Problems solved by technology

[0004] However, there are few reports on the application of Aspergillus oryzae in the feed of small-tailed Han sheep, and its addition amount and effect are not the same.
[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment 1

[0083] Add Aspergillus oryzae PLBS013 of the present invention in the conventional feed of small-tailed Han sheep, and the addition is 325mg / kg.

[0084] After breeding, the pH value of the rumen fluid of Small-tailed Han sheep was measured to be 6.66, the concentration of ammoniacal nitrogen in the rumen fluid was 18.55mg / 100mL, and the concentration of total volatile fatty acids in the rumen fluid was 50.62mmol / L; the degradation rate of dry matter in the rumen was 39.67%, the degradation rate of neutral detergent fiber was 45.90%, and the degradation rate of acid detergent fiber was 41.66%.

Embodiment 2

[0086] Add Aspergillus oryzae PLBS013 of the present invention in the conventional feed of Small-tailed Han sheep, and the addition is 396mg / kg.

[0087] After breeding, the pH value of the rumen fluid of Small Tail Han sheep was measured to be 6.72, the concentration of ammoniacal nitrogen in the rumen fluid was 18.94mg / 100mL, and the concentration of total volatile fatty acids in the rumen fluid was 52.59mmol / L; the degradation rate of dry matter in the rumen was 42.33%, the degradation rate of neutral detergent fiber was 47.51%, and the degradation rate of acid detergent fiber was 40.33%.

Embodiment 3

[0089] Add Aspergillus oryzae PLBS013 of the present invention in the conventional feed of Small-tailed Han sheep, and the addition is 471mg / kg.

[0090] After breeding, the pH value of the rumen fluid of Small-tailed Han sheep was measured to be 6.59, the concentration of ammoniacal nitrogen in the rumen fluid was 17.63mg / 100mL, and the concentration of total volatile fatty acids in the rumen fluid was 52.44mmol / L; the degradation rate of dry matter in the rumen was 40.69%, the degradation rate of neutral detergent fiber was 46.45%, and the degradation rate of acid detergent fiber was 42.69%.

[0091] Since the implementation processes of each embodiment are the same, the specific processes of other embodiments are not listed, and only the above three embodiments with better effects are listed.

Abstract

The invention is applicable to the technical field of microbial breeding, and provides an aspergillus oryzae strain named saccharomyces cerevisiae PLBS013 which has been preserved in China Committee for Culture Collection of Microorganisms under the preservation number of CGMCC NO.16970 since December 17, 2018. The invention further provides application of the saccharomyces cerevisiae PLBS013 in small-tail han sheep feed. The saccharomyces cerevisiae PLBS013 provided by the invention can improve digestive performance of the rumen of the small-tail han sheep, raise degradation rate of fibers inforage grass, effectively adjust physiological functions of rumen of ruminants, increase absorption and utilization rates of the ruminants to nutrients in the feed, and promote growth of the ruminants.

Description

technical field [0001] The invention relates to the technical field of microbial breeding, in particular to a strain of Aspergillus oryzae and its application in feed for small-tailed Han sheep. Background technique [0002] Since the 1980s, the Ministry of Agriculture of my country has actively encouraged and supported the mutton sheep industry, making mutton sheep breeding in my country's agricultural and pastoral areas show a momentum of great development, solving the dilemma of shortage of food resources and increasing demand for animal products in my country, and providing support for the development of animal husbandry. Stable development has laid the foundation. However, there are many problems in the mutton sheep production industry in my country. In order to pursue the production performance of mutton sheep and increase economic benefits, the breeding enterprises choose to add antibiotics and other additives to the feed of mutton sheep to improve the utilization rate...
