Saccharomyces Cerevisiae Diet Supplementation Affects Nutrient Digestibility and Milk and Mozzarella Cheese Yield in Dairy Buffalo Cows During the Transition.

The aim of the trial was to evaluate the influence of diet supplementation with Saccharomyces cerevisiae on nutrient digestibility and milk and mozzarella cheese yield in buffalo cows during the transition period. Twenty buffalo cows in the last month of pregnancy were equally divided into two groups (control, C, and treated, T) homogeneous for parity and milk yield at the previous lactation. The diet of group T was supplemented with 100 g/head/day of a product containing Saccharomyces cerevisiae (Sc 47- CNCM I-4407) for 4 weeks before and after calving.

Potential use of Wolffia globosa powder supplementation on in vitro rumen fermentation characteristics, nutrient degradability, microbial population, and methane mitigation.

This study examined the potential of duckweed powder (DWP) on in vitro fermentation characteristics, nutrient degradability, microbial change, and methane (CH) production using in vitrostudy technique. This investigation used a 2 × 6 factorial arrangement in a completely randomized design (CRD) by different roughage-to-concentrate (R: C) ratios of 60:40 and 40:60 combined with DWP supplementation levels at 0, 2, 4, 6, 8, and 10% of the total dry matter (DM) substrate, respectively. There was an interaction effect by R: C ratios combined with DWP supplementations that changed gas production rate, pH value (4 h; h), volatile fatty acid (VFA) (8 h), in vitro dry matter degradability (IVDMD) at 12 h, and concentration of ammonium nitrogen (NH-N) (p < 0.

Bioefficiency of microencapsulated hemp leaf phytonutrient-based extracts to enhance in vitro rumen fermentation and mitigate methane production.

The objective was to assess the supplementation with microencapsulation of hemp leaf extract (mHLE) utilized as a rumen enhancer on in vitro rumen fermentation and to enhance the bioavailability of active compounds for antimicrobial action, particularly in protozoa and methanogen populations. The feed treatments were totally randomized in the experimental design, with different levels of mHLE diet supplemented at 0, 4, 6 and 8% of total DM substrate and added to an R:C ratio of 60:40. During fermentation, gas kinetics production, nutrient degradability, ammonia nitrogen concentration, volatile fatty acid (VFA) profiles, methane production, and the microbial population were measured.

Using Azolla (Azolla microphylla) leaf meal and phytonutrient powder on rumen fermentation efficiency and nutrient degradability using in vitro technique.

Objective: This work was to investigate the effect of using Azolla (Azolla microphylla) leaf meal and phytonutrient powder on rumen fermentation efficiency and nutrient degradability using in vitro technique.

Methods: All respective treatments were imposed in a 2 × 4 × 2 Factorial arrangements according to a completely randomized design (CRD). The first factor was two ratios of roughage to concentrate (R:C at 60:40, and 40:60), the second factor was Azolla (Azolla microphylla) powder (AMP) supplementation levels (0%, 3%, 6%, and 9% of the total substrate) and the third factor was Turmeric (Curcuma longa) powder (TUP) supplementation levels (0% and 2% of the total substrate).

Advantageous effects of rumen-protected phytonutrients from tropical plant extracts on rumen fermentation efficiency and methane mitigation using in vitro fermentation technique.

Objective: Tropical plants are composed of phytonutrients (PTNs) and are utilized for their capacity to manipulate rumen fermentation characteristics and methane production. The aim of this experiment was to determine the impact of microencapsulated phytonutrients-extracted from lemongrass and mangosteen peel (M-LEMANGOS), as well as crude protein levels on nutrient degradability, rumen ecology, microbial population, and methane emission in an in vitro study.

Methods: The treatments were randomly assigned in a 2 × 4 Factorial arrangement in a Completely randomized design.
