Twenty-four multiparous Holstein cows were randomly allocated to a high DCAD (+100 mEq/kg DM; n = 12) or low DCAD (-100 mEq/kg DM; n = 12) 3 wk before calving.
ij] = effect of interaction between DCAD levels in pre-calving and postpartum; E[a.
01), in prepartum cows receiving DCAD of -100 mEq/kg DM and highest in cows receiving +100 mEq/kg DM (Table 2).
Feeding -100 DCAD diet resulted in higher (p < 0.
Feeding high DCAD diet to Thalli lambs might be an important nutritional tool to increase growth rate through increased DMI (Shahzad et al.
The experiment was planned to determine the effects of varying level of DCAD on growth performance of Thalli lambs.
The DCAD is the difference between milliequivalents of cation (Na, K) and anions (Cl, S) in the whole feed.
An increasing weight gain was observed with increasing DCAD level of the diet in growing lambs (Table 6).

The formulas shown in table 1 were used to calculate the DCAD and the electrolytic balance (EB) values.
Simple correlation coefficients (r) between observed DCAD and measured parameters, and regressions of observed DCAD on observed EB or of predicted on observed DCAD were conducted using the REG procedure in SAS .
Chemical composition and DCAD and EB values for forage species are summarized in table 2.
