Abstract:

This Research Communication describes an investigation of the nutritional depletion of total mixed rations (TMR) by pest birds. We hypothesized that species-specific bird depredation of TMR can alter the nutritional composition of the ration and that these changes can negatively impact the performance of dairy cows. Blackbirds selected the high energy fraction of the TMR (i.e., flaked corn) and reduced starch, crude fat and total digestible nutrients during controlled feeding experiments. For Holsteins producing 37·1 kg of milk/d, dairy production modeling illustrated that total required net e

Abstract:

Inspired by bird feather structures that enable the resistance of powerful aerodynamic forces in addition to their lower weight to provide stable flight, a biomimetic composite turbine blade was proposed for a low-temperature organic Rankine cycle (ORC) turboexpander that is capable of producing lower weight expanders than that of stainless steel expanders, in addition to reduce its manufacturing cost, and hence it may contribute in spreading ORC across nonconventional power systems. For that purpose, the fluid–structure interaction (FSI) was numerically investigated for a composite turbine bl

Abstract:

Calcium (Ca) is an essential element for poultry and even a mild deficiency can lead to significant welfare and performance issues. As a result, it is often fed at levels in excess of requirement, partly as an insurance policy and, to some degree, because of its relatively low cost compared with other feed ingredients. However, when diets meet but do not exceed the phosphorus (P) requirements of the bird, a marginal Ca excess can interfere with P digestibility. This problem is exacerbated when phytases are used to provide some of the required P because Ca decreases the efficiency of phytate (I

Broiler chickens in the commercial setting are raised with antibiotics regularly, not only for disease prevention and treatment but also for body growth. The prevention and treatment of bacterial infections is critical to intensive poultry production. Antibiotics are natural, manufactured, or semi-synthetic compounds that inhibit or kill microorganisms. Primarily bacteria, they treat and prevent infections in humans and animals. Antibiotic use in poultry production has a cost; it contributes to an increase in drug-resistant infections in broiler chickens, which can be passed to humans and have

Cryopreservation is a fundamental technique for preserving the structural and functional integrity of biological material, particularly for the conservation of genetic resources in avian species.

Abstract:

ABSTRACT 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 rate of transmission within a flock were known, such an estimate could be determined from the change in the prevalence of colonized birds in a flock over time. The aim of this study was to dete

Abstract:

Audio data collected in commercial broiler houses are mixed sounds of different sources that contain useful information regarding bird health condition, bird behavior, and equipment operation. However, characterizations of the sounds of different sources in commercial broiler houses have not been well established. The objective of this study was, therefore, to determine the frequency ranges of six common sounds, including bird vocalization, fan, feed system, heater, wing flapping, and dustbathing, at bird ages of week 1 to 8 in a commercial Ross 708 broiler house. In addition, the frequencies

Abstract:A honeydew-producing scale insect, Stigmacoccus garmilleri (Margarodidae), is associated with oak trees (Quercus spp.) in highland forests of Mexico. Although feeding by ants on scale-insect honeydew is more frequently documented in the literature, the honeydew produced by feeding instars of S. garmilleri is sufficient to provide nourishment for birds. This study elucidates bird use of honeydew in the tropical montane forests near Chiconquiaco, Veracruz, Mexico, and uncovers patterns in honeydew foraging. Over a 2-mo period, 40 trees harbouring scale insects, located in both forest an

Purpose There is much anecdotal evidence that birds and their droppings are a major problem for the heritage profession. The purpose of this paper is to examine how serious heritage practitioners consider the bird impact to be. Design/methodology/approach An online survey was conducted of 59 Australian heritage professionals of between one and >20 year’s experience in the field. Findings Bird impacts were not considered of major concern to buildings. The longer experience a practitioner had, the less likely the impacts were considered an issue.

The computational bird model is presented with the Lagrange algorithm and Mooney–Rivlin hyperelastic material parameters which are validated against the experimental data found in the literature.

AbstractAustralian native, nonhuman animals at first intrigued and then disappointed newcomers as Australia was colonized by the British in the late eighteenth century. They were disparaged as unproductive and unpalatable oddities, killed as competitors to introduced species, or harvested as a source of fur and feathers for export. Focusing on the period 1803 to 1939, this paper examines one exception to this general pattern: the keeping of native animals as “pets.” Contemporary newspaper articles and advertisements are drawn upon to demonstrate that the Australian native fauna kept as pets we

Combining cinematic and diplomatic history, this article examines a curious relic of the détente phase of the Cold War, the fantasy-musical The Blue Bird. Released on the silver screen in 1976, The Blue Bird was the only U.S.-Soviet cinematic coproduction during the Cold War. The movie was made for a variety of commercial, artistic, and ideological reasons but failed to live up to expectations. The production was shambolic, critics were disdainful, and the film was a dud at the box office. The Blue Bird is largely forgotten nowadays, but the story of the film's production and reception sheds v

However, the price of edible bird nests decreased due to various shapes and sizes of EBN in the market. This study will design standard scaffolding nests followed by MS 2334:2011 and introduce t
