
same podolic group of cattle
similar external conformation
recently underwent a similar
demographic reduction
•
Existence of long horned cattle in Latium reported since Roman
times (ancestors of the Maremmana?). Maremmana may be
found to trace back to Grey Steppe cattle which entered Italy in
large numbers during the 14th to 18th centuries.
•
Herdbook registration started in 1935 (total breed population
274,000 head).
•
During the 1930s and 40s exported to Hungary to improve the
Hungarian Grey.
•
Since 1945 head numbers have declined dramatically, due to
land reform and mechanization, and by the mid 1960s
extinction was predicted.
•
Breed recovered in 1965-75 for its ability adapt to the
environmental constraints of the hilly areas of the Maremma,
reaching 60,000 head in 1975.
•
In 1992 the total was estimated at 10,000, of which 4,000
females and 120 sires were herdbook registered.
Theories on breed origin
•imported by the Hungarian conquerors
in the 9th century from the Podolic area
•came from the South, because there is
an evidence of the presence of similar
cattle in Egypt and Italy
•domestication of the wild cattle
(Aurochs) in the Carpathian basin
Turkey Grey (Boz Step or Plevne)
Turkish Grey

Found in north western Turkey, this
breed is a tri-purpose breed: kept
for milk and meat as well as being
used as a work animal. The breed
came from the Grey Steppe type and
originated from the Iskar breed of
Bulgaria (Mason 1996). It is believed
that Hungarian Grey cattle are the
ancestor or relatives
How much Grey breeds are related?

 Piemontese

Italian meat breeds subjected to
different selection histories
SNPs genotyping

Approximately 100 single nucleotide
polymorphisms (SNPs) in genes
candidate for meat traits (from
Gemqual EU project) were genotyped
on individuals belonging to the 5
breeds.

Attribution of individuals to the
breeds
PCA
Conclusion I
I
Podolic cattle, despite their similar
morphology, are genetically distinct
breeds. This could be due either to a
different origin of the breeds or to the
consequences of the recent history, that
led to the selection and probably fixation
of genes.
Conclusion II
Ample genetic diversity exists within
breeds that could allow selection
without increasing inbreeding
