Abstract
Garole sheep is very popular for its biannual lambing and disease resistance characters. To evaluate some selected serum electrolytes (Na, K and P) ions in apparently healthy Garole sheep at Sundarban region under Shyamnagar Upazila of Satkhira district, blood samples were collected from 20 Garole sheep (8 males and 12 females) of aged about 6-48 months containing male lambs, rams, female lambs, pregnant ewes and lactating ewes according to the age, sex and physiologic status. Serum was separated and used for biochemical analysis for the measurement of target serum electrolytes. The results of the range and mean ± standard error (SE) of serum electrolytes are as follows: sodium 280-400 ppm and 342.96±7.19 ppm, potassium 30-55 ppm and 34.37 ± 0.72 ppm and phosphorus 40-90 ppm and 70.98 ±1.76 ppm respectively. The significant differences (P<0.05) between males and females in serum ions levels was recorded. It can be concluded that Na, K and P ion level in serum was higher in male than female and significant differences in ion level varies according to physiologic status of female Garole sheep.

Highlights
The Garole is a prolific breed of sheep
Potassium and phosphorus in test sera of Garole sheep are presented in Table 1 and the values of these electrolytes according to sex, age and physiologic status are presented in Table 2 and 3
Along with this weaning time is an important factor in the variations of serum electrolytes and this could be compared with the study of Lepherd et al (2009) who described many properties related to weaned Merino lambs (9-16 weeks), they analyzed serum Na, K and P ions as well as complete blood picture, enzymes and other nutrients where they found the effect of weaning on their dams and there was an important correlation between age of the dam and times of newborns
Summary
The Garole is a prolific breed of sheep. High prolificacy in sheep carrying the Booroola gene (FecB) is the result of a mutation in bone morphogenetic protein receptor-IB (BMPR-IB) which had previously been identified in Garole sheep from the Sundarban region of West Bengal (Davis et al, 2002). Garole is a native and local sheep having distinct and separate phenotypic characters, productive performances of their own is not thoroughly characterized and established as Breed This distinct but inadequately studied line of small sheep (locally named as Garole) is the dominant domestic species isolated so far pointed out at this extended coastal swampy Sundarban delta of West Bengal (Banerjee, 2008). The sheep Garole is very popular for its bi-annual lambing, multiple birth, grazing on aquatic weeds and grass in knee-deep water and disease resistance characters (Banerjee, 2008) They are small in size, produce rough wool, good quality skin, manure and low fat mutton. This small compact meat type animal predominantly white in color, are owned by landless and small farmers which provide principal source of income during agriculturally lean period and govern socio-economic status of the sheep farmers of this region. During the follicular phase of oestrous cycle, oestradiol concentration increases and declines to the luteal phase (Gaafar et al, 2005)
