The financial implications of delays in conception at different stages of lactation in the average and the high yielding dairy cows were investigated. Variables included in the calculations were net loss in annual yield, lost income from a calf, cost of extended dry period, cost of slipping in calving pattern, cost of extra veterinary treatments and AI services, benefit of a delay in calving for reduced risk of production diseases, potential benefit of delay in conception on milk yield from the current lactation, and the value of quota leasing. For the average yielding cow, the net cost of one day of delay in conception was calculated at £2.41 when conception is delayed from 85 to 100 days post-calving, increasing to £5.02 per day if conception occurred at 146 to 175 days post-calving. After taking value of quota leasing into account, the net cost of a lost day was calculated at £1.73 and £3.55 per day for the two delay intervals respectively. For the high yielding cow, the net cost of one day of delay in conception was calculated at £2.48 when conception is delayed from 85 to 115 days post-calving, increasing to £6.52 per day if conception occurred between 206 and 235 days post-calving. The net costs after quota leasing being considered were calculated at £1.68 and £4.08 per day for the two delay intervals respectively. On the basis of the above estimations, and after considering the cost of culling for poor fertility, it was concluded that it is a cost-effective option to keep trying to get the typical average cow in calf until 266 days post-calving, whereas the breakeven point for the high yielding cow is at 290 days post-calving.

In 2016, a veterinary service company, XL Farmcare UK, was awarded a Defra contract to manage a series of on-farm demonstration workshops to raise biosecurity awareness. The workshops provided free training for cattle farmers in England on the practical measures that they could take to limit the threat of bovine tuberculosis (bTB). Despite communicating these events to farmers, the number who subsequently attended them was low and the company decided to conduct research to seek explanation. Farmers were interviewed at agricultural shows, their comments analysed and the frequency of words in use were measured to produce a set of common themes. This thematic analysis provides an illustrative rather than representative picture of farmer opinions yet holds significant explanatory value for understanding the apparent lack of engagement with biosecurity training. Broad-ranging farmer perspectives can be understood through a ‘typology’ of feelings about bTB, particularly expressions of blame, loss, confusion, ignorance, resignation and fear. The cumulative effect amounts to one of overwhelming negativity, explaining why so many farmers disengaged from training provision; a finding with relevance and value for the way training providers plan future communication methods in relation to biosecurity risk mitigation.

The milking machine can transmit infection onto teats and disturb normal teat health. Milking‐time tests allow advisors to quantify the degree to which the milking machine might be contributing to the risk of new intra‐mammary infection. Cows' teat size and position have changed as have milk flow rates. Milk yields have been rising faster than unit attachment times. Milk flow rate has been shown to be positively associated with risk of new intra‐mammary infection. Vacuum traces collected during milking can illustrate problems with biphasic milk flow or over milking and pressure records can help assess liner function. Lightweight data logging equipment is now available with excellent software to assist with interpretation.
