Abstract
The study was conducted to assess the effects of surgical caponisation on the production performance, share of respective elements of the carcass, basic chemical composition and fatty acid profile of muscles of Greenleg Partridge cocks. Two hundred twenty healthy day chicks were randomly distributed into two experimental groups (caponised and un-caponised). The birds were caponised at the age of 8 weeks old and slaughtered at 23 weeks of age. It was observed that capons tended to consume more feed. The studies found that the caponisation has increased the content of fat and its share in body weight. Further, the caponization has led to an increase in the final body weight and the cold carcass weight in week 23 and an increase in the weight of the stomach. The weight of breast muscles and the content of both depot fat and intramuscular fat was shown to have increased. Caponization caused advantageous changes in the fat profile, in particular of the thigh muscle in which the total content of MUFA and PUFA and PUFAn-6 was increased in capons.
