Efficiency of influence of perlite and saponite on the level of harmful gases at tethered growing of cattle

Abstract

Goal. To find out the effectiveness of the influence of inorganic substances — perlite and saponite — on the level of such harmful gases as methane (CH4), carbon dioxide (CO2), ammonia (NH3), hydrogen sulfide (H2S), and nitric oxide (NO), in the air of the room at the year-round tethered growing of cattle. Methods. The study was conducted in the spring of 2024 based on the farm «Holub» (Lviv oblast) using the following methods: electrochemical — to establish the level of harmful gases in the room; selective average calculation — to determine average values and their errors; analytical — for analysis and substantiation of data. Results. It was found that the use of saponite helped to reduce the level of harmful gases in the cowshed by 21.3–35.3%, and the use of perlite by 16.9–21.1%. Therefore, a comparative assessment of the effect of these inorganic substances indicated that saponite was 4.4–14.2% more effective than perlite. The lower level of harmful gases in the room air correlated with the acidity of manure, which decreased to 6.01 and 6.34 units, respectively, in the case of the addition of saponite and perlite. Conclusions. The reduction of the level of harmful gases in the air of the cowshed for the use of such inorganic substances as saponite and perlite was experimentally confirmed and scientifically substantiated. The use of saponite will allow farms to reduce the negative consequences of their functioning and environmental impact, strengthen the genetic potential of animals, and therefore get the maximum profit.
