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.
This experiment is done on (24) male awassi lamb whish are
divided into four categories: the first category took normal water
and is considered as control group. The other three groups took
water processed with different Magnetic Field : 500, 1500, 2000
**Gauss in a series.
This research aimed to study the effect of adding different rates of lysine on the weight and
growth of common carp fingerlings. The experiment was carried out in the laboratory for 4
months using eight glass containers (40 liters each) with four t
reatments (L0 no Lysine
addition, L1 (2%), L2 (3%), L3(4%) of the total weight of diet. Eight common carp
fingerlings (average of tall 7.5cm ± 0.05 and average of weight 12.25g ± 0.57) were
cultured in each container with Oxygen pumps and filters.
Results showed by growth rate, absolute growth rate, specific growth rate and food
conversion ratio (FCR) that the treatment L1 (2% lysine) was significantly the best
comparing to the other treatments, where FCR was (2.2) and the specific growth ratio was
(0.28 %)
