Effect of non-protein nitrogen in the ration on ram semen quality

This study was conducted on 20 rams, 6-8 months old. Semen was collected from all rams once weekly for 8 weeks after 4 months of different feeding treatments. The results revealed an improvement in the physico-chemical characteristics of ram semen after feeding ammoniated rice straw with or without alfalfa hay compared with untreated rice straw. It was concluded that ammoniated rice straw with 3\% anhydrous ammonia in the ration can be recommended for feeding growing rams without any harmful effect on semen quality.
