Chemical composition and fermentative losses of mixed sugarcane and pigeon pea silage Animal Sciences
Pereira, Djalma Silva; Lana, Rogério de Paula; Carmo, Davi Lopes do; Costa, Yanna Karoline Santos da.
Adding legumes to sugarcane silage is a strategy used to improve silage quality and reduce losses. This study’s objective was to evaluate the chemical composition and fermentation profile of silages sugarcane and pigeon pea. A completely randomized design was used, with five treatments and four replications. The treatments consisted of sugarcane silage with increasing pigeon pea proportions (0, 25, 50, 75 and 100%). The forages were ensiled in experimental microsilos that remained closed for 60 days. Their chemical compositions were evaluated by determining the pH value and dry matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose and lignin content. Fermentation profiles were evaluated by determining the effluent,...

Nitrogen compounds balance and microbial protein synthesis in supplemented crossbred dairy cows in pasture Animal Sciences
Gutierrez, Gabriela Santistevan; Lana, Rogério de Paula; Teixeira, Cesar Roberto Viana; Rennó, Luciana Navajas; Veloso, Cristina Mattos.
The objective this work was to evaluate the supplementation of cows on Brachiaria decumbens pasture during the rainy-dry transition. Eight 1/2 Holstein/Zebu cows (497 ± 50 kg) were distributed in two 4 x 4 Latin squares, with 2 x 2 factorial treatments (100% mineral salt versus nitrogen salt containing 25:25:50% urea: corn: mineral salt, and 1.5 versus 3.0 kg d-1 concentrate per cow). The experiment lasted 56 days, divided into four periods of 14 days, the last seven days for data collection. No interaction effect (p > 0.05) was detected between the supplement and the different levels of concentrate for any of the evaluated variables. No effect (p > 0.05) of supplement or concentrate level was observed on urinary excretions of purine derivatives,...

Performance of Holstein-Gyr crossbred heifers on pasture of Brachiaria decumbens supplemented with multiple supplement or proteined salt Animal Sciences
Santos, Ronald Matos dos; Lana, Rogério de Paula; Teixeira, César Roberto Viana.
 This study aimed to evaluate the performance, efficiency and economic viability of different supplements for dairy heifers on Brachiaria decumbens pasture. Twelve heifers with 186 ± 30.5 kg average weight were divided in three groups of four animals. The treatments were mineral salt ad libitum; 0.4 kg animal-1 day-1 proteined salt and 1.0 kg animal-1 day-1 multiple supplement. The experimental design was randomized blocks, with the contrasts considered significant at 5% probability. There was greater (p < 0.05) body weight and higher daily weight gain in animals supplemented with proteined salt or multiple supplement, compared to supplemented with mineral salt. There was no difference (p > 0.05) in any of the performance parameters between proteined...

Protected fat and variable level of protein in diets of crossbreed cows in early lactation Animal Sciences
Souza Júnior, Alcy Heleno de; Lana, Rogério de Paula; Teixeira, César Roberto Viana; Gionbelli, Mateus Pies; Veloso, Cristina Mattos; Rennó, Luciana Navajas.
Current study evaluated the inclusion of protected fat and different levels of crude protein (CP) in the diet of crossbreed cows in early lactation. Twelve cows were distributed in a 4 x 4 factorial design, with four treatments (12 or 16% CP, with or without MEGALAC-E®). Statistical analyzes with ANOVA and Pearson’s linear correlation procedures were performed. Protected fat did not affect intake of dry matter (DM) and organic matter (OM) (p > 0.05). Increased CP raised consumption of CP and EE and decreased the non-fiber carbohydrates (NFC; p <0.05). Protected fat increased (p <0.05) the digestibility of DM, OM, CP and ashes in the lower protein content. CP increase raised the level of blood and urinary urea (p < 0.05). There was no difference...

Sugarcane with Elephant grass replacing sugarcane with urea in the diet of crossbred dairy cows1 Animal Sciences
Teixeira, César Roberto Viana; Lana, Rogério de Paula; Gomes, Luiz Henrique dos Santos.
The objective was to evaluate the partial substitution of sugarcane treated with urea by elephant grass in the feeding of crossbred cows in lactation. Eight crossbred cows (Holstein x Gyr) were used, with 474 kg of body weight (standard deviation = 46.15 kg) and 8.15 kg of milk per day. The animals were housed in individual stalls, distributed in two 4 x 4 Latin squares, and the treatments were: sugar cane; sugar cane corrected with 0.5% of urea and ammonium sulfate (9:1); 75% of sugar cane + 25% of elephant grass and 50% of sugarcane + 50% of elephant grass, based on natural matter. In addition to the treatments, it was provided water and mineral salt ad libitum and 3 kg of concentrate supplement (24% crude protein), based on corn meal and soybean meal,...

Urea and salt as supplementary diet for crossbreed milk cows Animal Sciences
Teixeira, César Roberto Viana; Lana, Rogério de Paula; Rennó, Luciana Navajas; Veloso, Cristina Mattos; Carvalho, Juliana do Carmo; Menezes, André Azevedo de.
This study aimed to evaluate the use of supplementary feed with different percentages of urea and mineral salt for crossbred milk cows. Ten animals were used, mean body weight 480 kg ± 9,7, distributed in a 5 x 5 double Latin square, with treatments of supplements with different urea and mineral salt percentages, namely, 10:10; 10:20; 20:10 and 20:20, completed to 100% with corn meal. Data underwent statistical analysis by SAS at 0.05 significance level. The use of supplements increased (p < 0.05) the total dry matter (DM) intake of diet. The increase in the level of urea in the supplement decreased DM intake of supplement. The use of supplements increased (p < 0.05) DM digestibility. The treatments with presence of supplement showed higher (p <...
