Core tips
As the saying goes: There are donkeys in the sky. Donkey meat is a delicious and nutritious food. Donkey skin is the main raw material for making Ejiao. Donkey industry is a new industry developed in recent years and has broad development prospects. Donkeys have high utilization rate of forage materials, they are not easy to get diseases, they are easy to raise, and they do well in the selection and feeding management of their breeds, so they can get rich economic income.
Breeding and Feeding of Jackass
Feeding and management When cooperating with the male donkey, it is necessary to reduce the proportion of fodder, increase the proportion of concentrates, and control the energy feed, so that the concentrates account for 1/3-1/2 of the total amount in the diet. When the mating task is large, animal and mineral feeds such as eggs, milk, fish meal, stone meal, and calcium dihydrogen phosphate must be added. In order to meet the requirements of semen quality at the time of mating, feeding should be strengthened at 1-1.5 months before the start of breeding to improve feed quality.
General large donkeys in the non-matching period, the daily feeding of grass or high-quality hay 5-6 kilograms, 1.5-2 kilograms of fine material; medium-duty donkey 3-4 kilograms of hay on the day, fine material 1-1.5 kilograms. 1 month before entering the breeding period, start reducing grass and feeding, to meet the breeding standard of diet: large donkeygrass 3.5-4 kilograms, fine material 2.3-3.5 kilograms, of which not less than 25% -30% soybean cake or beans, lack of early spring For high quality hay, 1 kg of carrots or 0.5 kg of barley malt should be replenished each day.
To enhance physical fitness, it is necessary to handle well-balanced and balanced relationships between male nutrition, sports and breeding. The task of breeding can reduce the weight of the exercise and increase the protein feed. If the mating task is light, the exercise can be increased or the fine material can be reduced appropriately to prevent the male donkey from becoming fat. Exercise is generally performed with light exercise or riding. It can also be driven on a rotary exercise rack for 1.5-2 hours. Exercise can improve sperm motility, but 1 hour before and after mating (seizure), to avoid strenuous exercise, with 20 minutes after the match. The male donkey can be used for sports at the other time except for feeding time.
Normal breeding (seed collection) should be done once a day, once a week for a week, and occasionally once a day for two times, with an interval of more than 8 hours. The young male donkey's breeding frequency should be less than that of a young male donkey. In short, the number of breedings depends on the result of the semen quality test. Over-breeding will reduce semen quality, affect fecundity, and cause infertility. It will also shorten the service life of the male donkey.
Supplementing trace elements for growth
The absence of trace elements manganese and zinc in meat donkeys can cause slow growth. The trace element manganese is distributed in all body tissues, mainly in bone, kidney, liver, spleen, pancreas and pituitary. Manganese acts as an enzyme activating factor or component in the metabolism of carbohydrates, lipids, cholesterol, and proteins and participates in the formation of chondroitin sulfate in the bone matrix, and is an essential substance for maintaining the normal metabolic functions of the brain.
Manganese deficiency will grow slowly, it will reduce the intake of food, bone abnormalities, and ataxia. The lack of manganese will also affect the breeding of the donkey, so that the estrus of the female donkey is not obvious and the pregnancy is easy to abortion in the early stage of pregnancy.
The content of manganese in vegetable feedstuffs varies greatly. Green feed and bran contain rich manganese. Gramineous seeds and roots, tuber content is low, animal feed contains very little manganese. Production is often supplemented with manganese sulfate, manganese carbonate and manganese oxide.
Skeletons are the main storage organs for zinc, and the amount of zinc in the coat is also higher. Zinc is involved in the composition of enzymes in the body and has an effect on the formation, storage, and secretion of hormones. Zinc deficiency causes loss of appetite and slow growth. A long-term lack of zinc in the donkey would completely stop the testicular dysplasia and sperm growth, and the female donkey's zinc deficiency rate would be reduced. The plant feed contains more zinc, and the root and stem feed is poor.
Increase feed palatability
There are three types of feeds used to feed the donkey, namely dry powder, wet mix (water 1:1), and thinner. In general, the feed intake of wet mixes is the best, and the worst feed is the worst.
It is better that the granularity of the crushed granularity corn is 0.8-1.5 mm. If it is too coarse, the utilization rate of the feed will decrease, resulting in waste; if it is too fine, it may cause gastrointestinal ulcers for a long time, which is not conducive to health, and at the same time, the palatability of the excessively fine material will also decrease. This will affect feed intake.
The salt requirement for normal growing fat donkeys is 0.3%-0.4%. If the salt content is reduced from 0.3% to 0.2%, the feed intake can be reduced by 20% and the weight gain can be reduced.
The sweetest taste is the sweetest taste of the donkey. The feed contains sweet taste attractants, such as sweeteners and molasses, which can effectively increase the feed intake.
Drinking water is the source of life, and water is also an essential substance for transporting nutrients. In the early days of water shortage, appetite decreased significantly. In particular, it did not like to eat dry powder. With the increase of water loss, appetite may be completely eliminated.
In addition, some diseases such as parasitic diseases, colds, gastroenteritis, etc., changes in the temperature of the donkey's shelter, donkeys during the conversion process, and the circle, refueling and epidemic prevention process will affect the donkey's intake.
Doing prevention and cure of diseases
Meat donkeys are habitually more resistant to crude feeding than horses, cattle, and livestock, and they are also more resistant to disease, but this does not mean that they do not get sick. Especially under intensive farming conditions, we must strictly implement the principle of “combine prevention and prevention, and focus on prevention,†and pay more attention to environmental hygiene to prevent the occurrence of epidemics. Meat donkeys, like Hummers, are prone to infectious anaemia, epistaxis, and tetanus. To effectively raise meat donkeys, the following points should be noted:
1. When the meat donkey is detached from the ring, it should be allowed to drink enough clean water, and it is forbidden to drink contaminated or dirty water.
2. Do a good job in the hygiene of the house. There should be no overnight excrement in the circle, and the food tank and water tank should be regularly cleaned and disinfected. Circles should be built away from villages to prevent infection.
3. When the meat donkey enters or laps each time, especially after the service is over, it must be allowed to make a few tumbling pains (because the donkey is the best way to rest the ungulates) and brush each one by one. , This will not only help the skin clean, but also promote blood circulation, strengthen the physiological function, improve physical health, eliminate fatigue.
4. Always observe during feeding. Once the meat donkey has been found to be uncomfortable or has reduced food performance, it should be treated immediately by the veterinarian. It must not be numbness and delay.
5. The circle of polygamy between mother and mother should pay attention to sexual harassment. Polyculture is prone to mutual biting and colliding, and it also causes accidental trauma, which induces tetanus. If the mother's pregnancy is easy to abortion. Therefore, when setting up the food barrier, the stronger and better it is, which is conducive to large-scale breeding.
Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
