“…A plausible mechanism for an increase in the NSC, NPC and PPA in cows with SCMA is a disturbance in hypothalamic-pituitary-ovarian-uterian axis (Sharma et al, 2017) through a depression of gonadotropin-releasing hormone which delays follicle growth, ovulation, and functioning of corpus luteum (Heravi, Danesh, & Gilbert, 2012). In their study, Sharma et al (2017) concluded that poor reproductive performance in SCMA positive cows could be linked to the fertilization failure, impaired oocyte development, altered hormonal profile, and unfavorable uterine milieu for embryonic development. Furthermore, Ribeiro et al (2016) reported that SCMA interferes with feed intake, an expenditure of energy and nutrients which results in lowering body condition and delaying the resumption of the postpartum ovarian cycle.…”

Mastitis is one of the most important diseases affecting production and reproductive efficiency of dairy cows. The objective of this study was to estimate the prevalence of subclinical mastitis (SCMA) and its effects on reproductive performance in postpartum dairy cows. In a cross-sectional survey, sample cows (n = 200) within their 10-40 days in milk from smallholder farms (n = 159) were selected and tested for SCMA using California Mastitis Test. They were classified into two groups: cows with SCMA (SCMA group, n = 101) and cows without SCMA (WSCMA group, n = 99). Reproductive performance including calving-to-first-oestrus interval (CFOI), calvingto-first service interval (CFSI), calving-to-conception interval (CCI), cows that remained non-pregnant, postpartum anoestrus, and total number of services per conception were recorded for 150 days in milk. The overall prevalence of SCMA recorded was 50.5%. The mean number of days for CFOI was significantly longer (p<0.05) in cows with SCMA (87.6±4.8 days) than in cows WSCMA (72.5±4.3 days). The mean days for CFSI was significantly longer (p<0.05) in cows with SCMA (97.2±5.6 days) than in cows WSCMA (78.9±4.9 days). The difference between the CCI of the SCMA positive cows (107.8±7.4 days) and that of the negative ones (62.5±4.5 days) was statistically significant (p<0.001). Cows with SCMA required more breeding services (p<0.05) to conceive (1.9±0.1 services) than cows WSCMA (1.2±0.1 services). Results indicate that SCMA had significant negative effect on fertility performance. Therefore, improving management interventions to prevent and control SCMA is essential for reducing its adverse effects in dairy cows.

“…mineral elements may cause reproductive disorders as minerals play an important role in health and reproduction of the livestock (Sharma et al, 2007). Minerals are required for normal functioning of basically all biochemical processes of the body and acts as catalysts in both enzyme and hormones systems (Suttle, 2010).…”

“…It is the most complex dairy cow disease which is negatively affecting milk production. It is commonly caused by bacteria in dairy cattle and characterized by the chemical, physical and bacteriological changes occurring in the milk (Gunay and Gunay 2008;Sharma et al 2017). In the dairy industry, it is a disease with an important economic impact which results in huge losses (Bradley et al 2007).…”

“…The most common pathogens responsible for subclinical bovine mastitis are S. aureus, S. agalactiae, and other Streptococcus species and Coliforms (Sharma et al 2017). Antibiotic resistance in bacterial and fungal species is significantly increasing which causes diseases like mastitis incurable using antibiotics.…”

Bovine mastitis is an inflammation of mammary gland parenchyma in cows. It is caused by multiple pathogens that result in economic losses because of the reduction in milk production and poor quality of the milk. It is commonly caused by bacteria that multiply in the mammary gland and regional lymph nodes, damaging the mammary parenchyma. The present study focuses on the bovine mastitis treating capacity of zinc oxide nanoparticles by examining in vitro antibacterial activity, MIC and MBC against pathogens isolated and identified from sub-clinical mastitis in dairy cows. Zinc oxide nanoparticles were synthesized both chemically and green methods from a plant extract of Coriandrum sativum and characterized for phase and microstructural analysis. The milk sample from subclinical mastitis cows was collected from the veterinary hospital. The bacteriological examination revealed the presence of S. aureus and E. coli. The antibacterial activity of the zinc oxide nanoparticle was evaluated at 650, 850, 1300, 1700, 1950 and 2500 µg/ml concentrations and the minimum inhibitory concentration was found to be 650 µg/ml and 850 µg/ml for S.aureus and E.coli respectively, and minimum bactericidal concentration was 650 µg/ml and 1700 µg/ml for S. aureus and E. coli respectively.
