Studying the Carcass Characteristics of Four Breeds of Iranian Local Pigeons

The aim of this study was assess the performance and carcass characteristics of. a number of 96 adult male and female pigeons were used in a completely randomized design with 4 treatments and 12 replicates (with local names: 1-Qazvin>s Kabood. 2-Parvazi. 3-Koohy namebar. 4-Tehran>s Sefid). All birds were randomly located in single cages, each cage had 2 birds (male and female) as one replicate. The diet was prepared using two kind of grains including wheat and bitter vetch. The feeders were filled every morning and the residues were weighed in the next day. The chicks were hatched and grown up alternately in a couple of cages and slaughtered at 30 days of age after 12 hours feed restriction. Average feed intake (eaten by parents and chicks) for producing a couple of mature chicks (30 days old) was 3956.4 grams. Average of feed intake in first and third treatments was not different, but a significant difference was observed (P<0.05) between first, second and fourth treatments. The average weight of birds> carcass ready to cook in first and third treatments were 242,8 and 257,2 grams and the difference was not significant. The average of feed conversion ration for the breeds were 5.69 , 5.85 , 5.61 and 5.68 respectively.
