Pig meat is not the first culprit that springs to mind when thinking of
he salmonella risk to human consumers. But it is still a risk and most
contamination arises at the farm level. Sarah Mellor caught up with
Hendrix UTD's Maarten van der Heijden in Amsterdam, where he was
presenting new data on salmonella control for pig farms.
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.
Of the major hurdles to successful
integration into the EU will be the loss of two of the staples of eastern
European animal production – meat and bone meal and antibiotic growth
promoters. In the last issue, Feed Mix reported on the advice available to
Polish nutritionists on coping with the EU's stringent nitrogen laws. Here,
some EU experts pass on their experience of surviving without AGP's and MBM.
Lipids are one of the most important
variables in meat quality and are especially vital to meat shelf life. Studies
show that the most effective way of prolonging shelf life and maintaining
quality is to introduce antioxidant protection through the diet.
So say Polish scientists, who are making
good use of byproducts of the fish processing industry by processing them and
feeding the final product to pigs. Not only does this compare well with meat
meal and soybean meal, but carcass characteristics are better.
Conjugated linoleic acid is causing a bit of a stir. Not
only is it reported to have health benefits for humans, but it has been used in
dairy cows to soften the texture of butter. In pork, softer fat is not a useful
property, but CLA’s effects on pork quality were found to be quite surprising.
Since the European ban of most traditional
antimicrobials and growth promoters in animal feed, many alternatives have been
discovered, tested and commercialised. Safe, innovative and powerful plant
extracts can fit perfectly into today's animal husbandry and will play
important roles in the sustainable husbandry practices of the future.
Supplementing
diets with minerals can become something of a lottery, as sources differ in
their bioavailability to animals. As environmentalists begin to turn their
attention to trace mineral pollution, our attention must also be focused on the
most efficient usage. Using chelated sources appears to give more predictable
utilisation to the animal and thus reduces excretion of excess.
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 pigs in the US state Utah that believed to have eaten feed contaminated
with melamine may be euthanized as a precautionary measure, state and local
authorities said.
