“…Porém, o principal fator limitante da sua utilização na alimentação de animais monogástricos é o alto teor de fibras (JACOB et al, 1996), que diminui a energia metabolizável das rações e o aproveitamento dos nutrientes (WARPECHOWSKI, 2005;SENKOYLU;DALE, 2006).…”

ResumoForam realizados dois experimentos para avaliar o uso da torta de girassol (TG) na alimentação de frangos de corte, sendo determinado o seu valor nutricional e seus efeitos sobre o desempenho zootécnico. No primeiro experimento, de digestibilidade, foram utilizados 96 frangos de corte com 28 dias de idade, alimentados com uma ração referência e uma ração teste com inclusão de 20% de TG. Os valores dos coeficientes de digestibilidade da MS, PB, EE, FB e EMAn foram, com base na matéria natural, 46,18; 60,70; 81,53 e 6,42% e 2.800 kcal/kg, respectivamente. No segundo experimento, de desempenho, no qual foram utilizados 420 frangos, submetidos a sete tratamentos, sendo uma ração testemunha (0% TG) e a combinação de três níveis de inclusão de TG na ração (6, 12 e 18%) e duas idades de início do seu fornecimento, 20 (Id.1) ou 34 (Id.2) dias, observou-se efeitos quadráticos para consumo de ração e ganho de peso (pontos de máximo: 9,6 e 12,3%, respectivamente) e linear decrescente para a conversão alimentar para Id.1. Para o fornecimento a partir da Id.2 os parâmetros de desempenho não foram afetados pelos níveis de TG. Considerando-se a conversão alimentar a TG pode compor 18% das rações dos frangos de corte, a partir dos 20 ou 34 dias de idade.

Night-six animals aging, 28 days were utilized in Experiment 1. The animals were fed on a reference ration and on a test ration containing 20% of SC. Values for digestibility coefficients of DM, CP, EE, CF and AMEn were, based on natural matter, 46.18; 60.70; 81.53; 6.42% and 2,800 kcal/kg, respectively. In experiment 2, performance, where 420 chickens were used, assigned to seven treatments, being a control diet (0% SC) and the combination of three levels of dietary inclusion of SC (6, 12 and 18%) and two ages starting at first feeding, 20 (A1) or 34 (A2) days, there was a quadratic effect on feed intake and weight gain (maximum points: 9.6 and 12.3% respectively) and linear decrease in feed conversion for A1. For the feeding at A2 the performance parameters were not affected by the levels of SC. Considering that feed conversion to SC can compose 18% of the diets of broilers from 20 or 34 days.

“…Replacing (30%) of soybean meal by sunflower meal in the diets did not have any detrimental effect on the productive performance of broilers [18]. A significant improvement (P <0.05) in the productive performance of broiler chickens when fed sunflower meal in the starter diets of broiler at rate of (28-30%) [35] . There was a possibility of using sunflower meal in the diets of laying hens by up to 12% without affected the productive performance of chickens [14].…”

“…Several previous studies have attempted to establish the optimal level of SFM inclusion in broiler diets (RAMA RAO et al, 2006;SENKOYLU;DALE, 2006;RAZA et al, 2009). Rama Rao et al (2006) found that replacing soybean meal with 67% SFM in starter diets and 100% replacement in finisher diets did not affect weight gain, however, feed efficiency was decreased.…”

“…The reported levels of SFM are variable and their effects on broiler performance are highly dependent on the chemical composition and energy value of the SFM used, as well as the age of the studied birds (SENKOYLU; DALE, 2006). However, the addition of commercial enzyme complexes to the diets containing SFM could improve the nutrient availability and metabolizable energy content by increasing the amount of nutrients accessible to digestive enzymes.…”

-This research aimed to evaluate the effects of different levels of sunflower meal (SFM) and the supplementation of a multienzyme complex in the initial diets of broilers on their performance, intestinal morphometry and carcass characteristics. In all, 1100 1-d-old male chicks were distributed in a completely randomized design with 2 x 5 factorial arrangement (with and without a multienzyme supplement and five levels of SFM inclusion -0, 4, 8, 12 and 16%), and five replications per experimental unit. The experimental diets were provided until the chickens were 21-d-old and thereafter all birds received the same diet up to 42 d, to evaluate the possible residual effects of treatments. The SFM inclusion impaired performance from 1 to 21 d of age and the animals that received SFM during the initial phase, failed to recover from the negative effects on performance parameters. The multienzyme supplement improved the intestinal morphometry and was more effective than non-supplemented diets on performance, independent of the SFM inclusion level. The carcass and cuts yield of the wings and leg were significantly affected by the multienzyme supplementation. In conclusion, the SFM inclusion impaired performance variables and intestinal morphometry without affecting carcass yield; however, the supplementation of an enzyme complex counteracted the negative performance and intestinal morphometry effects.Keywords: Alternative food.
