حققت هذه الدراسة في التأثيرات الوقائية للكبد والكلى للإضافة الغذائية لخميرة الخبز (Saccharomyces cerevisiae) في فراخ الدجاج حديثة الفقس على مدى فترة تجريبية مدتها 14 يومًا. تم توزيع 120 فرخًا عشوائيًا إلى أربع مجموعات متساوية مع ثلاثة تكرارات لكل مجموعة موزعة على 12 قفص (10 فراخ بكل قفص): مجموعة التحكم التي تتلقى نظامًا غذائيًا أساسيًا بدون إضافة خميرة، وثلاث مجموعات علاجية تتلقى أنظمة غذائية أساسية مدعمة بنسبة 2% (Y1) و4% (Y2) و6% (Y3) من خميرة الخبز لكل كيلوجرام من النظام الغذائي على التوالي. تم قياس المؤشرات الحيوية لوظائف الكبد بما في ذلك الفوسفاتاز القلوي (ALP) وناقلة أمين الألانين (ALT) وناقلة أمين الأسبارتات (AST) والبيليروبين الكلي (T.bilirubin) إلى جانب مؤشرات وظائف الكلى بما في ذلك اليوريا والكرياتينين وحامض اليوريك. أظهرت النتائج أن إضافة خميرة الخبز حسنت بشكل كبير ملفات إنزيمات الكبد، حيث أظهرت مجموعتا Y1 و Y2 انخفاضات ملحوظة في مستويات ALT و AST مقارنة بمجموعة التحكم (p<0.05). أظهرت مجموعة Y1 أفضل النتائج مع انخفاض مستويات ALT من قيم التحكم (17.01-22.31 U/L) إلى 12.51-16.05 U/L، وانخفاض مستويات AST من 45.2-50.5 U/L إلى 28.91-37.23 U/L. أظهرت معلمات وظائف الكلى تحسنًا كبيرًا في المجموعات المدعمة بالخميرة، خاصة في Y1 و Y2، حيث انخفضت مستويات اليوريا من 9-13 مجم/ديسيلتر (التحكم) إلى 3-6 مجم/ديسيلتر و4-9 مجم/ديسيلتر على التوالي. كانت مستويات الكرياتينين أقل بشكل ملحوظ في مجموعات العلاج، حيث أظهرت Y1 قيمًا تتراوح بين 0.03-0.08 مجم/ديسيلتر مقارنة بقيم التحكم 0.10-0.14 مجم/ديسيلتر. انخفض البيليروبين الكلي تدريجيًا مع زيادة إضافة الخميرة، ليصل إلى 0.7-1.0 مجم/ديسيلتر في Y3 مقارنة بـ 1.2-1.5 مجم/ديسيلتر في مجموعة التحكم. تشير هذه النتائج إلى أن إضافة خميرة الخبز بتركيزات 2-4٪ تعزز بشكل فعال وظائف الكبد والكلى في فراخ الدجاج حديثة الفقس، مع تطبيقات محتملة في إدارة صحة الدواجن.
