Management of flat-raised broiler breeders!

The general prenatal period is defined as the period from 18 weeks to the start of production, which is an important period of physiological transition of broiler breeders from development to maturity.

The feeding management at this stage must first make a correct estimate of body maturity and sexual maturity, and then formulate a reasonable plan for weight gain, feed increase, and light increase, so as to connect it with the management of the laying period.

After 16 weeks, focus on weekly weight gain, rapid development of physical and sexual maturation.

All-ground litter flat breeding, 4 to 5 per square meter; the scaffolding and ground litter are mixed horizontally, and each square meter can raise 5-5.5 chickens, try not to exceed 5.5 chickens, otherwise the chickens will easily heat to death in summer.

After the breeder hen enters the expected date of birth, the body weight gain and gonad development are at the most vigorous stage, and the body is preparing for the forthcoming production. At this time, the physical and sexual characteristics change rapidly, and these changes can be used to correctly estimate the production start time. , in order to implement the light and feed plan.

Body maturity can be comprehensively assessed from three aspects: body weight, pectoral muscle development and main wing feather replacement.

Sexual maturity mainly depends on comb development, pubic opening, and fat deposition.

If there is a deviation in the weight at 20 weeks, the plan should be reorganized according to the problem. If the weight is lower than the standard weight, the time of adding light can be postponed appropriately.
