Single cell protein (SCP) can be produced from microalgae, yeast, or bacteria and its application in agriculture is on the increase. SCP can be used as alternative protein ingredients to conventional soybean meal or fish meal. In addition, it is of particular interest in animal nutrition since SCP has ability to produce various functional components including amino acids, nucleotides, omega-3 fatty acids, polysaccharides, or antimicrobial peptides. In this sense, SCP as either nutraceuticals or feed ingredients can be utilized to improve the production, welfare and health of animals including companion animals and livestock. The special issue will explore the potential of SCP in global animal industry. Articles related to SCP or its components and their application in animal nutrition (research papers, short communications, reviews) are all welcome.

    Butyrate inhibits the bovine rumen epithelial cell proliferation via downregulation of positive regulators at G0/G1 phase checkpoint

    Abstract Short-chain fatty acids (SCFAs) butyrate promote the postnatal rumen epithelial development and maturation in ruminants. However, molecular mechanisms of effects of butyrate on the bovine rumen epithelial cells (BRECs) proliferation remain elusive. Therefore, purpose of this study was to investigate the effects of butyrate on the expression of genes and proteins at G0/G1 and S phase of BRECs cycle. Our results showed that BRECs treated with butyrate inhibited (P < 0.05) the proliferation of BRECs, relatively to control. Flow cytometric assays revealed that butyrate triggers the BRECs cycle arrest at the G0/G1 phase. qRT-PCR analyses of… More >
