Agribusiness: how to eat meat without harming animals.
What if you could eat chicken nuggets without harming a chicken? It's possible through "cellular agriculture," says Isha Datar. In a talk about cutting-edge science, she explains how this new means of food production makes it possible to eat meat without the negative consequences of industrial farming, and how it could fundamentally change our food systems for the better. "It's our once-in-a-lifetime opportunity to get a second chance at agriculture," she says.

Agribusiness : How to calculate dressing percentage in slaughtered cattle.
Cattle business is no doubt profitable but you can actually calculate the profit if you track the numbers, yes! do the math.
Cattle business can be broadly divided into:1) sale of live animals. 2) buy the animal, fatten and sell. 3) buy, slaughter and sell.
How do you calculate the meat to expect from the carcass ? many people believe that the live weight of the animal is what to expect when animal is slaughtered. A lot of people are often surprised at quantity of meat after processing because dressing percentage is different from live weight.
The concept of dressing percentage is key to profit calculation in cattle business, this is the math critical to business evaluation.
What is dressing percentage and how do you do the math? The dressing percentage is the portion of the live weight that results in hot carcass weight.
What is the hot carcass weight? this is the weight of the unchilled carcass after the head,internal organs and hides have been removed. The hot carcass weight for cattle is approximately about 60-64% of the live animal weight. The hot carcass weight can vary from one animal to another depending on some factors.
The dressing percentage = hot carcass weight / live weight X 100.
If an animal weighs 300 kg, working with 62.5% as hot carcass weight means the dressing percentage will be: 187.5 /300 X 100= 62.5.
The dressing percentage used in the meat industry does not equate to amount of beef that will be available for sale because the carcass will be divided into various meat cuts.
The whole animal is cut into halves and separated into front and hind quarters. These quarters are separated into primal cuts ,this is referred to as breaking down the carcass. The amount of beef available can be affected by amount of fat in carcass which will be trimmed off or the size /weight of bone because bone can weigh more.
The more bone is left in the beef cut the higher the yield percentage but when retail cuts are boneless then the percentage yield will be lower.
This calculation is a template to determine profit whether you are supplying beef using different cuts or you are selling retail.

Food safety: Global call to reduce antimicrobial use in healthy animals.
World leaders have called for an urgent reduction in the amount of antimicrobial drugs, including antibiotics, used in food systems.
The Global Leaders Group on Antimicrobial Resistance said countries must stop the use of medically important antimicrobial drugs to promote growth in healthy animals.
Antimicrobial drugs are also given to animals for veterinary purposes to treat and prevent disease.
Mitigation measures
A top priority is to reduce the use of drugs that are of the greatest importance to treat diseases in humans, animals and plants.
Antimicrobial resistance (AMR) in bacteria can make foodborne infections such as Campylobacter and Salmonella harder to treat. Experts said climate change may also be contributing to an increase in AMR.
“We need urgent action to win the race against AMR. The longer the world delays, the greater the costs will be, in terms of costs to health systems, costs to food systems, costs to economies, and costs in lives and livelihoods,” he said.
“We need to invest in human health, animal health, plant, food and environmental eco-systems to properly respond to the growing threat of AMR. Many countries have national action plans on AMR but too few are funded for implementation.
