Improvement of Sheep Production in South-western Coastal Regions of Bangladesh through Proper Breeding and Feeding Techniques
Sheep production is popular in Bangladesh due to their high prolificacy, early maturity, better disease resistance and wide range of adaptability under adverse agro-climatic conditions. The productivity of indigenous coastal sheep is lower in terms of growth rate and mature weight due to poor genetic quality and nutrient deficiency. Therefore, the proposed research is designed to improve the productivity of indigenous sheep of south-western coastal region by appropriate breeding and feeding intervention. Twenty indigenous female sheep of 4 to 6 months age and four Garole ram of 12 months age will be collected from local market and Meherpur district, respectively to implement the project. The Garole male sheep which have higher growth rate and mature body weight will be used to breed the poor quality indigenous sheep. Four feeding trials (each of 180 day long) will be conducted to develop feeding systems for both indigenous and indigenous x Garole (F1) sheep. The sheep will be kept in individual pen and individual feeder and water bucket will be provided. Twenty female sheep will be divided into 5 treatment groups. The experimental animals will be weighed individually, blocked into five groups according to their initial live weight and assigned at random to five different grazing hours (6, 8, 10, 12 and 14 hours) taking four sheep in each group. Design of the experiment will be based on Randomized Complete Block Design (RCBD). To get maximum performance from grazing sheep, five different levels of concentrate (0g, 100g, 150g, 200g and 250g per sheep) will be supplemented to the sheep keeping the grazing hour constant to all groups. Developed feeding system will be disseminated among the sheep farmers of south-western coastal region arranging a workshop. In a nutshell, research findings would help the livestock policy maker to enhance the productivity of native sheep adopting the developed technology.
Objective of the study:
Broad Objectives: Improvement of productivity of indigenous sheep in south-western coastal region of Bangladesh through breeding and feeding management.
i. To study the prospects and problems of existing sheep production in south-western coastal regions of Bangladesh.
ii. Evaluation of feed resources available in south-western coastal region of Bangladesh.
iii. Up-gradation of indigenous sheep by crossbreeding with improved genotype.
iv. Development of feeding strategy for indigenous and crossbred sheep.
v. Skill development of sheep farmers proving training.
