Nutrition management Broiler

  1. 1. 9. NUTRITION MANAGEMENTBroiler Management Guide
  2. 2. Introduction• Broiler diets ▫ Energy ▫ Nutrients• Health and Efficient production
  3. 3. Introduction• Basic Nutritional Components ▫ Water ▫ Amino acids ▫ Energy ▫ Vitamins ▫ Minerals• To assure correct ▫ Skeletal growth ▫ Muscle disposition
  4. 4. Introduction• Factors affecting Nutrient content of the feed ▫ Ingredient quality ▫ Feed form ▫ Feed hygiene• If compromised ▫ Performance can be decrease
  5. 5. Introduction• Key Factors in selection of optimum diets ▫ Raw material availability and cost ▫ Separate sex growing ▫ Live weights required by market ▫ The value of meat and carcass yield ▫ Fat levels required by specific market ▫ Skin color ▫ Meat texture and flavor ▫ Feed mill capabilities
  6. 6. Introduction• Feed forms ▫ Mash ▫ Crumble ▫ Pelleted ▫ Extruded• Further processing is often preferable ▫ Improved in flock efficiency
  7. 7. Crude Protein• Requirements for amino acids ▫ Building blocks of protein• Proteins ▫ Structural components in tissues ▫ Feathers to muscle
  8. 8. Energy• Necessary for maintaining the bird’s basic metabolic functions and body weight growth• Metabolizable energy (ME) ▫ Energy content of poultry diets ▫ Gross amt of energy of a feed consemed minus the gross amount of energy excreted
  9. 9. Micronutrients• Vitamins ▫ Routinely supplemented ▫ Water soluble  B-complex vitamins ▫ Fat soluble  A, D, E and K  Can be stored in liver and other parts
  10. 10. Micronutrients• Minerals ▫ Inorganic ▫ Major elements  Ca, P, K, Na, Cl, S, Mg ▫ Trace elements  Fe, I, Cu, Mn, Zn, Se
  11. 11. Feed testing• Feed sampling ▫ Systematic approach ▫ ‘’best practice’’ policy• The analysis reflects the real nutrient content of feed ▫ If good sampling technique was done• Take sub-samples (eg 5) ▫ Combine into a composite sample ▫ 5 samples per each delivery of feed taken
  12. 12. Feed testing• Sampling from feed lines ▫ Not recommended ▫ Sifting of ingredients or feed will skew results• Samples should be stored in a refrigerator ▫ Recoded with date, feed type and delivery ticket number• If problem arises, feeds should be analyzed ▫ Reports should be compared with nutrient specifications for the respective diets
  13. 13. Phase feeding• Nutrient requirement ▫ Decline with broiler age• Starter, Grower and Finisher diets ▫ Incorporated into the growing program of broilers• Changes in nutrients should not be done abruptly on specific dates but rather continuously overtime
  14. 14. Phase feeding• The greater the number of feeds a bird receives, the closer to feed the birds to the requirement.• The number of feeds is limited by these factors ▫ Economic  Transportation cost  Farm capacity ▫ Logistical  Feed mill capacity
  15. 15. Phase feeding• Dietary concentrations are based on the objectives of the producer.• There are three (3) objectives of feeding broilers ▫ Most producers use a combination of these
  16. 16. Diet Type 1• Nutrient-rich ▫ To optimize live weight gain and feed conversion• Promotes additional carcass lipid content• Also, metabolic disorders• Diet cost will be high
  17. 17. Diet Type 2• Lowered energy content• Optimum crude protein and amino acid content• Results into less lipid gain but maximize lean mass production• Live weight and feed conversion ▫ Will be negatively affected• Cost per lean mass will be optimal
  18. 18. Diet Type 3• Low nutrient concentration• Result in lower live weight growth• Higher feed conversion• Cost per live weight may be optimum
  19. 19. Feed withdrawal• Special attention towards medication and vaccine withdrawal dates ▫ To ensure no residue retained in carcass at processing• Always keep records.
  20. 20. Supplement Whole Wheat feeding• Whole wheat to broiler chickens? ▫ Being practiced around the world ▫ Reduction in feed cost ▫ Improvements in gizzard development  Improved digestion  Ability to manipulate the nutrient intake
  21. 21. Supplement Whole Wheat feeding• Disadvantages? ▫ Reduced growth rate ▫ Reduction in lean gain ▫ Poorer uniformity  If adjustments in compound feed are not made
  22. 22. Supplement Whole Wheat feeding• Maybe added either in ▫ feed mill- ▫ farm- preferably due to flexibility if offers• Around day 7 or when birds weigh 160 g ▫ Begin supplementing ▫ Level of 1%-5% ▫ Inc to approx. 30%, gradual inc by 1-5%
  23. 23. Supplement Whole Wheat feeding• The maximum percent (30%) depends on ▫ Compound feed quality ▫ Nutrient density ▫ Wheat quality ▫ Desired performance ▫ Performance of individual flocks
  24. 24. Supplement Whole Wheat feeding• Important reminders!! ▫ Supplementation leads to dilution effect to the diet.. Make adjustments! ▫ Medications need to be adjusted ▫ Regular monitoring of bird live weight  To see the effects to the flock ▫ Supplemental whole wheat should be removed 48 hours before slaughter  To avoid contamination of carcass during eviceration
