BACKGROUND Delaying pigs from advancing through the production stages could have a negative impact on their health and performance. The objective of this study was to investigate the possible implications of delaying pigs from the normal production flow on pig health and performance in a farrow-to-finish commercial farm with a self-declared All-In/All-Out (AIAO) management. RESULTS Three flow...

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...

The study was based on data collected during 5 yr (2003-2007) and was aimed at assessing the effects of the month, slaughter house of destination (differing for stocking density, openings, brightness, and cooling device types), length of the journey, and temperature-humidity index (THI) on mortality of heavy slaughter pigs (approximately 160 kg live weight) during transport and lairage. Data we...

This study was carried out to determine the effects of supplementation ground fennel quail rations on egg production, slaughter, intestinal parasites, and semen quality. For this purpose, 48 female 24 male quails were used in study. The experimental groups consisted control group with basal feed + 0% fennel, GF1, GF2, GF4 fennel-supplemented by 1%, 2%, 4% respectively, also each designed pairs....

The objective of this study was to evaluate whether altering the timing of the secondary anti-gonadotropin-releasing factor (GnRF) immunization closer to slaughter in male finishing pigs would reduce the increase in P2 fat depth (6.5 cm from the midline over the last rib), while still limiting the incidence of boar taint. Entire male pigs are immunized against GnRF to reduce the concentration o...

Limousin-cross steers (n=135; 258+/-26 kg) were used to compare forage vs grain feeding on carcass composition and palatability attributes of beef when time on feed was controlled. Diets included a 95% alfalfa silage ration (AS) or a 68% high-moisture corn, 25% alfalfa silage ration (HMC). These were incorporated into six treatments to allow comparisons of end points based on similar days on fe...

The aim of the present experiment was to determine whether age, live weight, or a combination of both, was the most important factor influencing fat 5 alpha-androstenone levels in male pigs. Three groups of 50 boars each were fed either on a liberal plane of nutrition (CTRL group) or were restricted (SW and SA groups). Fat 5 alpha-androstenone was measured three times in each pig (on biopsies a...
