NOTE: Where experimental data are lacking, values typeset in bold italics represent an estimate based on values obtained for other ages or related species.

^aFinal body weight.

^bThese are typical dietary energy concentrations for diets based mainly on corn and soybean meal, expressed in kcal MEn/kg diet.

^cChickens do not have a requirement for crude protein per se. There, however, should be sufficient crude protein to ensure an adequate nitrogen supply for synthesis of nonessential amino acids. Suggested requirements for crude protein are typical of those derived with corn-soybean meal diets, and levels can be reduced somewhat when synthetic amino acids are used.

^dThe calcium requirement may be increased when diets contain high levels of phytate phosphorus (Nelson, 1984).

Bảng 7. Nhu cầu dinh dưỡng của gà Leghorn đẻ (trong thức ăn hỗn hợp 90% VCK)

NOTE: Where experimental data are lacking, values typeset in bold italics represent an estimate based on values obtained for other ages or related species.

^aGrams feed intake per hen daily.

^bBased on dietary MEn concentrations of approximately 2,900 kcal/kg and an assumed rate of egg production of 90 percent (90 eggs per 100 hens daily).

^cItalicized values are based on those from white-egg layers but were increased 10 percent because of larger body weight and possibly more egg mass per day.

^dLaying hens do not have a requirement for crude protein per se. However, there should be sufficient crude protein to ensure an adequate supply of nonessential amino acids. Suggested requirements for crude protein are typical of those derived with corn-soybean meal diets, and levels can be reduced somewhat when synthetic amino acids are used.

^eItalicized amino acid values for white-egg-laying chickens were estimated by using Model B (Hurwitz and Bornstein, 1973), assuming a body weight of 1,800 g and 47 g of egg mass per day.

^fThe requirement may be higher for maximum eggshell thickness.

^gThe requirement may be higher in very hot temperatures.

NOTE: Where experimental data are lacking, values typeset in bold italics represent an estimate based on values obtained for other ages or related species.

^aThe 0- to 3-, 3- to 6-, and 6- to 8-week intervals for nutrient requirements are based on chronology for which research data were available; however, these nutrient requirements are often implemented at younger age intervals or on a weight-of-feed consumed basis.

^bThese are typical dietary energy concentrations, expressed in kcal MEn/kg diet. Different energy values may be appropriate depending on local ingredient prices and availability.

^cBroiler chickens do not have a requirement for crude protein per se. There, however, should be sufficient crude protein to ensure an adequate nitrogen supply for synthesis of nonessential amino acids. Suggested requirements for crude protein are typical of those derived with corn-soybean meal diets, and levels can be reduced when synthetic amino acids are used.

^dThe calcium requirement may be increased when diets contain high levels of phytate phosphorus (Nelson, 1984).

Bảng 9. Nhu cầu axit amin của lợn sinh trưởng (cho ăn tự do, TAHH 90%VCK)

^aMixed gender (1:1 ratio of barrows to gilts) of pigs with high-medium lean growth rate (325 g/day of carcass fat-free lean) from 20 to 120 kg body weight.

^bAssumes that ME is 96% of DE. In corn–soybean meal diets of these crude protein levels, ME is 94–96% of DE.

^cCrude protein levels apply to corn–soybean meal diets. In 3–10 kg pigs fed diets with dried plasma and/or dried milk products, protein levels will be 2–3% less than shown.

^dTotal amino acid requirements are based on the following types of diets: 3–5 kg pigs, corn–soybean meal diet that includes 5% dried plasma and 25–50% dried milk products; 5–10 kg pigs, corn–soybean meal diet that includes 5 to 25% dried milk products; 10–120 kg pigs, corn–soybean meal diet.

^eThe total lysine percentages for 3–20 kg pigs are estimated from empirical data. The other amino acids for 3–20 kg pigs are based on the ratios of amino acids to lysine (true digestible basis); however, there are very few empirical data to support these ratios. The requirements for 20–120 kg pigs are estimated from the growth model.

Bảng 10. Dietary Amino Acid Requirements of Barrows and Gilts of Different Lean Growth Rates and Allowed Feed Ad Libitum (90% dry matter)^a

^aAverage lean growth rates of 300, 325, and 350 g/day of carcass fat-free lean represent pigs with medium, high-medium, and high lean growth rates from 20 to 120 kg body weight.

^bAssumes that ME is 96% of DE.

^cCrude protein and total amino acid requirements are based on a corn–soybean meal diet.

^dEstimated from the growth model.

^aDaily intakes of DE and feed and the amino acid requirements are estimated by the gestation model.

^bWeight gain includes maternal tissue and products of conception.

^cAssumes that ME is 96% of DE.

^aDaily intakes of DE and feed and the amino acid requirements are estimated by the lactation model.

^bAssumes 10 pigs per litter and a 21-day lactation period.

^cAssumes that ME is 96% of DE. In corn—soybean meal diets of these crude protein levels, ME is 95–96% of DE.

^dCrude protein and total amino acid requirements are based on a corn–soybean meal diet.
