Abstract: Essential oils from the leaves of Beackea frutescens were extracted by using three hydrodistillation methods, the Dean-Stark (DS), Clavenger (C) and simultaneous steam distillation extraction (SSDE). The yield of essential oils for each method was 0.32 %, 0.40% and 0.83%, respectively. The essential oils were examined using gas chromatogram and gas chromatography-mass spectrometry. Twenty constituent of the essential oils were identified. The major compounds were terpinolene (22.33%), t- -bisabolene (10.12%), -cymene (9.85%), linalool (7.32%) and t-caryophyllene (6.06%), -bergamotene (2.42%), nerolidol (1.35%). The pure essential oils obtained and four emulsion samples which contained 0.2-0.5% of the essential oils shown antibacterial activity against Staphylococcus aureus. The inhibition zones were 10.5 -17.0 mm. The inhibition zone exhibited by the emulsion samples varied dependent on the percentage of the essential oil used.

Abstract: The present investigation was carried out on two species of freshwater fishes Oreochromis niloticus niloticus and Clarias gariepinus collected from EL-Ibrahimia and EL-Malah canals at Assuit province. Water samples were also collected for determination of some water quality parameters and the concentration of certain heavy metals including Cu, Cd and Pb. The results of water quality analysis indicated significant differences between the two selected sites. The examination of the intestinal parasites in both investigated fish species indicated that O. niloticus niloticus harbors one species of acanthocephalans, Acanthosentis tilapiae at the two investigated sites while, Clarias gariepinus was found harboring one species of nematodes, Paracamallanus cyathopharynx at site(1) and one species of trematodes, Orientocreadium lazeri at the two sites. The results also indicated that the mean concentration of the three heavy metals in water at site (1) are ranked as Cu > Cd > Pb, while at site (2) they are ranked as Cu > Pb > Cd with a highly significant difference (P<0.01) between the two investigated sites. The data also showed a differences between the fishes and their parasites from heavy metal ranking point of view, where it is ranked as Cu > Pb > Cd in both infected and uninfected fishes. In case of parasites heavy metals concentration at site (1) the investigated heavy metals are ranked as Pb > Cu > Cd in both Acanthosentis tilapiae and Orientocreadium lazeri, while they are ranked as Pb > Cd > Cu at site (2) in Acanthosentis tilapiae and Pb > Cu > Cd in Orientocreadium lazeri. Also, a significantly higher concentration of heavy metals was recorded in the parasites compared to their host fishes.

Abstract: Total petroleum hydrocarbon (TPH) contaminations in soils may be toxic to human, plants and cause groundwater contamination. To achieve maximum TpH- reduction and to establish successfull stable vegetation cover in phytoremediation method, various criteria must be considered to choose the plants carefully. In this study, germination and subsequent growth of seven plants were tested in three soils with different petroleum contamination levels. Contamination treatments consisted of C0 (uncontaminated soil), C1 (1:1 w/w, uncontaminated: contaminated soil) and C2 (1:3 w/w, uncontaminated: contaminated soil). The experimental design was completely randomized split plots with three replications per treatment. The results showed that the presence of TPH in the soil had no effect on seed germination of agropyron, white clover, sunflower and safflower although canola seedlings were sensitive to these compounds and failed to produce dry matter yield (DMY) at the end of trial period. In contrast, seed germination of canola, puccenillia and tall fescue decreased in the petroleum contaminated soils. No reduction was found in DMY of puccenillia in contaminated soils (C1 and C2 treatments) compared to control; however, the presence of TPH proportional to the contamination levels, decreased dry weight of sunflower and safflower. This reduction in growth and dry weight for tall fescue and agropyron was also observed in C2 compared to C1 treatment. Therefore, it seems that though agropyron, white clover, sunflower and safflower germinated well and the presence of TPHs in the soil treatments had no effect on their seed germination, they grew poorly. In contrast, grasses had poor seed germination but their subsequent growth and establishment in the contaminated soils was acceptable for subsequent phytoremediation trials.

