ABSTRAK
Tujuan peneitian ini adalah untuk menganilis komposisi mineral susu, komposisi asam amino
protein susu dan produktivitas per 305 hari masa laktasi pada hasil persilangan dibandingkan dengan
bangsa murni sapi lokal Ukrania. Penelitian dilakukan pada beberapa induk sapi perah Ukranian Black-
Spotted (UBS) dan hasil silangannya pada generasi pertama dengan Brown Swiss, induk-induk Uranian
Red-Spotted (URS) dan hasil silangannya pada generasi dengan bangsa Montbeliarde. Pada dua
peternakan terdapat masing-masing dua jenis bangsa. Komposisi mineral susu pada sapi hasil silangan
lebih tinggi dibandingkan dengan bangsa murni. Kadar lemak susu sapi hasil silangan lebih tinggi 0,08-
0,16%, protein lebih tinggi 0,15-0,22% dan kadar Ca dan P masing-masing 2,66-8,83 dan 2,12-7,81 g
susu. Protein susu pada induk hasil persilangan ditandai dengan komposisi asam amino yang lebih
seimbang (EAA) dan rasio yang cocok untuk pemrosesan. Jumlah EAA pada 100 g protein susu induk
hasil persilangan adalah 3,11-6,25% lebih tinggi dibandingkan dengan induk bangsa murni. Induk hasil
persilangan lebih tinggi dalam hal komposisi mineral susu dibandingkan induk bangsa murni.
Direkomendasikan penggunaan bangsa Montbeliarde atau
Brown Swiss pada peternakan komersial.

ABSTRACT
The aim of this study was to analyze the mineral composition of milk, the amino acid composition
of milk protein, and the productivity per 305 days of lactation in crossbred cows compared to pure-breed
local Ukrainian analogues. The research was conducted at cows of the Ukrainian Black-Spotted (UBS)
dairy breed and crossbred cows of the first-generation obtained as a result of crossing with Brown Swiss
breed and at cows of the Ukrainian Red-Spotted (URS) dairy breed and crossbred cows of the first-
generation obtained by crossing of the URS dairy breed with Montbeliarde breed. In both farms there
were two groups of pure-breed and crossbred cows-analogues. The mineral composition of milk and its
technological properties in crossbred cows were higher compared to the pure-breed analogues. The fat
content of milk crossbred cows exceeded by 0.08-0.16%, protein exceeded by 0.15-0.22%, and the main
trace elements include Ca and P – by 2.66-8.83 and 2.12-7.81 mg/100 g of milk, respectively. Milk
protein of crossbred cows was marked by a more balanced composition of essential amino acids (EAAs)
and their ratio suitable for processing. The amount of EAAs in 100 g of milk protein of crossbred cows
was 3.11-6.25% higher compared to local analogues. Crossbred cows dominated pure-breed analogues
by the mineral composition of milk. The authors recommend the use of Montbeliarde or
Brown Swiss
