The evaluation chemical and microbiological parameters of total mixed ration (TMR) in dairy farm

The research was conducted in a 10 month period in a dairy cattle farm which has a total mixed ration (TMR) system. The material of the study consisted of samples taken from mixer wagons and feeders from TMR feed prepared in the enterprise. The mixer wagon capacity of the enterprise where the research is carried out is 1 ton and the composition of TMR is formed of meadow grass, straw, triticale, sunflower meal, corn silage, molasses, salt, vitamin mineral mixture and milk feed. pH, dry matter (DM), water soluble carbohydrate (WSC) microbiological analysis, lactic acid, yeast and mold analysis were performed. In each sampling period, ambient temperature and temperatures changes in feeders were recorded. As a result of the research, it is seen that feeder controls are more important especially during periods of high environmental temperature.
