The present study was undertaken to find out the prevalence of gastrointestinal nematodes in pigeon (columba livia) at Rajshahi division from 01-01-2016 to 15-12-2016 and to evaluate the comparative efficacy piparazine citrate and levamisole HCL. Total 3 different species of parasites were recorded in this study and those were Ascaridia columbae, Capillilaria obsignata, Raillietina tetragona. Out of 263 pigeon, 109 pigeon having ascarid and capillaria positive were treatment with piparazine citrate and levamisole HCL. The pigeon were treated with recommended (10g mixed in 6 litre drinking water for 100 pigeon) dose of Ascarex® and recommended (1gm mixed in 1 litre drinking water) dose of Avinex® orally, respectively. The recovery rate of ascariasis at 7th days was 50.9% and capillariasis was 51.85%. After 21th days the recovery rate of ascariasis was 72.72% and capillariasis was 66.66%. The efficacy of drugs is more in case of young (77.27% at 7th days and 87.36% at 21th days) than adult (44.82% at 7th days and 65.51% at 21th days).In exotic breeds efficacy is good (60.41% at 7th days and 85.41% at 21th days) than indigenous breeds (44.26% at 7th days and 66.65% at 21th days). The recovery rate is more in traditional (65.3% at 7th days and 78.33% at 21th days) than commercial farming system (42.85% at 7th days and 58.33% at 21th days). Res. Agric., Livest.

In Bangladesh, poultry disease diagnosis almost entirely depends upon the post mortem examination. The present study was conducted to determine the prevalence of bacterial diseases and liver lesions in chickens based on gross and microscopic lesions. The study was conducted to 377 liver samples collected from chickens from July to December 2017 in the Rajshahi district, Bangladesh. During the collection of samples, clinical signs and gross changes were recorded very carefully. Histomorphological changes were investigated under a light microscope and the lesions were characterized. In this study, the overall prevalence of bacterial diseases was recorded as 14.05% whereas layer chickens (9.54%) and broiler chickens (4.50%). During the study, the prevalence of Salmonellosis was found 8.22% whereas 11.66% in layer chickens and 3.25% in broiler chickens. On the other hand, the prevalence of Colibacillosis was identified 5.83% in chickens in which 3.18% were broiler chickens and 2.65% were layer chickens. In the case of Salmonellosis, grossly livers were friable, congested, enlarged, bronze discoloration with white focal necrosis, egg follicles were congested and hemorrhagic with stalk formation; microscopically livers formed multifocal nodules with coagulation necrosis. Birds with Colibacillosis grossly showed fluid accumulation in the peritoneal cavity of chicks, dark-colored swollen liver and spleen, and perihepatitis. The fatty liver hemorrhagic syndrome showed clotted blood on the liver, congested, enlarged and friable liver, paleness of the body and excess abdominal fat. From the present study, it was evident that considerable numbers of liver lesions were observed in chicken and a systematic study of liver lesions is helpful in making a diagnosis of various poultry diseases.
Parasitism is an important limiting factor that responsible for deteriorating the health and productivity of livestock. Goat rearing is hindered by various problems, among them parasitism is an important limiting factor in Bangladesh as the climatic condition of the country favors the development and survival of various parasites. Of the parasitic problems, ectoparasitic infestations are commonly seen in goats. Common ectoparasites of animals are ticks, lice and mites which cause considerable amount of blood loss, irritation and annoyance. Mange infested goats bite and rub the affected area so that the affected skin becomes abraded. Ectoparasitic infestations reduce the quality and market value of valuable skin. Besides, ectoparasites transmit various types of deadly pathogens of animals. The objectives of this study to find out the alternative measures of mange control especially with herbal products. In the experimental study of mange control, fifteen affected goats of both sexes, aged between 10 and 30 months which were divided into four groups randomly and 3 goats were considered in each group. The treatments were considered with control (A), Neem ointment (B), Ata ointment (C), Mehedi ointment (D).The control experiment was conducted during November’2012 to December’2012 in Rajshahi district of Bangladesh. A descriptive statistical analysis and ANOVA were used for the results of clinical parameters (hair coat, skin lesion bodyweight and adverse effects). The recovery of skin lesion was statistically significant (P<0.10) in all treatment groups except control group (P>0.10).The bodyweight was increased in all treatment groups and it was decreased in control group which was significant (P>0.10).In the herbal ointments, Neem(Azadirachtaindica) was more effective for control of mange in goats than Mehidi (Lawsoniainermis) and Ata (Annonareticulata). Further studies are required to clarify the efficacy of the ethno veterinary widely used in agro ecologies, animal species and livestock management system in Bangladesh. Res. Agric., Livest.
