Hawthorn contains a variety of organic acids. After oral administration, the acidity of gastric juice is enhanced, pepsinase activity is increased, and protein digestion is promoted; hawthorn acid stimulates gastric mucosa to promote gastric juice secretion; Hawthorn contains lipase, which can promote fat digestion; Hawthorn contains vitamin C and other components, which can increase appetite by oral administration; Hawthorn can regulate gastrointestinal motility, inhibit gastrointestinal smooth muscle in spastic state, and relax gastrointestinal smooth muscle. Relaxation of smooth muscle has an exciting effect. Hawthorn Extract,Dried Hawthorn Tea,Fresh Hawthorn Berry,Hawthorn Fruit Extract Lixian Spring Pharmaceutical Co., Ltd. , https://www.lxctyy.com
(b) to control the initial age of birth. The use of a sexually mature fasting method will have a good effect on delaying the age of first-born broilers and improving the egg production performance so that the birds can achieve high and stable yields. The specific approach is: starting from the chicken production rate of 5%, fasting 8-10 days.
(c) Scientific feeding times and times. In order to maintain a strong appetite for the flock, a certain amount of time must be set every day to prevent the feed from being stored in the chute for a long period of time, causing the chicken to suffer from anorexia and picky eating habits.
(D) Drinking water should be timely. The chickens were cut off for 24 hours and the egg production was reduced by 30%. It took 25-30 days before returning to normal. The chickens were cut off for 36 hours. The egg production could not be restored to its original level. The water cut for more than 36 hours will have some chickens. Stop egg production and cause moulting. Therefore, adequate drinking water must be supplied in a timely manner.
(five) feed some health sand. Whether it is breeder chickens or commercial laying hens, it is often necessary to feed gravel, especially for raising chickens in cages. The size of the gravel should be moderate, preferably 4-5 mm in diameter. The method of feeding is: the flat chicken can be placed in a sand trough, and the cage chicken can be mixed in the feed at a ratio of 0.5%.
Egg production pay attention to a few issues
(a) Feeding in stages cannot be ignored. The egg laying period of commercial hens is divided into three stages, and each stage is fed with diets with different nutritional levels to meet their egg production needs. During the early period of laying, from the beginning of production to the peak of egg production, the egg production rate is more than 80%. During this period, the nutrient content of protein, calcium, etc. in the diet should increase with the increase of the egg production rate of the chicken; mid-production period, ie During the period after the egg production peak, the egg production rate is between 65% and 80%; at the later stage of laying, the egg production rate is less than 65%. The content of protein, calcium, phosphorus in the latter two stages of the diet decreased as the egg production rate of the flock decreased.
