The use of agricultural land to grow feed rather than human food can be controversial (see food vs. feed); some types of feed, such as corn , can also serve as human food; those that cannot, such as grassland grass, may be grown on land that can be used for crops consumed by humans. In many cases the production of grass for cattle fodder is a ...
The advantages of silage as animal feed are several: During fermentation, the silage bacteria act on the cellulose and carbohydrates in the forage to produce volatile fatty acids (VFAs), such as acetic, propionic, lactic, and butyric acids. By lowering pH, these produce a hostile environment for competing bacteria that might cause spoilage. The ...
A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
The problem becomes more complicated as other feedstuffs containing animal by-products are still allowed to be fed to other non-ruminants (chickens, cats, dogs, horses, pigs, etc.). Therefore, at a feed mill mixing feed for pigs, for instance, there is still the possibility of cross-contamination of feed going to cattle. [44]
The oats are cooked in milk, water or a mixture of the two. Scottish traditionalists allow only oats, water and salt. [20] There are techniques suggested by cooks, such as presoaking, but a comparative test found little difference in the end result. [20] Various flavourings can be used and may vary widely by taste and locality.
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
Crop residues provide animal feed, while the animals provide manure for replenishing crop nutrients and draft power. These processes promote internal nutrient cycling and minimize the need for synthetic fertilizers and large-scale machinery.
