(1) Breeding males of the breeding period are required to receive 1 to 2 matings and 1 to 2 trials for 1 day during the entire breeding period; 6 to 10 of 3 to 5 females are to be completed throughout the whole breeding period. Subsequent successful mating; due to a large increase in libido impulse activity, a large amount of nutrient consumption; and due to sexual excitement decreased appetite, weight loss. Therefore, during the breeding period, it is necessary to strengthen the nutrition of the species, especially the species of public animals, and take special care and care.
During the breeding period, the full-price protein and vitamin A, vitamin D, vitamin E and B vitamins should be provided. To properly increase the proportion of animal feed. The amount of food given is 500 to 600 grams and it is fed twice daily. In order to maintain the libido and breeding ability of the species during the entire breeding period, and maintain good semen quality, ensure the progress of breeding and the quality of breeding, and provide water and supplements to the species at the end of noon. , Mainly from fish, meat, eggs, milk-based feed, as much as possible to do nutritious, strong palatability and easy to digest and absorb, to ensure the health of the male and female parents.
(B) Management of the breeding period
(1) Feeding time should be matched with the release time, and it should not be put in half an hour before and after feeding. In the early stage of breeding, due to the low temperature, the pair can be fed after the first feeding; in the middle and late stages of the breeding, the first feeding and the second feeding can be adopted. Feeding time obedience to the time, in order to fight the breeding progress.
(2) Scientifically develop a breeding plan. The overall breeding plan must be comprehensively planned before the start of breeding, and the improved type should be improved based on the excellent type, and the inbreeding and breeding should be avoided. Every day before the start of the test, according to the condition of the mother's estrus examination in the previous day, the day's mating plan should be established. The principle is to avoid the inbreeding mating, and to match as much as possible the estrus and male and female mate's sexual behavior. The correctness and reasonableness of the planning will enable the successful breeding and high mating success rate. Therefore, it is very important to accurately determine the estrus estrus, to grasp the timing, to place the seeds at the right time, and to correctly formulate breeding programs.
(3) Check the maintenance cage in time to prevent the species from escaping and causing losses. Every time catching lice to check estrus and pairing breeders, they should be bold and careful. They must be stable, quasi-fast and fast. They must both prevent running and prevent bite injuries.
(4) Add mat grass, do a good job in health, prevent diseases. Due to sexual impulses and poor appetite during the breeding period, it is necessary to observe carefully and distribute the disease and disease in the correct district so as to facilitate the timely detection and treatment of the disease and ensure the health of the paralysis.
(5) Ensure drinking water. In addition to adequate drinking water and cleanliness, we must also provide enough drinking water or clean snow in time after catching the lice to check the estrus or putting in the pair.
(6) Keep the market quiet and prohibit outsiders from entering the market to avoid noise and other irritation. Control the release of time, ensure that the species have a good rest, to ensure that the mother's eel normal estrus and timely breeding.
Breeding and management points for breeding period
The breeding season of alfalfa is longer, generally from early February to mid-April, lasting 2 to 3 months, with large differences between individuals. The central task of feeding and management during this period is to enable all females to have heat and timely breeding, and to ensure the quality of mating so that all mothers are pregnant as much as possible. To this end, it is necessary to improve nutrition standards, ensure the promotion of normal estrus and various feeds, and strengthen the various tasks of feeding and management. What is overriding in terms of management is to do a good job of mating, regularly check the female estrus, properly and timely release, observe its mating, semen quality inspections, etc., and carry out breeding and management work around breeding.
