“…On the other hand, GABA may exert a crucial effect on ameliorating fermentation environment of rumen microorganisms. Previous study has demonstrated that GABA‐producing bacteria or RP‐GABA can ameliorate rumen pH value and increase antioxidant activity, and facilitate rumen microbial fermentation (Ku et al, 2013). Presumably, the stimulation of the activity of ruminal fiber‐degrading bacteria by CHM and the amelioration of the fermentation environment of rumen microorganisms by RP‐GABA exert a synergistic effect to promote NDF absorption.…”

The high temperature and humid weathers coupled with low wind speed can induce heat stress in animal, resulting in reduced growth performance, compromised health status, or even death (Mader, Davis, & Brown-Brandl, 2006). Heat stress is known to disturb metabolic and physiological processes required for optimal cattle productivity, as well as cattle immunity (Collier, Collier, Rhoads, & Baumgard, 2008; Rhoads et al., 2009; West, 2003). Previous studies demonstrated that heat stress lowers average daily feed intake (ADFI) and average daily gain (ADG), which significantly increases breeding cost and compromises production profit (Piotr, Sabina, & Jacek, 2018; Polsky & Von Keyserlingk, 2017). Therefore, it is necessary to develop anti-heat stress therapy to improve the cattle production efficiency. Natural products, such as traditional Chinese herbal medicine (CHM) and γ-aminobutyric acid (GABA), have received remarkable attention due to their anti-heat stress potential (Song, Xu, Wang, &

“…In presence of feline faecal inocula, group CT failed to decrease the amount of biogenic amines, even though group YSE reduced cadaverine but increased spermine concentration. Ammonia and biogenic amines are also products which derive from proteolytic reactions; in particular, biogenic amines are generally formed through the decarboxylation of specific free amino acids by microbial decarboxylases (Ku et al 2013). The inhibitory effects of tannins on microbial proteolysis had already been observed by Biagi et al (2010) in piglets (both in vitro and in vivo), and by Hassanat and Benchaar (2013) in presence of ruminal inoculum.…”

The in vitro effect of a Yucca schidigera extract (YSE) and tannins from chestnut wood on composition and metabolic activity of canine and feline faecal microbiota was evaluated. Four treatments were carried out: control diet, chestnut tannins (CT), YSE and CT + YSE. The YSE was added to canine and feline faecal cultures at 0.1 g/l, while CT were added at 0.3 g/l for a 24-h incubation. A total of 130 volatile compounds were detected by means of headspace-solid phase microextraction gas-chromatography/mass spectrometry analyses. Several changes in the metabolite profiles of fermentation fluids were found, including a decrease of alcohols (-19%) and esters (-42%) in feline and canine inoculum, respectively, which was due to the antibacterial properties of tannins. In canine inoculum, after 6 h, YSE + CT caused lower cadaverine concentrations (-37%), while ammonia (-4%) and quinolone (-27%) were reduced by addition of CT. After 24 h, the presence of CT resulted in a decrease of sulphur compounds, such as dimethyl sulphide (-69%) and dimethyl disulphide (-20%). In feline faecal cultures, after 6 h, CT lowered the amount of indole (-48%), whereas YSE tended to decrease trimethylamine levels (-16%). Both in canine and feline inoculum, addition of CT and, to a minor extent, YSE affected volatile fatty acids patterns. In canine faecal cultures, CT exerted a marginal inhibitory effect on Escherichia coli population (-0.45 log 10 numbers of DNA copies/ml), while enterococci were increased (+2.06 log 10 numbers of DNA copies/ml) by YSE. The results from the present study show that YSE and tannins from chestnut wood exert different effects on the composition and metabolism of canine and feline faecal microbiota. In particular, the supplementation of YSE and tannins to diets for dogs and cats may be beneficial due to the reduction of the presence of some potentially toxic volatile metabolites in the animals' intestine.

Objective: The present study aimed to evaluate the effects of γ-aminobutyric acid (GABA)- producing bacteria (GPB) on in vitro rumen fermentation and on the growth performance and meat quality of Hanwoo steers.Methods: The effects of GPB (Lactobacillus brevis YM 3-30)-produced and commercially available GABA were investigated using in vitro rumen fermentation. Using soybean meal as a substrate, either GPB-produced or commercially available GABA were added to the in vitro rumen fermentation bottles, as follows: control, no additive; T1, 2 g/L GPB; T2, 5 g/L GPB; T3, 2 g/L autoclaved GPB; T4, 5 g/L autoclaved GPB; T5, 2 g/L GABA; and T6, 5 g/L GABA. In addition, 27 Hanwoo steers (602.06±10.13 kg) were subjected to a 129-day feeding trial, during which they were fed daily with a commercially available total mixed ration that was supplemented with different amounts of GPB-produced GABA (control, no additive; T1, 2 g/L GPB; T2, 5 g/L GPB). The degree of marbling was assessed using the nine-point beef marbling standard while endotoxin was analyzed using a Chromo-Limulus amebocyte lysate test.Results: In regard to in vitro rumen fermentation, the addition of GPB-produced GABA failed to significantly affect pH or total gas production but did increase the ammonia nitrogen (NH3-N) concentration (p<0.05) and reduce total biogenic amines (p<0.05). Animals fed the GPB-produced GABA diet exhibited significantly lower levels of blood endotoxins than control animals and yielded comparable average daily gain, feed conversion ratio, and beef marbling scores.Conclusion: The addition of GPB improved in vitro fermentation by reducing biogenic amine production and by increasing both antioxidant activity and NH3-N production. Moreover, it also reduced the blood endotoxin levels of Hanwoo steers.
