METHOD OF BEEF PRODUCTION AT RECONSTRUCTION OF GROWTH STRUCTURE OF STAD AT DAIRY FARM Russian patent published in 2018 - IPC A01K67/02 

FIELD: agriculture.

SUBSTANCE: method of beef production at reconstruction of growth structure of stad at dairy farm, which includes a selection of animals in accordance with the desired genotype, the parameters of body weight with temporary life stages, growth energy, with intense feeding conditions on the regulations, types and quality of forages, optimal maintenance and protection from diseases. Culling of animals that do not meet the requirements is carried out, according to the invention the animals originally selected predominantly female (heifers), which are intensely cultivated, feeding additionally boiled fodder-starter and oat grains to six months age. First 8 weeks of life hay is not included in the diet. Heifers are weighed every month with the definition and correction of the conditions for growth and development. Selection of heifers for insemination and insemination of heifers that have reached the planned body weight from the age of 14 months in carried out during the hunt with the sperm of bulls-producers' improvers. State of the course of pregnancy, intrauterine development of the fetus is determined. Calving is organized, the newborn calf is weighed. After calving, heifers are milked for control every decade, and from 20 to 30 days after calving using daily milk yield and the monthly recalculation coefficient milk productivity during the first lactation, the suitability of the animal to machine milking and industrial technologies maintenance, as well as the exterior and body weight of the animal is determined, and then the status of a replacement heifer, if its characteristics correspond to established by the regulations ranges: age, body weight, exterior, the calf is born alive, the level of milk production, suitability for machine milking with further transfer act of such animal in the cow and replacing culled from the stad cow with it. Production of meat in body weight of replacement heifer is calculated using the following formula: PM = Hr + C + (Ca-Hr) = T + Ca, where PT is produced meat in live weight of replacement heifer, kg; Hr is body weight of replacement heifer on the fifth day after calving, kg; C is live weight of a body weight of live calf at birth, kg; Ca is average body weight annually culled and retired cows on the farm for the preceding calendar year, kg.

EFFECT: invention allows to increase the livestock, livestock weight body and meat production by changing the structure of stad.
