“…O uso de alimentos que substituam o milho e/ou a soja nas rações é uma boa alternativa. O farelo de girassol é um subproduto que pode ser utilizado como alternativa na substituição ao farelo de soja em rações para frangos de corte, entretanto, apresenta baixo nível de lisina, elevado teor de fibra e baixo valor de energia metabolizável (Senkoylu & Dale, 1999), fatores que podem limitar sua inclusão em rações para aves.

RESUMO -Foi realizado um experimento para avaliar os efeitos da inclusão de farelo de girassol em rações para frangos de corte sobre o desempenho, o rendimento de carcaça e dos cortes e a viabilidade econômica. O delineamento experimental foi em blocos casualizados com cinco níveis de farelo de girassol (0, 5, 10, 15 e 20% da dieta basal), oito repetições e 20 aves por unidade experimental. As aves e as rações foram pesadas no início e ao final de cada fase do período experimental(1 a 21 dias e 22 a 42 dias) para obtenção do consumo de ração, do ganho de peso e da conversão alimentar. Duas aves de cada repetição foram abatidas aos 42 dias de idade para avaliação da carcaça. Com a inclusão do farelo de girassol, o consumo diminuiu linearmente na fase inicial (y = 1185,1 -2,1x; R 2 = 0,97), enquanto a conversão alimentar melhorou de forma linear no período total (y = 1,6404 -0,0018x; R 2 = 0,62) e de forma quadrática na fase inicial (y = 1,3943 -0,0069x + 0,0002x 2 ; R 2 = 0,96). Não foi encontrada diferença significativa no rendimento de carcaça e dos cortes. Os melhores desempenhos econômicos foram obtidos quando as aves foram alimentadas com rações contendo 5% de farelo de girassol na fase inicial e 0% na fase de crescimento e no período total. A adição de 20% de farelo de girassol em rações para frangos de corte até os 42 dias de idade não prejudica o desempenho produtivo das aves.

A randomized block experimental design was used, with five treatments and eight replications of 20 birds per experimental unit. Treatments consisted of including 0, 5, 10, 15, or 20% sunflower meal in a basal diet. Birds and diets were weighed at the beginning and at the end of each experimental phase (1 to 21 days and 22 to 42 days) to determine feed intake, weight gain, and the feed:gain ratio. Two birds per replication were slaughtered at 42 days of age for carcass evaluation. Feed intake was linearly reduced in the starter phase (y = 1185.1 -2.1x; R 2 = 0.97), with sunflower meal inclusion in the basal diet, and the feed:gain ratio linearly improved in the total period (y = 1.6404 -0.0018x; R 2 = 0.62), whereas a quadratic effect on the feed:gain ratio was observed in the starter phase (y = 1.3943 -0.0069x + 0.0002x 2 ; R 2 = 0.96). No significant differences were observed for carcass yield and cuts. The best economic performances were achieved when the birds were fed diets containing 5% sunflower meal in the starter phase, and 0% in the grower phase and total period. The inclusion of 20% sunflower meal in the diet of broilers up to 42 days of age did not show harmful effects on performance.Key Words: alternative feedstuffs, carcass, poultry production IntroduçãoNutricionistas têm buscado alternativas que t...

“…The chemical composition of sunflower depends on the weather, variety, soil and how crops are grown (Karunajeewa et al, 1989;Senkoylu & Dale, 1999). In this context, great variation in the chemical composition of sunflower meal has been observed due to the method for oil processing and extraction (Karunajeewa et al, 1989;Vieira et al, 1992).…”

The objective of this trial was to evaluate the effect of sunflower seed inclusion (0, 1.4, 2.8, 4.2 and 5.6%) in a laying hen diet containing corn, soybean meal, wheat meal and soybean oil as main ingredients on performance and egg quality. The evaluated variables were daily feed intake, average egg weight, feed conversion (kg.kg -1 and kg.dz -1), eggshell percentage, yolk color and Haugh unit. One hundred and sixty 25 weekold Lohmann laying hens were used in a completely randomized design with five treatments and four replications of eight birds per experimental unit. Four periods of 28 days were evaluated during 112 days. The inclusion of sunflower seed in the diet had no effect on production parameters during the experimental period. Thus, can be concluded that sunflower seed might be used at concentrations up to 5.6% in laying hen diets without affecting performance and egg quality.

“…Sunflower seed meal (SFSM) is a major potential feed ingredient in many countries (Senkoylu and Dale, 1999). Together with cotton seed meal and canola meal, SFSM is frequently used as an alternative to soybean meal (Rose et al, 1972;Leeson et al, 1987;Barros et al, 2002).…”

The experiment was conducted to determine the chemical composition, digestible energy (DE), metabolisable energy (ME) and the apparent total tract digestibility (ATTD) in sunflower seed meal (SFSM) and to develop reasonable prediction equations for estimating energy digestibility based on chemical composition of these meals for growing pigs. Ten SFSMs were collected and 66 crossbred barrows (initial body weight=36.43±5.25 kg) were randomly allocated to one of eleven diets. The basal diet was based on corn and soybean meal which contained 82.2% corn, 14.8% de-hulled soybean meal and 3% premix. The test diets contained 30% SFSM at the expense of corn and soybean meals. The experiment comprised a 7-d adaptation period followed by a 5-d collection period of faecal matter and urine. On a dry matter (DM) basis, the content of crude protein, neutral and acid detergent fibre, and gross energy (GE) ranged from 29.33 to 39.09%, 38.15 to 55.40%, 24.59 to 37.34% and 18.65 to 21.50 MJ/kg, respectively. The concentration of DE and ME ranged from 10.51 to 12.47 MJ/kg and 10.26 to 12.16 MJ/kg of DM, respectively. The DE values and ATTD of GE among the ten SFSMs significantly differed (P<0.05). The ATTD of GE ranged from 52.86 to 63.90%. The best models for predicting DE and ME were also established. In conclusion, the chemical composition of SFSM was variable (coeffiecient of variance>10%) among the ten SFSMs (DM). The results of DE, ME and prediction equations could be applied to evaluate the energy digestibility of SFSM in growing pigs.
