黑豚性成熟早。一般母豚40?60日齡、公豚70日齡就有性征表現,但母豚最好在70日齡后再配種繁殖。配種時應選擇體態豐滿、骨粗壯、眼明亮、毛色光亮、皮膚柔軟有彈性、性器官發育正常的種豚進行交配。母豚性周期為16天,發情持續時間為1?18小時,平均為9小時。交配后母豚陰道口有膠樣栓塞和分泌混合物,根據栓塞物的有無可判斷黑豚是否交配成功。一般情況下,原種繁殖采用一公一母交配法。大群飼養時,多采用2?3只母琢,放入1只公豚進行交配,但必須注意不要同時放入2只以上公琢,否則會引起爭斗,影響交配。母豚配種方法有兩種,一是母膝產仔后半天內配種可提高繁殖率,二是產仔斷奶后即配種可提高配種成功率。母豚妊娠期為56?68天,每胎產仔數為3?5只,多的可達6?9只。年產5?6胎,一只母豚年可循環繁殖40?60只。少量引種即可自繁自養。妊娠期間,除了提高飼料的數量和質量外,場地要保持安靜、清潔,閑雜人員不能隨意出入。要保證日糧的新鮮,少喂多餐。妊娠后期要在籠內放置干草,讓母豚 營巢準備分娩。仔豚出生后即哺乳,3?5天開始采食飼料,哺乳期夏季為15天,冬季為20天,斷乳后應分開飼養,同時,還應注意母體產仔后對幼體的護理工作。哺乳期應增加母豚的飼料營養。胃黑膝繁殖率高,免疫力強,種豚利用年限為3年,在飼養過程中無需免疫接種,也很少用藥物防治。
