چکیده مقاله :
هدف: از مهم‌ترین هزینه‌‌های پرورش گوسفند، خوراک و بخش متراکم جیره غذائی است. این پژوهش به منظور بررسی تاثیر نرخ متفاوت کنسانتره، علوفه در بره‌‌ها انجام شد. مواد و روش‌ها: تعداد 27 رأس بره نر نژاد لری بختیاری با میانگین سن 75 روز و وزن 26 کیلوگرم انتخاب و در سه تیمار و نُه تکرار تقسیم‌بندی شدند. تیمار یک نرخ کنسانتره به علوفه 45: 55، تیمار دو 70: 30 و تیمار سه 85: 15 بود و تغذیه به صورت انفرادی در دو نوبت صبح و عصر انجام شد. پس از پایان دوره 100 روز، خون‌‌گیری انجام و کلیه بره‌‌ها ذبح شدند. بیضه‌‌ها از کیسه بیضه خارج و پس از اندازه‌‌گیری فراسنجه‌‌های مورفومتری، نمونه بافت بیضه با ابعاد 1×1 سانتی‌متر در محلول فرمالین 10% فیکس و مقاطع بافتی تهیه شد. یافته‌ها: نتایج نشان داد که نرخ کنسانتره، علوفه در فراسنجه‌‌های ماکروسکوپی بافت بیضه تفاوت معنی‌‌داری ایجاد کرد (05/0˂P). وزن بیضه در تیمار سه در بره‌‌ها کاهش یافت. در این تیمار ضخامت پوشش لوله‌‌های اسپرم‌‌ساز، قطر لوله، قطر لومن و مساحت لوله کاهش داشت. همچنین نرخ هماتوکریت، شمار گلبول‌‌های قرمز و هموگلوبین این تیمار به طورمعنی‌‌داری بالاتر از سایر تیمارها بود (05/0˂P). نتیجه‌‌گیری: افزایش درصد کنسانتره بیش از 70 درصد تاثیر منفی را بدنبال خواهد داشت.
Purpose: One of the most important costs of sheep breeding is feed and the concentrated part of the ration. This research was conducted in order to investigate the effect of different rates of concentrate and fodder in lambs. Materials and methods: 27 Lori Bakhtiari male lambs with an average age of 75 days and a weight of 26kg were selected and divided into three treatments and nine replications. Treatment one was 55:45 concentrate to fodder, second treatment was 70:30 and third treatment was 15:85 and feeding was done individually in morning and evening. After the end of the 100-day period, blood sampling was done and all the lambs were slaughtered. The testicles were removed from the scrotum and after measuring the morphometric parameters, the testicular tissue sample with dimensions of 1x1cm was prepared in 10% formalin solution and tissue sections were prepared. Findings: The results showed that the rate of concentrate and fodder made a significant difference in the macroscopic parameters of testicular tissue (P˂0.05). The weight of the testis in the treatment of three lambs decreased. In this treatment, the thickness of the coating of spermatogenic tubes, tube diameter, lumen diameter and tube area decreased. Also, the rate of hematocrit, red blood cells and hemoglobin of this treatment was significantly higher than other treatments (P˂0.05). Conclusion: increasing the percentage of concentrate more than 70% will have a negative effect.
