Studies on the Prevalence and Control of Parasitic Helminths in Natural Laying Hens

One societal trend that has been gaining much traction and popularity since the 21st century began is “organic” and/or “natural” food products. In 1999, the global market accounted for $15.2 billion dollars worth of organic food and drink, compared to the market in 2014 where we consumed$80 billion dollars worth (Willer et. al, 2016). With “natural” production of food animals however, “natural” parasite transmission may be a consequence. To that end, this experiment examines the prevalence of helminths in 110 “natural” laying hens from three regional farms and the efficacies of fenbendazole, piperazine, and levamisole on what should be naive helminths. The 3 regional farms were: Vital Farms in Evansville, Arkansas; Vital Farms in Westville, Oklahoma; and Arkansas Egg Company in Summers, Arkansas. Birds from each location were administered fenbendazole, levamisole, or piperazine and one additional group served as control. After 1 week the hens were sacrificed and processed for helminth qualification and quantification. The helminths that we collected and identified from the intestinal tracts were Ascaridia galli, Heterakis gallinarum, and Raillietina cesticillus. The results show that there were far more helminths in the control group than the other treatment groups. The results also show that there were far more H. gallinarum than A. galli in the intestines of these chickens. Overall these anthelmintics used could be successful in controlling “naïve” A. galli but could not be nearly successful in controlling “naïve” H. gallinarum in these “natural” laying hens

Learning from Analysis of Japanese EFL Texts

Japan has a long tradition of teaching English as a foreign language (EFL). A common feature of EFL courses is reliance on specific textbooks as a basis for graded teaching, and periods in Japanese EFL history are marked by the introduction of different textbook series. These sets of textbooks share the common goal of taking students from beginners through to able English language users, so one would expect to find common characteristics across such series. As part of an on-going research programme in which Japanese EFL textbooks from different historical periods are compared and contrasted, we have recently focussed our efforts on using textual analysis tools to highlight distinctive characteristics of such textbooks. The present paper introduces one such analysis tool and describes some of the results from its application to three textbook series from distinct periods in Japanese EFL history. In so doing, we aim to encourage the use of textual analysis and seek to expose salient features of EFL texts which would likely remain hidden without such analytical techniques

Second language user support

Computer users rarely experience entirely trouble-free interaction. The natural variety ofindividuals ensures that no software systems yield constantly fluent interaction for allusers. In consequence, software designers often strive to ameliorate this situation bybuilding 'user support' into their systems. User support can take different forms but,conventionally, each aims to assist the needy end-user by means of facilities directly supporting the performance of certain operations, or through supply of information thatadvises the user on available system functionality.The present paper briefly characterises a range of user support facilities before describingone requirement in greater detail. This aspect considers the needs of users whose mother-tongue is not English, but who are obliged to use English-based information systems. Inthis context, 'helping the user' must reasonably extend beyond mere advice on systemoperation to selective elucidation of information content. We regard this move as alogical extension of the user support concept, by seeking to address specific interactionneeds in a target user population. An example of this approach is described through aninformation system, in the domain of civil engineering, for native Chinese speakers ofEnglish

A trial was planted at Merredin in 1976 on Salmon Gum soil with the aim of testing the drought tolerance of Gamenya, Madden and Insignia wheat

Summary of experimental results - Wheat protein survey

Wheat protein survey Seeding rate x grain protein - 72NA33. Seeding rate x grain protein - 72M28. Temperature effects on flower set of lupin - 72GL4. Wheat protein survey - A survey of 130 farmers in 13 Shires of the high protein area around Merredin was undertaken in the few weeks prior to the 1972 harvest. Grain samples were forwarded by farmers after supplying site data including yield estimate. A soil sample was collected on which % soil N was determined. This information together with grain protein percentage was included in multiple regression, and stepwise regression analyses
