2021年初,阿根廷的官方统计数据显示,2020年蓝莓产量为1.8万t,其中近1.1万t新鲜蓝莓用于出口。刚刚结束的收获季和出口季显示,2021年阿根廷蓝莓产量及出口量均下降。初步统计显示,2021年阿根廷蓝莓出口量为8000 t,蓝莓种植面积缩小。究其原因,主要有运营和税收成本高、美元化、高通货膨胀以及缺乏政府部门对蓝莓行业的指导政策等,这些原因与阿根廷的柑桔产业类似。所不同的是,阿根廷柑桔主要销往国内市场,但阿根廷的蓝莓主要销往国际市场。 相似文献

Have you made the decision to sell your veterinary practice and enter a new stage of lifé If so, the next big question is how do you maximise the sale price and minimise your capital gains tax. of such points and potentially bring them up to the standard of the rest of your business. For example is your store or practice in need of a refit? Do you need to update equipment, train staff or review stock choices? 相似文献

In summary, therefore, my experiences as a witness have been divided into three major areas. In the first, in what was essentially the political process, the game was charge and counter-charge, and the rules, such as they were, were fairly loose. In the second area, that of administrative hearings, the rulesare somewhat tighter, but still not as restrictive as those of a full court session. In court session you are always sworn, carefully qualified as an expert and almost invariably subjected to searching cross- examination. The rules of evidence are strictly adhered to. This is the situation where your freedom of action is most restricted, and is the most rigorous of the situations in which you will use your expertise. However, in the last analysis, you should remember that all that is required of you are simple statements of fact,and your best opinions. Make your statements simple, consistent, and concise, and keep your answers on cross-examination as short as possible.Expert appearances under any of these conditions are very stressful circumstances. They will absorb your attention entirely for some time before you make your appearance. You will feel totally drained after them,and images from the hearing will reverberate in your mind for days. They are, nevertheless, ultimately satisfying experiences. This is because the only measure of the quality of your research is how much it changes the way things are done. Appearances as an expert are a sure sign that you are contributing to change, and speak the significance of your expertise. 相似文献

Extract The first and over-riding consideration in the basic management of a successful practice is to get your attitude right and the attitude of all your associates (veterinary and lay) oriented aright. Earnest solicitude, genuine concern and enthusiastic interest are the attitudes to shape the careers of veterinary success. Don't sell yourself short. 相似文献

In order to run a small business effectively you must be in financial control and this means that you have to be aware how the business is performing. If you wait until your accountant has got out the annual accounts valuable time has been wasted in making necessary decisions and corrections to poor trends in your business so monthly/quarterly records are required. Decisions as to whether you can afford to take another assistant, set up a branch surgery, the level of your fee increases, whether to buy or lease your cars; are all dependent on having available up to date financial knowledge of your business. If you have a microcomputer in the practice you can use spreadsheets which will allow the accurate prediction of cash flow or profitability. You can also ask the question 'what happens if...?' and get the answer in seconds. But even without a computer, financial control can be easily maintained if you are prepared to spend a couple of hours each month with your practice figures. 相似文献

The aim of this evaluation study was to assess the possible role of a specific nutraceutical diet in relieving main clinical symptoms of chronic bilateral otitis externa (occlusion of ear canal, erythema, discharge quantity, and odor) in 30 adult dogs. Thirty dogs of different breeds (mean age?±?SEM; 6.03?±?0.15 years and mean weight?±?SEM; 32.01?±?1.17 Kg; 53.3 % males, 46.6 % females) with evident chronic clinical otitis symptoms were equally divided and randomly assigned to receive either the nutraceutical diet (ND group) or a standard diet (SD group) over a period of 90 days. In all cases a topical pharmacological treatment was given. The nutraceutical diet, also endowed with anti-inflammatory and antioxidant activities, significantly decreased the mean score intensity of all symptoms after 90 days of intervention (P?<?0.0001) with the exception of Malassezia pachydermatis infection which was only slightly reduced. Our investigation is one of the few evidence-based results where a commercial nutraceutical diet has been proven effective, in combination with drugs, in relieving otitis externa-related symptoms. This study opens new insights into otitis externa clinical management providing evidence of efficacy of a combined therapy with drugs and a specific nutraceutical diet. 相似文献

