الملخص

Selenium found in plants is ideally suited to the animal digestation andmetabolism because it is in the form of selenium acids. Unfortunately, livestock producershave been forced to relyon inorganic selenium sources, such as selenite, in regions where sioland plants produce feed ingrients with low selenium content. In this study, two experimentswere conducted to evaluate the effect of only selenium or synergized with vit E on thereproductive performance of Nubian goats. Twenty two non pregnant goats were selected andkept under indoor ad lib. forageing plus concentrate offered on daily basis at the rate of 1 kgper group. The goats were divided to six groups according to similar body weight basis. Threegroups A, B and C constituting 5, 3 and 3 heads respectively were assigned for eachexperiment. Group A was designated as control, selenium free. Selenium premix wad dosed at0 (devoid), 5 (low) and 10 (high) mg/kg (first experiment) or synergized with vitamin E 0+0(devoid), 5+250( low) and 10+500 (high) mg/kg+ I.U./g (second experiment) twice weekly ,fed in concentrate by dilution to groups A, B and C respectively . Goats' health was observedthroughout the experimental period during gestation and delivery. Blood samples wereanalyzed every three weeks for RBCs count, Hb concentration, PCV, WBCs count andtheir differential lymphocytes. Sera were analyzed for metabolic indicators glucose, totalprotein, albumen, globulin and cholesterol, electrolytes Ca, P and Se and Serum enzymesALT and ALP. Gestation start was assessed by palpation. On delivery, neonate sex, averagebirth and one month weights (kg) were recorded.All experimental goats were healthy althrough the experimental period with normalvoluntary feed intake, behavioural patterns and deliveries. Hematological findings show nonsignificant (p>0.05) differences among all treatments and goups. Values of LS were higherthan those of HS, but always higher (P> 0.05) than the control except for lymphocytes of HS(4.90±2.99). WBCs varied (p>0.05) with different treatments HsHv 17.74±5.05 followed byLsLv17.17±5.51, Ls 14.48±3.45 and Hs 13.42±5.2 when compared to the control(13.55±4.93). Little effect (p>0.05) was imposed on Hb in the diffenent treatments comparedto the control. All serum metabolites values were not significant (P>0.05) compared to thecontrol. The glocuse level was higher (p>0.05) for the treatments Hs (9.25±5.02) and LsLv(8.00±4.98). For total protein, Albumin and Globulin showed a better (p>0.05) reponse to thetreatment with Hs (7.26±0.43), LsLv (3.83±0.49), and Hs (3.81±0.69) respectively comparedto all other treatments. Cholesterol values were higher (p>0.05) for all treatments except withHS. Selenium concentrations, high and low correlates insignificantly (p>0.05) with totalprotein, but HsHv and LsLv correlates significantly (p0.05) mean treatmentdifferences, though Ca showed a better response with HsHv (9.23±0.97). Synergized Sevalues 36.67±32.62 (HsHv) and 36.47±13.73 (LsLv) were the only significant (p0.05) whencompared with the control. Avarge birth and one month weights (kg) of newborns wereascending in values for control, Ls and Hs, wheras same values were descending for control,LsLv and HsHv.The effect of Se alone or synergized with vitamin E on goat reproduction in thisstudy was not significant, deflating positive expectations. The reason was attributed to theeffect imposed on bioavailability and absorption of Se by the quality and quantity of feedsupplied.
