FACTORS EFFECTING MEDICINALS PLANT SUPPLEMENTATION ON SOME BLOOD PARAMETERS OF KARADI LAMBS . 3- Effect of different levels of rumen undegradable nitrogen

Abstract

The effect of two levels of rumen undegradable nitrogen (7 and 10 g UDN / kg DM ) fed with two levels of Nigella sativa (0 and 7.5 g NS / kg DM) on the diurnal patterns of plasma growth hormone (GH) , serum sugar (SS) , serum uric acid (SUA)serum urea nitrogen (SUN) concentration during 24 h post morning feeding were investigated . Twenty four individual Karadi male lambs were used .They were weighing approximately 34+1.22 kg and 7 months of age. The diets were formulated to be given a 40 parts NaoH-treated barley straw DM to 60 parts concentrate DM. All diets were associated with post- prandial decreases in SS, GH, SUA and SUN concentration during the first 6 h post morning feeding . Lambs fed high level of UDN significantly reduced blood sugar (BS) and increase blood urea nitrogen (SUN) as compared with those fed low level of UDN. Whereas ,level of UDN had no effect on GH and SUA. The results also indicated that the lambs fed diets supplemented with NS significantly increased SS, GH and SUA and reduced SUN as compared with those fed diets without NS .
