Heat stress is a critical issue in modern poultry production. Farm management and equipment used in hot weather must be adapted to reduce the negative impact of heat stress on productivity. The main changes that producers can implement at farm level are the nutritional management and feeding strategies. In addition to these strategies, commercial yeast products […]
Background The decision to calve heifers earlier is essentially an economic one based on the aims of reducing rearing costs (principally feed and housing) and bringing forward the age at which milk can be sold. A calving age of 23 to 24 months achieves these aims without compromising lifetime milk production. An average daily growth […]
Pig farm managers are well aware of the new performances allowed by modern sows. They are also witnessing management changes in sow nutrition to par with the corresponding metabolic and colostrum/milk production evolutions. What is less commonly realised is that the litters born to these modern sows are also composed of modern piglets. A bibliographic overview shows that newborn and suckling piglets’ management is about to drastically specialise.
The innate immune system acts as an alarm that senses danger in the form of infection and/or cell damage, and helps to initiate recovery and repair processes. Integral to innate immune cell activation are germline-encoded pattern recognition receptors that sense danger in the form of exogenous microbe-associated molecular patterns and endogenous damage-associated molecular patterns. Innate […]
In 2013, aquaculture production in Brazil reached 387,7 MT. Since 2003, production is growing at an average rate of 9.3% (FAO, 2014). Aquaculture production is spread to all geographical regions in Brazil, but the Northeastern accounts for more than ¼ of the total (Fig. 1). There are three major aquatic animal groups farmed in the […]
