It was carried out two experiments, the first aiming to assess the effect of substituting elephant grass hay by spineless cactus and the second to evaluate the total replacement of corn and partial replacement of soybean by cactus and urea regarding to the ingestion behavior of sheep and lactating cows, respectively. In experiment 1, five mixed-breed non castrated male sheep with 25.8 kg average weight were distributed in a 5 x 5 latin square. In experiment 2, it was used […]

The experiment was carried out to evaluate the ingestive behavior of sheep fed diets containing elephant grass silage with different additives. Twenty sheep non-castrated male kids were used in a randomized complete design, with four treatments and five replications. The treatments were: elephant grass silage (control); elephant grass silage (75%) + coffee hulls (15%); elephant grass silage (75%) + cocoa meal (15%) and elephant grass silage (75%) + cassava meal (15%). The additives were added at ensilage moment was realized […]

Minerals, including trace-elements, and vitamins are currently introduced into the pig diet in order to obtain suitable performances for the modern pig genotype bred in confinement. Most of the mineral and vitamin contents of cereals and usual protein compounds are characterized by their poor and variable availability. Supplemental diets are then usually needed. This paper, based on literature data, reviews the pig requirement for minerals and vitamins in order to ensure economic and profitable performance. Recent research has focused on […]

This research was conducted with the objective of evaluating the use of different Maniçoba hay (Manihot glaziovii Muell. Arg) levels (30, 40, 50 and 60%) on intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), gross energy (GE), ether extract (EE), total carbohydrates (TCHT), non fiber carbohydrates (NFC), neutral detergent fiber (NDF), acid detergent fiber (ADF), water intake (WI), besides total digestible nutrients intake (TDNI). Eight multiparous Moxotó dairy goats with initial weight of 44,26 […]

The objective of this study was to evaluate the levels of concentrate for growing calves. Four Holstein × Brahman crossbred calves with average age of 7 months and 155 kg of body weight were used, distributed into one Latin square design (4 × 4). The animals were fed ad libtum in the form of complete diet containing levels of 20, 40, 60 and 80% of concentrate on the dry matter basis (DM). The diets were composed of Cynodon dactylon hay, […]

This study aimed to evaluate the effect of intraruminal infusion of propionic acid (RPA) associated to two (80:20 and 60:40) forage:concentrate ratios (FCR), for young bulls. Four Holstein × Zebu crossbred young bulls with average age of 7 months and 160 kg of body weight (BW) were distributed to a 4 × 4 Latin square design. A total mixed ration, isonitrogenous diets, was ad libitum fed to animals. The propionic acid was obtained by fermentation of reconstituted milk whey by […]

The effect of alfalfa hay processing (Medicago sativa L.) and the addition of soybean oil in diets on the total dry matter digestibility, organic matter, crude protein, ether extract, neutral detergent fiber and acid detergent in horses was evaluated. Four crossbred male foals with approximately 14 months of age and 197.25 kg were used and assigned in a (4 × 4) Latin square design with a factorial arrangement (2 × 2) composed of two alfalfa haying forms (cubes or branches) […]

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 of this work was to evaluate the effect of the levels concentrate of the diet on meat quality of no castrated male kid Saanen goats. Fifteen male goat with initial 16 ± 0.3 kg BW and four months old were fed diets formulated with 80, 65 e 50 of concentrate up to the animals reached a final a 22 kg BW. The rations were formulated to promote a weight gain of 150g/anim.day. Centesimal composition, colour, texture, lipid and […]

The experiment was carried out to evaluate the ingestive behavior of sheep fed diets containing cocoa meal. Sixteen Santa Inês female sheep, no-pregnant, no-lactating, averaging 25 kg of body weight and 12 months of age, maintained in individual barns were used. The cocoa meal was fed in the concentrate at the levels of 0, 10, 20 and 30%, and as forage was cassava aerial part hay. The diets were offered in total mixed ration, in 50:50 forage:concentrate ratio. Feeding, ruminating […]
