| Abstract | ||||
| This experiment was carried out on the dry buffaloes selected from the herd of experi mental Farm of Animal Production Department, Assiut University. The animals were devided into two groups according to their milk pro duction of the previous lactation and body weight. The lst group was considered as con trol and fed on energy level of 1.4 x mainte nance; the 2nd one was received energy intake of 1.8 X maintenance during dry period. After parturition, both groups were treated simila rly for the first twenty weeks or lactation period. The energy requirement for milk was calculated according to GHONEIM (1958). Blood samples were taken at 60th, 30th, 15th day pre-parturition, as well as, immediately after parturition 30th, 60th and 90th day of lactation period. The serum glutamic oxalac tic (S-GOT) and glutamic pyruvic transaminases ( S-GPT) and alkaline phosphatase (SAP) were determined. The results could be summarised in the following: - 1- The S.GOT activity ranged from 42.3-48.4 units for control group (A) during the dry period with an average of 44.6+1.3 units. While for the experimental group (B) the corresponding values were 47.1-48.5 and 47.6+0.4 units respectively. * Dept. of Med. & Infections Diseases. Fac.of Vet.Med., Ass.Univ. Assiut Vet. Med. J.

After parturition, the averages were 14.4.42.7 and 14.742.2 units respectively. 3- The SAP values were 27.7.0.8 and 30.1+0.8 write for control and experimental groupe respectively during day period. 4. After partujition and during the lactation period, all enzymes decreased siginifican tly. 5- The high level of feeding intake during the dry period of pregnant baffaloes hed effect on the level of S.GOT, SGPT and SAP acti vities, and this effect wag siginilioant only with S.GOT activity at 5% level. | ||||
