Excess temperatures cause low flocking concerns

A study found that days above 32°C during the mating week caused a 2.1 million fewer lambs produced in Australia each year. If global warming increases by 1°C or 3°C, annual losses could increase to 2.5 million and 3.3 million, respectively. The research also found that heat stress can reduce lamb birthweight by 0.6-1.4kg.

Fish fed to farmed salmon should be part of our diet, too, study suggests

A recent study by the University of Cambridge found that farmed salmon production leads to a loss of essential nutrients. Consuming one-third of current food-grade wild feed fish directly could maximize nutrients from the sea. This approach could help address global nutrient deficiencies and improve both diets and ocean sustainability.
