Pregnancy management
The rearing of the reared captive species (usually ended on or around March 15), after successful mating, the breeding species will enter the pregnancy period of 2 months (58-62 days). This is the most critical and most important stage in the whole breeding process. The correctness of the means of feeding and management will directly affect the number of litters and their overall quality, thus determining the level of aquaculture benefits.
The dietary standards for feeding to science are relatively strict, and gradual feeding methods are generally adopted to ensure the physiological and physiological changes in pregnancy. The amount of feed to be fed should start from about 70 grams per day, ie 40 grams of cornmeal, 30 grams of fishmeal, and one egg (adding to the feed) for every 5-6 dumplings. If you feed a full-priced feed, because it has a certain amount of fish meal in the feed, you can feed 70 grams of ingredients each day, and eggs can be added separately. The frequency of feeding must be twice a day, one each morning and evening, so that the nutritional intake of pregnancies is more balanced, which is conducive to the development of the carcass. On this basis, from the day of pregnancy (on the day of successful mating), the amount of corn flour and fishmeal is increased every 10 days. Every day flour is increased by 10 grams, fishmeal is increased by 5 grams, and eggs are increased by 10 pieces every 10 days. A dice can be an egg. After 50 days of pregnancy, 100 grams of flour and 50 grams of fishmeal were fed daily. Full price feeds are also raised in proportion to this increase. When foodstuffs are found in the food dish, it means that the feeding of feedstuffs is more and should be reduced. If the dumplings are very clean and unwilling to leave, it may be because the feedstuff is less and should be increased moderately.
Feed nutritious species are very sensitive to the taste of feed during pregnancy, slight changes will reduce or refuse to eat, to ensure that the feed taste consistent, especially full-priced feed and fish meal, can not be replaced halfway. Because of the current full-price feed on the market, each manufacturer's formula and additive content are different, and tastes are different. Once the materials are reloaded, it will inevitably affect the appetite of the species, which will be detrimental to the carcass. Since the diet of congealed pregnancies will continue into the litter-dividing stage of litter and dice, it will also “inherit†directly to the taste orientation of Aberdeen. Therefore, when farmers purchase feed and fishmeal, they should consider long-term plans and try their best to keep manufacturers in mind. The unity and brand consistency. When using self-contained food, it should be noted that the finer the corn flour, the better the added excipients and the more constant the types.
The medicine is regularly fed with auxiliary nutrient drugs for protecting body functions and enhancing physical fitness during pregnancy, such as vitamin B1, complex vitamin B, vitamin C, vitamin E, and cod liver oil. In addition, 40 tablets of calcium were fed every morning after 40 days of pregnancy, and 4 tablets of yeast tablets were fed for 50 days. On this basis, the farmers should also add liquid vitamin C every day for the first 10 days before they enter the expected date of pregnancy. It has been proved that the timely feeding of liquid vitamin C can greatly prevent and reduce the occurrence of red claw disease in young and puppies. What needs to be reminded is that during the pregnancy period, feeding and injections of other therapeutic drugs are stopped. Although sometimes there are some minor morbidities in pregnancy, it is generally restored by its own resistance. If blindly treated with drugs, it will cause harm to pregnant and carcass, and even miscarriage or stillbirth.
Health should ensure that after the gravida are pregnant, the weather gradually warms up and germs become active. Environmental hygiene will be very important. It is necessary to regularly clean debris and feces, and do a good job of sanitation and disinfection around the shed. Throughout the pregnancy, the breeding area must be kept quiet. Sudden noises or loud loud noises for a long time can make the breed irritability and sometimes lead to self-mutilation or miscarriage. At the same time, the keeper should be fixed during pregnancy, and regular replacement will make pregnant women feel unfamiliar, and it is unfavorable for raising a child.
The delivery room must be arranged with the correct timing to ensure that the delivery room is not affected by pregnancy. When grass curtains are laid and the delivery room is finished, it must be in the early (5 days) or late (45 days) stage of pregnancy. It is more appropriate to arrange the delivery room in the initial stage, and sometimes it may be a busy schedule because the species is not pregnant. The late layout must be carried out in 45-50 days with stable carcass and no impaired pregnancies. Premature may cause frightened pregnancies. If it is too late, it may be due to early maternity or wrong mating date. It will be too late to arrange the delivery room. Very serious consequences. The time to open the isolation door between the "living area" and the "birth room" of the coop must be 5 days before the expected date of production, so that the seedlings can have a familiar environment.
