Effects of Bacillus pumilus on growth performance, serum indexes and muscle development-related gene expression of weanling Jintang black goat
Abstract Antibiotic misuse has been a severe problem in animal husbandry. It is meaningful to replace antibiotics with Bacillus , as feed additives are indeed a research hotspot. Bacillus pumilus plays a certain role in promoting the growth performance and immunological indicators of animals. There are few reports about the function of goat-derived B. pumilus in animals until now. This study aimed to investigate the effects of B. pumilus fsznc-09 on growth performance and immune function of Jintang black goats. B. pumilus -treated group was fed with 1 ml freeze-dried agent of B. pumilus fsznc-09 at a concentration of 10 9 cfu/ml every 2 days. The growth performance, serum biochemical indexes, the expressions of muscle development and metabolism related genes of Jintang black goats were measured after 30 days. The results showed that the average daily gain and average daily feed intake were significantly increased, and feed conversion ratio was significantly decreased. The activities of total superoxide dismutase, alkaline phosphatase, immunoglobulin G and interferon-γ in serum of goats were significantly increased. However, the activity of malondialdehyde in serum was significantly decreased. The diameters and areas in longissimus dorsi fibre and gluteus fibre of goats were significantly decreased, while the densities in gluteus fibre of goats were significantly increased. The expressions of FAS , LPL , PPAR -γ, CAT , MYOD 1, MYOG , MYF 5 and MyHC I in longissimus dorsi and gluteus of goats were significantly improved. The expressions of 1, SREBP -1, MyHC IIb and MyHC IIx in longissimus dorsi and gluteus of goats were significantly increased. The expressions of FN 1 in longissimus dorsi and MyHC IIa in gluteus of goats were significantly decreased. In conclusion, B. pumilus fsznc-09 can effectively improve the growth performance, immunological indicators and the expressions of muscle development and metabolism related genes of Jintang black goat.
期刊介绍：
Beneficial Microbes is a peer-reviewed scientific journal with a specific area of focus: the promotion of the science of microbes beneficial to the health and wellbeing of man and animal. The journal contains original research papers and critical reviews in all areas dealing with beneficial microbes in both the small and large intestine, together with opinions, a calendar of forthcoming beneficial microbes-related events and book reviews. The journal takes a multidisciplinary approach and focuses on a broad spectrum of issues, including safety aspects of pro- & prebiotics, regulatory aspects, mechanisms of action, health benefits for the host, optimal production processes, screening methods, (meta)genomics, proteomics and metabolomics, host and bacterial physiology, application, and role in health and disease in man and animal. Beneficial Microbes is intended to serve the needs of researchers and professionals from the scientific community and industry, as well as those of policy makers and regulators.
The journal will have five major sections:
* Food, nutrition and health
* Animal nutrition
* Processing and application
* Regulatory & safety aspects
* Medical & health applications
In these sections, topics dealt with by Beneficial Microbes include:
* Worldwide safety and regulatory issues
* Human and animal nutrition and health effects
* Latest discoveries in mechanistic studies and screening methods to unravel mode of action
* Host physiology related to allergy, inflammation, obesity, etc.
* Trends in application of (meta)genomics, proteomics and metabolomics
* New developments in how processing optimizes pro- & prebiotics for application
* Bacterial physiology related to health benefits
