The delivery weight, price per pound, and weight slide should be negotiated when you contract to purchase the animals. You should aim to purchase 500-600 lb animals that are 5 months-6 months old and preferrably have been weaned at least 30 days and have been vaccinated. How long you keep them depends on how long your forage holds out. Commonly winter stockers on small grain are held 100 days and should gain 150-250 lb/ head in that time depending on their genetics. Summer stockers are grazed until the forage gives out which will vary greatly depending on which part of the country you are in.
