An experiment was carriedout to investigate the effect of dietary energy level levels on feed intake modern broiler chickens during growth period. A total 160 Ross chicks (mixed-sex) in a completely randomized design with 4 treatments and replicates (10 birds) were used. The fed from 11 24 days age treatments, including grower diets 2800, 2900, 3000, 3100 kcal/kg ME constant nutrient ratios. Al...

Sixteen years of archived tufted apple bud moth, Platynota idaeusalis (Walker), trap capture data were compared with archived fruit injury data collected at the Penn State University Fruit Research and Extension Center to define the relationship of trap capture to fruit injury. Pheromone trap capture until 15 June was the best predictor of fruit injury at harvest. Using the regression equation ...

Increasing global food demand, accompanied by the limited number of expert growers, brings need for more sustainable and efficient horticulture. The controlled environment greenhouses enable data collection precise control. For optimally controlling greenhouse climate, a grower not only looks at crop production, but rather aims maximising profit. However this is complex, long term optimisation ...

Physical castration is a common management practice on commercial swine farms in the U.S. to reduce the incidence of boar taint and aggressive behavior. One alternative to physical castration (PC) is to immunologically castrate (IC) male pigs by blocking gonadotropin releasing factor (GnRF), thereby reducing levels of LH, FSH, testosterone and androstenone. The objectives of this study were to ...

Commercial Australian White turkey poults, kept in small pens, were fed commercial diets until 8 weeks. Poults were then fed either 20 per cent dietary protein, with or without added lysine, or 24 per cent dietary protein, each with a metabolizable energy content of either 11.5 or 12.75 MJ/kg. The poults fed on the 24 per cent protein diet were heavier than those on the 20 per cent protein diet...
