Nutritional effects of two levels of L-glutamic acid (L-Glu) combined with four levels of vitamin K (vit. K) in serum and the liver of chicks of day-old broilers, male, Hubbard, raised in brooded batteries, receiving basic purified diet supplemented with 6.25 and 12.5% of L-Glu combined with 0.02, 0.2, 2.0 and 20.0 mg vit. K/kg. Two hundred and fifty birds were allotted to completely randomized design an in 2 × 4 factorial arrangement, with four replications of eight birds each. […]

Data from 12.840 litters, recorded from 1989 to 2003, were used to evaluate genetic parameters and genetic trends of reproductive traits in Large White pigs. Data were provided by the Swine Breeders Brazilian Association – ABCS and included records on litter size at birth (NLN), litter size at 21 days (NLD), average litter weight at birth (PMNasc), litter weight at weaning adjusted to 21 days (PMD), average daily weight gain (GMD) and number of stillbirth (NatMort). Variance components were estimated […]

The aim of this paper was to evaluate and to publish the study on the evolution of the relation between the total amount of submitted proposals and the supported ones, into the National Council for Scientific and Technological Development (CNPq)’s Animal Science Support Program subareas. The study was based on data from the last three Universal Calls (01/2002, 019/2004, and 02/2006) and evinced regional distribution of such variables. Data were obtained through CNPq’s Oracle® database, using PL-SQL search tool. From […]

It was evaluated the shading effect induced by two tree densities of a ten-year-old slash pine (Pinus elliottii Engelm.) forest, and at full sun, on forage dry matter yield and nutritive value of three cool-season annual grasses. Treatments were a combination of two main factors: a) three light conditions induced by two tree densities (333 e 555 stems/ha) and at full sun; b) three cool-season annual forage grasses: Italian ryegrass (Lolium multiflorum Lam.), common oat (Avena sativa L.) cv. Fapa-2, […]

The population dynamics of tillers and tissue turnover were investigated in pastures of Pennisetum purpureum Schum. cv. Cameroon submitted to different stocking rates under rotational stocking. Two experiments were carried out and the experimental area was characterized by a mean annual rainfall of 1,311 mm and average temperature of 25ºC. In the rainfall period the stocking rates were 3, 4, 5, and 6 steers/ha; in the dry period the stocking rates were 2, 3, 4, and 5 steers/ha. The most […]

Twenty-six Moxotó non-castrated males kids, with average 15 kg BW and 7 to 8 mo old, were fed a diet containing 2.6 Mcal/kg ME were used to evaluate the body composition and energy requirements for weight gain. At the beginning of the experiment, six animals were slaughtered as a reference to estimate initial body composition and initial empty body weight (EBW). While, the remaining animals (four groups of five animals, one for each feeding regime, were distributed to a completely […]

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 […]

Two experiments were carried out to evaluate the dry matter, crude protein and gross energy digestibilities and the performance of rabbits fed simplified diets based on forages. In digestibility assay, 45 New Zealand white rabbits with 1,550 kg of initial weight and 50 days old were distributed to a completely randomized design with 3 diets and 15 replications. Three diets were used: a reference-diet and two simplified diets (one with alfalfa hay and other with upper third part of foliage […]

An experiment was conducted with the objective to evaluate the performance and quality of eggs from meat quails from two genetic groups during 84 days of experiment. A total of 98 birds averaging 258 kg and 40 days old was assigned to a completely randomized design with two genetic groups (A and B) and seven replications of seven birds each. The evaluated characteristics were: diet consumption (g/bird/d), average egg weights (g), laying per bird per day (%) and per lodged […]

This work aimed to evaluate the forage value of a brown-seed grass (Paspalum plicatulum) population, considering bromatological aspects and dry matter accumulation. Plants were obtained from tussocks and they were established in a weed-free area 80 cm apart from each other. The experimental design was completely randomized and treatments consisted of plant age after establishment characterized by days (D) and degree-days (DD) accumulated above 0ºC. Harvests were performed at ground level in late-spring (27 D, 587 DD), mid-summer (68 D, […]