The presence and importance of visual oestrous symptoms and the relation to conception, breed, housing system and milk yield were studied. Data were collected from a Swedish research herd during a 16-year period. Local, secondary and primary oestrous symptoms and an overall oestrus intensity score (OI) were studied. Decreasing trends in oestrous expression and conception rates (CR), and an increase in CR with more intensive oestrus, from 24% at OI score one (very week) to 54% at OI score five (very strong) were observed. The mean interval from first to last observed oestrus symptom was long with a large variation (54?±?SD?=?32?h). Generally, irrespectively of housing system, Swedish Red cows had higher CR, more intensive oestruses and longer oestrus durations compared to Swedish Holstein cows. Local oestrous symptoms, with CR of 24–28%, were most frequently detected, which is why more attention should be paid to local oestrous symptoms. 相似文献

The present study was undertaken to estimate effect of various genetic and non-genetic factors on persistency of milk production and to identify the most appropriate persistency method that fits best in our environment. In the present study, effects of different non-genetic factors, viz. year, season, days to attain peak yield, and genetic group based on the level of exotic inheritance on persistency of milk yield in crossbred cattle were studied. Data comprised of 686 first lactation daily milk yield records of crossbred cattle that were maintained at GADVASU dairy farm over a period of 25 years from 1991 to 2015 were utilized to calculate persistency coefficients by four methods, viz., Ludwick and Peterson method (P1), Mahadevan method (P2), ratio method (P3), and Prasad et al. method (P4). Overall least squares means for persistency by Ludwick and Peterson method (P1), Mahadevan method (P2), ratio method (P3), and Prasad et al. method (P4) were 0.896?±?0.096, 1.385?±?0.224, 187.207?±?26.398, and 0.621?±?0.098, respectively. Effect of sires was significant (P?<?0.05) on P2 and P4 methods. Effect of genetic group on all four methods was non-significant. Period of calving had significant (P?<?0.01) effect on persistency of milk yield (P2, P3, and P4 methods). Effect of season of calving on persistency of milk yield was found to be significant in all estimates obtained by the four methods. Summer and autumn calvers were most persistent whereas spring and winter calvers were least persistent for (P2, P3, and P4 methods). Persistency of milk yield was significantly (P?<?0.05) affected by days to attain peak yield in P1 and P2 methods. Maximum persistency was obtained in animals attaining peak at 41–57 days of lactation and minimum in <?41 days for Mahadevan method and ratio method. The highest heritability of persistency and minimum value of standard error was estimated as 0.275?±?0.11 for the Mahadevan method followed by the Prasad method (0.197?±?0.10) by half sib correlation method. The maximum coefficient of variation which indicates available variability was estimated as 20.788% for persistency by the Mahadevan method followed by 18.969% for the Prasad method. The highest correlation was also observed between P1 and P3 methods by Spearman’s and Pearson’s correlation for least squares breeding value of the sires. On the basis of heritability, standard error of heritability, and coefficient of variation, it can be concluded that the Mahadevan method followed by the Prasad method suits best to our environment for animals in first lactation as well as they can be utilized for effective selection for higher persistency in crossbred animals of Punjab. 相似文献

1. Behavioural and neural responses of 65 broilers to head-to-cloaca electrical stunning were evaluated and meat quality was assessed on two groups of 25 broilers stunned either head to cloaca, or in a conventional water bath method. 2. On the EEG recordings, a general epileptiform insult was observed when applying a current of 100?mA (100?Hz) or 70?mA (70?Hz) for 1·5?s. This general epileptiform insult shows a tonic, clonic and exhaustion phase followed by spikes of alpha, beta, theta and delta waves with duration of on average 34?±?12?s and 39?±?23?s respectively. These birds may have been unconscious for 20?s or longer, according to the correlation dimension analyses. 3. The heart rate decreased significantly (P? 4. Within a confidence limit of 95%, taking into account the number of animals with a reliable EEG, the chance of an effective stun of all broilers lies between 0·9 and 1·0?with a current of 70?mA (100?Hz for 1·5?s; n?=?28) and with 100?mA (100?Hz for 1·5?s; n?=?27). 5. The shear force of breast fillets was slightly lower (P? 6. It can be concluded that broilers are effectively stunned with the head-cloaca method by using a controlled current of 70?mA or 100?mA for 1·5?s. The fillets and legs of bird stunned head-cloaca showed fewer blood splashes in the muscles compared with birds stunned in a conventional water bath. 相似文献
