  The elemental analysis of crude extracts derived from selected medicinal plants of Pakistan, including Trichodesma indicum (whole plant), Paeonia emodi (aerial parts), Aconitum laeve (roots) and Sauromatum guttatum (corms, berries and leaves) was carried out using SEM-EDX technique. Various elements such as C, O, Cl and K were present in all tested plants` extracts, Al was observed in P. emodi and A. laeve, S was detected in T. indicum and S. guttatum (corms and leaves) while Mg and P were found only in S. guttatum (corms). The data showed that C was present in highest quantity in T. indicum and S. guttatum (leaves) (>80%) followed by O while in the rest of extracts these two elements were found in approximately equal quantities. The other detected elements were present in comparatively trace amounts. These results were also evaluated in correlations with previously reported biological activities of the tested extracts. This study would provide a new and alterative technique for the standardizations of crude extracts.

  This research was carried out at the Department of Microbiology, University of Agriculture Faisalabad, Pakistan in order to study humoral immune response to Newcastle disease vaccine (Lastoa strain) in broilers. For this purpose, 30-day-old broiler chicks were procured from Olympia chicks. The chicks were divided into three groups containing 10 chicks each. The HI-Ab-titre against ND virus in the control group showed an overall Ab-titre with GMT=3.99.The HI-Ab-response in broilers chicks with single dose of Lastoa vaccine ranged from 1:8 to 1:32.This group showed an overall HI-Ab- titer with GMT=13.931. While the HI-Ab titer against ND virus was found to be in the range of 1:16 to 1:128 in broilers chicks which were vaccinated with the 1st dose of ND virus (LaSota strain) at the age of 2 weeks followed by a booster dose with the same strain at 3 weeks of age. The overall HI-Ab-titre against LaSota strain of ND virus came out to be GMT=55.692. During present investigation a significant increase in HI-Ab-titre (GMT) against ND virus was observed in broilers from single to boostered vaccination group.

  In order to use Shaeffer`s formula for the predication of body weight of slaughtering cattle, one hundred and four cattle, 52 of each male and female was used. Linear body measurements such as length from the point of shoulder to the point of pin bone and hearth girth (around the thoracic cavity just behind the elbow joint were taken with measuring tape just before the slaughter of the animals at the slaughter house of Hyderabad city. According to the formula W = G2 x L / 300. Where, "W" is the live body weight of animal in pounds, "G" is the Heart Girth (in inches) and "L" is the length from the point of shoulder to the point of pin bone (in inches). Finally the body weight was converted from pound to Kg. The mean body weight for Male cattle at the age of 2, 3, 4 and 5 years was 200.95kg (2.66, 298kg) (0.71, 300kg) (12.77, 454.04kg) (11.64 respectively. The mean body weight of Female cattle at the age of 2, 3, 4 and 5 years was 217.09kg (9.48, 266.25kg) (6.62, 313.71kg) (4.91 and 340.05kg (8.72 respectively). The present investigation showed a significant increase in the mean body weight of male and female cattle as the age of the animals advanced. The correlation of body weight with spleen size was also made which shows the increase trend in spleen size as the body weight increase.

  To investigate the effect of feeding urea treated sorghum stover with or without cattle manure on the growth performance of cow calves, the current study was conducted in three phases. In phase-I two stacks of urea treated sorghum stover, 1000kg each, were prepared. One stack was added with 5% of cattle maure as source of urease enzyme. In phase II, a feeding trial was conducted using 9 calves in ithree different groups. Three experimental rations viz., ration I, II and III were prepared and allotted to group A, B and C respectively. Ration I was the control and comprise of 50% utreated sorghum stover and 50% concentrates on dry matter basis. Ration II consisted of equal amounts of urea treated sorghum stover and concentrate only dry matter basis while ration III had half the dry matter from urea treated sorghum stover with added cattle manure and the rest from concentrates. In the third phase the digestion trial was carried out from the last 10 days. The dry matter intake was different (P<0.01) among the groups. Average weigh gain of calves in group A, B and C were 33.47, 30.42 and 37.68kg, respectively and were not affected (<0.05) by the ration. The average feed efficiency values for calves fed ration-I, ration-II and ration-III were 7.03, 6.17 and 5.33, respectively and were not different (P<0.05). However the digestion trial showed a higher digestibility for ration-III, followed by ration-II for dry matter, organic matter, crude protein, crude fiber, either extract and nitrogen free extract. The present study indicates that added cattle manure had a positive effect on the overall digestibility of sorghum stover.

  The present study showed the Sero-surveillance of Hemorrhagic septicemia in cattle and buffalo in Malakand division of NWFP, Pakistan. The average GMT was recorded against hemorrhagic septicemia in buffaloes in the range of 4.12 to 46.98, while those in cattle were recorded in the range of 4.45 to 46.40. In young buffalo calves, incidence rate, mortality and morbidity rate was observed as 22.25, 21.19 and 95.25%, respectively. In adult buffalo morbidity, mortality and case fatality rate was 5.49, 1.65 and 30%, respectively. In study of young cattle calves morbidity, mortality and case fatality was recorded as 3.94, 1.77 and 45%, respectively. While in study of adult cattle, morbidity, mortality and case fatality rates were recorded as 2.51, 0.39 and 15.79%, respectively. During present investigation the incidence rate, mortality and case fatality due to Hemorrhagic septicemia was found greater in the young calves as compared to the adult in both buffalo and cattle.

  The present study was conducted to investigate the effect of L-ascorbic acid (AsA) on Nile Ravi buffalo oocytes. Cumulus Enclosed Oocytes (CEOs) and Cumulus Denuded Oocytes (CDOs) were cultured for 24 h in TCM-199 supplemented with Recombinant Human Follicular Stimulating Hormone (RhFSH), 0.4% Bovine Serum Albumin (BSA), oestradiol and Gentamycin. Nili Ravi buffalo oocytes with or free from cumulus cells were exposed to 250 μM AsA. Meiotic maturation, degeneration of oocytes was assessed at different maturation time (0, 12, 24 h). CDOs treated with L-ascorbic acid resumed meiosis and oocytes were significantly (p<0.05) increased to MII stage. Where as CDOs matured in control medium with out L-ascorbic acid supplementation did not show any significant increase in MII oocytes proportion as the maturation time was extended to 24 h (p<0.05). In present study it was observed that cumulus cells are involved in protection against degeneration as CEOs treated in control medium the degenerated oocytes high significantly (p<0.05) decreased to 7.40% as compared to CDOs in which 21.4% oocytes were found to be degenerated. These results indicate that exposure to L-ascorbic acid promote the development of the Nili Ravi buffalo CDOs and cumulus cells are involved in protection against degeneration of oocytes.
