Autumn fattening donkey makes good money

Meat donkeys are an indispensable and important part of maintaining the development of meat donkey farms. The rise and decline of meat donkeys not only affects the development of individual meat donkey breeding farms, but can even affect the fluctuation of the entire industry. Therefore, the meat donkeys must be kept scientifically and regularly.

According to the nutritional needs of breeding meat donkeys, the feed should be arranged with full price nutrition and various combinations. Beef cattle are highly palatable and easy to digest. Fine, coarse and green feeds must be properly matched. Concentrates should focus on proteins with high biological value, and the proportion of concentrates should be about 40% of the total nutritional value, and focus on the following two aspects:

Feed collocation

Succulent feeds and roughages should not be overdosed. Excessive long-term feeding will increase the volume of the digestive organs of the donkey donkeys, creating a “grass-bellied belly” and affecting the efficiency of seed use. Feeds with high carbohydrate content (such as corn) should be fed less, otherwise it is easy to cause the unfavorable consequences of breeding meat donkeys to reduce their fertility. Bean cakes and other protein-rich concentrates are good feeds for meat donkeys, but they are physiologically acidic feeds that feed a lot of organic acids in the body and are detrimental to the formation of sperm. Silage is a physiological alkaline feed, but the silage itself contains a lot of organic acids, too much feeding, the same harmful. Bone meal, salt, and other minerals have a direct relationship with the health of meat donkeys and semen quality. In particular, bone meal (or other feed containing calcium and phosphorus) must be guaranteed. Salt is also important for stimulating digestive function, increasing appetite and normal metabolism, but the amount of feed should not be excessive, otherwise it will have a certain degree of inhibition on the sexual function of the meat donkey.

When the concentrate or multi-meal feed is overdose, resulting in decreased semen quality, an appropriate amount of high-quality hay should be fed on the basis of reducing the amount of concentrate or multi-feed, and after adjustment, the quality of semen can be significantly improved. When the concentrate is too simple and affects the quality of semen, it must be added. The best feed for animal protein additives is eggs, fishmeal and meat donkey milk. This kind of animal feed is indispensable for frequent picking. The meat donkey feeds a large amount of hay and other concentrates for a long period of time, resulting in “grass-bellied”. It is very difficult to correct the feed by adjusting the feed. However, it is difficult to correct the early feeding amount, and the possibility of adjustment and correction may be a problem in this regard. Often occurs in the cultivation phase of small meat donkeys.

Feed amount

The concentrate feed is given 0.4 to 0.6 kg per 100 kg of body weight. The best amount of a donkey donkey should not exceed 8 kilograms per day, generally 5-6 kilograms, but the fine material quality should be excellent. The amount of green roughage fed can range from 1 to 1.5 kg of hay per 100 kg of body weight, 0.6 to 0.8 kg of silage, and 0.8 to 1.0 kg of carrots. The total amount of green roughage is about 10 to 12 kg. Summer feeding mowing (medium quality, mainly grass), weight can be fed to 2 to 3 kg per 100 kg. In addition, each kind of meat donkey can be fed with 0.4 to 0.5 kg of eggs each day, or 2 to 3 kg of meat donkey milk, or 100 to 150 grams of fishmeal, 100 to 150 grams of bone meal per day, and 70 to 80 grams of salt.

Meat donkeys should ensure sufficient drinking water. Before and after mating or harvesting, do not drink water within half an hour before and after exercise, so as not to affect the healthy development of meat donkey breeding, and not to drink dirty sewage and hail water.

Efficient fattening

1. Meat donkey fattening method

According to the fattening intensity of meat donkeys, it can be divided into two methods: continuous fattening and late-stage fattening. The continuous fattening method is a method of fattening the meat donkey immediately after weaning until it is slaughtered (12 to 18 months old, weighing 400 to 500 kg). It can use both grazing and supplemental feeding methods, but it can also be used to feed the quail feeding method. From an economic point of view, the use of grazing and supplementary feeding methods can reduce the consumption of concentrates, have a low fattening cost, and can achieve higher weight gain. If there is no grazing condition, complete use of refined fattening, in terms of feed conversion, is not economical and costly. The latter-stage concentrated fattening method, also known as intensity fattening or fast fattening, is an example of such fattening methods. The specific approach is to suffocate shelf donkeys who are not enough to slaughter their body weight in 1 to 3 years, and feed more concentrates in a shorter period of time (generally 90 to 120 days) to allow them to increase their weight and achieve market weight. This method can not only improve the quality of meat donkeys, increase the product rate of meat donkeys, reduce consumption of concentrates, and reduce costs, but also increase the number of capital turnover, increase the utilization rate of livestock houses, and increase economic efficiency. This is the most adopted method for many meat donkeys in China. The kind of fattening method used by donkey households should be comprehensively considered according to their own housing, feed, funds, and sales.

2. Properly allocate feed to meet the nutritional needs of meat donkeys

Fattening donkey diet composition, including roughage, concentrate feed, and additive feed. Meat donkey straw roughage should be crushed and aminated. The concentrate feed can be prepared by corn, sorghum coarse grinding, and bran, cakes, and calcium bicarbonate. A vessel of cereals accounted for 70% to 80%, bran 10%, cakes 10% to 20%, minerals 1%, and sodium bicarbonate, salt, trace elements, vitamins and enzyme preparations were added in proportion. If the roughage in the diet is not ammoniated straw, but hay, silage or distiller's grains, then 80-100 grams of urea can be fed per head per day, and the fine material (from less to more) can be evenly mixed with the coarse material. Summer feeding In order to reduce the heat stress of meat donkeys, the nutrient concentration in the diet should be appropriately increased, especially the protein content, and additives such as sodium bicarbonate with cooling effect should be added. In winter, it is necessary to increase the energy level and increase the supply of concentrate to ensure various nutritional balances.
