Antibiotics are mandatory additives in semen extenders to control bacterial contamination. The worldwide increase in resistance to conventional antibiotics requires the search for alternatives not only for animal artificial insemination industries, but also for veterinary and human medicine. Cationic antimicrobial peptides are of interest as a novel class of antimicrobial additives for boar sem...

Piglets (n = 128) weaned at 21 days of age were used in a 35-day seeder model to evaluate the effects of dietary additives differing in active ingredients, chemical, and physical formulation, and dose on Salmonella colonization and shedding and intestinal microbial populations. Treatments were a negative control (basal diet), the positive control (challenged, basal diet), and six treatments si...

Douglas J. Beecher reported on the methodology that a U.S. Federal Bureau of Investigation laboratory used to identify an intentionally anthrax-contaminated letter(s) among mail collected from a Congressional building or postal facility that serves the U.S. Congress after the incident of contamination that occurred on 15 October 2001 (1). The described sampling strategy and initial screening an...

Food additives have been in use since prehistoric times. Early additives included salt, honey, wine and spices, all used largely for preservative or flavouring purposes. Later methods of preserving food included salting and smoke-curing of meats to enable an all round year's supply. In recent times there has been a considerable increase in the number and nature of additives available; they are ...

A series of laboratory tests were conducted to assess the effects of Fe-containing fuel additives on aerosols emitted by a diesel engine retrofitted with a sintered metal filter (SMF) system. Emission measurements performed upstream and downstream of the SMF system were compared, for cases when the engine was fueled with neat ultralow sulfur diesel (ULSD) and with ULSD treated with two formulat...

Although core, animal-reminder, and contamination disgust are viewed as distinct "types" of disgust vulnerabilities, the extent to which individual differences in the three disgust domains uniquely predict contamination-related anxiety and avoidance remains unclear. Three studies were conducted to fill this important gap in the literature. Study 1 was conducted to first determine if the three t...

the present study was carried out to evaluate the effects of vegetable fat sources and additives on performance and morphological parameters of the small intestine of arain broiler chickens. birds were randomly used in a 2×3 factorial arrangement of dietary treatments included two fat sources (canola or pumpkin seed) and three additives (without additive, 0.1 g/kg probiotic and 0.15 g/kg virgin...

Article history: Received 15 April 2016 Received in revised form 27 September 2016 Accepted 5 October 2016 Available online 6 October 2016 In this study, Re-Ni alloys with high Re content were electrodeposited on copper substrates from aqueous solutions containing additives with a combination of vanillin, sodium lauryl sulfate and gelatin. The bath additives were found to have a significant eff...
