“…The performance of the birds could be affected in the treatments with the addition of tannin due to the factors mentioned by Silva et al (2009). a decrease in palatability of food and voluntary intake, a reduction in the digestibility of protein, carbohydrates, starch and lipids, and mainly an inhibition of some enzymes present in the digestive tract.…”

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

“…Among the commercially available energy ingredients, low-tannin sorghum stands out for having nutritional characteristics similar to corn, with high anti-oxidant effect (Silva et al, 2009), market availability, and affordable price, which could minimize the production costs affected by the price variation of supplies (May et al, 2011).…”

-The objective of this work was to evaluate the reproductive performance of silver catfish (Rhamdia quelen) fed diets containing sorghum, as a replacement for corn, supplemented or not with phytase. The experiment was carried out with 360 fish, with 16.02±0.58 g mean initial weight, fed diets in which low-tannin sorghum replaced corn at 0, 50, and 100%, with or without phytase supplementation (1,500 FTU per kilogram of feed). Diets supplemented with phytase or with 100% sorghum led to a reduction of visceral fat deposition and hepatic mass in males. In females, similar results were observed for diets containing phytase. Females fed sorghum-only diets, supplemented or not with phytase, had bigger oocytes. Males and females at the developing and final stages of gonadal maturation were found in all treatments. The replacement of corn by sorghum affects neither semen quality nor the fertilization rate of gametes. Therefore, complete replacement of corn with low-tannin sorghum in the diet can be performed without compromising the reproductive performance or the somatic indexes of silver catfish.Index terms: Rhamdia quelen, alternative food, breeding nutrition, histology, quality of gametes. Desempenho reprodutivo de jundiá alimentado com dietas com sorgo suplementadas com fitaseResumo -O objetivo deste trabalho foi avaliar o desempenho reprodutivo de jundiá (Rhamdia quelen) alimentado com dietas contendo sorgo em substituição ao milho, suplementadas ou não com fitase. O experimento foi realizado com 360 jundiás, com peso médio inicial de 16,02±0,58 g, alimentados com dietas compostas por 0, 50 e 100% de sorgo de baixo tanino, em substituição ao milho, com ou sem a suplementação de fitase (1.500 UFA por quilograma da dieta). Dietas com suplementação de fitase ou com 100% de sorgo reduziram a deposição de gordura visceral e a massa hepática nos machos. Nas fêmeas, o mesmo efeito foi observado quanto às dietas com suplementação de fitase. As fêmeas alimentadas com dietas apenas com sorgo, suplementadas ou não com fitase, apresentaram ovócitos maiores. Foram encontrados machos e fêmeas nas fases finais de desenvolvimento e maturação gonadal, em todos os tratamentos. A substituição do milho pelo sorgo não afeta a qualidade seminal nem a taxa de fertilização dos gametas. Portanto, a substituição completa do milho pelo sorgo de baixo tanino pode ser efetuada sem afetar os parâmetros reprodutivos e os índices somáticos do jundiá.Termos para indexação: Rhamdia quelen, alimento alternativo, nutrição de reprodutores, histologia, qualidade de gametas.

“…Os autores Silva (2003); Garcia et al (2005) No presente trabalho podemos notar resultados satisfatórios de rendimentos com a inclusão de sorgo na alimentação das codornas. Em relação a rendimentos para aves alimentadas com sorgo, a literatura só se refere a frangos de corte.…”

This study aimed to compare four levels of ground grain sorghum as an energy source in the diet of Japanese quails to court, evaluating the growth performance, carcass yield and cuts and the chemical composition of some cuts. In total, 1200 Japanese quail (Coturnix coturnix japonica), females with a day old, were distributed according to a completely randomized design consisting of four treatments and six replicates each, as follows: 0%, 40%, 60%, sorghum 100% in the two phases (start, a growth 21 days and from 22 to 42 days of age). The variables analyzed were weight gain; feed conversion; mortality; eviscerated carcass yield and cuts (full chest-, thighs / drumsticks); chemical composition of breast and drumstick / thigh. The performance variables were submitted to the Anderson-Darling test and the nonparametric Kruskal-Wallis. Variables yield and carcass composition were subjected to the Anderson-Darling test and the means were compared by Tukey test and Scott-Knott. There were no significant differences in performance variables, yield and composition of cuts. We conclude sorghum can be used as an ingredient in the nutrition of Japanese quail to cut without sacrificing performance (feed conversion, weight gain and mortality) as well as the yield of cuts (drumstick / thigh and breast) and housing and also qualitative characteristics of the cuts (drumstick / thigh and chest).
