Feed and feeding of breeding Chicken
The digestibility of breeding chickens is strong, from chick feed to breeding chicken feed, mainly to reduce the dietary protein level, in order to prevent premature production, but also to reduce the cost of non-productive feed. There should be an one-week transition period from chick feed to breeding feed, so that chickens can have a process of adaptation.
As the breeding chicken is in a period of vigorous development of muscle, bone, respiratory system, digestive system and reproductive system, although the quality of feed can be slightly reduced, the proportion of various nutritional elements must be balanced, otherwise it will affect the normal development of the whole chicken body. Especially for young chickens under caged conditions, if they do not get nutritionally balanced feed, the qualified rate of mature chickens will be reduced, and it will be impossible to give full play to their due production performance in the future.
The level of crude protein in the feed of 7-12-week-old chickens should reach 15.5%, and the metabolic energy should reach 2800 kcal / kg; the crude protein of 13-18-week-old chickens should be 14%, and the metabolic energy 2800 kcal / kg. The proportion of calcium and phosphorus should be balanced, calcium deficiency is easy to suffer from osteomalacia, too much calcium hinders the growth of chicks. The calcium content in the breeding stage should not exceed 0.8%-1.0%, and the ratio of calcium to phosphorus should be 1.2 ∶ 1.
Of course, if the flock is sick or mismanaged, the weight may not fall within this range. But in any case, 80% of chickens should weigh around 10% of the average.
Every time the feeding must be uniform, often check, it is found that there are more accumulated materials on some grooves, and there are no leftovers in some grooves, so we should always spread the materials evenly to prevent some chickens from eating too much and some chickens not eating enough. In order to make the chicken flock grow neatly, it is very important to do a good job of leveling, and it is best to equalize the feed between the two feeds.
Always pay attention to singling out the smaller and weaker chickens and feed them more feed so that they can catch up with the strong chickens. As long as a little effort is made in this regard, the weight gain and overall development of these weak chickens will be significantly improved after a period of care.
Because the metabolism is exuberant, the digestive ability is strong, defecation is also many. During the breeding period, the feathers of the chickens are constantly changed, and the henhouse is dirtier and more dusty. Should be diligent in cleaning dung and cleaning the floor, regularly scrub the sink and material trough, and pay attention to the environmental hygiene around the chicken house.

Prevention and treatment of vitamin b1 deficiency in pigs
The symptoms of diseased pigs are emaciation, rough coat, no luster, dry skin, loss of appetite, some vomiting, constipation in the early stage, like sheep dung-like balls, and diarrhea in the later stage. Limping on one or more limbs, stiff gait, difficulty standing, trembling. Palpation has no tingling and is slow to respond to stimulation. Low spirits, like to lie down, in a state of fatigue. Some have paroxysmal spasms. There is little change in body temperature. The onset was slow and the course of disease was more than 7 days. Control and feed a full-price diet that meets nutritional needs, and pay attention to the matching of fine rice bran, wheat bran, legumes, green vegetables and green vegetables.

Methods for prevention and treatment of swine winter dysentery
Winter diarrhea is swine winter epidemic diarrhea. The peak period is from mid-December to mid-January of the next year; the incidence is acute, the spread is rapid, the epidemic area is wide; the incidence rate is high, the mortality rate is low, and the growth and development of pigs are seriously affected. Symptoms The incubation period of the disease is generally 12 hours to 18 hours. Adult pigs appear watery diarrhea symptoms after infection. The diarrhea is gray at the beginning, gradually yellowish green, and smelly. Abdominal distension, vomiting, initial temperature rise to 40℃~41℃, once diarrhea temperature drop, mouth
