The eggs float freely with the currents until hatching. The larvae drift in oceanic waters or in the outer shelf for a period of 4–8 weeks until they metamorphose and develop barbels.

[85] The eggs develop in utero for about 28 days, with only about 10 days of external incubation (in contrast to a chicken egg, which spends about one day in tract and 21 ...
The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [1] The rumen and the reticulum make up the reticulorumen in ruminant animals. [2]The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically indigestible by mammalian digestive systems.
Goats produce about 2% of the world's total annual milk supply. [62] Dairy goats produce an average of 540 to 1,180 kg (1,200 to 2,600 lb) of milk during an average 284-day lactation. [63] The milk can contain between around 3.5% and 5% butterfat according to breed. [64] Goat milk is processed into products including cheese [65] and Dulce de ...
