Article history: Received 7 November 2012 Available online 4 February 2013 We examined how affective (AC), normative (NC), perceived sacrifice (PS), and few alternatives (FA) commitments combine to form profiles and determine turnover intention and turnover.We theorized that three mechanisms account for how profiles operate, i.e., the degree to which membership is internally regulated, the perc...

Caprylic acid (CA) and Yucca schidigera (YS) extract have many functional and nutritional properties that may have applications in animal nutrition. These beneficial effects include improvement of growth performance, immunity and anti-microbial activity. This study was conducted to assess the effects of dietary supplementation with CA and YS extract on growth performance, relative organ weight,...

This paper develops a new and natural parallel vector model, and shows that for all k ≥ 1, the languages recognizable in O(log n) time and polynomial work in the model are exactly those in NC. Some improvements to other simulations in parallel models and reversal complexity are given.

The residual activities of transgenic corn-derived and 2 commercial microbial phytases (PA and PB) along the gastrointestinal tract (GIT) of laying hens were compared to evaluate their relative resistance to hydrolysis in the GIT when added to P-deficient diets. The treatments consisted of a negative control (NC) diet containing 0.10 nonphytate P and an NC diet supplemented with transgenic corn...

A total of 420 day-old male Ross chicks were weighed at d 1 of life and assigned to test diets to assess the efficacy of a new Buttiauxella spp. phytase expressed in Trichoderma reesei. Diets were: positive control (PC) adequate in nutrients and negative control (NC) diet (40% and 17% less available phosphorous (P) and calcium (Ca), respectively) supplemented with 6 levels of phytase 0, 250, 50...

Improving the efficiency of P use by pigs is especially important for lactating sows, whose metabolic requirements for P and Ca are high. The effect of a sp. phytase on lactating sow performance and nutrient digestibility was investigated using the combined data set for 6 studies. Treatments included a nutritionally adequate positive control diet (PC), a negative control diet (NC; with an avera...

AIMS Pre-treatment with dietary ω3 polyunsaturated fatty acids (ω3-PUFA) has been reported to reduce the incidence of new-onset atrial fibrillation (AF) following cardiac surgery. In a canine cardiac surgery model, we evaluated the impact of dietary ω3-PUFA on atrial electrophysiological properties, inflammatory markers, the atrial endothelin-1 (ET-1) system, and the expression and distribution...

Abstract Essential oils are potential antimicrobial alternatives and their applications in animal feeds limited due to fast absorption the upper gastrointestinal tract. This study investigated effects of encapsulated cinnamaldehyde (CIN) at 50 mg/kg or 100 on growth performance, organ weights, meat quality, intestinal morphology, jejunal gene expression, nutrient digestibility, ileal cecal micr...

OBJECTIVE The present study was conducted to investigate the effects of a lipid-coated zinc oxide (ZnO) supplement Shield Zn (SZ) at the sub-pharmacological concentration on intestinal morphology and gene expression in weanling pigs, with an aim to gain insights into the mechanism of actions for SZ. METHODS Forty 22-day-old weanling pigs were fed a nursery diet supplemented with 100 or 2,500 ...
