Ruminant mammals

Plant lipids generally have an even number of carbon FAs, while animal lipids include odd-numbered carbon chain FAs, and, in some cases, branched chain FAs formed by bacterial activity in the digestive tract of ruminant mammals [5,41]. Branched FAs can also be formed in low amounts from other kind of lipids as a result of microbial activity after burial.

Adverse effects of copper deficiency can be documented in terrestrial plants and invertebrates, poultry, small laboratory animals, livestock — especially ruminants — and humans. Data are scarce or missing on copper deficiency effects in aquatic plants and animals and in avian and mammalian wildlife. Copper deficiency in sheep, the most sensitive ruminant mammal, is associated with depressed growth, bone disorders, depigmentation of hair or wool, abnormal wool growth, fetal death and resorption, depressed estrous, heart failure, cardiovascular defects, gastrointestinal disturbances, swayback, pathologic lesions, and degeneration of the motor tracts of the spinal cord (NAS 1977). 

Ans. No. However, ruminant mammals possess bacterial flora which synthesize enzymes with the capability of hydrolyzing cellulose to its constituent glucose molecules.

Cobalt is an essential element for bacteria, algae and ruminant mammals. For other organisms, including monogastric animals, cobalt is essential, in the form of the essential compound vitamin Bj2 (cobalamin). Rumen microflora of ruminants synthesises cobal-amin from cobalt in the diet. Derivatives of vitamin Bj2 cobamides are cofactors of some enzymes, for example of methyhnalonyl coenzyme A mutase, glutamate mutase and methionin synthetase.
