Impact of sodium acetate and sodium succinate supplemental to rations of lactating goats on milk production, milk composition and some ruminal and blood parameters [electronic resource].

Includes references.

Effect of including sodium acetate or sodium succinate and their combination in the lactating goats rations on dry matter intake, milk yield and composition, feed efficiency and some ruminal and blood serum parameters were studied. Twelve lactating baladi goats in early lactation were divided into four groups using 4x4 Latin square design with 30 day periods. The control diet (C) used consisted of berseem hay as source of roughage and concentrates (40:60%, dry matter basis). The three experimental diets used were: control diet plus 300 mg/Kg live body weight ( LBW) of sodium acetate (T₁), control diet plus 7 mglkg LBW of sodium succinate (T₂) and control diet plus 300 mg/kg LBW of sodium acetate + 7 mglkg LBW of sodium succinate (T₃). Dry matter intake (DMI) differed significantly (P<0.05) among treatments, where intake was reduced (P<0.05) by adding the supplements. Milk yield and 4% FCM were significantly (P<0.01) higher in treated groups compared with control. Yields of milk contents were also higher (P<0.05) in treated groups. TS and SNF contents were higher (P<0.05) in treated groups, however, Fat, TP, Lactose and ash contents were not differed significantly among treatments. Feed efficiency (gig) calculated as milk yield IDMI and FCM/DMI were better in TJ than the other treatments and control. Ruminal pH, TVFA's, TN, true-protein nitrogen, NPN and NH₃-N values were slightly higher in treated groups. There were significant (P<0.05) effects due to sampling time among different values of rumen parameter investigated. Serum TP, globulin and urea were slightly increased (P>0.05) with treated groups. Serum glucose increased significantly (P<0.01) with inclusion the combination of sodium acetate and succinate (T₃) in the diets.
