RVC 28 - Dietary Fatty Acids and Fertility of Humans and Animals
We’re constantly told that too much fat in our diet is bad for the health of ourselves and our animals. However it now seems that very particular types of fats are implicated in determining not only animal health but their reproductive performance. Here Dr Robert Abayasekara and Prof Claire Wathes of the Department Of Veterinary Basic Sciences at the RVC explain their work demonstrating the effect of different polyunsaturated fatty acids (PUFAs) on human and animal fertility.

6.4.2 Manufacturing the boat

Filling the mould is a serious problem in injection moulding: the lower the MFI, the more difficult it is to push molten polymer down narrow tubes into a metal mould. The engineers at Rolinx, the trade moulders who initiated the thermoplastic project, were working at the limits of their machinery in moulding such large objects in one operation. In the event, they were forced to blend the low MFI copolymer grade with a higher MFI grade material (GY702M) in order to achieve their objective (

5.1 The medical background

Blood pressure is normally tightly controlled in the face of large variations in blood flow required by activities such as vigorous exercise. The diameter of the blood vessels is under the influence of the so-called sympathetic nervous system. Impulses from the brain stimulate the release of a chemical substance, noradrenaline (1), from the nerve-endings close to the vessel walls. The noradrenaline then diffuses to the blood vessel wall, where it interacts with a specific molecular sit

7.1 Hierarchies of ideas

A useful way of giving sense and structure to ideas can sometimes be to see them in the form of a hierarchy. At one end is the ‘big picture’ (e.g. general context, principles, theories, ideas, concepts) and at the other end are particular facts, examples and other details. For example, the concept of living things contains the category of animals and plants. Animals contains the category of mammals, which contains the category of dogs, which contains the specific type of dog called Dalmat

5 Conclusion

Domesticated organisms evolve in artificial environments under artificial selection, and opportunistic or enforced hybridisation often occurs between species that would not normally interbreed. Natural selection cannot be eliminated and continues to operate. At least two different forms of dwarfism are common in domesticated livestock and humans, but only the rarer midget type of dwarfism occurs in wild lineages. Domesticated mammals and birds have distinctive patterns of skin pigmentation th
