Distributing TMR to a group of dairy cows. Total mixed ration (TMR) is a method of feeding beef and dairy cattle. A TMR diet achieves a wide distribution of nutrients in uniform feed rather than switching between several types. A cow's ration should include good quality forages, a balance of grains and proteins, vitamins and minerals. [1]
Dairy-herd milk production may be limited by the amino acid methionine; therefore, the amino acid is included in cattle rations to provide a well-balanced diet. [3] Normally a cow receives 10-20 grams of Mepron per day, depending on performance and ration composition. [4]

The nutritional quality of feed is influenced not only by the nutrient content, but also by many other factors such as feed presentation, hygiene, digestibility, and effect on intestinal health. [17] Feed additives provide a mechanism through which these nutrient deficiencies can be resolved, improving animal rate of growth, health, and well ...
Dairy cattle (also called dairy cows) are cattle bred with the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species Bos taurus. [1] Historically, little distinction was made between dairy cattle and beef cattle, with the same stock often being used for both meat and milk ...
Dietary allowances at the end take into account the availability of phosphorus within the diet and meet the requirements through supplementation with inorganic feed phosphates. In addition calcium and vitamin D levels must be optimized because phosphorus metabolism is closely linked to these and symptoms of deficiency can be intensified if ...
Cattle raised on a primarily foraged diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. The term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.
The role in fertility and reproductive diseases of dairy cattle highlights that organic forms of Zn are retained better than inorganic sources and so may provide greater benefit in disease prevention, notably mastitis and lameness. Animals are thought to better absorb, digest, and use mineral chelates than inorganic minerals or simple salts. [1]
