Improvement of Growth performance in piglets after Feeding Nursery diet supplemented with HYPER-EGG K88® and infecting piglets with ETEC K-88 bacteria

Study performed: University of Minnesota
Number of piglets used in the study: Thirty 18-day old piglets and six were in each group.
Feeding regimen: Each group were fed nursery diet supplemented with EG, (4Kg control egg powder from unimmunized group/T of feed), or ABEG 0.2%, (2Kg HYPER-EGG K88®/T of feed), or ABEG 0.4% (4Kg HYPER-EGG K88®/T of feed), or ABDEX 0.2% (1Kg of HYPER-EGG K88® + 1Kg Dextrose/T of feed), or ABDEX 0.4% (2Kg of HYPER-EGG K88®+ 2Kg Dextrose/T of feed), for 14 days, from day 1 to day 14, post-weaning. Piglets were fed normal diet during day 14-28.
Infection with ETEC K88: All piglets were infected orally on day 7 post-feeding with 1012 CFU of ETEC K88. • Study parameters: Clinical response (incidence of diarrhea, severity of diarrhea, enumeration of ETEC K88 from rectal swab) and changes in J. H. Hare & Associates Ltd.

Improvement of Growth Performance of post-wean piglets following feeding with nursery diets supplemented with HYPER-EGG® K-88

Study performed at the Department of Animal Sciences, University of Manitoba, Winnipeg, Canada. -September-December 2010.
Study Directors: Dr. Martin Nyachoti, Professor, Department of Animal Sciences, University of Manitoba and Dr. Pradip K. Maiti, Vice-President & Chief Scientific Officer, J.H. Hare & Associates Ltd.
Study Personnel: Dr. Kiarie Elijah, University of Manitoba

Study Objectives: To determine the effect of supplementing pig starter diets with HYPER-EGG® K-88 product on growth performance of newly-weaned piglets
Methods: Three groups of 21-day old piglets, 24 piglets in each group, were used in the study. Piglets in Group 1 were fed with Phase I nursery diet; piglets in Group 2 were fed with Phase I nursery diet supplemented with 0.3% HYPER-EGG K-88, when piglets in Group 3 were fed with diet supplemented with 5% Spray-dried plasma, for 14 days, day 0- day14. Piglets in all three groups were then fed with phase II diet without any supplement, as illustrated in Table -1. The growth performance and feed intake were monitored on days, 7, 14 and 25, post-feeding, to assess growth performance of piglets.

Results: The growth performance of piglets fed with both HYPER-EGG and Plasma showed improvement on day 7, 14 and continued on day 25, as compared to the control piglets. The average body weight was increased by 1.1Kg on day 25 in the HYPER-EGG fed animals over the control group. Interestingly, the highest ADG (428g) was achieved on day 25, in the group that was fed with HYPER-EGG K-88 for 14 days. The results are shown in Tables 2-3 and Figures 1-2.
Conclusions: The growth performance of post-wean piglets have been improved by 1.1 kg on day 25, after feeding piglets for 14 days with nursery diet supplementing with 3Kg of HYPER-EGG K-88® per metric ton of feed.
