“…The higher weaning weight of lamb depends on birth weight and daily milk yield of ewes i.e. the pre and post-natal nutrition of ewes (Ahmed et al, 2017). Although, ewes post-partum heat period did not significantly affect by different plane of nutrition but it reduced with the increased supplementation of concentrate that helps to reduce kidding interval (Ahmed et al, 2017).…”

“…Milk yield of ewe is the main factor affecting lamb growth during the first few weeks of life and are highly correlated during the 4-6 weeks of age (Owen, 1976). Several researchers like Susin et al (1995) for Polypay ewes, El-Shakhretet et al (1996) for Jordanian Awassi ewes, Shams al-dain et al (2003) for Iraqi Awassi ewes Aziz and Al-Dabbagh (2008) for Hamandi ewes and Ahmed et al, (2017) in native Bengal ewes, were also reported that milk yield was affected by plane of nutritional before and after lambing. In supporting the above findings by different authors, the present study observed a strong positive linear relationship (Fig.…”

“…Chemical composition of the natural grass in pasture and supplemented concentrate feed for ewe and lamb post-natal weight traits of lambs for different plane of nutrition in late pregnant ewes (Aziz and Al-Dabbagh, 2008). It has been generally shown that BW of lambs not only depends on the nutrition of ewes during late stage of pregnancy but also correlated with litter size and sex of lambs (Ahmed et al, 2017).…”

“…The first few weeks of lamb's growth depends basically upon milk intake (Mekoya et al, 2009, Ahmed et.al., 2017 and, thus, improving ewe nutrition may be a more effective way to enhance lamb development. Inadequate nutrition during late gestation and lactation might led to a reduction of birth weight, mammary development and milk production (Aziz and Al-Dabbagh, 2008, Jaquiery et al, 2007, Ford et al, 2007, Hamada et al, 2013, Abd-Allah, 2013, Ahmed et al, 2017. Besides, when multiple bearing ewes are offer additional feed in late pregnancy, lamb mortality is reduced for single and twin lambs (Scales et al, 1986).…”

The study was conducted to know the effect of different levels of pre and post-natal nutrition on the performances of ewes and their lambs until 1 year of age and the profitable slaughter age of lambs under semi intensive system. Twenty eight (28) native Bengal ewes at 7 weeks of gestation were randomly assigned to four groups (T0, T1, T2, T3) and supplemented with a concentrate mixture at 0.0, 1.0, 1.5, 2.0% of their body weight respectively. Ewes were allowed to graze 8 hours daily. Creep mixture (20 g/lamb/day) was provided to lambs from 2 weeks age with an increment of 10 g/lamb/week. After weaning, 20 growing male lambs were selected and reared 01 year of age with concentrate mixture at 1.5% of their body weight and 8 hours grazing irrespective of treatment groups. Parameters like, ewe’s litter size, daily milk yield, post-partum heat and lamb’s birth weight, weaning weight, live weight at 06, 09 and 12 months were recorded. The data were analyzed in an ANOVA with CRD by using SPSS v. 20. The mean differences were tested by DMRT at a probability level of P<0.05. After weaning, the lamb growths were analyzed considering age as fixed factor. Regression correlations among different parameters with different ages were also performed. Significantly higher daily milk yield (P<0.01), weaning weight (P<0.05) and daily weight gain of lamb until weaning (P<0.05) were observed in T2 group. Besides, lambs weight at 06, 09, and 12 months differ significantly (P<0.01) along with corresponding daily weight gain (P<0.05). Lambs daily weight gain did not differ significantly from weaning to 09 months of age but significantly reduced (P<0.05) from 09 to 12months age. Finally, it may be concluded that a concentrate diet containing 20% CP during late pregnancy to lactation should be supplied to obtain maximum performances of ewes and their lambs. Besides, native Bengal lamb would be slaughtered between 06 to 09 months of age to get maximum return. Bang. J. Livs. Res. Vol. 26 (1&2), 2019: P. 43-50

“…Jamuna basin, Barind tract and coastal belt sheep have the great potentiality for profitable lamb production that might fulfil the meat requirement, livelihood improvement and sustainable earning option. Lacks of public awareness, misconception about sheep meat (lamb/mutton), and inadequate nutrition supplementation are the limiting factors for sheep farming in Bangladesh (Ahmed et al, 2017). Under traditional feeding systems, sheep are raised on harvested or fallow lands, roads, and canal sides and also grazed on aquatic weeds and grass in knee-deep water without any supplementation (Sultana et al, 2010).…”

Socio-Economic Characteristics and Present Scenario of Sheep Farmers at Sherpur District In Bangladesh

This study was aimed to investigate the socio-economic characteristics and present scenario of farmers engaged in sheep production at Sherpur district in Bangladesh. Data were primarily collected with a pre-tested interview schedule from the local sheep farmers. Results showed that average family size, male and female ratio and age was 5.58, 3:10, and 45.23 year, respectively. Family size, land size and yearly livestock income was found significant (P<0.01). Most of the farmers belong to primary education (46.70%) and illiterate (30.00%). Maximum numbers of farmers belong to small holder (81.91 decimal of land). The average monthly income and expenditure of farmers was estimated BDT 10123.00 and 11476.00, respectively. The male partner was dominant over female partner in different decision-making process. The co-efficient of family size (-9843.99), land size (404.27) and yearly livestock income (1.02) was significantly different (P<0.05). It is implied that one unit increases of land size and yearly livestock income might help in increasing 404.27 and 1.02 unit in family yearly income, respectively whereas, one unit increase of family size, resulted 9843.99 unit decreases of yearly family income, considering all other variables constant. It is concluded that there is great opportunity to improve livelihood of the small farmers particularly increase family income through sheep farming in the study areas. SAARC J. Agric., 19(1): 185-199 (2021)
