The crosses had a higher milk yield but lower
fat content. At the end of the last and early in this century Danish
Red bulls were imported and used on the Angeln crosses and on the
local cattle.
The long-term breeding of the crosses inter
se with systematic selection for milk yield and fat content ensured
the development of highly productive cattle.
Since 1885 the best animals were registered and the first herdbook
was published in 1911. In 1947 the breed was given a new name -
Red-Brown Latvian. By 1980 numbers had reached 1 417 000 head.
These cattle vary in color from light-red
to dark-red. The head, neck and legs are often darker. They have
a strong constitution. The head is small, light and moderately long.
The skeleton is light, chest deep, body long, rump slightly raised,
udder usually well developed.
The best herds have marked dairy features. The basic measurements
of mature cows (in cm) are: withers height 129.6, chest depth 71.1,
chest girth 193.3, oblique body length 163.7, cannon bone girth
18.0 (National Herdbook , vol. 29, 1983).
The live weight of mature pedigree cows is
520-560 kg and that of bulls is 750-850 kg, going up to 1000 kg.
The milk yield of purebred Latvian Brown cows is high. The average
milk yield of the mature cows recorded in Volume 29 of the Herdbook
(1983) in their best lactation was 4537 kg and the fat content 4.28%.
The average yields of the nearest female
ancestors of the bulls recorded in Volume 29 of the National Herdbook
were 5970-6036 kg of milk and the fat content was in the range 4.38-4.73%.
The champion milk producers are: Nadze 8977
- 8457 kg milk with 3.93% fat; Yetse 6320 - 8170 kg, 4.21%; Grieta
4915 - 8113 kg, 4.26%; Roya 5212 - 8021 kg, 4.10%.
As a genetic resource for Latvia, Latvian Brown cattle are of primary
importance: they account for 99% of all cattle in this country.
The breed includes 4 major lines. in the improvement of Latvian
Brown cattle much importance has been attached to line breeding.
In 1979 a new breeding line was tested and
approved; it was named BL-1 (Brown Latvian No. 1). The number of
the BL-1 line is over 50,000 head.
This line is being developed in four branches
by the assortative mating of sires to cows from the best families
and by periodical moderate inbreeding. The major selection herds
belong to the breeding centers Vetsautse, Sigulda and Sarkanais
Octobris.
The BL-1 cows are noted for their harmonious
conformation. The udder is large, glandular, usually cup-shaped
or spherical with equally developed quarters (average index is 45%).
The milk yield of the cows in the selection
group is 5287 kg; fat content averages 4.16%, and protein content
3.45%.
There are many champions in this line; they
combine high yield with increased fat content: Undra 6088 - 4th
lactation, 9298 kg milk, 4.75% fat, 3.84% protein: Baka 3469 - 4th,
8544, 4.82%, 4.05%; Dalasa 4044 - 8th, 10 106, 3.76%.
The Latvian Brown breed of cattle is being
improved with the aim of increasing milk yields to 5000 kg with
the same fat and protein content and to meet the requirements of
the industrial methods of cattle management.
