The faecal samples were collected from 112 indigenous cattle from Jhikargacha Upazilla of Jashore district with a random sampling. The study was conducted February 2020 to January 2021. Faecal sample examination of all the selected cattle showed that 29.44% (33) animals were affected with single type of GI nematode. Among them, Toxocara vitulorum is highly prevelant with a prevalence of 9.82%. Other species, namely Trichuris trichiura, Bunostomum phlebotomum, Haemonchus contortus and Strongyloides papillosus are also found significantly. Mixed infections were observed in 8.03% cattle where two or more species of nematodes are noticed. The prevalence of gastro-intestinal helminths was significantly higher in young cattle (50%) than adult (22.5%) cattle. About 33.33% male and 26.86% female cattle were infected with at least one type of gastro-intestinal nematode infestation. Both mixed and single infection was significantly higher in male cattle than those of female cattle. During summer season, prevalence is found higher (35.71%) than winter (20.51%) and rainy season (32.26%). Extensive rearing system is identified as more prevalent (34.78%) in gastro-intestnal nematodiasis than intensive (25.0%) and semi-intensive rearing system (26.31%). Cachectic animals having body condition score 1, are highly prevalent (33.33%) than others. The efficacy of Pipervet® and Almex® against Ascaris infection of were found 100% and 80% respectively whereas Levavet® and LTvet® were found 100% and 90.91% effective against single type of infection with Trichuris trichiura, Bunostomum phlebotomum, Haemonchus contortus and Strongyloides papillosus. The efficacy of Levavet® and LTvet® against mixed infection were 100% and 83.3% respectively . Using Pipervet®, Almex®, LTvet® and Levavet® body weight was gained after 1 month 8.88%, 10.41%, 6.57%, 6.17% respectively. These differences were not statistically significant.

A field survey was conducted regarding the management and utilization of tannery solid waste in response to its use in livestock feed at Hemayetpur, Dhaka, Bangladesh, the mostly tannery dense area of the country. 20 different respondents (manager) from 20 different types of tanneries were interviewed to attain the exact picture of tannery waste management and utilization. According to the study, the generation rate of solid waste is 28.88% of total raw hides and skin. On the other hand, the percentage of generation of finished leather which was referred as the final product by the author was 22.72%. Among all the different types of tannery solid wastes chrome shaving was generated at 31.8% based on total amount of solid waste. After this the rate was 28.85% in case of Chrome splitting generation. The main type of solid waste which has raised concern for the use as poultry feed is Wet blue trimmings which was generated at 3.84%. The study also unearthed that 55% of the tanneries dispose their tannery solid by landfilling and 30% sell their solid waste for poultry feed preparation. Besides, the study showed that only 0.019% of the total poultry feed produced a year in this country could be consisted of tannery solid wastes which is trivial in number and negligible. It is the food for thought for the researchers whether the safety level of heavy metals is ensured in poultry feed and for the food safety for human consumption.

AREFATUL Quality of feed is essential at all stages in the production of broiler so that birds can get wholesome nutrition. The aim of the study was to evaluate the quality of commercial broiler feeds (starter & grower) collected from tannery industrial area to ensure the food safety. Under the study, registered and unregistered (local) company’s feeds were collected from the farmers who were related to rearing broiler at Saver, Dhaka. Samples were collected to observe the physical properties, the proximate component (moisture & crude protein) and the concentration of heavy metals (Cr, Pb) of broiler feeds. To know the physical properties, feeds were visually observed. The feeds were normal in color, smell and free from any foreign matters & molds, indicated the fresh quality of feeds. The moisture was obtained in normal range and calculated as (11.31-14.03) % and (9.65-11.48) % for broiler starter and grower respectively. The crude protein contents ranged from (8.45-25.36) % and (10.23-19.34) % for broiler starter and grower feeds respectively. Almost all of the local feed samples were composed of low amount of crude protein than the registered company’s feeds. The concentration of heavy metals of most of the feed samples were below detection level that indicated the good quality of feeds. No alarming material was found in feeds and for both broiler starter and grower feeds, which indicates that the meat from broiler fed the evaluated feeds are safe for human consumption.

The experiment was carried out to study the effect of irrigation management on growth and yield of fodder grasses conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2020 to January 2021. Four grass varieties viz. V 1 (Napier grass), V (Para grass), V 3 (Pakchong grass) and V (German grass) with four levels of irrigation including control viz. I 0 4 (control; no irrigation), I (Irrigation at 20 days of plantation), I 2 (Irrigation at 20 and 40 days of plantation) and I 1 (Irrigation at 20, 40 and 60 days of plantation) were considered for the present study. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Regarding varietal performance, V 3 3 (Pakchong grass) performed best in terms of growth, yield and yield contributing parameters followed by V 1 (Napier grass) but the variety V (Para grass) gave the highest protein content compared to other varieties. In terms of irrigation effect considering growth, yield and yield contributing parameters and quality parameters I (Irrigation at 20, 40 and 60 days of plantation) showed the best performance in comparison to other irrigation treatments including control. In case of the treatment combination of variety and irrigation, the highest plant height (90.47 cm), number of leaves plant 3 -1 (45.10), number of branches plant -1 (18.73), internode length (11.97 cm), number of internodes tiller -1 (10.77), fresh weight plant (436.10 g), dry weight plant -1 (54.73 g), fresh weight plot -1 (5.23 kg) and fresh yield ha (9.69 t) were achieved from V 3 I 3 whereas control irrigation I (no irrigation) gave the lowest results on respected parameters. Regarding quality parameter, the highest protein content (12.93%) was recorded from V 2 I 3 0 whereas V 1 I gave the lowest protein content (7.45%). So, it can be concluded that the treatment combination of V 0 (Pakchong grass with 3 Irrigations at 20, 40 and 60 days of plantation) can be considered as the best compared to other treatment combinations and can be suggested at field level application. -1 2 -1 3 I 2 3 A Thesis Submitted to the Department of Animal Production and Management, Faculty of Animal Science and Veterinary Medicine, Sher-e-Bangla Agricultural University, Dhaka, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN ANIMAL SCIENCE Semester: January - June, 2021 2021-06-01T00:00:00Z
