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.
Two experiments were conducted to test the effect of pelleted foods on the
growth of California white rabbit.
٣٦ weaned rabbits, used in the first experiment, were distributed randomly
and equally inside ٦ boxes. Pelleted and ground foods having t
he same
composition were offered simultanously to be eaten ad libitum for ٢٥ days.
Another ٢٤ weened rabbits, used in the second experiment, were also divided
randomly and equally into two groups. Pelleted and ground foods were offered
to the first and second group respictively to be eaten ad libitum for ٢٥ days.
