    Effect of nano-encapsulated ginger on the physiological response, oxidative status and hormonal profile of rabbits reared in the tropics
    (Elsevier, 2023) O.A. Ojo
    The nano-encapsulation technology of phytogenic bio-components is a new technology employed to solve the unstability challenge associated with phytonutrients, when used as a phytogenic component generally and in animal studies. Incidence of global warming have resulted into heat stress, adversely affecting animal health and performance. Application of phytogenic bioactive components, such as the ones found in ginger has proven positive, this is because ginger (Zingiber officinale Roscoe) contains gingerols, specifically 6- gingerol, which is an active compound, noted to contain strong antioxidant activity. However, the instability of phytonutrients in the gut necessitated adoption of nanotechnology, incorporated into phytochemistry to ameliorate heat stress and improve animal performance. This research was conducted to evaluate the effectiveness of nano-encapsulated ethanolic ginger extract on the physiological response, oxidative status and hormones of rabbit does in the tropics. Sixty-four nulliparous (7-months-old) pure line breeders (New Zealand White Rabbit does), averagely weighing 23kg, aged between four to six (4–6) months were used. Experimental does were randomly allocated to four treatment groups at 16 does per treatment. Experimental design is as follows; Group 1 received 3mls of water, Group 2 - 50mg/kg body weight of non encapsulated ginger extract in 3mls of water. Group 3- 10mg/kg body weight of nano-encapsulated ginger extract in 3mls of water. Group 4- 25mg/kg body weight of nano-encapsulated ginger extract in 3mls of water. Blood was collected via marginal ear vein, serum separated through centrifugation. triodothyronine, tetraiodothyronine and luteinizing hormone were analyzed using commercial solid-phase enzyme immuno-assay kits. It was noted that at week 4, respiratory rate, ear temperature, heart rate and rectal temperature (100.25±1.47, 100.44±1.45, 24.66±1.30, and 24.76±1.37) were significantly (P<0.05) lowered in treatment group 4, administered with 25mg/kg nano-encapsulated ginger, in comparison to other treatment groups. All oxidative parameters evaluated were not significantly influenced by the experimental supplementation of nano-encapsulated ginger. However, 10mg/kg body weight of nano-encapsulated ginger administration lmproved the luteinizing hormone concentration of test animals under treatment group 3

    ABSTRACT Background: Japanese quails have the potentials of being cheap source of animal protein. This study was conducted to determine the growth pattern and physiological response of Japanese quails to administration of aqueous solution of egg lime molasses mixture (ELM). Methods: ELM was prepared by placing fresh eggs in a bowl after which 1 liter of lime juice and 500 g of molasses were added and left for 10 days at temperature of 27C and relative humidity of 61%. The entire solution was then blended together. Two hundred day old Japanese quails were assigned to five treatments (4 replicates/treatment) with forty birds in a completely randomized design (CRD). The control (T1) having no administration of ELM, T2 had an inclusion level of 10 ml, T3: 20 ml, T4: 30 ml and T5: 40 ml ELM all into 500 ml of water. Feed and water were offered ad libitum. The study was carried out for 49 days. Data were collected on growth, morphometrics and key physiology parameters. Data were subjected to descriptive statistics and Analysis of Variance using SPSS Version 22. Result: Significant difference (p<0.05) was observed only for feed conversion ratio at the starter phase, however, birds administered 20 ml ELM/500 ml of water had the best FCR. Significant differences (p<0.05) were observed for live weight and weight gain at the finisher phase. Significant differences (p<0.05) were observed in body morphometrics with birds administered 20 ml/500 ml of water having the highest values. There were significant differences (p<0.05) in rectal temperature and respiratory rate at the starter phase while at the finisher phase, significant difference (p<0.05) was only observed in rectal temperature. It can be concluded from this study that aqueous administration of egg lime molasses solution in the diet of Japanese quails has no detrimental effect on the growth pattern and physiological response.

    Lycopene and African walnut extract improved seminal antioxidative enzymes and serum biochemical Indices of heat-stressed cockerels
    (Elsevier, 2025) O.A. Ojo; K. Okukpe; O.A. Jimoh; A.O. Akintunde; U.U. Carols
    Herbal supplementation during climatic stress could alleviate neuronal cell damage, prevent tissue retention of synthetic pharmaceuticals and enhance better health status of animal product consumers. Incidence of global warming has adversely influenced animal health and reproductive performance more prominently under tropical climate. t lycopene and African walnut leaf extract (AWLE) have been proven to contain bioactive components with antioxidant capability needed to improve seminal plasma biochemical indices of cockerels under tropical environment. This study was conducted to determine the effect of lycopene and AWLE on seminal plasma biochemistry indices heat-stressed cockerels 30-weeks old cockerels (n=54) were used for this experiment (10 weeks) with treatments stated as follows; Group 1 – 250ml of water, no inclusion (control), Group 2 – 7.5ml of lycopene/250ml of water, Group 3 – 15ml of lycopene/250ml of water, Group 4 – 7.5ml of AWLE/250ml of water, Group 5 – 15ml of AWLE/250ml of water, Group 6 – 7.5ml of lycopene+7.5ml of African walnut leaf extract/250ml of water, Group 7 – 15ml of lycopene+15ml of leaf extract/250ml of water, Group 8 – Vitamin C 0.1g/250ml of water, Group 9 – Cold temperature and 250mls water. The table of result is as shown in Table 1. Observation showed that cockerels under group 5 experienced a significantly depressed Malondialdehyde (0.61±0.09U/mg), while showing significant (P<0.05) elevation in seminal catalase value (741.27±21.01U/mg). It was also noted total protein value (9.75±0.23mg/dl) was significantly (P<0.05) increased under group 9, which is statistically similar with values recorded for groups 4 and 8. A reduction in MDA value and an increase in catalase under group 5 could be due to the influence of bioactive components present in AWLE. Seminal plasma proteins (SPP) enhance sperm protection, transport and fertility via improved capacitation and acrosome reaction.
