Lactic acid bacteria and Bacillus bifidus are well-known probiotics used as alternatives to conventional pharmacotherapy in infectious diseases. Butyric (butyrate) such Clostridium butyricum also useful but have been rarely studied. To identify new butyrate-producing bacterial species, we examined the production of organic acids, including butyrate, tertium C. butyricum. Protein BLAST (BLASTP) searches for butyrate kinase (BUK) proteins genomes identified two proteins. confirm their presence...

Preweaning diet is known to affect rumen tissue appearance at the gross level. The objectives of this experiment were investigate effects different preweaning diets on growth and development epithelium putative epithelial stem progenitor cell measurements gene levels. Neonatal Holstein bull calves (n = 11) individually housed randomly assigned 1 2 diets. milk replacer only (MRO; n 5) or with starter (MRS; 6). Diets isoenergetic (3.87 ± 0.06 Mcal metabolizable energy per day) isonitrogenous...

Lactic acid bacteria and bacillus bifidus are well-known as probiotics used alternative drugs confronting infectious disease, however, butyric (butyrate) such Clostridium butyricum also useful but little-known in any part of the world. To discover a new species producing butyrate, we examined production organic including butyrate tertium C. butyricum. Protein BLAST (BLASTP) searches on Butyrate kinase (BUK) proteins genomes have identified 2 proteins. confirm their presence genome tertium,...

Abstract Estradiol administration increases mammary parenchyma growth and can increase the mass of fat pad (MFP) in calves. affect fatty acid metabolism, but it is unknown how estradiol affects profile MFP if these effects are consistent across adipose stores. The objective this investigation was to determine profiles were affected by response tissue type specific. Holstein heifer calves reared on a common diet administered 12 daily injections prior euthanasia at 82 days age. Injections...

Abstract Growth of the bovine mammary gland is influenced by estradiol during a heifer’s life. The objective this study was to determine effect administration on two different parenchymal tissue regions and quantify response in cellular proliferation between treatments regions. Treatments were administered daily 12 days prior euthanasia at 82 age. Holstein heifer calves (n = 12) divided amongst 3 treatments, control 4, CON), short term SHORT), long LONG). CON corn oil injections while SHORT...

Abstract This research communication reports the relative abundance of fatty acids in mammary fat pad (MFP) and subcutaneous adipose (SCA) tissues for Holstein heifer calves receiving 0, 3, or 12 daily injections estradiol immediately prior to tissue collection. The objective this study was determine if MFP SCA acid profiles were affected by administration such a response differs between depots. Twelve reared on common diet administered euthanasia. Injections either corn oil ( n = 4; CON), 9...
