The objectives of this study were to 1) determine the variation nutrient digestion, plasma metabolites and oxidative stress parameters triggered by induced subacute ruminal acidosis (SARA); 2) evaluate ability pelleted beet pulp (BP) as a replacement for ground corn alleviate SARA. Eight Holstein-Friesian cows fed four diets during successive17-day periods: total mixed ration (TMR) containing 0% finely wheat (FGW) (W0); TMR 10% FGW (W10); 3) 20% (W20); 4) BP (BP10). SARA induction protocol...

As an important limiting factor, lignin hinders the utilization rate of maize straw in ruminants. CaO treatment increases feed digestibility by disrupting ester bonds between hemicellulose, cellulose, and straw. Our previous research found that corn may increase its altering rumen microbes' abundance. This study further investigated molecular mechanism to enhance also examined ongoing effects on metabolites. Rumen fluid was collected analyze microbial metabolites using liquid...

This study investigated the effect of tannin sources on nutrient intake, digestibility, performance, nitrogen utilization, and blood parameters in lactating dairy cows. Four multiparous Holstein cows were used a balanced 4 × Latin square design, with each period lasting 28 days. Cows randomly assigned to one four dietary treatments: Control diet (CON, totally mixed ration without supplements), control supplemented 3% bayberry condensed tannins (BCT), Acacia mangium (ACT), valonia hydrolyzed...

Ten ileal T-cannulated pigs (19.26 ± 1.06 kg) were used to evaluate the effects of a novel phytase on apparent digestibility (AID) AA and total tract (ATTD) hindgut disappearance DM, GE, CP, crude fiber, NDF, ADF as well minerals balance. Pigs fed in duplicated 5 × 4 incomplete Latin square design (5 diets with periods). Each period consisted 5-d adjustment followed by 3-d collection feces urine then 2-d digesta. The included P-deficient basal diet (0.43% Ca 0.38% P) that was supplemented 0...

The mutton quality of Chinese Tan lambs (Ovis aries) has declined as feeding patterns have shifted from pasturing to pen rationing. While pen-fed can enhance the growth performance sheep, it falls short in terms meat attributes such color and tenderness. Furthermore, compared pen-fed, pasture-fed husbandry increases proportion oxidative muscle fibers, decreases glycolytic reduces LDH (lactate dehydrogenase) activity. Mutton is affected by fatty acids, rumen microorganisms play a role...

Forages are vital in maintaining the dietary structures of ruminants, and reducing their costs is important for improving dairy production efficiency. Thus, this study investigated effects forage types on dry matter intake, production, rumen fermentation, microbial profile peak-lactating cows. Eight cows (600 ± 25 kg) with days milk (60 10 days) were assigned to four groups using a replicated 4 × Latin square design: OG (oat hay + alfalfa corn silage concentrate), CW (Leymus chinensis AS...

Currently, information available on the comprehensive changes in rumen bacteria and metabolites of yaks fed high-grain diets is limited. This study aimed to investigate effects diet feeding blood metabolites, microbiome, metabolomics by using 16S rDNA gene sequencing liquid chromatography–mass spectrometry (LC/MS). Here, fourteen healthy male (body weight, 249.61 ± 8.13 kg) were randomly assigned two different diets: a hay (0% grain, CON, n = 7), or (70% HG, 7). At 74th day treatment,...

The aims of the experiment were to investigate variation in ruminal fermentation, milk performance and fatty acid profile triggered by induced subacute acidosis (SARA); evaluate ability beet pulp (BP) as a replacement for ground maize order alleviate SARA. Eight Holstein-Friesian cows fed four diets (total mixed rations) during successive periods (each 17 d): (1) without wheat (W0); (2) with 10% finely (FGW) (W10); (3) 20% FGW (W20); (4) pelleted BP (BP10). Inducing SARA diet W20 decreased...

The present study investigates the effect of 50 mL AMCB taken daily as a dietary supplement on rumen fermentation, microbiota, and production performance 40 Holstein dairy cows in transition period with 2.76 ± 0.48 parity 650 25 kg body weight. supplementation stabilized pH, improved microbiota richness partial probiotic colonization, considerably increased dry matter intake, milk production, protein content, yield. Moreover, after calving, reduced serum blood urea nitrogen, malondialdehyde,...

We evaluated the difference between rumen bacteria in Tan sheep fed either by grazing or a feedlot. The aim was to provide theoretical basis for ruminant nutrition and meat quality based on fermentation. Twenty-four three-month-old were randomly equally divided into two groups, group ration group. Five of each selected slaughter at six months age. Ruminal contents collected assessed identify bacteria, [...]

Supplementation with saccharomyces cerevisiae culture products (SCs) has shown effectiveness in alleviating or improving the health and productivity of ruminants at a high risk digestive metabolic problems as consequence their physiological state feeding system (i.e., Holstein cows during peak lactation). However, effects SC supplementation on ruminal digestion microbial population are not yet well-understood. Hence, this study aimed to contribute knowledge vitro nutrient digestibility...

Calf diarrhea causes huge economic losses to livestock due its high incidence and mortality rates. Alkaline mineral complex water is an alkaline solution containing silicon, sodium, potassium, zinc, germanium, has biological benefits therapeutic effects. This study aimed evaluate the impact of supplementation on health calves investigate effect neonatal calf serum variables liver transcriptome. Sixty Holstein (age 1.88 ± 0.85 days, weight 36.63 3.34 kg) were selected randomly divided into...

To study the effects of mannan oligosaccharides (MOS) on rumen fungal flora dairy cows, four lactating Chinese Holstein cows were randomly divided into two groups in two-stage 2 × cross-over design.The experimental group (MT) was fed with a basal ration and MOS perfused orally 60 g/(d head).The control (CK) ration.The fluid collected through oral cavity using negative pressure suction device.50ml every cow each time respectively before feeding (0 h) 2h, 4h 6h after day.The fungi tested by...

Alkaline mineral complex buffer can improve rumen fermentation and affect the microbiota of dairy cows. Here, we studied effects alkaline on serum immunity indexes, newborn calves.
