The objective of this study was to evaluate morphometric measures, carcass yields, absolute weights and yields of commercial cuts of carcass of kids with no defined breed. Eighteen castrated male goats, with average weight of 15 kg were used. The experimental period lasted 105 days. The experimental design was completely randomized; animals were allocated to three treatments: free grazing without supplementation; restricted grazing without supplementation and free grazing with supplementation. Animals were supplemented (1% of body weight) with forage cactus […]

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 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 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 […]

Twenty-five crossbred Holstein-Zebu cows was used to evaluate the effect of body condition score at calving on milk yield and composition and evaluate the body reserves mobilization by variation of body condition score during the first 120 days of lactation. The cows were allocated in two classes according to the body condition score at calving (BCSC), using a scale from 1 (very thin) to 5 (very fat): class 1, cows with of BCSC > 3.25; and class 2, cows with […]

The productive performance of Holstein cows grazing fertilized coastcross (Cynodon dactylon (L.) Pears) pasture, strategically irrigated and supplemented with either 3 or 6 kg of concentrate/cow/day, was evaluated in this trial. The data were collected for three years (October/2000 to October/2003), involving 108 lactations. A completely randomized block design with two treatment replications was adopted, with nine animals per paddock. The pasture was strip grazed at a stocking rate of five cows per hectare, with rest periods of 25 and […]
