EXERCISE

1. A cow weighing 400 kg and yielding 10 litres of milk with 4% fat has  consumed 40 kg green fodder having a DM content of 20% and excreted on an average 20 kg of faeces with a DM content of 15%. Calculate the amount of Dm digested and the digestibility coefficient of dry matter?
2. A buffalo has consumed 30 kg of green fodder having a CP contenet of 1.6% and excreted on an average 20 kg of faeces with a CP contenet of 0.9%.Calculate the digestibilty coefficient of CP of the green fodder?
3.  A sheep consumed 0.95 kg of cowpea hay (moisture 11%) and voided 1.25 kg of faeces (moisture 60 %). Calculate the dry matter (DM) digestibility of hay. CP of hay and faeces are 9.4 % and 8.5 % on DMB respectively. Calculate the digestibility of CP of the cowpea hay.
4.  In a digestion trial, a steer was fed with 7 kg of hay and excreted 13 kg of faeces (As such basis). The daily intake and excretion of proximate composition of hay is given below. Calculate the percentage of digestibility coefficient of the nutrients and TDN
