Although Salmonella is a major problem in poultry food safety, it is believed to be of minor concern for broiler production in regard to animal performance. To determine the effect of Salmonella challenge in broiler chickens, 2880 male Cobb 500 birds derived from a commer­ cial hatchery were evenly distributed over 48 floor pens resulting in 60 birds per pen. Litter was 50% new wood shavings an...

To study the effects of α-galactosidase (α-Gal) supplementation on performance and energy metabolism, 216 Arbor Acres male broilers were placed in 36 cages of 6 birds each and allotted to 4 diets for 42 d, with 0-21 d as starter period and 22-42 d as grower period. The 4 diets were based on corn non-dehulled soybean meal in a 2×2 factorial arrangement, with 2 levels of α-Gal (0 vs. 60 U/kg feed...

2014 If a (d 2014 1)-dimensional surface of a d-dimensional semi-infinite medium has a concentration pS different from the bulk concentration pB one may imagine that percolation is possible even if both pB and pS are below the dand (d 2014 1)-dimensional threshold, respectively. We give simple arguments, partly confirmed by Monte Carlo experiment, why this effect occurs for d = 3 but not for d ...

It is argued, that the sums of reciprocals of all consecutive primes separated by gaps of the length d for d 6 are equal to 4c 2 d Q pjd;p>2 p?1 p?2 , where c 2 = Q p>2 1 ? 1 (p?1) 2. Besides some heuristic arguments leading to this formula, there is also comparison with the results of computer investigation up to 2 42 4:4 10 12. These \experimental" data provides supports for the conjectured f...

Recent studies have shown that naloxone (N), an opioid antagonist, increases concentrations of luteinizing hormone (LH) in the postpartum anestrous beef cow. However, the LH response to N was influenced by the postpartum interval. For example, a significant LH response to 200 mg of N occurred on d 42 but not on d 14 or 28 postpartum. The present study was conducted to determine the effect of di...

ABSTRACT To evaluate the effects of temporary dietary lysine restriction on nursery pigs’ growth performance and its economic viability compared to control diets, 144 piglets (21-d-old) were assigned randomized blocks, with two treatments twelve replicates. The control-lys: level as recommended from 21-32 32-42 days low-lys: 90% control-lys diets. From 42 62 days, all animals received a diet. 2...

This study was designed to investigate the protective effect of curcumin against d-galactose (d-gal)-induced premature ovarian failure (POF) in mice. A mouse POF model was induced by subcutaneous injection of d-gal (200 mg/kg/day) daily for 42 days. Mice in the curcumin group received both d-gal treatment and intraperitoneal injection of curcumin (100 mg/kg/day) for 42 days. Ovarian function, o...
