Note:
(a) "AT FIRST the calf’s front hooves appear, then disappear from view again, as the cow stoically pushes and the contractions get faster. The head follows and then the shoulders, the broadest part of the newborn and the most uncomfortable moment for its mother. Visitors can watch the birth, which usually takes an hour"

(b) "Fair Oaks Farms, one of America’s biggest and most modern dairy operations. It is also the country’s only dairy theme park (though many other farms are open to the public). * * * cows step onto a slow-motion merry-go-round to be milked three times a day."

(i) Rather than cow's natural gas (my imagination), presumably CNG stands for compressed natural gas.

(c) "Children can * * * ascend 'udder heights' on a 25-foot milk bottle"

(iii) Many suburbs of Cleveland, Ohio have “Heights” as the second word.

(d) Mr McCloskey, a co-owner, "is now looking at what to do with this tea-coloured liquid [from manure after anaerobic digestion]. One idea is to try to make it drinkable by using duckweed 浮萍 [biologically: the subfamily Lemnoideae] to absorb the remaining nitrogen and phosphorous. The weed could be used as a feed high in protein for the cows."
