Pig material becomes the main growth point of methionine in the future

methionine affects the reduction of pig muscle weight methionine intake will affect the growth performance of pigs and cause economic losses
uYNmethionine not only can carry out protein synthesis, but also has cell information transmission, gene expression, antioxidant effect and immune regulation;uYN
Pigs fed normal daily grains weighed 11.6 kg less than pigs fed 10% less methionine, and pigs that weighed 10% less on methionine weighed 9.9kg, of which muscle weight was 25% heavier than pigs fed 10% less methionineuYN
Intestinal metabolism affects essential amino acidsuYNintestinal epithelial is the body's first line of defense, the intestine is the first use of amino acids and other nutrients of the organ, more than 60% of the nutrients in which the decomposition of energy, the remaining less than 20% for protein synthesis; The need for amino acids in different animals from coarse protein levels to standard intestinal digestible amino acid levels has been studied, and a large number of experiments have shown that, due to the breakdown of intestinal metabolism, if intravenous sulfur-containing amino acids are used, the demand for piglets can be reduced by about 50%uYN
The internal organs of the body first use amino acids, if the intake of methionine is limited, the relative weight of visceral tissue and weight will not decrease, but will significantly reduce the relative weight of the longback muscleuYN
The messenger RNA expression of GLP-2R and e-NOS prompted methionine hydroxyl analogue analogue to increase the flow of blood in the door vein, while the increase in the blood flow of the door vein significantly increased the amino acid content of the necessary and conditional amino acids in the door vein (significantly more significant for arginine, ialetine, leucininand and histine)uYN
The amino acid composition that affects muscle protein growth after the first metabolism of the intestine is an effective way to reduce the effect of intestinal first metabolism on essential amino acidsuYNdifferent methionine sources on lactating sows and piglets
uYNexperiments show that different methionine sources have no effect on sow weight and back thickness, by adding methionine hydroxyarise analogue to improve the level of total sulfur-containing amino acids in the diet, can increase the pig's milk Protein, fat and lactose content can effectively improve the content of taurine and cysteine in pig milk, due to higher quality breast milk and better absorption of the intestines, the pythnonine hydroxyl analogue in the 14-day age of piglets at 14 days of age weight weight 1 kg heavier than the control groupOn the 21-35-day-old piglet's body weight gain also had a significant effect, not related to weaning the age of dayuYNmethionine affects the growth performance of pigs and causes economic losses
