The value of the lamb meat in human nutrition
Krishtafovich, V1, Krishtafovich, D2, Surzhanskaya, I3, Marakova, A4, Vorobieva, D5.
The samples of lean tissue of 6 and 8 months old lambs of various breeds have been chosen
as data for meat nutrition value study. We have found out that meat of purebred and crossbred
sheep (both 6 and 8 month old) has high biological value. However, it should be noted
that lamb meat of animals from the first group (Bakur pure breed (B) and Bakur-Edilbaev
crossbreed (BxE)) contains slightly more proteins than lamb meat of animals from the second
group (Stavropol pure breed (S) and Stavropol-Edilbaev crossbreed (SxE)), and that meat of
crossbreeds of both studied group also contains more proteins that meat of purebred animals.
We have not found any significant impact of breed and age of animals on content of most amino
acids excluding lysine as lamb meat of animals from S and SxE group contains more lysine
compared to meat of animals from B and BxE group (both 6 and 8 months old). According
to test results, 100 g of lamb meat produced from 6 months old animals of group B provides
18.3 – 33.6 % of the required amounts of essential amino acids, lamb meat produced from the
similar animals of group BxE provides 20.3 – 35.8%; group S – 13.6 – 48.3%; group SxE –
14.2 – 50.3%. We also found out that limiting amino acids of the protein of lamb meat from
two studied animal groups (B and BxE; both 6 and 8 months old) are valine, phenylalanine and
tyrosine. We have not found any limiting amino acids in the protein of lamb meat of animals
from groups S and SxE (both 6 and 8 months old). Amino balance/imbalance coefficient
indicates that amino acid content of lamb meat protein for all studied animal breeds (B, BxE, S
and SxE) and ages (6 and 8 months old) is rather balanced compared to ideal reference protein.
