3. Feeding Ducks;
4. Feeding Geese.

2. NUTRIENT REQUIREMENTS OF BROILER CHICKS
Nutrients Starter Grower Finisher
(0-10 d.) (11-24 d.) (25-slaughter)
Crude Protein, %
ME, MJ/kg
Lys, g/kg
Met + Cys, g/kg
Linoleic Acid, %
Ca, g/kg
P (available), g/kg
NaCl, %

3. How to express the nutrient requirements?
E.g. Setting up the CP content of the starter diet;
7-day-old chick
CP req.: 7.3 g/day;
DMI: 31 g/d;
CP content of the starter diet:
CP req./DMI = 7.3 (g/d)/31 (g/d) = 0.235
0.235*100 = 23.5%.

4. Protein:Energy ratio P:E ratio: protein (g/kg)/energy (MJ/kg).
But what type of protein and energy are used?
Type of protein and energy used in the given species.
Broiler chick (sarter): CP/ME =
235 (g/kg)/12.6 (MJ/kg) = g/MJ.

5. Groups of feeds used in poultry diets
Energy sources (60-70%):
- cereal grains,
Protein sources (30-40%):
- legume seeds,
- extr. oilseed meals,
Supplements:
- vitamins, minerals,
- amino acids, energy, etc.;
Physical form of diets:
- mash, crumbles, pellets.

6. CEREAL GRAINS

7. Corn - Proportion in Diets: 40-60%, - ME: 14 MJ/kg (the highest),
- CP: 10% (the lowest),
- Lys: 2.7 g/kg,
- EE: 4% (2% Linoleic acid),
- taste,
- yellow pigments: skin, egg yolk.

8. Wheat - Proportion in Diets: 10-30%, - CP: 13-14% (the highest),
- Pentosans,
- less palatable to birds.

9. Barley - Proportion in Diets - 5-20%, - CF: 5-6%, - ß-glucans,
- for pullets.

10. Oat - ME: 10.7 MJ/kg (the lowest), - CF: 12% (the highest),
- good dietetic effect,
- EE: 5% (the highest) – 1.5% linoleic acid (!),
- for pullets, heavy type birds, geese.

11. LEGUME SEEDS

12. Field Peas
- proportion in diets: 15-20%,
- CP: 20-25% (the lowest).

13. Horse Bean - proportion in diets: 15%, - CP: 25-30%,
- poor in Met (6 g/kg),
- antinutritional factors (vicin, convicin, tannin).

14. Lupins - proportion in diets: 15%, - CP: 35-40% (the highest),
- antinutritional factors (lupinin, Lupanin) < 0,08%,
- lupinosis (liver damage).

15. Soybeans - „full-fat” soybeans, - EE: 20%
- rich in linoleic and linolenic acids (85 g/kg),
- antinutritional factors (trypsin inhibitors) heat treatment is required
- energy source.

16. EXTR. OILSEED MEALS

17. Extracted Soybean Meal
- Proportion in Diets: 10-40%,
- CP: 45-50%,
- Lys: 30 g/kg, Met: 15 g/kg  Met suppl.  BV,
- antinutritional factors (e.g. tripstrypsin inhibitors)  heat treatment is required.

18. Extracted Sunflower Meal
- Proportion in Diets: 5-10%,
- CP: 30-45%,
- Lys: 11.5 g/kg, Met: 13.5 g/kg  Lys suppl.  BV,
- CF: 12-30% (!),
- not in starter diets.

19. Extracted Rapesed Meal
- Proportion in Diets: 10-20%,
- CP: 35-40%,
- Lys: 10 g/kg, Met: 16 g/kg  Lys suppl.  BV,
- CF: 10-15%,
- antinutritional factors (mustard oil, eruic acid, tannic acid),
- 00 or 000 types.

20. Dilution of Energy Density
WHEAT BRAN
- CP: 16%,
- CF: 10-12%,
- ME: 10.0 MJ/kg,
- pullet diet.

21. Dilution of Energy Density
ALFALFA MEAL
- CP: 20%,
- CF: 25%,
- ME: 7 MJ/kg,
- pullet diet.
