ABSTRACT The objective of this study was to evaluate increasing levels of dried apple pomace on cat diets and its effects on the apparent total tract digestibility (ATTD) of nutrients and diet metabolizable energy (ME) and palatability. Fecal characteristics of cats were also evaluated. Four experimental diets were produced to contain 0, 30, 60, and 90 g kg−1 of dried apple pomace. Two experiments were carried out. In experiment 1, the diets were offered to twelve adult cats distributed in […]

The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The treatments were established according to material used as substrate for broiler litter: treatment 1 – rice husks; 2 – sugar cane bagasse; 3 – wood shavings; 4 – wood shavings + sugar cane bagasse; 5 – rice husks + sugar cane bagasse; and 6 – Napier […]

The objective of this study was to evaluate the effects of supplementation with different sources of energy and nitrogenous compounds on the in vitro growth and production of bacteriocin of lactic acid bacteria. Incubations were performed by using ruminal fluid from a rumen-fistulated Holstein-Zebu steer. The animal was kept on a Brachiaria decumbens pasture receiving 200 g/day of supplemental crude protein. Substrates and inoculum were placed in glass flasks considering eight treatments: cellulose, cellulose and casein, cellulose and soy peptone, […]

The chemical composition and in vitro dry matter digestibility (IVDMD) of corn and sorghum silages with and without microbial inoculants after several fermentation periods were evaluated in laboratory silos. A 6 x 2 x 3 factorial treatment combination (6 fermentation periods x 2 silages x 3 inoculants) was assayed in a completely randomized design to evaluate the dry matter (DM) and crude protein (CP) contents and a 4 x 2 x 3 factorial arrangement of treatments (4 fermentation periods x […]

The forage digestion characteristics can better be understood when associated with studies of tissue anatomy of forage species. Aiming at new focus to this issue, the area of several tissues present in leaves and stems of B. brizantha and B. humidicola, were determined at three different regions of the plant. The assay was carried out at greenhouse, with plants growing in pots with sterilized sand, receiving nutritive solution of macro and micronutrients. After 70 days of growing period, the segment […]

This work aimed to evaluate different crude fiber levels on reverted Nile tilapia (Oreochromis niloticus, L) fingerlings performance and time of retention of food. One hundred and twenty-five fingerlings of Thai strain, 1.39 ± 0.03 g of initial weight were allotted to twenty-five 54 L aquarium, at five treatments and five replications on completely randomized design. Five isoenergy (3000 kcal/kg of digestible energy) and isoprotein (30% of crude protein) diets were formulated with five different crude fiber levels (3.65, 4.75, […]

This study aimed to evaluate the ammoniation effect on the crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM), cellulose (CEL) and lignin (LIG) levels and the in vitro organic matter digestibility (IVOMD) coefficient of urea-ammonia treated (4%; dry matter basis) Annonigrass 2 (Eragrostis plana Nees) hay, at five cutting ages (30, 60, 90, 120, 150 days). A randomized complete block design was used, with four replicates in a factorial arrangement (2×5), with two factors: hay […]

This work was carried out to evaluate the cutting effect at 0, 15, 30 and 45 cm height, on the chemical composition of elephant grass (Pennisetum purpureum, Schum.) cv. Roxo in dry and rainy seasons. The samples were obtained from an useful area of 8,4 m2 from each parcel. After the uniformity cut two cuts in dry season with 90 days interval, and three cuts in rainy seasons with 60 days interval. A sample of 3 or 5 tillers was […]

This assay was conducted with sheep to evaluate in vivo digestibility of the dry matter and fiber fraction of broiler litters based on wood scraps, elephant grass Napier, corncob with husks and the aerial part of cassava. A completely randomized blocks experimental design with four treatments and five blocks with four sheep, considering the live weight of the animals, were used. Twenty Morada Nova sheep, white variety, with 18 months of age and live weight from 17.2 to 27.3 kg […]
