Solve difficult problems and lay the foundation for the most important To solve the problem of pregnancy in the fall, we must do a good job in three areas. This is the premise and basis. First, we must adjust the population structure. The male and female rabbits of the appropriate age are selected first, with clear pedigree, robust physique, excellent production performance and hereditary stability. As far as production performance is concerned, the rabbit needs large size and high wool production; the rabbit needs fine and smooth hair, and the rabbit has good growth and feed conversion rate. Male rabbits should focus on breeding ability and good semen quality; female rabbits should focus on the ability to breastfeed and have good nursery habits. Young rabbits can also choose some appropriate ones. Second, we must strengthen feed nutrition. This is the material basis for improving the breeding of rabbits in autumn. It is important to have enough quality green feed. Particulate feed must increase protein content, so that amino acids, especially sulfur-containing amino acids, can be balanced to the standard. It is advisable to control the level of dietary protein in the range of 16% to 18%. Rabbits may be high, rabbits may be low, and rabbits may be centered. To add calcium, phosphorus, zinc, selenium and other trace elements; add A, D, E and other vitamins. Since the recovery of the rabbit body and the improvement of the semen quality require a process, the nutritional supplementation is carried out one to twenty days before the breeding, so that the rabbit's pummosis can be effectively controlled. It is advisable that the breeding male rabbits raised in the farm can start feeding one egg each day more than ten days before the breeding; the female rabbits can be fed with half or two big malts on a daily basis. Third, we must improve the environmental conditions for rearing. Pay attention to the control of the ambient temperature, the rabbit's critical temperature of 5 to 30 degrees Celsius, the actual breeding temperature is 15 to 25 degrees Celsius, the temperature difference between morning and evening in autumn, the sun is still fierce, the outdoor rabbit house still need to shade to cool. The cage should be ventilated and light-transmitting, do a good job in environmental sanitation, and provide a more spacious venue for rabbits, so that they can lay their cages in a certain period of time sooner or later to enhance their physical fitness. In case of rabbit breeding, it is difficult to raise and then choose well. 1. Choosing young male rabbits to breed in the same year, because of their youthful strength and energetic vitality, their vitality is strong and they are not affected by the season. 2, on the basis of the original rabbit diet, and then properly add some animal protein, such as fish meal, silkworm cocoon, feather meal, etc., to add 2-3% is appropriate. 3, all kinds of rabbits in addition to the appropriate supplement of sulfur-containing amino acids, can be used to comb the rabbit regularly comb the body in order to promote the body surface blood circulation, which will facilitate the end of the hair replacement and put into production. In addition, in order to prevent this kind of problem from recurring in the fall of the coming year, the temperature of the rabbit is reduced while the temperature is hot, and attention is paid to increasing the amount of protein, vitamins, and trace elements (especially trace elements associated with reproduction) in the rabbit feed. Follow the rules and pay attention to the method can be immediate To grasp the law of estrus and pay attention to breeding methods, this is the most direct measure and can receive immediate results. 1. The enhancement of sexual function recovery of male rabbits and the improvement of semen quality of male rabbits are fundamental to improving conception rates. As is well known, rabbits have high and low fetuses in terms of their fetuses, and how dominant and how powerful they are in male rabbits. Studies have shown that after a summer male rabbit has sexual desire and can only produce one third of the sperm, the general rule is that the meat rabbit is better than the rabbit, and the rabbit is better and the rabbit. To solve this problem, according to the existing experience, the following methods can be taken: 1 induce estrus, put flirtation, and close the relationship between male and female rabbits, and even directly put estrus female rabbits together with male rabbits to promote recovery of male rabbits' testicular function. 2 Testicular massage, three to five minutes each time, twice daily to promote blood circulation and stimulate testicular tissue hyperplasia. 3 hormone aphrodisiac method, every other day, to the male rabbit muscle injection row 0.5 micrograms on the 3rd, after five consecutive times rabbit male semen greatly improved. It should be pointed out that there is a gradual process of sexual function recovery in male rabbits. Once sperm is killed, it usually takes 50 to 60 days to re-occur. Therefore, it should be fully thought-provoking, but it will surely have good results. 2. Breeding of female estrus in estrus is not the same as that in non-love period (the fertility rate in mating period can increase by 20% to 30%). As the saying goes, "Pink is early, purple is late, and old red is." In addition to inducing estrus, adolescent female rabbits may also use chorionic hormones, luteinizing hormones, triad hormones, and ovulation-promoting No. 3 for aphrodisiac; in female rabbits, 10% of epimedium or amaranth seeds are mixed in. Half the money, even for ten days of service is also effective; add 40 mg of carotene per kilogram of feed, female rabbit fertility rate will increase; long hair rabbit genital fluff after cut off seven to eight hours after mating, the effect is better. In short, a lot of aphrodisiac methods can be combined with the actual selection. 3, other measures to increase breeding fetus: 1 according to the characteristics of rabbits to stimulate ovulation, the implementation of repeated mating or double mating, compared to a one-time increase in the chance of 10% to 20% of the fetus. 2 Regular inspections, supplementation or treatment. After the female rabbits are mated on the eighth day after mating, they will be able to shorten their empty time. Found that the female rabbit ovarian cyst or long with infertility, can take a day of compound sulfamethoxazole tablets, and even served 7 to 10 days for treatment. Ovarian hypoplasia or atrophy of sexual function, intramuscular injection of 0.5 to 1 ml of ethylene estradiol every three days, even if the injection is effective five times. 3 Male and female rabbits have a strong physique. Under the premise of strengthening feed nutrition, frequency density (ie, blood allocation) and semi-frequent density (ie, milk allocation) can be used to greatly increase the conception rate and accelerate reproduction. In addition, the practice of artificial insemination for male rabbits can also play a role of “doing nothing when it comes to tenâ€.
Our special intermediates are mainly a combination of our own actual product structure and product properties, including: 1. The product does not belong to any other product of our company intermediates, 2. Chemical reaction type is more special 3. Can be used to synthesize two or more kinds of API which roles is almost equivalent and difficult to separate the level. 4. This intermediate is somewhat less used for actual production or less practical use. We summarized the above four cases of intermediates temporarily as a special intermediate, if the special intermediate application is enlarge, we will adjust it according to the actual situation to change its "identity."