Abstract: A study was conducted to ascertain the incidence and seasonal pattern of haemonchosis in sheep raised in different divisions of the Punjab province. For this purpose, faecal samples from 10,000 sheep were collected from eight divisions of Punjab and examined for the presence of Haemonchus contortus ova. The overall infection of Haemonchus contort us in these sheep was found to be 54.77%. The highest incidence of the haemonclfosis (70.72%) was recorded in Rawalpindi, followed by 68.00% in Sargodha and around 66% in Gujranwala, D.G. Khan and Bahawalpur divisions. The lowest incidence of the disease (32.00%) was recorded in Faisalabad followed by 34.00% in Multan and 34.32% in Lahore diyisions. The month-wise prevalence of haemonchosis showed the highest incidence (89.55%) in the month of July, followed by 87.13% in August. The lowest prevalence of haemonchosis (20.02%) was observed in February, followed by 29.00% in March.

Abstract: Morbid materials from 25 commercial broiler breeder farms located in Abbottabad and Mansehra districts were collected over one year period to investigate prevalence of Fowl cholera and study efficiency of various organs to be used as diagnostic tools for fowl cholera. Overall incidence of Fowl cholera was (0.80?0.26%) with a coefficient of variation of 231.45%, indicating significantly higher incidence (1.07?0.62%) in Mansehra than in Abbottabad (0.53?0.34%). Significantly (p<0.05) lower incidence of Fowl cholera was found in vaccinated (0.15?0.26%) than in non-vaccinated flocks (1.45?0.63%). Higher incidence (1.35?0.38%) of Fowl cholera was found in farms previously exposed to Fowl cholera disease as compared to those in which there was no previous incidence (0.25?0.29%). Fowl cholera was found positively (p<0.01) and significantly associated with flock age (b=0.074661?0.03389) but negatively associated with egg production (b=-16.24429?0.928103). Liver was found to be the best organ for diagnosis of Fowl cholera in broiler breeder flocks.

Abstract: The present study was carried out in Chakwal, Pakistan by collecting data from randomly selected 109 flocks to investigate cost of production, gross return and net profit per layer. Majority of the buildings in the study area were rented therefore, rent per layer was added to the total cost of production instead of depreciation on building and equipments. Overall total cost of production, gross return and net profit per layer was Rs. 393.88 ± 5.36, 432.14 ± 8.01 and 38.26 ± 6.66, respectively. Rate of return over the invested capital was 27%. Mean feed cost per layer was Rs. 302.23 ± 5.01, including Rs. 10.27 ± 0.24, 29.19 ± 0.42 and 262.77 ± 5.08 for starter, grower and layer ration, respectively. Feed cost was the major component contributing 76.73% to the total cost of production. Average cost of labor, day-old chick, building rent, vaccination, therapy, miscellaneous item, electricity, bedding material and transportation was Rs. 19.90 ± 0.45, 19.75 ± 0.05, 16.25 ± 0.26, 12.80 ± 0.10, 10.90 ± 2.32, 4.35 ± 0.09, 3.15 ± 0.07, 2.65 ± 0.09 and 1.90 ± 0.08, respectively, contributing 5.05, 5.01, 4.13, 3.25, 2.77, 1.10, 0.80, 0.67 and 0.48 % to the total cost of production. Gross return from the sale of marketable eggs, culled eggs, spent/culled bird, empty bags and manure was Rs. 388.84 ± 7.91, 3.85 ± 0.01, 35.80 ± 0.23, 2.20 ± 0.04 and 1.45 ± 0.01, respectively, contributing 89.98, 0.89, 8.28, 0.51 and 0.34% to the total return. Determining the effect of different parameters on the cost of production and net profit, large flocks, Hisex strain, brood-grow and lay system of rearing, good hygienic conditions of the farm, normal stocking rate and cage system of housing wee found to give maximum gross return as well as net profit.
