Incorporation field crop residues in rabbit rations

Abstract

Abstract Background In Egypt, the area of Berseem was decreased and wheat area increased which lead to high price of rabbit rations. Using non-traditional feed led to decrease the cost of feeding. The main objective of this study is to replace 50% of Berseem hay (BH) of rabbit rations by agriculture by-products such as Mung bean husks (MBH), soybean vein hay (SBVH), or peanut vein hay (PVH). Method Twenty-four New Zealand White (NZW) rabbits aged 5–6 weeks (584 ± 25 g) were randomly divided into four equal experimental groups. Feeding trial lasted 70 days. Results Except for organic matter (OM) digestibility, treatments had no effect on all other nutrient digestibilites that includes dry matter (DM), crude protein (CP), crude fiber (CF), ether extract (EE), and nitrogen free extract (NFE) and nutritive values {total digestible nutrient (TDN) and digestible crude protein (DCP)}. Instead, 50% of BH by the other alternative source of agriculture by-products had no effect on all carcass parameters measured. However, dressing percentages was improved. Treatments had no effect on albumin, total lipids, triglycerides, total cholesterol, low-density lipoprotein (LDL), glutamic oxaloacetic transaminase (GOT), creatinine, and alkaline phosphatase. Conclusion It can be instead 50% of hay used in rabbit rations with alternative sources of roughage, such as Mung bean husks, soybean vein hay, or peanut vein hay, without any adverse effect on their performance, digestion, carcass characteristics, and blood constituents.
