THE T. ВRIEDZHESA MODEL AND INTENSITY OF RABBITS GROWTH PARAMETERS IN PURE BREEDING AND CROSSING
Growth of rabbits and female rabbits was studied in pure breeding and crossbreeding. A high correlation relationship was established between the parameters of the kinetic and exponential growth rates of the T. Bridges model and the growth intensity with live weight of rabbits. There is a probable difference between the live weight of young animals when breeding rabbits breed white giant with rabbits breed Belgian giant (flanders): 20 and 25 g in the lunar age; 119 and 130 g in two months old; 260 and 270 g at three months old; 265 and 335 g at four months of age, respectively, of rabbits and males, indicating their high growth energy. It has been established that the increase in live weight of animals is associated with correspondingly higher asymptote parameters, which has a minimum value for purebred individuals (2.41 kg), and the maximum in the variant BV × BLV (3.28 kg). In groups of animals with greater growth energy, higher constants of kinetic growth rate (from 1.7908 in purebred rabbits to 1.9654 in the combination of BV × BLV, in males, respectively, from 1.7071 to 1.8298) are also observed. The exponential growth rate had an inverse relationship with the growth energy of animals. The index of uniformity of growth increases with the increase in live weight of animals and has maximum values in the mares BV × BLV. At the same time, the growth stress index has a much smaller range of variability, but is also positively related to the level of live weight of animals.
