Abstract EN
Twenty karadi lambs 6 month old with average body weight 32.2 kg were divided randomly into four groups each of 5 lambs, to study the effect of protein restriction on nutrients digestibility, nitrogen balance and some rumen parameters.
The first group (control) was fed ad-libitum while the 2nd, 3rd and 4th groups were restricted the feed intake by 10,15and 20 % of ad-libitum feeding .The energy content of the last 3 rations were raised to insure that all the animals ingested the same quantity of energy, but protein intake was restricted.
Each group was fed 10 day as preparation period, then 5 day for faces and urine collection .Sample of rumen liquor was taken on day 16.
Results indicated that restricted dry matter and protein had no significant effect on dry matter, organic matter and Fiber digestibility, while significant p< 0.05 decrease was noted in protein digestibility for the second group 74.55 % as compared with control group 82.90% , and the forth group 82.60%.;while significant improvement p<0.01 in ether extract digestibility was noted as the restriction level increased compared with control group.
However, no significant difference in nitrogen balance was noted between treatments.
However, comparing between PH value before and after feeding, the differences were significant in the 3rd group only p<0.01.Total count of bacteria in rumen liquor before feeding was significant p<0.01 increased as restriction level increased.
Moreover, there was no difference in total count of bacteria after feeding.
