Simple Summary The severity of heat stress issues on dairy cows will increase as global warming progresses. Fortunately, major advances in environmental management, including fans, misters, sprinklers, and cooled waterbeds, can attenuate the effects of thermal stress on cow health, production, and reproduction. These cooling systems were, however,...
Article
Several technologies and techniques are available for mitigating greenhouse gas (GHG) emissions associated with dairy manure management in the barn, the storage unit, and the fields. For instance, incorporation of manure to soil, solid-liquid separation, composting, enclosed manure storage, and anaerobic digestion have been identified as good optio...
Article
Recent technological advances in the dairy industry have enabled Canadian farms with liquid manure systems to use mechanical solid-liquid separation paired with composting of the separated solids for on-farm production of low-cost bedding material. However, as several approaches are available, it is difficult for farmers to select the appropriate o...
Article
Canadian dairy producers have an increasing interest in recycled manure solids (RMS) as bedding material because of reduced availability of traditional bedding resources. Information regarding methods to obtain RMS and composition of RMS is very limited. Hence, a two-part investigation was developed to compare the performances of three mechanical s...
Article
Full-text available
During summer and winter months, pastures and outdoor pens represent the conventional means of providing exercise for dairy cows housed in tie-stall barns in the province of Québec, Canada. Unfortunately, outdoor pens require large spaces, and their leachates do not meet Québec’s environmental regulations. Therefore, there is a need to develop alte...
Article
Since 1990, worldwide egg production has increased on average 2.8% per year. This increase has drawn the attention of animal welfare advocates. In Canada, new challenges have emerged, among them: increased awareness in animal welfare and environmental footprint and a shift to cage-free egg production systems (CFSs). Welfare assessment of environmen...

Sometimes the contamination in pig facilities can persist even after the washing and disinfection procedure. Some factors could influence this persistence, such as bacteria type, biofilm formation, material type and washing parameters. Therefore, this review summarizes how the type of surface can influence bacteria colonization and how the washing...
Article
Full-text available
Animal welfare concerns have been a challenging issue for producers and international marketing. In laying hen production, cage-free systems (CFS) have been identified as an alternative to ensure the laying hens’ well-being. Nevertheless, in CFS, important environmental issues have been reported, decreasing indoor air quality. Environmental control...
Article
Recycled manure solids (RMS) produced in dairy farms from fresh manure need to be sanitized before using them as bedding material. However, the impact on air quality of composting RMS remains unknown. Four RMS composting methods were tested during a 10-day aging of piles in experimental chambers: static windrow (SW), turned windrow (TW), SW followi...

Article
Tie-stall housing (93%) and solid manure management (44%) are used on many dairy farms in the province of Quebec (Canada). This could however change in the near future since the rise in average herd size and the popularity of milking robots are such that the industry expects an increase in free-stall dairies managing manure with liquid systems. Thi...

Environment control in confined animal housing systems is typically based on heat and moisture production rates at predetermined ambient temperature levels measured between 1950 and 1980 (ASABE and ASHRAE Standards). This traditional method can fall short in meeting the true thermal needs of the animals as it does not account for factors, such as h...

During the winter months, cow-calves are generally confined in wintering sites consisting of a wintering pen (WP) which is combined with a vegetative filter strip (VFS). This approach is widely accepted and used as an economical and simple method for rearing cows during winter. Over the 15th last years, a series of research projects were conducted...

In developed countries, to support the demand, farmers have to produce a large quantity of high quality food. Primarily due to an improper storage, large quantities of agricultural products are downgraded and not commercialized. Indeed, in farms in the province of Quebec, 66,000 t year-1 of potatoes are wasted. Quebec policy regarding waste matter...
