strike: the infestation of the flesh of sheep by the larvae of blowflies. It causes extreme irritation and death can occur in a short time. Managing strike ensures sheep health and productivity, preventing losses and supporting farm profitability.

salt poisoning: A disease of pigs usually caused by inadequate provision of water, but which may also be caused by increased salt in the ration. Pigs become constipated before twitching, fits and death. Farmers benefit from preventing salt poisoning by ensuring proper water provision and diet management.

sustainable consumption and production: the idea that agricultural production should not cause environmental damage, exploit workers, or use up natural resources that cannot be replaced. Abbr SCP. Understanding and implementing sustainable consumption and production practices ensures responsible resource use and supports farm sustainability.

selective breeding: The process of choosing parent organisms with desirable traits to produce offspring with those traits. Selective breeding improves crop and livestock quality.

spay: to remove the ovaries of a female animal. Properly managing spaying supports livestock health and population control, promoting sustainable farming practices.
