This work aims to evaluate the morphology of Mangalarga Marchador foals with Factorial Analysis from August, 2000 to June, 2003. Nineteen linear measures relating to height, length, width and girth and 11 angular measures were made at birth’s week, in 55 colts and 41 fillies; at six months of age, in 35 colts and 37 fillies; and at twelve months of age, in 19 colts and 31 fillies. The factorial analysis was used to verify the existence of important relationships […]

This work aims to evaluate yield production and composition of milk of Mangalarga Marchador mares and average weight gain of suckling foals. Milk yield was evaluated in eight mares by the weigh-suck-weigh method, at intervals of two hour, twelve times a day. Daily milk produced was estimated by summing of the twelve observations. Milk yield was performed at 20, 40, 60, 80, 100, 120, 140 and 160 days of lactation. The milk was analyzed for lactose, protein, fat and energy […]

Apis mellifera honeybee brood rearing in laboratory conditions has been frequentely used to search for larval development, caste determination, and more recently for tests of pathogenesis. The amount and quality of food received by larvae during the feeding time can produce different castes (queen, worker or intercaste). In the present work, brood were reared from larvae with 18-24 hours old to adult bee stage and fed 4, 15, 25, 50 e 70 µl of a special diet . To determine […]

The effect of monensin on milk production, milk composition and body condition score of buffaloes cows in early lactation was evaluated. Twenty four Murrah buffalo cows were submitted to two treatments T1 (0 mg of monensin/buffalo cow/day) T2 (300 mg of monensin/buffalo cow/day) evaluated during the 150 first days of lactation. The total ration was composed by sorghum silage, elephant grass, and concentrate. The effect of monensin on milk production, milk composition and body condition score of buffaloes cows in […]

The objective of this experiment was to verify the effects of soybean oil and/or ethanolic extract of propolis, in the diets of dairy goats, on intake, on digestibility of nutrients, on milk production and composition and some ruminal parameters. Sixteen Alpine female goats were used, in which four animals fistulated in the rumen. The animals were allocated in four 4×4 Latin squares, in a 2×2 factorial arrangement of treatments. It was added to the concentrate 0 or 120 g of […]

This work was carried out aiming to evaluate the nutritive value of byproducts of fruit processor. Byproducts of pineapple, west indian cherry (WIC), guava, passion fruit and melon were evaluated. Twenty sheep castrated males, with average weight of 34.5 kg, were assigned to a completely randomized design with five treatments (byproducts) and four replications. Dry matter intakes (DMI) of byproducts of guava, passion fruit and melon by the animals were similar but higher than WIC byproduct. The highest crude protein […]

Six half-bred ½ Holstein-Zebu steers, fistulated in the rumen and abomasum, were randomly assigned to two 3 x3 Latin squares (animal, ingestion regime – 1.5, 2.0 and 2.5% LW and period) to determine the intake and total and partial digestibility of total carbohydrates (CHO), neutral detergent fiber (NDF) and non fiber carbohydrates (NFC). Chromic oxide was used as a marker to determine the digestibilities. Animals were fed diet with 60% Tifton-85 bermudagrass (Cynodon spp.) hay and 40% concentrate mixture (corn […]

Feed intake, partial and total digestibility and nitrogen balance were evaluated in confined steers. Three crossbreed steers, rumen and duodenum cannulated, were allotted to two 3 x 3 Latin square experimental design. The experimental diets were composed by corn silage (60%) and concentrate with sunflower meal as protein source and ground corn as energy source (MI). The ground corn was partially substituted by soybean hulls (CS) or by corn germ meal (FGM). Lignin and indigestible ADF (iADF), NDF (iNDF) and […]

Performance, plasmatic parameters and carcass traits of 24 3/4 Simmental 1/4 Nellore steers with 370 kg initial average weight was evaluated. The experimental diets were composed by corn silage (55%) and concentrate with sunflower meal as protein source and ground corn as energy source (MI). Ground corn was partially substituted by soybean hulls (CS) or by corn meal (FGM). The period of intake and average weight gain evaluation was 49 days. Blood samples were collected to measure plasmatic parameters: glucose, […]

This experiment was carried out to evaluate the dry matter ingestion, average daily gain, feed:gain ratio, live weight at slaughter and days in trial in pure Santa Inês and ½Dorset ½Santa Inês lambs, submitted to isoenergetic (76.59% TDN) and isoprotein (17.48% crude protein) diets with different sources of vegetable oil (soybean oil, canola and linseed) and a control diet (without vegetable oil inclusion). The forage:concentrate ratio was 30:70, and oat hay was used as forage. Digestibility analysis was performed, using […]
