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 […]

Four hundred male Cobb chicks were used in an experiment to study the effects of different dietary levels of garlic and copper on the performance, carcass characteristics and serum and tissue cholesterol levels of broiler chicks. The experimental period was comprised between the first 21 days of age of the birds. A completely randomized design was used in a factorial 3 × 3 with the following levels: garlic (0, 1.5, and 3.0%) and copper (0, 125, and 250 mg/kg of […]

This experiment was carried out to evaluate the influence of the linseed oil addition in replacement of soybean oil in laying hens diets on performance and internal and external egg quality. A total of 192 laying hens Bovans Godline line with 29 week-old, were distributed to six treatments, that consisted of a control diet (without vegetal oil) and of five diets containing 2% of linseed oil in replacement of 0, 25, 50, 75 and 100% of soybean oil, generating levels […]

The objective of this trial was to evaluate carcass characteristics, cuts yield, tissues proportion, and chemical composition and fatty acid profile of the Longissimus dorsi of feedlot kids fed diets, in which soybean hulls (SH) replaced ground corn grain (GCG). Fifteen Boer x Saanen male kids were assigned to a completely randomized design (five animals per treatment) and slaughtered at 33.82 ± 4.40 kg of body weight. Diets were composed by star grass hay (Cynodon spp), soybean meal, GCG and/or […]

The objective of this experiment was to compare fat and cholesterol content, and fatty acids (FA) profile in Longissimus dorsi muscle of castrated and young bulls from Nellore (NE) and ½ Nellore x Sindi (NS) cattle and Mediterranean buffaloes. Eight animals (four castrated and four young bulls) per genetic group was used, with a total of 24 animals. A completely randomized experimental design in a 3 x 2 factorial arrangement (three genetic groups and two sexual conditions) was used. Animals […]

To evaluate the effect of a hiperlipidemic diet on the reproductive performance, lipidic metabolites and serum progesterone levels, 42 Holstein-Zebu crossbred cows were submitted to two treatments: T1 (n=21), control diet, and T2 (n=21), hyperlipidemic diet, consisting mainly on whole soybean. The mean intervals to the first and second postpartum ovulations were 26.3 and 35.9 days for animals of T1 and 21.7 and 37.4 days for those of T2. The average intervals from calving to onset of the luteal activity, […]
