Milk product obtained from other mammals for consumption by humans of all ages. In almost all mammals, milk is fed to infants through breastfeeding, either directly or by expressing the milk to be stored and consumed later. The early milk from mammals is called colostrum. Colostrum contains antibodies that provide protection to the newborn baby as well as nutrients and growth factors. The makeup of the colostrum and the period of secretion varies from species to species. For humans, the World Health Organization recommends exclusive breastfeeding for six months and breastfeeding in addition to other food for at least two years.
Invariant of a binary form is generated by these two invariants together with the form "f" of degree 1 and order 4, the Hessian "H" of degree 2 and order 4, and a covariant "T" of degree 3 and order 6. They are related by a syzygy "jf"−"Hf""i"+4"H"+"T"=0 of degree 6 and order 12. The algebra of invariants of a quintic form was found by Sylvester and is generated by invariants of degree 4, 8, 12, 18. The generators of degrees 4, 8, 12 generate a polynomial ring, which contains the square of Hermite's skew invariant of degree 18. The invariants are rather complicated to
