Management notes

Tillage: Lower than normal temperatures are slowing recent crop development and this could increase management challenges around earing out and flowering.

Sheep: Anthelmintic resistance is a major threat to efficient production, with a worrying increase in the rate at which resistance is developing.

Dairy: For every one-day delay in harvest after heading date, silage quality declines by 0.5% dry matter digestibility (DMD).

Beef: Lungworm control, grass tetany prevention and upcoming KT approved beef health events.
