Technological method of heightening efficiency of swine breeding in specialized farm

Abstract

The purpose. To study efficiency of different methods of placement of pigs under papillae of a sow. Methods. Productivity of animals was determined according to demands of «Instruction on bonitation of quality of pigs» and with the help of innovative method. Results. It is established in two runs that for farm the most effective method of placement of pigs under papillae of a sow is the following: strong pigs in a nest should be place to forward papillae, and weak ones — to back. It is proved that at such approach the authentic variance occurs at comparison of results of control group with indexes of IIIrd and Ist (monitoring) to such attributes: «specific weight of amount of weaners from number born», and «mass of a nest at a wean» at td2,1=6,38 and td2,3=6,34 by the first attribute, and td2,1=6,0 and td2,3=6,74 by the second attribute at number of degree of freedoms 38 in both events. Conclusions. It is expedient to make the first placement of strong pigs in a nest under the forward papillae of a sow, and weak ones — under back. That ensures in the further normal growth of pigs in a nest in conditions of adaptability to manufacture of their growth with human controller.
