The study was conducted of the Ruminant Station belonging to the Directorate for Agricultural Research / Ministry of Agriculture Research Station. The aim of the study is to determine the genotype of the Calpastatin genes and the relationship between genotypes with a number of qualities characteristics of carcasses goats of local Cypriot and bred crosses. The study showed as regarding the genotypes that superiority of genotype MN on MM genotype in the studied traits : percentage of collagen solubility in LD muscle, percentage of myofibril and sarcoplasma proteins solubility, Sarcomere length, MFI of LD and SM muscles. While genotype MM superiority on genotype MN in the studied traits :the total collagen in LD , IS muscle , percentage of collagen solubility in SM muscle, shear strength in LD muscle, MFI in IS muscle .It can be concluded from this study of gene expression for each of the Calpastatin, that is possibility of adoption of in the development of plans for genetic improvement in goats and a snap election for the animals operations, depending on the genetic composition of the gene studied without resorting to animal husbandry for Reconstruction and wide and then resort to the elections, and this leads to get the economic return and reduce the costs of education. This study can be applied to quantitative animals feature using these same genes to be results more comprehensive as well as possible that experience female goats.

تأثير التركيب الوراثي لجين الكالبستاتين على الصفات النوعية للحوم ذكور الماعز المحلي والقبرصي وتضريباتهما
المستخلص
أجريت الدراسة من محطة المجترات تابعة لهيئة البحوث الزراعية / وزارة الزراعة. والهدف من هذه الدراسة هو تحديد التركيب الوراثي لجين Calpastatin علاقته مع عدد من خصائص صفات ذبائح ذكور الماعزالمحلية و القبرصية وتضريباتهما. وأظهرت الدراسة على النحو فيما يتعلق المورثات التي تفوق التركيب الوراثي MN على MM الوراثي في الصفات المدروسة: نسبة ذوبان الكولاجين في العضلات LD، نسبة ذوبان بروتينات الميوفيبريل والبروتينات العضلية ، وطول الساركومير ، ودليل تكسر الليفات العضلية للعضلات LD و SM. في حين الوراثي MM التفوق على MN الوراثي في الصفات المدروسة: الكولاجين الكلي فيعضلة LD، والنسبة المئوية للذوبان الكولاجين في SM ، قوة القص في العضلات LD، دليل تكسر الليفات العضلية في عضلة IS. يمكن أن نستخلص من هذه الدراسة في التعبير الجيني لكل من Calpastatin، وهذا هو إمكانية اعتماد في وضع خطط للتحسين الوراثي في الماعز واجراء انتخابات مبكرة لعمليات الحيوانات، اعتمادا على التكوين الجيني للجين المدروس دون اللجوء إلى تربية الحيوانات لفترات تربية طويلة ثم اللجوء إلى الانتخابات، وهذا يؤدي إلى الحصول على العائد الاقتصادي والحد من تكاليف التعليم. ويمكن تطبيق هذه الدراسة على الصفات الكمية للحوم الماعز وباستخدام نفس هذه الجينات لتكون النتائج أكثر شمولا وكذلك ممكن أن تجربة إناث الماعز.
