Explanation:
Detailed explanation-1: -Sheep are ruminants (they have four stomachs). As sheep graze, they eat quickly, only chewing their food briefly, mixing it with saliva before swallowing. The first stop in the digestive process is the rumen (first stomach). The rumen contains digestive juices and millions of microbes that start to break down the food.
Detailed explanation-2: -The net energy for growth (NEg) values for varying average daily gain (100–350 g) in ram lambs grown from 35 to 50 kg increased from 1.31 to 5.93 MJ/d with an energy efficiency for growth (kg) of 0.457.
