1 Feeding Swine

2 Introduction There are two main factors that determine whether a person is profitable in the swine industry 1. # of pigs weaned per sow per year 2. feed efficiency Large corporate farms currently wean an average of pigs per female per year.

3 How many? Females should be bred and managed to produce a minimum of 2.3 liters per year.

4 Selecting Feeds for Swine
Feed costs range from 55-70% of the total cost of raising hogs. Combining the right kinds of feed in a well-balanced ration is one of the most important tasks of a hog producer. The nutrient needs of hogs include energy, protein, minerals, vitamins, and water.

5 Energy Feeds Corn is the basic energy feed used in hog rations.
It is high in digestible carbohydrates, low in fiber, and palatable. Corn is about 8.8% protein.

6 Energy Feeds Barley- good substitute for corn.
Has a higher fiber content so is less digestible than corn, but more protein Like corn lacks some of the essential amino acids and should be supplemented with a protein supplement. Not quite as palatable

7 Energy Feeds Oats- more protein than corn, but poorer quality protein. High fiber content. Potatoes- most carbs, heavier hogs make better use, take 4X as much potatoes as corn to equal the same feed value Bakery Wastes- include stale bread, crumbs, cookies, crackers; average 10% protein

8 Plant Proteins Soybean oil meal % protein content, excellent quality of protein, most widely used protein source for hogs, is very palatable to hogs Whole soybeans- about 37% protein, higher in energy and lower in protein than oil meal, cannot feed raw soybeans to hogs due enzyme reactions

9 Animal Proteins Tankage & Meat Scraps % protein, high content of calcium and phosphorous, not near as palatable as soybean meal Meat & Bone Meal- 50% protein, amount of bone contained in the mix determines the feeding value Fish Meal % protein, excellent quality, high in minerals and vitamins and is very palatable, but expensive

10 Minerals Four major minerals and six trace minerals are frequently added to hog rations. Major: calcium, phosphorous, sodium, and chlorine Trace: zinc, iron, copper, selenium, manganese, and iodine Trace minerals are often found in commercial protein supplements or trace-mineralized salts

11 Vitamins Many of the vitamins required by hogs are already present in the feeds used in hog rations Vitamins that must be added to the ration are: A, D, E, K, riboflavin, niacin, panothenic acid, choline, and vitamin B12.

12 Water Most important nutrient in all animals diet.
Should be available at all times. Should be fresh, clean, and no colder than 45 F Should be checked periodically for nitrate content Average sow = 3.5 gallons/day

13 Additives Increase efficiency in hog production.
Enable pigs to grow at a faster rate, improve feed conversion, and reduce disease stress Feed tag instructions must be carefully followed in the use of additives. Withdrawal times must be observed when marketing hogs.
