Responses of lactating dairy cows to sodium bicarbonate or sodium bentonite in low forage diet

Abstract

Dietary sodium bicarbonate or sodium bentonite has been used in lactating cow diets to aid ration adjustment. Addition of sodium bicarbonate increased intake and milk production for cows fed high concentrate diets in the first two months after parturition (Erdman et al., 1980). Addition of dietary buffers such as sodium bicarbonate and sodium bentonite increased molar percentage of acetate and reduced propionate in dairy cows. Milk fat percentage was increased by sodium bicarbonate in dairy cows when fed low roughage diets (Erdman, 1988). The objective of the present study was to investigate the effect of sodium bicarbonate or sodium bentonite in diets of high yielding dairy cows on milk yield, milk composition, and faecal pH.

Effect of Supplementation Dry Yeast or Bentonite and their Combination as Feed Additives on Productive Performance of Lactating Buffalos.

“…Bentonite is one of the common natural clays used in animal diets to improve feed intake, digestibility of nutrients and daily gain (Saleh et al, 1999 andSalem et al, 2001). Mesgaran (2005) indicted that addition of sodium bentonite (350 g/cow/d) to the low forage diet slightly enhanced milk yield of Holstein cows. Katsoulos et al (2006) found that when cows were fed on concentrate ration supplemented with 1.25% clinoptilolite could be produced higher total milk yield than the unsupplemented ones.…”

Effect of Toxin Binder on Productive Performance of Lactating Friesian Cows

“…More recently, Sulzberger et al (2016) pointed that when dairy cows fed on TMR with high grain challenge and supplemented with 0.5, 1 and 2% clay (on DM basis) milk yield tended to increase than the unsupplemented once. Mesgaran (2005) found that the addition of 305g sodium bentonite/cow/day to the low forage diet slightly enhanced milk yield of Holstein cows. Abd El-Baki et al (2001) studied the effect of clays on animal nutrition and some physiological blood parameters.…”

“…The additives of Bentonite were safety for feeding livestock as 20 mg/Kg intake DM for all animal species (EFSA, 2013). On the other hand, Mesgaran (2005) showed that addition of 350 g bentonite/cow/day to the low forage diet slightly improved the production performance specially milk yield of Holstein cows. Katsoulos et al (2006) found that when cows fed on concentrate ration supplemented with 1.25% clinoptilolite could be produced higher total milk yield than unsupplemented diets.…”
