(Summary description)1. The classification and function of amino acids?   Amino acids are the basic units of protein, which are divided into two categories: essential and non-essential. Essential amino acids refer to pigs that cannot be synthesized or synthesized at a slow rate, which cannot meet the needs of pigs and must be supplied by feed. There are 10 essential amino acids required by pigs, namely lysine, methionine, tryptophan, arginine, threonine, valine, histidine, leucine, isoleucine, and phenylalanine. At present, lysine, egg + cystine, threonine, and tryptophan are relatively lacking in the diet composed of feed ingredients in my country, which reduces the utilization rate of feed and the production performance of animals. Therefore, it should be adjusted according to the type of diet.

1. The classification and function of amino acids?

Amino acids are the basic units of protein, which are divided into essential and non-essential categories. Essential amino acids refer to pigs that cannot be synthesized or synthesized at a slow rate, which cannot meet the needs of pigs and must be supplied by feed. There are 10 essential amino acids required by pigs, namely lysine, methionine, tryptophan, arginine, threonine, valine, histidine, leucine, isoleucine, and phenylalanine. At present, lysine, egg + cystine, threonine, and tryptophan are relatively lacking in the diet composed of feed ingredients in China, which reduces the utilization rate of feed and the production performance of animals. Therefore, it should be used in feed according to the type of diet. Add amino acids appropriately.

2, what is the effect of protein on pigs?

Protein is a class of compounds composed of amino acids. The content and utilization of essential amino acids determine its nutritional value. Protein is the basic component that constitutes the body tissue and somatic cells of pigs. If the protein content in the diet cannot meet the needs of the pig, the growth of the pig will be restricted, the weight will decrease, the feed utilization rate will be reduced, and the reproductive function will be disordered.

3. What is the effect of energy on pigs?

Energy mainly comes from starch, sugar and fat in the feed. Fiber can also provide a small amount of energy. After the pig eats the feed, the above-mentioned substances are converted into energy to meet the needs of maintenance and growth. Starch, sugar and fat are easy to digest and absorb, and produce high calories. Crude fiber is difficult to digest and provides less energy, but it has the effect of making animals feel full and promoting intestinal peristalsis. The fiber content in the feed is different from pigs. There are differences in physiological stages. When the energy in the feed cannot meet the needs of the pigs, the utilization rate of protein will be reduced, the pigs will lose weight, and normal growth and reproduction will be affected.

4. What are the effects of vitamins on pigs?

Vitamins are organic compounds necessary to promote the metabolism of protein, carbohydrates and fats and maintain the health, normal growth and reproduction of pigs. Divided into fat-soluble vitamins and water-soluble vitamins, fat-soluble vitamins include A, D, E, K, water-soluble vitamins include B vitamins and vitamin C. Lack of vitamins in the diet can cause abnormal growth, slow growth, weakened disease resistance and reproductive performance of pigs.

5. Classification of minerals and their functions?

Minerals are divided into macro mineral elements and trace mineral elements. Macro mineral elements include calcium, phosphorus, sodium, potassium, magnesium, chlorine, and sulfur; trace mineral elements include copper, iron, zinc, manganese, etc., and mineral elements are Blood and nutrients necessary to maintain normal growth and reproduction.

6. What is the effect of water on pigs?

Water has the role of participating in the formation, dissolution and transportation of nutrients in the body's cells and tissues. If the water supply is insufficient, it will seriously affect the feeding and metabolism of the pigs. If there is no water supply, it can cause death within a few days.

7. What is the importance of water quality?

Water quality problems are mainly related to microbial contamination and the content of toxic substances, nitrite. The content of microorganisms per liter of water is less than 10 colony units is acceptable for animals, and the content of more than 50 colony units may be harmful to animals and requires treatment; nitrate in water can be converted into nitrite to produce toxicity, nitrite in water The concentration below 100ppm is safe, but when the nitrite concentration in the water is higher than 100ppm, hemoglobin can be converted into methemoglobin. The methemoglobin in the blood cannot transport sufficient oxygen to the tissue. If the methemoglobin content in the blood is too high, May cause death of pigs.

8. What minerals can water provide, and what effect do they have on the growth of pigs?

Common mineral elements in groundwater are iron, sulfur, chlorine and magnesium. These minerals can form complexes with calcium, magnesium, sodium, etc. to form the total soluble matter in the water. According to reports, when the total soluble matter in the water exceeds 5 g/L, it will cause pig diarrhea, affect production performance, and reduce the pig's exercise capacity.

9. What is the importance of dietary energy protein (lysine) ratio?

Pigs usually eat to meet their energy needs. When the energy content of the diet increases, the feed intake will decrease, and the intake of other nutrients will decrease. Therefore, when the feed intake decreases due to increased energy, it is necessary to maintain the energy-to-protein (lysine) ratio, and the concentration of other nutrients in the diet must also be adjusted higher.

10. What is the importance of the calcium to phosphorus ratio in the diet?

The proper ratio of calcium to phosphorus in the diet is very important for their absorption and utilization. The inappropriate ratio of calcium to phosphorus will reduce their absorption rate and slow down the growth rate and bone calcification. When using a grain-soybean meal type diet.
