[QUOTE="happycows, post: 2311970, member: 722"] Butterfat production can be compromised when rapidly digestible grass is consumed; due to the high sugar content of the summer grass and also the lack of effective fibre present in the summer grass. Butterfat is derived from acetate which is produced when bacteria breaks down fibre, but because rapidly digestible grass has low effective fibre it produces little acetate and as a result hinders butterfat production. The rumen environment is also very important to butterfat production. As grass has a lack of structural fibre, saliva production is reduced as fewer cows will be “chewing the cud” which causes rumen pH to drop leading to sub-acute rumen acidosis (SARA). SARA is a disorder of ruminal fermentation that is characterised by extended periods of depressed ruminal pH (below 5.5-5.6). SARA may not be as serious as acute acidosis, however, overtime it can act as a gateway to many other issues; low rumen pH can cause damage to the lining of the cow’s rumen which in turn can have a negative effect on both feed intake and feed digestion leading to depressed milk production and a negative impact on health as well as fertility. Low milk fat can be a sign of cows suffering from SARA. Other symptoms to watch for include loose dung with gas bubbles, less than 60-70% of cows chewing the cud, poor rumen fill and loss of body condition. [/QUOTE]
