Effects of glycine and glutamic acid supplementation to low protein diets on performance, thyroid function and fat deposition in

  • 2010
  • Issue: 3
  • Volume: 40
N.F. Namroud, M. Shivazad, M. Zaghari and A. Zare Shahneh Page: 238 - 244

Consumption of low crude protein (CP) diets causes elevation in fat accumulation in chickens, and this effect is independent of dietary essential amino acid levels. Thyroid hormones, because of their metabolic regulatory characteristics, might be an effective factor in lipogenesis.…
