The best formula of sheep feed

In sheep breeding, feed selection and formula are very important. In order to get sheep out of the fence as early as possible, feed should be scientifically proportioned to meet the needs of sheep growth. At the same time, in order to make rational use of all kinds of feed raw materials and improve the utilization rate of feed nutrients, it is necessary to match all kinds of feed reasonably. Let's take a look at the best formula of sheep feed.

The best formula of sheep feed

1. The formula of house feeding fattening concentrate: 21.5% corn meal, 21.5% grass meal, 21.5% bean cake, 17% corn kernels, 10.3% peanut cake, 6.9% wheat bran, 0.7% salt, 0.3% urea and 0.3% additives.

2. Grazing supplementary feed formula: corn 30%, wheat bran 25%, rapeseed cake 20%, barley 20%, minerals 3%, salt 2%.

3. Lamb mixed concentrate formula: corn 60%, bean cake 9.5%, flax cake 10%, wheat bran 20%, bone meal 0.5%.

Nutritional composition of Sheep Feed

1. Vitamins: the main function is to regulate physiological function, maintain health and prevent diseases. There are four kinds of fat-soluble vitamins: VA, VD, VE and VK. Water-soluble vitamins include B vitamins, VC, VP and so on. Sheep can synthesize a certain amount of B vitamins through rumen microorganisms, which are rich in VD, VE and VK in general feed, and VA is the most easy to lack. Therefore, special attention should be paid to the supplement of VA in the process of feeding mutton sheep.

2. Energy materials: carbohydrates are the main energy substances. The energy needs of sheep are related to the activity procedure. Sheep grazing on the prairie consume 10-100% more energy than those fed in captivity.

3. Protein: in the process of sheep metabolism, it is necessary to absorb protein from all kinds of forage. As the structural material and renewal material of all kinds of body tissue, the need of protein is actually the need for amino acids and the diversification of forage feed. it is helpful to ensure the full price of protein nutrition.

4. Minerals: they are the main components of sheep bones and teeth, and the major elements are calcium, phosphorus, sodium, potassium, chlorine, magnesium, sulfur and so on. The main trace elements are iron, copper, zinc, selenium, iodine, cobalt, molybdenum and so on. They play a very important role in the digestion, absorption, metabolism, acid-base balance, maintenance of osmotic pressure and composition of animal body.

Formula calculation of Sheep Feed

1. The average body weight and daily gain of + sheep in house feeding flock were determined as the basic basis of dietary formula.

2. The nutrient content per kilogram of diet is calculated. The nutrient requirement of sheep is divided by the feed intake of sheep (%), such as 15% of crude protein, 8.2 megajoules / kg of energy, 0.8% of calcium and 0.4% of phosphorus.

3. Determine the feed to be used, list the nutritional composition and nutritional value table of the selected feed, in order to select and calculate.

4. give priority to the content of energy and protein in the diet, set aside the share of minerals and additives, generally 2% to 3%, and try to prepare a preliminary mixed feed.

5. On the premise of keeping the energy concentration and protein content of the initial mixture basically unchanged, adjust the amount of feed raw materials to reduce the dietary cost and keep the two basic nutritional indexes of energy and protein in line with the needs.

6. on the basis of energy and protein content and feed matching basically meet the requirements, adjust the supplement of calcium, phosphorus and salt as well as additives and other indicators.
