Abstract

This study aims to examine the influence of feed heating on the volatile fatty acid (VFA), microbial protein, and ammonia concentrations in rumen fluid. The feed ingredients are a carbohydrate supply (corn), and a protein source (soybean meal) added to the basal ration through lactic acid bacteria fermentation. The livestock employed were Bligon goats weighing 25–29 kg and aged 1.5–2 years, fed by a combination of grass, concentrate (70:40), and additive feed. The present study was based on an in vivo examination of ruminal digestibility. The data were analyzed statistically using a split-plot design with two components. The first factor was feed treatment, which includes heating (soaking feed in 90°C water for five minutes under ambient air pressure) and non-heating. The second factor was ruminal fermentation time, consisting of 0 hours before and five hours after feeding. Sampling was done after treatment for two months. Each treatment was carried out with three replications. The results showed that heating did not significantly affect the total levels of VFA, acetate, propionate, butyrate, ammonia, and microbial proteins production. The fermentation time significantly affected the increase in propionate and butyrate fractions, but not for the total VFA levels, acetate fraction, ammonia, and microbial proteins. Propionate tended to increase by 55.52% for heated feed and 37.84% for non-heating feed. Butyrate tended to increase by 56.77% for heated feed and 26.32% for non-heating feed. Meanwhile, feed heating (non-heating) tended to cause a lower total VFA of 36.51% (60.54%), acetate of 23.43% (73.32%), ammonia of 17.98% (60.10%), and microbial protein of 4.17% (10.74 %). This study concluded that heating carbohydrate and protein as additive feed sources had not significantly affected changes in VFA, microbial protein, and ammonia levels. However, the heating effect tended to reduce the increase in total VFA levels, microbial protein acetate, and ammonia levels of rumen fermentation.
