Two studies were conducted to investigate the effects of Biological Resonance Catalyst (BRC) as a feed additive on milk production performance and apparent total-tract digestibility in lactating Anglo-Nubian x Saanen goats. Nine (9) primiparous and nine (9) multiparous dairy goats on the early stage of lactation were used in a 56-day feeding trial and five-day digestibility trial following a randomized complete block design with parity as the blocking factor. Treatments for both experiments were the inclusion rate of BRC added on top of the basal diet as follows: 0g h-1 d-1, 0.77g h-1 d-1, and 1.44g h-1 d-1. Results showed that the supplementation of BRC had no effects (P>0.05) on dry matter intake (DMI), milk yield, milk protein, milk fat, milk total solids and SCC per period and for the duration of the experiment. Similar values (P>0.05) were also observed from the coefficient of digestion of gross energy (GE), organic matter (OM), crude protein (CP) and neutral detergent fiber (NDF) across treatments. The current study was not able to establish a positive effect on production performance and nutrient digestibility in dairy goats. In vitro studies should be performed to validate the mode of action of BRC with increasing inclusion rate.
