Male libido and the success of semen collection were significantly higher around spring equinox (P less then 0.05). Changes in photoperiod in the southern hemisphere do not affect semen production in ostriches. However, high sperm output and male libido around spring equinox and summer solstice dates suggest that these periods may be preferred for semen collection for artificial insemination and storage purposes.Methicillin-resistant Staphylococcus aureus (MRSA), an important widespread cause of severe infection in both humans and animals, is a significant pathogen of public health concern. This study examined the presence of MRSA in 400 samples comprising 200 raw milks (145 from goat and 55 from sheep) and 200 nasal swabs (145 from goats and 55 from sheep) collected from ten different locations in Abeokuta, Nigeria. Samples were examined using standard bacteriological methods for the isolation and identification of Staphylococcus aureus and culture on oxacillin (6 μg/ml) and cefoxitin (2 μg/ml) selective media for the detection of MRSA. Suspected MRSA isolates were confirmed by latex agglutination test for the detection of penicillin-binding protein 2a (PBP2a). Antibiotic susceptibility testing was determined by Kirby Bauer disc diffusion method. Staphylococcus aureus was detected in 72 (18%) of 400 samples of which 52 (13%) were confirmed as MRSA. Methicillin-resistant S. aureus was detected in raw milk (37 of 200; 18.5%) and nasal swab (15 of 200; 7.5%). There was no significance difference (p > 0.05) in the prevalence of MRSA in sheep (37.7%) and goat (23.4%). The MRSA isolates showed resistance to ampicillin (100%), cloxacillin (100%), sulphamethoxazole-trimethoprim (100%), amoxicillin-clavulanate (84.6%), ceftriaxone (75%), cefuroxime (69.2%), erythromycin (65.4%), streptomycin (38.5%), ciprofloxacin (23.1%), pe
