Analysis of seasonal effect on Korean native cattle (Hanwoo) birth weight
Recently, summer temperatures have frequently been abnormal in Korea owing to global warming. In summer, a decrease in feed intake rate and biological activity were observed in Hanwoo (Korean Native Cattle), leading to lower production rate...

Recently, summer temperatures have frequently been abnormal in Korea owing to
global warming. In summer, a decrease in feed intake rate and biological
activity were observed in Hanwoo (Korean Native Cattle), leading to lower
production rates in the industry. However, the precise scale of damage was not
reported as with other animals of economic value. This study was conducted to
investigate the effects of birth season on birth weight in Hanwoo. Data were
collected from 100 local breeding farms from 2016 to 2019. A total of 41,081
Hanwoo calves were classified and analyzed by sex, year, month, and season
(March–May, spring; June–August, summer;
September–November, fall; and December–February, winter) of birth.
The birth weight of Hanwoo calves differed according to birth month. The average
birth weight of male calves was 30.47 kg and that of female calves was 28.16 kg.
Hanwoo birth weight was the highest in March-born calves and the lowest in
July-born calves. The birth weights of calves born in February, March, April,
November, and December were significantly larger than those of calves born in
July. In addition, the birth weight of Hanwoo calves from the summer was
significantly lower than that of calves born in other seasons. Furthermore,
Hanwoo steer slaughter age showed a negative correlation, whereas carcass weight
had a positive correlation with birth weight. In the beef cattle industry, birth
weight is a very important economic characteristic that is related to growth
rate. These data will contribute toward planning the reproduction of Hanwoo and
analysis of changes in characteristics of economic value owing to high
temperatures. |
