Seven hundred and twenty and six hundred chicks, males and females, from 22 to 42 and from 43 to 53 days old, respectively, fed a basal diet (3100 and 3210 kcal ME/kg and 19.6 and 18.6% CP) deficient in sodium (0.017%), supplemented with NaCl, corresponding to the levels of .077, .137, .197, .257 and .317% of total sodium were used to determine the sodium requirements for broilers during the growing and final phases. A completely randomized design, in a 5×2 […]

Eight hundred and sixty-four and 720 broilers, 50% of each sex, from 22 to 42 and from 43 to 53 days of age, respectively, were used to determine the available phosphorus requirement for male and female broilers in the growing and finishing phases. Six supplementary levels of available phosphorus were added to available phosphorus deficient basal diets. The levels of available phosphorus added in (.0, .09, .18, .27, .36 and .45%) for the growing and (.0, .07, .14, .21, .28 […]

A trial was carried out to evaluate the effect of low crude protein (CP) diets, supplemented with amino acids, on the starting barrows performance. Forty barrows genetically improved, of commercial dam line, were allotted to an experimental randomized complete block design, with four treatments, five blocks and two animals per experimental unit. The four treatments were: 18.73% P .96% L – corn-soybean meal diet containing 18.73% of CP and 0.96% of digestible lysine; 16.86%P + L – it was constituted […]

The objective of this work was to study the effect of dietary ME levels on the performance and the energy metabolism of male broilers on growing phase, from 22 to 43 days old. Two hundred and eighty-eight broilers were ramdomly assigned to three energy levels (3,050; 3,200 and 3,350 kcal/kg) and three feeding levels (ad libitum, 75% and 50% ad libitum), with four replicates of eight birds, to determine the energy maintenance requirements and the energy efficiency utilization. The method […]

The use of defatted corn germ meal (DCGM) for swine feeds was evaluated by two experiments. The first experiment was represented by a digestibility test with two treatments and four replicates, where eight pigs were allocated in metabolic cages during 12 days and submitted a total feces and urine collect. The second experiment aimed to evaluate the performance on growing I (20 to 50 Kg live weight), growing II (50 to 80 kg live weight) and finishing (80 to 100 […]

Forty eight commercial hybrids, barrows and females with 5.47 ± 0.21 kg, were allotted to a randomized block design with four treatments and six replications, to determine the best lysine level until 11.9 ± .35 kg and subsequent effects at 19.0 kg. The chemical composition of body fractions and the carcass and empty body accretion rates were determined. The studied digestible lysine levels in the nursery phase were 1.16 at 1.46%. No effects were observed on the chemical composition of […]

This work was carried out to evaluate angular measures of foals, from birth to 12 months age, and mature animals of the Mangalarga Marchador horse. Eleven angular measures of 98 foals, 55 males and 43 females, were taken on the birth day and at each thirty days up to complete 12 months of age. Results of measures were submitted to analysis of variance and mathematical model included effects of sex, region, nutritional management, herd, month and year of birth. The […]

This work aims to evaluate the relationships between body measures of foals from birth to twelve months of age and mature animals of Mangalarga Marchador breed. Measures were body weight and measures of height, length, width, girth of animals. Corporal Index (CI), Meloscopic Index (MI), Dactilo-thoracic Index (DTI) and Weigth in Cannon Index (WCI) were used to evaluate the relationship between measures. The Eclectic System of Linear Proportions was used to evaluation the proportions between linear measures and head length. […]

The objective of this experiment was to evaluate the food intake, food conversion and weight gain of Braford calves, weaned with 88 days of age, fed with triticale silage associated to 35, 45, 55 or 65% concentrate, dry matter basis. The animals were fed ad libitum, twice daily with the 15% CP diet. The experiment was conducted during 84 days, divided in four periods of 21 days. Average daily intakes of dry matter (DMI) expressed in kg (DMID), per 100 […]

Two levels of protein and mineral supplements (290 and 400 g.an.-1.day-1) were evaluated and compared with the mineral supplement in 90 Nelore steers on star grass pasture (Cynodon plectostachyus Pilger) during the winter. The supplement intake was ajusted by the concentration of sodium clore into the mixture. Considering the first 28 days (adaptation period) in the statistical analysis, there was no difference in average daily gain (ADG). Taking out this period of adaptation, the ADG was better for the protein […]
