Digestibility and nitrogen balance of lambs fed sugarcane hydrolyzed under different conditions as roughage in the diet Ciência Rural
Endo,Viviane; Sobrinho,Américo Garcia da Silva; Almeida,Fabiana Alves de; Lima,Natália Ludmila Lins; Zeola,Nivea Maria Brancacci Lopes.
This study aimed to evaluate the digestibility and nitrogen balance (NB) of lambs fed sugarcane hydrolyzed under different conditions. Fifteen Ile de France lambs at, on average, 23.5kg of body weight were evaluated. Treatments were: in natura sugarcane (IN), sugarcane hydrolyzed using 0.6% calcium oxide (CaO) under aerobic condition (AER), and sugarcane hydrolyzed using 0.6% CaO under anaerobic condition (ANA). Therefore, a completely randomized design was constituted with five replicates per treatment. Treatments were supplied to animals along with concentrate. Both hydrolysis conditions aimed to alter the sugarcane fermentation pattern, therefore improving fiber digestibility. Lambs were housed in individual pens and fed with diet allowing 10% of...

ABSTRACT The objective of this study was to evaluate residual feed intake (RFI), residual intake and body weight gain (RIG) and their relationship with other traits of efficiency, performance, and economic analysis of sheep. Lambs (n = 102) were evaluated during 56 days and a herd consisting of 500 ewes was simulated with the mean of dry matter intake (DMI) and final body weight of the lambs, the same as that of the experimental lambs. The lambs were fed hay-based diet of Tifton 85 (Cynodon spp.), corn, and soybean in the voluminous:concentrate ratio of 35:65. Residual feed intake and RIG were correlated with DMI, feed conversion ratio, and feed efficiency. Residual intake and body weight gain were positively correlated with average daily gain, relative...

Sales,Ronaldo Oliveira; Silva Sobrinho,Américo Garcia da; Zeola,Nivea Maria Brancacci Lopes; Lima,Natália Ludmila Lins; Manzi,Gabriela Milani; Almeida,Fabiana Alves de; Endo,Viviane.
The objective of the study is to evaluate meat quality from Ile de France lamb fed diets supplemented with sunflower seeds and vitamin E. Thirty-two lamb weighing initially 15kg were housed in individual stalls and slaughtered when body weight reached 32kg. The treatments consisted of four experimental diets: D1) sugarcane + concentrate without sunflower seeds; D2) sugarcane + concentrate with sunflower seeds; D3) sugarcane + concentrate without sunflower seeds plus 1000mg vitamin E kg-1 diet dry matter (DM); and D4) sugarcane + concentrate with sunflower seeds and 1000mg vitamin E kg-1 diet DM. The parameters temperature, pH, color, cooking loss, shear force and water holding capacity were determined at maturation times of 0, 7 and 14 days on the...

Performance and carcass characteristics of Santa Inês pure lambs and crosses with Dorper e Texel at different management systems R. Bras. Zootec.
Garcia,Iraides Ferreira Furusho; Costa,Tharcilla Isabella Rodrigues; Almeida,Amélia Katiane de; Pereira,Idalmo Garcia; Alvarenga,Flávio Augusto Pereira; Lima,Natália Ludmila Lins.
It was evaluated the performance and the carcass characteristics of 36 non-castrated male lambs, Santa Inês purebreed and crossbreeds from Dorper × Santa Inês and Texel × Santa Inês, managed in three different systems (intensive, semi-intensive and extensive), slaughtered at 38.41 ± 1.24 kg. It was observed the highest weight gain for lambs reared in intensive system, which also showed the greatest carcass yield. The management systems did not influence carcass measures of animals in intensive system much because of the greater weight of the carcass. The intensive system provided the best performance, regardless the genetic group. The use of Texel and Dorper breeds in crossings with Santa Inês increases carcass yield.

Quantitative and qualitative characteristics of the non-carcass components and the meat of lambs fed sunflower seeds and vitamin E R. Bras. Zootec.
Lima,Natália Ludmila Lins; Silva Sobrinho,Américo Garcia da; Almeida,Fabiana Alves de; Endo,Viviane; Zeola,Nivea Maria Brancacci Lopes; Almeida,Amélia Katiane de; Sampaio,Alexandre Amstalden Moraes.
The objective of this investigation was to evaluate the weight and percentage of the non-carcass components and the mineral content (macro minerals and trace minerals), crude protein, ether extract, moisture and vitamin E of the heart, liver, tongue, lungs, reticulum, kidneys and meat from the longissimus dorsi of lambs in feedlot finishing. Thirty-two non-castrated Ile de France male lambs, fed diets containing sunflower seeds and vitamin E from 15 to 32 kg of body weight were allotted in a completely randomized design in a 2 × 2 factorial arrangement. The weight of the gastrointestinal tract was higher in the lambs fed diets containing vitamin E (10%). No difference was observed in the liver as to the mineral matter, crude protein, ether extract,...
