Abstract:
The effects of chromium supplementation to the ration
.on the yield and milk composition of Nubian goats
This experiment was conducted in the department of
animal production of the college of agriculture shambat
.( (SUST ), during the period of ( 18-11-2012 to 4-4-2013
Twelve Nubian goat, which have more than one
production season were selected and accordingly divided in
to three equal groups (A, B, C ) based on their averaged body
.weights
The animals in group A and C were fed with chromium
supplementation added as 1.25 ml g to each supplemented
group according to their averaged body weights , as
.(recommended by (Alltech company, USA
Average ambient temperature in the shed was recorded
.to study it
Effect on the experimental animal body temperature
and hence the effect of chromium supplementation on the
experimental animal body temperature , feed intake and the
.effects on milk yield and composition of the animals
-:The results of this study reflected the following
No significant difference in body temperature
between all the experimental animals was
.rdcorded
