[36] [37] When looking at meat only, ruminants consume an average of 2.8 kg of human edible feed per kg of meat produced, while monogastrics need 3.2 kg. [36] [37] Finally, when accounting for the protein content of the feed, ruminant need an average of 0.6 kg of edible plant protein to produce 1 kg of animal protein while monogastric need 2 kg.
Agricultural productivity is an important component of food security. [4] Increasing agricultural productivity through sustainable practices can be an important way to decrease the amount of land needed for farming and slow environmental degradation and climate change through processes like deforestation .
Proteins are important to supply the essential amino acids for the development of body tissues like muscles, nerves, cartilage, etc. Meals from soybean, canola, and corn gluten are the major source of plant protein in poultry diets. Supplementation of minerals are often required because grains, which are the main component of commercial feed ...
The simpler C3 cycle which operates in most plants is adapted to wetter darker environments, such as many northern latitudes. [citation needed] Maize, sugar cane, and sorghum are C4 plants. These plants are economically important in part because of their relatively high photosynthetic efficiencies compared to many other crops. Pineapple is a ...
Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like spent grain from beer brewing .
Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
Those countries with excess or low-value land tend to grass-feed their cattle herds, while those countries with excess feed grains, such as the U.S. and Canada, finish cattle with a grain ration. Grain-fed cattle have more internal fat (i.e., marbling ) which results in a more tender meat than forage-fed cattle of a similar age.
A food-feed system is an integrated livestock-crop production system where crops grown on farms are harvested for human consumption and the crop-residues or by-products are used as feed for livestock. For example, intercropping of cowpeas between rows of cassava. The legumes can enrich soil fertility and enhance the crop productivity.
