An experiment was conducted to see how replacing soybean meal with chickpea grains (CHPE) affected the performance, milk production, digestibility, nitrogen (N) balance, and blood metabolites of Awassi ewes. Thirty Awassi ewes with an initial body weight of 53.2 ± 2.31 kg and aged between 4 and 5 years were selected and randomly assigned to different feeding treatments (10 ewes per diet). Dietary dry matter (DM) was (1) 0 g/kg CHPE (CON); (2) 150 g/kg CHPE (CHPE150); and (3) 300 g/kg CHPE (CHPE300). The costs of these diets were determined using current ingredient prices. The experiment lasted 9 weeks. During the trial, ewes and their lambs were kept in individual pens. Daily nutrient intake was monitored. Every 2 weeks, the body weight (BW), milk output, and composition of the ewes were measured. In comparison to the CON diet, adding the CHPE to the experimental diets lowered feed costs (US$) per ton by 11% for CHPE150 and 21% for CHPE300. The CHPE300 group had a lower (P < 0.05) consumption of neutral detergent fiber (NDF) than the CHPE150 group, while the CON group had the highest (P < 0.05) intake of NDF. The intake of ether extract (EE) (g/d) was higher (P < 0.05) in the ewes fed the CHPE300 compared to the ewes fed CHPE150, and it was lowest in ewes fed the CON diet. When the ewes were fed the CHPE300 and the CHPE150 diets, the total solids (g/kg) in each kg of milk produced per day was higher (P < 0.05) than when they were fed the CON diet. The cost per kg of milk produced by the ewes was lowered (P < 0.05) when the CHPE was added to their diets. When the ewes on the CHPE300 and the CHPE150 diets were compared to the ewes on the CON diet, crude protein (CP) digestibility was higher (P < 0.05). The EE digestibility was higher (P < 0.05) for the CHPE300 group, while the CHPE150 group had an intermediate outcome. The CHPE300 group had lower amounts of N in their feces and urine (P < 0.05) than the other groups. The retention of N (g/100 g) in the ewes fed the CHPE300, and the CHPE150 diets was higher (P < 0.05) than in the ewes fed the CON diet. As a result, the current research demonstrates that part of soybean meal and barley grain could be replaced with chickpeas in the diets of lactating Awassi ewes.
This study was conducted to evaluate the effects of substituting wheat straw with corn stover (CS) on the growth performance and blood parameters of lambs fed on a concentrate diet. Male lambs were split into two groups, with 16 lambs in each. Following a 7-days adaptation period, one group received a diet containing 0 g/kg CS (CS0) and the other group received 100 g/kg CS (CS100) for 56 days. The following growth-related parameters were evaluated: feed intake, digestibility, N balance, total weight gain, average daily gain and blood parameters. The production cost was also assessed. Dry matter (DM) and crude protein (CP) intake increased (p .05) for lambs fed the CS100 diet. Lambs introduced to the CS100 diet were better able to digest (p .05) DM, CP, neutral detergent fibre, and acid detergent fibre. N intake and retention improved, while N lost in faeces tended to increase (p .08) in lambs fed the CS100 diet. Average daily weight gain was greater (p ¼ .03), and cost of gain was lower (p ¼ .001) for lambs fed the CS100 diet. Blood glucose increased while creatinine was reduced (p < .05) for lambs fed the CS100 diet. These results indicate that feeding lambs the CS100 diet is efficient and would increase profitability. In conclusion, feeding corn stover had a positive impact on growth rate, reduced production costs, and had no negative effect on health. Therefore, we recommend that lambs should be fed diets that include CS100
Blood metabolites and growing performing were evaluated in lambs (15.7±0.33 kg; initial body weight) fed diets containing either soybean meal or cold extraction sesame meal (SM). The design of the study was a complete randomized design. Twenty-two lambs were divided into two diets, 0% SM (CON) or 12.5% SM (SM12.5) of dietary dry matter (DM), raised for 84 days (7 and 77 days for adaptation and data collection, respectively) and fed ad libitum diets (crude protein (CP) content 15.6% DM). Parameters that were measured included nutrient intake, average daily gain (ADG), digestibility, N balance, and blood parameters. Excluding ether extract (EE) and metabolizable energy intake which were greater (P≤0.05) in the SM12.5 group versus the CON group, no diferences in other nutrient intakes were detected (P≥0.05) between the two diets. Lambs fed the SM12.5 diet had more digestibility for DM, CP, neutral detergent fber, and EE. Nitrogen in feces was lower (P≤0.05) in the SM12.5 group versus the CON group. However, retained N (g/day) increased (P≤0.05) in the SM12.5 group versus the CON group. Final body weight and ADG improved (P≤0.05) in the SM12.5 diet. Cost per kilogram of gain diminished (P≤0.05) in the SM12.5 than the CON diet. Blood glucose increased while creatinine decreased (P≤0.05) in lambs that consumed SM12.5. Results obtained herein proved that replacing soybean meal with sesame meal improved growth performance while reducing the cost of gain in addition to not afecting health negatively.
