Two experiments (EXP) were carried out with 49 and 65 kg barrows (EXP 1 and 2, respectively) to determine digestible energy (DE) values of three sources of blood meals (EXP 1): conventional (CBM), flash dried (FDBM) and spray dried red blood cells (SDRBC), and of three poultry by-product meals (EXP 2) (PBM-10.1, PBM-12.7, and PBM-16.7% of ash content) by an alternative method to the replacement method (SbM). The method was based on the starch basal diet replacement with increasing levels […]

The apparent digestibility coefficients of DM, protein and energy of five ingredients (soybean meal, corn gluten meal, fish meal, broken rice and ground corn) were determined for jundia juveniles (78.5 ± 9 g). The indirect method was adopted for nutrient digestibility estimate. Chromium oxide (0.5%) was added to the diet as marker, and feces were collected by sedimentation every four hours. Among all tested ingredients, corn gluten meal showed the highest apparent digestibility coefficients (95.0% of protein, 88.0% of energy […]

The coefficient of apparent digestibility (CAD) of four dry extruded dog foods was compared, each one formulated with a different protein source: soybean meal (SM), corn gluten meal (GM), meat and bone meal (MBM) and poultry meal (PM). A completely randomized design was used, with four treatments (protein source) and six repetitions per treatment, in a total of 24 animals. Tukey test was used to compare treatments means. The diet based on GM showed the highest CAD of crude protein […]

The objective of this trial was to determine the energy value of oat, barley, cassava residue and linseed grain (whole and milled) for Japanese quails (Coturnix coturnix japonica). Three hundred and sixty 40-d male quails were assigned to a completely randomized design with six treatments (reference diet + five feedstuffs), six replications and ten birds per pen. The total feces collection was the used methodology. The feedstuffs evaluated were used at a level of 20% replacing the energy source of […]

Two experiments were carried out to determine nutritive value and verify performance of growing and finishing swine feed high moisture corn silage (HMCS) and reconstituted silage (RS) of higher oil corn. The digestibility assay was carried twelve cross breed barrow, were allotted in metabolism cages, in a completely randomized design. The values of digestible dry matter (DDM), digestible protein (DP), digestible starch (DS), digestible ether extract (DEE), digestible organic matter (DOM), digestible energy (DE) and metabolizable energy (ME) were for […]

This experiment was conducted to evaluate the effect of multienzymatic complex (MC) addition in diets with different types of extruded soybeans on the energy values and nutrient digestibility coefficients for broiler chicks. A total of 288 Avian Farms males broiler chicks averaging eight days old was allotted to a 3 x 2 factorial arrangement (under, standard and over processed extruded full fat soybean-based diets with and without MC, in a total of six treatments with eight replicates and six birds […]

Two experiments were carried out to determine the nutritive value and to evaluate the performance of growing rabbits fed on isoenergetic diets containing high moisture sorghum silage grain with low or high tannin levels. In the digestibility assay (experiment 1), the nutritive values of silages were determined with 30 New Zealand White rabbits, 15 males and 15 females, 55 days old, allotted in a completely randomized design, with 3 treatments and 10 replications. In each treatment the each sorghum silage […]

This trial was conducted to investigate the replacement of soybean meal with a mixture of urea plus cassava scrapings on nutrient intake, digestibility, and production of crossbred lactating cows fed diets containing forage cactus (Opuntia ficus indica, Mill), sorghum silage, and concentrate. Eight crossbred holstein:zebu cows averaging 60±30 days in milk and initial body weight (BW) of 491 kg were randomly assigned to two replicated 4 × 4 Latin squares and were fed diets with increasing levels of urea plus […]

The experiment was conducted with the objective of evaluating chemical composition and in vitro dry matter digestibility of sugar-cane bagasse containing 60% dry matter submited to increasing sodium hydroxide concentrations (0, 2.5, 5, and 7.5% NaOH on a dry matter basis). NaOH was applied as a 2:1 water:NaOH solution, over different treatment times (1, 3, 5, and 7 days). Plastic pails with 10 L capacity were utilized and stocked in climatic chamber at 25ºC constant temperature. The experimental treatments had […]

This study was conducted to evaluate replacement of ground corn grain with cassava scrapings on nutrient intake, digestibility, and production of primiparous Holstein lactating dairy cows receivind diets containing forage cactus (Opuntia ficus indica, Mill), sorghum silage and concentrate. Five cows averaging 60±15 of days in milk and initial body weight (BW) of 448 kg were randomly assigned to a 5 × 5 Latin square with increasing levels of cassava scrapings in the diet: 0, 25, 50, 75 or 100%.
