Dietary Bacillus subtilis C-3102 Spores for Laying Hens: Egg Shell Quality and Brown Egg Color Score
Published:August 30, 2007
Summary
Bacillus subtilis C-3102 spores are receiving increased attention as dietary direct-fed microbial (probiotic) performance enhancers for laying hens and breeders because as a feed supplement they typically are effective for improving egg shell thickness and brown egg shell color (in brown-egg strains), have high survivability through steam pelleting, and are economical (B.s. C-3102; CALSPORIN®, Ca...
Nicarbazin main for the prevention of chicken cercal coccidiosis (Imperia) and the reactor type, giant, poisoned, E.brunetti (intestinal coccidiosis). According to tests, medication within 48h after infection coccidiosis, coccidia can effectively inhibit the development, if the drug later than 72h, the effect is significantly reduced
Why some paragraph under the heading of (broiler breeder) were pasted? I had roughly read before, interesting about the relationship b/t egg shell color intensity or uniformity and hatchability. Now I can not recall, I want to see again and please do something for that. Does it mean that the facts mentioned before are wrong? Please explain.
Hi. The text in the broiler breeder section is correct. What's missing [actually there but difficult to read in the colored section] is the Conclusion section. So it is included here:
Conclusion. Spores of B.s. subtilis C-3102 have proven useful in the diets of laying hens to improve egg shell thickness or breaking strength and to increase brown egg color score of brown-egg strains compared to results for unsupplemented hens. When added to the diets of broiler breeder hens, B.s. subtilis C-3102 spores increased cumulative fertile egg production
compared to results for hens fed diets containing an antibiotic. The proliferation of Lacto-
bacillus species in the intestinal tract of B.s. subtilis C-3102 supplemented hens helps decrease the counts of intestinal pathogens such as Salmonella, E. coli, Campylobacter, and
Clostridium perfringens based on fresh fecal microbial profiles. It is generally accepted that
the presence of relatively low or normal levels of Clostridium perfringens or other pathogens
in laying hens or breeders can spike up as a result of severe stressors such as high stocking density, disease challenge, feed and/or water deprivation, and so on, and cause morbidity,
performance declines, or above-normal mortality.
