Effect of rapeseed Velles grain on the productivity and zootechnical parameters at growing of chicken-broilers

Rapeseed is an important source of feed protein and seed oil. The modern varieties and hybrids of this culture are characterized by ecological plasticity and high grain yield. In 2020 register new variety Veles, two-zero (00) type, was included in the State registry of breeding achievements of Russian Federation. The main agronomical important properties of this variety are a high fat content (43.7–44.0%) and reduced fiber level (6.5–7.2%). The study on using the grind rapeseed grain in feeding chicken-broilers «Smena-9» cross was conducted in the vivarium of the laboratory of zootechnical evaluation and standardization of feeds in the Testing center of Federal Williams Research Center of Forage Production & Agroecology. The inclusion of ground grain in the compound feed at a rate of 6.5% (by weight) did not reduce the zootechnical indicators during 36 days of broilers feeding and provided a bodyweight of 2.17 kg, feed conversion of 1.61 kg, safety of 100 %, respectively control group. At increasing the rapeseed grain content in compound feed to 8.5% (by weight), reduced the body weight of broilers by 2.06 %, increased feed consumption per 1 kg of body weight by 0.62 %. The livability was 97.1% relatively to control. By experimental researchers it was proved the expediency of partially replacing soybean meal and sunflower oil with grind grain of spring rapeseed Veles up to 6.5% (by weight) as component of compound feed when raising chicken-broilers «Smena-9» cross.
