New feed ingredients affect carcass fat quality

As the quantity of Distillers Dried Grains with Solubles (DDGS) has increased in pig rations in North America so has concern over fat quality. It is well known that the use of DDGS increases the amount of unsaturated fat in rations. This has the potential to negatively influence carcass fat quality since carcass fat composition is affected by the type of fat in the diet.
The type of fat in a pig’s diet influences its carcass quality and measuring backfat is a good means to assess the... read more »

Distillers grains: Which residues are we afraid of?

The popularity of Dried Distillers Grains with Solubles (DDGS), the co-product of ethanol production, is increasing in Europe due to a shortage of protein raw materials. But apart from GM-issues, imports also need to be screened for antibiotics, since these products are used in the fermentation process to fight lactic acid bacteria that compete with yeast for the sugars to make ethanol. More alternatives to antibiotics are becoming available though. read more >

Fefac president: ‘Europe is the feed lab of the world’

“We, in Europe, develop the sustainable technologies that will help feed the world in the future,” said Patrick Vanden Avenne, president of the European feed manufacturers association Fefac at their 54th General Assembly in Bruges in early June. read more >

Pig MBM in broiler feed did not meet expectations

Wageningen UR Livestock Research studied the effect of the inclusion of MBM in broiler diets on performance, litter quality and external quality. Although it was expected that this would benefit performance and litter quality, the results of this study show that MBM could not live up to presumed expectations. read more >

Feeding strategies with DDGS to improve carcass quality

For most pork producers in North America the use of distillers dried grains with solubles (DDGS) is now common. However, research and on-farm studies have shown that while DDGS is an important ingredient, appropriate feeding strategies must be used to optimise both feed cost and carcass quality. Corn derived DDGS contains approximately 10% oil, which is rich in linoleic acid (C18:2), a polyunsaturated fatty acid that is primarily responsible for (undesired) soft pork fat. read more >

Formulating fish feed using earthworms as a protein source

Formulated feeds are complete feeds which supply all the nutrients necessary for optimal growth and health of the fish in culture practices. In many areas of the world protein sources are scarce and for formulating aquafeeds earthworms as a protein source might provide an alternative to common used raw materials. read more >
