The effectiveness of a phase system feeding of pheasants when intensive rearing for meat

Abstract

A new phase system of feeding pheasants at their intensive rearing for meat, enhanced by factors of amino acid and energy influence on the young poultry growth rate into account its feeding preferences has been developed and allowing to obtain the live weight of pheasants at the age of 17 weeks at the level of 900 g and more. With the use of this system the yield of gutted carcass of pheasant reaches 60–61 % of the pre-slaughter weight with a sufficiently high specific weight of valuable parts-breast (40–42 %) and legs (29–30 %). In the proposed system of poultry feeding the same type of corn grain component of compound feed is more effective when it is 55 % by weight,. The experimental data confirm that the corn type of feeding pheasants intensively reared for meat, contributes to the activation of feeding behavior of young poultry. At the same time, the total time of feed consumption by poultry per head in comparison with the use of a set grain feeds (wheat – 15 %, barley – 11 %, corn – 31 %, peas – 8 % by weight) significantly increases by 12–13 minutes per day. The increase in feed activity is one of the factors allowing to increase the live weight at 17 weeks by 112,9 g or 14.5 % (P < 0,001) and the weight of pheasant legs after slaughter by 20,0 g or 14,7 % (P < 0,05). At the same time feed expenditures per 100 g of growth are reduced: dry matter by 0,12 kg (22,2 %), metabolic energy by 1,51 MJ or 20,8 %, and raw protein by 0,03 kg or 25 %. The preferential use of corn for fattening makes it possible to reduce the sale price of young poultry of meat purpose in live weight by 53–54 rubles or 15–16 %, and in the form of gutted carcass by 58–59 rubles or 9,5–10,0 %, which increases the effectiveness of pheasant meat production technology.
