Extract

The plasma urea nitrogen (PUN) can be an indication of the quantity and degradability of the protein consumed. The high serum concentration of PUN may reduce fertility by local toxic effect on either the sperm, the ovum or the developing embryo (Jordan and Swanson, 1979). The objective of this study was to investigate the effect of high concentration of PUN following the increase of crude protein (CP) intake on ovarian response and fertilisation rate of superovulated ewes.
