Autumn memorandum on animal husbandry management
Amino Acids are biologically important organic compounds composed of amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid. With biological significance, amino acids are important in nutrition and are commonly used in Nutritional Supplements, fertilizers, and food technology. Industrial uses include the production of drugs, biodegradable plastics, and chiral catalysts.

Spring lamb after the autumn fertilizer, if not reserved for species use, it is timely listed on the autumn fertilizer. All sheep that have suffered from chronic illness, thin and weak, long-term free-riding, and low production performance should also be eliminated after the autumn fertilizer.
Second, laying hens: forced moult In the natural light, hens hatched in autumn, after a year of production, usually in the fall of the next moult, stop production. Natural moulting varies and lasts for a long time. The egg production peak during the second laying period comes late and the peak is low. Therefore, artificial forced moulting must be performed and the whole group must be mowed.
There are many methods of forced moulting, such as the chemical drug method and the hormone method. In production practice, more conventional methods are used, namely methods of controlling drinking water, controlling feeding and changing light. On the first day to the 11th day, feed is stopped, the light is on for 8 hours, and the water is stopped for the first 3 days. On the 12th to the 13th day, 40 g of feed is given each day, light is irradiated for 9 hours, and the water is supplied; on the 14th to 20th day, each day is fed 10 grams, until the resumption of free intake, lighting from 9 hours a day, an increase of 1 hour per week, up to 16 hours, water supply.
Compulsory moulting chickens must be healthy. After the moulting is over, the feathers, excrement, and grass are cleaned up, immunized in time, and transferred to normal feeding.
Third, duck: pay attention to ventilation, strengthen the epidemic prevention
1. Strengthen ventilation. To ensure the air circulation of the duck house, such as the nighttime hot weather, the ducks screaming uneasy, you can drive the ducks into the pool water, you can also use artificial fans and other artificial ventilation.
2. With good feed. Miao ducks are raised to normal feeding after 7 days of age. Feed mix: corn 58%, bran 10%, bean cake 25%, fish meal 3%, shell powder 20%, bone meal 1.5%, salt 0.5%, per kilogram of feed containing metabolic energy 11.72 ~ 12.14 MJ, crude protein 18% ~ 19%. Feeding once every 3 hours after the first week of hatching; feeding 3 to 4 times daily after 20 days of age, and using paddy fields to grazing can reduce the amount of materials used.
3. Strengthen insulation. From the end of October, we must do a good job of cold insulation work to prevent cold winds from invading. When grazing, ducks should be rushed to warm sandy beaches, pond ditch, and drains to avoid wind and cold.
4. Strengthen the epidemic prevention. Frequently check the temperature in the house to observe the diet, defecation and activity of the ducklings, and usually add the compound of diarrhea net, oxytetracycline calcium salt, multivitamin, calcium tablets and other drugs to the feed to prevent the occurrence of the disease. Once the duck has developed, it should be treated immediately and the sick duck should be kept in isolation.
Fourth, cattle and sheep: do a good job in autumn, timely mating to the middle and late autumn, grass flowering and seeding, high nutritional value, is a good time to catch the fall, but also to ensure the safety of cattle and sheep overwintering and the spring to avoid the lack of spring next crucial period. In autumn, it is the season when the ewe concentrates on estrus, and it is necessary to ensure that all the fetuses are bred to the ewes of the appropriate age. First of all, we must ensure that the ewes are in good estrus in order to maintain the sensation of being above average; for ewes that are not estrus, we can inject pregnant horse serum and chorionic gonadotropin. Second, the ewes must be bred in time or artificial insemination, as far as possible fully equipped with full pregnancy. For pregnant ewes, we must strengthen management and prevent miscarriage.
V. Rabbits: Zhuang Qiu, grasping breeding
1. Strong autumn. According to rabbits of different ages, formulated according to feeding standards, appropriate increase in protein levels, lower energy feed, require feed nutritious, good palatability, easy to digest. Ensure that rabbits have sufficient green feed every day, such as grass and vegetables. Feed should be fresh and clean without mildew, deterioration, feeding time, quantitative, so that breakfast early feeding, dinner late feed. Young rabbits are fed 5 to 6 times a day, young rabbits 3 to 4 times, and adult rabbits 2 to 3 times. Provide clean and adequate drinking water. Add 0.5% vitamin B12, 0.5% vitamin C, and 0.5% sodium bicarbonate to the feed; appropriate amount of Houttuynia cordata, leeks, decocted juice, add a little vinegar, white sugar, give the rabbit to drink, can prevent stress, Promote rabbits long.
The temperature difference between morning and evening in autumn is very large, and young rabbits are susceptible to colds, pneumonia, enteritis, and other diseases. Therefore, it is necessary to observe rabbits every day so that problems can be detected in a timely manner so that no disease can be prevented and the disease can be treated early.
2. Grasp breeding. Strong fertility, neat future generations, fast-growing rabbits should be reserved for species use. Old, weak, and sick animals should be eliminated immediately. Select excellent reserved rabbits to supplement the rabbit population. Do a good job of mating female rabbit breeding work, timely check empty, timely breeding. Pregnant and nursing females should be fed protein, mineral, and vitamin-rich feeds. Grasp the newborn's clearance of the pups, feed supplements and weaned timely.
