“…However, they found a similar ADG like the current study. Although a similar BWG and ADG has been reported in egg-type male growing chicken, no significant differences were reported between basal and low probiotics (1 gm/l) fed to crossbreds of Fayoumi and Rhode Island Red cockerels [ 15 , 16 ]. Despite the few studies, the majority of the results stated that probiotics have a greater effect on BWG of the birds than that of antibiotic growth promoters [ 2 , 3 , 11 , 17 – 25 ].…”

Objective: The current research aimed at investigating growth performances and meat yield characteristics of commercial cockerels supplemented with antibiotics and probiotics to the diet. Materials and methods: A total of 1,350 commercial cockerels (ISA Brown) were indiscriminately distributed to 3 treatment groups, each having three replications of 150-day-old chicks based on completely randomized design. The basal diet was treated as the control, while the experimental groups receiving Enrofloxacin 1 gm/kg and Protexin 1 gm/kg feed were considered as antibiotic and probiotic groups, respectively. Bodyweight, feed intake (FI), feed conversion ratio (FCR), and other relevant characteristics were recorded weekly until 49 days of trial. In the end, similar number (10) of birds from each replicate group were slaughtered to determine the carcass characteristics. Results: Significantly, better results were found in the overall growth performances of the cockerels in the probiotic-fed treatment group. Highly significant differences were also found in live bodyweight, weight gain, daily gain, FI, FCR, survivability, dressing percentage, abdominal fat, breast meat, drumstick, and thigh weight in the probiotic-fed treatment group compared to the others. Conclusion: The results of the present study indicate that the inclusion of dietary probiotics has a superior performance to antibiotics and may have the potentiality to be used as an alternative growth enhancer in the diet of cockerels.

“…According to the reports, type II fibers were found to have higher glycogen contents, and therefore, higher glycolytic potential ( GP ), than other fiber types in pork ( Monin et al., 1987 ; Choi et al., 2007 ). Many previous studies have shown the growth performance, carcass characteristics, and meat quality of fast- and slow-growing commercial broilers ( Choo et al., 2014 ; Zhao et al., 2019 ; Biesek et al., 2020 ). However, there are only a few studies conducted on the comparison of muscle fiber characteristics and GP of breast and thigh muscles from fast- and slow-growing commercial broilers ( Zhao et al., 2012 ; Verdiglione and Cassandro, 2013 ; Shu et al., 2017 ; Mazzoni et al., 2020 ; Weng et al., 2022 ).…”

Muscle fiber characteristics had beneficial effects on meat masses and meat quality in broilers. Its number is determined at birth and directly affects the growth and development of muscle fibers after birth. However, whether the muscle fiber characteristics in different types of chickens are different at birth has not been fully documented. In this study, the 1-day-old Xueshan chicken (slow-growing broiler) and Ross 308 broiler (fast-growing broiler) were selected, respectively, and the fiber type distribution, fiber density, and fiber size in the breast ( pectoralis major , PM ) and leg ( gastrocnemius , GAS ) muscles were detected. The results showed that the PM only made up of type IIB fibers regardless of breed, and that few type I fibers (approximately 17.55%) was identified in GAS of Ross 308 broiler. The PM muscles had significantly higher fiber density, lower cross-sectional area and diameter than those of GAS muscles in both 2 breeds ( P < 0.05). The highest fiber density was observed in PM of Xueshan chicken. Furthermore, the muscle fiber characteristics were partly controlled by glycolytic potential ( GP ), and the GP was also invesgated. The GP in PM and GAS of Ross 308 broiler were higher than in Xueshan chicken ( P < 0.05). Taken together, 1-day-old Xueshan chicken exhibited higher fiber density and lower GP compared to 1-day-old Ross 308 broiler, especially in PM, which could not only reveal the differences of muscle characteristics among different types of chickens, but also explore a new way to improve the masses and quality of poultry meat.

“…Raising unwanted cockerels for meat is the approach that has met with the highest degree of social acceptance (Bruijnis et al, 2015; Brümmer et al, 2017; Mueller et al, 2018). Due to genetically determined lower body weight ( BW ) gain and higher feed intake per unit of gain, the process of raising layer-type cockerels for meat takes longer and is less profitable compared with broiler chickens (Koenig et al, 2012; Choo et al, 2014). Leenstra et al (2011) and Brümmer et al (2017) investigated potential alternatives to the killing of day-old male chicks of layer breeds and found that some consumers declared their willingness to pay a premium for eggs and chicken meat to prevent the above practice.…”

The aim of this study was to determine the effect of age and caponization on the growth performance and carcass quality characteristics of Leghorn cockerels. The experiment was conducted on 224 Leghorn cockerels. At 8 wk of age, 112 birds were surgically castrated by a qualified veterinarian in accordance with Commission Regulation (EC) No. 543/2008. The birds were divided into 2 sex categories (with 8 replications per group and 14 birds per replication). The birds were raised to 28 wk of age, and were fed commercial diets ad libitum. From 12 wk of age, at 4-wk intervals, 8 intact cockerels and 8 capons (1 bird per replication) were selected randomly and slaughtered. Caponization had a beneficial influence on the feed conversion ratio (FCR). FCR (kg/kg) based on body weight (BW) gain, carcass weight gain, and edible weight gain was lower in capons from 24 wk of age ( P < 0.05), and FCR based on lean weight gain was lower in capons from 21 wk of age ( P < 0.05). The content of edible components expressed as a percentage of the total BW of cockerels and capons was similar in the corresponding age groups. Caponization had no effect on the total lean meat content of the carcass ( P = 0.744), but differences were found between the weights of breast muscles and leg muscles. In week 24 and 28, the weight of breast muscles was higher in capons than in cockerels ( P < 0.05). Cockerels had higher leg muscle weight than capons, and significant differences were noted in week 16 and in 28 ( P < 0.05).
