Effect of chemical and biological preservatives and ensiling stage on the dry matter loss, nutritional value, microbial counts, and ruminal in vitro gas production kinetics of wet brewer’s grain silage

Abstract: This study evaluated the effects of chemical and biological preservatives and ensiling stage on spoilage, ruminal in vitro fermentation, and methane production of wet brewer’s grain (WBG) silage. Treatments (TRT) were sodium lignosulfonate at 10 g/kg fresh WBG (NaL1) and 20 g/kg (NaL2), propionic acid at 5 g/kg fresh WBG (PRP, 99%), a combination inoculant (INO; Lactococcus lactis and Lactobacillus buchneri each at 4.9 log cfu/fresh WBG g), and untreated WBG (CON). Fresh WBG was treated and then ensiled for 60… Show more

“…Westendorf and Wohlt [26] pointed out that the chief concern about the use of LBY relates to spoilage, which results in a less palatable product that may cause P. A. O. Alaru et al Open Journal of Animal Sciences health concerns to animals. The application of cost-effective preservatives may be a viable approach to preventing nutrient losses [10]. However, more precaution is necessary regarding food preservatives to avoid residual effects on animal by-products.…”

“…Liquid brewers' yeast is the second most abundant by-product from the brewery and distillery industries. It also has rich nutritional composition, making it a valuable feed for cattle [10]. The by-product is usually discarded into the environment as a waste product, causing water bodies pollution and increasing the biological oxygen demand (BOD).…”

“…First all of 20 g silage samples were mixed with 180 mL sterilized saline water, and serially diluted. The lactic acid bacteria and coliform bacteria were cultured on MRS agar plate and VRBA agar plate, respectively; yeasts and molds were counted on Rose Bengal Agar after being incubated at 28 • C for 2 days under aerobic condition [16,17]. To determine fermentation parameters, the sample (20 g) was mixed with 180 mL sterile water and kept at 4 • C overnight and then filtered via filter paper.…”
