Abstract Weaning stress and other environmental conditions can impact growing rabbit performance and carcass measurements. Therefore, investigating a feed ingredient that may mitigate these effects is important. The objective of this study was to determine if the addition of a phytogenic feed additive would improve performance and carcass measurements of growing rabbits. On October 22nd, 2018, a total of 16 (1.01 ± 0.02 kg BW) New Zealand White male rabbits were weaned and stratified by BW and allocated randomly to 1 of 2 groups representing 2 treatments: 1) Control (C; no phytogenic; n = 8) and 2) 454 g/ton phytogenic feed additive (PHYTO; n = 8). During the 42-d study, rabbits were housed in individual cages and offered a 18% CP and 2% fat commercial grower diet. All rabbits had ad libitum access to feed and water. Rabbits were weighed at the start of the study and weekly thereafter until the end of the feeding period when they were transported to a local abattoir, harvested, and carcass measurements recorded. Data were analyzed using PROC MIXED of SAS. Start weight, weekly BW, end BW, weekly gain, total gain, weekly intake, total intake, and G:F did not differ (P ≥ 0.11) between treatments. Carcass shrink percentage was greater (P = 0.003) from PHYTO compared with C. Whereas, HCW and dressing percentage were greater (P < 0.05) from C compared with PHYTO. Loin width did not differ (P = 0.89) between treatments. Ultimate pH was lower (P = 0.02) from PHYTO compared with C. Therefore, offering this specific phytogenic to weaned rabbits may not improve performance, but may impact certain carcass measurements. Further research is warranted to explore phytogenic impacts on carcass acceptability.

Mating Time

There are three key times during the year when deer management interacts with behavioural needs to influence pr oductivity. At calving time , average neonatal losses are 10-12%. The most common causes of perinatal mortality are dystocia, starvation and misadventure. Observational studies have shown that loss of contact between the hind and calf, calf beating by hinds and entanglement of calves in fences are consequences of calving environments with high stocking densities, that lack vegetative or topographical cover, allow disturbance by humans, or provide unfamiliar social or environmental conditions. Weaning is a second critical production phase when management affects pr oductivity. Early post-weaning growth rates in calves weaned before the rut are not influenced readily by feed quality. Reducing weaning stress using management tools such as confining the calves indoors for a few days, or adding some unrelated hinds to the weaned group can improve weight gains at this time. Another option is to delay weaning until the calves are older. Mating time is a third critical period dur ing which management needs to take behavioural needs into account. Appr opriate stag-hind ratios and management at mating that increase the chances of conception have been identified. Suitable social conditions at mating differ between yearling and adult hinds. Fence line pacing is frequently observed at the above three critical times and can occur at other times of the year in response to unfavourable conditions. Pacing consumes energy and contributes to erosion and fence maintenance requirements. Attention to the behavioural needs of deer can help improve performance through appropriate management systems.

And Performance

A recent series of experiments suggests that fostering superstitions can substantially improve performance on a variety of motor and cognitive tasks ( Damisch, Stoberock, & Mussweiler, 2010 ). We conducted two high-powered and precise replications of one of these experiments, examining if telling participants they had a lucky golf ball could improve their performance on a 10-shot golf task relative to controls. We found that the effect of superstition on performance is elusive: Participants told they had a lucky ball performed almost identically to controls. Our failure to replicate the target study was not due to lack of impact, lack of statistical power, differences in task difficulty, nor differences in participant belief in luck. A meta-analysis indicates significant heterogeneity in the effect of superstition on performance. This could be due to an unknown moderator, but no effect was observed among the studies with the strongest research designs (e.g., high power, a priori sampling plan).

AbstractA Bayesian decision support system was developed for the diagnosis of rheumatic disorders. Knowledge in this system is represented as evidential weights of findings. Simple weights were calculated as the logarithm of likelihood ratios on the basis of 1,000 consecutive patients from a rheumatological clinic. The effect of various methods to improve performance of the system by modification of the weights was studied. Three methods had a mathematical basis; a fourth consisted of weights adapted by a human expert, which allowed inclusion of diagnostic rules such as defined in widely accepted criteria sets. The system’s performance was measured in a test population of 570 different cases from the same clinic and compared with predictions of diagnostic outcome made by rheumatologists. The weights from a human expert gave optimal results (sensitivity 65% and specificity 96%), that were close to the physicians’ predictions (sensitivity 64% and specificity 98%). The methods to measure the performance of the various models used in this study emphasize sensitivity, specificity and the use of receiver operating characteristics.

Printing service order information systems sometimes experience problems in completing running business processes including, frequent loss and inaccuracy in registering orders from customers, often also losing order data from customers, recording orders often experience errors, resulting inaccurate reporting of order data. A computerized ordering service information system will greatly help improve performance and accuracy in making reports on business processes running at a company. The existence of enterprise modeling of information systems ordering printing services with the TOGAF framework will be a method that greatly helps management make a decision that will synergize with the business process activities at the company. So that the objectives of the system can be achieved properly. The TOGAF framework can be a solution and will help to produce a system architecture design, a business process architecture, a technology architecture, a number of proposed business opportunity strategy proposals and an ongoing system change proposal.
