Cost of Production Forecast – U.S. vs. Canada Comparison

Posted in: Production by admin on January 1, 2009 | No Comments

In hog production Canada has an advantage in sow production because of productivity and health, the US has an advantage in grow-finish because of facility costs, asset utilization and bigger pigs. Canada has an advantage in grow-finish because of feed and health. Genetics is neutral. In Processing Canada has an advantage because of the immigration policy but the US has a large Hispanic work force. In regards to asset utlization and economies of scale the US has the advantage because of more double shifts and bigger plants. However, Canada has an advantage of being able to focus more on the customer because of smaller plants that are able to provide a customized product. With regards to marketing the US has a larger domestic market but Canada has a strong international recognition. However, the US has an advantage with regards to transportation because of box cars and being a larger world consumer.

Leadership for Positive Change

Posted in: Production by admin on | No Comments

In 2005, the Canadian Pork Council launched the Animal Care Assessment,
or ACA, an auditable on-farm program for animal care. The program follows
in the footsteps of the on-farm food safety program, CQA®, which is now a
core program in the Canadian hog industry.
Producers, already burdened with an increasing array of programs and
requirements, voluntary and mandatory initiatives, may wonder why such a
program is needed, and what value it will bring. This paper outlines
the pressures that led to the creation of the program, the steps and challenges
faced in developing the initiative, and the current environment that makes
having such a program critical. It was concluded that developing a national, credible, animal care program was necessary given both the domestic and international pressures facing the industry. But building the program is not enough. Producers need to participate, and to participate, they need to see a benefit. While the incentives are not financial, they are still clear. Without such a program, without such a defense, to domestic and international customers and the public, there is little to stand on.

In vitro digestibility techniques to predict digestible energy content of common ingredients and feed samples in grower pigs

Posted in: Production by admin on | No Comments

The regression equation developed in the present study can be
used to estimate the variation in DE content across ingredients and mixed
diets in swine. The in vitro technique can also be useful to calibrate near infrared
reflectance spectroscopy so that DE content can be predicted rapidly in
field situations.

Longitudinal Study of Salmonella Dispersion and the Role of Environmental Contamination in Commercial Swine Production Systems

Posted in: Production by admin on | No Comments

This study investigated the roles of various environmental sources, such as truck-washing systems, waste processing
lagoons, and other sources, as potential contributors to the exposure and dissemination of Salmonella in commercial swine production systems. Four cohorts of nursery age swine herds which originated from distinct farm flows were selected. In addition, cross-sectional sampling of four truck wash stations selected based on the types of disinfectants and sources of water used for sanitizing trucks were tested. Salmonella isolates were recovered from pigs (feces, cecal contents, and mesenteric lymph nodes) and environmental sources (barn floor, lagoon, barn flush, trucks, and holding pens). Antimicrobial susceptibility testing and genotyping were conducted using Kirby-Bauer disk diffusion and amplified fragment length polymorphism, respectively. Salmonella prevalence significantly increased with age from late nursery to slaughter for all of the cohorts (P  0.007). In two of three instances, all three pig holding pens (lairage) sampled at processing were Salmonella positive. The predominant antibiotypes for all sources included ACSSuT (51.8%), SSuT (16.8%), T (6%), and pansusceptible (7.4%). For the isolates obtained at the farms, the ACSSuT phenotype was 5.6 times more likely to be found in the animals than in the environment (95% confidence interval, 4.4 to 7.2 times).
Serogroup B was the most common serogroup (79%), followed by serogroup E (10.4%). Despite the fact that the four production flows were independent, 1 of the 11 genotypic clusters (cluster A1) was commonly detected in any type of sample regardless of its origin. Five of the genotypic clusters (clusters A3, A4, A5, A6, and A7) contained isolates that originated from trucks and lairage swabs and also from cecal contents and/or mesenteric lymph nodes. More interestingly, genotypic clusters A3, A4, and A6 (but not clusters A5 and A7) were not detected on the farms. They originated from the trucks and lairage swabs and then were identified from the cecal contents and/or mesenteric lymph nodes. These findings underscore the significance of various environmental factors, including inadequate truck-washing systems, and emphasize the role of lairage contamination by Salmonella that has food safety significance.

Effect of xylanase supplementation of diets containing wheat distiller’s dried grains with solubles on energy, amino acid and phosphorus digestibility and growth performance of grower-finisher pigs

Posted in: Production by admin on | No Comments

The differential response of supplementary xylanase to wheat versus wheat DDGS diets indicates that the specific xylanase activity used in the present study matches the arabinoxylans in wheat, but not in the wheat DDGS. As a note of caution, the digestible lysine content of wheat DDGS from an oldstyle ethanol plant that was studied in the present study may not reflect wheat DDGS produced in new generation ethanol plants. Further studies are required to
assess the impact of improved DDGS production methods on nutrient digestibility of wheat DDGS in swine, to improve nutrient digestibility in pigs fed diets containing wheat DDGS, or to identify factors associated with reduced nutrient digestibility of wheat DDGS.

