Effect of raising dietary protein, amino acids and/or energy levels as an attempt to alleviate severity of the chronic aflatoxicosis by broiler chicks

This is the authors' abstract. We don't add key points for this paper.

Afiatoxin caused some reduction in moisture contents of chest and liver, lipids of thigh and blood, blood glucose, muscular protein and GOT in liver. It led also to increase of moisture contents of thigh and kidneys; chest lipids; blood cholesterol; protein of liver, kidneys and blood and blood creatinine. The different supplements used herein led to increasing moisture of muscles, liver and kidneys (except on oil addition); lipids of muscles (except of chest on high energy diet) and blood (except on amino acids‐supplemented diet); blood cholesterol (except on high energy one); protein of thigh (except on high protein one) and blood (except on high energy or amino acids diets) and liver GPT (except on high energy diet). The additives led also to low blood glucose; protein of chest (except on high energy), liver, and kidneys; blood creatinine; liver GOT (particularly with high energy or amino acids); plasma GOT (on high amino acids) and plasma GPT. The 2‐week withdrawal period led to low moisture contents of muscles and kidneys of most treatments, although they continued higher than in the control for chest, liver and kidneys. It increased blood glucose and cholesterol with continuous higher lipid content of muscles and blood and blood cholesterol than in the control. It led to elevated protein content of muscles, liver (except on the control or supplements mixture), kidneys (on the aflatoxin alone or with the amino acids) and blood (except on the control or afiatoxin alone or with high protein) and blood creatinine (except on the control or on the high energy or the supplements mixture). It increased the total proteins in all treatments than in the control (except muscular proteins on supplements mixture and liver protein on high energy) and also blood creatinine (except on high energy or supplements mixture). Thus, this period was not enough for complete recovery of kidney disturbances. Values of either hepatic transaminases presented nearly no differences among treatments.
