Publisher: 1994Dissertation note: Nih Ravi is the well established breed of buffalo in Punjab. There are about 140 million buffaloes in the World out of which the largest buffalo population is in India, China and Pakistan. It is a multipurpose animal and fulfils milk and meat demand of mankind. In Pakistan it contributes about 74% of total milk yield. The annual rate of increase in buffalo population is 2.5% and increase in milk production is 3.5% in India and Pakistan. To fulfil the increasing demand of milk and meat, there is an immense need to improve the health status and production potentials of dairy animals. This can he achieved only if we are abreast with physiological norms, the disturbance of which lowers productivity. There are numerous problems of health, reproduction and milk production of Nih Ravi buffalo. Despite this very little information is available on blood chemistry of buffalo belonging to different agro-clirnatic conditions. There are various factors which play important role in their rate of production and minerals are one of those factors. Imbalances of minerals, produces deterimental effect on the performance of livestock e.g. Mineral imbalances lead to syndromes manifested in form of retarded growth, low production, late maturity, wasting disease, non infectious abortion, infertility, silent heat, retained placenta, dystokia and prolapse of vagina and uterus. To cope with the situation more research is required on the subject to locate the extent of mineral imbalances. The conclusive results will produce direct or indirect effect on the production and reproductive performance of livestock. The study is therefore planned to find out the serum mineral profile of lactating and non lactating buffaloes from different areas of Punjab and the effect of stage and number of lactation on mineral profile and to find the correlation of serum mineral profile with prolapse of vagina and uterus.
To determine the mineral profile in lactating and non lactating Nih Ravi buffaloes 200 blood samples were collected from Okara, Jhelum and Lahore/Sheikhupura. The serum was separated from blood by centrifugation. Serum was analyzed for sodium, potassium, chloride, calcium, magnesium, phosphorus and iron on spectrophotometer. The data thus obtained was subjected to statistical analysis by using analysis of variance and the differences in means were tested by using (L.S.D. test) least significant diference test.
The mean values of serum mineral in lactating and non lactating buffaloes on overall basis were subjected to statistical analysis and found non significant differences. However serum magnesium levels were found to be significant in lactating and non lactating buffaloes.
The means values of serum minerals in buffaloes of various districts were subjected to statistical analysis by using analysis of variance and L.S.D. test and significant differences were found between districts (P <0.05) for sodium, potassium, magnesium, phosphorus and iron, while non significant differences were found for calcium and chloride (P>0.05).
The mean values of serum mineral in lactating and non lactating buffaloes on the basis of lactation number were subjected to analysis of variance and L.S.D. test and found non significant differences for serum sodium, potassium, chloride, calcium, magnesium and iron, while serum phosphorus showed singificant differences on the basis of lactation numbers and stage of lactations.
The differences in the mean values of serum sodium, potassium, chloride, magnesium and phosphorus were found to be significant. While calcium and iron showed non significant differences within distircts.
The serum sodium showed deficiency in Lahore/Sheikhupura district while serum potassium, chloride, calcium, magnesium and iron values were found in normal range in all districts. However serum phosphorus level were slightly higher in buffaloes of all the districts.

Publisher: 2014Dissertation note: The snake venom has both neurotoxic and haemotoxic effects. The Pakistani spectacled black cobra venom is considered to be mainly neurotoxin and there is a need to evaluate its haemotoxic effects. This study aimed to determine the acute bio-physiological effects of LD50 dose of crude venom of cobraat different time intervals after I/M envenomation in mice.
The crude venom was obtained from the black cobra, Naja Naja karachensis found in the region of Mian Chanuu, Punjab and the venom was lyophilized. Twenty adult male mice, approximately 20g weight, were housed in cages for one week at the animal shed of University of Veterinary and Animal Sciences, Lahore. Blood was drawn by cardiac puncture after general anesthesia at time 0 from the five overnight-nonfed mice injected i/m with normal saline. Remaining mice (15 in number) were injected i/m with LD50 dose (1.2mg/kg) of cobra venom. Blood samples were collected from five animals at each time intervals of 1, 1.5 and 2 hours of envenomation. The hematological and biochemical parameters studied were complete blood count, estimation of plasma glucose, plasma total protein, plasma albumin, alanine aminotranferase and urea by commercially available enzymatic kits.
There was a significant increase in red blood cells count and its indices (haemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration) and platelets at 1, 1.5 and 2 hours after envenomation in albino mice compared to 0 hr.A significant decrease in the count of white blood cells was observedafter 1 hour of injection compared to 0 hr, however it was increased significantly after
2 hours of envenomation compared to 0 hour. The lymphocytes, monocytes and granulocytes percentageswere not changed after envenomation in mice.Plasma glucose showed a significant decrease at 1 hour of I/M injection compared to 0 hr that increased in subsequent time intervals compared to 0 hr in albino mice. The concentration of urea was significantly increased at 1, 1.5 and 2hours of envenomation in comparison with the concentration at 0 hour. The concentration of plasma total proteins showed a significant increase at 2hours of time interval as compared to 0, 1 and 1.5hours after envenomation in mice. The plasma albumin concentration at 1.5 and 2hours of time interval showed a significant increase as compared to that at 0 and 1 hour. The concentration of ALT also increased at any time interval.
Therefore it is concluded that the crude spectacled cobra venom is both neurotoxin and hemotoxic in nature.
