The use of full-fat soy meal in compoundfeeds for meat chickens breeding line of selection SSC "Smena»

Abstract

The article presents the results of research on the use of full-fat soy flour in compound feeds for meat chickens of the initial selection lines of SSCh "Smena". The work was carried out on two baselines of the bird: B5 - the paternal line of the fatherly parent Cornish form, fast growing. The main features selected are feed conversion, growth rate, meat quality; B9 - the maternal line of the parent breed of the Plymouth breed form, selected by egg production, hatchabil-ity, growth rate, feed conversion, viability. The research task was to determine the effect of different levels of full-fat soy flour in compound feeds on zootechnical indicators of meat hens of the B5 breed lines (Cornish breed) and B9 (Plymouthrock breed), and to evaluate the effect of these feeds on the activity of digestive enzymes in blood plasma. Thus, we have established that full-fat soy flour is a valuable protein and energy product. It contains 14.75 MJ of exchangeable energy per kg; 34.9% crude protein; 17.24% crude fat. This study showed that induction of full-fat soy flour at the amount of 5 and 10% in the ompound feed of laying hens of the original lines with a balanced feed of amino acids and other nutrients has a positive effect on metabolism and allows you to get good zootechnical indicators.
