“…The differences could be due to different forage contents included in the diet, physiological age and race (Patiño and Van, 2010); also, environmental and management factors could affect the animal response. On the other hand, it could also be attributed to the palatability of the diet, protein content and intake, elevated intake of DM, better digestibility of the diet, and nitrogen use (Obeidat et al, 2020).…”

Objective: To evaluate the productive behavior of Creole sheep in the tropics fed a whole food diet that includes soybean (FS, Glycine max) fodder at different phenological stages. Methodology: The treatments T1: control, T2: 30% (SF-56 d), T3: 30% (SF-68 d), T4: 30% (SF-85 d), T5: 30% (SF-110 d) were assigned randomly to 30 male Creole sheep (15.51±1.6 kg LW). The experiment lasted 56 d. The variables evaluated were: dry matter consumption (DMC), daily weight gain (DWG) and feed conversion (FC). The experimental design wascompletely randomized and the averages of the treatments were compared using the Tukey test. Results: Differences (p<0.05) were found in DMC, DWG and FC. The DMC was lower (p<0.05) in the control group. The DWG was higher in the animals that consumed soybean fodder compared to the control group (0.205 vs 0.121 kg d-1). The FC decreased (p<0.05) 51% in T3 (SF 68 d), with respect to the control group. Study Limitations: The nutrient contribution of soybean fodder is based on the phenological stage of the plant. Likewise, producers in the tropical region have scarce knowledge about how to incorporate it in the feeding of small ruminants. Conclusions: The inclusion of 30% of soybean fodder at 68 d of age in a whole food diet improves the productive performance of the lambs because it increases daily weight gain and decreases feed conversion.

“…This mixed grass can be classified as a low quality forage. According to Obeidat et al (2019), low quality forages are deficient in crude protein (less than 8% crude protein; CP), low in soluble sugars and starches, and are made up of natural pastures or crop residues. Supplementing the mixed grass with the National Feed Mills (NFM) Ruminant mix (CP 135 g/kg DM, Table I) have shown that the combination is more than capable of meeting the CP needs of these animals.…”

“…This is in agreement with Hossain et al (2003), Yagoub & Babiker (2008) and Sayed (2009) who reported that the level of energy significantly influenced daily feed intake of lambs, suggesting that nutrient digestibility increases with increased supplementation. Obeidat et al (2019) concluded thatlambs supplemented with crude protein (CP) will have greater feed intake and growth compared to the non-supplemented lambs grazing low-quality forages.Water intake was highest (p<0.05) among animals supplemented at 3 % (15.3 L) of their body weight (Table II). It is possible that as digestibility increases there is a greater demand for water to conduct metabolic processes.This study illustrated that aaverage daily gain (ADG) was highest (p<0.05) among ewes supplemented at 3 % (0.70 kg) of their body weight.…”

This experiment was undertaken to investigate the effect of different inclusion levels of a commercial concentrate on average daily gain, feed conversion efficiency, feed intake, final weight gained, feed cost/lb gain and the dressing percentage of weaned lambs. Twenty one, clinically healthy Barbados black belly weaned ewe (average weight 15 -19± 0.4 kg.) were used. They were randomly allocated to three treatments during a period of 70 days. Treatment (1): inclusion at 2% body weight, Treatment (2): Inclusion at 2.5% body weight and Treatment (3): Inclusion at 3% body weight. Water was provided ad libitum. Feed intake was highest (p<0.05) among lambs supplemented with concentrates at 3 % (5.85 kg) of their body weight. Average daily gain (ADG) was highest (p<0.05) among ewes supplemented at 3 % (0.70 kg) of their body weight. Feed conversion ratio (FCR) was significantly lower among animals supplemented at 2 % (7.52 kg) when compared to animals supplemented at 2.5 % (8.50 kg) and 3 % (8.28 kg) of their body weight respectively. Weight gain was significantly higher (p<0.05) among ewes supplemented at 3 % body weight in comparison to ewes supplemented at 2 % (14.4 kg) and 2.5 % (16.3 kg) respectively. Ewes supplemented at 3 % of their body had a lower (p<0.05) feed cost per pound of gain ($7.71) when compared to those supplemented at 2.5 % ($ 9.52). Dressing percentage was also lowest (p<0.05) among ewes supplemented at 3 % of their body weight (42.9 %) when compared to ewes supplemented at 2 % (46 %) and 2.5 % (45.7 %) respectively. It was concluded that a higher concentrate inclusion level could positively influence the performance parameters and cost/pound of gain in weaned lambs fed poor quality forages.

“…The productivity of Awassi lambs depends on feed. Whole grains, such as barley (BAR) and corn (CORN), are the main ingredients in lamb diets since the availability of good quality forage in Jordan is limited by the harsh environment [ 4 ]. The nutritive value of BAR and CORN is reflected mainly in energy content; protein is considered of secondary importance [ 5 ].…”

Background and Aim: Grains, such as barley (BAR) and corn (CORN), are major energy sources for small ruminants. This study aimed to assess the impact of feeding either BAR or CORN-based diets on growth performance and carcass characteristics. Materials and Methods: Awassi male lambs, average body weight of 20.4±0.49 kg, were chosen randomly. Lambs were acclimated for 10 days and assigned to one of two diets (1) BAR and (2) CORN. Feeding continued for 70 days with 60 days of data collection. Daily intake was recorded. Measurements of body weight were taken starting from day 1 then once per week throughout the study period. On day 40, six lambs were randomly chosen from each group and placed in metabolism cages to assess digestibility and N balance. Lambs were slaughtered on the last day of the study to evaluate carcass characteristics and meat quality. Results: Neutral and acid detergent fiber and ether extract intake were greater (p≤0.05) for lambs fed the BAR diets. Nitrogen loss in feces tended to be greater (p=0.09) for the CORN diet. Eye muscle depth (mm) tended to be greater (p=0.07) for the BAR diet. Nutrient digestibility, daily weight gain, carcass characteristics, and meat quality were not different (p≥0.1) between diets. Conclusion: The results herein demonstrate that feeding BAR grain improved nutrient intake efficiency and consistency and did not affect weight gain and carcass traits. BAR-based diets might be a useful alternative to CORN for feeding growing lambs.
