Addition mode of AA+ broiler breeder
The addition of AA+ peak material is different from the conventional system and the feather speed system. In order to better manage the feeding, the author proposes the regular feeding mode and attention point according to his own experience, and hopes to correct it. Feeding purpose Control the weight of the hens by providing appropriate environmental conditions and balanced feed to the broiler chickens from the time of laying the eggs to the peak of laying eggs, to ensure their health, physical fitness, good health, and Make it smooth to achieve an ideal egg production peak and produce as many qualified eggs as possible. Feeding principle The weight of the hens is always kept within the standard, and the feeding amount should be a small number of times. The increase of the daily feeding amount must be preceded by the increase of the egg production rate, that is, the hen needs to be added. The main reason is that the egg production rate of many individual hens is higher than the average egg production rate of the chickens. In the flocks with good uniformity during the breeding period, the egg production rate increases rapidly and the feeding rate is also fast. In general, the increase in feedstock requires sustainability, stability and nutritional balance. General law AA+ is sensitive to changes in feed volume and requires the best daily feeding. It takes 8-21 days from light stimulation to the first egg, and 10-14 days from the first egg to 5% egg production. From 5% to the peak of laying eggs, it usually takes about 21 days. Feeding time If the flock coefficient of variation is less than 10%, it is added when the egg production rate is 3-5%; if the flock coefficient is greater than 10%, it is added at 10% of the egg production rate. The AA+ egg laying peak should be given when the daily egg production rate reaches 60-65%. Starting from 5% of the egg production rate, until the peak is reached, the calculation method: It is estimated that the peak amount of the batch of chickens minus the actual amount of 5% of the egg production rate divided by 21 days is the amount of material that should be added every day. For example: The predetermined peak amount (165 g) - 5% of the egg yield (131 g) = 34 g, this amount is divided by 21 days, that is, the amount of material added per day is 1.62 g. If the laying of the eggs does not reach normal levels, the hens should not be fed unless the physical condition indicates that the lack of material is a problem. If the body weight grows normally, the extra feed is not only bad for laying eggs, but harmful to laying eggs. Estimation of peak feed volume In theory, the energy of 475 kcal per standard daily weight hen and 25 grams of crude protein per day. The general peak amount is between 160-175 grams, but the maximum amount is based on the energy level in the feed, the weight of the chicken population and the temperature of the house. If the temperature of the house is above 27 degrees, for every 1 degree increase, each chicken will lose 5 calories per day; similarly, if the temperature is below 20 degrees, each chicken will increase energy by 5 calories per day. Determination of peak amount of In the laying period, the hens feed on the main purpose of three aspects: physical maintenance, growth and egg production. Most of the energy that the hen consumes daily is used to maintain the body's needs, so the larger the breeder, the more feed it needs. Studies have shown that for every 100 grams of standard weight of the flock, each chicken should increase the energy of 8-9 calories per day. In actual production, the breeder manager should evaluate the overall condition of the hens during the breeding period, predict the peak egg production rate of the chickens in this batch, and plan the peak amount of the chickens accordingly. 3-Way Screwdriver,Magnetic Bits Screwdriver,Phillips Screw Driver,Precision Hand Tools Yucheng Weisite Measuring Tools Co., Ltd , https://www.wsttool.com
