The aim of this study was to investigate the effects of resveratrol extract (RE) and curcumin extract (CE) added to diet on the serum biochemical parameters and hepatic enzyme levels as Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Gamma Glutamyl Transferase (GGT) of broiler. A total number of 200, 0-day-old male broiler chicks (Ross 308) were used in the study. The animals were divided into 5 groups; the control group was fed only basal diet but groups RE-1, RE-2, CE-1 and CE-2 had 250 mg/kg RE, 500 mg/kg RE, 250 mg/kg CE and 500 mg/kg CE, respectively, added to their diets. At the end of the study, 10 randomly selected animals from each group were slaughtered and blood was taken from the vena jugularis and used in the analysis. In the examinations, it was determined that the serum creatinine level in the group RE-1 and the Lactate Dehydrogenase (LDH) level increased significantly in the group CE-2 group. In addition, it was determined that the albumin/globulin ratio in the RE-2 group, and the magnesium (Mg) level increased significantly in the RE-1 and RE-2 groups. It was found to be statistically similar in all groups that serum glucose, cholesterol, triglyceride, urea, blood urea nitrogen (BUN), creatine kinase (CK), ALT, AST, ALP, GGT, amylase, total protein, albumin, globulin, calcium (Ca) and phosphorus (P) levels. As a result, it was observed that the additives applied did not have an effect on serum hepatic enzymes and partially affected other routine biochemical parameters.

Bu çalışma, etlik piliç rasyonuna ilave edilen fukoksantinin serumda lipid profili ve bazı metabolik parametreler üzerine etkisini belirlemek amacıyla yapılmıştır. Çalışmada toplam 180 adet günlük erkek civciv (Ross 308) kullanılmıştır. Deneme 42 gün sürdürülmüştür. Gruplandırma Kontrol (K), F1 ve F2 grupları şeklinde yapılmıştır ve gruplara bazal rasyona ilave olarak sırasıyla 0, 100 ve 200 mg/kg rasyon fukoksantin katılmıştır. Biyokimyasal analizler çalışmanın sonunda (43. gününde) her gruptan 10 adet hayvandan alınan serum numunelerinde yapılmıştır. Fukoksantin uygulamasının sadece F2 grubunda serum trigliserit (TG) seviyesini arttırdığı, total kolesterol (TK), yüksek yoğunluklu lipoprotein kolesterol (HDL-K) ve düşük yoğunluklu lipoprotein kolesterol (LDL-K) seviyelerini etkilemediği tespit edilmiştir. Serum glikoz, kalsiyum, fosfor ve magnezyum seviyelerinin tüm gruplarda benzer olduğu belirlenmiştir. F2 grubunun total protein ve albümin seviyeleri K grubuna benzer olurken F1 grubuna göre önemli düzeyde azaldığı tespit edilmiştir. Ayrıca F2 grubunun ürik asit seviyesinin K grubuna göre önemli düzeyde azaldığı belirlenmiştir. Sonuç olarak fukoksantinin serum parametrelerini sınırlı düzeyde etkilediği görülmüştür.

The poultry industry in the developing countries is facing some challenges, one of which is an increase in the cost of feed because of high prices of protein and energy sources. Moringa oleifera is a rich source of protein and crude fiber content. The crude protein (CP) content of Moringa ranges from 7.12 to 39.17%. Negligible content of tannins and other anti-nutritive compounds and offers an alternative source of protein to ruminants and non-ruminants. Although rich in nutrients such as protein and minerals, Moringa oleifera is one of those plants that have not been studied for many years. In addition, they are also faced with the problem of the development of antibiotic resistant pathogens due to unwise and excessive use of antibiotics. In this paper, feeding studies made on the Moringa oleifera used in nutrition of poultry and ruminant species have been reviewed.

Leg problems have caused significant economic losses in poultry sector. Bone quality and strong is related to nutrition. In this review, effects of nutrition on bone strength are given to laying hens and broilers. For this, effects of some minerals and feed additives on bone quality were reviewed. Calcium, phosphorus, boron and some feed additives in feeding of hens and broilers are important to strong bone. In addition, the form of calcium resources must be considered in laying hens.
