“…We observed that dietary supplementation of 120 and 240 mg/kg EO significantly increased the serum NDV antibody titers compared with the basal diet or diet with 60 mg/kg EO in the challenged birds. This was consistent with previous studies, which demonstrated that dietary supplementation of EO enhanced the specific immune responses in broilers and laying hens [ 14 , 46 , 47 ]. As the most abundant immunoglobulin isotype in mucosal secretions, sIgA is the fundamental effector to mucosal immunity.…”

BackgroundNecrotic enteritis caused by Clostridium perfringens infection leads to serious economic losses in the global poultry production. In the present study, we investigated the protective effects of essential oils (EO, which contained 25 % thymol and 25 % carvacrol as active components) supplementation on growth performance, gut lesions, intestinal morphology, and immune responses of the broiler chickens infected with C. perfringens. A total of 448 1-day-old male broiler chicks were allocated into eight treatment groups following a 4 × 2 factorial arrangement with four dietary EO dosages (0, 60, 120, or 240 mg/kg) and two infection status (with or without C. perfringens challenge from d 14 to 20).ResultsThe challenge did not impair the growth performance of birds, but induced gut lesions and increased crypt depth in the ileum (P ≤ 0.05). It also down-regulated the claudin-1 and occludin mRNA expression (P ≤ 0.05), up-regulated the mRNA expression of interleukin-1β (P ≤ 0.05), tended to increase the toll-like receptor (TLR) 2 mRNA expression (P < 0.10) in the ileum, and enhanced the mucosal secretory IgA production (P ≤ 0.05). In the challenged birds, dietary EO supplementation linearly alleviated the gut lesions and improved the ratio of villus height to crypt depth (P ≤ 0.05), and the supplementation of 120 and 240 mg/kg EO increased the serum antibody titers against Newcastle disease virus (P ≤ 0.05). Regardless of challenge, the EO supplementation showed a tendency to linearly elevate the feed conversion efficiency between 14 and 28 d of age as well as the occludin mRNA expression (P < 0.10), and linearly inhibited the mRNA expression of TLR2 and tumor necrotic factor-α in the ileum (P ≤ 0.05).ConclusionsThe dietary supplementation of EO could alleviate the intestinal injury by improving intestinal integrity and modulating immune responses in the C. perfringens-challenged broiler chickens.

“…Mycosorbents are able to bind aflatoxin molecules in the gastrointestinal tract and thus, to reduce their absorption by domestic fowl. The results agree with data from other studies with mycosorbents as clinoptiolite (Oguz et al, 2003), hydrated calcium aluminosilicate (HSCAS), sodium bentonite, montmorillonite (Ologhobo et al, 2015), essential oils (Saei et al, 2013), antioxidants (resveratrol) (Sridhar et al, 2015) and probiotics (Zuo et al, 2013).…”

“…Reduced feed utilisation is also a result from the decreased activity of a number of enzymes involved in carbohydrate, proteins, nucleic acids conversion, to reduced intake or nutritional deficiency (Makinia, 2014). On the other hand, the lower feed intake is attributed to increased blood ammonia concentrations following reduced glomerular filtration rate (Saei et al, 2013). The lower weight gain is due to reduced protein synthesis rate, impaired lipogenesis, reduced protein and lipid utilisation from feeds, enhanced faecal excretion of lipids.…”

The contamination of poultry feeds with aflatoxins is a global problem responsible for considerable losses to poultry industry. The aim of the present investigation was to evaluate the effects of aflatoxin B 1 and Mycotox NG, applied either independently or together, on performance, relative weights of visceral organs and antibody titres against Newcastle disease in turkey broilers. Experiments of 42-day duration were carried out with sixty 7-day-old female turkey broilers (meat TM strain) divided into one control and five treatment groups (n=10): Group І -control (fed standard feed according to the species and age of birds); Group II -experimental, whose feed was supplemented with 0.5 g/kg Mycotox NG, Group ІІI -experimental, whose feed contained 0.2 mg/kg aflatoxin В 1 , Group IVexperimental, whose feed contained 0.4 mg/kg aflatoxin В 1 , Group V -experimental, supplemented with 0.2 mg/kg aflatoxin В 1 and 0.5 g/kg Mycotox NG and Group VI -experimental, supplemented with 0.4 mg/kg aflatoxin В 1 and 0.5 g/kg Mycotox NG. In Groups III and IV, production traits (live body weight, daily weight gain, feed intake) as well as antibody titres were reduced along with increased feed conversion and relative weights of liver, kidneys, heart, pancreas, proventriculus and gizzard. At the same time, relative weights of the spleen, thymus and bursa of Fabricius were statistically significantly lower. The supplementation of the feed of Groups V and VI with 0.5 g/kg Mycotox NG reduced and prevented some of deleterious effects of AFB 1 on production traits, antibody titres and relative weights of visceral organs.

“…In addition, especially on the 33rd day of the study, it was determined that the body weight value of the quails in the M and MLPS groups was significantly lower than the control and LPS group quails (P<0.05). However, it was reported that the addition of murt oil to Japanese quail feed (1000 mg/kg/day, Biricik et al 2012) and broiler feed (500 mg/kg, Sadeghi et al 2013;Goudarzi et al 2016) had a positive effect as a potential growth promoter. Animal performance characteristics and the dose difference of the herbal antioxidant added to the basal diet can be expressed as an important reason for the differences in the study results.…”

This study, it was aimed to determine the effects of murt volatile oil added to the diet on Lipopolysaccharide (LPS) induced inflammation on body weight, feed consumption, feed conversion ratio, slaughter characteristics, some blood and organ parameters in quails. The study groups were formed as follows: control (commercial chick starter feed), M group (commercial chick starter + 200 mg/kg Murt volatile oil), MLPS group (commercial chick starter + 1 mg/kg-17th day and 7.5 mg/kg- 24th day intrabdominal LPS administered group) and LPS (commercial chick starter feed + 1 mg/kg 17th day and 7.5 mg/kg - 24th day intraabdominal LPS administered group). The study, 4 experimental groups consisting of 40 (4x10) quail chicks were formed and the fattening period lasted for 36 days. The study, blood and liver OSI (Oxidative stress index) values were found to be lower in the M and MLPS groups with murt supplementation than in the control groups without murt addition. During the study, the body weight value was determined lower in the groups with Murt added than in the groups without Murt addition. In addition, the feed conversion ratio was significantly better in the M group with murt supplementation between the 5th and 33rd days than in the other groups. Significant differences were determined between the groups in terms of gizzard ratio and chest+back+neck+wing ratio values. In the study, macroscopic and histopathological hyperemia was not observed in the small intestines, there was an increase in cell infiltration in other groups with added murt compared to the control group, and degeneration and necrosis of the epithelium were detected more prominently. In the study, it was determined that the addition of murt to quail compound feed had a positive effect on growth performance, feed consumption and feed efficiency.
