PSXIII-1 - Proof of concept of feeding non-protein nitrogen based special liquid product (StimGain) improve the performance and production in swine and poultry

Abstract: Introduction
Feed is generally the greatest expense for animal production today. Improved feed formulations and new approaches of feeding existing feedstuffs are being explored to increase total protein production. The objective of this study was to determine the efficacy of an energy-based Special Liquid (StimGain) containing non-protein nitrogen (NPN), alcohol, and distiller grain solubles monogastric diets without critically affecting growth and performance.

Methods
Study 1 (Swine grow-finish test): This test included 24 pigs (average purchase weight 42 lb.) per treatment group with three replications were placed for 90 days. The treatments were: 1) Control diet with 16% protein, 2) Protein Check: Control diet with 15% protein, 3) StimGain: same as protein check includes 50lb. of StimGain product per ton feed.

Study 2 (Laying Hen test): This test included 100 pullets per treatment group 10 pullets per cage 10 weeks. At 10 weeks of age, pullets were placed in layer cage 2 birds per cage for 30 weeks. The treatments were: 1) Control diet, 2): Control diet + 50 lb. StimGain product per ton feed. Each group of hens received identical amounts of minerals and vitamins.

Study 3 (Broiler Chicken test): This test included 110 birds per treatment group 10 birds per cage for 42 days. The treatments were: 1) Control diet, 2): Control diet + 50 lb. of StimGain product per ton feed. Each group of hens received identical amounts of minerals and Vitamins.

Differences in growth performance between groups were analyzed for significance using ANOVA then used PostHoc test. Kruskal-Wallis test was done to confirm if there is a significant difference among treatments, continued to normality test by using the Wilcoxon rank sum test to do pairwise comparisons. P≤0.05 was considered significant.

Results
Study 1, from pig study, StimGain improved average feed to gain (Control=3.240, Protein check=3.391, StimGain=3.016), salable meat production (Control= 78.47%, Protein check=80.02%, StimGain=82.22%), lard formation (Control= 14.33%, Protein check=12.39%, StimGain=11.58%).

Study 2, StimGain increased average laying percent of hens (StimGain hens=80.47%, Control hens=79.34%).

Study 3, from broiler chicken study, StimGain improved Feed to Gain (StimGain=2.590, Control=2.911) and salable meat weight (average dressed weight to live weight percentage for StimGain birds=69.93%, Control birds=69.01%).

Conclusions and Discussion
Diet formulated with StimGain in pigs improved feed to gain ratio and improved the efficiency of proteins, rather than more addition of protein to a conventional swine diet. Also, StimGain improved efficiency of metabolism by reducing lard formation and increasing salable meat formation in pigs. StimGain increased average laying percent of hens, and improved feed to gain and salable meat in broilers.
