“…Wheat straw is commonly used as a foraging source in small ruminant diets; however, it contains high levels of fibre and low levels of protein, which result in lower digestibility and productivity (Obeidat et al 2014). Obeidat (2017) suggested that olive cake (OC)the agro-industrial byproduct of olive oil extractionand Atriplex halimus L. (ATR)a Mediterranean saltbushare suitable alternative foraging sources to wheat straw (Obeidat et al 2016).…”

The objective of the two studies was to evaluate t effects of feeding on lactating Awassi ewes (study 1) and lambs (study 2), fed on a diet of Atriplex halimus L. (ATR) or olive cake (OC), as a foraging source substitute for wheat straw. In study 1, 33 newly lambed ewes and their lambs were randomly assigned one of three diets: The control diet (CON), 250 g/kg of OC, or 250 g/kg of ATR dry matter (DM). Ewes and lambs were housed in individual pens. Ewes fed CON diet had greater DM, neutral detergent fibre, and acid detergent fibre intakes than OC and ATR groups. Ether extract (EE) intake was greater (p < .0001) in OC diet compared to CON and ATR diets. Milk yield was similar (p ¼ .99) among treatments. Content of milk total solids and fat were greater in ATR diet than CON and OC diets. Milk production cost was lower in the OC and ATR compared to the CON group. In study 2, 18 ewe lambs were assigned the same diets used in study 1 to evaluate the effects of OC and ATR on nutrient digestibility and N balance. Dry matter digestibility was greater in ATR compared to CON and OC groups. The digestibility of EE was greater in the OC group than in CON and ATR groups. Results showed that the inclusion of OC and ATR did not negatively impact lactation performance. Additionally, results proved the economic value of using such products, as they reduced the cost of milk production. HIGHLIGHTS Olive cake and Atriplex halimus L. were fed to Awassi ewes at a level of 250 g/kg of dietary DM. The inclusion of olive cake and A. halimus L. at 250 g/kg of dietary DM, as a source of fibre, did not negatively impact the lactation performance of sheep. Additionally, results proved the economic value of using such products, as they reduced the cost of milk production.

“…In Middle Eastern countries like Jordan, pastures are a primary source of nutrients for small ruminant producers. However, because available pastures are insufficient and often inferior in quality (Obeidat et al 2014), animals are supplemented with grains and other concentrates to enable them to meet their nutrient requirements, especially during the high-producing phase, such as milk production. The early stages of milk production are critical as they affect the lactation outcome and, hence, lamb preweaning growth.…”

The effect of corn dried distillers grains with solubles (DDGS) on milk yield, milk composition and body weight (BW) and digestibility were evaluated by using lactating ewe (Exp. 1) and Awassi ewe lambs (Exp. 2). Dietary treatments were (1) no DDGS (CON), (2) 200 gkg À1 DDGS (DDGS200) or (3) 300 gkg À1 DDGS (DDGS300) of dietary dry matter (DM). In Exp. 1, 30 lactating Awassi ewes were randomly assigned to the corresponding diets. Nutrient intakes were determined daily throughout the experiment which lasted for 8 weeks. Body weights of ewes and lambs were measured on days 0, 28 and 56 of the study whilst milk yield and composition were recorded on days 18, 36 and 54. Ewe BW changes were similar amongst treatments. Ewes consuming the DDGS diet showed increased milk production (p<.045) over those provided the CON diet. Cost of diets and milk production reduced (p¼.01) in DDGS-containing diets compared with the CON diet. In Exp. 2, 18 Awassi ewe lambs were randomly assigned into the same dietary treatments and fed their diets for 21 days. Digestibility of DM and ADF was lower (p<.017) for the CON diet than for the DDGS diets. Digestibility of CP and NDF increased (p<.036) in the DDGS200 diet than the CON diet. Results indicate DDGS has the potential to be included up to 300 gkg À1 of dietary DM of DDGS in Awassi ewes' diets with no negative effects on production parameters whilst being cost effective. HIGHLIGHTS Cost of feed and milk production decreased in DDGS diets. Milk production increased in DDGS diets. Milk composition was similar among diets.

“…These animals are the primary livelihood of Jordanian farmers living in rural and marginal regions, as they contribute to food security and risk assurance [ 2 ]. Despite adaptive traits that enable these animals to thrive in arid and semi-arid environments, small ruminant livestock productivity is often limited by various factors, such as feed and water shortages, diseases, and rangeland reductions [ 3 ]. The increased temperatures and declining amounts of precipitation associated with climate change in Jordan have amplified these limiting factors (especially water shortages) [ 4 ].…”

Assessment of water source availability and quality for small ruminant consumption in the Northern Badia region of Jordan

et al. 2020

Background and Aim: Water is the most important nutrient for the production of healthy livestock. Water scarcity bottlenecks livestock production in arid and semi-arid regions, particularly during the dry season. This study aimed to assess water availability and quality for small ruminants, and to identify major challenges of meeting their water requirements in two major small ruminant production systems in Jordan. Materials and Methods: Transhumant and sedentary production systems in the Northern Badia region of Jordan were the focus of this study. A questionnaire was distributed to 120 sheep and goat farmers (62 transhumant farmers and 58 sedentary farmers) and a water quality assessment was completed. Results: Results showed that the two production systems varied their water source use seasonally. Water provision was perceived as one of the major constraints for Bedouins, particularly during the dry season in transhumant production systems, when longer distances to water sources and the high costs of fetching water daily aggravated the problem. The mean distance and travel times to the boreholes were less in the sedentary system. Watering frequency was significantly lower in the transhumant system compared to the sedentary system (p<0.05). Although the values of water quality parameters complied with guidelines for livestock consumption, low water quality was the main concern expressed by some of the survey households. Conclusion: Technical support to properly design, manage, and rehabilitate surface water harvesting systems is required for the sustainable use of water resources in the study region. Moreover, systematic water quality monitoring is necessary to ensure its suitability for livestock use. Further investigations on the microbiological quality of water and its effect on the health and performance of livestock are recommended.
