“…Similarly to our observation, significant increase in serum TP was recorded in growing rabbits fed diets supplemented with 3 g/kg MOS (Ayyat et al 2018), in Japanese quail (Iqbal et al 2018) and broiler chicken (Hussein and Selim 2018). According to Paryad and Mahmoudi (2008), serum TP and ALB are directly responsive to protein intake and quality.…”

“…While the probiotic (B) was ineffective, MOS alone and in combination with the probiotic improved production traits. Results of efficacy of feed additives in rabbits are quite controversial (Bers enyi and Gippert 1995; Mourão et al 2006;Ayyat et al 2018). MOS supplementation in the diet, especially at 1.0 g/kg dose level, improved immunity, health indicators in the blood, live and carcass weight of rabbits (Abdel-Hamid and Farahat 2016).…”

Kovács (2019) Effect of feeding Bacilluscereus var. toyoi and/or mannan oligosaccharide (MOS) on blood clinical chemistry, oxidative stress, immune response and genotoxicity in T-2 toxin exposed rabbitsa Agr ar-es K€ ornyezettudom anyi Kar, Kaposv ar University, Kaposv ar, Hungary; b J arv anytani es Mikrobiol ogiai Tansz ek, University of Veterinary Medicine, Budapest, Hungary; c Mez} ogazdas ag-es K€ ornyezettudom anyi Kar, Szent Istv an University, G€ od€ oll} o, Hungary; d MTA-KE-SZIE Mikotoxinok az Elelmiszerl ancban Kutat ocsoport, Kaposv ar, Hungary ABSTRACTThe aim of the study was to determine the effect of Bacillus cereus var. toyoi (200 mg/kg) and mannan oligosaccharide (MOS, 2 g/kg) in T-2 toxin exposed rabbits. Weaned rabbits (35 days of age) were assigned into four experimental groups (n ¼ 20 in each): control (C), B. cereus (B), MOS (M) and B. cereusþMOS (BM) group. At 49 days of age, rabbits were divided into two groups (n ¼ 10 in each), and half of the C, B, M and BM rabbits were fed with the same diet as before, but contaminated with 2 mg/kg feed T-2 toxin (groups CT, BT, MT and BMT). On day 50 and 60, rabbits were injected with ovalbumin. At 70 days of age, all animals were sacrificed. Daily weight gain was smaller in toxin challenged animals (17.6-19.5 g) compared to controls (29.7 g). Serum total protein concentration was less in toxin treated animals, among them in CT group (49.7 g/L) it decreased underneath the reference range. T-2 increased the glutathione peroxidase activity in the kidney. C and B treatments resulted in the highest IgG production. Phagocytic activity was the lowest in CT animals (76.4%), while the highest in C and BM groups (82%). Cytokine expression in the intestinal mucosa was lower in T-2 exposed animals as compared to their relevant controls. None of the feed additives had any effect on the T-2 induced changes in the oxidative stress and immune response. T-2 had slight genotoxic effect on lymphocytes, which was alleviated by MOS and B. cereus. HIGHLIGHTSThe suspected protective effect of Bacillus cereus var. toyoi and mannan oligosaccharide was investigated in T-2 toxin exposed rabbits. T-2 impaired immune response and was slightly genotoxic on lymphocytes. MOS and B. cereus alleviated the genotoxicity of T-2. ARTICLE HISTORY

“…Uncontrolled conditions of heat stress can evoke multiple changes in animal biology and physiology (Ducray et al, 2016). In rabbit industry, heat stress is one of the important stressors affecting the productive performance, and usage of eco-friendly additives in the diet is essential for elimination of the harmful effects of heat stress on rabbit production (Ayyat et al, 2018). Therefore, the present study was conducted to evaluate the beneficial roles of curcumin and nano-curcumin, as natural feed additives on carcass traits, caecal activity and haematological parameters of growing rabbits reared under heat stress conditions.…”

“…Also, under heat stress conditions, oxygen-derived free radicals increased, creating oxidative stresses (Daader et al, 2018). In the rabbit industry, heat stress is an important stressor that affects productive performance, and the use of ecofriendly dietary additives to alleviate the negative impacts of heat stress remains a vital issue and increasing the rabbit production (Ayyat et al, 2018;Khalil et al, 2019). Supplementation of natural antioxidants from herbal sources as phytogenic, are accepted as a strategy for improving the utilization of nutrients, productive performance and health status of heat-stressed rabbits (Földešiová et al, 2015;Ojo and Adetoyi, 2017).…”

The present study investigated the effects of dietary curcumin or nano-curcumin on carcass traits, caecum activity, caecum microbial count and haematological parameters of growing rabbits reared under heat stress conditions. APRI line growing rabbits (n=100, 5-wk of age) were distributed to five equal groups (n=20/group). Rabbits in the 1 st group were fed a control diet without any additives, whereas 2 nd , 3 rd , 4 th and 5 th groups were fed control diet supplemented with curcumin (25 or 50 mg), and nano-curcumin (2.5 or 5 mg)/kg diet up to 13-wk of age. Carcass traits, meat chemical composition, pH values of gastro-intestinal tract contents, caecum activity, caecum microbial counts, and haematological parameters were determined at 13-wk of age. The mean temperature-humidity index during the experimental period was 29.54. Results showed curcumin or nano-curcumin levels increased (P<0.05) count of red blood cell and platelets, and caecum activity parameters (ammonia nitrogen and volatile fatty acids), while reduced (P<0.05) white blood cells, total microbial and E. coli counts in the caecal content. Haematocrit value increased (P<0.05) only by nano-curcumin groups (2.5 or 5 mg/kg diet). Carcass traits, chemical composition of meat and pH values of gastro-intestinal tract contents were not significant among groups. Dietary curcumin or nano-curcumin levels, as natural antioxidants and growth promoters, can alleviate adverse impacts due to heat stress on caecal activity and health status without affecting the carcass traits of growing rabbits. Generally, the dietary addition of curcumin in nano-particles form could contribute to produce healthy and high-quality rabbit's meat for human consumption.

“…Generally, Ayyat (2018) reported that feed additives may improve the dietary value in a dose-dependent manner and foster the production of rabbit meat, decrease the perirenal and scapular fat content and improve oxidative stability of rabbit meat.…”
