“…Consequently, the utilization of OC as an alternative feed for black goats is economically advantageous. This finding aligns with the prior scientific literature that has explored the use of alternative feeds as a means to decrease the expenses associated with traditional animal diets [19][20][21].…”

“…This finding is in agreement with previous research, such as the study conducted by Awawdeh and Obeidat [8], which found no disparities in DM, CP, and ADF digestibility when Awassi lambs were fed diets containing OC. Additionally, Ismail and Obeidat [21] reported similar findings, observing no variations in DM, CP, and ADF digestibility when incorporating sun-dried olive leaves into the diets of Awassi lambs. However, contrasting results were obtained in another study, indicating reduced nutrient digestibility except for EE in diets containing 150 g/kg OC feed in comparison to the commercial diet [6].…”

This study investigated the dietary effect of incorporating different levels of olive cake (OC) on the metabolic responses, growth performance, and carcass characteristics of black goat male kids. Thirty kids (body weight = 17.3 ± 0.40 kg) were randomly distributed into one of three equally sized dietary groups: a control diet (CON), OC at 75 g/kg (OC75), and OC at 150 g/kg (OC150) of dietary dry matter (DM). The results revealed that the intake of DM, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) was similar (p ≥ 0.11) among the three treatment groups. However, the OC150 group had the greatest (p < 0.0001) ether extract (EE) intake compared to the OC75 and CON groups. The growth measurements were similar (p ≥ 0.13) among the three groups. Feed efficiency was not affected by the inclusion of OC. In contrast to the CON diet, the cost of gain was, however, reduced (p = 0.004) in the OC diets. All three treatment groups’ digestibility of DM, CP, and ADF was similar. However, when compared to the OC75 and CON groups, the digestibility of NDF was better (p < 0.05) in the OC150 group. The N intake did not differ among the three experimental groups. Nitrogen retained as g/d was higher (p = 0.04) in the OC150 and OC75 groups compared to the CON group, while retention as a percentage (g/100 g) was similar among the three groups. Except for intermuscular fat, total fat, leg fat depth, and tissue depth, the inclusion of OC did not result in any discernible treatment effects on the carcass and meat quality parameters. Only alanine aminotransferase enzyme activity was lower (p < 0.0001) in OC-treated groups compared to the CON group. In summary, incorporating OC at 75 g/kg and 150 g/kg levels into the diets of black goat kids had positive comparable effects on some parameters related to growth performance, carcass attributes, and meat quality. Importantly, utilizing olive cake led to cost savings in production and may serve as a viable alternative feed source in goat nutrition.

“…The results of rice impurities replacement on gain (Table 4) showed an increase (P < 0.05) in the daily gain (g/day) and total weight gain (Kg), for replacement treatments and T3 (100%RI) was superior to others, the results indicated the possibility of replacing rice impurities instead of barley grains or wheat bran with a profitable production efficiency and avoid using expensive ingredients. The superiority of the T3 treatment in the daily and total gain, is due to high benefit of the feed to achieve synchronization between the amount, time and speed of degradation and fermentation of carbohydrates with the amount, time and speed of degradation and fermentation of protein in the rumen, that leads to increase numbers and activity of rumen microorganisms, and increase the digestibility of feed and feed efficiency [18], our results agreed with [22] who indicated to a significant superiority (P < 0.05) in the daily and total gain when replacing three levels of potato byproducts 0, 25, 50% instead of corn to achieve cheap feeds, and agreed with Mahmoud (2017) ) [20] who found no differences when replacing three levels of bakery residues (0, 30, 60%) instead of corn and wheat bran and produced low cost feeds. The goal of the substitution may be to improve nutritional value of feeds or recycling the by-products and reducing pollution to achieve environment sustainability, as replacing barley grains with bakeries residues [23], or the substitution for reducing the cost of feeds, or may combine all of the above, as replacing wheat bran with corn impurities [24].…”

