Pigs from one farrowing group in which gilts were bred to farrow pigs that would be either 14 or 21 d of age at weaning, were divided into older and younger age groups (108 pigs per group) and penned 12 pigs per pen in a wean-to-finish facility. At the end of the nursery phase, half the pigs in each age group were removed, rerandomized, and commingled for the finishing phase. The other half rem...

The benefits of top down financial reporting regulation over the past eight decades are less obvious than its failures to achieve the purported goals. Perhaps it is time to give a chance to an alternative approach of regulatory competition.

Morphological quality of black walnut (Juglans nigra L.) seedlings largely dictates their capacity to establish well in plantations and their performance potential for use as rootstocks in grafting. Larger seedlings and rootstocks, attained from propagation at relatively low nursery sowing densities, have comparatively more expansive root systems for exploitation of soil resources and greater n...

Methods: A field trial was conducted on one group of nursery pigs (N=330). Pigs were randomly allocated to one of four groups that each received one of the following treatments at weaning: an experimental autogenous vaccine administered intramuscularly (IM) (n = 90); a standard autogenous vaccine administered IM (n = 90); a commercial bacterin, administered intraperitoneally (IP) (n = 60); or n...

Bronchial Asthma is defined by the history of respiratory symptoms such as wheeze, shortness breath, chest tightness and cough that vary over time in intensity, together with variable expiratory airflow limitation. Airflow limitation may later become persistent course disease. To compare findings eosinophil counts peripheral blood, induced sputum bronchoalveolar lavage fluid asthmatic patients ...

Cryptosporidiosis is a common gastrointestinal illness that is transmitted from infected persons, animals, or contaminated water or food. This article reports on an outbreak of cryptosporidiosis associated with an animal nursery at an agricultural show held in northern Tasmania during October 2001. Eighty-one per cent of cases (38/47) notified to the Tasmanian Department of Health and Human Ser...

We construct Edgeworth exchange economies equivalent to demand and supply environments typically used in bargaining models and market experiments. This formulation clearly delineates environment, institution, and behavior for these models and experiments. To illustrate, we examine results by Gode and Sunder, who simulate random behavior in a double auction and argue that this institution leads ...

Producing good quality seeds that perform well in the nursery continues to be challenging. High quality conifer seeds are obtained by optimizing collecting, processing, storing, and treating methodologies, and such quality is needed to consistently produce uniform nursery crops. Although new technologies are becoming available to evaluate seed quality, they have not been developed to the extent...

Four 28-d experiments involving 360 weanling pigs were conducted to investigate the effects of including spray-dried porcine plasma (SDPP) in diets from d 0 to 14 after weaning followed by feeding a common diet from d 14 to d 28. In Exp. 1, 80 weanling pigs (4.9 kg BW, 17 +/- 1 d of age) were used to determine the effects of substituting 0, 3, 6, 9, or 12% SDPP for dried skim milk (DSM) and L-l...
