Abstract/ Executive Summary:

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 1^st heat or puberty was 7.01±0.03 months. However, the age at 1^st 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 their 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 farmer's (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.

Objectives:

To assess the reproductive performance, health management, and marketing system of native sheep in selected areas of Bangladesh.

Methodology:

The present work was conducted following the logical research methodology. At first, the problem was identified and relevant literature was reviewed. A total of 11 native sheep populated Upazilas of 6 districts were selected purposively. A team of scientists and enumerators were collected the data from respected Upazilas. The interview schedule was developed following the scope of study and rationally. Then the interview schedule was pre-tested and the necessary correction was made. Both quantitative and qualitative data were collected. Some open questions were included for acquiring qualitative data for determining people’s estimation and feelings. The sheep rearing households were the sample of the research. At first, households were stratified by livestock rearing categories with the help of Upazila Livestock Officer (ULO) of respected Upazilas, and from 10 Upazilas 4 unions and 3 villages from each union were chosen for conducting the survey. However, from Nikhongchari Upazila, data were collected through listed sheep farmers. Therefore, a total of 1768 sheep rearing households were surveyed using a simple random sampling technique. Both male and female staff were involved at the local level for data collection, entry, analysis, and write-up. In order to minimize the level of bias and to improve objectivity, local staff from respective areas was to be assigned to collect data and adequate training was given to the enumerators. Then data was collected through direct face-to-face and on-farm interviews. The parameters considered for reproductive performances were as follows: age at 1^st heat, age at 1^st lambing, litter size, birth weight of lamb. The age at puberty was estimated as the age of the first estrus of the ewe. The sing is wagging tail, swelling, and mucus discharge from the vulva, jumping tendency to others, rubbing their body with the rams and remain closer to the rams. The age at first lambing was calculated in days from the date of birth to the date of first lambing [7]. The litter size was calculated as the number of lamb born/conception/ewe. The litter size was calculated by the following formula: Litter size (prolificacy)= a number of lambs/number of ewes lambing. The lamb birth weight is the weight of newborns within 24 hours of the birth date. Lamb birth weight was measured by weighing balance and values were recorded in kg. This is defined as the number of services or insemination required per conception [8]. After completion of data collection, the data were carefully inputted to MS Excel as per output tables. Both the qualitative and quantitative data were summarized and analyzed descriptively using MS Excel and SPSS 20.0.

Achievement/Findings:

From the study, it may be concluded that the reproductive performance of native sheep was found good irrespective of the study areas. All the native sheep farmers were used natural breeding practices. The sheep rearing farmers in the study areas were found moderately aware of different neo-natal nourishment practices. The native sheep mostly affected by pneumonia, diarrhea, alopecia, bloat, and parasitic infection found in the study areas. However, the dog bite was found a major problem in native sheep rearing irrespective of the study areas. The use of anthelmintic and vaccine was found poor irrespective of the areas. Moreover, the marketing system of native sheep was found also very poor. Lack of organized and structured marketing system found in the study areas. Emphasis should be given to the sustainable improvement of reproductive and health management of native sheep and marketing systems to improve the livelihoods of rural poor farmers in the context of Bangladesh.