This study aimed to evaluate the effect of feeding growing Awassi lambs on sweet lupin (LUP; Lupinus angustifolius) on nutrient intake, in vivo digestibility, growth performance and carcass quality. Twenty-seven lambs (average body weight (BW) 16.5 ± 0.88 kg) were assigned randomly to 3-diet groups, namely:1) no LUP (CON), 2) 125 g/kg LUP (LUP125) or 250 g/kg (LUP250) dry matter (DM) in replacement of portion of barley grain and soybean meal. The study lasted for 84 days (first 7 days were used as adaptation period followed by 77 days to collect the data). Nutrient intake was measured daily. Lambs’ BW was measured at the commencement of the study and every two weeks during the whole study. On day 60, 15 lambs (5 from each group) were chosen at random and moved to metabolism cages to determine nutrient in vivo digestibility and N balance parameters. Lambs fed LUP250 showed greater (P ≤ 0.05) intakes of DM, crude protein and ether extract than the CON and LUP125 fed groups; however, their NDF data tended (P = 0.07) to surpass other groups. Intake of metabolizable energy was greater (P = 0.02) in lupin-containing diets than the CON diet. Lambs’ fed LUP250 diet had greater (P < 0.05) total gain and average daily gain than the CON diet. In vivo digestibilities, N retention, carcass characteristics of longissimus muscle linear dimensions and cooking loss was not affected by treatment. The CON-fed lambs had the highest (P < 0.001) water holding capacity followed by the LUP250 and LUP125 groups. The whiteness (L*) and yellowness (b*) were lower (P ≤ 0.05) for the LUP125 diet than the CON and LUP250 diets. From the study, it can be concluded that the inclusion of sweet lupin at 250 g/kg DM improved the growing performance without affecting carcass characteristics of lambs.
This study was designed to investigate how dairy farmers of Al-Dhulel Cooperative Dairy Society (ACDS) perceive climate change, the adaptation strategies adopted by farmers to cope with the impact of climate change and the barriers to the adoption of these strategies. A 92 dairy farmers responded to a designed questionnaire that was developed to collect the data and covered farmers perception, adaptation strategies, and the barriers facing them towards adopting the strategies. The personal interviews with the farmers were performed during early January, 2020. The data was analyzed using the Statistical Package for Social Sciences (SPSS). The main result obtained from the study that most of dairy farmers were aware of the climate change impact on dairy cattle performance and health. Furthermore, the adaptation strategies that were suggested have limiting factors according to farmers as a result of governmental and agricultural institutions restriction polices. Therefore, recommendations regarding new polices were suggested to facilitate the way of getting benefit from grants and financial support for improving dairy farms and to mitigate the effect of climate change on dairy cattle
An experiment was conducted to indicate the effect of feeding high energy diet for 45 days on male and female Awassi lambs’ performance, carcass percentage, and cost of production. A total of twenty four Awassi lambs (12 males, and 12 females) averaging 18.2±0.70 kg body weight were used. Lambs were assigned randomly to two different groups (groups A and B); each group had twelve lambs (6 males and 6 females) and fed two different diets (low energy diet and high energy diet). Feed intake, total gain, average daily gain and feed conversion ratio was calculated and body measurements (height and length) were recorded. Lambs were slaughtered at the end of experiment, to evaluate carcass percentage. Cost of production was calculated based on ingredients’ price at the time of the experiment. Final body weight, weight gain, and average daily gain were greater (p < 0.05); while feed conversion ratio was lower (p < 0.05) for lambs fed high energy diet than lambs fed low energy diet. Body length differences measured to be greater (p < 0.05) for male lambs fed high energy diet than other lambs. Fasted weight, hot carcass weight, and dressing percentage were higher (p < 0.05) for lambs fed the high energy diet. Cost of gain was lower (p < 0.05) for lambs in group B compared to lambs in group A. Therefore, the economical efficiency in this experiment was greater for lambs fed high energy diet than lambs fed the control diet during 45 days fattening period
Aim The aim of this study was to evaluate the effect of feeding low (LO)- or high (HI)-fiber diets supplemented with Saccharomyces cerevisiae (SC) on nutrient intake, digestibility, nitrogen balance, rumen fluid pH, and serum concentrations of glucose and urea nitrogen in Awassi female lambs in a 2×2 factorial arrangement of treatments. Materials and Methods Experimental diets were as follows: (1) LO-fiber diet with no SC supplementation (−LO), (2) LO-fiber diet supplemented with SC (+LO), (3) HI-fiber diet with no SC supplementation (−HI), or (4) HI-fiber diet supplemented with SC (+HI). Eight female lambs were used in a replicated 4×4 Latin square design with 15-day experimental periods (10-day adaptation period and 5-day collection period). Results A fiber×SC interaction (p≤0.05) was detected for dry matter (DM) and crude protein (CP) intake among diets showing greater DM and CP intake for +LO diet compared to +HI group supplemented with SC, whereas −LO and −HI were intermediate. A fiber×SC interaction (p=0.05) was also detected for the neutral detergent fiber (NDF) intake among diets. Intake of NDF was greater for the –HI diet compared with +LO and –LO diets. Similarly, NDF intake was greater for +HI diet than –LO diet. A tendency (p=0.07) for a fiber×SC interaction was detected for acid detergent fiber (ADF) intake among diets as well. ADF intake tended to be greater for HI-fiber diets. No difference was observed in the rumen fluid pH for lambs fed with the different diets. No fiber×SC interactions were detected for the digestibility of DM, CP, NDF, and ADF among dietary treatments. Digestibility of DM was greater (72.9 g/100 g vs. 67.1 g/100 g; p=0.0002) for LO versus HI fiber. However, NDF and ADF digestibilities were greater (60.8 and 61.9 g/100 g vs. 55.8 and 52.7 g/100 g for NDF and ADF digestibility, respectively; p≤0.01) for the HI-fiber than the LO-fiber diets. Conclusion Results obtained in the current study indicate that SC supplementation has a minimal effect on the performance of Awassi female lambs fed with varying fiber levels.
