Pig Feed Formulae
#1
I will like to share with you guys this pig feed formulae that gave high growth rate of 721g per day. But note that improved pig breeds were used and that matters a lot. Feeding local hens quality feed will not make them grow like broilers. You get it?

Pig breed used in the research was a hybrid of Yorkshire-Hampshire-Landrace-Duroc. But you can use other improved breeds with good result. And here is the feed:

Sweet potato leaves and stems were chopped and fed to the pig adlibitum (that is, it was made available at all times). In addition to this, a protein supplement was given at 1.6kg per pig per day till they reach 60kg body weight. Let's call this "feed 1". Initial body weight at the start of the experiment was about 30kg.

From 60kg body weight to 90kg body weight, "feed 2" is given at 1.8kg per pig per day.

Formulae for feed 1 is:
Maize: 52kg
Soybeans meal: 31.4kg
Palm oil: 12.5kg
Limestone (calcium carbonate): 0.8kg Calcium phosphate: 2.5kg
Salt: 0.5kg
Vitamin-mineral premix: 0.2kg

Feed formulae 2 is:
Maize: 57.2kg
Soybeans meal: 26kg
Palm oil: 12.5kg
Limestone (calcium carbonate): 0.87kg Calcium phosphate: 2.49kg
Salt: 0.5kg
Vitamin-mineral premix: 0.2kg DL-Methionine: 0.03kg
DL-Lysine: 0.15kg

So if you are a potato farmer, you can consider using the diet above to fatten pigs. One way to guarantee constant supply of sweet potato leaves is by ensilaging it with corn/cassava flour.

In the experiment, the diet above was compared to a costly control diet. Control diet formula 1 fed till 60kg body weight is shown below:
Maize: 78kg
Soybeans meal: 17.4kg
Palm oil: None
Limestone (calcium carbonate): 0.586kg Calcium phosphate: 2.42kg
Salt: 0.5kg
Vitamin-mineral premix: 0.2kg DL-Methionine: None
DL-Lysine: 0.6kg

Control Diet 2 fed from 60kg to 90kg body weight is:
Maize: 78.8kg
Soybeans meal: 17.4kg
Palm oil: None
Limestone (calcium carbonate): 0.58kg Calcium phosphate: 2.42kg
Salt: 0.5kg
Vitamin-mineral premix: 0.2kg DL-Methionine: None
DL-Lysine: 0.06kg

The control diets gave an average of 779g body weight gain per day and a feed conversion ratio of 2.52kg per kg gain.
Thanks.

Some of these ingredients will be difficult to get. Are there alternatives?

You can get most of them in animal feed stores. Just search and you will find. But you can still replace Limestone (calcium carbonate) with egg shell; Calcium phosphate with bone meal.

A feed conversion ratio of 2.52kg per kg gain means that they eat 2.52kg of feed to gain 1kg in body weight.
