[Effect of varying amounts of lysine in the ration on chickens]

The effect of varying lysine quantities given in the daily ration to 20 day-old chickens was studied for a 40 day-period. Highest body gain (157% as compared to the control group) was observed in group I (0.20% lysine). Two and four per cent of lysine in the ration reduced the basic body gain by 69.7% and 66.9% respectively. The level of calcium, blood sugar, carotene and vitamin A rose considerably, while phosphorus and magnesium content was reduced. SGOT and SGTP values remained without significant changes. The relative kidney weight increased.
