The study was conducted to phenotypically characterize the Bengal (Desi) sheep in some purposively selected villages of Nadia and Murshidabad districts of West Bengal, India. The Bengal sheep is reared as mutton sheep and has not been studied or characterized. Qualitative (coat colour and tail type) and quantitative (height at withers, height at rump, chest circumference, paunch girth, oblique body length, head length, head width, ear length, horn length, shoulder width, ear width, pelvic width, canon length, length of the fore leg, length of the hind leg, fore canon circumference, neck circumference, neck length, body weight) traits were included in the study. Phenotypic traits indicated that the sheep is of a small, thin tailed type adapted to grazing in water logged areas and lowly to moderately prolific. The structural indices indicate that the sheep is forward aligned, robust and rectangular in shape; it is well balanced and adapted for humid climates. The wool is coarse and hairy type, used for making blankets and durries. The reproductive parameters indicate that the age at first service was 295 days for ewes and 252 days for rams while the age at first lambing averaged around 425 days. Conservation efforts and genetic characterization are needed to maintain the breed purity and further studies regarding the carcass and mutton quality traits need to be carried out

Introduction. Angiotensin I-Converting Enzyme(ACE) is a key component in regulation of blood pressure by virtue ofthe rennin-angiotensin system. ACE converts the inactive decapeptide,angiotensin I, into the potent vasopressor octapeptide, angiotensinII, and inactivates bradykinin, which has a vasodilating action. So,inhibition of ACE has become a major target in control ofhypertension. It is well known that the consumption of fruits couldprovide health benefits by lowering the risk of chronic diseases suchas metabolic syndrome diseases including type 2 diabetes andcardiovascular disease. Our current study was focused on investigatingthe ACE inhibitory property of a few underutilized minor fruits ofWest Bengal using an in vitro assay. Materialsand methods. The potential antihypertensive activity ofunderutilized indigenous edible fruits of West Bengal, India, wasevaluated by their ability to inhibit Angiotensin-Converting Enzyme(ACE). The ACE inhibitory property was assayed using ACE from rabbitlung and hippuryl-histidyl-leucine as the substrate. Nineteen fruitspecies belonging to 15 families were investigated. The percentage ACEinhibitory activities of these fruits were studied at 20 µg freshweight of fruit extract per mL. The total phenol content of all thesefruits was determined following the standard Folin-Ciocalteu method.Total flavonoid content was also measured. Results. Theaqueous fruit extracts of the red variety of Trapabispinosa, Phoenix sylvestris,Cicca acida, Achras sapota andAverrhoa carambola presented more than 75% ACEinhibition. On the other hand, Punica granatum,Spondias pinnata, Trapabispinosa (green) and Ziziphus mauritianashowed about 50% inhibition. Aeglemarmelos, Annona squamosa, Annona reticulata,Feronia elephantum, Physalis peruviana andSyzygium jambos showed low activity (< 50%inhibition). Discussions. To date there has been noreport on Angiotensin I-Converting Enzyme inhibitory activities ofthese underutilized minor fruits of West Bengal, India. During ourstudy no correlation could be established between the % ACE inhibitionand the total phenol or flavonoid content of these fruit extracts. So,it appears that non-phenolic components may also be responsible forACE inhibitory activity. In our investigation we tried to establishthe fact that the consumption of these underutilized minor fruitsmight have potential in managing cardiovascular diseases.

The study was conducted to characterize the variations in physical characters and some important feather and skin mutations observed in different populations of native chickens of West Bengal and Sikkim, India. The data encompassing eight different phenotypes such as, naked neck chicken, frizzled chicken, muffed/bearded chicken, creeper chicken, crested chicken, rumpless chicken, feathered shank chicken and fibromelanosis chicken, were collected from six districts of West Bengal and two districts of Sikkim. Seven qualitative traits such as colour of the egg shell, feather, skin, shank, comb and earlobe as well as the type of feather, and three quantitative traits such as shank length, egg weight and body weight, were assessed in a total of 2 170 fowls of both sexes. The data were analysed statistically using descriptive statistics, the differences in means were compared using Duncan's multiple range test and χ2 was used for non-parametric characters. Each of the populations had multiple variants and mixed feather colours were seen in most of the chickens while the feather, skin and shank colours were all black in fibromelanosis chickens. The shank colour was predominantly blue, followed by yellow and white. The skin colour in most of the chickens was white. Most of the chickens had a single comb (except for the crested chicken). The highest body weight was observed in the desi chicken while the rumpless chicken weighed the least. The egg-shell colour varied between cream and light brown in all the flocks except for the fibromelanosis chicken whose egg-shell colour was tinted bluish. The highest recorded egg weight was observed in the naked neck chicken, whereas the hatchability and egg weight were the lowest for the rumpless chicken. In the recent years, it has been observed that there is a significant reduction in the population of native chickens. This may be attributed to the restocking with Rhode Island Red and synthetic Kruilor chickens following the avian influenza outbreaks in the region. Hence, immediate steps need to be taken to preserve whatever is left in the native chicken ecotypes in the region.
