“…Although there was no improvement in the liking of flavour and aroma, tenderness, juiciness and overall acceptance, there was also no negative effects on these attributes. The results for the remaining attributes are consistent with the overall results obtained by Nawaz et al (1992) and Hopkins and Nicholson (1999) who observed the effect of ingesting un-dried non-saline-land saltbush on eating quality. However, Hopkins and Nicholson (1999) did show that the sheep fed non-saline-land saltbush produced meat with a higher odour strength only.…”

“…Furthermore, a comparison with lucerne may be inconclusive as lucerne alone has been shown to affect the sensory properties of sheepmeat (Park et al, 1972). Nawaz et al (1992) also examined the effect of feeding saltbush collected from non-saline land and/or sorgum (Sorghum bicolor) on eating quality and also found no differences between the treatment groups.…”

Forage halophytes such as saltbush (Atriplex spp.) are widely used to revegetate Australian saline land and can provide a medium-quality fodder source. An animal house experiment was conducted to investigate differences in the carcass and eating quality of sheep ingesting saltbush from saline land in combination with a barley supplement. Twenty-six merino hoggets (two groups of 13) were fed either a 60 : 40 dried saltbush (Atriplex nummularia): barley (S 1 B) ration or a 33 : 25 : 42 lupins : barley : oaten hay ration (C) for 10 weeks prior to commercial slaughter. After 10 weeks, all sheep were commercially slaughtered and a single loin (from 12th rib to chump) collected from each animal for taste-panel analysis. Carcass weight, total tissue depth over the 12th rib 110 mm from the midline (GR fat depth), ultimate pH and colour were determined and X-ray bone densitometry used to estimate the fat content of the carcass. Blood samples were taken to assess the hormonal response to ingesting these diets and fatty acid profiles of the subcutaneous and intramuscular fat were determined. Both groups grew at the same rate (62 g/day) and had similar hot carcass weights (P . 0.01) (17.2 6 0.3 kg for S 1 B and 17.9 6 0.3 kg for C). However, these live weights may not be high enough to be commercially viable such that saltbush and barley may only be suitable as a maintenance feed. The S 1 B-fed sheep had a significantly (P 5 0.055) lower fat and higher lean content (P , 0.05) than the C group. This is a positive finding as fat denudation is a significant cost to processors and farmers can produce sheep that are depositing less fat or more lean per unit of live-weight gain. The decreased fat and increased lean content were attributed to the higher protein : energy ratio available for production and lower circulating insulin and higher growth hormone of the S 1 B-fed sheep. The lower body-fat content and lower metabolisable energy and digestible organic matter intake did correlate with the sheep fed the S 1 B diet, having a significantly lower percentage of unsaturated fat and equal levels of saturated fat than the C treatment. Diet had no effect on the ultimate pH or colour of the meat. Treatment had no significant effect on any of the eating-quality attributes (P . 0.1). The drying of the saltbush, the shorter length of the experimental period and the low carcass fat content were believed to have contributed to this result. Further field experiments are needed to clarify the benefits to carcass and eating quality of ingesting saltbush.

“…Kraidees et al (1998) reported that Najdi lambs fed with diets containing Salicornia stems tended to gain weight faster than those fed diets containing RGH. It was assumed that the body weight gain improvement might be related to increased body water retention and accumulation of sodium (Nawaz et al 1994;Kraidees et al 1998;Masters et al 2005). The animals in this study were able to increase their feed intake to compensate for the lower organic matter content of the SGH compared with RGH.…”

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.

“…Consequently, they struggle to maintain weight when grazing saltbush without supplementation mainly because of its high salt content (Masters et al, 2005;Chadwick, 2009). Moreover, it was assumed that the insignificant body weight gain due to feeding saltbushes alone might be related to increased body water retention and accumulation of sodium (Nawaz et al, 1994;Masters et al, 2005).…”

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.
