For the past two years, Applicant, with the assistance of the assignee of this invention, has developed a microbial feed additive for the swine industry. Although the field research has been conducted with pigs, applicant anticipates that the additive of this invention may be extended to include chickens and turkeys (monogastrics). The feed additive of this invention comprises three main components, lactic acid bacteria (LAB), silicate such as bentonite, calcium bentonite, sodium bentonite, perlite, verxite, zeolite montmorillonite, and yeast. The yeast of this invention may be either a live or a dead yeast. In the animal feed additive of this invention, the lactic acid bacteria is selected from the group of Bacillus subtilis, Bifidobacterium adolescentis, Bifidobacterium animalis, Bifidobacterium bifudum, Bifidobacterium infantis, Bifidobacterium longum, Bifidobacterium thermophilum, Lactobacillus acidophilus, Lactobacillus agilis, Lactobacillus alactosus, Lactobacillus alimentarius, Lactobacillus amylophilus, Lactobacillus amylovorans, Lactobacillus amylovorus, Lactobacillus animalis, Lactobacillus batatas, Lactobacillus bavaricus, Lactobacillus bifermentans, Lactobacillus bifidus, Lactobacillus brevis, Lactobacillus buchnerii, Lactobacillus bulgaricus, Lactobacillus catenaforme, Lactobacillus casei, Lactobacillus cellobiosus, Lactobacillus collinoides, Lactobacillus confusus, Lactobacillus coprophilus, Lactobacillus coryniformis, Lactobacillus corynoides, Lactobacillus crispatus, Lactobacillus curvatus, Lactobacillus delbrueckii, Lactobacillus desidiosus, Lactobacillus divergens, Lactobacillus enterii, Lactobacillus farciminis, Lactobacillus fermentum, Lactobacillus frigidus, Lactobacillus fructivorans, Lactobacillus fructosus, Lactobacillus gasseri, Lactobacillus halotolerans, Lactobacillus helveticus, Lactobacillus heterohiochii, Lactobacillus hilgardii, Lactobacillus hordniae, Lactobacillus inulinus, Lactobacillus jensenii, Lactobacillus jugurti, Lactobacillus kandleri, Lactobacillus kefir, Lactobacillus lactis, Lactobacillus leichmannii, Lactobacillus lindneri, Lactobacillus malefermentans, Lactobacillus mali, Lactobacillus maltaromicus, Lactobacillus minor, Lactobacillus minutus, Lactobacillus mobilis, Lactobacillus murinus, Lactobacillus pentosus, Lactobacillus plantarum, Lactobacillus pseudoplantarum, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus rogosae, Lactobacillus tolerans, Lactobacillus torquens, Lactobacillus ruminis, Lactobacillus sake, Lactobacillus salivarius, Lactobacillus sanfrancisco, Lactobacillus sharpeae, Lactobacillus trichodes, Lactobacillus vaccinostercus, Lactobacillus viridescens, Lactobacillus vitulinus, Lactobacillus xylosus, Lactobacillus yamanashiensis, Lactobacillus zeae, Pediococcus acidlactici, Pediococcus pentosaceus, Streptococcus cremoris, Streptococcus discetylactis, Streptococcus faecium, Streptococcus intermedius, Streptococcus lactis, and Streptococcus thermophilus. The amount of lactic acid bacteria added to the animal feed ration ranges in the amount of 100 to 100,000,000 cfu/g, the silicate comprises 0.0005 to 5.0% of the total mixed ration, while the yeast comprises 0.0025 to 2.5% of the total mixed ration. In the preferred formula, the lactic acid bacteria is added to the animal feed in the amount of 130,000 cfu/g, the silicate comprises 0.05% of the total mixed ration and the yeast culture comprises 0.0025% of the total mixed ration.
The silicate of the animal feed additive of this invention may be bentonite, calcium bentonite, sodium bentonite, perlite, verxite, or zeolite. Bentonite is a naturally occurring mineral consisting primarily of the tri-layered aluminum silicate, montmorillonite. It may contain calcium or sodium as the predominant available or exchange ion. Bentonite is normally used or intended for use in non-medicated animal feed as an anti-caking agent or a pelleting aid. Although bentonite was used in the trials set forth below, it is believed that sodium bentonite or calcium bentonite are also satisfactory in the feed additive of this invention.
Hereinbelow are Tables 1-7 which set forth the results of the exhaustive tests conducted by applicant and the assignee wherein the feed additive of this invention is identified as Formula 1050.
As seen in Table 1, the use of the feed additive of this invention results in an improvement in the number of piglets born alive in the amount of 5.9%.
Table 2 illustrates that the use of the feed additive of this invention results in an improvement in the gain per pig in the amount of 2.5% and results in a reduction in the mortality rate of the pigs in the amount of 59.1%.
Table 3 illustrates that the effect of feeding the animal feed additive of this invention with reduced dietary protein on growth performance in growing-finishing pigs increases the gain per pig in the amount of 15.9%.
Table 4 illustrates an improved gain per pig in the amount of 7.5% while Table 5 illustrates an improved gain per pig in the amount of 6.7%.
Table 6 illustrates the effect of feeding Lincomix+Superzyme on growth performance of growing pigs. It can be seen from Table 6 that the animal feed additive of this invention provides a dramatic improvement.
Table 7 also illustrates the results of the effect of feeding the feed additive of this invention with respect to finishing pigs.
It is clear from the above tables that the use of the feed additive of this invention in a feed ration results in: (1) more piglets born alive; (2) reduced mortality in “nursery” pigs; (3) improved growth performance in “pregrower”, “growing” and “finishing” pigs; (4) improved utilization of dietary protein in “pregrower” and “finishing” pigs; and (5) improved growth performance in “stressed” pigs.
The additive utilized in the feeding trials of Tables 1-7 above consisted of the ingredients set forth in Table 8 hereinbelow. The amounts set forth in Table 8 are the amounts in the total mixed ration.
While Table 8 sets forth the preferred amounts of the ingredients, Table 9 hereinbelow sets forth the permissible ranges of those ingredients.
It can therefore be seen that the microbial feed additive of this invention represents a significant improvement in the art. Thus it can be seen that the feed additive of this invention accomplishes at least all of its stated objectives.
