On-farm trials of a new feeding process have shown it is possible to improve
profitability in finisher pigs simply by changing the way feed diets are
delivered to feeders.
Feeding dried distillers grains with solubles (DDGS) to nursery and
grow-finish pigs has variable effects on growth performance, according to
studies by the Kansas State University.
Accurate
feeding can boost the genetic performance of high lean pigs. Established
nutrient requirements often do not match these pigs' potential. Especially
vitamins and macro minerals are under provided. Research at IowaStateUniversity showed the deficiencies.
Research by
Dr T Stahly at Iowa State University
indicates that the current NRC (1988) estimates of dietary pantothenic acid are
sufficient for maximum growth of pigs. Pig genetics though have developed
through the years and higher inclusions of the vitamin create leaner pigs with
less back fat and higher weight gains.
Australian researchers say adding fishmeal to finisher
pig diets can reduce saturated fat and increase levels of beneficial long-chain
omega-3 fatty acids in pork.
A lack of vitamin B3 is probably the cause for bone
problems, difficulties in walking and milk production in sows, according to
recent research by Dutch feed company ForFarmers.
The pork industry is continually seeking alternative ingredients for use
in pig diets, either as a means of diversifying rations -and thus reducing cost-
or to achieve a final pork product that meets certain specifications. Lentils
and flaxseeds are among these ingredients, according to experiments done by the
Prairie Swine Centre.
The Australian pork industry wishes to develop a closer relationship with
farmers willing to specialise in growing field peas and non-traditional lupin
varieties for use in pig diets.
As the use of corn for ethanol grows, pork producers are
asking about the use of co-products from the ethanol-making process. Iowa Pork
Industry Center (IPIC) director John Mabry said a new fact sheet on one
co-product, distillers dried grains with solubles (DDGS,) will provide some
much-desired information.
