Influence of αS1-casein and κ-casein polymorphism on the curd yield of Italian Mediterranean buffalo (Bubalus bubalis L.) milk

Abstract The influence of αS1-casein (αS1-CN) and κ-casein (κ-CN) polymorphism on the curd yield and 12 other parameters of milk obtained from 89 Italian Mediterranean buffaloes (IMB) was evaluated. IMB milk carrying αS1-CNB and κ-CNX1 variants resulted in a greater curd yield. For these variants, the greater efficiency was attributable to higher content of proteins but not to milk production. In addition, the greater efficiency in curd yield of IMB milk carrying κ-CNX1 (P
