Sheep rumen metabolic development in response to age and dietary treatments.

Abstract: This study examined the time course of rumen metabolic development in the absence of solid feed consumption and the effect of delayed solid feed consumption on sheep rumen development. Twenty-seven lambs consumed milk replacer until slaughter at nine ages from 1 to 84 d (milk group). Three additional lambs consumed milk replacer from 1 to 48 d. From 49 d until slaughter at 84 d, these lambs were weaned onto solid feed (fed group). At slaughter, rumen contents were removed for VFA analysis and rumen epithelium … Show more

“…This relationship was not observed by Coverdale et al (2004). Lane et al (2000) found BHBA production to increase in 42-day-old lambs receiving milk alone or milk and concentrate. These observations suggest that the presence of VFA may not be the only factor inducing the development of ketogenesis, which may occur through ontogenesis or the action of other factors (Lane et al, 2000).…”

These observations suggest that the presence of VFA may not be the only factor inducing the development of ketogenesis, which may occur through ontogenesis or the action of other factors (Lane et al, 2000). This is perhaps the reason why no differences in serum BHBA concentrations were found between the groups, despite different proportions of Na-butyrate in the calf diets.…”

“…Quigley and Bernard (1992) reported that blood BHBA concentration between 28 and 42 days of age ranged from 0.22 to 0.62 mM/l, while in the same period, Suarez et al (2006b) observed much lower BHBA values, similar to those observed in the present study. Lane et al (2000) demonstrated a similar increase in BHBA production in 42-day-old lambs fed milk alone or milk and concentrate mixture, which suggests that the presence of VFA may not be the only factor inducing the development of ketogenesis, and it may occur via ontogenesis or as a result of other factors. According to Lane et al (2002), mRNA coding for acetyl-CoA thiolase, the first enzyme in the ketogenic pathway, increases with age regardless of the feeding used, while the mRNA level of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthetase, the second enzyme taking part in the regulation of ketogenesis, may be regulated by feeding only to 42 days of age, after which it increases 6-fold regardless of feeding and becomes stable.…”

“…Ruminal papillae of a captive one were in filiform, however, the papillae were tongueshaped in wild muntjac rumen. Reticulum and omasum shape were similar to domestic ruminant, but the reticulum laminae were shallower than that in cattle or goat (Zitnan et al 1998;Lane et al 2000). The abomasum mucosal laminae of captive muntjac were conspicuous than a wild one, suggesting higher development of abomasums in captive muntjacs.…”
