Hair Whorl and Its Relationships with Body Weight of Khao Lamphun Cattle
This study aimed to investigate phenotypic relationships between hair whorl patterns and body weight in Khao Lamphun cattle raised in Phayao Livestock Research and Breeding Center for selection as sacred oxen in the royal ploughing ceremony. Two hundred and thirty-five of Khao Lamphun female cattle were used. The first study was to determine phenotype of hair whorl patterns on the body of Khao Lamphum cattle. The most found was facial hair whorl (Kwan Nar, 94.57% then back hair whorl (Kwan Lung, 88.47%), neck hair whorl (Kwan Tapatub, 64.40%) occipital hair whorl left (Kwan Taddokmai Say) 41.35%, occipital hair whorl right (Kwan Taddokmai Kwa 29.83%) armpit hair whorl left (Kwan Rukra Say, 3.72%) and armpit hair whorl right (Kwan Rukra Kwa, 2.03%). The second study was to evaluate the relationship between cows on morphological appearance with body weight at birth and at 200 days old (weanine). Khao Lamphun cattle without facial hair whorl had birth weight and weight at 200 days old (17.82±1.67 (16) kg and 82.88±13.92 kg) not differed (P=0.05 and P=0.51) from those with facial hair whorl (17.17±1.84 (279) kg and 80.70±13.30 kg). Cattle without back hair whorl had birth weight (17.62±1.81 (34) kg heavier than (P=0.07). but had weight at 200 day (83.71±13.64 kg) not differed (P=0.11) from those with back hair whorl (17.05±1.78 kg and 80.40±13.27 kg) Cattle without neck hair whorl (Kwan Tapatub) had birth weight at 200 days (17.00±1.80 kg and 81.24 ±13.48 kg) not differed (P=0.32 and P=0.95) those with neck hair whorl (17.19±1.79 (105) kg and 81.15 ±13.40). The results showed no relationship between the appearances of hair whorl and body weight of Khao Lamphun cattle raising at Phayao Livestock Research and Breeding Center.
