Quail growth and development dependeng on the level of crude fiber in the diet

Quailing has several advantages in comparison with other types of poultry - high growth rate, the dietary value of eggs and meat, the content of vitamins A, K, B1, B2 is higher than that of chickens, egg production occurs at 5-6 weeks of age, which speeds up the cost recovery. The main costs of quail are feeds - up to 60%. An urgent task in poultry feeding is to reduce the cost of rations, while maintaining its viability and productivity. Therefore, one of the ways to increase economic efficiency is the use of cheaper protein feeds; however, these feeds are characterized by a high level of fiber and low energy value. The article presents the results of the study of animal feed with different levels of crude fiber in the period of 0-28 days and its effect on egg production and egg quality of Japanese breeds in the laying period. Studies have shown that an increased level of crude fiber in the mixed feed in 0-28 day’s quails does not adversely affect the increase in live weight, egg production and egg quality in laying quails. Quail grew according to the growth schedule with a higher level of fiber 8.0% and 10.0% in the 2nd and 3rd experimental groups, respectively. Live weight in 28 days quails was: 141.3 g in the control group; 134.5 g in the first test, which is lower than the control by 5.0%; 129.9 g in the second test group, which is lower than the control by 8.0% and 128.2 g in the third test group, which is below the control level of 9.3%. In this case, despite the lag in the increase in body weight in the period of 0-28 days, the bird was able to compensate for growth in the period of 29-49 days. During this period, the females received the same feed in all experimental groups. By the beginning of egg-laying at 49 days, the layers reached the following live weight: 206.3 g in the control group, 212.8 g in the first test group, 218.6 g in the second test group and 211.2 g in the third test group. The cost of feed per quail was: 170.94 rubles in the control group, 174.65 rubles in the first experimental group, 161.81 rubles in the second experimental group and 153.7 rubles in the third experimental group for the entire period of experiment. This leads to the conclusion that the use of cheaper components in the compound feed during the growing period of 0-28 days quails is economically justified.