Canada Regroups After COOL

Posted in: Production by admin on | No Comments

The Canadian hog industry has faced many challenges in recent years. The trends that continue to unfold will surely affect the supply of pigs, market hogs and pork that cross the U.S. border over the next year or so. As we take a closer look at pricing, margins and developments in the Canadian market, unfortunately, one of the biggest developments that must be addressed is mandatory country-of-origin labeling (COOL). Looking ahead, it can be expected
that Canadian hog inventories will continue to decline through 2009, although at a slower pace. Based on grain and hog price forecasts, Canadian hog producers might be in the black this spring and summer, but not by much. Margins will dip back into the red in the fall.

Written Euthanasia Protocols Required

Posted in: Production by admin on | No Comments

 Jim Moody, vice president of marketing and finishing at The Hanor Company, Spring Green, WI, and Michelle Jens, DVM and director of sow health at Audubon- Manning Veterinary Clinic (AMVC) Management Services, Audubon, LA, addressed the Swine Housing and Transport Forum held on June 2, in Des Moines. They stated that straightforward guidelines for euthanasia must be drafted into a farm protocol, including the training necessary to ensure it is accomplished effectively. Some key considerations in writing a euthanasia protocol, including the method of choice, are:

• Risk to human safety — The chosen method should not put producers/ employees at risk. “Safety is very important,” Moody emphasizes. “Over the years, I have seen people who have accidentally shot themselves while using a bolt gun and I’ve seen people who have accidentally electrocuted themselves. Training is very important.”
• Skill required — A critical part of the training is learning the landmarks for the most effective application of the captive bolt or other methods. Jens reminds that these landmarks are different based on the size and shape of the animal (See Figure 1). Especially for mature sows and boars, the shape of the head and face (dish, flat, bulge) affects the thickness of the skull bones and the size of the sinus cavity, which must be penetrated to reach the brain.
• Aesthetics for the observer and the operator — “There is nothing about euthanizing an animal that is pleasant, but there are some techniques that are better than others,” Moody continues. “Work with your people to make sure they are comfortable with what they are doing. If they are not, find someone else or find an acceptable alternative for euthanizing a pig.”
• Understand the limitations of the method — “Some techniques require a two-step process. I try to stay away from those,” Moody says. With those methods, the animal is rendered unconscious, requiring a second step to complete the euthanasia process. C. Scanlon Daniels, DVM with Circle H Headquarters, LLC, Dalhart, TX, adds: “Some people commonly refer to captive bolt guns as ‘stun guns’ The thing about stunning an animal is the stunning is what causes the insensibility or loss of consciousness. Stunning may or may not be permanent, so when we talk about some captive bolt guns, the length of the bolt and how well that captive bolt gun is maintained is important. “Some captive bolt guns may only cause stunning, where if the animal is left, it may regain consciousness. The other point, of course, is that stunning or temporary insensibility must be followed up with a secondary step, such as bleeding out or pithing in order to cause death.”                                                                                                                                                                                                                                       • Cost — From a practical standpoint, the cost of various options must be considered. Moody notes. The final and critical step in the euthanasia process is determining if the process was successful — confirmation of death. “We need to make sure we and our employees are trained to distinguish whether a pig is dead or alive,” Moody states.

Effects of management, environmental and temporal factors on mortality and feed consumption in integrated swine fattening farms

Posted in: Environment by admin on | No Comments

The aim this study is to assess the effects of environmental, management, housing and temporal factors on two production parameters that impact the costs in all-in all-out swine fattening systems: mortality and feed consumed per marketed hog. The study also aims to estimate the contribution of the finishing herd and batch to the total variability of mortality and feed consumed per marketed hog. The study, conducted under ‘real field’ conditions, confirmed the negative effect of non-pelleted feed on average feed intake per marketed hog. The considerable effect of particular origin farms on mortality risk suggest including this data on further research. A high level of care provided by the farmers to the pigs contributed to reduce the risk of mortality. Both mortality and feed performance were influenced by the season and the year but the effect of the year on feed intake was modified by the average final weight of the batch and its level of mortality. Our results suggest that a constant effect of ‘the farm itself’ on mortality would be small or non-existent. On the other hand, by investigating and improving permanent farm characteristics a substantial profit is expected in the long run as a result of lower feed costs. However management factors at the individual batch level had the greatest impact on mortality and feed intake in all-in-all-out fattening farms. Also, uncertainty about mortality and feed intake tended to be higher in cold template periods than in other months.

Validation of the QTL on SSC4 for meat and carcass quality traits in a commercial crossbred pig population

Posted in: Meat Quality by admin on | No Comments

The objective of this study was to validate several QTL on porcine chromosome 4 responsible for meat and carcass quality traits. Regression analysis resulted in the validation of three QTL within the interval: Minolta a* loin, back fat thickness and the weight of trimmed ham. The results were additionally confirmed by factor analysis. Candidate genes were proposed for meat colour, which was the most evident QTL validated in this study.

Response to dietary digestible energy concentration in growing pigs fed cereal grain-based diets

Posted in: Energy by admin on | No Comments

The objective of these experiments was to determine how changes in dietary DE concentration, achieved through graded changes in diet composition, would affect the performance and carcass composition of growing pigs. It was found that the value per pig was unaffected by increasing dietary energy content and returns above feed costs were reduced. Increasing the energy density of the diet for growing pigs through incremental changes in dietary composition had a variable impact on overall growth performance and carcass quality. Also increasing the dietary DE was found to have no effect on variations in BW at the time of marketing.
