Gonadal hormones level and morphometric traits in cow deliveres twin and single calves
Abstract: The objectives of
study were to investigate follicle stimulating hormone (FSH) and luteinizing
hormone (LH) level in four groups beef cow composed of Ongole Grade cow
delivered twinning calves (OGT), Ongole Grade cow delivered single calf (OGS),
Simmental crossbred cow delivered twinning calves (SCT) and Simmental crossbred
cow delivered single calf (SCS). Morphometric traits included body weight,
heart girth, body length, shoulder height, and abdominal circumference were
taken from cows. Cows were reared by farmers in Grobogan and Kendal Regency,
Central Java. Blood serums of cows were taken at estrus. FSH and LH
concentration were measured with enzyme linked fluorescent assays (ELFA)
technique.FSH and LH concentration were compared between OGT, OGS, SCT, and
SCS. Result showed that there were no significant difference of FSH and LH
concentration between OGT and OGS, between OGT and SCT, between OGT and SCS.
There were no significant difference between OGS and SCT, and OGS and SCS.
There were no significant difference between SCT and SCS. Low concentration of
FSH and LH in all cows was related to suckle period, when prolactin
concentration was inversely related to FSH and LH concentration.
