“…The lack of effect on feed intake of birds fed diet with soybean hulls and coffee husks in comparison with those fed diet containing wheat bran indicates that the changes caused by the composition of such fiber sources in the viscosity of gastrointestinal contents probably were not significant enough to compromise feed intake. Those results agree with Araujo et al (2008), who observed that the inclusion of up to 9% wheat bran in the feed did not interfere with its intake. According to the authors, the physiological maturity of the gastrointestinal tract of animals is an important factor to be observed in adjusting the levels of alternative feeds in diets to digestive capacity of layers, especially the low digestibility of the nutrients in these feeds.…”

The objective of this study was to ascertain the influence of different dietary fiber sources and the usage of xylanase on diet of commercial layers and their influence on productive performance, egg quality, and digestive organ biometry. A total of 864 Lohmann ® White hens was fed diets with three different fiber sources (wheat bran, soybean hull, or coffee husk) with or without xylanase inclusion (concentration of 160,000 BXU/g) in a 3×2 factorial arrangement, with six replicates of 24 birds each, from 25 to 44 weeks of age. There were no interactions between dietary fiber and xylanase inclusion. The enzyme supplementation did not influence any parameters evaluated. There were dietary fiber effects on body weight gain, viability, egg weight, eggshell quality, yolk pigmentation, and liver and gizzard relative weights. Wheat bran, soybean hull, and coffee husk can be used in laying hen diets without detrimental effect on productive performance. The enzyme used had no effect on the performance and eggshell quality of laying hens.

et al. 2014

The effect of cholecalciferol (D 3 ) and 25-hydroxycholecalciferol (25-OHD 3 ) as isolated or associated sources of vitamin D (100%-0%, 75%-25%, 50%-50%, 25%-75%, 0%-100%) on the productive performance, egg quality, and bone characteristics was evaluated in white egg-laying hens fed two levels of calcium (Ca) and phosphorus (P) in the basal diet (BD) (BD1 = 0.38% Ca -0.36% available P and BD2 = 3.2% Ca -0.30% available P). Nine hundred and sixty Dekalb White hens (24 weeks old) were distributed into 80 cages, under a completely randomized factorial design for 16 weeks. The use of associated sources of vitamin D reduced the feed intake and feed conversion ratio, as well as BD1, which also increased the egg production and egg mass. The association of vitamin D sources with up to 50% 25-OHD 3 increased the eggshell percentage. There was interaction (p<0.05) between the sources of vitamin D and the concentrations of Ca and available P, sources with at least 50% 25-OHD 3 increased ash percentage and bone radiographic densitometry (BRD) with BD1; in BD2 the use of 25-OHD 3 as isolated vitamin D source increased BRD. The association of D 3 and 25-OHD 3 improved the productive performance, increased the percentage of eggshell and had different positive effects on the bone characteristics that depend on the concentrations of Ca and available P in the balanced feed of white egg-laying hens.Index terms: Vitamin sources, productive performance, eggshell quality, bone characteristics. RESUMOO objetivo desta pesquisa foi avaliar o efeito da suplementação de colecalciferol (D 3 ) e 25 hidroxicolecalciferol (25-OHD 3 ) como fontes isoladas ou associadas (100%-0%; 75%-25%; 50%-50%; 25%-75%; 0%-100%) de vitamina D sobre o desempenho, a qualidade de casca e as características ósseas, em galinhas poedeiras de ovos brancos de 24 semanas de idade alimentadas com duas concentrações de cálcio (Ca) e fósforo disponível (Pdisp) na dieta basal (DB) (DB1 = 0,38% Ca -0,36% Pdisp e DB2= 3,2% Ca -0,30 % Pdisp), durante um período experimental de 16 semanas. Foram utilizadas 960 galinhas Dekalb White em delineamento inteiramente casualizado, com oito repetições e doze aves por unidade experimental. Os tratamentos foram constituídos de um fatorial (5x2), associações de vitamina D e concentrações de Ca e Pdisp. As fontes de vitamina D associadase a maior concentração de Ca e Pdisp diminuíram o consumo de ração e a conversão alimentar. Além disso, a maior concentração de Ca e Pdisp incrementou a produção e massa de ovo. A suplementação a partir de 50% de 25-OHD 3 entre as associações de vitamina D aumentou a porcentagem de casca do ovo. Houve interação entre as fontes de vitamina D e as concentrações de Ca e Pdisp. As fontes de vitamina D na DB1 com pelo menos 50% de 25-OHD 3 incrementaram a porcentagem de cinzas e a densitometria óssea radiográfica (BRD). A suplementação de 25-OHD 3 na DB2 como fonte isolada de vitamina D aumentou a BRD.Termos para indexação: Fontes de vitamina, desempenho produtivo, qualidade de casca, caraterísticas ós...

ABSTRACT. This study aimed to evaluate the inclusion of Brazil nut oil in diets for breeder cocks on performance, semen analyses, biochemical serum profile and testicular morphology. Forty-two Rhode Island Red breeder cocks with 40 weeks of age were used. The experimental design was completely randomized consisting of seven levels of Brazil nut oil (0; 0.30; 0.60; 0.90; 1.20; 1.50 and 1.80%) in the diets. Data collected were evaluated by polynomial regression. Differences (p < 0.05) were detected in feed conversion, semen volume, motility, vigor, pH, swirling and concentration, in which the inclusion of Brazil nut oil in the diets improved the reproductive performance. Differences (p < 0.05) were also detected in the biochemical serum profile (triglycerides, cholesterol and blood pH); the inclusion of Brazil nut oil caused a large increase in blood triglycerides and cholesterol levels, consequently, changing the blood pH. The Brazil nut oil can be used as an energetic additive in diets given to breeder cocks, promoting better reproductive performance, without changing semen and testicular morphology, but altering the biochemical serum profile of the birds.Keywords: additive, fatty acids, metabolism, reproductive performance. Óleo de castanha do Brasil em rações de galos reprodutoresRESUMO. Objetivou-se avaliar a inclusão de níveis crescentes de óleo de castanha do Brasil (0; 0,30; 0,60; 0,90; 1,20; 1,50 e 1,80%) em rações de galos reprodutores sobre o desempenho, análise andrológica, perfil bioquímico sérico e biometria testicular. Foram utilizados 42 galos reprodutores Rhode Island Red com 40 semanas, distribuídos em um delineamento experimental inteiramente casualizado constituído de sete tratamentos com seis galos (repetições) cada. As estimativas dos níveis de óleo de castanha foram determinadas através de regressão polinomial à 5% de significância. Foram observadas diferenças (p < 0,05) nos resultados de conversão alimentar, volume seminal, motilidade, vigor, pH turbilhonamento e concentração seminal a partir da a inclusão de óleo de castanha do Brasil nas rações. Os resultados de perfil bioquímico sérico (triglicerídeos, colesterol e pH sanguíneo) também apresentaram diferenças (p < 0,05) onde a inclusão de óleo de castanha do Brasil nas rações ocasionou maior acúmulo de triglicerídeos e colesterol sanguíneo, consequentemente modificando o pH do meio. Concluiu-se que o óleo de castanha do Brasil pode ser utilizado como aditivo energético em rações para galos reprodutores promovendo melhora na conversão alimentar e no desempenho reprodutivo, sem modificar a morfologia espermática e testicular, porém, alterando o perfil bioquímico sérico das aves.Palavras-chave: ácidos graxos, aditivo, desempenho reprodutivo, metabolismo.
