High-yield techniques of raising meat donkey

Variety and fattening

The nutrition needs of different breeds of donkeys are quite different during the fattening period. Generally speaking, donkeys of meat breeds need less nutrients than non-meat breeds to get the same daily gain.

Age and fattening

Donkeys at different growth stages require different levels of nutrition during fattening. Young donkeys are in the stage of vigorous growth and development, and the important parts of weight gain are bones, muscles and viscera, so the protein content in feed should be higher. Fat is the main part of the weight gain of adult donkeys in the fattening stage, when the protein content in the feed is relatively low, while the energy should be higher. The total amount of nutrients needed for weight gain per unit was the least in young donkeys and the most in old donkeys. However, the digestive function of young donkeys is not as perfect as that of old donkeys, so young donkeys have higher requirements for feed quality.

During the fattening period, the weight gain of donkeys is mainly muscle and bone in the early stage, and fat deposition in the later stage, so sufficient protein and proper heat should be supplied in the early fattening period, and sufficient energy should be supplied in the later stage. For donkeys of any age, when fat deposits to a certain extent, their vitality decreases, appetite decreases, feed conversion rate decreases, daily gain decreases, and it is uneconomical to continue fattening. Usually, the younger the age, the longer the fattening period, such as the foal takes more than 1 year. The older the age is, the shorter the fattening period is, for example, the adult donkey only needs 3 ~ 4 months. The length of fattening period is also affected by feed quality and feeding mode, and the feed efficiency of grazing is lower than that of house feeding, so the fattening period of grazing donkey is longer than that of cottage donkey.

Environmental temperature and fattening

Ambient temperature has a great influence on the nutritional requirement and daily gain of fattening donkeys. Donkeys in low temperature environment, in order to resist the cold, need to increase heat production to maintain body temperature, so that a relatively large number of nutrients through metabolism into heat energy and loss, feed utilization rate decreased. In the high temperature environment, the breathing times of the donkey increases, the feed intake decreases, and the high temperature will lead to food stoppage, especially the fat of the donkey in the late fattening period is fatter, and the harm of high temperature is more serious. According to the physiological characteristics of donkey, the suitable temperature is 16 ℃ ~ 24 ℃.

Feed types and Meat quality

Different types of feed will directly affect the quality of donkey meat, feeding regulation is the most important means to improve meat yield and quality. Under the premise of not affecting the donkey's health and digestion, the more nutrients given in the short term, the higher the daily gain, the less feed consumed per kilogram weight gain, the higher the hurdle and the benefit. The nutritional status of donkey in fattening period has a great influence on meat yield and meat quality. only the donkey with good fattening degree has the best meat yield and meat quality. The type of feed has an important influence on the color and taste of meat. The donkey fattened with yellow corn has yellow meat and fat with strong fragrance. Feeding granular hay powder and concentrate can quickly deposit fat in muscle fiber and improve the quality of meat. The conversion efficiency of feed into muscle is much higher than that of feed into fat.

Body weight and feed utilization ratio

The column body is determined by attaching importance to the market demand. The body weight, feed consumption and utilization rate are also different. The general rule is that the greater the weight of the donkey, the lower the feed utilization rate.
