Clear the nutrient components of sheep feed
1. Vitamin: Its main function is to regulate physiological functions, maintain health and prevent diseases. Water-soluble vitamins include B vitamins, VC, VP, etc. Sheep can synthesize a certain amount of B vitamins through rumen microorganisms, and the most lacking substance is VA, so special attention should be paid to the supplement of VA in the process of feeding mutton sheep.
2. Energy substances: carbohydrates are the main energy substances. Sheep's energy demand is related to activity program. Generally speaking, grazing sheep consumes 10- 100% more energy than feeding sheep in houses.
3. protein: In the process of metabolism, sheep need to absorb protein from all kinds of forage they eat. As the structural material of various activities, protein's demand is actually the demand for amino acids. Diversification of sheep feed is beneficial to ensure the nutrition supply in protein.
4. Minerals: they are the main components of sheep bones and teeth, and play an extremely important role in animal digestion and absorption, metabolism, acid-base balance and body maintenance.
After knowing the nutritional components of sheep tissues, it is necessary to calculate the formula of sheep feed.
1. After determining the feed raw materials used, list the nutritional components and nutritional value table of the feed used for selection and calculation;
2. Determine the average weight and daily gain level of+sheep in the house-feeding flock as the basic basis of the diet formula.
3. Calculate the nutrient content per kilogram of feed, divide the nutrient requirement of sheep by the feed intake of sheep, and get the nutrient content per kilogram of feed (%), such as crude protein content 15%, energy 8.2MJ/ kg, calcium 0.8% and phosphorus 0.4%.
4. Give priority to the energy and protein content in the diet, set aside the share of minerals and additives, generally 2-3%, and try to make a preliminary compound feed.
5. On the premise that it is inconvenient to keep the mixture concentration and protein content, adjust the materials of feed raw materials to reduce the cost of diet and keep the balance between energy and basic nutrition in protein.
Remind attention to other indicators such as calcium, phosphorus, salt and additives in feed collocation nutrition indicators to ensure balance.
