The 1 hour seminar on chicken nutrition, say that 3 x fast, was interesting. Very good, concise and easy to understand.
I learned a few things, though the Blue Seal nutritionist said most information hasn't changed since we went to school. It's the micronutients and probiotics and prebiotics that really improves the health of the chicken and poultry now.
Blue Seal was doing a study using 2 pens. One given a higher dose of zinc, the control group was not given the higher dose of zinc. The Midwest heat had soared to 110 degrees. Only 2 birds died from the zinc supplemented group whereas all in the non-supplemented group died. The death of the birds was not intentional and the original study stopped right there for a re-do.
Chickens cannot digest roughages . So too much sunflower seed is not good for them. They eat grass for the sugars. Fish was taken out of the feed because people didn't want to feed fish to the poultry, but a good source of complete protein has not been replaced in the feed. Added methionine and lysine have been added instead.
Regarding our health, omega 3's and omega 6's are important and need to be in balance. While 3's are touted to be so good for us, the omega 6's that promote inflammation is important because this actually aids in the repair of tissue.
Oh, and more and more people are raising poultry! Didn't we already know that?? AND pigs.
