Escherichia coli is a common cause of postweaning diarrhea in swine, but usually does not affect grower-finisher pigs. Eleven-week-old grower pigs presented with an acute and severe watery diarrhea, initially considered to be transmissible gastroenteritis. Diagnostic submissions showed the causative agent to be an F18positive E coli producing shiga-like toxin. No pigs developed neurological sig...

This study was conducted to compare ileal digestibility of calcium, dry matter and ash, growth performance, gut characteristics, bone parameters and retention of calcium in broiler chickens fed diets containing different calcium sources. A total of 96 commercial Ross 308 broiler chickens were allocated to three experimental diets. The experimental diets included a diet containing inorganic calc...

This experiment was conducted to evaluate the effects of saturated and unsaturated fats in starter and grower feeds on performance and carcass parts of broilers. In this experiment 288 day old broiler chicks (Ross308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 12 chicks in each replicate. The experimental groups included: T1) control gro...

Sixteen castrated male pigs (averaging 21.2 +/- 4.9 kg) were used in two trials to investigate the effect of dietary amino acid content during the grower phase on growth performance and N balance. In each trial, pigs were assigned randomly to corn-soybean meal grower diets formulated to contain 5.0 or 11.0 g lysine/kg (as-fed basis). Common Finisher 1 and 2 diets were offered when pigs reached ...

A trial was conducted to determine the effect of low-protein diets with constant ME:CP ratio on performance and carcass characteristics of broilers from 1 to 35 d of age. Four experimental diets were formulated to have 4 levels of CP and ME, respectively, in each phase: 23, 22, 21, and 20% CP with 3,036, 2,904, 2,772, and 2,640 kcal/kg in the starter phase (1 to 10 d); 22, 21, 20, and 19% CP wi...

This experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (PBPM) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. Three samples of PBPM produced in Ardabil province located in northwest of Iran, were provided during one month sampling peri...

Chicory (Chicorum intybus) is becoming popular as a warm-season forage for ruminant livestock in the United States. A study was conducted with weaned crossbred meat goats to elucidate how growing / finishing meat goats grazing Joy chicory pasture respond to supplementation with varying levels of dietary protein. Thirty 6 weaned crossbred kids (26 ± 3 kg) were blocked by body weight and genotype...

Over a 6-month period, the mean mortality risk (based on 393 operations participating in the United States National Animal Health Monitoring System 1995 National Swine Study, and representing operations with > or = 300 market hogs in 16 states), was 2.3 +/- 0.2% in the grower/finisher production phase (where figures after the +/- represent the standard error of the estimate). Mortality > or = 4...

J Agric Entomol 15(4): 377-386 (October 1998) ABSTRACT We conducted a study to optimize the deployment of our controlled pheromone release system called metered semiochemical timed release system (MSTRSTM) and to measure its impact on male blackheaded fireworm, Rhopobota naevana (Hubner) (Lepidoptera: Tortricidae) The deployment pattern and pheromone emission rate of the M S T R S devices were ...

Three experiments were conducted to determine the digestible lysine requirement of starter (6 kg BW initially) and of grower (21 kg BW initially) pigs. Experiment 1 used 294 starter pigs and lasted 28 d; Exp. 2 used 182 grower pigs and lasted 35 d. Protein and total lysine contents of the basal corn-peanut meal diets were 20 and .8% for Exp. 1 and 16 and .54% for Exp. 2. Basal diets were fortif...
