14/06/2017: Heat stress could be underestimated in swine: European state of play and new study on live yeast benefits

Survey of heat stress risks in farrowing rooms in Europe. Average daily percentage of time spent above 25°C (significant heat stress) and estimation of the associated feed intake reduction (Lallemand Animal Nutrition internal data, 2016).

 In the summer, lactating sows could spend 34 to 94 percent of their time above heat stress threshold (25°C), which could lead to 0.6 to 2.5 kg per day of reduced feed intake, and this is true from Netherlands to Spain. 

 These are the findings from an initial survey conducted by Lallemand Animal Nutrition in order to evaluate the reality of heat stress in the farrowing rooms across Europe. The consequences for the sow and the farmer range from discomfort to reduced body weight and reproduction issues. 

 Recent trial (INRA Pegase, France, unpublished) confirms that the use of probiotic yeast S. cerevisiae boulardii I-1079 in feed, known to help control digestive process and performance under challenging conditions, could contribute to adaptation to heat stress. The study was performed by E. Labussière and his team at IINRA Pegase, using state-of-the-art experimental facility to study energy balance and metabolism under controlled conditions. 

 They used finishing pigs as a model for swine and sows, (the bigger the animal, the more sensitive to heat stress). Results indicate that LEVUCELL SB had a positive effect on growth performance under both thermo-neutral and heat stress conditions. However, the supplementation had a greater impact under heat stress as it was able to “compensate” for the negative impact of high temperature on pig growth. 

This could be linked to two effects of the supplement:

• Improved feeding behavior: The number of meals per day was significantly improved under heat stress and the total daily feed intake was not affected by ambient temperature with LEVUCELL SB. 
• Positive effect on energy metabolism: Less energy is consumed for heat production, therefore more energy was made available for pig growth. 

 Farm trials conducted with sows in maternity pen confirm similar benefits in sows in field conditions: improved sow feed intake, reduced body weight loss in lactation, translated into increased piglet pre-weaning average daily gain (ADG), and even reduction of piglet neonatal diarrhea. 

 Hence, LEVUCELL SB could represent a valuable tool to help alleviate the heavy toll of heat stress on pig production, in complement to relevant heat abatement strategies in the barn.

14/01/13: Climate change and wheat; Indian wheat exports set to boom; Lallemand buys Aviguard business

• Over the last 50 years developments in agriculture have improved yields. However, it's feared that increasing heatwaves will undo this progress. A study on corn grown in France predicts losses of up to 12 percent for maize yields in the next 20 years. A second study says that, without action against climate change, wheat and soybean harvests will fall by up to 30 percent by 2050 as the world warms. Read more...

• Although much of the world has suffered from a slow down in grain exports in 2012, due in part to bad weather, India has fared much better. The country is set to triple its wheat exports to a record six million tonnes in 2013. Over the last five years India farmers have stockpiled large quantities of grain which will help plug the global shortfall in lower-quality grain. Read more....

• Lallemand Animal Nutrition has announced that it acquired Microbial Developments Ltd, the UK based manufacturer of Aviguard, on December 31, 2012. Aviguard is a well established avian competitive exclusion product that aids the rapid establishment of normal gut flora in day old chicks thereby minimising colonisation by transient pathogenic bacteria such as Salmonella, E. Coli and Clostridium perfringens. Aviguard is sold in over 36 countries and is widely used in broiler and layer breeders, parent and grandparent stock. Yannig Le Treut, general manager of Lallemand Animal Nutrition says, “Aviguard is a well established and cost effective competitive exclusion solution used by many of the world’s leading poultry breeders and integrators to help prevent the colonisation of the gut by salmonella and other pathogenic bacteria. With ever increasing consumer and regulatory pressures on the poultry industry to minimise the routine use of antibiotics, we believe Aviguard is well positioned for the future and will complement our existing portfolio of poultry products,  which includes Bactocell, Alkosel, Agrimos and Levucell SB”.
