Effects of Hydrolysed Vegetable Protein or Hydrolysed Vegetable and Meat Protein Blend on Nursery Pig Performance

21 February 2014

Including the speciality protein products in the diets of weaned pigs had no positive effects on their performance in this experiment, which was reported at the 2013 Kansas State University Swine Industry Day.

The effects of feeding hydrolysed vegetable protein or a blend of hydrolysed vegetable and meat protein to pigs in the nursery weighing between 15 and 40 pounds were reported in a paper by first-named author, M.A.D. Goncalves.

A total of 280 pigs (PIC 327 × 1050, initially 16.7 lb bodyweight) were used in a 28-d trial to evaluate the effects of hydrolysed vegetable protein or a blend of hydrolysed vegetable and meat protein for nursery pigs.

Three days after weaning, pigs were allotted to one of four dietary treatments in a completely randomised design, balancing for initial bodyweight and gender. There were 10 pens per treatment with seven pigs per pen.

The four diets were:

  1. no added specialty protein source (negative control)
  2. 6.0 per cent select menhaden fish meal
  3. 5.0 per cent hydrolysed vegetable protein (Hydr SF 52, International Ingredient Corporation) or
  4. 6.5 per cent hydrolysed vegetable and meat protein blend (HDSF Protein; International Ingredient Corporation).

Diets were fed in two phases, with Phase 1 from days 0 to 17 (treatment diets) and Phase 2 from days 17 to 28 (common diet).

From days 0 to 17, pigs fed the negative control diet had a superior (P≤0.05) feed:gain ratio to those fed diets with Hydr SF 52 or HDSF Protein. No differences in average daily gain or average daily feed intake were detected among treatments.

From days 17 to 28 (common period), no difference was observed in growth performance between pigs previously fed any of the treatment diets.

Overall (days 0 to 28), no differences were observed in average daily gain, average daily feed intake or feed:gain ratio among pigs fed any of the treatment diets.

Because performance did not differ from pigs fed the negative control diet, definitive conclusions regarding these specialty protein sources cannot be made.
