Abstract: The study was conducted to Survey, documentation and bionomics of Mealy bug, Pseudococcus virgatus on Kenaf (Hibiscus cannabinus L.) and mesta (H. sabdariffa L.) in different jute growing regions and in the laboratory of Entomology Department, BJRI during the jute growing 2017 and 2018 season with 10 replications following CRD design. The highest infestation of Mealybug (80.49%) was found in HC-95 of kenaf variety at Narayanganj sub-station and the lowest infestation of Mealybug (11.34%) was found in HS-24 of Mesta variety at Patuakhali sub-station of BJRI. Most infested part of plant was twig. The egg is oval in shape and measures on an average 0.315mm in length and 0.135mm in breadth. The average length of newly hatches nymphs were 0.495±0.022 mm and average wide in 0.213±0.008 mm. The first moulting occurred within 4-5 days with an average of 4.6±0.163days. The second moulting occurred within 6-9 days after first moulting with an average of 7.50±0.268 days. The third moulting occurred within 7-9 days after second moulting with an average of 8.00±0.388 days. The average length of adult male is in 1.60±0.459 mm and average breath is in 0.68±0.078 mm. The average length of adult female is in 4±0.86 mm and average breath is in 2.40±0.516 mm. The incubation period varied from 3-5days with an average of 4.7±0.94 days. The total nymphal period of pseudococcus virgatus was with an average of 20.1±1.05 days. The duration of adult male and female was an average 15.8±0.388 and 35.9±0.348 days respectively.

Abstract: Objective: In order to find out the current situation of livestock and poultry breeding waste resource utilization in agricultural areas, improve the methods and measures of livestock and poultry breeding sewage resource utilization. research method: According to the analysis of the current situation, the characteristics of livestock and poultry breeding waste resources were clarified. According to the overall requirements of ecological civilization, the specific measures of livestock and poultry breeding sewage resource utilization were put forward. Conclusion and measures: 1. To establish rules and regulations to standardize the utilization of aquaculture sewage resources; 2. To improve the facilities and consolidate the foundation of resource utilization; 3. To develop and utilize the aquaculture sewage according to local conditions; 4. To explore new business forms and establish a new mechanism for the resource utilization of aquaculture sewage; 5. To strengthen guidance and increase government policy investment.

Abstract: A total of 280 females with 28 males for Silver Sabahia strain at two different ages (35 and 50 weeks) were used in this study. Besides, 40 cocks (10 cocks / group) used for semen evaluation. Birds of each age were divided into two groups, the 1st group drank water exposed to magnetic field (MFW) and the 2nd group drank non-magnetic tap water (TW) to determine the beneficial effect of drinking magnetized water for aged chickens to cope low fertility% and hatchability%, besides studying semen and egg parameters, embryonic development and chick quality. Supplementation elder cocks with MFW significantly increased semen volume, number of motile sperm and number of live sperm compared with those for untreated cocks. Treated old flock with magnetic water had a heavier egg weight (p≤0.05) than treated young flock with magnetic water. MFW X old and MFW X young had a comparable influence on egg weight loss, embryonic mortality, fertility% and hatchability%. On day 14 and 18 of incubation, supplementation older birds with MFW water had a heavier residual yolk sac weight% compared with the other rest groups. At hatch, the residual yolk sac weight% was similar between MFW X old and MFW X young. In addition, chick weight and all internal organs weight% were not affected by interaction of both types of water and hens age. It is concluded that exposing water to magnetic field, have a stimulating influence on the percentages of fertility and hatchability of birds (especially older age) through improving semen and egg qualities, besides stimulating the development of embryogenesis.

Abstract: Across-sectional study was designed and conducted in Damot Gale district of Wolaita zone, south Ethiopia. The major objectives of the research were: to determine the prevalence of major ixodid ticks; to identify the collected ticks into their respective species; and to assess the risk factor influencing the prevalence of tick infestation in the study area. For this purpose, 384 heads of cattle maintained under traditional management system were selected using simple random sampling statistical technique. All visible ticks were collected from half body part of selected cattle, preserved in70% alcohol and transported to WSU-SVM for subsequent identification into species, based on key standards. Questionnaire survey was conducted to collect baseline information regarding farmers’ perceptions of the effects of ticks on livestock production. The collected data were analyzed using SPSS software (Version20.1) for descriptive and inference purposed. A total of 264 ixodid ticks were collected, which belonged to of Boophilus (59.85%), Rhippicephalus (25.38%) and Amblyomma (14.77%) genera, with the overall prevalence of tick infestation to be about 6%. At species level, Boophilus decoloratus (59.85), Rhippicephalusevertsievertsi (25.38%), Amblyomma variegatum (10.61%) and Amblyommagemma (4.16%) were the hard tick species identified during the survey period. Regarding spatial distribution, these ticks had the highest prevalence at Gacheno and Chocha and the lowest prevalence at Fate district. Regression analysis indicated that the prevalence of tick infestation did not reveal significant statistical difference between male and female sex groups (p>0.05). Nevertheless, adult cattle over the age of three years were more significantly challenged by tick infestation than young cattle (P<0.05). Similarly, the prevalence of tick infestation was significantly higher (p<0.01) in cattle with poor body condition than those with medium and good body condition score. In conclusion, the present research disclosed that tick infestation due to hard tick s is responsible for considerable pathogenic impacts and economic losses due to their deleterious effects on leather industry. Based on the present findings, it is recommended that integrate tick control efforts should be implemented, and the efficacy acaricides should be detected to control the risk of drug resistance in Damot Gale district.

Abstract: The present research was conducted to assess the reproductive performance, health management, and marketing system of native sheep in selected areas of Bangladesh. The data was collected from selected 11 Upazilas of 6 districts in Bangladesh. A pre-tested interview schedule was used to collect data from 1768 sheep rearing farmers by using a simple random sampling technique and analyzed descriptively. The study denoted that the age at 1st heat or puberty was 7.01±0.03 months. However, the age at 1st lambing was found 12.65±0.03 months irrespective of areas. The litter size was found 1.93±0.01 and the highest was in Balagonj (2.17±0.04) Upazila. Moreover, the average birth weight was 0.94±0.01 kg and the highest was in Companygonj (1.76±0.04 kg) followed by Subornochar (1.63±0.18 kg) Upazila. The service per conception rate was 1.10±0.01. Most of the farmers (60.18%) were used own ram 100% of farmers were used natural breeding for breeding practice. The sheep rearing farmers in the study areas were found moderately aware of different neo-natal nourishment practices. However, only 6.39% of farmers in different study areas found dipping of their sheep. The sheep mostly affected by pneumonia (43.72%), diarrhea (40.33%), alopecia (28.51%), bloat (22.79%), and parasitic infection (15.55%) found in the study areas. The dog bite (15.55%) was found a major problem in native sheep rearing irrespective of the study areas. Only 28.51% and 12.56% of farmers were used anthelmintic and vaccine respectively. Most of the farmers sell their sheep in the hat/Bazar (82.75%) and 60.46% of farmers sell sheep to paiker or bapari followed by the butcher (22.33%). Furthermore, most of the farmers (82.28%) fixed value for the sheep on the basis of eye estimation. There was no record of wool selling irrespective of study areas. Lack of organized and structured marketing system found in the study areas. Emphasis should be given to the sustainable improvement of native sheep and marketing systems to improve the livelihoods of rural poor farmers in Bangladesh.
