This experiment was designed to study the effect of treating animals in early life and the mothers with an antimethanogenic compound (bromochloromethane, BCM) on rumen fermentation and microbial profiles and the persistency of the effects in the medium term. Eighteen goats giving birth to two kids were used. Nine goats were treated with BCM (M+ goats) after giving birth and over 8 weeks. The other 9 goats were not treated (M- goats). One kid per mother in both groups was treated with BCM (ch+) while the other was untreated (ch-), therefore resulting in four kids experimental groups: M+/ch+, M+/ch-, M-/ch+ and M-/ch-. Rumen samples were collected once from the mothers before weaning (at 8 weeks) and twice from the kids: at weaning and a month after weaning (while ch+ were still treated). BCM treatment on mothers did not affect either total amount of VFA or microbial counts, although the acetate:propionate ratio decreased as well as in the rumen of kids at weaning and a month later. In the rumen of kids, archaea and bacteria were affected by mother's treatment at weaning and by kid's treatment one month later, being lower the numbers in treated animals. Results suggest that an early intervention in the diet of young animals could have an effect on the development of the adult rumen ecosystem.
