The optimal content of winter wheat straw flour in the composition of animal feed for the reproductive performance of local rabbits was investigated. Recipes andsustenance for animal feed were calculated by physiological standards for the intensive technology of rabbit production. The analysis indicates that the experimental diet was balanced in all respects nutritional and biological value, in accordance with European standards. To accomplish the task, 4 groups of rabbits NTC (three-pedigree hybrids) were formed by the method of peers with 15 animals in each group.
According to the research, the optimal content of winter wheat straw flour in the animal feed rabbits (15% by weight) was established. An increase of wheat straw flour to 20% (IV group) in the feed composition results in a decrease of milking in rabbits by 6% (P<0.05) compared to control and the III research group.
The number of multiple pregnancies in all groups was within 7.80–7.93 newborn animals, fetus size was within 59–61g, the amount of milk was 2.50–2.67 kg with the maximum results in rabbits of III group.
Due to the indicators of quality of rabbit nest in the age of 35 days, the best results were set in rabbits of III group. The number of animals was 6.93 and the weight of nest was 4.76 kg, which was 1.5–1.9% higher than in control.
It is proved that the preservation of young animals was higher in rabbits of I, II, III and IV research groups and was 95.37, 94.54 and 94.39%, respectively, while in the control group it was 93.54%.
The optimal content of winter wheat straw flour (15%) in the diets of rabbits provided the maximal reproductive performance of rabbits: multiple pregnancies increased by 1.7%, fetus size— by 3.3%; IRCR complex index (index of reproducing characteristics rabbits) — by 2.4 % compared to control counterparts.
