Feed represents most of the price of producing a marketed pig and it may be affected by a wide range of components, together with genetics, well being and administration. One issue that’s typically ignored is the manufacturing of the feed. It could appear easy, however there are a number of areas to contemplate and numerous measures accessible to enhance feed effectivity.
Earlier than making the feed
Feed that’s designed for greatest feed effectivity begins with the usage of high-quality substances. Various substances are sometimes used to decrease feed prices, however they could enhance the variation in high quality going into the feed. Substances ought to be visually evaluated for injury earlier than utilizing them. A hidden concern is mycotoxins, notably in corn and distillers’ dried grains with solubles (DDGS). Corn ought to be examined for mycotoxins in geographic areas the place mycotoxins are identified to be current. (Alltech’s regional harvest analyses and Mycotoxin Administration program are good sources for that data.) If DDGS are used as a feed ingredient, all the time take a look at them for mycotoxins.
The formulation software program ought to comprise appropriate nutrient values for substances and proper nutrient specs for every section of manufacturing, in order that correct feed formulation will be created. This consists of utilizing nutrient values for digestible amino acids, accessible/digestible phosphorus and internet power. Using enzymes ought to be thought of as a way to extend digestibility of feedstuffs and enhance feed effectivity in swine manufacturing.
Making the feed
One of many largest impacts on feed effectivity is the particle dimension of the grain. Sometimes, corn is processed to be 500–700 microns in dimension, with a normal deviation of lower than 2.2, to assist guarantee consistency of particle dimension. Each curler and hammer mills can obtain this, however curler mills often present a extra constant grind with fewer effective particles. Analysis has proven that for each 100-micron lower in grain particle dimension, feed effectivity improves 1.0–1.2% in grow-finish swine. The aim of maximizing feed effectivity with a uniform, finely floor feed should be balanced towards the power price, feed flowability and elevated danger of gastric ulcers.
A mixer effectivity take a look at is an effective means to make sure that all substances are being blended appropriately to make a uniform last feed. Improperly blended feed can lead to poorer feed consumption, development and feed effectivity.
Pelleting feed will enhance feed effectivity if the pellets have good sturdiness. Analysis has proven that as the share of fines will increase, the feed conversion enchancment decreases, and with 60% fines, there isn’t any advantage of pelleting over mash.
After making the feed
A very good high quality assurance program, together with retained feed samples, will assist with analysis of feed high quality in addition to offering samples for later evaluation if wanted. Feeds ought to be analyzed for at the least protein, calcium, phosphorus, salt and one hint mineral regularly to make sure that an precisely formulated and manufactured eating regimen is delivered to the pigs.
A significant potential supply of decreased feed effectivity is poor feeder administration that permits for elevated feed wastage. The feed pan ought to have about 50% protection with feed to steadiness straightforward consumption with decreased feed wastage. If pelleted pig diets are used, the variation in share of fines can create a scenario the place extra time administration is required within the barn to attenuate feed wastage.
A feed price range that precisely prescribes the quantity of feed for every section of manufacturing will steadiness desired feed effectivity with feed price per pig. Carry out a closeout analysis to match the precise consumption of every eating regimen section with the projected quantity after which regulate as wanted to maneuver the pigs to the lower-cost diets.
Feed manufacturing for economical feed effectivity is a vital a part of an general pork manufacturing plan. The variety of components concerned in correct, high-quality feed being delivered to pigs reminds us that diligence to the small print will help enhance profitability.
