Five hundred forty crossbred pigs were utilized in four trials (10 replications) at two stations to determine the separate and interacting effects of decreasing floor space allowance with or without the addition of virginiamycin to the diet on performance of growing-finishing pigs. Pigs were allowed .37, .33 or .28 m2/pig during the growing phase (23 to 55 kg) and .74, .66, .56 m2/pig during th...

OBJECTIVES Owing to the spread of antibiotic resistance among human infectious agents, there is a need to research antibiotic alternatives for use in animal agricultural systems. Antibiotic-free broiler chicken production systems are known to suffer from frequent outbreaks of necrotic enteritis due in part to pathogenic type A Clostridium perfringens. Hop (Humulus lupulus) bitter acids are know...

The aim of this study was to compare the effect of toothpastes containing TiF(4), NaF, and SnF(2) on tooth erosion-abrasion. Bovine enamel and dentin specimens were distributed into 10 groups (n = 12): experimental placebo toothpaste (no F); NaF (1450 ppm F); TiF(4) (1450 ppm F); SnF(2) (1450 ppm F); SnF(2) (1100 ppm F) + NaF (350 ppm F); TiF(4) (1100 ppm F) + NaF (350 ppm F); commercial toothp...

Effect of ethanolic extract of propolis, royal jelly, honey and bee pollen in comparison with virginiamycin (as growth promoter antibiotic) as regards the performance and immune system of Japanese quail were assessed. We used 256 mixed-sex quail chicks in a completely randomized design by eight treatments, including control, ethanolic extract of propolis 1000 (PE1) and 5000 (PE2) mg kg-1</...

OBJECTIVE Nutrition success in short bowel syndrome (SBS) depends on the intake nutrients and the intestinal absorption capacity. An evaluation of energy expenditure and oxidation of substrate can be obtained with indirect calorimetry by measuring O(2) and CO(2) in the respiration. Elevated colonic fermentation can occur in SBS, producing H(2) and CO(2), which can also be eliminated through res...

For preventing erosive wear in dentine, coating with adhesives has been suggested as an alternative to fluoridation. However, clinical studies have revealed limited efficacy. As there is first evidence that Sn(2+) increases bond strength of the adhesive Clearfil SE (Kuraray), the aim of the present study was to investigate whether pre-treatment with different Sn(2+)/F(-) solutions improves the ...

Acute laminitis can be induced experimentally in horses by the administration of carbohydrate, resulting in fermentation within the cecum and ischemia-reperfusion of the digits. The products of fermentation that trigger acute laminitis are as yet unknown; however, compounds such as amines might play a role due to their potential vasoactive properties. The objectives of this study were to quanti...
