“…Similarly, Safley and Westerman (1990) and Godbout et al ( 2010) noted lower CH 4 potential with a barley-based diet in their reviews of the literature. Although the rations fed at the study farm contained only 20% barley in the diet, barley is more common than corn in Manitoba and western Canada (Zhou et al, 2016). The second factor is that the IPCC 2019 default B 0 refers to fresh manure, whereas these samples were taken at the sump pit after some biodegradation had occurred.…”

Manure methane emissions over three years at a swine farm in western Canada

Swine manure is kept in outdoor storage facilities until it is applied to cropland.Anaerobic conditions facilitate microbial methane (CH 4 ) production at a rate that depends on temperature. Manure CH 4 emissions can be the largest contributor to the carbon footprint of pork production. Despite the importance of CH 4 , its actual emissions in cold temperate climates are highly uncertain. This study measured emissions from a single-cell earthen manure storage facility at a commercial swine farm near Brandon, Manitoba, Canada, for 3 yr. Complimentary laboratory measurements were done to assess CH 4 potential (B 0 ). The manure storage regularly received manure from the barn and was only emptied in October. In the summer, manure temperature was usually lower than the air temperature, with the manure temperature (averaged across depths) warming to between 15 and 18.5 ˚C for only 9 wk. Emissions of CH 4 were low, with the CH 4 conversion factor being between 3.0 and 11.0%, depending on the year (using the IPCC 2019 default B 0 ). Scaled by the number of swine reaching market weight (125 kg) each year, CH 4 emissions were between 250 and 902 g CH 4 animal −1 . Laboratory measurements of CH 4 production potential scaled by VS were 335 ml CH 4 g −1 VS at 37 ˚C, perhaps lower than the IPCC 2019 default value due to barley (Hordeum vulgare L.) in the ration and degradation in the under-barn pit prior to transfer outdoors. Taken together, the low manure temperatures, short warm season, and barley in the ration suggest that emissions from swine manure in cold climates like western Canada are considerably lower than previously estimated based on default factors.

“…We fed diets based on either 64.4% wheat or 67.6% barley grain providing 9.6 or 10 MJ NE/kg to weaned pigs. Feeding barley-instead of wheat-based diets reduced dietary energy digestibility but increased growth performance (Figure 2; Zhou et al, 2016b). (Zhou et al, 2016b).…”

With the increase in global human population, people living longer, and relocating from the countryside to urban centres, it is expected that the demand for animal food products will increase. Animal production competes with humans for basic grains. However, humans only consume ~30% of crops directly, therefore animal production is mostly complementary. This overview with a Canadian perspective provides a superficial look at on how we use non-food cereals, oilseeds, pulses and their coproducts and fractions to sustainably convert them into edible protein for human nutrition reducing waste streams. Feeding low-grade grains and coproducts may indeed increase the environmental footprint of animal agriculture. Nonetheless, it is undeniable the role ruminant and monogastric animals play in converting inedible plant material and coproducts into wholesome meat, milk, and eggs. Finding what to feed that is locally grown or sourced, even thought it may be of limited quality and(or) availability, seems a daunting challenge despite that it reduces feed cost and supports the local economy. We should evaluate diets more based on what non-human edible coproducts are included that could become meat, milk, and eggs for human nutrition rather than placing great emphasis on animal performance parameters. Fear of antinutritional factors and mycotoxins on animal performance limits our feed cost advantage. Increased feed and food safety risk is indeed part of getting more out of compromised feedstuffs to reduce waste. Policy changes are required to embrace a circular bioeconomy that would contribute to prevent climate crisis.

“…Hermes et al (2009) também verificaram aumento do ganho de peso e no peso final, menor incidência de diarreia e intervenções com antimicrobianos nos animais que receberam a associação de 20% de proteína bruta com 2% de polpa de beterraba sacarina e 4% de farelo de trigo em leitões avaliados a partir de 35 dias de idade (desmamados aos 21 dias e 14 dias de adaptação à dieta). E, Zhou et al (2016) reportaram que a inclusão de bagaço de cevada (65,6% e 62,3%) em substituição ao farelo de trigo (67,5% e 64,4%) também melhorou o desempenho dos animais avaliados a partir dos 32 dias de idade, apesar da redução na digestibilidade e na energia da dieta.…”

“…A inclusão de cevada na dieta dos animais aumenta a quantidade de fibra, e por consequência, pode aumentar o tamanho do trato gastrointestinal, potencialmente aumentando sua capacidade e o consumo de ração (HETLAND et al, 2004;MATEOS et al, 2006;GERRITSEN et al, 2012;ZHOU et al, 2016 A maior incidência observada neste estudo pode ter ocorrido, uma vez que, logo após o desmame os leitões são submetidos à diversos fatores estressantes, tais como: ambientais e de manejo (separação da matriz, transporte para os galpões de creche, mudança do tipo de instalação), sociais (estabelecimento de uma nova hierarquia devido à mistura de lotes e origens) e nutricionais (substituição de uma dieta em grande parte líquida por uma dieta sólida e menos digestível). Todos esses fatores associados à reduzida proteção advinda da imunidade passiva, tornam o leitão desmamado susceptível aos agentes oportunistas, e a ocorrência de diarreia (CAMPBELL, et al, 2013;MOESER et al, 2017).…”
