Application of a feed additive based on vegetable oilcake and lactulose in the diets of fattening rabbits

Abstract

Purpose. Study the effectiveness of a new feed additive based on vegetable cake and lactulose introduced into the diet of young rabbits in order to increase productivity. Materials and Methods. During the research, the objects were rabbits of the Californian breed, which were divided into 2 groups (control and experimental), in each group of 15 heads, according to the principle of analogues, as well as a feed additive based on milk thistle cake and lactulose. Experimental studies on the determination of growth dynamics, determination of slaughter indicators, as well as biochemical and morphological indicators of blood were carried out in a complex analytical laboratory by using standardized research methods. Results. During the experiment, it was found that the introduction of "Lactu-Super" in the amount of 5% by weight of feed contributed to an increase in the concentration of erythrocytes, leukocytes and hemoglobin, which corresponded to a higher level of metabolism, as well as the pre-slaughter weight of animals by 3.7% and slaughter weight, slaughter yield of 141.6 g and 2.0% relative to the control group that did not receive the supplement. Conclusion. The results of scientific and economic experience have demonstrated the effectiveness of using a new feed additive based on vegetable cake and lactulose for fattening hybrid rabbits under intensive technology from the age of 45 days.
