Supplemental Effect of Lactobacillus Plantarum on the Growth Performance, Nutrient Digestibility, Gas Emission, Excreta Microbiota, and Meat Quality in Broilers

“…1gm of fresh excreta sample was taken and diluted in 9ml of 1% peptone solution and mixed using vortex mixer. The microbial analysis was done according to the procedure of Sampath et al (2021b). Around 17:00 (pm) fresh excreta samples (approximately 300 g) were randomly collected from (32 birds/treatment) (4 birds/ cage) the pooled well, and stored in an airtight plastic box of 2.6 L with a slight hole on one side, fasten tightly with adhesive tape and fermented at 25℃ for 7 days.…”

“…The color parameters such as redness, lightness, and yellowness standards of each sample (surface) were measured at 3 locations with a portable Konica Minolta CR-400 chroma meter (Osaka, Japan). The pH, water holding capacity (WHC), drip loss, and cooking loss were calculated following the methods of Sampath et al (2021b).…”

Yeast-Derived Products: The Role of Hydrolyzed Yeast and Yeast Culture in Poultry Nutrition—A Review

“…The use of HY in poultry is generally able to improve the growth performance in terms of the body-weight gain (BWG) and a better feed conversion ratio (FCR), with no evidence on feed intake (FI) and mortality [ 64 , 65 ]. The HY efficacy, anyway, seems variable, accounting for the different rearing stages of poultry; improved performance was obtained at the beginning of the rearing cycle [ 66 , 67 ] or during the grower period only [ 68 , 69 ].…”

“…Besides the rearing phase, the HY efficacy seems to be dependent on the amount included in the feed. Recent studies have evidenced it as graded inclusion levels, and, specifically, higher inclusion rates led to more positive results on the performance [ 64 , 65 ]. Interestingly, beneficial effects of HY supplementation (i.e., improved BWG and FCR) have also been reported in the progeny of broiler breeder hens fed 5 g/kg of HY [ 13 ].…”

“…Different authors have investigated the effect of HY on the Lactobacillus count, reporting a linear increase in the excreta and ileal digesta of broilers receiving 1 and 2 g/kg of feed HY [ 65 , 69 ], as well as in laying hens receiving 0.5, 1, 5, 10, or 30 g/kg of HY [ 90 ].…”
