The Effect of Using Methionine Through Weaning Period on Production Standards on Calves

This study was conducted in Tartus cattle station, on 14 Holishtain-Frisian calves at the weaning age (12 weeks) in order to evaluate the effect of Methionine addition on the productive parameters. The calves were divided in three groups, the first one was considered as a control, the second was fed on milk with 0.2% methionine, whereas the third one on milk with 0.4% methionine. The results showed that the Methionine addition to the diet of calves during the weaning period, increased the daily growth rate after weaning, so this increase was 14%. Our results also showed that the addition of Methionine improved the feed conversion ratio after weaning.
