The application of activated pine nut shell in quail feeding

Abstract

The purpose of the research was to experimentally substantiate the effectiveness of using a new feed additive – activated pine nut shell in quail feeding. The effect of pine nut shell feeding activated and non-activated on the growth rate of quail chickens, meat productivity indicators and blood biochemical parameters has been studied in a comparative aspect. An experiment lasting 74 days was carried out according to the generally accepted method on Japanese quails formed at the daily age in three similar groups (control and two experimental) of 40 heads in each. All groups received compound feed prepared taking into account the age and physiological characteristics of quails. In addition to the main diet, pine nut shell of diff erent treatments was introduced into the diets of young animals of the 1st and 2nd experimental groups in a dosage of 0,04 g/kg of live weight. Crushed pine nut shell was introduced into the diet of the 1st experimental group of quails, and the shell activated at the experimental installation of the Siberian Branch of the Russian Academy of Sciences was introduced into the diet of the 2nd experimental group of quails. The quails were housed in a cage battery under the required microclimate conditions. The results of the control slaughter of poultry showed that the weight of the gutted carcass of quails of the 1st and 2nd experimental groups was more than in the control group by 23,97 and 23,6 % (p < 0,05), the slaughter yield was higher by 11,6 and 6,8 %. Preparations containing activated pine nut shell had an impact on the growth and vital trats of quails. The best effect was provided by preparations with activated pine nut shell.
