Analysis of Reproductive Performance of Binary Crosses Between Dabao and Shiqi Pigeons and Production Performance of Crossbred Offspring
[Objective]This study was aimed to understand the reproductive performance of binary crosses between Dabao and Shiqi pigeons and the production performance of crossbred offspring,so as to provide data support for the subsequent establishment of high production performance matching lines.[Method]The experiment established orthogonal(the offspring from cross between male Dabao pigeons and female Shiqi pigeons were DS pigeon)and anticross(the offspring from cross between male Shiqi pigeons and female Dabao pigeons were SD pigeon)cross groups to measure and analyze the reproductive performance of breeding pigeons,the growth performance of cross offspring from 0-28 days of age,the slaughter performance of squabs at 28 days of age,meat quality and conventional nutrients,amino acid and fatty acid contents in breast muscle,as well as the serum biochemical indicators of squabs.[Result]The fertilization and hatching rates of DS breeding pigeons were significantly higher than that of SD breeding pigeons(P＜0.05).The body weight of SD pigeons at 14 days of age was significantly higher than that of DS pigeons(P＜0.05),the carcass rate,semi-eviscerated rate and eviscerated rate were significantly lower than that of DS pigeons(P＜0.05).pH45min of SD pigeons was significantly higher than that of DS pigeons(P＜0.05).The a*value and drip loss of DS pigeons were significantly higher than that of SD pigeon(P＜0.05).SD pigeons had a smaller diameter,a greater total number of pectoral muscle fibers,and a greater density of pectoral muscle fibers compared with DS pigeons(P＜0.05).The total protein and triglyceride levels in serum of SD pigeons were significantly lower than that of DS pigeons(P＜0.05).The blood glucose levels and total antioxidant capacity of SD pigeons were significantly higher than that of DS pigeons(P＜0.05).[Conclusion]DS and SD pigeons had excellent production performance and slaughtering traits,as well as good meat quality characteristics.The results provided a scientific theoretical basis and reliable data support for the breeding of high-yielding supporting lines for meat pigeons.
