Abstract

The purpose of this study was to review the existing literature on some important morphological traits associated with reproductive and productive performance in Bangladeshi indigenous and exotic cross sheep. Sheep as small ruminants are essential parts of the crop-livestock of the mixed agricultural farming system playing a crucial role in the livelihood of smallholders in Bangladesh. They are considered risk averters for farmers in a family crisis and seasonal needs through quick sale by direct cash income. Furthermore, their physical products have socio-economic, cultural, and nutritional values: meat, milk, skin, manure, etc. In the past, a number of researchers investigated the relationship between morphometric features and reproductive and productive performance of the referred sheep. Any compilation report is yet not available. Therefore, an update database on Bangladeshi indigenous and exotic cross-breed sheep is required to identify for management and production strategy program. This paper reviewed, discussed, summarized, and compared all articles on morphometric traits and the reproductive and productive performances of sheep in Bangladesh.

Highlights

In Bangladesh, livestock is densely populated, and mainly the smallholders rear them
The smaller flock's size of Jamuna basin sheep farm might be due to less growth performance which does not fulfill the farmer's demand
Growth rate, and breed type are the main interest of smallholder sheep producers

Summary

INTRODUCTION

In Bangladesh, livestock is densely populated, and mainly the smallholders rear them. By commercialization of agriculture farming system pointed in 7th FYP, a new Indian exotic long-tailed meat-type cross breed Muzaffarnagari sheep is popularly and extensively reared by the Western part of Bangladesh viz. Meherpur, Choadanga, Rajshahi, and Chapainawabgonj districts. These Muzaffarnagari sheep originate in the western Uttar Pradesh districts of Muzaffarnagar, Bulandshahar, Meerut, and Bijnor, India. The coastal indigenous sheep (Figure 2.1) are mainly concentrated in the Patuakhali, Vola, Noakhali, Chittagong, and Lakhimpur districts of Bangladesh They are primarily reared at wet and salted grazing field areas (Islam et al, 2018).
