Effect of propylene glycol on fertility of postpartum dairy cows experiencing seasonal heat stress
The objective of this study was to evaluate effects of a daily oral drench of Propylene Glycol (PG) on fertility in dairy cows experiencing seasonal heat stress. In treatment group, cows (n=9) were treated with drenching 250 ml propylene glycol once daily from 3 to 15 days post-partum following the morning milking. Another group of cows (n=9) was selected as untreated control. The serum beta-hy...
متن کاملEffects of feeding dry propylene glycol to early postpartum Holstein dairy cows on production and blood parameters.
In all, 18 multiparous and 19 primiparous Holstein dairy cows were used in a completely randomized design with restrictions to evaluate the effects of feeding propylene glycol (PG) as a dry product, via two delivery methods, on production and blood parameters. PG treatments were administered from parturition through 21 days postpartum. Treatments were: (i) control, no PG; (ii) top dress, 162.5 ...
متن کاملNutrition and fertility in dairy cows.
Introduction It is now widely recognised that reduced fertility in dairy herds is one of the most important factors affecting producer profitability. Roche (2006) has defined the effect of infertility on profitability as: (i) prolonged calving interval with fewer calves and less milk per cow; (ii) increased replacement costs; (iii) increased labour, semen and veterinary bills; and (iv) an exten...
متن کاملMaize silage for dairy cows
This paper reviews the use of maize silage in pastoral dairying systems in New Zealand. The evolution of dairying systems to make profitable use of maize silage and other supplementary feeds has occurred during the last decade in conjunction with an increased use of maize silage. When used within recommended levels of feeding, maize silage provides a low cost source of starch and fibre which co...
متن کاملGlycerol Supplementation in Dairy Cows and Calves
The production of biodiesel from rapeseed oil methyl ester leaves glycerol (synonym: glycerine, 1,2,3-propanetriol) as a valuable by-product and a promising feed supplement for farm animals. This thesis provides information about the supplemental feeding with glycerol to dairy cows in early lactation and to young calves, and describes the fate of glycerol entering the rumen and the impact of gl...
