The aim of the present study was to investigate the usage of thyme leaves and its effects on performance, some egg quality traits and humoral immunity in laying hens. A total of 108 laying hens aged 36 weeks were randomly assigned to three dietary groups for 16 weeks. Dried and ground (Thymus vulgaris L.) thyme leaves were used at the level of 0, 1 and 2% in the diets of groups. Feed intake, body weight, egg production, egg weight and egg quality characteristics were not affected by dietary thyme supplementation. Thyme supplementation at 2% resulted in beneficial effects in laying hens due to the lowering of yolk cholesterol and total saturated fatty acids concentration while increasing omega-3 fatty acids. Furthermore, the yolk malondialdehyde, blood serum cholesterol and triglycerides levels were reduced and antibody titers against SRBC were increased with 2% thyme supplementation. In conclusion, the results showed the antioxidative and hypolipidemic effects of thyme supplementation in laying hens along with improved humoral immune response without any negative effects on performance and egg quality characteristics.

Bu araştırma, yumurta tavuğu rasyonlarına sepiyolit ilavesinin 22 hafta süreyle performans, yumurta kalitesi ve bazı kan parametreleri üzerine etkilerini belirlemek amacıyla yapılmıştır. Bu amaçla 38 haftalık yaşta 135 adet Lohmann Brown yumurta tavuğu 1 kontrol ve 2 deneme grubuna ayrılmıştır. Sepiyolit kontrol, birinci ve ikinci deneme gruplarının rasyonlarında sırasıyla % 0, 0.5 ve 1 olacak şekilde ilave edilmiştir. Sepiyolit ilavesi yem tüketimi, yumurta verimi, yumurta ağırlığı ve yemden yararlanmayı etkilememiştir. Rasyonlarda %1 düzeyinde sepiyolit kullanılmasıyla yumurta kırılma mukavemeti (p

WOS: 000342266000009, The objective of this study was to determine the effects of dietary yeast cell wall (YCW) on performance, egg quality, some blood parameters and humoral immune response of laying hens during 26 wks period. For this purpose a total of 225 Hyline Brown laying hens, 39 wks of age, were allocated to one control group and four treatment groups. Basal diet was supplemented with YCW derived from bakers yeast Saccharomyces cerevisiae (InteMOS) at the level of 1, 2, 3 and 4 g/kg in the diets of the first, second, third and fourth treatment groups, respectively. Dietary treatments did not significantly affect body weight, feed intake, egg production, egg weight, feed conversion, and egg internal and external quality characteristics. YCW supplementation at the level of 1 and 2 g/kg decreased egg yolk cholesterol level as mg per g yolk (P < 0.05). Blood serum levels of cholesterol and triglyceride were decreased with the dietary inclusion of YCW at the level of 2, 3 and 4 g/kg (P < 0.01). Dietary YCW supplementation increased antibody titres to SRBC (P < 0.01). As a result dietary YCW at the level of 1 and 2 g/kg had beneficial effects in the production of low cholesterol eggs and improvement in humoral immunity response., Integro Food and Feed Manufacturing Company (Istanbul, Turkey), This work was supported by Integro Food and Feed Manufacturing Company (Istanbul, Turkey).

WOS: 000344689400018, This study was carried out to determine the effects of dietary yeast cell wall supplementation on growth performance, carcass traits, antibody production to sheep red blood cells (SRBC) and histopathological changes in broilers. A total of 272 Ross 308 male broiler chicks aged one day were allocated into one control group and three treatment groups each containing 68 chicks. A basal diet was supplemented with 0, 1, 2 and 3 g/kg yeast cell wall (InteMos) to obtain dietary treatments. The experimental period lasted 6 weeks. Dietary yeast cell wall increased body weight gain during the first three weeks (P, Integro Food and Feed Manufacturing Company (Istanbul, Turkey), The authors wish to thank Integro Food and Feed Manufacturing Company (Istanbul, Turkey) for supporting this study and Beypilic for supplying chicks (Bolu, Turkey).

This study was carried out to determine the effects of dietary sepiolite on performance, carcass traits and some blood parameters of broilers. A total of 204 daily Ross 308 female broiler chicks were allocated into one control group and two treatment groups each containing 68 chicks. Sepiolite was used at the level of 0%, 0.5% and 1% for the diets of control group and the first and second treatment groups, respectively. The experimental period lasted 6 weeks. Supplemental sepiolite improved body weight (P
