“…A decline in the average libido score of the rabbit bucks with increase in dietary Vernonia amygdalina leaf meal (0 to 15%) was recorded. This is in contrast with the findings of Oguike et al (2019) who observed increased libido score of rabbit bucks fed Aspilia africana leaf meal up to 20%. Evaluation of semen provide index for prediction of quality and fertility status of animals (Ajayi et al, 2011).…”

“…The 14.8% light green semen colour recorded in animals fed 15%VLM diet implies that pigment in VLM at higher concentration can penetrate the seminal duct thereby altering seminal fluid colour. High percentage of semen with milky colour recorded in this study was similar to that of Ajuogu et al (2018) and Oguike et al (2019). A normal semen sample has a homogeneous white opalescent appearance (Boiti et al, 2005).…”

“…High concentration of spermatozoa is an indication of high fertility rate because of the number of spermatozoa available at the time of copulation or insemination (Oyeyemi and Okendran, 2007;Attia et al 2017). Sperm concentration (303.53-355.42 ×10 6 /ml) reported in this study was higher than 88.00 -116.83×10 6 /ml reported by Oguike et al (2019) from the effect of Aspilia Africana leaf meal and 140.50 -250.45×10 6 /ml reported by Ogunlade et al, (2019) with Moringa olerifera leaf meal supplementation in male rabbits. The significant effect of VLM on live sperm cell in this study is in agreement with that of Oyedeji et al, (2013) who recorded a non-significant decrease in live sperm cell of rat administered Vernonia amygdalina extract for 30days.…”

The study evaluated the effect of Vernonia amygdalina leaf meal on semen indices, serum testosterone and sperm reserve of male rabbits. Forty rabbit bucks were randomly assigned into four groups and fed the experimental diets containing Vernonia amygdalina (VLM) at 0, 5, 10 and 15 % levels for 84days. Reproductive indices were evaluated using standard procedures. Data obtained were subjected to analysis of variance at p<0.05. All semen in rabbits fed 0, 5 and 10 % VLM had milky colour while 14.8% light green and 85.2% milky semen colour was observed in bucks fed 15%VLM. Libido score reduced in rabbits fed VLM diets. Bucks fed 15%VLM had significantly higher semen volume (0.47ml). VLM had no significant effect on spermatozoa mass motility, progressive motility and sperm concentration. Live sperm cells significantly increased in bucks fed 5 and 10% VLM diets. VLM had significant (p<0.05) effect on spermatozoa morphology. Vernonia amygdalina leaf meal had no significant (p<0.05) impact on testosterone, testicular and epididymal indices. In conclusion, up to 10%VLM can be adopted as feed ingredient for male rabbit breeder stock without deleterious effect on reproductive indices.

“…At 200mg/ kg of diet, it was reported that unsweetened natural cocoa powder had no toxic effect on the testicular histology of Sprague-Dawley rats (Asiedu-Gyekye et al, 2016). Conversely, Oguike et al (2019) reported a varying degree of degeneration in the histology of rabbit bucks fed Aspilia africana leaf meal when compared to the control group; and similar observation was also reported in wistar rats by Asuquo et al (2015). This outcome probably might be as a result of theobromine inherent in cocoa powder which is capable of causing debilitating effect on the testis (Smit, 2011).…”

R abbits (Oryctolagus cuniculus) have the potential to fill the gap in human protein supply, particularly in developing and underdeveloped countries. They are effective feed converters, because they can withstand up to 30 percent crude fiber compared to 10 percent in most poultry species (Egbo et al., 2001). While rabbits can be raised on a forage-based diet, according to Amao and Showunmi (2016), deficient and unbalanced grass quality, as well as seasonal availability of forage, are major constraints to successful rabbit farming. Other immense potentials of rabbit include proverbial prolificacy, high growth rate, short gestation period, high genetic selection ability, relatively low cost of production, economic utilization of space and high nutritional quality (Biobaku and Oguntona, 1997;Hassan et al., 2012). In addition, the consumption of rabbit meat is free from religious and cultural biases.

“…Sperm motility was determined subjectively with a drop of fresh semen on a glass slide covered with slip and examined using a microscope as described by Oguike et al (2019). Sperm morphology was determined by performing differential counts of the morphologically normal and abnormal structures of the spermatozoa using eosin-nigrosin stain.…”

Some researchers have inferred that folic acid is necessary for reproduction and could enhance blood formation. Thus, a Completely Randomized Design Experiment (CRD) was conducted to evaluate the impact of oral administration of folic acid on the semen and haematological characteristics of New Zealand White rabbit bucks. The treatments designated treatment 1 (T1), treatment 2 (T2) and treatment 3 (T3) having 12 rabbits each were replicated 3 times with 4 rabbits per replicate. The ages of the 36 pre-pubertal rabbit bucks were between 2 to 3 months, and weighed approximately 2.56 kg. Three experimental diets were formulated to meet the nutrient requirements of rabbit bucks. Each rabbit buck on T1 were orally administered folic acid at 0.0 mg, T2 2.5mg folic acid and T3 5.0 mg folic, respectively. Data were collected for semen characteristics and haematology from the rabbit bucks. Data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that significant increases (p<0.05) were observed on libido, semen pH, spermatozoa progressive motility (67.40-80.20%), spermatozoa live proportion (83.01-94.12%), sperm concentration (112.24-133.80 x106/ml), total number of sperm per ejaculate (50.65-67.66 x106/ml), total viable sperm (291.58-496.69 x109/ml), normal sperm proportion (85.16-91.64%). Also, significant reductions (p<0.05) were observed on the percentage head abnormality of the spermatozoa (3.74-3.18), total abnormality (2.13-0.93), mid-piece abnormality (2.35-0.79), cytoplasmic abnormality (7.17-2.89), and total abnormality (14.84-8.35); while the haematological parameters such as haemoglobin (13.53-14.20g/dl), packed cell volume (33.00-34.96%), white blood cell (6.81-7.80 x103mm3) and the differential white blood cells improved significantly (p<0.05) following the oral administration of folic acids to the rabbit bucks. Thus, the oral administrations of folic acid at 5.0 mg per rabbit buck most significantly improved the semen characteristics, enhanced the overall spermatozoa morphology, reduced sperm cells abnormalities and also improved some haematological parameters of the rabbit bucks.
