The big advantages of L-Tryptophan

BETTTER GROWTH AND BETTER FEED EFFICIENCY

The effect of the balance among Lysine,Threonine and Tryptophan on the performance of piglet(10-30kg)

Lys	100(1.26)	100(1.26)	100(1.26)	(　):Percentage in diet
Thr	56(0.71)	65(0.82)	65(0.82)
Mel+Cys	60(0.75)	60(0.75)	60(0.75)
Trp	16(0.20)	16(0.20)	21(0.26)

Above experiment shows that if you add AJINOMOTO's L-Threonine and L-Tryptophan to adjust amino acid balance,weight gain can improve by 10%,and feed conversion by 5%

LOW-PROTEIN & LOW-COST

Limiting amino acids in a low-protein corn-soybean meal diet for starter pigs (4-8 weeks of age) (R.A.Easter: 1983)

L-Trp	-	-	-	0.05	0.05
L-Thr	-	-	-	-	0.13

18% CP corn-soybean meal diet for piglet feed can be reduced to 16% CP without loss in performance if L-Lysine HCL is provided. Also,if L-Tryptophan and L-Threonine are added,CP can be reduced further to 14%

BETTER EGG PRODUCTION

Hen day egg production in laying hens(Rhode Island Red & White Leghorn) fed diets with or without added L-Tryptophan(Trp) from 25 to 82 weeks of age. Beast diet contains 15.24% CP,0.64% Lysine and 0.15% Tryptophane.

Tryptophan deficiency adversely affects animal productivity,while Tryptophan digestibility of feed ingredients is generally low as shown in the above table.Therefore,we recommend addition of AJINOMOTO's L-Tryptophan as a safety margin of Tryptophan level in feed.

The reguirements listed are based upon corn-soybean meal diets.
Approximate protein levels required to meet essential amino acid needs. If cereal grains other than corn are used,an increase of protein by 1 or 2 percent may be required.
Methionine can fulfill the total requirement;cystine can meet at least 50 percent of the total requirement.
Phenylalanine can fulfill the total requirement;tyrosine can satisfy at least 50 percent of the total need for these two amino acids.
