TAFLA 3. Aminósýruinnihald grasmjöls borið saman við
aminósýruþörf kjúklinga og svína.
The amino acid content of grass meal compared to the amino acid re-
quirement of chickens and pigs.
Aminósýra Amino acid Aminósýra i % af fóðri (þörf í % af heildarfóðri) % amino acid in feed (requirement as % of total feed consumed)

Tölurnar fyrir innihald grasmjöls af methionin, cystin og tryptophan
eru úr efnagreiningum á heyi gefnum upp í Tables of the amino acid in
foods and feedingstuffs (4), bls. 41, nr. 980. Hinar tölurnar eru eigin
efnagreiningar á grasmjölssýnishornum frá Reykhólum og Akureyri úr
grasi ræktuðu við áborin 120 kg N/ha.
The values for the content of methionin, cystin and tryptophan in
grassmeal are from Tables of the amino acid in food and feedingstuffs
(4), p. 41, no. 980. The other values for amino acid content in grass
meal are the values recorded for the samples from the experimental
plots receiving 120 kg N/ha at Reykhólar and Akureyri.
