中文描述母豬應該在5-7個月之後達到青春期, 然而多數卻在9個月還未開始。青春期的早晚會受到生育, 遺傳,季節, 營養, 管理因子和居住環境的影響.從延遲開始就把異常的母豬一起圈在外頭或限制住牠們。母豬在靠近成熟發育的豬群會較快展現發情期。
英文描述Gilts should reach puberty at 5-7 months of age, however many have not started to cycle by 9 months. Age at puberty may be influenced by breed, heredity, season, nutrition, management factors and housing, with the onset delayed by keeping gilts in outside lots or in confinement. Gilts placed near sexually mature breeding stock showed estrus sooner.
