The study was carried out to understand the effect of various concentrations of cholesterol loaded cyclodextrin (CLC) on cryosurvivability of buffalo spermatozoa. Twenty four ejaculates with mass motility GT= 3+ from 4 bulls (6 from each bull) were collected as per standard procedure. Each ejaculate was split into four groups viz., Group I (control: extended with Tris-egg yolk-glycerol extender upto 80*106 sperm/ml), Group II (treated with CLC 1 mg/ml), Group III (treated with CLC 2 mg/ml) and Group IV (treated with CLC 3 mg/ml). Semen samples of Group II, III or IV were incubated with CLC at 37 deg C for 15 minutes for the entry of cholesterol into sperms and finally diluted upto 80*106 sperm/ml. The results revealed that post-dilution and after freezing at 0.7 and 30 days of cryopreservation motility, live and dead, acrosomal integrity and hypo-osmotic swelling test were significantly (P LT 0.05) higher in Group III as compared to all other groups. However, significantly (P LT 0.05) higher percentage of abnormal sperm was observed in control group as compared to other groups. Therefore, addition of CLC 2 mg/ml in extender during buffalo semen cryopreservation has beneficial role in improvement of semen quality.

The present study was undertaken (1) to characterize the FA composition particularly on the concentration of conjugated linoleic acid (2) to investigate of physicochemical properties of Anatolian water buffalo milk, and from six different provinces in Turkey. The fat amount in water buffalo milk samples were in the range of 5.97+-0.30 percent to 9.19+-0.57 percent and the mean fat was 6.96+-0.25 percent. The main individual FA in water buffalo milk were in the order 16:0, 18:1 cis-9, 14:0, and 18:0. The CLA, bovinic acid (cis-9, trans-11), represented 1.09+-0.06 in water buffalo milk. Saturated fatty acids (SFA) were the potent fraction in water buffalo milk fat (70.63+-0.7), MUFA and PUFA were 29.37+-0.7 and 0.2+-0.03, respectively. The data exhibit statistically differences (P LT= 0.05) in the proportions of individual FA were detected among different provinces in Turkey. Anatolian water buffalos were poor in terms polyunsaturated FA compared to other water buffalos from different countries. Therefore, these results may provide useful information about the nutrient composition of buffalo milk and further studies are warranted to improve the technological and nutritional characteristics of Anatolian buffalo milk.
