Waste management is the protection of the environment and the health of the population. Paper waste sludge is produced during paper production and sepiolite is a natural clay mineral. The aim of the study was to investigate the usability of sepiolite-added paper waste sludge as a bedding material in the broiler production. Two hundred eighty-eight 1-day old male broiler chicks were divided into the 6 bedding material groups (wood shavings (control), paper waste sludge, sepiolite, mix of 25% paper waste sludge and 75% sepiolite, mix of 50% paper waste sludge and 50% sepiolite, and mix of 75% paper waste sludge and 25% sepiolite) with 6 replicate pens per group. Litter quality, performance, and some welfare parameters of broilers were assessed during the 6 weeks’ period. Body weight at 42 days of age and body weight gain from 0 to 42 days of broilers reared on the wood shavings and mix of 50% paper waste sludge and 50% sepiolite were found higher than those of the sepiolite and paper waste sludge groups. Feed consumption and feed to gain ratio from 0 to 42 days, yields of carcass and carcass parts, percentages of organs and abdominal fat, IgG, percentage of bursa Fabricius, burns of foot pad and breast, litter pH and meat properties of broilers reared on the wood shavings, paper waste sludge, and sepiolite litter groups were not found to be statistically different. Litter moisture was found higher in the paper waste sludge group than that in the sepiolite group at the 42 days of rearing. As a conclusion, usage of mix of 50% paper waste sludge and 50% sepiolite as a litter does not have any negative effects on performance, welfare, and litter quality. This result is important in terms of utilizing a waste product.

The aim of the research was to determine the effects of red ginseng root powder on performance, immune system, caecal microbial population and some blood parameters in broilers. A total of 224 daily Ross 308 male broiler chicks were divided into one control group and three experimental groups each containing 56 chicks. Red ginseng root powder was added to the diets of groups at the level of 0, 75, 150 and 225 mg/kg, respectively. The experimental period was 38 days. There were no differences in growth performance. Addition of 225 mg/kg of the red ginseng root powder increased the relative weight percentages of spleen and gizzard (P

This study was proposed to examine the effects of pine needles powder (Pinus brutia) supplementation on growth performance, breast meat composition, and antioxidant status in broilers fed linseed oil-based diets. For this purpose, a total of 210, Ross-308 1-day-old male broiler chicks were allocated to 5 experimental groups each containing 42 birds. Broilers were fed a linseed oil-based basal diet supplemented with 0% (control), 0.25% (P1), 0.50% (P2), 0.75% (P3), and 1% (P4) pine needles powder. During the 42-D feeding period, no significant differences were observed between experimental groups for body weight gain, feed intake, and feed conversion ratio; however, carcass yield was increased linearly with pine needles powder supplementation. No marked changes in the breast meat chemical composition were observed among experimental groups. Supplemental pine needles powder linearly decreased the malondialdehyde concentration in breast meat and liver tissues; however, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of breast meat samples remained unaffected. No significant variation was observed among experimental groups for superoxide dismutase enzyme activity in blood erythrocyte lysates, but blood serum total oxidation status tended to decrease with pine needles powder supplementation. In conclusion, results suggested that pine needles powder supplementation to broiler diets could be a viable option to improve the animal antioxidant status and meat oxidative stability; however, supplementation of Pinus brutia needles powder up to 1% into broiler diets was not sufficient to efficiently curb the fat-induced oxidation in meat. Further investigation is needed to determine the full antioxidant potential of pine needles powder supplementation in poultry by comparing different pine species, evaluating the bioavailability of their active compounds and determining most effective dietary concentration for broiler meat production without any adverse effects.

The aim of the study was to explain the effects of betaine and sepiolite in diets on performance, carcass characteristics, some blood parameters and some intestinal health parameters in broilers. A total of 192 daily Ross 308 male broiler chicks were divided into one control group and three experiment groups each containing 48 chicks. Betaine and sepiolite was added as top dressed to the diets of experimental groups at the level of 0.15% betaine (1st group), 1.5% sepiolite (2nd group) and 0.15% betaine + 1.5% sepiolite (3rd group). Sepiolite and betaine were not added to the diet of control group. The experimental period was 6 weeks. No differences were observed in body weight, overall body weight gain, feed intake, feed conversion ratio, carcass yield and the relative weights of gizzard, heart, liver, spleen and bursa of Fabricius among groups. The relative weight of abdominal fat decreased with betaine usage. Supplemental betaine increased relative percentage of kidney weight. Dietary supplementation of betaine with sepiolite had some positive effects on intestinal histomorphology characteristics. The level of serum triglyceride was reduced with 0.15% betaine inclusion in the diet. Albumin, cholesterol, protein, uric acid, AST, ALP and ALT levels of blood serum were not affected by betaine with and without sepiolite supplement. Blood serum IgG level was increased by dietary supplementation of betaine with and without sepiolite. It is concluded that the dietary usage of betaine with sepiolite in broilers can be useful in the field due to having some improvements in intestinal histomorphology and immunity.

This study evaluated the effects of a graded concentration of dietary calcium soaps of tallow (CST) supplementation on broiler performance, carcass characteristics, abdominal fat fatty acid profile, bone biomechanical properties, and bone mineral composition. One hundred and forty 11-d-old male broiler chickens were randomly allocated to 4 experimental groups with 5 replicate pens containing 7 birds per each. The birds received cornsoybean meal based diet and CST (CST0, CST10, CST20, and CST30, respectively) was included in the grower (0, 10, 20, and 30 g/kg) and finisher (0, 15, 30, and 45 g/kg) diet at the expense of vegetable acid oil and limestone. Dietary supplementations had no significant effect on BWG and FI during the entire experimental period. However, FCR was improved in CST0 and CST10 groups in comparison to those of the CST20 group from d 11 to d 42. According to the present study result, dietary supplementation of low level of CST significantly influenced intestinal microarchitecture of the jejunum and ileum by improving villus height/crypt ratio and villus height, respectively. Femur (P=0.001) and tibia (P=0.020) stiffness increased linearly with the increasing level of dietary CST. Tibia Ca (P=0.009) and P (P=0.009) concentration of CST10 and CST30 groups were lower than the CST0 group. Increasing levels of CST in diets significantly reduced the Fe and Mn concentrations in tibia samples. In conclusion, supplementation of CST has no detrimental effect on broiler performance parameters and might be used as an alternative dietary fat source in the broiler industry.

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.
