What are the nutrients in pig feed?
In order for pigs to grow quickly and healthily, understanding the nutrients needed by pigs is an indispensable first step. Following is a brief introduction to the nutrients that pigs need.
Water: The growth and development of animals, all metabolic activities are inseparable from water, animals lost 1.2% of body weight that is, a sense of thirst. If you continue to lose 8 to 10% of your body weight, metabolic disorders will occur. Losing 20% ​​of body weight can make the animal dead.
Energy: It is produced by the oxidation of pigs' body through the carbohydrate, fat and protein in the feed. Animals consume energy for life-sustaining activities and production. Energetic substances in the diet are mainly corn and oil.
Protein: The amino acid also comes down to this class. In general, the protein we talk about mainly refers to crude protein, and protein is made up of amino acids through peptide bonds and space folding. It can be said that protein nutrition is amino acid nutrition, but why should we list them separately? This involves the question of the balance of one amino acid. It's not that the higher the crude protein, the better. The key is to look at the balance of amino acids. This is why fishmeal Reed protein is better than protein in soybean meal. The first limiting amino acid in pigs is lysine.
Fat: The popular point is that fat is the fat (powder) on a pig's body. It is usually located between the skin and lean meat. The main role is heat production for maintenance and production needs.
In feed, fat is added as an energy feed. The main purpose of adding oils and fats to formulated feeds is to increase their energy levels, adding appropriate amounts of granules, and improving palatability and protein consumption. Adding grease to the premix prevents dust formation.
Feed fats are generally: butter, lard, fish oil, soybean oil corn oil and so on.
Minerals: According to how much they are contained in pigs, they can be divided into two major categories: constant elements and trace elements. Constant elements: calcium, phosphorus, potassium, sodium, sulfur, chlorine, magnesium, etc.; must trace elements: copper, iron, zinc, manganese, selenium, iodine, cobalt and so on.
Vitamins, also known as vitamins, are low molecular organic compounds necessary to maintain normal physiological functions in pigs. It has been found that there are thirty to forty kinds, which are divided into two categories: fat-soluble and water-soluble. Fat-soluble vitamins: ADEK; water-soluble vitamins: B and vitamin C.
