Read this excerpt of an article of The New
York Times:
Breast Milk Is Teeming With Bacteria — That’s Good for the Baby Breast-fed milk may nourish a baby’s microbiome in ways that bottled breast milk can’t.
In the earliest days after birth, millions of bacteria make their home in a baby’s body — in the skin, mouth and especially the gut. These immigrants come from the birth canal and the mother’s feces (during a vaginal birth), the mother’s skin and mouth as she holds and nuzzles the baby and perhaps even from the placenta, although that source is still debated. The colonizing microbiome can have a farreaching impact on the baby’s health. Studies have suggested, for instance, that the populace of a baby’s microbiome in the first two years of life may predict later risk of obesity. Children born by cesarean section are also more likely to become obese, or to develop autoimmune diseases such as type 1 diabetes and asthma. Lately, scientists have identified another major contributor to the infant microbiome. Breast milk, it turns out, is teeming with bacteria that colonize the infant’s gut, and could help set the course for the baby’s growing immune system and metabolism.

Read the following excerpt:
“Three nights later old Major died peacefully in his sleep. His body was buried at the foot of the orchard. This was early in March. During the next three months there was much secret activity. Major's speech had given to the more intelligent animals on the farm a completely new outlook on life. They did not know when the Rebellion predicted by Major would take place, they had no reason for thinking that it would be within their own lifetime, but they saw clearly that it was their duty to prepare for it. The work of teaching and organising the others fell naturally upon the pigs, who were generally recognised as being the cleverest of the animals. Pre−eminent among the pigs were two young boars named Snowball and Napoleon, whom Mr. Jones was breeding up for sale. Napoleon was a large, rather fierce−looking Berkshire boar, the only Berkshire on the farm, not much of a talker, but with a reputation for getting his own way. Snowball was a more vivacious pig than Napoleon, quicker in speech and more inventive, but was not considered to have the same depth of character. All the other male pigs on the farm were porkers. The best known among them was a small fat pig named Squealer, with very round cheeks, twinkling eyes, nimble movements, and a shrill voice. He was a brilliant talker, and when he was arguing some difficult point he had a way of skipping from side to side and whisking his tail which was somehow very persuasive”.
