Substituição parcial do farelo de soja por farinha de sangue bovino em dietas de codornas européias (Coturnix coturnix) sob desempenho produtivo e rendimento de carcaça.

Abstract

Due to the high cost of protein sources from the processing of cereals, the use of alternative sources resulting from the processing of animal products makes it an excellent alternative for cost reduction in ration formulation for monogastric production. The objective of this research, evaluate the use of bovine blood meal (FSB) on performance and carcass yield of European quail (Coturnix coturnix) mixed in the period 1-21 days of age. A total of 300 quails in cages overlapping fed chow and water ad libitum during the entire experiment. We used a program natural artificial light 24 + hours. A total of 300 quails, not sexed, distributed in groups of 10 birds each and subjected to six levels (0, 2, 4, 6, 8 and 10%) inclusion of bovine blood meal, with five replications in a completely randomized randomized design (CRD), totaling 30 plots. The experiment was divided into two phases was: pre-starter from 1 to 7 days of age and starting from 8 to 21 days of age. We evaluated the weight (g), weight gain (g / day) and feed conversion (g / g) in both phases: from 1 to 7 and 8 to 21 days old. At 21 days, were evaluated yields by carcass yield, breast and legs (%). From the results obtained, it was observed for the pre-initial difference was significant only for variables GP and CA. In the period 8-21 days of age, there was a significant difference for all variables CR, GP and CA. Assessing the length of the birds showed an increase of this variable at the level of 6% compared to the 10% level. For the variable breast weight, there was an increase of weight when included FSB up to 8% in the diet. For the variable weight, it was observed that the best weights were acquired by adding 6-8% of FSB. Already analyzing carcass weight and legs, it was observed that the highest yield and weight were seen when 6% FSB included in poultry feed. It is concluded that the inclusion of up to 8% bovine blood meal in partial substitution of soybean meal in diets of quails, proved to be a viable alternative in the initial creation, improving the levels of performance and yield carcass.
