Effect of Log10® Pre-Liminate™ Probiotic Blends on Palatability of Dry Dog Food

Summary

Pet food manufacturers often include probiotics in their formulas for a variety of reasons like digestive health and stool quality. Additionally, with the Pre-Liminate™ probiotic blends from Log10, LLC®, manufacturers can now prevent and eliminate food-borne pathogens like Salmonella spp. and Listeria spp.

The possible negative effects of a new additive in dog food on palatability is a major concern to manufacturers. Two experiments were conducted on the effects of topically-applied Log10® Pre-Liminate™ probiotics on palatability of dry commercial kibble. The probiotic carrier in Expt. 1 was dried sweet potato and in Expt. 2 it was corn starch. In both experiments, 20 individually-housed dogs were offered both treated and untreated kibble in separate bowls. There were no differences between pro-biotic treatments in any measure of palatability (first approach, first consumed, or daily consumption).

Procedures

In two separate experiments, palatability of untreated commercial dry kibble was compared to that of the same kibble treated with Log10® Pre-Liminate™. Each probiotic blend consisted of a food grade carrier and proprietary blends of Lactobacillus spp. and Bifidobacterium spp.
Probiotic blends were applied topically to kibble by mechanical mixing for 10 minutes. In both experiments, the application rate greatly exceeded that recommended for controlling pathogens in practice.

In each experiment, 20 dogs were housed individually in a commercial kennel and offered untreated and treated kibble in separate bowls simultaneously for two days. Kibble positions in bowls were inverted on the second day. Quantities offered were in excess of voluntary consumption.

Expt. 1: Sweet Potato Carrier, Pre-Liminate™ D2.2:

  • Average dog weight was 30 lb. Each dog was offered 0.88 lb. of each type of diet.

Expt. 2: Corn Starch Carrier, Pre-Liminate™ D3.1:

  • Average dog weight was 55 lb. Each dog was offered 1.8 lb. of each type of diet.

Results

There were no statistically significant differences between treatments in either experiment in a) first diet approached, b) first diet consumed, or c) daily diet consumption (Tables 1 and 2).

Conclusions

Topical application of Log10® Pre-Liminate™ probiotic blends based on sweet potato (D2.2) or corn starch (D3.1) had no negative effects on the palatability of dry kibble to dogs. Even though these blends were applied at rates greater than recommended, there were no differences in first approach, first consumed, or daily consumption. Pre-Liminate™ blends may be applied topically in manufacturing dry dog food kibbles without concern about a negative effect on palatability of the dog food.
