Neutral detergent fibre in piglet diets: digestibility, performance, and deposition of body nutrients

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT A total 120 piglets with an average live weight of 7.00 kg, weaned at 21 days, were used to evaluate the effect of neutral detergent fibre levels on the digestibility of nutrients and energy from the diets, productive performance, and the composition and rate of deposition of nutrients and energ...

Replacing soybean oil with increasing levels of soybean acid oil in diets of coturnix quails (Coturnix coturnix coturnix) and the effects on egg quality

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8%) as a replacer for soybean oil and eight replicates of two qua...

Quantification of anti-nutritional factors and their correlations with protein and oil in soybeans

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Soybeans contain about 30% carbohydrate, mainly consisting of non-starch polysaccharides (NSP) and oligosaccharides. NSP are not hydrolyzed in the gastrointestinal tract of monogastric animals. These NSP negatively affect the development of these animals, especially the soluble fraction. This wo...

Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incid...

Apparent digestibility of conventional and alternative feedstuffs by hybrid tambacu juveniles

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT The apparent digestibility coefficients (ADC's) of dry matter (DM), crude protein (CP), and gross energy (GE) of conventional feedstuffs (cottonseed meal-CSM, soybean meal-SBM, wheat bran-WHB, corn-COR) and regional alternative feedstuffs (common bean residue meal-CBR, mesquite meal-MES, pasta b...

Action time and feed frequency of Lactobacillus plantarum for Nile tilapia

O objetivo desta pesquisa foi avaliar o tempo de ação do Lactobacillus plantarum no trato intestinal, assim como em qual frequência esse probiótico deve ser oferecido para tilápia-do-nilo (Oreochomis niloticus). Quarenta e oito tilápias foram alimentadas com ou sem probiótico, durante 14 dias. Ap�...

Concentrado proteico de arroz na alimentação do jundiá (Rhamdia quelen)

O objetivo do presente trabalho foi avaliar a inclusão do concentrado proteico da destilação de etanol obtido de arroz (CPA) na alimentação do jundiá. Trezentos e setenta e cinco peixes foram distribuídos em sistema de recirculação de água com 15 caixas (125L). Foram testadas três dietas (37% ...

Mobilization of energetic substrates in the endangered catfish Steindachneridion parahybae (Siluriformes: Pimelodidae): changes in annual reproductive cycle in captivity

Neotrop. ichthyol; 16 (2), 2018
This study aimed at analyzing the energetic substrate (ES) in the main storage tissues of Steindachneridion parahybae, throughout the reproductive cycle in captivity. Differently from wild, in captivity, feeding is not interrupted during the reproductive period, the females do not spawn spontaneously, an...

Forage potential of native ecotypes of Paspalum notatum and P. guenoarum

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The Paspalum genus includes several species that are important for livestock in Rio Grande do Sul, such as P. notatum and P. guenoarum, typical of native pastures of the Pampa biome. The aim of this study was to investigate forage production and chemical composition of four ecotypes of these spe...

Fatty acid profile in vertical strata of elephant grass subjected to intermittent stocking

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate cl...
