“…Our own research indicates a lower ratio of PUFA n-6/n-3 acids in castrated birds, beneficial from the point of view of human dietetics. The lower ratio of n-6/n-3 acids in castrated birds has also been demonstrated by Sirri et al (2009), Franco et al (2016), Calik et al (2017) and Kwiecień et al (2018).…”

“…The results obtained are consistent with those of Rikimaru et al (2009) who carried out research on Hinai-jidori chickens. In addition, Kwiecień et al (2018), in their studies performed on native breeds of hens: the Green-Legged Partridge (Zk) and Polbar (Pb), showed higher content of monounsaturated fatty acids (MUFA), lower content of arachidonic acid (C20:4n-6) and higher content of saturated fatty acids (SFA), especially palmitic acid (C16:0), in capons of the Polbar (Pb) breed. Our own research indicates a lower ratio of PUFA n-6/n-3 acids in castrated birds, beneficial from the point of view of human dietetics.…”

The authors indicate that the lower motor activity of castrated birds, affects the better use of feed, which is associated with higher weight gain and the deposition of particularly valuable intramuscular fat.…”

“…Comparison of slaughter performance and meat quality of cockerels and capons by origin, age, breeding system and nutrition has been the subject of many studies (Tor et al, 2002, Rachman et al, 2004Tor et al, 2005;Sirri et al, 2009.;Symeon et al, 2010;Rikimaru et al, 2011;Sinanoglou et al, 2011;Volk et al, 2011;Symeon et al, 2012;Mahmud et al, 2013;Calik et al 2015;Kwiecień et al, 2015;Adamski et al, 2016 a, b;Amorim et al, 2016;Calik et al, 2017, Zawacka et al, 2017Kwiecień et al, 2018;Murawska et al 2019;Wojtysiak et al, 2019). The results of these studies unequivocally prove that as a result of the capon's surgery, the accumulation of fat tissue in the abdominal cavity, subcutaneous fat, and especially intramuscular fat increases, which makes the capon meat characterized by greater fineness, juiciness and tenderness.…”

The aim of the study was to determine the effect of caponizing on body weight and physicochemical properties of meat of the capons - hybrids obtained from the crossing of hens of the Yellow-Legged Partridge (Ż-33) breed with meat roosters. The study covered 80 roosters - hybrids, which were randomly assigned to two groups of 40 animals each (8 boxes of 10 pcs in each group). Group I (control) consisted of uncastrated roosters while group II included birds, which were castrated in 8th week of age under local anesthesia by a vet. Birds were fed ad libitum with the same standard diets and kept on litter under optimal environmental conditions with a stocking density of 7 animals/m2. At the end of fattening, i.e. in the 20th week of life, 8 birds with a body weight close to the group average were selected from each group for slaughter. After slaughter, the effectiveness of the procedure was checked (lack of testicles), then the slaughter performance of birds, physicochemical parameters of the pectoral and leg muscles were determined, and sensory evaluation was performed. The procedure of castration of roosters - hybrids had a positive effect on body weight, feed conversion ratio and carcass traits. The pectoral and leg muscles of the capons were characterized by better water absorption, brittleness and sensory evaluation compared to roosters. Among the assessed groups of birds there was also a variation in the coloring of whole carcasses and muscles, which were lighter (L*), more yellow (b*) and less red (a*) in caponized birds. In addition, the castration procedure had a positive effect on the total protein content in both the pectoral and leg muscles, which in turn, with a higher raw fat content, were distinguished by a favorable ratio of n-6/n-3 polyunsaturated fatty acids (PUFA). Based on the results, it can be concluded that the hybrids obtained from the crossbreeding of the Yellow-Legged Partridge (Ż-33) and Ross 308 meat roosters are good choice for capon production. They can complement poultry meat production with a niche product for consumers looking for products of exceptional quality.

“…Therefore, females should also be considered in addition to males. There are several articles in the available literature on the quality of meat of Greenleg Partridge capons compared to cocks [ 16 , 17 ], but there are no similar reports concerning hens of this breed. At the same time capons may be treated as the 3rd “sex category” which may influence not only the production effects or quality of meat but also some physiological traits of birds.…”

The aim of the study was to assess the influence of sex, including caponization, on selected physiological and productive traits of Greenleg partridge (GP) birds. The study material consisted of 120 GP chicks (40 females and 80 males), divided into 3 equal groups (4 replication in each) and kept in litter system and fed ad libitum. A total of 40 cocks have been surgically castrated. The body weight (BW) of birds were measured biweekly. At the age of 24 weeks 8 birds/group were slaughtered, their carcasses were subjected to simplified dissection. Blood samples were collected and among others biochemical profile of serum was established. The lowest BW, regardless of age, had hens. From 18th week capons had the highest BW and finally it was similar to cocks. Cocks demonstrated, significantly, the highest carcass yield, however, the biggest proportion of breast muscles were stated in capons carcasses. The effect of sex is very clear in case of abdominal fat pad. The highest proportion of it was found in females but the lack of sex hormones in capons also contributed to a higher fat accumulation. The serum profile showed that the sexual maturity of hens increased lipids content (cholesterol, trigliceroles) caused by laying production.
