چکیده مقاله :
The aim of the present study was to evaluate the influence of roasted soybean and sunflower meal on the consumption and growth performance of lambs from the Blackhead Pleven Breed. The results indicated that the addition of roasted soybean caused the lambs to grow significantly faster than those fed sunflower meal (P<0.01). Adding roasted soybean to the feed caused lambs to intake significantly less maize and roughage, while intake more protein feed at the same time. Combined with the significantly higher growth rate (P<0.01), lambs receiving roasted soybean exhibited lower expenditure of dry matter, concentrated feed and raw protein for 1 kg of growth, compared to lambs who were fed with sunflower meal (P<0.01). The intake amount of dry matter had a significant effect on the average daily gain in lambs consuming roasted soybean, with a high correlation coefficient (r=0.645). In both groups of lambs, raw protein and FUG feed units for growth intakes significantly affected the animals’ growth performance.
هدف مطالعه حاضر ارزیابی تأثیر کنجاله سویا و آفتابگردان برشته شده روی مصرف و عملکرد رشدی برههای نژاد پلهون سرسیاه بود. نتایج مشخص کرد که افزودن کنجاله سویای برشته به خوراک سبب شد تا برهها رشد سریعتری را نسبت به آنهایی که کنجاله آفتابگردان مصرف میکردند، داشته باشند. افزودن کنجاله سویای برشته به خوراک سبب شد تا برهها مقدار کمتری از ذرت و علوفه خشک را مصرف کنند، در حالیکه خوراک پروتئینی بیشتری در همان زمان مصرف شد. علیرغم سرعت رشد بیشتر (01/0P<) در برهها دریافت کننده سویای برشته شده، این برهها مصرف کمتری از ماده خشک، خوراک کنسانتره و پروتیین خام برای 1 کیلوگرم از افزایش وزن را در مقایسه با برههای تغذیه شده با کنجاله آفتابگردان نشان دادند (01/0P<). مقدار مصرف ماده خشک اثر معنیدار (با ضریب همبستگی بالا، 647/0r=) روی متوسط افزایش وزن روزانه در برههای مصرف کننده کنجاله سویای برشته شده داشت. در هر دو گروه برهها، مصرف پروتیین خام و واحدهای خوراک برای رشد به طور معنیداری روی عملکرد رشدی حیوانات اثر گذاشت.
