Unformatted text preview: Dietary Treatments for Chick Experiment- ANSC324 Broiler chicks will be fed from 0-2 weeks of age. Therefore, nutrient requirements for a 0-2 wk old broiler should be used. Scenario #1. You work for a large-scale poultry operation that markets a 5 lb broiler at 42 d of age. With a 7d clean out period in between flocks this allows barns to be turned 7.4 times per year. Your boss would like to get this number closer to 8 turns per year. To do this, you need to decrease your days to market by about 3.4d, which represents a 6.9% improvement in feed efficiency. Being a cautious individual, you don’t want to make any drastic changes to the diet without doing a little experimentation first. So, you have obtained access to a set of petersime battery cages, where you can experiment with dietary changes that you think may improve feed efficiency. Your boss has asked you to: 1) Develop a hypothesis as to what dietary changes you think will improve feed efficiency 2) Design an experiment with 3 dietary treatments to test this hypothesis 3) Prepare the necessary diets 4) Run the experiment 5) Prepare a scientific poster summarizing the experiment and the results for your boss Scenario #1: Ingredients List, ANSC 324 (Spring 2004) (These ingredients are available for use. You may use all or some of these ingredients in your formulations.) 1. Akey Vit/min premix, 261610 (with choline) 2. Soybean meal, 44% 3. Soybean meal, 48% 4. Meat and Bone Meal 5. Corn gluten meal 6. Menhaden fish meal 7. Soybean hulls 8. Dehydrated alfalfa meal (17%) 9. Blood meal (spray dried) 10. Ground corn 11. Salt 12. Lysine-HCl 13. DL-Methionine 14. L-Threonine (98.5% Thr) 15. L-Tryptophan (98.0% Trp) 16. Soybean oil 17. Limestone 18. Dicalcium phosphate 19. Monocalcium phosphate 20. Natuphos phytase (contains 600 U of phytase/g) Dietary Treatments for Chick Experiment- ANSC324 Broiler chicks will be fed from 0-2 weeks of age. Therefore, nutrient requirements for a 0-2 wk old broiler should be used. Scenario #2. As a side hobby, you started raising free-range broilers. You quickly discovered that there was a fairly large niche market for these birds, and that a substantial premium could be made versus more conventional rearing. The biggest problem or obstacle that you have run into is that it has been difficult to find a packing plant willing to handle the smaller number of birds that you produce compared to a larger integrated producer. Finally you have identified a small...
