  Thirty one Holstein Friesian cows were allocated to two groups. For a period of 7 weeks, twice a week, the behavior of each cow was registered for 9 h (07:00, 09.00, 10.00, 11.00, 13:00, 14.00, 15.00, 17.00 and 19:00 h) eating, drinking, ruminating, standing, resting, locomotor and other behaviors were recorded. The frequencies of eating, drinking, ruminating, standing, resting, locomotor and other behaviors for bedding and nonbedding usage groups were 32.9 and 34.6% (p>0.05); 1.7, 2.6% (p<0.01); 20.3 and 20.5% (p>0.05); 20.5 and 28.4% (p<0.01); 14.8 and 7.9% (p<0.01); 8.5 and 4.4% (p<0.01) and 1.7 and 1.5% (p>0.05), respectively. The percentage of the eating behavior of cows of the bedding group at 9:00, 11:00, 13:00 and 17:00 observations were higher than the nonbedding group, while the other results at different observation hours show reverse results. As a result, the amount of time cows spend resting is higher in the bedding group, which is considered to significantly influence their comfort level. Resting behavior is an indicator of animal welfare and as such, this result suggests that bedding usage in loose housing systems provides a more comfortable and socially interactive environment that satisfies conditions of a more positive animal experience.

  The present study was carried out to investigate the effect of different type of calf hutches on growing performance and housing expenses of Holstein calves. Twenty five female calves born from February 2003 to April 2003 in Agricultural Faculty Farm, University of Cukurova, Adana, Turkey were used in the experiment. Birth weights for new material, Fiberglas and double layer tin-plate groups were 36.61±1.57, 36.44±1.19 and 34.81±1.70, respectively. The daily weight gain averages for the tint material, Fiberglas and double layer tin-plate groups were found 367.68±31.49, 319.22±27.69, 294.43±21.64 g d-1, respectively. The differences between the groups were not statistically significant (P<0.05) for calf hutches groups. All calves were kept together with their mothers for the first 3 days after calving and then were housed in individual pens in calf hutches. All calves were fed whole milk via pail twice a day according to the feeding programme, in which each calve received 245 litre feed during 10 weeks period in total. Calves were also received a commercial calf grower and alfalfa straw ad libitum from first week of the trial to the weaning. Fresh water were supplied to the calves ad libitum in pail after consuming their liquid feeds. The results obtained in the experiment showed that there were no differences in daily gain, conversion and weaning weight (P>0.01). New type hutch housing compared to fiberglas or double layer tin-plate groups in respect to calf performances but housing expenses was the lowest group for new material hutch type.
