“…However, the buck breeds had the different activity of various antioxidants in response to the antioxidant demand of the system for ROS scavenging, which is evident in low seminal lipid peroxidation. The antioxidant enzyme activity of the rabbits assessed was better than values reported by Jimoh, Ewuola, and Balogun (2017) at the peak of heat stress. This infers that the animals have better antioxidant status at thermal comfort compared to when exposed to heat stress.…”

“…This infers that the animals have better antioxidant status at thermal comfort compared to when exposed to heat stress. This claim is buttressed by the low lipid peroxidation recorded in this study compared to Jimoh et al (2017) values recorded for seminal lipid peroxidation in heat stressed rabbits. It is thus inferred that rabbit oxidative stability which could influence immune status and productivity is better when rabbits are at thermal comfort giving the fact that oxidative stress due to hyperthermia apparently reduces the activity of antioxidant enzymes which could result in impairment of sperm membrane integrity.…”

Background: Within the rabbit population in South West of Nigeria, four exotic breeds of rabbits consisting of Fauve de Bourgogne, Chinchilla, British Spot, and New Zealand White were evaluated for their reproductive response. This investigation was carried out within July and August, when the least temperature-humidity index (THI) (ranged between 23.41 and 25.30) is observed in Ibadan, South West, Nigeria, which depicts the highest thermal comfort in the study area. Thirty bucks per breed, housed individually and randomly allotted to experimental units, were used for this study. All bucks were made to serve an artificial vagina, libido was evaluated, and the collected ejaculates were assessed for semen characteristics, seminal biochemical parameters, and oxidative stress indices weekly for 4 weeks. Two ejaculates per buck were collected weekly. The first ejaculate for spermiogram and the second ejaculate was centrifuged at 4000 rpm for 15 min to separate seminal plasma and used for biochemical analysis using standard procedures. Result: The result obtained revealed that sexual urge (reaction time) in the four breeds was similar statistically. British Spot and New Zealand White breeds despite recording a lower semen volume had apparently higher mass motility, individual sperm motility, and significantly higher (P < 0.05) sperm concentration compared with the other breeds. Genetic differences in breeds were evident in most oxidative stress markers, except for the total antioxidant activity of seminal fluid. New Zealand White had the highest antioxidant enzyme activity. Conclusion: New Zealand White had the best oxidative status among the four breeds, and this enhanced its semen quality parameters among the rabbit breeds.

“…The reactive oxygen radicals produced during the process of food digestion in the digestive tract can attack the intestinal mucosa surface and thereby affect the normal process of nutrient absorption. Therefore, the anti-inflammatory and antioxidant activities in the intestinal mucosa may result in maintenance of healthy gut morphology (Kamel, 2000), improved increased nutrient absorption and enhanced growth (Cardoso et al, 2012) as recorded in this study. Previously, Li et al (2018) reported improved daily weight gain, average feed intake in rabbits' whose diets were supplemented with 1 or 5 g/kg Eucommia ulmoides leaves, while Ayodele et al (2016) reported improved feed conversion ratio in rabbits fed on 5 or 10% alchornea leaf meal inclusion diets.…”

