at the concentration of 800 g/d (Table 5), which may be due to a lower starch infusion level and an experimental period which lasted from early to mid-lactating period.
reported that critical threshold of [beta]HBA for metabolic disorders such as displaced abomasums
, clinical ketosis, metritis or retained fetal membranes are 0.
If farmers get the nutrition right to prevent displaced abomasums
they will also increase their milk production as cows with this condition are just the tip of an iceberg,' he suggests.

Larger particles of food that pass through the reticulo-omasal orifice are retained between the omasum's folds, with fluid components being transported comparatively rapidly to the abomasum
Motility of the rumen and abomasum
Microbial organic matter (MOM) and microbial nitrogen (MN) leaving the abomasum
were calculated using purines as a microbial marker (Zinn and Owens, 1986).
8), but soluble and released at the more extreme pH conditions found in the abomasum
In addition, numerous studies have recently demonstrated that feeding cattle diets rich in highly degradable carbohydrates results in disorders such as acidosis, fatty liver, laminitis, liver abscesses, displaced abomasum
, and bloat (Nocek, 1997; Ametaj et al.

Once the contents had been removed, the weight of rumen, reticulum, omasum, abomasum
, large and small intestines, liver, heart, spleen, lungs, and trachea was measured.
The digestive tract (esophagus, rumen, reticulum, omasum, abomasum
, and small and large intestines) content was removed before the digestive tract was flushed with tap water, the excess water was then stripped manually, and weighed again.
