  This study was conducted on 46 Redkaraman lambs born at the Ataturk University, Agricultural Faculty Sheep Research Farm. The lambs were weaned at different ages such as 45, 60 and 75 days. After weaning, the lambs were sent to the pasture and fed on concentrate including 15.3% crude protein in a ratio of 1.5% of live body weight for the first 6 weeks thereafter, amount of feed was increased to 2% of the live body weight in addition to pasture at the evenings. Live body weights and daily weight gaing of lambs were determined from 45 days to end of the grazing period within 14 days intervals. Live weights at 45 days for the lambs weaned at 45, 60 and 75 days were 12.20, 11.58 and 12.47 kg and at 60 days were 14.38, 14.79 and 15.40 kg and 75 days were 15.30, 16.06 and 17.28 kg. Live weights at the end of the grazing period were 34.86, 35.11 and 38.93 kg for the lambs weaned at 45, 60 and 75 days of age, respectively. The differences among the group were found significant (p<0.05) for live weights at the end of the grazing period. Daily weight gains of lambs in the groups were found as 144.5, 145.7 and 164.0 g for the end of the grazing period; 137.3, 142.6 and 160.5 g for the 46 days of age and 136.5, 135.5 and 157.0 g for 61 days of age. The differences among the group were found significant (p<0.05). The results of this research indicated that there were significant (p<0.05) differences for the live weights at the end of the grazing period in Redkaraman lambs weaned at various ages, also there were significant (p<0.05) differences for daily weight gains at the end of the grazing period, 46 and 61 days of age.

  This study aimed to investigate the effect of various ages (45, 60 and 75 days) of weaning on growth, survival rate and some body characteristics in Awassi lambs. Following weaning, the lambs were separated from their dams and taken to the pasture and were fed with concentrate including 15.3% crude protein in the evenings in addition to the pasture. The live weights and daily weight gains of the lambs were determined by weighing at 14 days intervals starting from day 45 till the end of pasture. Five females from each group were used in the determination of body measurements. In the study, in the lambs weaned at the age of 45 (group I), 60 (group II) and 75 (group III) days old; birth weight and live weights on days 45, 60, 75, 120 and 210 (end of pasture) were calculated on average as 4.58, 11.58, 13.95, 15.95, 21.54 and 34.44 kg, respectively and in the significance checks performed, it was identified that there was no significant (p<0.05) difference between the groups except for the day 210 live weight. There was not any difference observed between the groups in terms of Daily Live Weight Gain (DLWG). It was identified that the effect of the age of dam on live weight in lambs was insignificant in all periods that the effect of type of birth was very significant (p<0.05) except for the day 120 live weight and that the effect of sex was significant (p<0.05) in birth, day 60, 75 and 210 weights and very significant (p<0.01) in day 120 live weight. On looking at the survival rate characteristics, it was observed that this was lower in the group weaned at 45 days old on days 120 and 210 at a statistically significant (p<0.05) level compared to the other two groups. Furthermore, it was identified that singletons exhibited a higher survival rate at a statistically very significant (p<0.01) level compared to twins. The effect of weaning at various ages on the body measurements was found to be insignificant except for the chest width measured on day 210. Consequently, it may be said that taking into consideration the live weight gains and survival rate characteristics of Awassi lambs, the most suitable weaning age may be arranged as 60 days old.

  The objective of this study was to evaluate the effect of Saccharomyces cerevisiae (SC) on milk yield, milk compositions and the body condition score raised organically in dairy cattle. For this aim, 120 lactating Holstein Friesian dairy cows were randomly divided into group control (n = 60) and treatment (n = 60) in a private organic dairy farming in the Kelkit District of the Gumushane Province in Turkey. The diet of group treatment each cow was supplementation with 6 g SC per day. The experimental was started after 30 days of calving and lasted 45 days after. The average daily milk yield production (p<0.01) was higher in the SC group (34.6±0.31 vs. 31.8±0.44 kg day-1 in the treated and control group, respectively). The effect of SC on some milk compositions as non-fat solids (%), milk fat (%), protein (%) and lactose were statistically non-significant. Body condition score in the treated group (2.74±0.016) was higher than control group (2.58±0.017) (p<0.01). It was concluded that milk yield capacities in organic dairy cattle farming in case that the similar results are confirmed with additional studies can be substantially increased.
