The management of leech nursery period is a crucial period related to whether or not the farm is profitable and whether it is normal development. It is the largest period of breeding in the leech breeding farm, and also the breeding period with the highest investment cost of the leech. The management technology is divided into the management and nursing The management of 貂 requires the following steps:
one. Management requirements for mother-in-law:
1 Eat well and eat is the basic guarantee. In the mix of feed to be diversified, animal feed and plant feed with a complete, animal feed in the sea miscellaneous fish feed and meat, eggs, milk mix and match feeding, is to ensure the quality of the mother's milk ingredients. There are both long bone protein and long organ amino acids. The ratio of protein in the ingredients is not only methionine and lysine in fish, but also tryptophan, histidine, leucine, and isobright in meat and egg milk. Acid, zinc, iron, calcium. Supplementation of essential amino acids that cannot be synthesized in the body is beneficial to the milk secretion and quality assurance of female fleas, and is a necessary condition for raising and promoting the survival rate and growth of diarrhea.
2. Gradually add the amount of feed: In order to keep the mother's body in the middle and upper body condition, we must constantly increase the amount of feed, increase the amount of feed by one-fifth in the first week after delivery, and increase the amount of feed every week after two weeks after giving birth. One-third, after three weeks, the mother-in-law began to feed her eggs into the small room. Do not increase too much too fast to prevent the leftovers and pollute the sanitation of the rooms. One hour after feeding, we must check it again. Most of them are clean, and a few are superfluous. It is advisable not to leave excess food. It is a good way to keep clean and normal appetite. .
3. Check the behavior of the mother-in-law regularly. When the mother is born, she will eat off the fetus and the meconium, and look for the corners to be suitable. Hew one by one and heat and insulate each other to increase the calories of the female's own calves. , It is best to give 8% of sugar water to drink. To reduce the gluttonous behavior. Also check the mother’s mental status and the color and shape of the feces of the mother’s coop under the cage.
two. Aberdeen management:
1. Nursing and examination: The daily morning and evening observations include the situation of breast-feeding, the number of babies being bred, and the sound of young pigs. If they do not eat enough, they will make milk with each other, the sound is louder, and there will be obvious body fat and body. The difference in leanness indicates that milk quality is lacking, so it should be replaced in a timely manner to find alternative breastfeeding.
2.: Observe it only once in two hours during the day. If any abnormality is found, it should be promptly remedied. In particular, it must be checked again at 10:00 pm. Careful examination is the first key step in improving the survival rate of Tsai.
3 Due to incomplete birth development of Aberdeen, it is necessary to stimulate the skin with light to promote the continuous growth of blood circulation of dermis and summer hair, and then close the eyes and sleep for 4 weeks, the liver to achieve normal function, so within 4 weeks after delivery All need insulation and quiet environment
4 The mother’s fear of breast-feeding is greater. I’m afraid that the enemy will snatch my beak. If there is a sudden sound, I will bite the baby or pick it up again and scurry again. In the blink of an eye, when it is not possible to be independent, it is better to keep quiet in the house and dim the light.
Third, note:
1Supply enough water: The otters are animals that stay up late and keep the characteristics of the kennel after they are domesticated. When the water is lacking, they will bite the larvae or bite them.
2 Pay attention to feed hygiene: The first is the prevention of mildew, mildew, and rancidity. The selected small mutilated fish is used. Due to the restrictions of offshore operations and labor procedures, the freshness is also different and it is not easy to be fresh. The key is To prevent corruption, the degree of corruption has a lot to do with the content of toxins. Although yellowish fish can eat, but the quality is poor, not only is the fat oxidatively denatured and the protein is also degenerated, and the mother quail eats the rancid feed and it will affect the juice. Quality, don't feed females during the feeding period. Followed by the selection of mixed fish species, detection of toxic dolphin fish, feed processing and processing links should be fine-grained.
(3) Feeding for feeds should be started at 5 weeks and should be weaned at 6 weeks and 6 weeks. Wealth should be separated from weaned ones and then weave for a week. Supplement milk nutrition.
