One of the key elements in the management of breeding roosters is to make chicks have a good start. The management of the brooding stage ensures the normal physiological characteristics of the roosters.
The first 72 hours of a bird's life are particularly important. This not only determines its ability to resist disease, the development of the cardiovascular system and the growth of plumage, but more importantly, this initial stage determines the chicken The development of the skeleton. Only when the roosters have a good skeleton development during the brooding and breeding period can they effectively mate throughout the entire laying period. In order for chicks to get a good start, it should be ensured that they grow completely in accordance with the weight curve within the first 14 days of age. In order to achieve this goal, many breeder farms use broiler chicks (without coccidiosis). For instance, if one breaks the locust within one day of age or one week of age, care should be taken to prevent it from becoming a cause of poor uniformity. The biggest factor affecting the uniformity of the flock after 14 days of age is whether or not the cock can obtain and eat the amount of material it should receive. The uniformity of the roosters is critical, and to maintain good uniformity, the feeding system must be able to provide accurate feed for all roosters at the same time. It is important to closely observe the behavior of the birds, especially the transition from manual feeding to automatic feeding of the feeding system to ensure even feeding and to ensure even growth of the birds. While obtaining the correct weight growth curve, the uniformity of the male rooster should be kept between 80% and 85% from the 35th day of age, so that the sexual maturity of the chicks is basically the same in mixed group and mating. By 8 weeks of age, 85% of the skeletons of chickens were almost complete. It is therefore crucial that this stage must be achieved, even beyond the early weight standards. Otherwise, the mature shape of the roosters is smaller than the ideal shape. Without a good skeleton, the breeder rooster tends to have a large degree of obesity, fat accumulation, and poor post-laying form, which limits the success rate of mating.
The standard that can help a male rooster to obtain the correct weight of the skeleton. To reach the target weight of 140 grams at 7 days (if necessary, feed a high-protein and high-energy starter). At the age of 4 weeks, the whole group is weighed. Column, at this time to eliminate particularly small chickens; for this species, the latest standard weight is obtained by 8 weeks of age; 10 weeks of age when the last seed selection work, if necessary, re-establish the weight growth curve, then to Don't do any work on the roosters at the beginning of the mating. To ensure that the breeder's stocking density is not to be crowded (should be 3 roosters per square meter - 4 roosters), to provide him with ample room to eat (15 cm/mouse), the feeder must be operating fast enough (most Fast 2 minutes / column - 3 minutes / column).
