This paper summarises six studies undertaken by the Sheep CRC to elucidate certain aspects of confinement feeding of sheep. A review of confinement feeding highlighted the variability of growth rate and feed conversion of sheep and revealed that little is known about the use of sorghum for feeding sheep. The review indicated that the main factors responsible for variation of growth rate and fee...
OBJECTIVES The impact of agricultural use of antimicrobials on the present and future efficacy of therapeutic drugs in human medicine is a growing public concern. Quinupristin/dalfopristin has been approved to treat human disease caused by vancomycin-resistant Enterococcus faecium and is related to virginiamycin, a streptogramin complex that has long been used in USA agriculture poultry product...
Intensifying concerns about the use of antimicrobials in meat and poultry production has enhanced interest in the application of prebiotics, probiotics and enzymes to enhance growth and prevent disease in food animals. Growth-promoting antibiotics enhance growth of animals by reducing the load of bacteria in the intestine, by reducing colonization by intestinal pathogens or by enhancing the gro...
to evaluate the efficiency of nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. the experimental treatments included: 1) control (no additives)...
مساله تغذیه طیور یکی از تنگناهای توسعه مرغداری در کشور ما به شمار میرود. کمبود مواد اولیه و محدود بودن تولید آن در کشور سبب گردیده است که هر ساله مقدار زیادی مواد اولیه از خارج با پرداخت مقادیر قابل توجهی از ثروت ملی کشور وارد شود. ذرت در جیره های غذای طیور در دنیا و در ایران به عنوان تامین کنندهاصلی منبع انرژی مورد استفاده قرار میگیرد. خوراک همچنان بیشترین هزینه پرورش طیور را به خود اختصاص داد...
Abstract Virginiamycin (VM) is an antibiotic that possesses antimicrobial properties due to its ability block protein synthase in Gram-positive bacteria. It reduces lactic acidosis and the incidence of liver abscesses. Animal growth development brought about because improved ruminal health, animal health welfare. This study evaluated continuous or intermittent provision VM during growing finish...
introduction antibiotic feed additives have long been used as growth promoters in poultry nutrition. however, concern has been expressed about the potential development of antibiotic resistant bacteria (25). consequently, the animal feed industry, exposed to increasing consumer pressure to reduce the use of antibiotic growth promoters in poultry diets, has to find alternative feed additives. ma...
the present experiment was carried out to determine the effects of antibiotic growth promoters, blend of medicinal plants, prebiotic and organic acid on performance and nutrients apparent digestibility in a six week period, using one hundred ninety two one- day- old broiler chicks (cobb 500) on a randomized complete block design experiment with six treatments consisting of 4 replications and ...