Two experiments were conducted to assess the influence of sesame meal (SM) feeding on nutrient digestibility, N balance, milk production and composition, ewes’ body weight change, and growth performance of lambs. In experiment 1, 18 ewe lambs were randomly distributed into three diets to evaluate the effects of soybean meal replacement with SM on nutrient intake, digestibility, and N balance. Treatments were no SM (SM0), 7.5% SM (SM7.5), or 15% SM (SM15) of the dietary dry matter (DM). Aside from intake and digestibility of ether extract (EE), which was greater in the SM-containing diets compared with SM0, intake and digestibility of the remaining nutrients was similar among dietary treatments. In experiment 2, 30 ewes suckling single lambs were randomly assigned to the same diets used in experiment 1. Intakes of DM, crude protein, neutral detergent fiber, and acid detergent fiber were unaffected by treatment. Milk yield was greater in SM diets than in the SM0 diet. Cost/kg of milk production decreased while feed efficiency improved in the SM-diets compared to the SM0 diet. In conclusion, results of the current studies demonstrate the possibility of replacing soybean meal with sesame meal in diets of lactating Awassi ewes.
Carcass parameters and meat quality in lambs that consumed diets having layer hen litter (LL) were evaluated in a complete randomized study. Forty-two lambs were allocated equally (14 lambs/treatment diet) into one of three iso-nitrogenous diets for 75 days. To partially replace soybean meal and barley, LL was given at 0 (LL0), 150 (LL150), or 300 g/kg (LL300) of dietary dry matter (DM). At the termination of the trial, the characteristics of carcasses (hot and cold carcass weight, dressing percentage, and carcass cuts) and meat quality (Musculus longissimus linear dimensions, ultimate pH, cooking loss, water holding capacity (WHC), shear force (SF), color coordinates) were measured after slaughtering all lambs. Longissimus muscle weight was greatest (p < 0.05) for the LL150. For the dissected loin, intermuscular fat content was lowest for the LL0 diet. However, subcutaneous fat content was lower (p < 0.05) in the LL300 diet than LL0 and LL150 diets. Rib fat depth and Musculus longissimus area were greater (p < 0.05) for LL150 than L0. No differences were found in meat pH or color parameters among treatments but WHC and SF were lower in L0 lambs than in lambs fed LL containing diets. Cooking loss was greater for the LL300 diet than the LL0 diet. In summary, quality of meat and carcasses data indicate the possibility of inclusion of LL up to 300 g/kg DM to growing Awassi lambs.
The objective was to investigate the effect of supplementing Awassi lambs fed low-quality forage with soybean meal. Twenty-one lambs (initial body weight (BW) of 26.1 ± 2.57 kg) were randomly assigned to the study diets, 1) the basal diet (forage mix; CON; n = 7); 2) the basal diet supplemented with either 125 (SBM125; n = 7); or 3) with 250 (SBM250; n = 7) SBM g/head/day. The forage mix was composed of 65% wheat straw and 35% alfalfa hay. The experimental diet was offered to the animals for 54 days. On day 40, four animals from each group were chosen to assess N balance and nutrient digestibility. The intake of crude protein (CP) and dry matter (DM) was the highest (p < 0.016) in the SBM250 group, followed by the SBM125 group and the CON diet. Digestibility of DM and CP was higher (p <0.05) for the SBM-containing diets than the CON diet. Final BW and average daily gain were greater (p < 0.008) for lambs that consumed SBM-containing diets than for those that consumed the CON diet. In summary, the growth performance, forage utilization, and nutrient digestibility improved for lambs fed low-quality forage when supplemented with soybean meal.
