Background
The insemination capability of the breeding cock is one of important factors for determining the hatching performance of a breeding farm, and the breeding cock breeding management level has important influence on the insemination capability of the breeding cock and the production performance of offspring thereof (the technical key point of breeding cock management, shandong poultry, no. 10 2003). Standard body weight and good skeletal development are the basis for breeding good replacement cocks and maintaining good fertility to the maximum extent during the laying period of hens (management of breeding cocks, foreign zootechnics-pigs and birds, 2006, 26 nd 3 rd). 85% of the skeleton development of the breeding cock is completed in the first 8 weeks, 95% of the skeleton development is completed in 12 weeks, the reproductive system and testis of the breeding cock begin to develop at the age of 10-15 weeks, and the hormone secreted by the reproductive system at the age of 16-24 weeks enables the testis to develop rapidly.
The breeding management factors for promoting the weight and bone development of the replacement cock to reach the standard, represented by the length of the shank, have important influence on the growth and development of the replacement cock due to environmental factors such as temperature, humidity, ventilation and density besides the nutrition of the feed, particularly the breeding density, the breeding density of the replacement cock is generally the lowest on the ground and the lowest on the net, and the three-dimensional cage breeding is the highest. With the improvement of the stereoscopic overlapped cage breeding scale level of the reserve cock, the reserve cock mostly adopts a one-section overlapped cage breeding mode at present, namely the reserve cock is bred in the same cage from the shelling to the artificial insemination or before the mating utilization, and the breeding effect and the breeding efficiency of the reserve cock are more prominent due to the suitable cage specification and the breeding density in different stages. The specifications of cages for the replacement cock overlapping cage culture are greatly different due to different varieties and purposes of chickens. As the body type and the weight of the parental breeding hens of the laying hens are obviously different from those of the broiler breeders, generally, the size of a cage body of a standby hen is mainly that the length, the width and the height of each single cage are less than 1 meter and 3-4 layers, and a separation net is arranged between the two corresponding single cages before and after the same layer, if the group expanding is not timely performed, the feeding density is reduced, the activity space of the chicken is easily limited, the activity of the standby cock is reduced, the growth and the development of the skeleton of the chicken are easily hindered, and the physique of the standby cock is reduced.
Therefore, in order to overcome the defects that the single cage size of the cage of the parent-generation hen farm of the laying hens is small at present and the growth and development of the breeding cock are influenced, the cage of the backup hen of the parent-generation hen farm of the laying hens cultivated in one section, the breeding density and other feeding processes are needed to be optimized, the relative activity area and the welfare level of the cock in the cage are increased, the cultivation effect of the backup breeding cock is improved, and the insemination capability of the whole breeding cycle of the breeding cock and the production benefit of the breeding farm are improved.
