Tail biting has several identified feeding-related risk factors. Tail biters are often said to be lighter and thinner than other pigs in the pen, possibly because of nutrition-related problems such as reduced feed intake or inability to use nutrients efficiently. This can lead to an increase in foraging behavior and tail biting. In this study, a total of 55 pigs of different ages were selected ...

One hundred and twenty pigs were used to evaluate the effects of housing indoors on concrete slats or outside in dirt lots on tail biting, weight gains, behavior and immune function for pigs with intact tails or with tails docked. Pig performance was largely not influenced by treatments, even when cannibalism was found. When pigs began biting tails in particular pens, many pigs’ tails were not ...

AIM Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit. CASE DESCRIPTION A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an un...

Basic properties of a characteristic matrix for a tail-biting convolutional code are investigated. A tail-biting convolutional code can be regarded as a linear block code. Since the corresponding scalar generator matrix G has a kind of cyclic structure, an associated characteristic matrix also has a cyclic structure, from which basic properties of a characteristic matrix are obtained. Next, usi...

Compounds thought to be effective against mosquitoes as either 'insecticides' or 'repellents' have recently been shown to contain properties of both, or possess other behavior-modifying actions. Prompted in part by these reports, we conducted posterior analyses of our data to examine some interrelated statistical issues inherent in our bioassay system. Using a modified K&D module, the responses...

objective: this is a parallel, three group, randomized, controlled clinical trial, with outcomes evaluated up to three months after randomization for children and adolescents with chronic nail biting. the current study investigates the efficacy of habit reversal training (hrt) and compares its effect with object manipulation training (omt) considering the limitations of the current literature ....

BACKGROUND Robust malaria vector surveillance is essential for optimally selecting and targeting vector control measures. Sixty-two vector surveillance sites were established between 2005 and 2008 by the national malaria surveillance program in China to measure Anopheles sinensis human biting rates. Using these data to determine the primary ecological drivers of malaria vector human biting rate...

BACKGROUND Tail biting is a common welfare problem in pig production and in addition to being a sign of underlying welfare problems, tail biting reduces welfare in itself. The aim of this study was to evaluate the effects of tail biting on different pre and post mortem indicators of stress in slaughter pigs and on carcass and meat characteristics. A total of 12 tail bitten (TB) and 13 control (...

PURPOSE We describe a patient presenting with a vascular mass of the lower lip with a history of traumatic lip-biting. The lesion was treated with preoperative intravascular embolic therapy and surgical excision. SUMMARY Arteriovenous fistula (AVF) of the head and neck are vascular lesions with a single connection between the involved artery and vein. Trauma to the area, often in the distant ...
