The animal material of the study consisted of native Turkish geese. Regardless of the sex of the chicks, the first 4 wk of age were fed together, and the 5 and 6 week of age were fed ad libitum in groups using the starter feed. From the sixth wk onwards, four fattening method were formed until the 16 week of age as feed, pasture + cracked barley, pasture + feed and pasture. In the feed, pasture + cracked barley, pasture + feed groups, general body weight increase averages are 39.81, 37.46 and 39.90 g, respectively; average feed daily consumption is 426.95, 207.99 and 200.76 g, respectively; feed conversion ratio were 10.72, 5.55 and 5.03, respectively. At the end of the study, body weights were determined as 4209, 4108, 4239 and 3971 g in the feed, pasture + cracked barley, pasture + feed groups and pasture groups, respectively (P

This study investigated the impact of an essential oil (EO) mixture (Biomin) on growth performance, carcass yield, visceral organ weights, and duodenal crypt depth in native Turkish geese (Anser anser). Sixty 1-day-old goslings constituted the animal material of the trial. Goslings were divided into three treatment groups, each consisting of four subgroups having five animals each. Animals were homogenously distributed among the groups after being weighed and identified. The three treatment groups received the essential oil mixture at rates of 0.0% (without EO), 0.1% and 0.2%, respectively. The animals were given concentrate feed (21.93% CP and 3010 kcal/kg ME) for the first 2 weeks, and were both grazed and provided with barley meal for the next 8 weeks. The trial was continued for a period of 10 weeks. Results showed that the essential oil mixture had no significant effect on live weight gain, feed intake, feed conversion rate, carcass yield, and heart-liver-gizzard weights (P>0.05). On the other hand, the crypt depths of the EO 0.1% and EO 0.2% groups were greater than that of the EO 0.0% group (P
