Zusammenfassung:Introduction- Study the effects of the castration on skeletal muscle. Synthesis of facts- Physical and chemical muscle characteristics of 90 males, females and males rabbits castrated at three days were studied after slaughter when 14 weeks old. Longissimus dorsi muscle was analysed. LD chemical characteristics were insignificantly modified by castration. LD muscle was significantly more tender for females and castrated males than for entire males. Conclusion- The castration affects internal structure of skeletal muscle of rabbits slaughtered at 14 weeks of age.Original Abstract: Introduction- Etude des effets de la castration sur Le developpement du muscle squelettique. Synthese des faits- Les caracteristiques physicochimiques du muscle squelettique de 90 lapins males, femelle et males castres a trois jours et sacrifies a l'age de 14 semaines ont ete determinees. Les mesures ont porte sur Le muscle longissimus dorsi (LD). Les resultats montrent que la teneur en lipides intramusculaires sont peu modifiees par la castration. En revanche, chez les lapins castres, la force de resistance des tissus musculaire et conjonctif areolaire a la rupture par cisaillement est significativement plus faible que chez les lapins males entiers. Conclusion- La structure interne Du muscle a ete modifiee par la castration chez les lapins sacrifies a 14 semaines.
