Inducing a transient state of hypocalcemia prepartum mobilizes stored calcium (Ca) before the abrupt demand for Ca at parturition thus more tightly regulating postpartum hypocalcemia. Prepartum can be achieved through intravenous infusions either precursor to serotonin, 5-hydroxy-tryptophan (5HTP) or chelating agent, ethylene-glycol-tetraacetic acid (EGTA). This study aimed compare ability 5HTP and EGTA treatments prevent We hypothesized that 2 methods would similarly effective compared with...
Milk yield (MY) naturally declines after peak lactation. One approach to improving production is increase lactation persistency, or the length of time a cow maintains To do so, cows must maintain functional secretory mammary epithelial cells (MEC), which synthesize milk. Some viable MEC are exfoliated from udder into The objective this experiment was identify magnitude and direction association between MY, days in milk (DIM), parity. Our hypothesis that MY quantity were negatively...
This study aimed to characterize the effects of increased milking frequency (IMF) at early and mid-lactation on milk yield its association with changes in cistern alveolar capacity. Fourteen multiparous Holstein cows were subjected IMF using unilateral frequent method from 3 24 d (DIM). At mid-lactation, randomly assigned 1 2 treatments: control or repeated. From 150 170 DIM, treatment was reimposed repeated group. During IMF, left udder halves milked 2× right 4× daily. To separate...
Dairy farm profitability depends on milk yield, so the dairy industry manages cows to improve their productivity. Both bovine somatotropin (bST) and early lactation increased milking frequency (IMF) yield (MY) in cows. The objective of this study was evaluate effects mid-lactation bST administration production established when combined with carry-over effect from IMF. Thirteen multiparous Holstein were milked unilaterally for 20 days lactation. left udder halves twice daily (2X) right four...
Abstract Background and Aims The objective of this case report was to describe an ultrasound‐guided, minimally invasive method for longitudinal mammary gland tissue collection from the bovine species. Materials Methods Biopsies were performed on 14 8‐week‐old calves 113 10‐week‐old calves. A subset 36 animals had repeated biopsies through first lactation. Mammary using a disposable biopsy punch. technique also multiparous cows other independent research trials. Results One‐hundred thirteen...
