Biological response to quails (Coturnix coturnix) given hydrolyzed feather meal at different levels

Abstract

Abstract The biological response is one of the important parameters to evaluate the performance of a farm. Each individual will give a different biological response according to the treatment applied. Feeding is one of the biological needs of the quail ( Coturnix coturnix ). The purpose of this study was to evaluate the biological response of quails to the treatment of hydrolyzed feather meal with different levels. A total of 100 heads quail, one week old were used as samples. The treatment consisted of four levels (L 0 = 0%, L 1 = 1%, L 2 = 1.5% and L 3 = 2%). Each treatment was repeated five times. The treatment was uses a unidirectional design of completely randomized design (CRD) a 4x5 = 20 treatment units. Each treatment unit was uses five heads quails. The duration of the observation process was 30 days. The data were analyzed statistically using ANOVA. The results showed that the treatment of hydrolyzed feather meal at different levels at a level of 2% did not had a significant effect (P>0.05) on all parameters. The biological response of the increase in body weight gain was in the range of 2.00-2.37 g/head/day. The highest body weight in the treatment with L 3 (2%), in weeks 3 and 4. The average intake of feed was 14.84-15.79 g/head/day, the feed conversion was 0.60-0.68 and the in vivo digestibility of the protein was 40.48-51.69%. The results of the study indicate that the introduction of broiler feather meal from the hydrolysis in the quail feed ( Coturnix coturnix ) at a level of 2% has the same biological response. Therefore, an introduction with a level of >2% should be applied to discover the differences between treatments.
