Application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. Therefore, scientists are searching for alternatives to antibiotics nowadays. Medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. In this paper, the benefits of...

BACKGROUND: Growth promoters are chemical and biologicalsubstances that are added to livestock food with the aimto improve the growth of chickens in fattening and the utilizationof food, and in this way achieve better production and financialresults. OBJECTIVES:An experiment was conducted to evaluatethe effects of enzyme complex, probiotic, and their combinationon performance of broilers fed a ...

Stationary phase is the stage when growth ceases but cells remain metabolically active. Several physical and molecular changes take place during this stage that makes them interesting to explore. The characteristic proteins synthesized in the stationary phase are indispensable as they confer viability to the bacteria. Detailed knowledge of these proteins and the genes synthesizing them is requi...

The use of antimicrobials as growth promoters and disease prevention is being constantly reduced in several animal production systems, including the swine industry. Therefore, this study aimed to evaluate effectiveness using acidifiers control Salmonella Typhimurium 65-day-old pigs by detecting pathogen organs at euthanasia. For this, 24 piglets were divided into two experimental groups consist...

Cell-specific expression of tissue factor (TF) in vivo is consistent with its primary role in hemostasis. In addition, TF expression is induced in cultured cells by a variety of agents, including serum and growth factors, which define the TF gene as a "primary response" gene. In this study we examined the signaling pathways and cis-acting regulatory elements required for induction of TF gene ex...

As a global health problem, antimicrobial resistance (AMR) crosses national borders, leading UN (United Nations) multilateral agencies to call for all countries improve the stewardship of antibiotics in humans and animals. South American have changed their regulations regarding antibiotic use livestock production. This literature review examines how far five largest meat-producing America (Arge...

Senescence, a state of stable growth arrest, plays an important role in ageing and age-related diseases vivo. Although the INK4/ARF locus is known to be essential for senescence programmes, key regulators driving p16 ARF transcription remain largely underexplored. Using siRNA screening modulators p16/pRB ARF/p53/p21 pathways deeply senescent human mammary epithelial cells (DS HMECs) fibroblasts...
