Effect of Probiotics and Walking Stress on Some Physiological and Hematological Parameters of Hassani Goats

Evaluation of using some medical herbs seeds as feed supplementation and their effects on the activity of some enzymes and hormones on male Awassi lambs

“…The present results are in agreement with (32) they reported that a significant decreased in the activity of AST enzymes in white Hy-Line breeder roosters groups supplemented by 1 or 2 or 3 kg. rocket seeds/ton of feed as compared to control group.The activity of ALT and ALP enzymes were significantly (P≤0.05) increased , while the activity of AST was decreased mathematically as lambs get older (table 2), this may be due to the stress which caused by consuming the experimental medical herbs seeds (black cumin or fenugreek or rocket ) ,or may be due that the activity of ALT increased as lambs get older because of fast growth of lambs and significantly increased in daily feed intake as animal get older (33),as the results for increasing the nutritional requirements for maintains and growth (11) , which result increasing the digestion and metabolism that happen in animal stomach which result finally increased the activity of serum ALT (34) ,beside that there is appositive relation between digestion and metabolism operation and the activity of ALT (35).The present results are in accordance with those obtained by (36)on Egyptian Barki lambs and (23)on Iraqi Awassi lambs, they found that activity of ALT enzyme was increased significantly as lambs get older. While the reason for significantly increasing the activity of ALP as lambs get older, this may be due to the fast growth of skeleton of lambs and some part of ALP formed from bone tissues (28).The present results are in agreement with (37), who reported that a significant increased in the activity of ALP enzyme on short horn calves as get older.…”
