This study was carried out to determine effects of 2 different stall types
and 3 different bedding materials on lactation length, milk yield and
some health problems in dairy herds. 477 lactation cows in 37 herds in
Bursa were examined. Mean of lactation length (day) and milk yield of
cows in the same herd was calculated to determine the effects. A t-test
was used to compare the means of free-stall or tie-stall herds, and oneway
ANOVA was used to compare the means of herds with concrete,
sand or rubber bedding. To test the association between stall type or
bedding material and some health problems, Chi-squared test was
used. According to the results, a significant difference was determined
between 2 stall types, in terms of milk yield (P < 0.01), while mean
of milk yield and lactation length of herds with rubber bedding were
found higher than the others (P < 0.01). The associations between stall
type and repeat breeding, dystocia and retained placenta were found
to be significant (P < 0.01, P < 0.01 and P < 0.05, respectively). Also,
it was found that repeat breeding and clinical mastitis were associated
with bedding material (P < 0.05 and P < 0.01, respectively). The results
of the present study indicate that by providing suitable stall type with
better bedding materials, animals can be kept healthy, expenditures on
medical treatments can be minimized and consequently, profitability
can be increased.
