A total number of 32 of Ossimi lambs averaged 29.25 ± 2.02 kg and 4 months old were used in this experiment to compare the effects of dietary supplementation of inorganic selenium (sodium selenite), organic selenium (Se-yeast) and Nano-Se particles on nutrients digestibility, nutritive value, productive performance and serum biochemical indices of lambs. The animals were allocated into four equal groups (8 lambs each). The lambs of control group were fed on basal diet containing 0.17 mg Se/kg dry matter (DM). The treated lamb groups fed on the same basal diet, in which Se at 0.30 mg/kg DM was provided as sodium selenite (SS), selenium yeast (SY) and Nano-Se particles (NS). The results showed that digestibility of DM was higher (P<0.05) for lambs fed SS, SY and NS than those fed control. Digestibility of OM, CP, CF, EE, NFE and the values of digestible crude protein (DCP) and total digestible nutrients (TDN) were increased (P<0.05) for lambs fed SY and NS compared with those fed SS or control. Averages of final body weight (FBW) were increased (P<0.05) for lambs fed SY and NS compared with those fed SS and control. Average of FBW was greater (P<0.05) for lambs fed NS than those fed SY. The averages of daily gain (ADG) were increased (P<0.05) for lambs fed SS, SY and NS vs. those fed control with significant (P<0.05) differences among treatments. No significant differences were detected in averages of feed intakes of Alfalfa, DM and total DM (TDM) for lambs fed SS, SY and NS vs. control. While, the intakes of DCP and TDN were greater (P<0.05) for lambs fed SS, SY and NS vs. those fed control with significant (P<0.05) differences among treatments. The averages of feed conversion (FC) of DM (FC-DM), DCP (FC-DCP) and TDN (FC-TDN) were improved (P<0.05) for lambs fed SS, SY and NS vs. those fed control. The highest values of productive performance parameters (FBW, ADG, DCPI, TDNI, FC-DCP and FC-TDN) were noticed for lambs fed NS followed by those fed SY and then SS and control. Lambs fed SY and NS had higher (P<0.05) values of serum total protein and globulin than those fed SS or control. Also, there was an increase (P<0.05) in serum glucose concentrations for lambs fed diets SS, SY and NS vs. control, with higher levels (P<0.05) in NS than in SS and SY. No significant differences were noticed in serum concentrations of albumin, cholesterol, alanine transaminase (ALT) and aspartate transaminase (AST) enzyme activities. Serum total antioxidant capacity (TAC) concentrations, glutathione peroxidase (GSH-Px) activity and testosterone levels were increased (P<0.05) for lambs fed SS, SY and NS vs. control. Higher (P<0.05) levels of TAC, GSH-Px and testosterone levels were observed for lambs fed NS than those fed SS and SY. It could be concluded that dietary supplementation of Nano-Se was more effective than sodium selenite and Se-yeast to improve nutrients digestibility, feeding values, growth performance, some serum metabolic indices, antioxidant status and reproductive efficiency of male lambs.

This study was designed to investigate the effect of garlic powder (GAP) or cumin powder (CUP) supplementation in growing lambs ration on nutrients digestibility, rumen liquor parameters, blood constituents and growth performance,. Eighteen of growing Barki lambs (averaged 5-6 months of age and weighted 27.5 ± 0.90 kg) were divided into three equal groups (6 animals each) in a feeding trial lasted 100 days. Animals were fed on basal diet (control) or supplemented with 2% GAP (T1) or CUP (T2) of the concentrate feed mixture. The results showed that apparent digestibility of all nutrients and nutritive values as total digestible nutrients (TDN) and digestible crude protein (DCP) were significantly (P<0.05) higher for lambs fed rations of GAP or CUP compared with those fed the control ration. Ruminal ammonia nitrogen (NH3-N) was increased (P<0.05) for lambs fed rations GAP or CUP compared with those fed the control, however ruminal pH and TVFA’s were comparable among the experimental treatments. The values of N balances and dietary N utilization were increased (P<0.05) for lambs fed GAP supplemented ration compared with those fed control or CUP-supplemented diet. Meanwhile Average daily gain and feed conversion were higher (P<0.05) for lambs fed GAP or CUP than those fed control ration. Dry matter intake was comparable among the experimental treatments. There were no significant differences in plasma albumin and cholesterol concentrations among treatments, while plasma concentrations of total protein, globulin and total antioxidant capacity were higher (P<0.05) for lambs fed GAP or CUP than those fed control ration. Plasma triglycerides concentrations was higher (P<0.05) for lambs fed CUP than those fed GAP or control. Plasma malonaldhyed (MDA) was decreased (P<0.05) for lambs fed rations of GAP or CUP than those fed control ration. There was a decrease (P<0.05) in plasma concentrations of HDL with feeding CUP ration and levels of LDL with feeding GAP compared to feeding the control ration. This study showed that dietary supplementation of either garlic or cumin powder at 2 % significantly improved nutrients digestibility and growth performance in growing lambs, without any adverse effect on rumen fermentation.

