“…The results of this study reinforce the findings of previous researchers (Sada, 1968;Flores, 1971;Bourdon and Brinks, 1983;Larsson and Berglund, 2008;Grossi et al, 2016) stating that CI is one of the main factors contributing to population growth in beef production. Also, it is almost (approximately) in line with the findings of Olmo et al (2016) from Cambodia and Ibragimov (2016) from Malaysia.…”

This study aimed to determine the contribution of shortening the calving interval to the growth of the beef cattle population in Indonesia. It used panel data from the 2013–2016 time series and cross-sectional data from 24 districts in South Sulawesi. The variables observed were population growth (PG), productive cows (PC) which have the potential to give birth and calving interval (CI). The data were analyzed by regression of panel data using software-reviews 8. The results showed an average length of CI of 28.18 months. PC gave a positive contribution of 0.003% to PG but was not significant (p > 0.05), while CI contributed negatively to PG by -0.028% and was significantly (p < 0.05) for PG. A 1% increase in CI could decrease PG by 0.028%. On the contrary, any decreased or shortening by 1% of CI could raise PG by 0.028%. Without shortening CI, PG decrease. The shortening of the calving interval on the growth of the beef cattle population in Indonesia can be done by up to 45%, from 28.18 ±4.12 to 15.15 ±4.12 months and PG increased about 1.311% from 5.633% to 6.944%. The key to shortening CI is a change of maintenance system, from extensive to semi-intensive, and control of the mating process. Breeders should limit the length of the weaning period and maximize conceptions during the mating period.

“…CI-related studies have, at least, been done on beef cattle and dairy cattle in different countries (Sada, 1968;Flores, 1971;Bourdon and Brinks, 1983;Larsson and Berglund, 2008;Grossi et al, 2016). CI is assumed to be one of the growth factors in meat and milk production.…”
