“…Increasing level of fibrolytic enzymes increased rate and production of in vitro gas with some raw agricultural waste 33 or total mixed rations of different roughage concentrate ratios. 34 Colombatto et al 4 reported short-term effect of enzymes on the degradation of feeds, with limited effects during fermentation. This continuous effect might be partly due to the pre-incubation effect that may form stable enzyme-feed complex.…”

The use of two probiotic products as a means of improving in vitro and ruminal dry matter digestibility, fermentation characteristics and growth performance of Barki lambs were evaluated. The probiotic products in powder (PP) or liquid (PL) forms were produced from Ruminococcus flavefaciens, through an anaerobic fermentation process. Barki lambs (n ¼ 30; 24.5 ± 0.5 kg body weight) were used in a completely randomized block design and randomly assigned among three experimental groups and fed for 75 days. Lambs were fed an equal amount of concentrate feed mixture with either no probiotic product (control), or with 20 g of PP, or 10 ml of PL per animal/d, with rice straw ad libitum. Both PP and PL treatments resulted in an increase (p < 0.05) in nearly all of the digestibility coefficients, nitrogen utilization, cell wall constituents, total volatile fatty acids, rumen volume, microbial nitrogen synthesis, gas production and average daily gain compared to the control group. Ruminal ammonia nitrogen, acetic acid and in vitro methane concentrations and protozoa count decreased (p < 0.03) in the treatment groups. Overall, the probiotic in a powder or liquid form increased in vitro dry matter digestibility, improved lambs daily gain and nutrient digestibility.

“…Ruminants are one of the major producers of CH4 (Elghandour et al, 2017;Hernández et al, 2017). Supplementation of microalgae with high-fat feed showed positive effects as possible candidates to reduce CH4 production in ruminants (Gomaa et al, 2018) due to lipids, especially poly unsaturated fatty acids (PUFA), that have antimicrobial effects on ruminal methanogens and protozoa (Ebeid et al, 2020).…”

Recently, microalgae, natural marine resources, have gained increasing interests as a feed for animals. Chlorella vulgaris microalgae are single-cell microorganisms that have been used to provide nutrition to humans and animals for centuries. In the present review, we unveil the composition and nutritive value of C. vulgaris microalgae as a feed for ruminants. Research has shown that inclusion of C. vulgaris microalgae in diets improved feed utilization, milk production and quality, growth performance, and meat quality in ruminants, as a result of improved diet nutritive value leading to improved feed utilization. Very low doses of C. vulgaris in feed enhance growth and lactational performance of ruminants. Additionally, C. vulgaris showed very promising results as an alternative to corn and soybean meal; however, it is an expensive protein feed. Therefore, the main constraint to use of C. vulgaris as a feedstuff is its high cost of production, making improvement of cultivation technology to reduce the production costs a critical issue in the near future.

“…For many years, organic acids such as lactic acid, fumaric acid, malic acid, and formic acid have been used to improve the efficiency of beneficial ruminal microorganisms and fermentation [7,8]. They are described as "Generally Recognized As Safe" and have been approved by the European Union for animal feeding [9].…”

The present study aimed to evaluate the sustainable utilization of date palm leaves (DPL) and rice straw (RS) as feed materials for ruminants using an in vitro wireless gas production (GP) technique. Date palm leaves and RS were individually ensiled with lactic or malic acids at 5 g/kg DM for 45 days. In a total mixed ration containing concentrate feed mixture, vegetable/fruits byproducts, untreated RS, and berseem hay (control ration), untreated RS was completely replaced with treated RS (ensiled without additives or with lactic or malic acids) whereas berseem hay was replaced with DPL (ensiled without additives or with lactic or malic acid) at 25, 50, 75, and 100% levels. Significant treatment × replacement level interactions were observed (P < 0.01) for most measured parameters of gas, methane (CH4) and carbon dioxide (CO2) productions, and degradability and volatile fatty acid (VFA) concentration. Replacing berseem hay with increasing levels of lactic or malic acid-treated DPL gradually decreased (P < 0.01) the asymptotic total gas and CH4 and CO2 productions, and malic acid-treated DPL decreased the rates of total gas, CH4 and CO2 productions, and the lag time of total GP. Moreover, lactic acid-treated DPL linearly increased (P < 0.05) the concentration of total VFA and acetate. Malic acid-treated DPL did not affect the measured ruminal fermentation parameters. Compared with the malate-treated DPL, lactate-treated DPL increased dry matter and neutral detergent fiber degradability, total VFA and acetate concentrations, and decreased CH4 production. In conclusion, replacing berseem hay with malic or lactic acids improved ruminal fermentation and decreased CH4 and CO2 productions, which can be considered as a sustainable strategy for cleaner ruminant production. Lactic acid treatment of DPL may result in better ruminal fermentation characteristics than the malic acid treatment of DPL. Graphical abstract
