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]
Safer protocols to transition cows onto manglewurzel feed were then provided, making the entire process quite safe. [11] As with most foods, subsisting on solely one crop can produce dietary deficiency. The food shortages in Europe after World War I caused great hardships, including cases of mangel-wurzel disease, as relief workers called it ...
Feedlot and intensive finishing are intensive forms of animal production. Cattle are often "finished" here, spending the last months before their slaughter gaining weight. They are fed nutritionally dense feed, also known as "concentrate" or "filler corn", in stalls, pens and feedlots at high stocking densities in enclosure
Since 1960 average cow's milk production has increased from 5-kilogram /day (11 lb) to 30-kilogram /day (66 lb) by 2008, as noted by Dale Bauman and Jude Capper in the Efficiency of Dairy Production and its Carbon Footprint. The article points to the fact that the carbon footprint resulting from the production of a gallon of milk in 2007 is 37% ...
Notably, since livestock like cows spend much of their day laying down, comprehensive heat stress estimation needs to take account of ground temperature as well, [18] but the first model to do so was only published in 2021, and it still tends to systematically overestimate body temperature while underestimating breathing rate. [19]
The quality and quantity of usable meat depends on the animal's plane of nutrition, i.e., whether it is over- or underfed. Scientists disagree about how exactly the plane of nutrition influences carcase composition. [13] The composition of the diet, especially the amount of protein provided, is an important factor regulating animal growth.

Feeding behaviors are important for the dairy cow, as feeding is how the cow ingests dry matter. However, the cow must ruminate to fully digest the feed and utilize the nutrients in the feed. [34] Dairy cows with good rumen health are likely to be more profitable than cows with poor rumen health—as a healthy rumen aids in digestion of nutrients.
