Source: adapted from different types of literature [56, 57]. Note: TAC = total animal class; TAUA = total animal unit annual. Total animal unit (TAU)/day, #/month, #/annual and correct proper use factor (30%) considered grazing of the Surra government plantation. Note: Animal Unit (AU) represents the dry matter intake (DM intake). in other words, it is the grass/fodder taken (grazed) by different animal classes. for example, animal classes represents a given animal with its corresponding weight that given by FAO (TLU) and America animal unit equivalent (AUE). Hence, TAUD represents total animal unit per day (total animal grass (DM) intake per day; TAUM (total animal class DM intake per month); and TAUA (total animal classes DM intake per annual). These leads to the total fodder production of the Surra government plantation. However, an animal class in a poor pasture like the Surra intake 2% (0.02) of its weight. The second issue is 30%. 30% represents the assumed uneaten (unpalatable) grasses that the Surra government plantation produces. Therefore, based on these information and the carrying capacity (that tell as the amount/number of animal classes) the grass/fodder production podetial per hectare per annual and the entire forest were quantified. Hence, 789.1 is total single animal classes DM intake per day; for instance, cow dry + cow with calf + ...); 23673 represents the total single animal classes DM intake per month (789∗30 days); 312 represents a number of animal classes, for instance, animal class of cow dry is 63 in number, cow with calf is 64 in number, and so forth. 312, 714 is for example, total animal unit annual (total animal classes DM intake per annual, and deducted 30% of it in order to deduct the uneaten or unpalatable grasses).
