Ekermans adds that the feed efficiency of genetically improved animals is significantly higher than that of indigenous breeds. Since the early 1960s, the feed conversion ratio of broilers and porkers, for example, has more than halved, with modern broilers requiring about 1,6kg of feed for every kilogram of weight gained and porkers needing approximately 1,9kg to gain a kilogram.
Having an animal that is genetically feedefficient is not enough, however, as feed efficiency is also influenced by factors such as stress, environmental conditions, feed quality and ingredients, as well as the way in which the feed is provided. The animals should therefore be weighed regularly to determine if they are meeting targeted growth norms, as predefined by suppliers, and this growth should be counterbalanced by the volumes of feed given.
“Most farmers are good at measuring growth rates, but few keep track of the volume of feed given, unless they have large operations where feed intake is measured automatically. If you don’t know how much feed you’re giving, you won’t be able to determine your efficiency or identify irregularities,” says Ekermans.
AVOID STRESS
Stress may have a negative impact on both feed intake and digestion, so it should be prevented as far as possible.
“While diseases cause stress in animals, overstocking and the stocking of too many age groups in the same place are the biggest problems,” he explains.
