Ah, pork st 2 I've got!
Keep the cow until it drops 1 milk. Two bears will appear right about this time. The dogs should be able to cage them but avoid getting them in your warehouse just yet. You need to sell off the cow and the milk first. Once they're (the cow and milk) on their way in the truck, warehouse the two bears.
When the truck returns and you're "rich", immediately buy 1 pig, 5 chickens, upgrade both existing egg plants to max, upgrade truck once, sell the bears, and send the plane for 5 sugars.
By the time the truck comes back from selling the bear, you should have 5 eggs and a ham in your warehouse. If not, it should happen quickly. Sell off the chickens, the pig and any bear that might be in the warehouse.
Process the eggs and ham, clicking on the egg plant, trapping and selling bears as you can. As soon as the steak pops out, buy the confectionery, upgrading it as much as your money allows. With the sale of the steak and any bears, you might get another upgrade, but with clicking even without additional upgrades, you'll finish well under gold time.
