Characteristics of body weight, wither height, rump height, body length, sternum height, Chest girth, bi-coastal diameter, ear length, rump width, head width, rump length, head length, heart girth, cannon bone circumference and muzzle diameter were collected from 508 (458 female and 50 male) sheep stratified into age categories of <1year, 1-1.5 year, 1.5-2 years, 2-2.5 years and >2.5 years by dentition. The average body weight of sheep was 18.03±1.91 kg irrespective of sexes and was significantly (p<.01) higher in male. The body weight of sheep was increased gradually with the advancement of age. The wither height (cm), rump height (cm), body length (cm), sternum height (cm), Chest girth (cm), bi-coastal diameter (cm), ear length (cm), rump width (cm), head width (cm), rump length (cm), head length (cm), heart girth (cm), cannon bone circumference (cm) and muzzle diameter (cm) were 52.75±2.56, 52.70±2.90, 55.61±3.04, 26.89±2.28, 61.65±3.38, 11.27±.88, 7.28±3.17, 13.57±1.03, 11.44±.85, 11.40±1.32, 19.02±1.47, 70.15±6.79, 8.56±.77, 20.04±1.52 respectively. The wither height, sternum height, body depth, bi-coastal diameter, head width, head length, cannon bone circumference and muzzle diameter were significantly differed (p<0.001) between male and female and value of all mentioned characters were higher in male. The results indicated that the rump height, body length, bicoastal diameter, head width, rump length, head length and muzzle diameter were non-significantly differed among different age categories but all of these were higher at aged sheep. Heart girth was differed significantly (p<.01) among ages and highest in full permanent teethed sheep. Cannon bone circumference differed significantly (p<0.05) among different ages and also highest at aged sheep. Though Heart girth did not differ significantly between sexes, it was higher in female probably for their pregnancy. Introduction Bangladesh is a sub-tropical country, favorable for sheep rearing, as they can be maintained under rural conditions because of their ability to adapt to harsh environment, poor management and feeding practices. There are about 3.537 million sheep in Bangladesh (DLS, 2019). Most of the sheep are indigenous, with few crossbreds [1] and are capable of bi-annual lambing and multiple births. Native sheep are extremely resistant to infectious diseases including PPR [2]. Under traditional feeding systems, the sheep are raised on harvested or fallow lands, roads, and canal sides [3] and also graze on aquatic weeds and grass in knee-deep water. No other domestic animals are capable of existing on such feed. Sheep are tolerant to disease in the humid and sub-humid tropics. With their small muzzles and split upper lips they can nibble tiny blades of vegetation, which cannot be eaten by bigger animals [4]. Sheep rearing is directly involved with poverty alleviation, employment generation and good quality nutrients supply. In these situations, where there are absent to access industrial and rigid beneficial agricultural facilities, formal financial and insurance institutions, small ruminants are “easy to cash” assets [5]. As human population is increasing day by day in the Barind region of the country, the access of rural families to land, capital, and labor diminishes while opportunities for income from off-farm activities become scant. As a result, households are often forced to enter small ruminants rearing and face consumption and income shocks Citation: MI Haque, Sarder MJU, Islam MA, Khaton R, Islam MH, et al. (2020) Morphometric Characterization of Barind Sheep of Bangladesh. J Earth Environ Sci 4: 192. DOI: 10.29011/2577-0640.100192 2 Volume 4: Issue 01 J Earth Environ Sci, an open access journal ISSN: 2577-0640 Small ruminants are also important in a diversification strategy that aims to reduce market and climatic risks and optimize the use of available resources [6]. In Barind region of Bangladesh, the roles of sheep in the livelihoods of rural households and their characterization have not been comprehensively investigated. So, there is limited information regarding morphometric feature and the potential of Barind sheep. This study was designed to assess the morphological characters to available the information about Barind sheep for taking intensive plan for improving and conservation of positive characters of Barind sheep. Materials and Methods The study was carried out in Barind region of Rajshahi district in Bangladesh. Among the rural activities, rain fed agriculture (51.33%) is the most important, followed by livestock keeping (13%) and off-farm activities (3%). Cattle, goat, sheep and poultry, were the main livestock species kept. The Barind tract lies in the monsoon region of the summer dominant hemisphere. The climate of the area is generally warm and humid. This region has already been designated as draught prone. The average temperature ranges from 250C to 450C in the hottest season and 50C to 15°C in the coolest season with an average relative humidity of 75%. The research area was located between 240.18ʹ and 240.36ʹ North latitude and between 880.17ʹ and 880.43ʹ East longitude. Data were taken from 508 (458 female and 50 male) adult sheep of 60 household of two Barind based upazila; Paba and Godagari under Rajshahi district. Flock size varied from five to fifteen in no. All farmers used extensive production systems and sheep were reared only on grazing without any supplementation. Body measurements were taken on animals in a standing position with a raised head. Data were collected from March 2019 to August 2019. Measurements of 15 characters (Body weight, withers height, rump height, body length, sternum height, Chest girth, bicostal diameter, ear length, rump width, head width, rump length, head length, heart girth, cannon bone circumference, muzzle diameter) were taken by using a metric tape and digital hanging weighing balance accordance with the guidelines described by the FAO (2012). The collected data on morphology were checked, compiled and analyzed. The data on studied traits were analyzed using the statistical software SPSS, version 23. Results and Discussion Animal morph structure is defined by body dimensions and the relationships between them. These relationships determine the productive functionality and suitability of the animal in the meat, milk or dual-purpose performance. Results were expressed as mean, standard deviation and coefficient of variation for each linear measurement. The morphometric features of Barind sheep on average, comparison between sex, among age according to dentition and comparison between two upazilas are shown in (Tables 1-4) respectively.

