Canadian National Dairy Study: Describing Canadian dairy producer practices and perceptions surrounding cull cow management
No full textFarmer decisions surrounding culling have an important effect on the health and welfare of cull cows. The objectives of this study were to describe the self-reported shipment behaviors of Canadian dairy producers and understand farmer perspectives on the factors that were most influential in their decision to cull a cow. A nationwide survey was administered between March and April 2015 that included 192 questions covering producer background information, farm characteristics, biosecurity practices, disease prevalence, calf health, cow welfare, lameness, milking hygiene, reproduction, and Internet and social media use. The survey yielded a 12% response rate; a total of 1,076 respondents (78% of all survey respondents completed the culling section of the survey) were included in this study for analysis. Approximately 80, 51, and 38% of respondents reported shipping at least 1 cow to auction, direct to slaughter, and to another dairy farm in the past 12 mo, respectively. Ability of the cow to remain standing (93% of respondents) and drug withdrawal times (92% of respondents) were identified as the most important factors for consideration when culling cows. The time between culling decision and when the cow was actually transported was longer for lame cows than sick cows; almost 70% of respondents reported that cows culled for illness were typically shipped within 1 wk of culling decision, whereas only 51% of respondents indicated the same was true for lame cows. Last, Canadian dairy producers generally exhibited strong confidence that their culled cows would arrive at slaughter in the same condition as they left, but felt very unsure about knowing the location of their final destination. These results highlight several gaps between producer perceptions and the true situation, and can be used to develop tailored programs and inform policy and regulatory decisions aimed at improving cull cow decisions and cow welfare.Dairy Farmers of CanadaAgriculture and Agri-Food Canad
Bank privatization in Argentina : a model of political constraints and differential outcomes
No full textBased on results from country case studies, many researchers have claimed that political constraints affect bank privatization transactions, which in turn affect the post-privatization performance of the banking sector. But no study has either econometrically tested how political constraints affect bank privatization transactions or theretically modeled the privatization transaction. The authors present a simple theoretical framework that models the inherent tradeoffs faced by governments and potential buyers in privatization transactions involving banks. The potential buyer is concerned about the probability that the bank will remain solvent, about the profits it will earn after privatization, and about the price paid for the assets and liabilities. The government is concerned about the price received for the assets, about layoffs, and about service coverage after privatization. The evidence from bank privatization transactions in Argentina in the 1990s supports several of their theoretical predictions. In particular, provinces with highfiscal deficits were willing to accept layoffs and to guarantee a larger part of the privatized banks'portfolio in return for a higher price. The tequila crisis (Mexico's economic crisis in 1994-95) meant that politicians could protect fewer jobs and had to assume a greater share of their public banks'assets. Evidence of better performance at banks privatized after Mexico's crisis suggests that, by tying politicians'hands, the crisis may have brought unforeseen benefits. This conjecture awaits further empirical validation, but the authors hope that by explicitly incorporating the incentives politicians face, analysis can begin to address the question of why some privatizations succeed more than others.Economic Theory&Research,International Terrorism&Counterterrorism,Banks&Banking Reform,Municipal Financial Management,Financial Crisis Management&Restructuring,Banks&Banking Reform,Municipal Financial Management,Economic Theory&Research,Financial Crisis Management&Restructuring,International Terrorism&Counterterrorism

The influence of Megasphaera elsdenii on rumen morphometrics of cull cows immediately stepped up to a high-energy finishing diet
No full text© The Author(s) 2019. Published by Oxford University Press on behalf of the American Society of Animal Science. cc-by-ncForty-five beef cull cows [body weight (BW) = 503 ± 58 kg; body condition score (BCS) = 2.1 ± 0.6] were randomized into two treatments to compare the effects of oral drenching of no probiotic vs. 100 mL of Megasphaera elsdenii NCIMB 41125 (M. elsdenii culture; Lactipro Advance; 2 × 108 cfu/mL; MS Biotec, Inc., Wamego, KS) on the realimentation of cull cows. The study featured a rapid 0-d step-up of concentrate-naïve cull cows to a 90% concentrate diet (1.43 Mcal/kg of NEg). The cows were finished for 35 d and were fitted with a wireless rumination tag (Allflex Flex Tag; SCR Engineers, Ltd, Netanya, Israel), which tracked head movement to record eating and chewing activity. Rumen morphometrics was recorded on the harvest floor, with each carcass assigned a rumenitis score, and a fragment of the cranial sac removed for further papillae analysis. An additional 23, thin, non-fed cull cows were harvested at the same abattoir to compare the effects of concentrate realimentation on ruminal morphometrics. Megasphaera elsdenii culture-drenched cattle registered a 13.3% increase in rumination time (39.27 min/d, P = 0.03) during the first week of the trial compared to controls. A numerical rumination advantage for M. elsdenii culture-administered cattle was observed during week 2 of trial (P = 0.17), with no differences between treatments from weeks 3 to 5 (P ≥ 0.40). Subjective rumenitis evaluations approached a tendency (P = 0.12), with non-M. elsdenii culture-drenched concentrate-fed cattle logging twice the score of their day 0 cohorts (2.52 vs. 1.17) suggesting considerable lactic insults occurred to the ruminal epithelium in the short 35-d trial. Despite the short feeding duration, concentrate realimentation prompted a significant improvement in mean papillae area (P < 0.01). Among concentrate-fed treatments, M. elsdenii culture-drenched cattle posted superior absorptive surface area (P = 0.01) and a greater ratio of papillae area of absorptive surface area (P = 0.05), suggesting that M. elsdenii culture is favorably altering the ecology of the rumen and promoting papillae growth perhaps by mitigating lactate-driven pH drops. In conclusion, M. elsdenii culture application in a 0-d step-up protocol to finishing diets can help mitigate the effects of ruminal acidosis

Representations of swine flu: Perspectives from a Malaysian pig farm
No full text© The Author(s), 2010. This is the author's accepted manuscript. The final published article is available from the link below.Novel influenza viruses are seen, internationally, as posing considerable health challenges, but public responses to such viruses are often rooted in cultural representations of disease and risk. However, little research has been conducted in locations associated with the origin of a pandemic. We examined representations and risk perceptions associated with swine flu amongst 120 Malaysian pig farmers. Thirty-seven per cent of respondents felt at particular risk of infection, two-thirds were somewhat or very concerned about being infected. Those respondents who were the most anxious believed particular societal “out-groups” (homosexuals, the homeless and prostitutes) to be at higher infection risk. Although few (4%) reported direct discrimination, 46% claimed friends had avoided them since the swine flu outbreak. Findings are discussed in the context of evolutionary, social representations and terror management theories of response to pandemic threat
An Economic Assessment of the BSE Crisis in Canada: Impact of Border Closure and BSE Recovery Programs
No full textThis article assesses the economic consequences of three alternative government responses to the BSE crisis in Canada: 1) expansion in slaughter capacity; 2) partial destruction of the cattle herd; and 3) deficiency payments. Each of these policies is evaluated under four different border situations: 1) autarky; 2) free trade in young beef only; 3) free trade in young beef and cattle; and 4) complete free trade. The results of the policy analysis are quite sensitive to the border assumptions, making it impossible to select a “best†policy without perfect foresight with respect to the timing and the extent of the border opening.BSE, cattle and beef, partial equilibrium model, simulation, trade ban, International Relations/Trade, Livestock Production/Industries,
