Small-scale farmers in developing countries use hazardous pesticides taking few or no safety measures. Farmer field schools (FFSs) teaching integrated pest management (IPM) have been shown to reduce pesticide use among trained farmers. This cross-sectional study compares pesticide-related knowledge, attitude, practice (KAP), potential exposure, and self-reported poisoning symptoms among 35 FFS ...

Subclinical inflammatory activity may be one of the factors which influences the variable natural history of farmers' lung. Serum lysozyme (LYS) and angiotensin converting enzyme (ACE) have been measured in 52 farmers with a previous history of farmers' lung and in 51 healthy control farmers. The group with farmers' lung assessed during the winter, although having had no recent acute symptoms, ...

The objective of this experiment was to compare the effects of belt grill and Open Hearth electric broiler cookery on palatability and cooking traits of longissimus steaks. The longissimus thoracis from carcasses of grain-fed steers or heifers was used. Duplicate measurements were made for Warner-Bratzler shear force at 3 and at 14 d after slaughter (n = 180) and trained sensory evaluation at 1...

DENEV, S. A., 2006. Effect of different growth promoters on the cecal microflora and performance of broiler chickens. Bulg. J. Agric. Sci., 12: 461-474 The objective of this study was an evaluation of the effects of different growth promoters: probiotic Lacto-Sacc® (Alltech, Inc. USA), nutritive premix Pharmastim and nutritive antibiotic Avilamycin on the cecal microflora and performance of bro...

Broiler Performance Efciency Factor (BPEF) isa smart and comprehensive indicator to assessthe performance of broilers. Batch wise datawere recorded from commercial broiler farmslocated in the hot and cold climatic zones inindustrial broiler production areas and analyzedfor its mean BPEF performance. The mean oorspace allowance, stocking density recorded in ...

Three-week-old broiler chicks and 1-yr-old Leghorn cocks were used to determine the effect of beta-glucanase addition (experimental product from Trichoderma longibrachiatum) to a 60% barley-based diet on rate of feed passage, transit time, and mean retention time. Fecal chromium oxide content was used to calculate cumulated and noncumulated excretion data. A Hill equation was chosen to test the...

Recent research to define a measure of chick quality has evaluated the effects of incubation conditions, breeder age and genotype on progeny growth and survival. Nutritional research has focused on defining the optimum concentration of maternal dietary nutrients for progeny growth, mortality and immune status. There is a research requirement to bring these two areas together to better understan...

A study was undertaken to test the effect of 2 commercially available probiotics on the production efficiency of broiler chickens hatched from the same breeder flock at 3 different ages (28, 43, and 57 wk). At each of the 3 breeder flock ages, 1,600 broiler chickens were hatched and randomly allocated to 1 of 4 treatments: 1) no probiotics (control), 2) probiotic 1 administered in the drinking ...

Since meat from poultry colonized with Campylobacter spp. is a major cause of bacterial gastroenteritis, human exposure should be reduced by, among other things, prevention of colonization of broiler flocks. To obtain more insight into possible sources of introduction of Campylobacter into broiler flocks, it is essential to estimate the moment that the first bird in a flock is colonized. If the...
