Effects 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 کاملEffects of short dry periods on performance and metabolic status in Holstein dairy cows.
To evaluate effects of different dry period lengths on milk yield, milk composition, and energy balance of dairy cows, 122 multiparous and primiparous Holstein dairy cows were used in a completely randomized experimental design with 56-, 42-, and 35-d dry period lengths. Actual dry period lengths for respective treatments (TRT) were 56 +/- 5.1 d, 42 +/- 2.1 d, and 35 +/- 2.7 d. Overall, cows in...
متن کاملEffects of twin pregnancy and dry period feeding strategy on milk production, energy balance, and metabolic profiles in dairy cows.
The present study evaluated the interaction of pregnancy type [PT; single (S) vs. twin (T)] and dry period feeding management [D; close-up (CU) diet (NE(l) = 1.54 Mcal/kg of DM)] throughout the entire dry period (8W) vs. far-off (FO) diet (NE(l) = 1.32 Mcal/kg of DM) from 60 to 21 d before expected calving date (ECD) followed by CU diet until calving (3W). Treatments were arranged in a 2 x 2 fa...
متن کاملBlood metabolic profiles in Uruguayan Holstein and Uruguayan Holstein x New Zealand Holstein-Friesian dairy cows
Blood metabolic profiles were determined from 40 days prepartum to 60 days postpartum in Uruguayan Holstein (UH) (n = 13) and UH x New Zealand Holstein-Friesian first cross (UH-NZHF) (n = 13) cows with seven in each group experiencing their second lactation (L2) and six experiencing their third lactation (L3). Non-esterified fatty acids increased around calving and tended to be greater in UH-L3...
متن کاملeffects of feeding frequency and adding plant oil to diet on performance and feeding behavior of lactating holstein dairy cows
this experiment was conducted to investigate the effect of feeding frequency and oil supplementation to the diet on performance and feeding behavior of lactating dairy cows. twenty four lactating holstein cows, 12 primiparous, (bw= 626±58 kg and dim= 195±44 day) and 12 multiparous, (bw= 617±25 kg and dim= 207±39 day) were randomly assigned to four diets contained 2.5 percent supplemental oil or...
