The productive effect of a complete ration compound feed, balancedaccording to international standards for individual available amino acids, on thegrowth, development and functional state of the organism during the cultivation ofrepair young rabbits was determined. Animals of the control (I) group were fedgranulated complete ration compound feed, in which the indicators of the contentof the main available amino acids (lysine, methionine and threonine) were nottaken into account during rationing, and the analogues of the experimental group(II) - taking into account these factors - approximated in terms of nutrition. It wasestablished that the average live weight of animals in the control (I) group was968.9 g, in the experimental (II) group - 965.7 g (difference 0.32%), and at the endof the experiment - 2480.4 g and 2446.4 g , respectively (the difference of 1.39% isstatistically improbable). The absolute increase in live weight of animals was: inthe I-group - 1511.5 g, in the II-group - 1480.7 g (the difference - 2.08% is notstatistically probable). A similar trend was observed in terms of relative growth -157.3% and 153.5%, respectively (a difference of 3.8%). When determining feedcosts, it was established that during the entire period of the experiment, per 1head. 8.59 kg of combined feed was fed in the experimental group and 8.51 kg inthe control group (difference 0.93%), the average daily consumption was 179.0 gand 177.3 g, respectively. Feed costs per 1 kg of live weight gain of young animalswere: in the II-group – 5.80 kg and in the I-group – 5.63 kg (difference – 0.17 kgor 2.93%). The waist width of both groups of rabbits was 5.3 cm on average, andthe index of the comprehensive assessment of the young was 214.9 in the controlgroup and 211.0 in the experimental group; the difference was equal to 3.9 or1.85% and was not probable. Thus, repair females of both groups during thegrowth period from 42 to 90 days did not significantly differ among themselves interms of these parameters. Average pre-slaughter live weight 1 head. in theexperimental group it was 2461.3 g, and in the control group - 2457.5 g (difference0.16%), the slaughter weight of the carcass was 1407.5 g and 1405.3 g (difference0.16%), respectively, the slaughter yield of the carcass in both groups – 57.2%, aswell as carcass length – 27.4 cm and 27.3 cm (difference 0.37%). The differencebetween the groups according to all the above-mentioned indicators is statisticallyimprobable. No significant probable difference was found between the groups ofanalogues and when weighing their internal organs. So, in particular, the weightof the liver in the experimental group of animals was 56.8 g, in the control group -57.0 g (difference 0.35%), kidneys - 16.5 g and 16.3 g, respectively (difference1.21%), hearts - 6.5 g and 6.8 g (difference 4.62%), lungs – 14.0 g and 13.8 g(difference 1.43%), as well as the total weight of skin 375.3 g and 373.0 g (adifference of 0.61%). When measuring individual indicators of the lineardevelopment of genital organs of repair females, it was established that theaverage length of the double uterus in the II-group equaled 5.8 cm, and in the I-group - 5.9 cm (difference - 1.72%) ; the average width of the uterus in bothgroups was 1.3 cm. Thus, no significant difference was found between the groupsof analogues in these parameters as well. Thus, it can be concluded that the use offull-rational granulated compound feed, developed according to internationalstandards, taking into account the rationing according to the content of individualavailable amino acids, allows to reduce the content of crude protein in it - by1.44%, as well as proportionally reduce the content of digestible energy - by8.86% and crude fat - by 0.47%, which, in turn, helps to reduce the cost of feedingredients per 1 kg of live weight gain by 5.84%.
