A piggery sets up a series of opportunities. By designing your piggery from the ground up to reuse waste it can become your power station and petrol station. The pigs need feeding so you need three or four fenced paddocks, these can be partly planted in orchards and need some small crops area. In the small crops area you would plant sugar beet, potatoes, corn and other high sugar / carbohydrate plants. These would be harvested and turned into alcohol of an industrial grade this is then used as a blend with petrol or diesel to fuel farm machinery. Waste from this process is used to fertilise small crops. The choicest of the feed is fed to the pigs fresh. The piggery is designed with a grated or slatted floor to make cleaning easy. Pigs in the wild feed at night and sleep or wallow during the day, so in keeping with this you would provide this in the piggery. Bringing the pigs in at dawn supplying food and bedding. All collected waste is then washed into a sludge converter where it ferments giving off methane gas, which is collected and burned through a turbine,(methane can also be used to power most four stroke petrol motors,) to produce electricity. Waste from this is fertiliser again. By rotating the paddocks that the pigs forage in, you get the advantage of the pigs cleaning up the food left after a paddock is harvested, damaged and wind fall fruit from orchard. They dig and aerate the soil. Herding the pigs back to the piggery at dawn (They will do this by them selves after a little while, relieving you of the necessity of getting up at dawn, an added bonus.) lets the humans work in these paddocks during the day. Once again the pigs are the primary product with organic pork supplied to the market at a good price, and the other by products supplying fuel and power which you would other wise be paying for. If you produce more electricity than you can use, this can be sold to the power distribution companies this is pure profit (after set up costs). Some large piggeries in Victoria Aust make more money selling green power to the power companies than they make out of raising pigs.
Cattle and sheep do a lot of damage to the environment, feed lots can reduce this considerably. I know feed lots as they stand are decusting, so lets modify this idea.
By making the lots bigger(or putting less animals into it) and taking into consideration some of the animals needs, shelter, water and waste we can come up with something much better.
Shelter, water and waste can all be managed in the design stage of the feeding bays. By designing your feed bays with a roof and three sides and a raised slated floor, you achieve solutions to these problems. You safe costs because the feed is out of the weather, so it all gets eaten, the cattle have shelter, fresh water can be collected off the roof and supplied for stock water and cleaning, and the waste from this area can be collected easily. This also allows easy cleaning on a daily or weekly basis. By possesioning this close to, or around your piggery/methane generator you can use gravity or a sludge pump to move this waste into the generator, stopping it escaping into the environment.
Trees fruiting or forestry are planted around the feed lot boundary to offer protection from the weather and to use the nutrients left as a result of the live stock.
Excess manure deposited outside the feeding bays should be collected and returned to the generator.

Value adding to livestock at this time dose not appearer to be possible, as this requires killing and processing the animals, which is expensive to set up and involves a lot of government regulations. And bad kama, let someone else do that.