The effects of dietary Mucuna pruriens leaf meal (MLM) supplementation on rabbits’ performance, haemato-biochemical indices and antioxidant status outside their thermal neutrality zone (21 to 25°C) were evaluated. One hundred and twenty 35-d old crossbreed (Chinchilla×New Zealand) rabbits weighing 694±5 g were allotted to 4 treatments (30 rabbits/treatment; 3 rabbits/replicate). A basal diet (crude protein: 16.9%, crude fibre: 17.6%, digestible energy: 2671 kcal/kg) was divided into 4 equal portions i.e. diets 1, 2, 3 and 4, supplemented with 0, 4, 8 and 12 g MLM/kg, respectively, and pelleted. The average body weight in rabbits fed on diets 3 and 4 was higher compared to those fed on diet 1 (control) at 91 d of age (+228 and +262 g, respectively; P=0.01). Within 35 to 91 d, the average daily weight gain in rabbits fed on diets 3 and 4 was higher compared to those fed on the control diet (+4.1and +4.8 g/d, respectively; P=0.01). The dressing-out percentage of rabbits fed on diets 3 and 4 increased (P=0.05) compared to those fed the control diet. At 63 d and 91 d of age, the white blood cell level of rabbits fed on diet 4 increased significantly compared to those fed the control diet (+5.05×109 and +5.32×109/L, respectively). At 63 and 91 d of age, the cholesterol level of rabbits fed on diets 3 (–1.0 and –1.16 mmol/L, respectively) and 4 (–1.10 and –1.21 mmol/L, respectively), were significantly lower compared to those fed on the control diet. The aspartate aminotransferase (AST) concentration in rabbits fed on diet 4 was reduced compared to those on control diet at 63 d of age (–33.68 IU/L; P=0.02). At 63 d and 91 d of age, compared to control, the activities of glutathione peroxidase in rabbits fed on diets 3 (+35.77 and +49.09 mg protein, respectively) and 4 (+54.52 and +55.02 mg protein, respectively) increased significantly, while catalase activities in rabbits fed diet 4 (+217.7 and +209.5 mg/g, respectively) also increased significantly. It could be concluded that dietary MLM supplementation enhanced the rabbits’ performance, reduced serum AST and cholesterol and improved the antioxidant status.

“…The effect of the different leaf meals supplementation on body weight gain (BWG), feed intake (FI) and FCR are presented in The flavonoids and phytate were reported to produce antioxidant effects (Makkar, Siddhuraju, & Becker, 2007;Middleton, Kandaswani, & Theoharides, 2000). Antioxidant effects reduce intestinal mucosa damage and muscle protein hydrolysis being caused by free radicals (Jimoh, Ewuola, & Balogun, 2017;Li et al, 2018). The phytochemicals (e.g., flavonoids and phytate) present in these leaf meals could have produced antioxidant and free radical scavenging activities to maintain the integrity of the intestinal mucosa and promote growth performance (Yuan, Chen, Zhang, & Yu, 2007).…”

Neem, pawpaw and bamboo leaf meal dietary supplementation in broiler chickens: Effect on performance and health status

et al. 2018

The effect of the diet supplemented with leaf meals (LM) of neem (NLM), pawpaw (PLM), bamboo (BLM) and their composite leaf mix (CLM) on broiler chickens was assessed. Three hundred 1‐day old broiler chickens were distributed to five diets: (control/no LM), (5 g/kg NLM), (5 g/kg PLM), (5 g/kg BLM) and (5 g/kg NLM+PLM+BLM 1:1:1). Body weight gain of birds fed BLM and CLM supplemented diets were similar but higher (p < 0.05) than those fed the control, NLM and PLM supplemented diets at day 42. The glucose, triglycerides, cholesterol, alanine aminotransferase and creatinine levels in LM supplemented diets were (p < 0.05) lower compared to the control. The superoxide dismutase, glutathione peroxidase and catalase were (p < 0.05) higher in LM supplemented diets compared to the control. The growth promoting potentials of bamboo leaf meal and the composite leaf mix can be harnessed for broiler chicken production. Practical applications The use of herbs as the growth promoter is currently gaining research attention in most countries. In particular, herbal supplementation in poultry diets had been proposed as a means of enhancing the performance, stabilizing the physiological state, boosting immunity and antioxidative status in the birds. This study showed that improved body weight gain of broiler chickens at 42 days of age with attendant low serum glucose, triglycerides and cholesterol can be achieved when leaf meals from neem, pawpaw, bamboo and their composite mix were used as phyto‐additives. The bamboo leaf meal and the composite leaf meal can be used to reduce the occurrence of arteriosclerosis which predisposes sudden death syndrome in well‐grown and healthy broiler chickens. The procedures of raising broiler chickens to reach about 3 kg in less than 2 months impose a heavy burden on the heart, particularly overloading on the ventricular arteries leading to arteriosclerosis with age.
