| Popis: | Extended Abstract Introduction and Objective: The use of agricultural by-products instead of grain seeds in livestock diets has been an important issue for scientific study. One of these products is potato waste that, if properly processed by methods such as ensiling, can replace cereal seeds such as barley in the diet, due to the proper nutritional value of this product, improving animal growth performance, reducing feed costsand prevent food from being wasting. Therefore, the purpose of this study was to investigate the effect of replacing different levels of potato waste silage with barley on growth performance, digestibility, and rumen and blood parameters of fattening lambs. Material and Methods: In this study, 30 Zell and Afshar mixed male lambs with a mean weight of 26±2 kg and mean age of 5.5±0.4 months were used in a completely randomized design (CRD) with 5 treatments and 6 replications for 90 days. The experimental treatments included the control treatment (without potato waste silage) and the treatments containing 25, 50, 75 and 100 potato waste silage replacement of barley seeds (based on dry matter). Results: The results of performance traits showed that there was a significant difference in fattening weight, daily weight gain, dry matter intake and feed conversion ratio between experimental treatments (p |
