Description
Rengeerli Sa and co-authors test amino acid balance in low protein diets for Tibetan sheep in this paper, published in 2024. Lysine and methionine are limiting amino acids for fat and growth. Their ratio may matter more than total protein. Ninety healthy male sheep were split into three diet groups with ratios of one, two, and three to one.
Back fat was profiled with detailed lipidomics. Gene activity for fat building, antioxidant defense, and fat breakdown was also measured. The one to one group showed the strongest antioxidant capacity. Its fat cells were more orderly and uniform in size. Unsaturated fatty acids rose broadly in that group. Several lipid molecules tracked closely with the better profile. Balanced amino acids may offset a low protein diet.