进行这项研究的目的是描述孟加拉国Barind羊的形态特征，试图为深入研究提供一个重要工具，以制定适合该地区生产系统的管理和育种战略。收集资料，研究了两个巴林德县的羊的形态特征;通过密切观察、测量和记录保存，孟加拉国拉杰沙希地区的帕巴和戈达加里。收集508只羊(母羊458只，公羊50只)体重、残高、臀高、体长、胸骨高、胸围、双肩直径、耳长、臀宽、头宽、臀长、头长、心围、胸骨围和口鼻直径的特征，按牙列划分年龄为2.5岁。雌雄绵羊平均体重为18.03±1.91 kg，公羊显著高于(p< 0.01)公羊。随着年龄的增长，绵羊的体重逐渐增加。臀高(cm)、臀高(cm)、体长(cm)、胸骨高(cm)、胸围(cm)、双肩直径(cm)、耳长(cm)、臀宽(cm)、头宽(cm)、臀长(cm)、头长(cm)、心围(cm)、炮骨围(cm)、炮口直径(cm)分别为52.75±2.56、52.70±2.90、55.61±3.04、26.89±2.28、61.65±3.38、11.27±。88、7.28±3.17、13.57±1.03、11.44±。85、11.40±1.32、19.02±1.47、70.15±6.79、8.56±。77, 20.04±1.52。雄性和雌性的枯高、胸骨高、体深、双岸直径、头宽、头长、炮骨围和炮口直径差异极显著(p<0.001)，且雄性高于雌性。结果表明:不同年龄羊的臀高、体长、双肩直径、头宽、臀长、头长和口鼻直径差异不显著，但在老年羊均较高。心围在不同年龄间差异显著(p< 0.01)，以全恒齿羊最大。不同年龄羊的炮骨周长差异显著(p<0.05)，以老龄羊最高。虽然心脏围度在两性之间没有显著差异，但女性的心脏围度可能因为怀孕而更高。孟加拉国是一个亚热带国家，有利于羊的饲养，因为它们能够适应恶劣的环境，管理不善和饲养方法，因此可以在农村条件下饲养。孟加拉国约有353.7万只羊(DLS, 2019年)。大多数羊都是本地的，很少有杂交品种，并且能够一年产两胎和多胎。本地羊对小反刍兽疫[2]等传染病具有极强的抵抗力。在传统的饲养系统中，羊被饲养在收获或休耕的土地上、道路上和运河边，也吃水草和及膝深的水。没有其他家畜能够靠这种饲料生存。在潮湿和半潮湿的热带地区，羊能忍受疾病。它们的小口部和裂开的上嘴唇可以咬下更大的动物不能吃的植物叶片。养羊直接关系到扶贫、创造就业和优质营养供应。在这些情况下，没有工业和刚性的有益农业设施，正规的金融和保险机构，小反刍动物是“容易变现”的资产。由于该国巴林德地区的人口日益增加，农村家庭获得土地、资本和劳动力的机会减少，而从非农活动中获得收入的机会也越来越少。因此，家庭往往被迫从事小型反刍动物饲养，并面临消费和收入冲击引文:MI Haque, Sarder MJU, Islam MA, Khaton R, Islam MH等。(2020)孟加拉国Barind羊的形态计量学特征。[J] .环境科学学报(自然科学版)，41(2):391 -

Morphometric Characterization of Barind Sheep of Bangladesh

The study was undertaken aiming to characterize the morphological features of Barind sheep of Bangladesh in an attempt to give an important tool for intensive research to develop a management and breeding strategy that suits the production system of the area. Data were collected to study the morphological features of sheep of two Barind based upazillas; Paba and Godagari under Rajshahi district of Bangladesh through close observation, measuring and record keeping. Characteristics of body weight, wither height, rump height, body length, sternum height, Chest girth, bi-coastal diameter, ear length, rump width, head width, rump length, head length, heart girth, cannon bone circumference and muzzle diameter were collected from 508 (458 female and 50 male) sheep stratified into age categories of <1year, 1-1.5 year, 1.5-2 years, 2-2.5 years and >2.5 years by dentition. The average body weight of sheep was 18.03±1.91 kg irrespective of sexes and was significantly (p<.01) higher in male. The body weight of sheep was increased gradually with the advancement of age. The wither height (cm), rump height (cm), body length (cm), sternum height (cm), Chest girth (cm), bi-coastal diameter (cm), ear length (cm), rump width (cm), head width (cm), rump length (cm), head length (cm), heart girth (cm), cannon bone circumference (cm) and muzzle diameter (cm) were 52.75±2.56, 52.70±2.90, 55.61±3.04, 26.89±2.28, 61.65±3.38, 11.27±.88, 7.28±3.17, 13.57±1.03, 11.44±.85, 11.40±1.32, 19.02±1.47, 70.15±6.79, 8.56±.77, 20.04±1.52 respectively. The wither height, sternum height, body depth, bi-coastal diameter, head width, head length, cannon bone circumference and muzzle diameter were significantly differed (p<0.001) between male and female and value of all mentioned characters were higher in male. The results indicated that the rump height, body length, bicoastal diameter, head width, rump length, head length and muzzle diameter were non-significantly differed among different age categories but all of these were higher at aged sheep. Heart girth was differed significantly (p<.01) among ages and highest in full permanent teethed sheep. Cannon bone circumference differed significantly (p<0.05) among different ages and also highest at aged sheep. Though Heart girth did not differ significantly between sexes, it was higher in female probably for their pregnancy. Introduction Bangladesh is a sub-tropical country, favorable for sheep rearing, as they can be maintained under rural conditions because of their ability to adapt to harsh environment, poor management and feeding practices. There are about 3.537 million sheep in Bangladesh (DLS, 2019). Most of the sheep are indigenous, with few crossbreds [1] and are capable of bi-annual lambing and multiple births. Native sheep are extremely resistant to infectious diseases including PPR [2]. Under traditional feeding systems, the sheep are raised on harvested or