Influence of propylene glycol and glycerin in Simmental cows in periparturient period on milk yield and metabolic changes

Abstract

Abstract. The aim of this study was to compare the influence of propylene glycol and glycerin added to Total Mixed Ration (TMR) dose on lipid-carbohydrate metabolism, activity of selected liver enzymes and milk yield of Simmental cows in periparturient period. Forty two cows of Simmental breed were divided into 3 groups (n=14). Cows from the experimental groups were given 300 ml/d of either propylene glycol or glycerin from 7th day prepartum to 21st day postpartum. In week 5 of lactation in cows that were given propylene glycol and in week 12 in cows receiving glycerin Body Condition Score (BCS) was higher as compared to control cows. An application of glycerin resulted in the highest milk yield. Higher glucose content in groups that were given propylene glycol and glycerin would have contributed to the reduction of negative energy balance at the beginning of lactation. The lowest increase in aspartate transaminase (AST) and bilirubin level was observed in cows receiving glycerin. The study demonstrated that metabolic changes in Simmental breed cows in the periparturient period are dramatic, and an application of glucogenic precursors may improve metabolic efficiency.

The comparison of propylene glycol and glycerol as feed additives in early lactation of high producing dairy cows

“…The results of the experiment 1 confirm that glycerol can be as effective as propylene glycol in prevention of ketosis. Similarly, other authors did not find significant differences in the intensity of energy metabolism disturbance between propylene glycoland glycerol-groups of dairy cows (Staufenbiel et al, 2007;Adamski et al, 2011). On the basis of our results, a higher dose of glycerol did not improve energy metabolism in comparison with an energetically lower dose of propylene glycol.…”

“…The results of experimental work with supplementation of glycerol and propylene glycol in fresh cows differ. Lomander et al (2012) did not find a positive effect of glycerol or propylene glycol in Swedish dairy herds, but Adamski et al (2011) found beneficial effects of ABSTRACT. The aim of this study was to compare the antiketogenic effect of glycerol and propylene glycol after parturition.…”

Effect of Propylene Glycol and Calcium Propionate on Some Morphometric, Productive, Reproductive and Metabolic Parameters in Drenching Egyptian Water-Buffalo Heifers

“…At calve birth, there was a significant (P<0.05) increase in PG and CP treatment than control group but the increase was better in CP treatment groups fed 300g CP dissolved in 3L saline solution containing (0.9 NaCl) than those PG treatment and control group. The same trend was obtained in live body weight and changes in LBW at calve birth (kg) with MaciejAdamski et al, (2011) and Abdel-Latif et al, (2016).They published that feeding propylene glycol by using 18 primiparous Egyptian buffalo that were selected during the last pregnancy at the end of 8 weeks of gestation and the period of early feeding with an average of 500± 25kg vivo and age 35± 5 month to evaluate the effect of PG and CP treatment group for animals fed experimental group. The animals were divided into 3 similarly groups (6/each) based on LBW, the animals were drenched 3 liters of saline solution (0.9% NaCl) without any other supplements; whereas in the second groups' animals (PG) were given 300ml of dissolved PG was drenched in 3 liters of saline solution, and in the third CP group, animals were supplemented with 335g of dissolved CP in 3 liters of brine.…”

“…They found that using propylene glycol administration improved the body weight. Also, when feeding the PG originally drenched, the BCS and LBW was higher than the control group (MaciejAdamski et al, 2011 andAbdel-Latif et al, 2016).…”

The effect of replacing soybean oil with glycerol in feeding mixtures designed for utility layers on their production and state of health

“…It was found that raw glycerol (obtained from the production of bio-oil) could be included in a diet of layers at a level of 6 %, without producing any negative effect on egg production, egg quality and the retention of nutrients and metabolized energy (ME d ). The use of dietary glycerol in ruminants was studied by Adamski et al (2011), its use in monogastric animals by Suchý et al (2011). The use of glycerol in feeding mixtures will excite more attention with further developments in the production of bio-oil.…”
