STUDY ON THE ISOLATION AND IDENTIFICATION OF ASCARIS LUMBRICOIDES FROM SINDH, PAKISTAN

 

           

Ascaris lumbricoides is an intestinal parasitic nematode that causes the intestinal disease in animals. Due to its severe infection, their reproduction and production process becomes decreased. Therefore, the present study was conducted for isolation and identification of Ascaris from contaminated soil of 5 different locations namely two from SAU area, Jam Bungalows, Mir Colony and village Sultan Magsi, near Tandojam town .One hundred samples were collected from all the five locations (20 from each location) and contamination of soil samples were determined. The results revealed that out of 20 soil samples, each from Jam Bungalows and Mir Colony area of Tandojam where the 15 samples were found positive showing 75% contamination of soil by the Ascaris eggs while, 20 sample were collected from Animals farm at Department of Animal Reproduction (SAU) where the 11 found positive those showed 55% soil contamination of the Ascaris eggs. While, 20 samples collected from Livestock Experimental station Farm (SAU) and dry area of village Sultan Mangsi in which 9 were found positive those showed 45% with Ascaris eggs contamination. It was concluded that all the samples which were taken from each location were found to be contaminated with the density of Ascaris eggs contamination.

Histochemical studies on Delonix elata (L.) Gamble. (Cesalpiniaceae) Leaves.

 

           

The histochemical studies of the Delonix elata of the leaflet were investigated to certain the relevance of these characters in establishment of interspecific similarities and differences in these taxa. The results showed that leaflet is thin with fairly prominent lateral vein and midrib. The lamina is 110 mm thick, the lateral vein is 170mm thick and the midrib is 180 mm thick. Adaxial epidermis 10-20 mm thick. Adaxial groove, it is 1 mm thick. The outer ground tissue is narrow while the central ground tissue is wide and parenchymatous.

Effects of Synthetic Ascorbic Acid and Baobab Fruit Pulp Meal Supplementation as Sources of Ascorbic Acid for layer Diets During Cool-Wet Season –(Sub theme Livestock improvement, health and management).

 

           

An experiment was carried out to study the effects of ascorbic acid (AA) and dietary levels of dried baobab fruit pulp meal (BFPM) supplementation as sources of ascorbic acid in layer diets during the cool-wet season. The results for feeding trials indicated that ascorbic acid supplementation up to 200mg/kg of diet and 3.5% dietary level of Baobab fruit pulp meal significantly improved performances of layers . Ascorbic acid supplementation of 200mg/kg also improved the performance of laying hen compared to the control diets as reflected in improved final weights, hen-day egg production, feed intake, kg feed/dozen eggs and feed cost/dozen eggs as well as egg quality during the cool-wet season. Increasing the level of BFPM beyond 3.5% was found to be uneconomical and counter- productive for layers during the wet season. The bulkiness and powdery nature of the BFPM diets could probably have been responsible for the decline in the performances of layers birds fed 7.0 and 10.5% BFPM supplementations. Hen-day egg production was improved by 7.1% in cool-wet season.
