It was studied five management systems of native pasture, under grazing, from Rio Grande do Sul State: with biennial burning for more than 100 years, without burning for 32 years with or without mowing, and pasture improvement for 7 and 24 years. The forage accumulation and the senescent material detached from the plant, were evaluated using grazing exclusion cage. The experimental design was a completely randomized with three replications. The systems without burning were more productive and among these the […]

This experiment was carried out in a greenhouse condition to study the effect of phosphorus, arbuscular mycorrhizal fungi and nitrogen on mineral accumulation in braquiaria MG-4 (Brachiaria brizantha cv. MG-4) above ground forage DM and peanut (Arachis pintoi cv. Amarillo) mixture, in soil of low fertility. The experimental design was a completely randomized in a 5x2x2 factorial arrangement, with five P rates (25, 50, 75, 100 and 200 mg/kg of soil), two inoculations (inoculated and no inoculated) and two levels […]

This work was carried out to evaluate the ruminal degradation of dry matter, crude protein and neutral detergent fiber and ruminal particles and liquid phase dynamics by steers in natural pasture of the Zona da Mata, region of Minas Gerais State, during different seasons of the year. The season 1(S1) corresponded to the months of February/March/April, and the season 2(S2), to the months of August/September/October. Five steers with esophageal and rumen fistulae, each one considered as a replicate, were used […]

This trial was conducted at National Beef Cattle Research Center of Brazilian Agricultural Research Corporation (Embrapa Beef Cattle), to evaluate the morphogenetic characteristics of leaves and tiller, green dry matter yield and growth index of Tanzaniagrass in two post-graze stubbles (high post-graze stubble (HPS) ¾

Aiming to evaluate different inclusion levels of cassava meal (0.00, 6.00, 12.00, 18.00 and 24.00%) in diets with 30.00% of digestible protein and 3,000 kcal/kg of digestible energy to Nile tilapia fingerlings, an experiment was carried out at the Aquaculture Laboratory /DBI/UEM. Two hundred reverted Thai strain Nile tilapia fingerlings were utilized, with an initial weight of 0.84 g and 35 days old, distributed in 25 250L tanks, in a completely randomized design with five treatments and five replications. Averages […]

It were utilized four crossbreed, castrated, rumen cannuladed bovines, receiving dietary starea (containing 30% of urea) in the concentrate and corn silage, with the objective of quantify the liquid-associated bacteria and protozoa, solid-associated bacteria and related them with the ruminal pH. Three samples from ruminal content were harvested at 1 a.m., 2 a.m. and 30 min and 11 a.m. and 30 min after feeding. The microbial mass was quantified and qualified in the different fractions of solid-associated bacteria (SAB), liquid-associated […]

Weight, height at withers and the weight/height ratio (an indicator of body condition) of respectively, 263, 232 and 232 cows and 171, 135 and 135 heifers were studied. Animals were of six red and white Holstein-Friesian (HF) x Guzerá (Guz) crosses: ¼, ½, 5/8, ¾, 7/8 and ³ 31/32 HF. Model [1] for cows included the fixed effects of reproductive status, days in milk, season when weighted, farm class, age and genetic group, two-factor interactions and the random effect of […]

Eighty piglets, half weaned at 20 days of age and half weaned at 25 daysof age, weighing 4.55 ± 0.67 and 6.62 kg ± 0.92 kg, respectively, were allotted to an experimental randomized block design in a factorial scheme, with five replicates of four animals per experimental unit, to evaluate two diets and two weaning periods and its effects in the growing and finishing phases. Different characteristics of diets were obtained with inclusion levels of ingredients: dried skin milk, sugar […]

Four hundred and fifty quails of each sex, in a total of nine hundred quails, were assigned to a completely randomized design with five replicates of six quails per experimental unit, to estimate the crude protein (CP) and metabolizable energy (ME) requirements for maximum performance of females and males Japanese quails reared for meat production purpose and to determine the best slaughter age. The treatments were consisted of the quails sex and the experimental diets, resultant from the combination of […]

The influence of the substitution of soybean meal protein (SM) by canola meal protein (CM) in Prochilodus lineatus fingerling diets was verified. One hundred and twenty specimens, averaging weight 1.88±0.82g and total length 5.40±0.99cm, was assigned to a completely randomized randomized design, with six treatments and four replicates, in a 50 L glass aquarium, with five fingerlings in each experimental unit. Isoprotein (26.00%), isocalcium (0.90%) and isophosphorus (0.70%) diets were formulated with increasing replacement levels of SM protein by CM […]
