The effect of two diets containing fish acid silage were studied, the first one offered as dry diet and the second one as a wet diet, in final culture cycle of PactS. Previous experiences showed that diets without fishmeal maintain same growth rate in semi intensive system, compared to diets containing 8% and 20% fish meal. Feeding trials were carried out in CENADAC （27°32′ S, 58030＇ W） in a semi intensive pond culture system for 122 days. Two experimental feed including fish silage, a liquid product obtained of fish residues treated by enzymes action, were formulated. Fish silage was prepared by mincing and blending fish viscera with sufficient formic acid （2.11% v/w） to attain a stable pH of 3.5. Fish were daily fed initially with the dry ration at 1.3% bw/d and at a rate of 0.55 g of protein/100 g of fish with the wet ration. At the end of the experience the average weight observed for dry fed fish was 1,513.5 g and 1,560.3 g for those wet fed. The daily growth was 3.69 g/d for the first group and 3.9 g/d for the second one. The final FCR was 2.72 and 3.01 for each group without significant differences. These results showed that it is possible to grow out paco with wet self made feed without fish meal and with similar growth that those fed dry diet.

Flower thrips are one of the key pests in production of southern highbush blueberries (vaccinium corymbosum L. × v. darrowi Camp). They feed on the reproductive parts of the flower and reduce yield. very few insecticides are available to manage thrips population. Therefore, it is necessary to evaluate pre-existing and experimental insecticides for their efficacy against thrips. There is also a high demand for reduced-risk insecticides that are less toxic to beneficial insects and the environment. In this study, a number of conventional and reduced-risk insecticides were evaluated against flower thrips on farms in Florida and Georgia and in the laboratory. The best performing insecticides were also evaluated in the laboratory for their effects on Orius insidiosus Say, which is a common thrips’ predator in Florida. Assail 70WP (Acetamiprid) and SpinTor 2SC (Spinosad) were the most promising insecticides in reducing thrips numbers in the field as well as in laboratory experiments. SpinTor 2SC killed all of the thrips in laboratory arenas within 4 hours of application and showed low toxicity toward O. insidiosus. All of the compounds tested performed as well as the conventional pesticide malathion.

Aim of the Study: The primary aim of the study was to test the effect of 2,4,5-trimethoxy-1-propenylbenzene (alpha asarone), a hypocholes terolaemic drug, on the progression of collagen induced arthritis (CIA) in mice. Olive oil,the vehicle of alpha-asarone, and dexamethasonewere used as control treatments. Set-Up: Four groups of DBA/1 mice were immunised with chicken type II collagen (CII) via the intradermal route and either left untreated or were treated with alpha asarone, olive oil, or dexamethasone. A non-immunised group was an additional control. Follow-Up: The thicknesses of the rear and front footpads were continuously monitored, and the levels of anti-collagen antibodies were measured at the end of the experiment. The animals were then sacrificed, and their rear and front limbs were removed and processed forhistological examination. Results: Alpha asarone had no anti-inflammatory effect on CIA, and in one third of the animals, it showed a proinflammatory effect that was characterised by a marked accumulation of neutrophils. Olive oil did not show any obvious antiinflammatory effect on CIA, but it lowered the level of CII antibodies by 50%, suggesting a potential long-term antiinflammatory effect. As expected, dexamethasone had a clear anti-inflammatory effect on CIA. Con- clusion: Alpha asarone did not show any antiinflammatory effect on CIA in the mice under the above conditions;however, the accumulation of neutrophils in the CIA lesions of mice treated with alpha asarone and the effect of olive oil in downregulating the levels of anti-CII antibodies in CIA are two findings that warrant further investigation.

Background: Separation-related disorders are prevalent in dogs and can result in problem behaviours such as inappropriate elimination, destructive behaviour, and distress vocalizations which occur when an owner is absent or perceived as absent. Numerous natural products are marketed for managing anxiety in dogs;however, few, if any, of these products have documented evidence of efficacy in veterinary behaviour. Purpose: This open, multicentric clinical trial aimed to assess the efficacy of a new supplement containing alpha-casozepine and fish muscle hydrolysate on the separation-related problem in dogs and the impact on the quality of life of dogs and their pet owners. Material and Methods: Fifty-one dogs with clinical signs compatible with separation-related problems were included. The dogs were treated with a complementary feed (Zylkene Plus, vetoquinol, France) for 30 days. Separation-related behaviour assessment (SRP), emotional disorders assessment (EDED) and the quality of life (QoL) of the pets and their pet owner were assessed at baseline and the end of the study by the veterinarians. In addition, owners were asked to rate their dog’s SRP weekly after enrolment using the same questionnaire that the veterinarian used at the beginning of the study. Results: There was a statistically significant improvement in the SRP, EDED, and QoL scores (P Conclusion: The results of this study support the hypothesis that the combination of alpha-casozepine and fish muscle hydrolysate is a promising and effective option to reduce the frequency and severity of separation-related behaviour in dogs and improve the quality of dogs and their owners.

oscar Juárez分享了用3ds Max和虚拟引擎创造迷人室内场景的过程人们常说“魔鬼藏于细节”,对室内场景而言确实如此。设计师必须集三维艺术家与室内设计师于一身,为了呈现照片般真实的效果,要动用一切所能。本教程分享了如何用虚拟引擎创建室内场景。我做的大多数室内效果图都会用到v-Ray,不过虚拟引擎已经越来越受欢迎了,它可以在整个场景内移动,有助于客户看项目。实际上,虚拟引擎对设计师也有帮助。
