Öğe Effect of early weaning at different weaning weights on growth and feed efficiency characteristics of the Brown Swiss and Holstein Friesian calves(Indian Counc Agricultural Res, 2003) Ugur, FBrown-Swiss and Holstein - Friesian calves weaned at 45 days age were separated into 2 groups (32-45 and 46-61 kg) based on their weights on 45 days age. The effect of the weight groups at 4 - months old calves were significant, but, the average weights gain in the periods between birth and 6 months and feed efficiency were insignificant. The correlation between 2 weight groups at weaning and sixth months weight and between weight groups at weaning and daily weight gains between weaning and 6 month of ages were nonsignificant.Öğe Effect of the different weaning ages on the growth and feed conversion efficiencies in Holstein-Friesian calves(Indian Counc Agricultural Res, 1998) Ugur, F; Yanar, M[Anstract Not Available]Öğe Growth and behavioral traits of Turkish Saanen kids weaned at 45 and 60 days(Elsevier Science Bv, 2004) Ugur, F; Savas, T; Dosay, M; Karabayir, A; Atasoglu, CThe influence of weaning age on various growth characteristics and behavioral traits of Turkish Saanen kids was investigated. The kids were weaned at 45 and 60 days of age. The body weights, body measurements and behavioral traits were monitored during the experimental period. The average daily live weight gains of the kids in both of the treatment groups were similar between weaning and 4 months of age, and birth and 4 months of age. Weaning age influenced roughage and water consumption, and lying. Although there were no difference between the two groups in terms of growth characteristics, kids in 45-day group consumed more roughage than those in 60-day group. Because of a 15-day difference between the two weaning practices, the kids, weaned at 45 days of age seemed more experienced and spent the rest of their spare time lying. The results of the present study indicated that no significant differences were found in the growth and behavioral traits of Turkish Saanen kids, weaned at 45 or 60 days of age, and suggested that kids could be weaned at 45 days of age.

Data included 884 records collected from 61 Turkish Saanen kids raised in Canakkale, Turkey. Slopes were calculated for each kid and were analyzed as data using ordinary least squares, and repeated weights for each kid were analyzed using various covariance structures. Differences between male and female kids were small and non-significant before weaning (P = 0.55), while larger (P=0.06) after weaning. Heavy animals grew faster than light animals before weaning (P < 0.01) but lost their advantage after weaning (P > 0.05). Fat animals (high BMI) grew faster than lean animals (low BMI) before weaning (P < 0.01) while the differences slightly diminished after weaning (P=0.04). This may be because light and lean kids were not affected from the weaning shock as much as the heavy and fat kids, which had stuttered growth after weaning. Fit statistics indicated that first-order ante dependence was the best fit covariance structure for these data. Analyses specifying random model and covariance structures did not have an advantage over an approach where slopes were manually calculated and analyzed as data using ordinary least squares.Öğe Performance of calves fed a limited amount of milk in Eastern Anatolia conditions(Cuban Journal Agr Sci, 2004) Ugur, F; Özhan, M; Yanar, M; Tüzemen, NThe purpose of this research was to study the possibility of reducing weaning age in dairy calves, Brown Swiss calves were weaned at 30, 45 and 60 d of age. In the milk feeding period, the amount of daily milk given to calves in the groups was kept constant at 7 % of their birth weight. The body weight of 4-month calves fed milk for 30, 45 and 60 d were 82.6 +/- 2.0, 85.2 +/- 2.0 and 79.1 +/- 2.0 kg, respectively. The body weight of 6-month calves weaned at 30, 45 and 60 d of age were 127.8 +/- 2.9, 133.2 +/- 2.9 and 127.2 +/- 2.7 kg, respectively. The average weight gains determined between birth and six months of age for the calves weaned at 30, 45 and 60 d of age were 0.51 +/- 0.01, 0.55 +/- 0.01 and 0.52 +/- 0.01 kg, respectively. The differences among the groups were found to be non-significant. The effect of weaning age was non-significant for the total dry matter of feed consumed per kilogram of weight gain. The results of this study suggested that Brown Swiss calves could be weaned at 30 d of age without having any adverse effect oil their growth and feed conversion efficiency.