This study aimed to evaluate the effects of dietary nano-selenium (Se-NP), nano-zinc (Zn-NP), and their combination, on the performance of Ossimi ewes and their offspring. Twenty-eight pregnant Ossimi ewes were randomly allotted to one of four equal experimental groups. The ewes were fed a basal diet with the addition of 0.3 mg selenium nanoparticles (Se-NP), 30 mg zinc (Zn-NP), or 0.3 mg Se-NP plus 30 mg Zn-NP (SZ-NP)/kg DM. The results showed that nutrient digestibility, nutritive values, milk yield, and fat corrected milk, as well as milk constituents yields, were improved (p < 0.05) for ewes fed Se-NP, Zn-NP, or SZ-NP vs. the control one. As well, lambs’ birth weight, final body weight, and average daily gain were increased (p < 0.05). Serum immunoglobulin G, total protein, albumin, globulin, and glucose values were higher (p < 0.05); however, serum cholesterol level tended to be decreased. Ewes and their respective lambs in the Se-NP, Zn-NP, or SZ-NP groups had lower (p < 0.05) urea concentrations and liver enzyme activity than the control. Thyroid hormones, total antioxidant capacity, and glutathione peroxidase activity were higher (p < 0.05) in the Se-NP-, Zn-NP-, or SZ-NP-fed groups. This improvement was accompanied by favored growth performance, immune function, and overall health in their suckling lambs, with selenium being more effective than zinc. In conclusion, the dietary inclusion of selenium, zinc nanoparticles, or their combination can be an effective strategy to enhance productivity and health in ewes and their offspring.

A total number of 24 Ossimi pregnant ewes averaged 38.06 ± 2.09 kg at 4 -6 weeks of late gestation were used to evaluate the effects of selenium (Se) supplementation upon productive performance, nutrient digestibility, some biochemical indices and antioxidant status of Ossimi ewes and their suckling lambs. They were fed on basal diet (control) supplemented with Se at 0.3 mg as sodium selenite (T1) or Nano Se (T2) /kg DM. The results showed that OM, CP, EE, CF and ADF digestibility were increased (P<0.05) for ewes fed T2 compared to those fed T1 or control. Birth weight, FBW and ADG were improved (P<0.05) for lambs born to ewes fed T1 or T2 diets vs. control. Milk yield, FCM, milk fat yield and milk protein yield recorded higher (P<0.05) values for ewes fed T1 or T2 than the control one. Serum IgG, total protein, albumin, globulin, thyroid hormones, total antioxidant capacity and glutathione peroxidase activity were higher (P<0.05) for both ewes fed T1 or T2 and their lambs when compared to respective control. Serum cholesterol, liver enzymes (ALT and AST) and urea concentrations showed a decrease (P<0.05) for ewes fed T1 or T2 and their respective lambs compared to those fed control one It is concluded that dietary supplementation of nano Se at 0.3 mg/Kg DM to Ossimi ewes was more potent than inorganic Se to improve their nutrients digestibility, productive performance, some serum biochemical indices and antioxidant status, leading to better growth performance and health of their suckling lambs.

Femoral neck fractures are intracapsular fractures that occur in the proximal femur in the area beginning distal to articular surface of the femoral head and ending just proximal to the intertrochantric region. to evaluate the functional outcome of bipolar hemiarthroplasty in patients with intra capsular femoral neck fractures . and to determine the factors affecting the outcome and to see whether bipolar hemiarthroplasty meets desired end result or not; patient will be evaluated using Harris hip score and radiographic assessment. The present work was a retrospective study including twenty patients. These patients were be followed up for minimum five years post-operatively and traced to detect their actual hip function and performance. The early complicated patients would be excluded. The mean age of the patients was 73.4 years. The Harris hip score showed satisfactory results at the end of follow up three patients (15%) had hip scores from 100 to 91 (excellent). eight patients (45%) cases had hip scores90 to 81 (good). Two patients (10%) were rated 80 to 70. (fair), and seven patients (35%) were rated below 70(poor) . The mean Harris hip score at the end of follow up was71.0 (range from 25.0– to97.0) with SD 22.4. It was found that the greater motion at the inner bearing correlated with better clinical results. Therefore the amount of motion at the two interfaces appears dependent on a number of variables and still a topic of debate.

This experiment was carried out to study the effect of selenium yeast (SeY) and/or vitamin E (VitE) supplemented diets which is a commercial antioxidants containing SeY and VitE on productive performance and some blood biochemical parameters of Ossimi ewes and their offspring under two different housing types. Eighty Ossimi ewes in late pregnant period were divided into two equal groups (40 ewes each), the first group averaged 40.38±0.93kg body weight and was settled in semi-opened house with concrete floor and roofed with west-east direction (1st H). While the second group averaged 39.49±1.12kg body weight and was settled in fully shaded house, roofed by single asbestos sheetin and topped with rice straw bales and natural earthen ground with north-south direction (2nd H). Each group randomly divided into four equal subgroups; G1: fed 40% rice straw + 60% concentrate feed mixture (control). G2: fed control + 0.3 mg SeY /kg diet. G3: fed control + 40 mg VitE /kg diet. G4 fed control + 0.3 mg SeY and 40 mg VitE /kg diet. Results indicated that ewes body weight was higher (P<0.05) for ewes of treated groups than untreated (control). Percentage of body weight changes during experimental period increased (P<0.05) from-0.26 to +1.79 % and from +0.18 to +3.69% for ewes treated by SeY plus VitE, in 1st H and 2nd H, respectively. There was significant (P<0.01) improvement for G4 in feed intakes and feed conversion, milk production and milk composition for ewes received SeY plus VitE compared to control. Data indicated that the supplementation with G4 had significantly (P0.05) differences for all blood constituents' values among groups in the 1st house. While, concentrations of serum total protein, albumin, globulin, glucose and cholesterol were significantly (P<0.05 and P<0.01) higher in the treated groups (G2, G3 and G4) than those in G1 in 2nd house type. Concerning serum AST and ALT values obtained here in were within the normal range for healthy sheep. It was concluded that dietary supplementation with SeY plus VitE could be used for the improvement in productive performance of pregnant and lactating ewes post-lambing without any side effects on the general health. Also, sustenance in the second house type had useful impacts on improving growth rate, feed conversion rate, milk production and some related serum biochemical indicators.
