Transcript

  • 1. 9. NUTRITION MANAGEMENTBroiler Management Guide
  • 2. Introduction• Broiler diets ▫ Energy ▫ Nutrients• Health and Efficient production
  • 3. Introduction• Basic Nutritional Components ▫ Water ▫ Amino acids ▫ Energy ▫ Vitamins ▫ Minerals• To assure correct ▫ Skeletal growth ▫ Muscle disposition
  • 4. Introduction• Factors affecting Nutrient content of the feed ▫ Ingredient quality ▫ Feed form ▫ Feed hygiene• If compromised ▫ Performance can be decrease
  • 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. Introduction• Feed forms ▫ Mash ▫ Crumble ▫ Pelleted ▫ Extruded• Further processing is often preferable ▫ Improved in flock efficiency
  • 7. Crude Protein• Requirements for amino acids ▫ Building blocks of protein• Proteins ▫ Structural components in tissues ▫ Feathers to muscle
  • 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. 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. Micronutrients• Minerals ▫ Inorganic ▫ Major elements  Ca, P, K, Na, Cl, S, Mg ▫ Trace elements  Fe, I, Cu, Mn, Zn, Se
  • 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. 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. 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. 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. 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. 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. 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. Diet Type 3• Low nutrient concentration• Result in lower live weight growth• Higher feed conversion• Cost per live weight may be optimum
  • 19. Feed withdrawal• Special attention towards medication and vaccine withdrawal dates ▫ To ensure no residue retained in carcass at processing• Always keep records.
  • 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. Supplement Whole Wheat feeding• Disadvantages? ▫ Reduced growth rate ▫ Reduction in lean gain ▫ Poorer uniformity  If adjustments in compound feed are not made
  • 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. Supplement Whole Wheat feeding• The maximum percent (30%) depends on ▫ Compound feed quality ▫ Nutrient density ▫ Wheat quality ▫ Desired performance ▫ Performance of individual flocks
  • 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
