Study on the Influence of Lysine and Methionine Essential Amino Acid Supplementation of Compound Feed Recipes on Growth and Slaughter Performance in Jumbo Meat Quails Between 1 and 56 Days
Abstract
To establish the influence of the diet on growth and slaughter results, an experiment was organized on two batches of Jumbo meat quails between 1-56 days. To determine the optimal age for slaughter, slaughter was performed at 42, 49 and 56 days. The mean body weight at the age of 42 days was 243.60±4.80 g in the control group and 267.44±9.33 g in the experimental group, the difference between the groups being very significant; at the age of 49 days it was 271.10±9.20 g in the control group and 291.40±13.06 g in the experimental group, the difference being significant, while at the age of 56 days it was 294.80±12.80 g in the group control and 301.00±11.50 g in the experimental one, the difference being not statistically assured. The results obtained in the present study recommend the use of compound feed recipes in meat quails with higher levels of lysine and methionine in rising for 42 and 49 days, which ensures superior growth and slaughter performance in meat quails. At the same time, it is recommended to establish the optimal age for slaughter according to the specific consumption of compound feeds, an age that in the present experiment turned out to be 42 days, or 49 days if a larger carcass is desired.
