Highly Concentrated Energy Source for Broilers

Abstract

Studies were conducted on the use of oil obtained from rapeseed cultivar 'Podmoskovnyj' selection of Federal Williams Research Center of Forage Production and Agroecology in feeding broiler chickens. The experiments were carried out on chickens cross-country "ROSS-308". They were grown in a cell battery. For the experiment, 5 groups were formed. In the start and finish periods, the control group received 2.5 and 3.3% sunflower oil. In the experimental groups, sunflower oil was replaced with rapeseed in the following amounts: the first — 1.0 and 1.0%, the second — 1.5 and 1.7%, the third — 2.0 and 2.5% and the fourth — 2.5 and 3.3%. Feeding was carried out with dry loose feed from a day old. Studies have found that rapeseed oil had less saturated and polyunsaturated fatty acids, but more unsaturated fatty acids. The amount of erucic acid was 0.20%. The digestibility of nutrients was high and practically did not differ from the control variant, as was the use of nitrogen. The inclusion of rapeseed oil in the composition of feed for broilers did not have a significant impact on the increase in live weight and feed costs. The cost of feed with increasing rapeseed oil in their composition decreased, and the efficiency of converting feed into products increased slightly. Compound feeds with rapeseed oil were not inferior in terms of the efficiency of using compound feed containing sunflower oil.

“…Установлено (6), что комбикорма с рапсовым маслом не уступали по эффективности таковым с подсолнечным маслом. Зарубежные авторы считают, что положительный эффект от применения рапсового масла в рационе выражается в увеличении содержания полиненасыщенных жирных кислот в мясе цыплят-бройлеров (7).…”
