    This study investigated the role of phytogenic supplements on the reproductive physiology and metabolic hor mones of rabbits exposed to heat stress conditions. Fresh Moringa oleifera, Phyllanthus amarus and Viscum album leaves were obtained and processed into a leaf meal using standard procedure and served as a phytogenic supplements. Eighty rabbit bucks of 6 weeks old (514.84 ± 14.10 g) were randomly assigned to the four dietary groups consisting of Diet 1 without the leaf meal (control diet) and Diets 2 (D2); 3 (D3) and 4 (D4) contained 10% Moringa, 10% Phyllanthus and 10% Mistletoe, respectively, in an 84-day feed trial at the peak of thermal discomfort. Semen kinetics and seminal oxidative status, reproductive and metabolic hormones were assessed using standard procedure. Results reveal that sperm concentration and motility traits of bucks on D2, D3 and D4 were significantly (p < 0.05) higher than bucks on D1. Spermatozoa speed traits of bucks on D4 were signifi cantly (p < 0.05) higher than bucks on other treatments. Seminal lipid peroxidation of bucks in D2-D4 was significantly (p < 0.05) lower than bucks on D1. Corticosterone of bucks on D1 was significantly higher than bucks on other treatments (D2-D4). Lutenizing hormone of bucks on D2 and testosterone of bucks on D3 was higher (p < 0.05) than in other groups, while follicle stimulating hormone of bucks on D2 and D3 were higher (p < 0.05) than bucks on D1 and D4. In conclusion, the three phytogenic supplements improved sex hormones, enhanced spermatozoa kinetics, viability and seminal oxidative stability of bucks during heat stress condition

    HSP70, adiponectin, leptin, pro-inflammatory cytokines and metabolic hormones of heat-stressed broilers fed herbal supplements

    Global warming undoubtedly is a serious challenge facing poultry production especially in tropical climate, which subject animals to heat-stressed conditions leading to multiple physiological alterations. An investigation was conducted to determine the role of herbal supplements on adipokines, pro-inflammatory cytokines and metabolic hormones of broilers exposed to heat stress. 200 a day-old broiler chicks were randomly allotted to standard diets; diet 1 without leaf meal (T1), diet 2 with 5% Moringa oleifera (T2), diet 3 with 5% Phyllanthus amarus (T3) and diet 4 with 5% mistletoe; Viscum album (T4) in a 49-day feed trial during the peak of thermal discomfort in Southern Nigeria, to assess hormones, adipokines and cytokines using standard procedures. Results obtained shows that triiodothyronine of birds fed phyllanthus and mistletoe were significantly (p < 0.05) higher than birds on basal diet. Corticosterone of birds fed mistletoe and phyllanthus were significantly (p < 0.05) lower than those obtained in birds on basal diet. Heat shock protein of birds fed on moringa supplements were significantly (p < 0.05) lower than those in birds on basal diet. The adiponectin of birds fed on basal diet were statistically (p < 0.05) higher than other treatments. Interleukin 6 of birds on phyllanthus and mistletoe sup plements were not significantly (p > 0.05) different from birds on basal diet. Interleukin 1β of birds fed basal diet was significantly (p < 0.05) higher than birds fed moringa supplements and the significantly (p < 0.05) least values obtained in those of birds fed phyllanthus supplement. Tumor necrosis factor α of birds fed on phyllanthus and mistletoe were significantly (p < 0.05) higher than birds fed basal diet and the significantly (p < 0.05) least values were obtained in birds fed moringa supplement. In conclusion, three herbal supplements decreased the HSP 70, leptin and adiponectin of broilers exposed to heat stress and moringa supplements lower pro inflammatory cytokine expression in heat stress birds.

    Performance, hemato-biochemical indices and oxidative stress markers of broiler chicken fed phytogenic during heat stress condition
    (Korean Society of Animal Science and Technology, 2022) Olatunji Abubakar Jimoh; Olajumoke Temidayo Daramola; Hafsat Ololade Okin-Aminu; Olayinka Abosede Ojo
    Thermal stress is a tremendous health predicament encountered by poultry farmers with adverse effects on the performance, product stature, health condition, survival, and overall welfare of poultry birds, and so requires urgent dietary user-friendly strategy to curb. This study was conducted with 200-day old broilers for the purpose of investigating the potential of phytogenics in refining the negative effects of heat stress on broiler chicken. Moringa, Phyllanthus and mistletoe leaves were processed as phytogenic supplements and incorpo rated into standard ration for broilers as treatments B1 (control), B2, B3 and B4 diet during the peak of thermal discomfort in humid tropics. Growth and carcass indices were monitored in a 49-day trial and blood samples were harvested at the end of the ordeal period to assess haematology, serum biochemical and oxidative stress markers with the use of standard pro cedures. The results obtained showed that the prevailing environmental condition in the study site indicated that the birds were exposed to heat stress. Birds fed on moringa and mistletoe supplements had higher performance index than birds without supplementation during heat stress condition, while birds fed on mistletoe supplement had the highest survival rate across the treatments. The liveweight, slaughter weight, dressed weight and eviscerated weight of heat stressed birds fed on moringa, phyllanthus and mistletoe supplements were significantly higher than birds on control treatment. Heterophyl/lymphocyte ratio of heat stressed birds without supplement were higher than birds on phytogenic supplements, with least values recorded in phyllanthus and mistletoe fed birds. Birds on phytogenic supplement tend to have lower cholesterol profile, lipid peroxidation and better antioxidant profile than birds on control treatment during heat stress conditions. Mistletoe supplementation in broiler ration enhances the survival rate, as well as promotes growth indices better among the phytogenic supplements. However, phytogenic supplements did ameliorate the negative effects of thermal discomfort on performance, physiological and oxidative stress in heat-stressed broiler chicken.
