Effect of caponization on growth performance and blood parameter in Fayoumi Cock

Caponization is generally supposed to affect the growth performance, carcass composition, and meat quality of male chickens. The present research work was conducted on 90-day-old Fayoumi male birds at Shahedul Alam Quaderi Teaching Veterinary Hospital Chattogram Veterinary and Animal Sciences University during the period from August 2018 to October 2018. The objectives of the study were to evaluate the effects of caponization on surgical efficacy and complications, growth performance, and blood parameter changes (CBC, serum protein, and glucose). The experiment was divided into two groups, an experimental group, and a control group with an equal number of birds (n = 10). Only the birds of the experimental group were caponized at the age of 90 days and reared for 62 days until they reached 152 days of age. Each bird in both groups was given equal care, feeding, water, and housing. Each bird was given a separate tag number for record-keeping. The present study revealed that 20% of birds died during surgery, and on the next day of surgery, 40% of birds were found to develop wind puff, and the average wound healing period was 6 days. The feed and water intake were slightly lower in the experimental group compared to the control group. There were no significant variations in body weight gain, feed, or water intake. Blood CBC (except PCV value and monocyte count), serum protein, and glucose levels were also not significantly changed between the two groups (p>0.05). But the present study revealed that caponization significantly decreases the PCV value of blood and significantly keeps the monocyte count stable with the age of poultry (p 0.05).