“…Non-significant effect, in the digestibility of crude fiber, ether extract and crude protein, indicates the preference of using rice impurities and good or suitable rumen environments to digest feed. The results agreed with others who substituted by-products with feed an expensive feed ingredient, [20] improved digestibility when replacing corn and wheat bran with bakeries residues, and [21] found no differences in the digestibility when replacing dried olive leaves with soybean meal for Awassi sheep. column means significant differences; NS= non-significant differences; ** Significant differences at level 0.01.…”

This experiment was conducted to evaluate the effect of substitution three levels of rice impurities 0%, 50% and 100% instead of wheat bran or barley grains on digestibility and productive performance of Awassi lambs. In the morning, concentrated feed was given individually at 3% of live body weight as a dry matter basis for 56 days preceded by 14 days as an adaptation period. Roughage intake (wheat straw) was given ad-libitum (with residue) and recorded. Twenty-four male lambs aged 3-4 months with an initial weight 24.66 ± 2.81kg divided into six treatments with replacing rice impurities 0%, 50% and 100% instead of wheat bran (T1), T2, T3) or barley grains (T4, T5, T6) in a 2×3 factorial experiment/Completely Randomized Design. The results showed no significant differences in daily intake of dry matter (DM), organic matter (OM), crude protein (CP), soluble carbohydrates (NFE) and metabolizable energy (Me), and an increase (P < 0.05) in the intake of ether extract (EE), crude fiber (CF) (P < 0.01) and ash in T6 (100% rice impurities instead of barley), while daily gain and total gain increased significantly (P<0.05) for treatment T3 (100% rice impurities instead of wheat bran) 198.21g/day and 11.1kg in contrasted to others. feed efficiency and digestibility didn’t differ when replacing rice impurities. In conclusion: It’s possible to use rice impurities instead of barley grain or wheat bran to achieve low-priced feed ingredients with a higher weight gain and sustainable development.

“…As conventional imported feed ingredients may negate profit margins for sheep, livestock producers have begun to search for alternative feeds at lower costs [3]. This research program conducted a series of experiments and found that the use of alternative feeds decreases the cost of production without impacting the health status of small ruminants [2][3][4][5][6]. Feeding by-products from local sources, such as pomegranate seed pulp (PSP) and coconut meal (COC), to livestock can reduce the cost of milk production and increase profits.…”

Background and Aim: Feeding by-products, such as pomegranate seed pulp (PSP) and coconut meal (COC), to livestock may enhance production efficiency and increase profits. This study aimed to evaluate the effects of PSP and COC on milk production, body weight change, metabolic response (Exp. 1), digestibility, and N balance (Exp. 2). Materials and Methods: Twenty-four ewes nursing single lambs were randomly assigned to one of three diets: Control (CON) (n = 8), 7.5% PSP (n = 8), and 7.5% COC (n = 8) of dry matter (DM). Every sheep was born 3–4 days before the start of the experiment. The 1st week of the experiment was devoted to diet adaptation, while the data were collected during the following 8 weeks (Exp. 1). Nine lambs were randomly assigned to one of the three diets for intensive data collection to evaluate the diet digestibility and animal nitrogen (N) balance (Exp. 2). The data were analyzed using the MIXED SAS procedures. Results: The PSP group consumed more DM, followed by the COC and CON groups. For lambs, the final BW, total gain, and average daily gain in the PSP group were greater (p < 0.05) than those in the COC and CON groups. The CON group had lower milk output, total solids, protein, fat, and lactose levels than the PSP and COC groups (p < 0.05). The cost of milk production was lower (p < 0.05) in the PSP and COC diet groups than in the CON group. Blood serum parameters were similar among the dietary groups, except for total cholesterol and high-density lipoprotein, which were higher in the COC group than in the CON group. No differences were observed in nutrient digestibility and N balance. Conclusion: Feeding PSP and COC to nursing ewes appears beneficial because it increases milk production and pre-weaning lamb growth and reduces milk production cost. Keywords: Awassi ewes, coconut meal, milk yield and quality, pomegranate seed pulp.
