“…As previously noted, increased ruminal propionate with the additives could elevate precursor's availability for glucose and lactose synthesis (Linn, 1988). Kholif et al (2020b) observed similar results with feeding the same additives mixture without chelated minerals to lactating cows. However, Lakhani et al (2019) observed that supplementing diets of growing buffalo calves with a mixture of neem seed cake, mahua seed cake, fennel seed, harad, fruit pulp of bahera, fruit pulp of amla, and ajwain seed mixed in 2:2:2:1:1:1:1 proportion decreased serum glucose.…”

“…Cows were fed a control diet (PHY0 treatment) containing [per kg dry matter (DM)] 500 g of concentrate feed mixture, 300 g of corn silage (Zea mays) and 200 g of rice straw (Oryza sativa) to meet their nutrient requirements according to NRC (2001) recommendations for first 3 months of lactation. In the other experimental diets, cows were supplemented with chelated additives mixture at 3 g (PHY3 treatment) or 6 g (PHY6 treatment)/cow daily based on the recent recommendations (Kholif et al, 2020b). Adjustments were made to the amount of diets offered to ensure collection of leftover (requirements + 10% margins).…”

The present experiment evaluated the inclusion of chelated phytogenic feed additives mixture in the diet of lactating cows for the first 3 months of lactation. A week before calving, thirty multiparous Friesian cows were divided into three treatments in a complete randomized design and fed a basal diet without supplementation (Control treatment), or the control diet supplemented with chelated phytogenic additives at 3 g (PHY3 treatment), or at 6 g/cow/d (PHY6 treatment). Menthol, levomenthol, β-linaloolm, anethole, hexadecanoic acid and pmenthane were the principal compounds identified in the additives mixture. Milk production, total solid, protein, fat, and lactose were increased with PHY3, but decreased by PHY6 (P<0.01). Whereas the PHY3 treatment increased (P<0.05) milk contents of Ca and Zn, PHY3 and PHY6 treatments increased (P<0.05) milk Fe and Mn concentrations. Though the PHY3 treatment increased (P<0.05) nutrient digestibility, the PHY6 treatment decreased (P<0.05) the digestibility of organic matter, crude protein and neutral detergent fiber. The PHY3 treatment increased (P<0.05) ruminal volatile fatty acids (VFA) concentration and proportional acetate and propionate and decreased butyrate, while the PHY6 treatment decreased ruminal VFA concentration and proportional acetate. The PHY3 treatment increased (P<0.05) serum total protein, glucose, total antioxidant capacity, and the concentrations of Ca and Zn. Both PHY3 and PHY6 treatment decreased (P<0.05) the concentrations of serum triglycerides, and cholesterol. Daily inclusion of 3 g/cow of chelated feed additives mixture in diet of lactating cows improved milk production and ruminal fermentation, but additives dose of 6 g/cow/d had negative impact on cows’ performance.

“…Moreover, we need to explore natural feed additives with limited or no adverse effects to manipulate rumen fermentation to improve feed digestibility and utilization. Plant secondary metabolites are natural substances with the potential ability to alter rumen fermentation without causing microbial resistance, and their residual effects can positively affect the animal end products (27,28). Owing to the excellent antimicrobial activities of phytochemicals, they are considered as a potential modulator of the rumen microbiome to alter rumen physiology (29).…”

Phytogenic Additives Can Modulate Rumen Microbiome to Mediate Fermentation Kinetics and Methanogenesis Through Exploiting Diet–Microbe Interaction

Ruminants inhabit the consortia of gut microbes that play a critical functional role in their maintenance and nourishment by enabling them to use cellulosic and non-cellulosic feed material. These gut microbes perform major physiological activities, including digestion and metabolism of dietary components, to derive energy to meet major protein (65–85%) and energy (ca 80%) requirements of the host. Owing to their contribution to digestive physiology, rumen microbes are considered one of the crucial factors affecting feed conversion efficiency in ruminants. Any change in the rumen microbiome has an imperative effect on animal physiology. Ruminal microbes are fundamentally anaerobic and produce various compounds during rumen fermentation, which are directly used by the host or other microbes. Methane (CH 4 ) is produced by methanogens through utilizing metabolic hydrogen during rumen fermentation. Maximizing the flow of metabolic hydrogen in the rumen away from CH 4 and toward volatile fatty acids (VFA) would increase the efficiency of ruminant production and decrease its environmental impact. Understanding of microbial diversity and rumen dynamics is not only crucial for the optimization of host efficiency but also required to mediate emission of greenhouse gases (GHGs) from ruminants. There are various strategies to modulate the rumen microbiome, mainly including dietary interventions and the use of different feed additives. Phytogenic feed additives, mainly plant secondary compounds, have been shown to modulate rumen microflora and change rumen fermentation dynamics leading to enhanced animal performance. Many in vitro and in vivo studies aimed to evaluate the use of plant secondary metabolites in ruminants have been conducted using different plants or their extract or essential oils. This review specifically aims to provide insights into dietary interactions of rumen microbes and their subsequent consequences on rumen fermentation. Moreover, a comprehensive overview of the modulation of rumen microbiome by using phytogenic compounds (essential oils, saponins, and tannins) for manipulating rumen dynamics to mediate CH 4 emanation from livestock is presented. We have also discussed the pros and cons of each strategy along with future prospective of dietary modulation of rumen microbiome to improve the performance of ruminants while decreasing GHG emissions.

“…The major finding of the current study was that ensiling of olive cake without or with fibrolytic enzymes increased production of daily milk (by 17.5 and 17.8%, respectively) and ECM (by 18.2 and 27.1%, respectively). This reflects the cumulative effect of improved nutrient digestion and altered ruminal fermentation (Kholif et al, 2021) with feeding olive cake (Chiofalo et al, 2004). Increasing milk production without affecting feed intake was reflected as enhanced feed (milk) efficiency calculated as milk yield/DM intake by 10.8, 16.2 and 16.2%…”

The present experiment aimed to evaluate the inclusion of dried olive cake treated or untreated with fibrolytic enzyme, partially replacing concentrates in the diet of ewes. Forty lactating Barki ewes, weighing 37.1 ± 4.0 kg, were assigned into four treatments (n=10) in a complete randomized design for 9 weeks. Ewes were stratified according to parity (2 ± 1 parity) and previous milk production (615 ± 11 g/d). The control diet consisted of concentrates and fodder maize at 60:40, respectively. For the experimental diets, 30% of the concentrates was replaced with dried olive cake (DOC treatment), olive cake silage (SOC treatment) or olive cake silage treated with fibrolytic enzymes (ESOC treatment). Without affecting intake, DOC, SOC and ESOC diets enhanced (P<0.05) dry matter, organic matter and non-structural carbohydrate digestibility; however, ESOC diets increased (P<0.05) neutral detergent fiber and acid detergent fiber digestibility. Additionally, DOC, SOC and ESOC diets increased (P<0.05) ruminal total volatile fatty acids, acetate and propionate without affecting ruminal pH and ammonia-N concentration. The ESOC diet increased serum glucose concentration (P=0.019). Both of SOC and ESOC diets increased (P<0.05) daily milk production and energy corrected milk as well as milk fat concentration (P=0.028). All of DOC, SOC and ESOC increased (P<0.05) feed (milk) efficiency compared with the control diet. It is concluded that 30% of concentrates can be replaced with olive cake without negative effects on performance but with better performance when olive cake was ensiled with or with or without fibrolytic enzymes.
