Contextualization: Solid ruminal activators (SRA) that improve fermentation conditions in the rumen microorganisms of the cattle, used as feed additives, have gained importance in the nurturing of ruminants. They promote animal production rates and replace growth promoters, such as antibiotics, that can affect animal production and influence on their consumers microbiota; consequently, they can strongly affect human health.

 

Knowledge gap: The solid ruminal activators are important mitigators of the generation of greenhouse gasses because they improve the digestibility of fibrous and coarse foods, widely used in the feeding of ruminant species, which are important generators of greenhouse gasses.   

 

Purpose: In the present study, three SRA were inoculated, in different percentages (0, 10 and 15%), with a microbial preparation composed of lactic acid bacteria (LAB). They were evaluated      to assess the composition and microbiological quality of these food supplements.

 

Methodology: Multiple samplings were carried out throughout the manufacturing process and several chemical and microbiological analyzes of the samples were performed.

 

Results and conclusions: Supplements with crude protein (CP) values higher than 22%, low crude fiber content (CF) and in vitro dry matter digestibility (DVDM) higher than 80% were found in all cases. In addition, it was observed that SRA are innocuous from a microbiological point, which makes them a possible probiotic due to their high loads of LAB. In this sense, SRA are an efficient, biotechnological, alternative that could be used in cattle feeding to improve the use of forage and fibrous materials; also, they contribute to improve the environmental conditions because they support the decrease of greenhouse gasses.
