Background: Heat stress results in a mild reduction in milk production, while long-term heat stress exposure can severely affect the productive and reproductive performance in dairy cattle.
Aim: To quantify the relationship between reproductive performance and temperature-humidity index in dairy cattle farms in Lima, Peru.
Methods: Monthly service, conception, and pregnancy rates were measured from four dairy farms in four different Lima localities as reproductive performance indicators, along with an index of heat stress and maximum daily temperature-humidity index (max THI), during a 3-year period.
Article Synopsis
- The study aimed to assess different methods (pasteurization, freezing, formaldehyde, and peroxymonosulfate) for eliminating the bovine leukemia virus (BLV) in milk.
- A bioassay was performed on 40 sheep, with five groups: one untreated control and four treated with the inactivation methods over a 10-week observation period.
- Results showed that pasteurization, freezing, and formaldehyde effectively inactivated BLV, with no seropositive sheep in these groups, unlike the control and peroxymonosulfate groups.
