The possibility to use genetic selection as a strategy to combat infectious diseases in livestock has been recognized by animal breeders for a long time [1,2]. In 1997, Bishop and Stear [3] showed that the potential to breed against nematode infections is greater than predicted by common quan...
Individually, those animals can learn over time to adapt to the new environment. However this period can take some time to occur. It’s also important to remember than behavioural adaption is not a heritable trait. To some degree, cattle have to learn from one another in order to express t...
the team of international scientists discovered that under certain circumstances the females would choose a male from different species that had similar colouring to males from their own species. They also found that when the light conditions are poor, the females could not distinguish between males ...
In addition, since they are a highly coveted breed, keeping them indoors can help protect them from potential dangers like catnappers who might want to use them in cat cage fights and other risks like car incidents, predators, and harsh weather. If you’re looking for a loyal companion that...
some breeders have attempted to force matings of different species by confining them in small cages. This would put an unreasonable amount of stress on the individuals involved and compromise their welfare. The resulting eggs have a low probability of fertility, and those that hatch are unlikely ...

Weighing only 0.9 to 2.7kg, the Chihuahua is the smallest dog breed across the world. Originated in Mexico, Chihuahua got its name from the Chihuahua state in its origin country. With a small rounded head, rounded eyes and erect ears, they are found in different patterns and colors. You ...
As a result, it’s often prescribed for animals with upset stomachs, especially when paired with plain, boiled chicken. It has a fair amount of carbohydrates, though, so you should only serve it in moderation, and it should be avoided for dogs with diabetes. 29. Dairy You have to give ...
Recent research has shown that domestic animals can discriminate human facial expressions13,14. Some research has also demonstrated that captive wildlife can recognize human faces15, while it is still unknown whether non-primate wildlife can discriminate the emotional facial expressions of humans. Giant...
by an animal between subsequent locations. Such highly resolved paths allow more detailed investigations of the precise paths taken by animals and how the costs of moving across different habitat features may shape these. High resolution GPS and IMU sensors offer different yet complementary information...
