Black porpoise breeding techniques

As the world's population continues to grow and the per capita cultivated area has continued to shrink, the contradiction between human and animal crops has become increasingly acute. Therefore, it is of great strategic importance to buffer the contradiction between grain and animal husbandry and grain for this purpose. Herbivore black porpoise is a typical grain-saving small livestock. The vast majority of rural grasses are rich in dietary resources. The black porpoises can effectively use local grasses, and the black dolphins are delicious and tasty. They have unique game characteristics, coupled with their moderate individuality and low prices. The consumption heat has been formed in the coastal areas of China and in many large and medium-sized cities. 1 Living habits Black porpoise is native to the mountainous region of Yunnan, China. It belongs to the herbivorous mammals of the mammalian genus Rodents. It is moderate in body size (0.75-1.25 kg). Its limbs are thick and short, the head is obtuse, the kiss is large, and the eyes are short and the ear is short. Longer, its prominent features are black hair, black eyes, black ears, black feet, no tail, and poor jumps. It does not bite or catch people. The black porpoise is mild in temperament, gregarious, and acute in hearing, timid, scared and afraid. Sudden noises can cause black porpoise turmoil and panic. The black porpoise will make different calls in different situations. For example, when the mother dolphins esthetize, the male dolphins will issue a singer's beggar, and when they are hungry, they will hear squeaks when they hear footsteps. 2 Feeding and managing black porpoise is a herbivorous animal. The digestibility of crude fiber is relatively high. All kinds of weeds, vegetable raisins, leaves, melon husks, plant stems and leaves, and straw are all good feeds for them. Such as long-term no supply of wheat or hay and other plants, black dolphins will occur peeling phenomenon, so feeding should pay attention to the proportion of fine material, properly supplemented with a small amount of cereals, wheat, corn and other fine material. There are many kinds of black porpoise feeding methods, which can be adapted to local conditions, such as pool-type breeding, box (cage) raising, and three-dimensional factory farming. When a small amount of farmer can raise cage feeding. The cage can be made of wooden strips, bamboo strips, iron wires, etc. The specifications are 60cm (length), 50cm (width), 40cm (high), and the bottom of the cage is covered with sawdust or hay, which is good for keeping warm and absorbing moisture. The advantage of this feeding method is that it can control breeding, feed, keep clean, and so on. It is advisable to use the ponds under the conditions of cottages and flats, and the larger ones can adopt three-dimensional factory culture. Feed quality is the key to the breeding of black porpoises, and the focus of feeding and management. First of all, it is necessary to prevent mildew and deterioration of the feed, and it is advisable to feed the feed. When you feed, you should put clean water for drinking and eat small meals. The daily feed intake was about 150g per adult black porpoise, which was fed once every morning and evening to keep the trough clean. Second, we must prevent rodents and snakes from entering the breeding grounds. The rat snake not only contaminates the feed but also swallows black dolphins, causing unnecessary losses. 3 Breeding black porpoises are sexually mature and can be bred and mated at 60 days after birth. They produce 5-6 fetuses per year, have 5-9 litters, and can reproduce 40-60 cubs per year. Breeding should be selected full body, bone thick, bright eyes, hair color light, soft and elastic skin, sexual dolphins do normal development of mating. The duration of estrus in female dolphins is l-18h. After mating, there is a rubber-like embolism and secretory mixture in the vagina of the mother dolphins. According to the presence or absence of embolism, whether the black dolphins can mate is successful. Under normal circumstances, the breeding of the original species uses a male-male mating method. In large herds, two to three female dolphins are used, and one male dolphin is used for mating, but care must be taken not to put more than two male dolphins at the same time. Otherwise, fighting will be affected and mating will be affected. Female dolphins are about gestational for about 68 days and can produce 1-6 calves. Female dolphins are fed separately after weaning for 15 days. The female dolphin can be bred after weaning, and mating of the female dolphin during the latter half of the day can increase the success rate and reproduction rate. 4 Precautions 4.1 At present, most of the black dolphins are bred with sales dolphins, and the processing level is very low. Most units use high-cost recovery methods to induce farmers to introduce species. Therefore, farmers should first find out the species sources before introduction. , to a farmer with a certain scale and technical strength to purchase, and ask for detailed information on the file, pedigree, etc. 4.2 Feeding management is the key to raising black porpoise. The breeding room should always be kept quiet, dry, warm in winter and cool in summer. The room temperature should be kept at 18°C-25°C and the relative humidity should be 45%-55%. Therefore, the breeder must be responsible and responsible for observing and finding problems in time. 4.3 The artificially cultured black porpoise rarely develops disease under strict conditions of feeding and management. However, if the feed deteriorates, nutrition is incomplete, and management is extensive, it can lead to disease. Common diseases include bloat disease and dry lean disease.
