Production and usage efficiency estimation of expanded mixed fodders

As a result of Union State (Russia and Byelorussia) program conducting “Progressive resource-saving eco-friendly technologies and equipment for biologically completed mixed fodders development” innovative technology for mixed fodders expanding, including following basic operations: air-conditioning of grain-shaped mixed fodders; expanding of steamed mix; granulation of expanded mixed fodders; cooling of expanded mixed fodders; crushing of cooled expanded mixed fodders; classification of crush products or granules was developed. Production line for expanded mixed fodder of grain shape, granulated and small granules was developed. Efficiency of use of mixed fodders for chickens has shown the raised yield of meat for chickens of 3rd group (69.5%) in comparison with blank and 4th group (67.6 and 67.3%). Besides, chickens of 2nd group had the greatest weight of internal fat (34.2 g) in comparison with other groups. The analysis of the data on eggs-laying of hens-layers shows that eggs-laying of hens for the experimental period was in groups 61.1–66.6 eggs per 1 hen and depended on technology of mixed fodder preparation. However specified indicator was the highest for hens of the fourth group receiving small granules, and it was 9% above the blank group. At feeding expanded mixed fodders and small granules to hens-layers eggs-laying for 90 days of the registration period was 63.6–66.6 eggs, intensity of eggs-laying was 84.8–88.8%, the yield of egg weight was 4.2–4.4 kg at an expense of a forage for 10 eggs of 1.64–1.71 kg and 1 kg of egg weight of 2.53–2.57 kg. The conducted calculation of economic benefit of manufacture and use of expanded mixed fodders with application to growing of broilers was 4 512 900 rub.
