The objective of this study was to evaluate the performance and the gross margin of profit of lambs finished in feedlot. Thirty-two no castrate male lambs from the genotype Santa Inês and crossbred Dorper × Santa Inês and two body condition, intermediate and fat, were used. The lambs were 16 Santa Inês (SI) and 16 ½ Dorper × ½ Santa Inês (DpSI), with average 103 days old and 20.0 kg BW. The lambs were full fed ration with 30% of […]

The objective this study was to evaluate the correlation between traits obtained real time ultrasound and those obtained in the carcass of feedlot finished lambs. Forty eight no castrated, woolless crossbred Santa Inês lambs with initial 20.0 kg LW and 103 days old. The measures obtained by ultrasound in real time were determined using by Aloka 500SSD ultrasound machine, equipped with 3.5-MHz linear transducer. Before the slaughter, using the real time ultrasound, were measured between at 12th – 13th ribs […]

The objective of this research was to evaluate the effect of inclusion (0, 20, 30 and 40%) of whole cottonseed (Gossypium hirsutum) in the diet on chemical composition and fatty acids profile of Santa Inez sheep meat. Twenty four no castrated male sheep were used, (initial 19.0 ± 0.2 kg BW and 4 month old), all kept in confinement regime in individual stalls. The levels of whole cottonseed did not affect chemical composition and the percentages of cholesterol and phospholipids […]

The objective was to evaluate the performance of lactating water buffalo fed diets with different fat sources. Twelve lactating water buffaloes were randomly distributed in four diets: without additional fat, soybean seed, cottonseed and soybean oil. The experimental period was 84 days, with four periods of 21 days (14 days for diet adaptation and 7 days for sample collections. The diets were fullfed, twice daily, as total mixed ration. At sample collections period, milk yield (kg/day) and 4% fat corrected […]

This research was to evaluate the effect of Leucaena (Leucaena leucocephala) and yeast (Saccharomyces cerevisiae) in diets for bovines on ruminal metabolism, including pH, volatile fatty acids, and ammonia and methane production. Four crossbred male cattle (800 kg LW) rumen cannulated were distributed to a 4 × 4 Latin Square design, in 2 × 2 factorial arrangement, composed by two levels of Leucaena (20% and 50% DM) and coast-cross grass hay, with or without yeast. No differences were observed in […]