fallow lands, roads, and canal sides [3] and also graze on aquatic weeds and grass in knee-deep water. No other domestic animals are capable of existing on such feed. Sheep are tolerant to disease in the humid and sub-humid tropics. With their small muzzles and split upper lips they can nibble tiny blades of vegetation, which cannot be eaten by bigger animals [4]. Sheep rearing is directly involved with poverty alleviation, employment generation and good quality nutrients supply. In these situations, where there are absent to access industrial and rigid beneficial agricultural facilities, formal financial and insurance institutions, small ruminants are “easy to cash” assets [5]. As human population is increasing day by day in the Barind region of the country, the access of rural families to land, capital, and labor diminishes while opportunities for income from off-farm activities become scant. As a result, households are often forced to enter small ruminants rearing and face consumption and income shocks Citation: MI Haque, Sarder MJU, Islam MA, Khaton R, Islam MH, et al. (2020) Morphometric Characterization of Barind Sheep of Bangladesh. J Earth Environ Sci 4: 192. DOI: 10.29011/2577-0640.100192 2 Volume 4: Issue 01 J Earth Environ Sci, an open access journal ISSN: 2577-0640 Small ruminants are also important in a diversification strategy that aims to reduce market and climatic risks and optimize the use of available resources [6]. In Barind region of Bangladesh, the roles of sheep in the livelihoods of rural households and their characterization have not been comprehensively investigated. So, there is limited information regarding morphometric feature and the potential of Barind sheep. This study was designed to assess the morphological characters to available the information about Barind sheep for taking intensive plan for improving and conservation of positive characters of Barind sheep. Materials and Methods The study was carried out in Barind region of Rajshahi district in Bangladesh. Among the rural activities, rain fed agriculture (51.33%) is the most important, followed by livestock keeping (13%) and off-farm activities (3%). Cattle, goat, sheep and poultry, were the main livestock species kept. The Barind tract lies in the monsoon region of the summer dominant hemisphere. The climate of the area is generally warm and humid. This region has already been designated as draught prone. The average temperature ranges from 250C to 450C in the hottest season and 50C to 15°C in the coolest season with an average relative humidity of 75%. The research area was located between 240.18ʹ and 240.36ʹ North latitude and between 880.17ʹ and 880.43ʹ East longitude. Data were taken from 508 (458 female and 50 male) adult sheep of 60 household of two Barind based upazila; Paba and Godagari under Rajshahi district. Flock size varied from five to fifteen in no. All farmers used extensive production systems and sheep were reared only on grazing without any supplementation. Body measurements were taken on animals in a standing position with a raised head. Data were collected from March 2019 to August 2019. Measurements of 15 characters (Body weight, withers height, rump height, body length, sternum height, Chest girth, bicostal diameter, ear length, rump width, head width, rump length, head length, heart girth, cannon bone circumference, muzzle diameter) were taken by using a metric tape and digital hanging weighing balance accordance with the guidelines described by the FAO (2012). The collected data on morphology were checked, compiled and analyzed. The data on studied traits were analyzed using the statistical software SPSS, version 23. Results and Discussion Animal morph structure is defined by body dimensions and the relationships between them. These relationships determine the productive functionality and suitability of the animal in the meat, milk or dual-purpose performance. Results were expressed as mean, standard deviation and coefficient of variation for each linear measurement. The morphometric features of Barind sheep on average, comparison between sex, among age according to dentition and comparison between two upazilas are shown in (Tables 1-4) respectively.
