There is a problem that farmers often consider, that is, the formula of daily feed, how to match the sheep feed diet? What are the principles? Recently, many farmers have consulted Xiaobian in the background. Today, Xiaobian introduces the four principles of sheep feed diet.
1 Four principles for sheep feed diet
1.1 Nutritional principles
Sheep feed diets must be based on the nutritional standards of the flock, combined with different production conditions and the growth of the flocks, flexible adjustment of the proportion of age, if the age of nutrition does not reach the flock growth If necessary, you need to adjust the ratio. At the same time, in the sheep feed diet, we must pay attention to feed diversification, ensure that a variety of feeds can be used in a reasonable mix, and give full play to the nutritional value of each feed type to achieve the goal of balanced nutrition. Sheep feed should be scientifically matched with green feed, dry roughage, silage, concentrate and various supplements. Under normal circumstances, the total dry matter ratio of the diet is prepared according to the following formula, the coarse and coarse feed accounts for 50% to 60%, and the concentrate feed accounts for 40% to 50%. In the concentrate, corn and other seeds account for 30% to 50%, and protein feed accounts for 15% to 20%. The rest are minerals, vitamins and various additives.
1.2 Economic principles
The cost of breeding directly determines the breeding efficiency of farmers. Sheep are ruminants, they can eat a lot of green fodder, and then slowly chew and digest the green roughage through ruminant. Therefore, the flock's green roughage sources are more extensive, such as corn stalks, legume straws and peanut stalks. A good source of green roughage. The requirements of the sheep for protein in the diet are not high. In the process of compounding the sheep feed diet, the green roughage should be mainly used to properly supplement some concentrates. The green roughage is mainly based on the wide range of crop straws. The regional sources are relatively wide, and low-cost concentrates such as corn and soybeans are used in conjunction with the diet to better control the cost of feeding and obtain higher economic benefits.
1.3 The principle of palatability
The palatability of the diet has the most direct relationship with the amount of feed and food consumed by the sheep. To ensure that the diet has good palatability, it is the key to eating desire and increasing feed intake. If the palatability of the diet is poor, it will not be able to stimulate the flock's desire to eat, reduce feed intake, and increase the amount of waste in the diet, posing a serious threat to the healthy growth of the flock. For fattening sheep, if the feed quality is poor and the palatability is poor, it will seriously affect the fattening effect of the sheep, which is not conducive to the weight gain of the sheep. Therefore, for some feeds with poor palatability, especially those rough straws that are hard to damage the oral cavity and gastric mucosa of sheep, must be thoroughly smashed, smashed and fed, and a certain amount of seasoning is added to the feed. Improve the palatability of the feed.
1.4 Security Principles
In recent years, as the sheep breeding industry continues to expand towards scale and industrialization, and consumers are increasingly demanding green and safe foods, they hope to be able to purchase safe and pollution-free lamb products in the market. During the feeding process, it is necessary to ensure the safety of feeding. This requires a safe work for the sheep feed diet. The feed ingredients must be of high quality and safety, with good texture, non-toxic, harmless and non-polluting. It is forbidden to use moldy and deteriorated feed. In the process of compounding sheep feed diets, it is necessary to control the amount of additives added, to establish safety awareness, to control the use of antibiotics and hormones, and to establish a pollution-free safety awareness, and to eliminate the use of veterinary drugs prohibited by the state.
2 sheep feed diet coordination method
The key to the cooperation of sheep feed diet is to formulate and adjust the diet formula. The formula of sheep feed diet can be formulated by manual calculation or computer formula, but the basic principle is the same regardless of the method used. Based on the nutritional needs of the group, the feed cost is controlled. The dry matter intake of the flock is generally 3% to 4% of its own body weight. Therefore, the feed mix of sheep feed should be controlled within the range of effective feed intake of the flock.
First, according to the feeding standard and the feeding value table, record the main nutrients of various feeds and the corresponding nutrient requirements of the sheep, and make a nutrition demand form. Secondly, according to the production requirements and production experience, set the proportion of the initial mixing of various feed ingredients. Generally only need to consider the crude protein, energy and crude fiber content, other nutrients are temporarily not considered. At the same time, a percentage of dry matter of about 3% should be reserved for the addition of minerals and vitamins. Combine the initial mixing ratio, calculate the content of each difference, compare the cumulative result with the nutritional demand. When a certain indicator has a large difference, the feed ratio should be scientifically adjusted. Finally, when the nutrient meets the nutrient demand of the flock After that, the amount of minerals, vitamins and amino acids added is calculated. 0.5% salt and 1% mineral are generally added to the mixed feed.
