One experiment was conducted to study the effect of the substitution of dry skim milk for isolated soybean protein in diets of piglets from 21 to 35 days of age. It was used 80 piglets in a experimental design involved 5 treatments, 4 blocks of 4 animals each in a total of 16 piglets per treatment. The treatments constituted the levels of substitution (0%, 25%, 50%, 75% and 100%) of the protein furnished by dry skim milk for isolated soybean […]

The objective of this study was to evaluate the effects of stocking density and strain on performance, carcass yield and cuts and quality parameters of breast meat (cooking weight loss, shearing force and pH) of broilers chickens. Two thousand and nine hundred and twenty five day-old chicks were alocated in a randomized 3x3x2 factorial design, with tree commercial strains (Ross 308, Cobb 500 and Hybro PG), three densities (10, 13 and 16 birds/m2) and two sex with two replications with […]

Two experiments were carried out to study the effect of the normal (15%) or high (24%) starch level on the digestibility and performance in growing rabbits from four feeding patterns until weaning. For the digestibility assay, 96 White New Zealand from 35 to 49 days of age, were allotted to a factorial design 2x2x2 (two milk intake patterns versus two starch levels before weaning versus two starch levels in diet after weaning), with eight treatments and 12 replicates. Animals from […]

It was evaluated chemically and biologically the powdered fruits pulp residue, used in human food industry. In the digestibility study it was used 12 commercial hybrids barrows piglets, with initial weight 12,2 ± 1,6 kg, allotted in individual cages. The treatments were a basal and a test diet. In the test diet the fruits pulp residue replaced 30% of the basal dry matter. The following values were obtained: dry matter 89,54%, starch 71,1%, glucose 5,4%, fructose 2,2%, crude protein 5,33%, […]

The experiment was carried out to study the influences of the feeding pattern of rabbits during the lactation phase according function of the starch level in the diets and availability of milk modulated by litter size on performance young rabbits before weaning (35 days). One hundred litters were maintained to eight rabbits at birth until the 16 day old. From 16 to 35 days old, 60 litter were reduced for four young rabbits, while the others were maintained with eight […]

This work was undertaken to evaluate of dietary energy and energy: crude protein ratio on performance and carcass quality of broiler chicks in the pre-starter and starter phases. Were used 900 one day old male broiler chicks, weight of 41 g, allotted in a completely randomized design in 45 boxes, in factorial 3 X 3, with three ME levels (2,850; 3,000 and 3,150 kcal) and three ME: CP ratio (125.0, 136.9 and 151.5 kcal/%CP), resulting in nine treatments with five […]

This study was conducted to evaluate the effect of 0.0, 3.3, 6.6, and 9.9% soybean oil inclusion in isoenergy diets on transit time (TT), performance, carcass characteristics and body composition of broilers from 21 to 56 days of age. The TT was determined at 22 and 42 days of age. Eight hundred and fourty broilers, with initial average weight of 870 g, allotted to a completely randomized design, with four treatments, six replications and 35 broilers per experimental unit, were […]

This trial was carried out in Luiziana, Northwest of Paraná, from June to October 2000. Twenty-four animals with 223 kg of initial body weight and nine months old, from two different genetic groups, ½ Red Angus ½ Nellore (15) and ½ Marchigiana ½ Nellore (9), were used. Animal performance was evaluated, under grazing conditions of Coastcross (Cynodon dactylon (L.) Pers) and three types of supplementation: grazing Oat + Ryegrass pasture (OR) for four hours/day; 1.2% of body weight (BW) supplement […]

A study was conducted to determine the effect of environmental stress on physiological criteria of feedlot sheep. Treatments consisted of two different housing conditions (shade and no shade) and two levels of concentrate in the diet: high concentrate (70% of concentrate and 30% of roughage-70C:30R); low concentrate (30% of concentrate and 70% of roughage-30C:70R). Animals raised under shade and fed a high concentrate diet (70C:30R) had greater dry mater intake (1258 g/animal/day) and crude protein (0.8% of body weight (BW) […]

This trial was carried out in Luiziana, northwest of Paraná, from November 2000 to February 2001. Twenty-four animals with 325 kg of initial body weight and 13 months of age, from two different genetic groups, ½ Red Angus ½ Nellore (20) and ½ Marchigiana ½ Nellore (12) were used. Animal performance was evaluated, under grazing conditions on coastcross (Cynodon dactylon (L.) Pers) and four levels of soybean hulls: 0, 0.2, 0.4, and 0.6% of body weight. Pasture production and quality […]
