“…When expressed as percentage of BW, DM intake of sheep fed SGH ranged between 4.0% and 4.5% compared with 3.2% and 4.0% for sheep fed RGH at all stages. This intake is comparable to that of 3.4% and 4.0% obtained from studies using same breed in Oman (El-Hag and Al-Shargi 1998; Mahgoub et al 2000;Al Khalasi et al 2010). Gatenby (1986) suggested that an intake of 3.5% of BW is expected for sheep on moderate-quality diet.…”

Twenty-eight indigenous ewe lambs (6 months of age and 14.4 kg body weight (BW)) were used to evaluate the effect of feeding Sporobolus grass hay (SGH) as the only source of forage on growth, and feed and water intakes. The ewe lambs were randomly and equally allocated to two treatment groups (14 lambs/group). The ewe lambs in group 1 (treatment 1) received SGH, while lambs in group 2 (treatment 2) received Rhodes grass hay (RGH) as the only source of forage. Water was available at all times for both treatment groups. Sporobolus grass was irrigated with brackish water of high salt content (20,000 ppm) and grown in saline desert lands (sabkha) in the United Arab Emirates. The average daily dry matter intake was significantly (P < .05) higher for the animals fed SGH than those fed RGH at all stages. Both water intakes per unit body gain and water intake per unit feed intake were significant (P < .05) between the two treatments group at all stages. Average daily gain did not differ significantly (P > .05) between the two groups at all stages. From these data, we conclude that SGH can replace Rhodes hay in sheep diet without significant effect on sheep performance.

“…The T8, T4 and T6 showed a higher (P<0.05) leaf to stem ratio as compared to the control treatment (T1). Al Khalasi et al (2010) reported that stems represent 70%, leaf sheaths 15.5%, leaves 12.5% and 1.5% ears. Mostafa et al (2010) reported that fodder yield for different sorghum genotypes ranged from 12.4-23.7 ton/feddan however, leaf to stem ratio ranged from 0.13 to 0.35.…”

“…Third, concentrations above 9,000 ppm should not be fed to livestock. Al Khalasi et al (2010) reported that rumen micro-organisms could convert nitrate into nitrite and finally to ammonia. Besides, the microbes can adapt to a constant level of nitrate in the feed and make the nitrate conversion cycle more efficient.…”

It was applied in two experiments (Agronomy and fodder evaluation experiment and animal growth experiment) to determine the response of sorghum quality and consequently the animal performance to the application of combined N and P fertilizer in newly reclaimed soil. The first experiment was for evaluating sorghum fodder (Sorghum bicolor L.) that sorted with nine treatment combinations (from T1 up to T9) comprising of three nitrogen (N) and phosphorus (P) fertilizers levels (N 80.4 , N 100.5 and N 120.6 kg/feddan vs. P 20.2 , P 30.2 and P 40.3 kg/feddan) in factorial randomized block design with three replications. The results of the agronomy experiment with considering the ISDMD, NEg and the cost of treatments, showed that two treatments (N 120 P 30 and N 100 P 40 ) could be nominated to the second experiment which was their evaluation as feeds for the growing Barki lambs as compared to control treatment (N 80 P 20 ). So, two treatments and control were sorting again in the next summer season to evaluate their nutritive values by using 15 growing Barki lambs (5 lambs/ treatment) in a completely randomized block design. Lambs were on average 22.83 ± 0.29 kg as the initial body weight and aged 5 months. All animals fed concentrate feed mixture to cover 70% of their growth requirements (Kearl, 1982). However, the experimental fodders were offered ad lib. So the experimental animal groups were allowed for three rations for 85d as follows; R1: CFM + sorghum forage of T1 (N 80 P 20 ) ad lib., (served as a control), R2: CFM + sorghum forage of T6 (N 120 P 30 ) ad lib, and R3: CFM + sorghum forage of T8 (N 100 P 40 ) ad lib. The results indicated that; Average daily gain differed significantly (P= 0.016) being values 158, 185 and 192g for lambs fed R1, R2 and R3, respectively. Animals in R2 and R3 consumed a higher (P=0.042) amount of sorghum compared with the control one. There is a significant effect (P< 0.05) of sorghum treatments on feed conversion ratio (FCR), where sheep fed R1 or R2 had better FCR as g DM/ g gain or g TDN/ g gain than those fed control sorghum ration. However, R1 revealed better FCR as g DCP/g gain as compared with the other groups. The digestibilities of DM, CP and CF were higher (P<0.05) for R2 and R3 compared to the control one. However, digestibilities of EE and NFE were not affected (P>0.05) by the experimental rations. Both R2 and R3 were the better (P<0.05) for both TDN and DCP values as compared with the control ration. Higher (P<0.05) N balance was observed with R2 than control. All lambs retained relatively similar (P>0.05) amounts of calcium. However, higher P content in sorghum of R2 and R3 revealed significantly higher P intake (P<0.05) and also P retained (P<0.05). The revealed insensible water loss (IWL) of the three groups was significantly different being values 144, 172 and 176 g/kg 0.82 for R1, R2 and R3, respectively. The rumen pH value of animal group fed control ration (R1) was significantly (P≤0.001) higher than other groups at all the sampling time. Animals who received R2...

“…Conversely, some studies showed no adverse effect of salt plant on kidney function. Al-Khalasi et al (2010) reported that there were no significant differences in blood urea of Omani sheep fed salt-tolerant sorghum forage or Rhodes grass and El-Bassiony (2013) reported that feeding salt tolerant plants did not have any adverse effects on BUN concentration. In the current study, urea and creatinine concentrations were increased insignificantly throughout the gestation period (Table 5).…”

o study the effect of feeding salt tolerant fodder crops during pregnancy under south Sinai conditions (Ras Sudr station) on some physiological responses of Shami goats, fourteen Shami doe goats aged 2.5-3.0 years old with averaged 25.07± 2.44 kg body weight were used and randomly divided into two equal groups (7 animals each) as follow: The first group (G1) fed berseem hay as control, while the second one (G2) fed a mixture of Atriplex nummularia (50%) + Sorghum bicolor (25%) + Pearl millet (25%). Both groups were supplemented with concentrate feed mixture (CDM). Live body weight changes and daily gain were recorded biweekly. Blood samples were collected from the all animals during dry, gestation (early, mid and late) for the determination of the biochemical parameters, electrolytes and hormones. The results revealed that live body weight and weight gain of control and the treated groups of doe goats were similar. Treated goats had slightly insignificant lower concentrations of TP, AL, GL, A/G ratio, and cholesterol with significant effect of pregnancy on total proteins profile. The mean values of TP, AL and GL significantly decreased (P<0.05) with advancing gestation periods. Glucose and aldosterone concentrations in treated pregnant goats showed significant (P<0.01) decrease as compared to the control animals. The significant interaction between treatment and physiological stage for ALT, ALP enzyme and insulin concentrations was for the reverse effect of each source of variance. While ALT, ALP enzyme and insulin increased by feeding salt tolerant plants but they were decreased by advancing pregnancy stages. Feeding a mixture of salt tolerant plants significantly decreased (P<0.01) the concentrations of urea and creatinine in comparison with control diet with insignificant increased throughout the gestation periods. The concentration of Na was affected significantly (P<0.01) by treatment and physiological status where it showed significant increase in the treated animals during different pregnancy stages. Potassium concentration was increased significantly from dry to reach peak during mid-gestation then declined again during late gestation compared to control animals. These results might indicate that salt tolerant plants could be a feasible solution to minimize the problem of animal feed shortage under arid conditions of Southern Sinai without sever physiological problems. These problems might be amplified due to the stress of pregnancy.
