The study aimed to formulate the suitable development strategies to control helminthiasis in pig by understanding the nature of the epidemiological pattern that is yet to exploit to further enhance its productivity. A longitudinal study was done to find the general prevalence pattern of helminth parasites from June/ July 2017 to May/June 2018 in the research farm of Swine and Avian Research Program, Khumaltar. A total of 50 animals of different age groups were considered for the study and they were deprived of antihelminthic treatment throughout the study period. The fecal samples were collected at 3-4 months interval and EPG was done as per the standard protocol. Three different groups of antihelminthic were used including a control group as different treatments and they were assigned as T1- Pyrantel pamoate, T2- Benzimidazoles, T-3 Imidazothiazole, and T-4 Control. The EPG was done for at least 3-week post-treatment. The result of this study showed the significant effect of the season (p<0.05) as a high prevalence of roundworms especially Ascaris (60%) and Strongylus (40%) during June/ July with more than 30 cases. However, a slight increase in parasitic prevalence was seen in September/October and Jan/Feb too. Similarly, all the antihelminthics used were 100% effective (p>0.05) against these roundworms. The female and young groups of animals showed remarkable symptoms of parasitic infections compared to the male ones. In conclusion, the different groups of drugs demonstrated very satisfactory performances in terms of the removal of parasites for good health of pigs and these should be given at 3-4 months interval as routine deworming schedule.
This study was undertaken to evaluate the egg quality parameters of New Hampshire and Giriraja by maintaining four different flocks (lines) of New Hampshire viz. NH-Khajura, NH-Parwanipur, NH-Khumaltar and NH-Pokhara and three different flocks (lines) of Giriraja viz. GR-Pakhribas, GR-Khumaltar and GR-Tarhara. The 40-60 weeks of hatchability, fertility, external and internal egg quality parameters were studied and recorded. A total of 200 birds (40 weeks of age) of each New Hampshire and Giriraja from each line were maintained on deep litter system. Results from this study indicated the significant effect of genotype and respective lines on fertility and hatchability of eggs. Significant (P<0.05) variation in fertility and no significant variation in hatchability for genotypes were found. However, in terms of fertility and hatchability, there were significant variations in different lines. In case of egg weight: no significant (P<0.01) variation was obtained for genotype but lines comparison showed significant variation. Other external egg quality parameters like egg length, egg diameter, shape index, shell thickness were examined for evaluating the genotype and line effect. In all these external egg quality parameters, there were significant (P<0.01) effect of both genotype and lines of birds. For internal egg qualities, yolk weight (g), yolk index, albumen weight and albumen index were checked. Genotype had no significant (P<0.01) effect but lines had significant (P<0.01) effect on yolk weight. In case of yolk index, both genotype and lines of bird had no significant effect. For albumen weight and albumen index, genotype of birds had no significant (P<0.01) effect but lines of bird had significant (P<0.01) effect on both parameters. The study showed that the egg quality parameters of NH (Khajura) were better than that of GR. Among different lines New Hampshire (Khajura) showed better performance in terms of egg quality parameter. Bang. J. Anim. Sci. 2020. 49 (2): 108-118
More than 50% of the households of Gandaki province have been rearing buffaloes. Whereas in mid hills 1-2 number of buffalo is present in most houses which are reared for sustainable purpose. A cross sectional study was carried out for a year in the mid hills of Gandaki province selecting 20 farms from four locations; Parbat, Nagi ramche, Tarakhola and Lwang ghalel, Kaski. Similarly, for a year a buffalo farm of Directorate of Agricultural Research, Gandaki was also studied. The purpose of this study was to determine the feeding system of buffalo in midhills and DoAR farm and compare the milk production. The milk production by the indigenous buffalo of local farms (3.3liters/d) was significantly higher than that of DoAR farms(2.9 liters/d) despite of feeding balanced concentrate ration daily. The raulo and khar combination was the main source of roughages whereas maize, barley and millet flour were the common source of concentrate for the indigenous buffalo in mid hills of Gandaki province.
