final weight of 100.66±8.82 kg, distributed in a randomized block design, with five nutritional digestible phosphorus levels: 2.19-1.88-1.68, 2.69-2.38-2.18, 3.19-2.88-2

5. Red clover silage: an alternative for mitigating the impact of nitrogen excretion in ovine production systems
ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20

6. Antioxidant action in diets with ground soybeans on ruminal microbial production, digestion, and fermentation in buffaloes
ABSTRACT The objective of this study was to evaluate the effect of adding ground soybeans and antioxidants to diet of buffaloes on intake, ruminal microbial production, total and ruminal digestibility of nutrients, and ruminal fermentation parameters. Four crossbred buffaloes with a mean weight of 506±29 kg were distributed in a 4×4 Latin square. Four diet

7. Increasing feed allowance in low-fish meal diets allows for a reduction in dietary methionine for juvenile Litopenaeus vannamei raised in green-water tanks
ABSTRACT A 10-week study was conducted to evaluate the effect of feed allowance and graded levels of dietary methionine (Met) on growth performance of Litopenaeus vannamei. Juvenile shrimp of 1.83±0.14 g were stocked in 42 outdoor green-water tanks of 1 m3 under 120 shrimp m−2. Animals were fed under two feed allowances, regular and 30% in excess. Five di

8. Purified glycerin in balanced diets of broiler chickens treated from 1 to 42 days of age
ABSTRACT We evaluated the technical feasibility of purified glycerin inclusion in balanced diets of broiler chickens treated from 1 to 42 days of age. A total of 240 broiler chickens were distributed in a completely randomized design into four treatments (0, 2, 4, and 6% purified glycerin inclusion), with six replicates of 10 broilers each. We evaluated prod

9. The effect of vinasse on the growth performance and feed digestibility of Holstein male calves
ABSTRACT. Industrial effluents of alcohol production are problematic for the environment. One of the proposed solutions to the reduction of harmful effects of the wastewater is to convert it into vinasse. The purpose of the present study is to investigate effects of rations with different levels of vinasse as a source of protein in the diet of 28 male Holste

10. Performance and digestibility of confined lambs fed with Babassu cake (Orbignya speciosa) as a substitute for elephant grass silage
RESUMO Objetivou-se avaliar a substituição parcial da silagem de capim elefante por torta de babaçu (Orbignya speciosa) sobre o desempenho, consumo, digestibilidade, composição química e ganho em peso de carcaça de ovinos. Cinquenta e quatro machos, castrados (19,08±2,76kg) foram distribuídos em delineamento inteiramente casualizado e administrado u

11. Suplementação proteica de vacas leiteiras mantidas em pastagem de Tifton 85 durante o período de seca
RESUMO Concentrados com alta proteína bruta e minerais e com menor concentração de energia poderiam ser utilizados em menores quantidades no balanceamento de dietas com volumosos tropicais. Assim, objetivou-se avaliar o consumo de matéria seca, a resposta produtiva e econômica de vacas da raça Girolando mantidas em pastagem de Tifton 85 durante o perí

12. Performance of crossbred lactating cows at grazing in response to nitrogen supplementation and different levels of concentrate feed
RESUMO Foi avaliado o desempenho de vacas mestiças (1/2 Holandês x Zebu) suplementadas em pastagens de Brachiaria decumbens durante o período de transição águas-seca. Oito vacas com 497±50kg, durante a terceira e a quarta lactação e após o pico de produção, foram distribuídas em dois quadrados latinos 4 x 4. Os tratamentos consistiram de um fato
