The objective of this study was to evaluate the genotype effect on the morphometric and quantitative characteristics of carcasses of kids and lambs finished in feedlot. A total of 34 entire male animals was used, 12 kid goats (½ Boer ´ ½ SRD), 12 kid goats (½ Anglo Nubiano ´ ½ SRD) and 10 Santa Inês sheep, with initial live weight of 18.3 kg, average age of 135 days at the beginning of the trial. The averages of withers height, […]

The objective of this study was to evaluate the effects of the genotypes and body condition on the carcass dressing of lambs finished in feedlot. Twenty-four Santa Inês and 24 ½ Dorper × ½ Santa Inês crossbred lambs averaging 19.8 kg of weight and 103 days old were used in the trial. The adaptation period to the facilities and diet was of 14 days. The animals received complete ration with 30% of maniçoba hay (Manihot pseudoglaziovii) and 70% of concentrate. […]

The objective of this trial was to determine the effects of feeding diets containing citrus pulp on carcass characteristics and meat quality of feedlot lambs. Thirty-two Santa Ines lambs were distributed in a complete randomized block design according to body weight and age at the beginning of the performance trial. Lambs were fed diets containing 90% concentrate (corn and/or citrus pulp, soybean meal and minerals) and 10% coastcross hay (Cynodon spp). Citrus pulp was added at levels 23.7, 46.1 and […]

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 aim of this study was to evaluate the performance of sheep supplemented with phosphorus (P) using carcass traits and analysis of 12th rib. Twenty male lambs weighing 13.88 ± 2.51 kg and grazing Andropogon gayanus pasture were divided in two treatments of 10 animals each. In group P, animals were supplemented with 3 g phosphorus/animal/day, while in group NP no P supplementation was given. After 82 days the animals were slaughtered and carcass measurements were taken. The 12th rib […]

The objective of this study was to evaluate the meat centesimal composition of Santa Ines pure breed and Santa Ines vs Texel crossbreed lambs, slaughtered at different body weights. Thirteen males and fourteen females from both breeds were selected. The muscle biceps femoris was used to determine water, crude protein, crude extract and minerals contents. The experiment was arranged randomly, with 16 traits in a 2x2x4 factorial scheme with two genetic groups, two genders (14 males and 13 females in […]

Sixteen Santa Inês sheep were randomly allotted to four treatments (T0 = 81% tifton hay (TH) and 19% concentrate (soybean meal and corn); T27 = 27% egeria hay (EH), 54% TH and 19% concentrate; T81 = 81% EH and 19% concentrate) to evaluate the effect of Egeria hay inclusion in the diet on voluntary intake, weight gain and feed efficiency. Voluntary intake reduced and body weight gain was not affected by EH inclusion. During the experimental period, weight gain was […]

Twenty-one lambs were used, nine of the Bergamácia and 12 Santa Inês breed, were confined individually for 75 days, and fed diets containing 24% of swine wastes, in the form of biju (obtained by the scratching and sweeping of the floor of the growth and termination stalls) or DSW – dry sifted wastes (constituted by the solid part of the material contained of the water of wash of the stalls, obtained through sieves of fine mesh). There was no diet […]

This study aims to estimate genetic and phenotypic parameters for the Morada Nova, Santa Inês e crossbred Texel x Morada Nova in Federal District of Brazil. Data were available on 2337 lambings over a period of 14 years (1986 to 1999) from a commercial holding for meat production. The herd had no fixed breeding season. The effects of sex, number of lambs per lambing, month and year of lambing were determined for weights at birth, 30, 120 and 210 days […]

The work was conducted with the objective to study the allometric growth of the bone, muscular and fat tissues in the left side of growing lamb carcasses. Thirty-six, twenty-four Santa Ines and twelve Bergamacia lambs were used. The animals were kept in individual pens and fed ad libitum diets. The slaughtering was done when the animals reached the live weight of 15, 25, 35 and 45 kg. The amount of the different tissues was obtained through the dissection of the […]
