A Study On The Chemotherapy And Taxonomy Of Mange Mites In Ovine And Its Effect On Different Blood Parameters
Material type: Book ; Format:
Publisher: 1993 Dissertation note: A study was carried out to find out the taxonomy, chemotherapy of mange mites in sheep and its effect on different blood parameters. A total of 30 flocks comprising of fifteen hundred sheep of different age and sexes were examined in the city and villages around Lahore. Out of above mentioned animals 200 suspected sheep were thoroughly examined and 30 (15%) were found positive for mange mites infestation. Species of three genera namely Sarcoptes, Psoroptes and Chorioptes were found infesting these animals.
The average number of mites recovered from the species of each genera were recorded as 851, 825 and 815 for Psoroptes, Sarcoptes and Chorioptes respectively. For the identification of different species of mange mites microscopic examination was carried out and mites were first seen under low power and then high power of magnification. The slides were mounted with mites and then examined to study their morphological characteristics.
The three genera identified were Sarcoptes, Psoroptes and Chorioptes in sheep.
Chemotherapeutic trials were carried out in suspected sheep by using two concentrations of neguvon solution i.e. 0.10% and 0.15% at ten days intervals. For this purpose sheep were divided into three groups. Group A was treated with 0.10% solution of neguvon, group B with 0.15% solution of neguvon and group C was kept as untreated control group. The data obtained on reduction of mites due to acaricide application were subjected to statistical analysis by applying completely randomized design and results were recorded. It was noticed that 0.15% neguvon was highly effective against mange mites infestation when it was replied twice after ten days interval.
The effect of mange mites on different blood parameters was also recorded. For this purpose sheep were divided into three groups. Group I comprised of clinically infested sheep, group II subclinically infested sheep and group C included healthy sheep which was kept as control for the comparison. The effect of mange mites on different blood parameters of two infested groups of sheep i.e. I and II was recorded before and after two applications of 0.10% and 0.15% neguvon solution at ten days interval and results were compared with group C for comparison.
The findings of this study indicated that the infestation of mange mites is a quite common problem in sheep population of this area. The sheep suffering from mange mites exhibit poor feed intake, severe irritation, scratching, bleeding, loss of wool, low body growth, reduced production and damaged skin. Such infested sheep are also susceptible to various viral and bacterial diseases which makes sheep production uneconomical and put extra burden on the sheep breeders.
Keeping all this in view suitable and prompt measures should be taken for early diagnosis and treatment of the infested animals. This will result not only for the control of the disease, but also help to improve the economical condition of the owners. It will also increase the gross national product of Pakistan.

Comparision Of Mineral Profile In Lactating And Non-Lactating Nilli-Ravi Buffalo
Material type: Book ; Format:
Publisher: 1994 Dissertation 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.
