Evaluation of propylene glycol and glycerol infusions as treatments for ketosis in dairy cows.

P Piantoni, M S Allen,

To evaluate propylene glycol (PG) and glycerol (G) as potential treatments for ketosis, we conducted 2 experiments lasting 4 d each in which cows received one bolus infusion per day. Blood was collected before infusion, over 240min postinfusion, as well as 24 h postinfusion. Experiment 1 used 6 ruminally cannulated ... Read more >>

Michael S Allen, Paola Piantoni,

The objective of this article is to discuss the effects of dietary carbohydrates on energy intake and partitioning as cows progress through lactation. Understanding how diet interacts with the physiologic state as it changes through lactation is critical to maximize productivity, efficiency of production, and health of lactating dairy cows. ...

Milk production responses to dietary stearic acid vary by production level in dairy cattle.

P Piantoni, A L Lock, M S Allen,

Effects of stearic acid supplementation on feed intake and metabolic and production responses of dairy cows with a wide range of milk production (32.2 to 64.4 kg/d) were evaluated in a crossover design experiment with a covariate period. Thirty-two multiparous Holstein cows (142±55 d in milk) were assigned randomly within ... Read more >>

Palmitic acid increased yields of milk and milk fat and nutrient digestibility across production level of lactating cows.

P Piantoni, A L Lock, M S Allen,

The effects of palmitic acid supplementation on feed intake, digestibility, and metabolic and production responses were evaluated in dairy cows with a wide range of milk production (34.5 to 66.2 kg/d) in a crossover design experiment with a covariate period. Thirty-two multiparous Holstein cows (151 ± 66 d in milk) ... Read more >>

Metabolic control of feed intake: implications for metabolic disease of fresh cows.

Michael S Allen, Paola Piantoni,

The objective of this article is to discuss metabolic control of feed intake in the peripartum period and its implications for metabolic disease of fresh cows. Understanding how feed intake is controlled during the transition from gestation to lactation is critical to both reduce risk and successfully treat many metabolic ... Read more >>

Level of nutrient intake affects mammary gland gene expression profiles in preweaned Holstein heifers.

P Piantoni, K M Daniels, R E Everts, S L Rodriguez-Zas, H A Lewin, W L Hurley, R M Akers, J J Loor,

Bovine mammary parenchyma (PAR) and fat pad (MFP) development are responsive to preweaning level of nutrient intake. We studied transcriptome alterations in PAR and MFP from Holstein heifer calves (n=6/treatment) fed different nutrient intakes from birth to ca. 65 d age. Conventional nutrient intake received 441 g of dry matter ... Read more >>

Expression of metabolic, tissue remodeling, oxidative stress, and inflammatory pathways in mammary tissue during involution in lactating dairy cows.

Paola Piantoni, Ping Wang, James K Drackley, Walter L Hurley, Juan J Loor,

Histological and functional changes associated with involution in the mammary gland are partly regulated by changes in gene expression. At 42 d postpartum, Holstein cows underwent a period of 5 d during which they were milked 1X daily until complete cessation of milking. Percutaneous mammary biopsies (n = 5/time point) ...

Functional and gene network analyses of transcriptional signatures characterizing pre-weaned bovine mammary parenchyma or fat pad uncovered novel inter-tissue signaling networks during development.

Paola Piantoni, Massimo Bionaz, Daniel E Graugnard, Kristy M Daniels, Robin E Everts, Sandra L Rodriguez-Zas, Harris A Lewin, Hurley L Hurley, Michael Akers, Juan J Loor,

<h4>Background</h4>The neonatal bovine mammary fat pad (MFP) surrounding the mammary parenchyma (PAR) is thought to exert proliferative effects on the PAR through secretion of local modulators of growth induced by systemic hormones. We used bioinformatics to characterize transcriptomics differences between PAR and MFP from approximately 65 d old Holstein heifers. ... Read more >>

Adipose tissue lipogenic gene networks due to lipid feeding and milk fat depression in lactating cows.

B J Thering, D E Graugnard, P Piantoni, J J Loor,

Dietary lipid supplements have been extensively evaluated for their effects on mammary tissue mRNA abundance, including the classical lipogenic genes ACACA, SCD, FASN, and the transcription regulators SREBF1, THRSP, and PPARG. Novel gene isoforms with key regulatory roles in triacylglycerol synthesis have been recently identified including LPIN1 and AGPAT6. Transcriptional ... Read more >>

Gene expression ratio stability evaluation in prepubertal bovine mammary tissue from calves fed different milk replacers reveals novel internal controls for quantitative polymerase chain reaction.

Paola Piantoni, Massimo Bionaz, Daniel E Graugnard, Kristy M Daniels, R Michael Akers, Juan J Loor,

Prepubertal mammary development can be affected by nutrition partly through alterations in gene network expression. Quantitative PCR (qPCR) remains the most accurate method to measure mRNA expression but is subject to analytical errors that introduce variation. Thus, qPCR data normalization through the use of internal control genes (ICG) is required. ... Read more >>
