An evaluation of peptone products and fish meal on nursery pig performance
A total of 360 nursery pigs (PIC C327 × 1050, initially 11.8 lb and 21 d of age) were
used in a 35-d study to evaluate the effects of select menhaden fish meal (SMFM),
PEP2+ (also known as Ferm O Tide), Peptone 50, and PEP-NS on nursery pig performance.
PEP2+, Peptone 50, and PEP-NS are all porcine intestinal mucosa products,
but differ based on the carriers with which they are co-dried. PEP2+ is co-dried with
enzymatically processed vegetable proteins. Peptone 50 is co-dried with a vegetable
protein, while PEP-NS uses by-products from corn wet-milling. Phase 1 diets were
fed in pellet form from d 0 to 8. Phase 2 diets were fed in meal form from d 8 to 21. A
common corn-soybean meal diet was fed from d 21 to 35. There were 6 dietary treatments:
(1) a negative control diet containing 2.5% spray-dried animal plasma (SDAP)
in Phase 1 followed by no specialty protein sources in Phase 2; (2) a diet containing 5%
SDAP in Phase 1 and 3% SMFM in Phase 2; (3) a blend of 5% SDAP and 3% SMFM
during Phase 1 and 6% SMFM during Phase 2; (4) a blend of 5% SDAP and 3% PEP2+
during Phase 1 and 6% PEP2 during Phase 2; (5) a blend of 5% SDAP and 3% PEP 50
during Phase 1 and 6% PEP50 during Phase 2, and (6) a blend of 5% SDAP and 3%
PEP-NS during Phase 1 and 6% PEP-NS during Phase 2. During Phase 1, there were
no differences in F/G among pigs fed any of the dietary treatments. During Phase 2 (d
8 to 21), pigs fed 6% PEP2+ had greater (P < 0.05) ADG compared to those fed the
negative control diet, 3% or 6% fish meal, with pigs fed PEP50 and PEP NS intermediate.
Furthermore, pigs fed 6% PEP2+ had the greatest improvement (P < 0.02) in F/G
compared to pigs fed all other experimental diets. Overall, pigs fed diets containing
PEP2+ had increased (P < 0.03) ADG and ADFI compared to pigs fed the negative
control diet. Pigs fed 3% PEP2+ during Phase 1 and 6% PEP2+ during Phase 2 had
greater (P < 0.05) ADFI compared to those fed 3% SMFM during Phase 1 and 6%
SMFM during Phase 2. In conclusion, PEP2+, Peptone 50, and PEP-NS can be used
as specialty protein sources to replace select menhaden fish meal in Phase 2 nursery pig
diets. In addition pigs fed PEP2+ had greater ADG than those fed fish meal
Effects of Liquitein on weanling pigs administered a Porcine Circovirus Type 2 and Mycoplasma hyopneumoniae vaccine strategy
A total of 180 nursery pigs (PIC 327 × 1050, initially 12.6 ± 0.22 lb, and 19 ± 2 d of
age) were used in a 35-d study to determine the effects of Liquitein and a porcine circo-
virus 2 (PCV2)/Mycoplasma hyopneumoniae (M. hyo) vaccine regimen on the growth
performance of weanling pigs. Liquitein (TechMix, LLC Stewart, MN) is a watersoluble
source of plasma and energy provided in the drinking water immediately after
weaning. Pigs were randomly allotted to 1 of 4 treatments arranged in a 2 × 2 factorial
with main effects of Liquitein (with or without) and PCV2/M. hyo vaccine regimen
(vaccinates or non-vaccinates) with 5 pigs per pen and 9 pens per treatment. At wean-
ing, pigs in the vaccinate group were given a full dose (2 mL) of ResprisureOne (Pfizer
Animal Health, New York, NY) and Circumvent (Intervet/Schering-Plough Animal
Health, Millsboro, DE). On d 21, pigs in the vaccinate group were administered a
second full dose (2 mL) of Circumvent per label instructions. Liquitein was adminis-
tered to the pigs via water medicators for the first 5 d after arrival to the nursery. No
vaccine × Liquitein interactions occurred for ADG or F/G throughout the study. From
d 0 to 5, non-vaccinated pigs had a tendency (P < 0.07) for increased ADG. From d 21
to 35, pigs previously administered Liquitein had greater ADFI (P = 0.05) than those
not provided Liquitein; however, overall (d 0 to 35) Liquitein had no effects on growth
performance. From d 0 to 35, vaccinated pigs had decreased (P < 0.01) ADG and ADFI
compared with non-vaccinated pigs. In conclusion, administering Liquitein during
the first 5 d in the nursery increased feed intake later in the nursery stage (d 21 to 35),
but the response was not great enough to influence overall growth performance. Pigs
administered the PCV2 and M. hyo vaccine regimen had decreased ADG and ADFI
Evaluation of heparin production by-products in nursery pig diets
A total of 1,152 weanling pigs (Newsham GPK35 × PIC380, initially 12.3 ± 1.30
lb, 20 ± 2 d of age) were used in a 39-d study to evaluate the effects of select menha-
den fish meal (SMFM), poultry meal, PEP2+, Peptone 50, and PEP-NS on nursery
pig performance. PEP2+, Peptone 50, and PEP-NS are all porcine intestinal mucosa
products, but they differ in the carriers with which they are co-dried. PEP2+ is co-dried
with enzymatically processed vegetable proteins and amino acid (AA) dried fermentation biomass. Peptone 50 is co-dried with a vegetable protein, whereas PEP-NS uses
by-products from corn wet-milling as well as dried fermentation biomass.
Pigs were randomly allotted to 1 of 6 dietary treatments with 32 pigs per pen and
6 replications per treatment. Treatment diets were fed in 2 phases (d 0 to 7 and d 7
to 21) with a common diet fed to all pigs in the third phase (d 21 to 39). Treatments
consisted of a negative control (NC) diet containing 4.5% SDAP in Phase 1 and no
specialty protein sources in Phase 2 or the NC diet with 6% poultry meal (PM), PEP2+,
Peptone 50, or PEP-NS. From d 0 to 21, pigs fed diets containing 6% SMFM, PM,
PEP2+, or PEP-NS had improved (P < 0.05) ADG and ADFI compared with those fed
the negative control diet. Pigs fed diets containing 6% SMFM, PM, PEP2+, or PEP-NS
had improved (P < 0.05) F/G compared with pigs fed 6% Peptone 50.
From d 21 to 39, pigs previously fed diets containing 6% PEP2+ or PEP-NS had
improved (P < 0.05) ADG and ADFI compared with those previously fed the negative
control diet. Overall (d 0 to 39), pigs fed diets containing 6% SMFM, PM, PEP2+, or
PEP-NS had improved (P < 0.05) ADG and ADFI compared with pigs fed the negative
control diet. No significant differences were observed among treatments for F/G;
therefore, PEP2+ and PEP-NS are suitable replacements for fish meal and poultry meal
in nursery diets from d 7 to 21 postweaning
