A field enquiry mentioned the potential positive impact of a feed restriction on the health of young rabbits, but no objective information relates the intake to digestive health. The effects of a post-weaning feed restriction strategy were thus studied on digestive health and growth and carcass parameters of the growing rabbit, using a monofactorial design that produces a quantitative linear re...

A 3 to 4 week feed restriction of about 20% to 25% of the free intake is widely applied in rabbit breeding systems to reduce post-weaning digestive disorders. However, a short intensive feed restriction is described in few studies and can be beneficial for growing rabbits due to a longer re-alimentation period. The aim of this study was to evaluate the effect of ad libitum (AL) and two restrict...

In 2003, a feed-borne outbreak of Salmonella Cubana occurred in Sweden as a result of contamination in a feed plant. Salmonella Cubana was detected in 49 out of 77 pig farms having received possibly contaminated feed. In this study, potential risk factors for farms being salmonella positive were examined, and a survival analysis was performed to investigate risk factors affecting the restrictio...

This study was conducted to evaluate the effect of feed restriction on body weight, body weight gain, feed intake, and feed conversion ratio and carcass traits of broilers. Two hundred and forty one day old Hubbard broiler chicks were randomly distributed into five treatments. Each treatment included six replicates of 8 birds each. The five treatments were as follows: T1( birds were fed continu...

background: liver fatty acid-binding protein (l-fabp) is the main cytosolic binding site for long chain fatty acids in hepatocytes. fabps enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. objectives: the aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

A total of 192 Hyplus rabbits (male and female ratio 1:1) of weaning age 35 d were randomly divided into three experimental groups (n=64 each), group 1 was fed ad libitum (control), group 2 (R50) was restricted from 42 to 49 d of age (50 g/d/rabbit), and group 3 (R65) was restricted from 42 to 49 d of age (65 g/d/rabbit). After the restriction time, all the groups were back to ad libitum feedin...

Post-weaning feed restriction strategies have proved to reduce mortality and morbidity, but result in decreased growth and lower slaughter yield. To compensate for those deleterious effects without negatively impacting the health parameters, we have studied the possibility of increasing the dietary energy level of the feed. Four treatments differing in dietary digestible energy content (“low” e...

Forty-five Hisex commercial layers and forty-five local Saudi breed layers were used to determine the acceptable limit of short-term water restriction in the late phase of production, when the problem of high feed and water consumption is expected. The experiment was performed under hot and arid environmental conditions when the layers were at fifty weeks of age. Layers from each breed were ran...

Optimization of a serotype-selective, small-molecule inhibitor of botulinum neurotoxin serotype A (BoNTA) endopeptidase is a formidable challenge because the enzyme-substrate interface is unusually large and the endopeptidase itself is a large, zincbinding protein with a complex fold that is difficult to simulate computationally. We conducted multiple molecular dynamics simulations of the endop...
