Milk fat yield affects the price received for milk by dairy farmers, and given the rising feed costs, maximizing diet digestibility is critical for the economical viability of dairy farms. Although feeding animal-vegetable fat or coconut oil to dairy cows can increase energy intake, they sometimes cause milk fat depression (MFD). Feeding monensin has been found to increase feed efficiency and m...

It has been known for decades that microbial fermentation within the rumen is critical to postnatal rumen epithelial growth and maturation in ruminants, but the underlying mechanism is largely unknown. In this study, we determined the effect of rumen fluid, which should contain all products from rumen fermentation, on growth of rumen epithelial cells in vitro. Addition of 10% rumen fluid from c...

This paper focuses on dietary approaches to control intramuscular fat deposition to increase beneficial omega-3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid content and reduce saturated fatty acids in beef. Beef lipid trans-fatty acids are considered, along with relationships between lipids in beef and colour shelf-life and sensory attributes. Ruminal lipolysis and biohydroge...

1. [3H]leucine infused directly into the rumen of sheep labelled microbial protein and, when compared with the specific activity of the rumen free-leucine pool, indicated that 50% of the bacterial protein leucine originated from the rumen free-leucine pool. 2. The lower limit for bacterial protein turnover in the rumen was 0.37/d when calculated as the difference between the specific rate of di...

Assessment of the rumen fluid is an ancillary examination technique used in the clinical examination both of the individual bovine patient and at population level. The specific function and structure of the rumen makes ruminants different from other animals. Therefore, it logical to assess the rumen in detail when confronted with a bovine patient. Assessment of the rumen fluid is essential to a...

The potential for plant-origin essential oils to modulate rumen functions reducing bio-hydrogenation of fatty acids and methane production has been a significant area research in recent times. This study investigated the effects supplementation garlic (Allium sativum) have on vitro acids, methanogenesis fermentation characteristics total mixed ration buffalo with aim enhancing conjugated linole...
