Dissemination of precision farming in Germany: acceptance, adoption, obstacles, knowledge transfer and training activities     

M. Reichardt  C. Jürgens  U. Klöble  J. Hüter  K. Moser 《Precision Agriculture》2009,10(6):525-545

The adoption of precision farming (PF) was studied on the basis of personal interviews conducted at several agricultural exhibitions in Germany. Between 6.65% and 11% of the interviewed farmers used PF. The majority used data collection techniques such as GPS-based area measurement and soil sampling rather than variable rate application techniques such as site-specific sowing and fertilising. Roughly half the farmers interviewed knew about PF. About 7–10% of them intended to start using PF in the future. The results indicated that a large number of farmers did not even know what PF meant. In order to get more insight into this situation, several interviews were conducted with farmers already using PF techniques. A further study in 2005 of PF education in Germany indicated that, especially at vocational and technical schools, the subject was only covered to a small extent although the aim was to give a better coverage in future. At higher education levels, such as at universities and technical colleges, the teaching of PF was clearly better established. In order to promote awareness of PF among farmers, information and teaching materials adapted to the relevant educational levels were developed and tried out at training events. The main topics addressed were parallel tracking systems, site-specific nitrogen fertilising, yield mapping in grain production and the use of PDAs in crop farming. Finally, preliminary survey results are presented showing how knowledge about PF can best lead to its adoption and transfer into daily practice.  相似文献   

Trait values of growth,carcass and meat quality in Wild Boar,Meishan and Pietrain pigs as well as their crossbred generations     

E. Müller  G. Moser  H. Bartenschilager  H. Geldermann 《Zeitschrift für Tierzüchtung und Züchtungsbiologie》2000,117(3):189-202

The genetic diversity between European Wild Boar, Pietrain and Meishan and their crossbred generations are described on the basis of performance traits for growth, carcass composition and meat quality. Using the results of 1333 pigs, the highest growth rates were found in crossbred generations, indicating positive heterosis effects. In carcass composition, high meat content is associated with Pietrain and high fat content with Meishan alleles. Weights of organs were greatest in Wild Boar, the weight of the head was greatest in Meishan. Meat quality and stress resistance parameters point to superior gene effects in Wild Boar and Meishan. Crossbred animals of these genetically diverse pig sources generate the maximum variability for all traits, help to demonstrate the range of values for the specified breeds of pig and allow an efficient analysis of the genes influencing performance traits.  相似文献

Effect of age, weaning and diet on digestive enzyme levels in the piglet   总被引：27，自引：0，他引：27  

M D Lindemann  S G Cornelius  S M el Kandelgy  R L Moser  J E Pettigrew 《Journal of animal science》1986,62(5):1298-1307

Thirty-seven pigs were used to evaluate the effects of age and weaning on the level of protease in the gastric mucosa and trypsin, chymotrypsin, amylase and lipase in the pancreas. There was a positive allometry of the pancreas and gastric mucosa associated with age and with weaning to a solid diet. Increases with age in total activity of chymotrypsin, trypsin, amylase and gastric proteases were due to increases in both tissue weight and enzyme activity per gram of tissue. A general depression in pancreatic enzymatic activities, but not in gastric proteolytic activity, was found during the first week following weaning. Forty pigs were used in a second trial to evaluate the effects of age and weaning diet on the same digestive enzymes. Total activity of all enzymes assayed increased with time postweaning. Increases in total activity of lipase and chymotrypsin were due primarily to increased pancreatic weight postweaning. Amylase, trypsin and gastric protease increases were due both to increased tissue weight and increased activity per gram of tissue. There were no effects of diet on the weight of gastric mucosa or the level of activity of the gastric proteases. Pigs fed a diet containing 20% whey had larger pancreases (P less than .10) at slaughter and a greater, but nonsignificant, mean activity per gram of pancreas for all pancreatic enzymes. It appears that the pig has sufficient pancreatic and gastric enzyme activity so that performance should not be limited, with the possible exception of the period shortly after weaning. However diet digestibility and subsequent pig performance may be more directly related to the extent of release of these enzymes into the intestine and the conditions that exist therein.  相似文献   

Long‐term Effects of Pyrethrin and Cyfluthrin,a Type II Synthetic Pyrethroid,Insecticide Applications on Bull Reproductive Parameters          下载免费PDF全文

JL Stewart  CF Shipley  FA Ireland  VL Jarrell  CL Timlin  DW Shike  TL Felix 《Reproduction in domestic animals》2016,51(5):680-687

The objectives of this study were to determine effects of cyfluthrin and pyrethrin spray products, used in combination with cyfluthrin topical and ear tag applications, on bull reproductive parameters over 18 weeks. Angus or Angus x Simmental bulls were randomly assigned to one of three treatment groups: (i) no exposure to pyrethrins/cyfluthrin (CONT; n = 10), (ii) cyfluthrin ear tag and topical applications (ET; n = 10), or (iii) cyfluthrin ear tag, topical, premise spray and pyrethrin fog spray applications (ET+S; n = 8). Bull body weight was measured every 3 week, and body condition score and scrotal circumference were recorded on weeks 0, 9 and 18. Semen and serum were collected every 3 weeks for sperm evaluation and testosterone measurement, respectively. There was a treatment × week interaction (p < 0.01) for sperm with primary defects; bulls in CONT group had a greater (p = 0.01) percentage of sperm with primary defects than bulls treated with insecticides at week 18. Overall and progressive sperm motility, normal sperm morphology, secondary sperm defects and serum testosterone concentrations changed (p < 0.01) over time in all bulls; however, treatment did not affect (p ≥ 0.13) any of these parameters. There were also no treatment effects (p ≥ 0.08) on bull body weight, body condition score or scrotal circumference. The use of pyrethrin‐ and cyfluthrin‐based insecticides, regardless of application, did not negatively affect reproductive parameters in beef bulls when administered over 18 weeks.  相似文献

Habitat preferences and distribution of the brown rat (Rattus norvegicus Berk.) in the city of Salzburg (Austria): implications for an urban rat management     

Doris Traweger  Rita Travnitzky  Cornelia Moser  Christian Walzer  Guenther Bernatzky 《Journal of pest science》2006,79(3):113-125

The population of Rattus norvegicus was assessed using live traps and hair sampling tubes in 71 discrete patches distributed in the urban area of the city of Salzburg, Austria. R. norvegicus occurred in 35% of the examined habitats and reached a maximum density of 113.12 individuals/km along water banks. The occurrence of rats was strongly influenced by vegetation, habitat modification and man-made impact in the area. The results of this study could be used to support the development of a new, more scientifically based rat management plan in cooperation with the city of Salzburg.  相似文献
