Title

Physicochemical and sensory characteristics of meat in Sussex (S-66) cocks and capons

Abstract

The objective of the research study was to compare the physicochemical and sensory characteristics of meat quality in cocks and capons. A total of 80 Sussex (S-66) cockerels were included in the research study; they were randomly assigned to two groups with 40 birds per group. Group I consisted of intact cockerels and group II comprised cockerels that were castrated in the 9th wk of age. The birds were fed the same compound feeds ad libitum and kept on litter under the optimal environmental conditions, at a stocking density of 7 birds/m2. At the end of the fattening, i.e. in the 24th wk of age, 8 birds with the body weights similar to the group average were selected for slaughter. After slaughter, there were determined the slaughter yield and the technological parameters of meat, and a chemical and sensory evaluation of the breast and leg muscles was performed. Based on the results obtained, it was concluded that, compared to the intact cocks, the Sussex (S-66) capons were characterized by a higher body weight, a higher slaughter yield, and the muscling of their carcasses was better. The breast and leg muscles of the capons were characterised by a better tenderness and a better water holding capacity. In addition, the castration had a positive effect on the crude protein content both in the breast and the leg muscles, which, in turn, had a higher content of crude fat and were distinguished by higher scores in the sensory evaluation compared to the intact cocks. Therefore, the meat of S-66 capons is a product of the particular, higher quality, and the cockerels that are not used for egg production could be more efficiently utilized through caponization.
