| ABSTRACT This work aimed to evaluate the performance and egg quality of lightweight laying hens supplemented with a high biological value mineral, carbo-amino-phospho-chelates (CAPC), compared with inorganic minerals (sulfates), at different recommended values. A total of 320 Dekalb White hens, between 53 and 77 weeks of age, were distributed in a completely randomized design into two treatments, 10 replicates of 16 birds each. The treatments consisted of a reference diet formulated according to breed manual recommendations, in which one group was supplemented with a trace mineral source, CAPC (Cu, 8.6; Fe, 43.7; Mn, 56.4; Se, 0.34; and Zn, 43.7 mg/kg) and the other with a sulfate source, using the levels recommended in the breed manual (Cu, 8; Fe, 60; Mn,... |

| O objetivo deste trabalho foi avaliar o efeito da adição do prebiótico mananoligossacarídeo (MOS) nas dietas de leitões sobre a digestibilidade dos nutrientes, o desempenho e as características morfofisiológicas do trato digestório. No primeiro experimento, foram utilizados 16 leitões com peso de 24,8±2,79 kg. Utilizou-se o método de coleta total de fezes para determinar a digestibilidade das rações controle e com 0,5% de prebiótico. No segundo experimento, avaliaram-se o desempenho e a incidência de diarreia em 30 leitoas com idade entre 22 e 63 dias e peso inicial de 6,28±1,40 kg. No terceiro experimento, foram avaliados a morfometria intestinal, os pesos relativos do fígado e do pâncreas e o pH dos conteúdos do estômago, intestino delgado e ceco em 15... |

| The aim of this work was to study the effect of inclusion of citrus pulp in the diet of finishing pigs. In the first trial, 16 Topigs barrows with 80.5±4.7 kg of initial BW were used to evaluate the digestibility of citrus pulp. Having 18.85% of neutral detergent fiber and 41.18% of neutral detergent soluble fiber, citrus pulp showed as a feasible alternative ingredient to be added in the diets of feed restricted finishing pigs. Second trial tested the use of 0, 10, 20, 30% of citrus pulp in the diets of 36-feed-restricted barrows with initial BW of 83.7±5.1 kg. A quadratic trend (P<0.05) as function of citrus pulp levels was observed for daily weight gain and number of experimental days to reach 130kg BW, being the best estimated inclusion levels of... |

| The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block design consisting of four experimental diets, six repetitions and 12 piglets per experimental unit was adopted. The pre-starter I (7 to 21 days), pre-starter II (22 to 35 days) and starter I (36 to 49 days) diets were supplemented as follows: control diet (CD): no plasma or yeast extract; plasma (PL) diet: addition of 6%, 4% and 2% plasma; yeast extract (YE) diet: addition of 6%, 4% and 2% yeast extract;... |

| ABSTRACT This research aimed to evaluate enzyme supplementation in diets with different nutritional levels for pigs in their feces excretion and anaerobic digestion. Fifty four gilts were placed on diets formulated to achieve 100 or 95 or 90 % of a pig's nutrient requirements, with the addition of an enzyme complex containing amylase, β-glucanase, cellulase, pectinase, xylanase, protease and phytase (diets 100E, 95E and 90E) or without the enzymes (diets 100, 95 and 90). The trial was divided into three periods (1, 1-2 and 1-3) based on the animal weight. The enzyme complex reduced (p < 0.05) excretions per period and per unit of weight gain (residue coefficients) of organic matter (OM) in Period 1, of N, Ca, Zn and Na in Period 1-2, and of Na... |

| Foram avaliados os efeitos da inclusão do farelo de trigo (FT) com e sem a suplementação da ração com um complexo enzimático (CE), composto de amilase, protease e celulase, sobre o desempenho de frangas semipesadas (15 semanas de idade) e seu efeito residual na produção de ovos. Foram utilizadas 288 frangas, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 4X2, sendo quatro níveis de FT e dois níveis de um CE na ração: 0 (controle), 10, 20 e 30% X suplementação com 0 ou 50g de um CE/100 kg de ração, resultando em oito tratamentos, com seis repetições. Na fase de crescimento, o consumo de ração, o ganho de peso, a conversão alimentar e o peso vivo foram melhores para as aves que receberam as dietas isentas de FT. A adição do CE... |

| This experiment was carried out to evaluate the effects of purified cellulose, soybean hulls and citrus pulp in the diet of weaned piglets. A total of 72 piglets (36 castrated males and 36 females) weaned at 21 days of age (BW 6.45±0.66 kg) was distributed according to a randomized block design, for evaluation of performance, transit time, diarrhea incidence and blood parameters of piglets which received diets containing different sources of fiber. The experimental diets were: control diet - diet composed of corn, soybean meal and a source of lactose; control + 1.5% purified cellulose; control + 3% soybean hull and control + 9% citrus pulp. The inclusion of purified cellulose, soybean hulls and citrus pulp in diets of weaned piglets did not affect the... |

| Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus... |
