Abstract AR
استخدم في هذه الدراسة عدد 228 رأس من الأبقار (البقارة–الكنانة–البطانة–هجين الفريزيان مع البطانة و الكنانة) و ذلك لمعرفة التنوع الوراثي في 5 مواقع اليلية لبروتين اللبن–كازين– as1-casein (CSN1S1), as2-casein (CSN1S2), B-casein (CSN2), k-casein (CSN3) B-2actoglobulin (LGB) استخدمت طريقة التفريد الكهربي لفرز الأليلات.
أوضحت الدراسة أن كل المواقع الأليلية يوجد بها تحورات (polymorphism) جينية.
كما أسفرت الدراسة عن وجود اليلين جديدين هما CSNIS1 * 1 و CSNIS2*X و قد وجد الأول في كل من أبقار البطانة و البقارة بينما وجد الثاني في كل السلالات التي درست.
Abstract EN
The genetic variation at five milk protein loci asl-casein (CSN1S1), as2- casein (CSN1S2), p-casein (CSN2), K-casein (CSN3) and p-lactoglobulin (LGB) was investigated in 228 animals belonging to four dairy populations well adapted to prevailing climatic conditions of Sudan..
Bos indicus (Butana, Kenana and Baggara) and Bos indicus (Kenana or Butana) X Friesian (KBF) were studied using isoelectric focusing technique for loci characterization.
All loci were polymorphic and two new variants were detected at CSN1SI and CSN1S2.
The CSN1S1*/ variant was shown by the Butana and Baggara cattle, while CSN1S2*X variant was observed in all populations under the study.
Milk protein loci, being positively selected loci, can also provide information about the occurrence of germplasm particularly useful for breeding strategies and production improvements
