| Popis: | Nutrition of rabbits is a complex of mechanical, chemical, and microbiological processes involved in the sequential breakdown, absorption, and use of feed nutrients and is determined by age characteristics. The most apparent aspect of feeding cows is the frequent consumption of small portions. For free access to the river, the frequency of the use and application of the poles is an average of 25–30 steps per day with a frequency of 5–10 min. A young man consumes coffee more often, which is related to the anatomical-physiological and age-related characteristics of the intestine and the function of its digestive tract. For example, at the age of 1 month, after the chicks are separated from the mother, the frequency of the first chicks reaches 50–60 chicks per day, which decreases to a maximum of chicks at 3.5 months of life. Complete nutrition of rabbits is possible if the rations are balanced in terms of all nutritional components, considering the maximum number of limiting feed components and their digestibility. The aim of the work was to study the influence of the new feed additive Prebiolact-KP on slaughter parameters in feeding young rabbits. The scientific and economic experiment material was rabbits of the modern meat hybrid HYPLUS selection of the company Grimaud Freres Selection. Four groups of twenty-five animals each were selected for the experiment based on the principle of analogs. Use compound feed with Prebiolact-KP in a dose of 1.5 g/head while raising rabbits. per day significantly improves slaughter qualities. The expediency of using a complete ration granulated compound feed with a prebiotic preparation has been experimentally proven. Feeding rabbits combined feed with a prebiotic preparation contributes to an increase in pre-slaughter weight by 2.7 %. The weight of the carcass with kidneys was more remarkable compared to the control group by 4.1 %, the longest back muscle by 3.4 %, pelvic limbs by 2.3 %, heart by 2.1 %, lungs by 7,1 %, liver – by 8.6 %, kidney – by 6.1 %, stomach – by 6.4 %. |
