Nutrition Notes | Innovative New Pig Starter Formulations for Nexgen® 5-10, Nexgen® 8-13 and Nexgen® 12-17 Facebook Twitter LinkedIn The use of animal plasma in early wean pig starters in 1990 resulted in significant improvements in performance. In early 2014, a new ingredient called betaGRO® (a concentrated source of immunoglobulins from animal plasma) became incorporated into pig starters as a replacement for animal plasma. At the Kent Nutrition Group, we have been evaluating many specialized ingredients during the last 20 years that can help with growth and the immune status of pigs. Based on extensive research during this time span, we now utilize within our nursery feed program: Micro-Aid® Proprietary hydrolyzed yeast cell wall that is a source of Mannan Oligosaccharides (MOS) that provides a source of prebiotics Egg Proteins that provide a source of antibodies that may help with various stressors Selenium Yeast as a highly bioavailable form of selenium that can help the immune system. Proprietary source of fresh water reed sedge peat that is a natural chelator which has reduced inflammation in laboratory animals via a patent. A protected source of butyric acid which provides energy to intestinal cells Vitamin C which is a key antioxidant in the body. VevoVitall®, an ultra-pure source of food-grade quality benzoic acid which lowers gut pH and may help with reductions in scours besides a significant improvement in feed efficiency. Based on the numerous specialized ingredients that we have researched and observed positive responses to, we decided to re-evaluate the use of animal plasma in our pig starter program to determine whether it still provided the performance responses we observed years ago. In the plasma-free diets we utilized more cheese protein, higher whey permeate or lactose levels, higher egg antibodies, increased levels of a quality poultry meal and lower levels of soybean meal along with the incorporation of a highly digestible soy protein from Hamlet (in NexGen 8-13 and NexGen 12-17). We compared these to our formulations that contained animal plasma to again determine whether we could develop a new line of pig starters that would replace the immunoglobulins from animal plasma and betaGRO®. The purpose of our trial was to compare a new set of pig starter formulations to pig starter formulations that contained animal plasma. Table 1. Evaluation of Two Formulations for NG 5-10 (Days 0-7), NG 8-13 (Days 7-14) and NG 12-17 (Days 14-21) Plasma √ Avg. Daily Gain, lb .50 .48 Avg. Daily Feed, lb .67 .65 Feed/Gain 1.35 1.38 Cost/lb of gain1, cents 70.87 64.74 Net Return1, $/Pig @ 80 cents/lb 1.09 1.71 KNG; 152 pigs/trt; 23 pens; Avg. Initial Wt., 10.6 lb ¹ Treatment effect (P ≤ .05) In Table 1 are the data comparing the formulations with animal plasma to those with new ingredients replacing the animal plasma. Gain, feed intake and feed efficiency were similar between these two treatments. However, the new diets had a lower cost which resulted in both a significantly lower cost of gain and a greater net return. Net return is defined as the value of gain (valued at 80 cents/lb) minus the feed cost to put on that much gain so having a return of $0.62 in favor of the new formulations was very positive. Note that we had a large number of replications (23) per treatment which provides confidence that the results are valid and thus repeatable. Based on these results, we are introducing a new set of early wean starters that do not contain plasma or betaGRO®. These new formulations contain several high quality ingredients along with all the specialty ingredients we have researched over the years that can enhance performance and the immune status in the pig. This in turn can help producers raise more efficient and profitable pork to feed a growing world.
