Abstract

The purpose of this research was to study the situation of dairy cow raising in Phayao province and to compare number of day inserted Controlled Internal Drug Release (CIDR) estrous synchronization method in dairy cow. Study 1, the situation of dairy raising information was collected from all available farmers in province by interviewing. Data were analyzed and explained the results by using descriptive statistics. Most farmers were male (83.33%) and had age between 40-60 years old (66.67%). Most of them graduated from primary school (33.33%) and undergraduate (33.33%). Farmers raised dairy cattle as a main occupation (91.67%) had experienced in dairy farming for 3-4 years (33.33%). Most farmers had pasture for feeding their dairy cows (91%) and used concentrate feeds from cooperatives (100%). All farmers had pedigree records (100%). The main problem of raising dairy cow was their cows did not show estrus 60 days after calving (46.47%). Study 2, comparison among three CIDR estrous synchronization schemes (7, 9 and 11 days) in cows that did not show estrus within 60 days after calving. Twenty cows were used in this study, group 1 inserted CIDR for 7 days (n=7) group 2 CIDR for 9 days (n=7) and group 3 CIDR for 11 days (n=8). The result showed that the in 7, 9 and 11 days groups have progesterone level 23.04±1.70, 21.89±5.24 and 22.38±8.82 ng/ml, respectively (P>0.05). At the remove CIDR day the progesterone level in 7, 9, 11 days groups were 17.21±6.74, 25.65±13.82 and 23.81±6.52 ng/ml, respectively (P>0.05). At Artificial insemination (AT) day the progesterone level in 7, 9, 11 days groups were 11.16±1.66, 9.83±2.11 and 8.00±4.79 ng/ml, respectively (P>0.05). Result of the estradiol hormone levels of insert day in 7, 9, 11 days group were 4.26±2.01, 4.35±0.67 and 4.75±0.68 ng/ml, respectively (P>0.05). At the remove CIDR day the estradiol hormone levels in 7, 9, 11 days group were 5.09±2.12, 4.72±0.78 and 4.66±1.61 ng/ml, respectively (P>0.05). At AI day the estradiol hormone levels in 7, 9, 11 days group were 4.23±1.37, 4.90±0.92, 5.65±3.16 ng/ml, respectively (P>0.05). Conception rates at 1st and 2nd after AI of cows in all experimental groups were not significantly different (P>0.05).
