on the mortality pattern of crossbred ‘Holdeo’ animals
was conducted at MAU,Parbhani.
The data of total 519 animal’s mortality were studied and
tabulated according to generation, season, sex, age, and cause
of mortality. The result revealed the F1 generation
proved more susceptible to the situation than interse progeny.
The highest overall mortality was observed in season S3 -summer
(9.28 per cent), season S1 -Monsoon
(7.43 per cent) and S2 -winter
(5.08 per cent) respectively. There was a non-significant effect
of sex on mortality pattern in all genetic groups; however,
higher mortality seems in female calves. Mortality due to cause
of Class-II (9.78 per cent) followed by Class-I (4.40 per cent),
Class-IV (3.99 per cent), Class-III (2.06 per cent) and Class-V
(1.56 per cent) respectively. The mortality percentage of
different age group was found as non-significant in all
Mortality, crossbred and Holdeo.
