Jugular versus Mammary Vein Acid-Base Balance, Blood Gases, Hematobiochemical Profiles and Inflammation Biomarkers in Goats with Acute Mastitis
The objectives of this study was to investigate the acid-base balance, blood gases, hematobiochemical profiles and the inflammation biomarkers fibrinogen, serum amyloid A (SAA) and haptoglobin (Hp) in the mammary and jugular veins of goats with mastitis. Blood samples were collected from the jugular and mammary veins from 26 goats with mastitis and from 10 healthy lactating goats. In diseased goats, the affected quarter had a remarkable degree of swelling, hard and sore to touch; the milk was bloody. In the jugular vein of diseased goats, the values of PCO2, PO2, base excess (BE), HCO3 and TCO2 were significantly lower than in the jugular vein of controls.
Shipment of liquid milk samples for bacteriological examination is a limitation to large scale epidemiological studies. Sampling bulk tank milk (BTM) with sample collection cards (WhatmanTM FTATMMiniCard) was identified as an interesting procedure to ease sample collection and shipment.
Outcome Following Surgical Correction of Abomasal Displacement in Lactating Dairy Cattle: A Retrospective Study of 127 Cases (1999-2010)
The objectives of this retrospective study were 1. To determine the effect of three surgical techniques (right flank omentopexy, right flank omentoabomasopexy, and left flank abomasopexy), and 2. To determine the effect of concurrent disease on return to normal milk production. Return to normal milk production occurred in 86.3% of cows diagnosed with LDA. Results suggested that cattle diagnosed with LDA corrected via right flank omentopexy or left flank abomasopexy were significantly more likely to return to normal milk production as compared to those corrected via right flank omentoabomasopexy (p<0.02). No significant difference in return to normal milk production was noted between surgical techniques for correction of RDA (p=1.000) and right abomasal volvulus (p=0.596). Concurrent disease diagnoses did not affect return to milk production. Reported complications were infrequent (n=11).
The discovery of the presence of stem cells and precursors with high regenerative potential in the mammary gland, hypothetically maintained throughout the course of the productive life of the dairy cow sheds an interesting perspective in the research which is interested to clarify all physiological clues and possible solutions to increase or maintain longer the potential production of dairy cows during life span of lactation.
