Substituição do farelo de soja pela torta de babaçu em rações para frangos de corte dos 22 aos 42 dias de idade

Abstract

ResumoO objetivo deste trabalho foi avaliar a viabilidade técnica e econômica da substituição parcial do farelo de soja pela torta de babaçu em rações para frangos de corte dos 22 aos 42 dias de idade. Foram utilizados 80 frangos Cobb 500 ® , distribuídos em delineamento inteiramente casualizado, com quatro tratamentos (0, 10, 20 e 30% de substituição do farelo de soja pela torta de babaçu) e cinco repetições de quatro aves. Foram avaliados o desempenho (ganho de peso, consumo de ração e conversão alimentar), rendimentos de carcaça e cortes, biometria dos órgãos, custo com alimentação por kg de frango produzido e margem bruta. Para verificar as relações de custo da substituição do farelo de soja pela torta de babaçu, foram estabelecidas inequações. Os níveis de substituição do farelo de soja pela torta de babaçu não influenciaram (P>0,05) nenhuma das características de desempenho, o que evidenciou a viabilidade técnica da substituição de até 30% do alimento. Da mesma forma, não houve efeito sobre os rendimentos de carcaça, cortes e biometria dos órgãos. O menor custo com alimentação por kg de frango produzido e a maior margem bruta foram obtidos com a utilização da ração contendo 0% de torta de babaçu. O aumento do nível de substituição do farelo de soja pela torta de babaçu, nas rações para frangos de corte dos 22 aos 42 dias de idade mostrou-se economicamente inviável, porém, as inequações elaboradas podem ser de grande utilidade em situações práticas.

Licuri Bagasse (Syagrus Coronata) in Rations for Broilers

“…These results differ from those found by Silva et al (2015), by replacing soybean meal with babassu bagasse in rations for broilers from 22 to 42 days of age. They did not observe differences between treatments levels.…”

“…Possibly these results occurred due to the absence of essential amino acids in the coconut bagasse, which is not the case with the licuri bagasse used in this research (Thomas and Scott., 1962).In broilers that had their corn partially replaced by cassava bagasse, values close to 2.00 were observed for feed conversion and approximate values of the present research for weight gain, being considered good results for the species, corroborating with statements made on the quality of licuri bagasse for feeding these animals (NASCIMENTO et al, 2005).The variables, weight gain, feed conversion and feed intake did not show significant differences in broilers during the growth phase, when fed with increasing levels of babassu bagasse in the diet, similar results to those found in this research, which allows to infer that at this stage the use of alternative sources of food from oilseeds does not interfere with the zootechnical performance of the animals, as long as they are used in the correct dosages (SILVA et al, 2015).…”

Effect of shed rooftype and babassu pie on the productive characteristics of meat quails

“…However, there was an increasing linear response in the GRW (%), according to the equation GRW (%) = 2.154 + 0.012 BP (r 2 = 0.81). Similarly, Silva et al (2015b), who evaluated the effect of replacing soybean meal by BP (0,10,20,or 30%) in the rations of Cobb 500 strain broiler chickens, observed that the gizzard relative weight increased linearly due to the increase in fiber content, which corroborates our own results.…”

“…Similarly, Silva et al (2015b) found that the levels of substitution of soybean meal with babassu pie did not affect carcass, thigh, quarter, and breast yields in sacrificed chickens at 42 days of age, indicating that babassu pie can substitute up to 30% of the soybean meal in the rations (corresponding to a level of 8.4% of BP), provided these meet the nutritional requirements of the birds.…”

“…Similarly, Carneiro et al (2009), who evaluated different levels of BP (0,3,6,9,and 12%) in rations for Hubbard chickens from days 22 to 42, showed the technical feasibility of including up to 12% of BP in rations. Silva et al (2015b) analyzed increasing levels (0, 10, 20,and 30%) of soybean meal replacement by BP in rations for broiler chickens and showed no effect on the WG and FC of birds, recommending the substitution of up to 30% of the soybean meal with BP, which is equivalent to the inclusion of 8.4% of BP in rations.…”
