“…It is worth mentioning that, the beneficial effect in GPG250 is mainly due to PG supplementation. These findings was supported by the results of Pechova et al [45] who found that, there was no beneficial effect to glycerol above 500-1000 mL. Also, they reported that 500 mL of glycerol was effective as 300 mL propylene glycol.…”

A total of 108 Holstein cows were used to evaluate the effect of drenching propylene glycol (PG) either individually or in combination with glycerol (G) on body condition score (BCS), production, reproductive performance, protection against subclinical ketosis and economic benefit of dairy cows during the transition period. The six groups (n = 18/group) were; Control group, cows received no treatment; PG300, cows were drenched 300 mL PG for 7 days pre-expected day of calving and 21 days post-calving; PG400, cows were drenched 400 mL PG for 7 days pre-and 7 days post-calving; PG500, cows were drenched 500 mL PG for 10 days pre-and 10 days post-calving; GPG150, cows were drenched a mixture of 150 mL G and 150 mL PG for 21 days pre-and 21 days post-calving; GPG250, cows were drenched a mixture of 250 mL G and 250 mL PG for 21 days pre-and 21 days post-calving. BCS at 30 days in milk (DIM) was significantly higher in all treated groups in comparison to the control one and the best values were observed in GPG250, GPG150 and PG500 groups. Lactation length (LL) was significantly (p < 0.001) shorter in GPG250, GPG150 and PG500 groups than control group. There was a significant increment in 305 milk yield (p < 0.001) and average daily milk yield (p < 0.001) in GPG250 and PG500 groups than other groups except for PG300 with the lowest values for control and PG400. Cows in all treatment groups were observed in heat and conceived earlier as well as had shorter open days and calving interval durations (p < 0.001) and low number of services per conception (p = 0.004) compared to control group with better results for PG500 and GPG250 groups. BHB level and percentage of cows suffered from subclinical ketosis at 7 DIM was significantly lower in GPG250, GPG150 and PG500 groups than control group. Cows in treatment groups had a significantly higher glucose level (p = 0.006) compared to control group. Regarding to economics, the control group showed the highest feed costs, insemination costs and total costs per animal. Additionally, control and PG400 groups had the highest cost per kilogram of milk from total and feed costs compared to other cows. PG300, PG500 and GPG250 groups recorded a greater net return and income over feed cost (IOFC). In conclusion, the continuous drenching of propylene glycol either individually or in combination with glycerol regimens for long duration (PG300, PG500, GPG150, GPG250) during the transition period of dairy cows may reduce the incidence of subclinical ketosis and consequently improve milk production, reproduction and economics compared to drenching for short duration (PG400).

“…Besharati and Taghizadeh (2011) confirmed that PG caused a significant and marked increase in the rate and extent of ammonia production in the rumen. The improvement benefit of the effect of PG supplementation in this study is consistent with some other results (Madibela et al, 2006, Besharati and Taghizadeh, 2011, Pechová et al, 2014and Ferraro et al, 2016, but contrasts to other report (Kristensen and Raun, 2007) revealed the lowest acetate values in blood plasma flow in hepatic artery (2.48 mmol/h) in PG cows compared to control cows (3.01 mmol/h). However, these authors noticed that propionate (131 and 77 mmol/h) and butyrate (28 and 41 mmol/h) in blood plasma flow in hepatic artery of PG and control cows were in agreement with the present results, respectively.…”

To evaluate the effects of propylene glycol (PG as powder) on some nutrition parameters (digestion coefficient and nutritive values) and some productive parameters (milk yield and composition) and its effects on the quality of milk processing for Domiatti cheese). An experiment was conducted by eighteen lactating Zaraibi goats in 3 rd lactation season with an average body weight of 36±5.46 Kg and aged 39 months. In this experiment, three treatments were employed as six does in each treatment. The treatments done up to 21 weeks during lactation season and included: (1) control without PG (PG0), (2) 10g PG /doe/day (PG1) and ( 3) 20 g PG/doe/day. All treated goats were received basal ration contained 50% concentrate feed mixture (CFM) + 50% roughage (as berseem hay and rice straws) through lactation period up to 21 weeks. Apparent digestibility of CP, TDN and DCP was affected (P<0.05) by PG administration. Acetate and propionate were increased by using PG, but level of butyrate has increase significant for PG0. Moreover, the results could be showed that milk yield and milk compositions were affected (P<0.05) by the PG addition compared to control. Also, increasing PG levels from 10 to 20 g /does/day did not have any significant effect on milk yield, milk composition and other nutrition parameters. The cheese sample yield was slightly decreased particularly within PG1 and PG2 compared to PG0 cheese. The total solids and titratable acidity were slightly increased and pH values were slightly decreased by using PG milk. The PG cheese samples had significant (P<0.05) differences in TN/DM%, FA/DM% during the ripening period. The cheese made from PG1 and PG2 had the higher (P<0.05) score points for organoleptic properties than PG0 after continually storage period for 60 days. The results indicate that PG is an appropriate alternative for goats to prevent energy deficiency in the lactation period, while increasing the daily PG dose from 10 to 20 g has no significant but observed beneficial effect.

“…Quality of each diet component, as well as appropriate feed balancing show effect on the production capacity, milk composition, animal health [2] and their fertility [3]. In order to increase the milk productivity and animal health, liquid feed additives (energy additives) and feed concentrates are served to cows [4][5][6][7]. The liquid additives and feed concentrates can be delivered together with fodder or as an independent component.…”

Some needs to increase the efficiency of dairy production affect improvement of nutrition technology. In addition to constantly expanding the offer of liquid feed additives that complement nutrient deficiencies in the diet, manufacturers are introducing more and more innovative devices for dispensing them. The changing ambient temperature at which liquid feed additives are fed may affect their dispensing quality. Therefore the aim of this study was to determine the temperature effect of various liquid feed additives on the accuracy of their dosing in a feeding station for dairy cattle. To reach the aim of the study the test stand was built basing on the feeding station for dairy cattle. The test stand was equipped with a DeLaval membrane feeder GD 500. The operation of the feeder was based on the principle of the diaphragm pump. To determine the accuracy of dosing by the fodder membrane feeder the dosing accuracy indicator was determined. Three different liquid feed additives were used to check the inaccuracy of dosing. The tests were carried out for four different temperatures of feed additives. The highest mean value of dosing inaccuracy (about 10 %) was achieved with Glycol Plus at the temperature of 20 ºC. The results of the experiment showed the statistically significant effect of temperature and feed additive type on the dosing accuracy. As a result of the investigations it was found that in addition to the density of preparations changes in the accuracy of their dosage may be influenced by their other physical properties.
