“…In a study conducted in goats (19), PI and SPV were increased in animals with clinical mastitis, resulting from an increase in blood flow due to infection-related inflammation. In the present study, PI and SPV were found to be higher in CMT-positive animals, although the difference was statistically insignificant.…”

“…Berger et al reported that pulsed wave Doppler ultrasonography can be used to analyze blood flow to udder, sharing the finding that ultrasonographic parameters regarding blood flow to udder increased with milk yield (1). Pulsed wave Doppler ultrasonography is used to measur values such as Time-Averaged Maximum Velocity (TAMV), blood flow volume, Systolic Peak Velocity (SPV) and Resistant Index (RI) in vessels supplying blood to udders (10,17,18,19).…”

Summary:This study aimed to determine the distribution of pulsed wave Doppler ultrasonographic features of milk veins in lactating cows corresponding to udder health and the results of California Mastitis Test (CMT). Clinically healthy Simmental cows aged 3-5 years within the first 12 weeks of postpartum period were used for the study. End Diastolic Velocities (EDV), Systolic Peak Velocity (SPV), and Time-Averaged Maximum Velocity (TAMV) were the measured Doppler features of the milk veins. Numerical scales for Pulsatile Index (PI) and Resistant Index (RI) were devised in accordance with blood flow parameters. The animals were allocated to two groups according to CMT results as CMT positive (n=21) and CMT negative (n=5). No differences were found between the group regarding to PI, RI, EDV, or SPV (p>0.05). However, TAMV was found to be lower in CMT-positive animals (7.52 ± 0.85 cm/sec) compared to CMT-negative (13.90 ± 3.56 cm/sec) animals (p=0.021).

“…Regarding mastitis, many studies have employed the Doppler ultrasonographic examination for the investigation of the infection in cattle [ 53 ], buffaloes [ 54 ], and sheep [ 50 ], thus nowadays the Doppler examination is considered a precise method for the diagnosis of this disease. Santos et al [ 55 ] have indicated that increased PSV and RI in cases of mastitis in goats are probably related to more severe infections. Furthermore, the examination of the supramammary lymph nodes may also provide useful information regarding infection in cows [ 42 ].…”

The study of the structure and function of the animals’ mammary glands is of key importance, as it reveals pathological processes at their onset, thus contributing to their immediate treatment. The most frequently studied mammary diseases are mastitis in cows and ewes and mammary tumours in dogs and cats. Various imaging techniques such as computed tomography, positron emission tomography, magnetic resonance imaging, and ultrasonographic techniques (Doppler, contrast-enchanced, three-dimensional and elastography) are available and can be applied in research or clinical practice in order to evaluate possible abnormalities in mammary glands, as well as to assist in the differential diagnosis. In this review, the above imaging technologies are described, and the perspectives of each method are highlighted. It is inferred that ultrasonographic modalities are the most frequently used imaging techniques for the diagnosis of clinical or subclinical mastitis and treatment guidance on a farm. In companion animals, a combination of imaging techniques should be applied for a more accurate diagnosis of mammary tumours. In any case, the confirmation of the diagnosis is provided by laboratory techniques.

“…This technique allows non-invasive investigation of the cistern and could be useful as a new approach to study udder changes to accommodate milk accumulation during different milking intervals and after milk letdown (Salama et al, 2004). Ultrasonography has been used as a non-invasive method to study the internal structure of the mammary gland in dairy goats (Melo et al, 2012;Díaz et al, 2013;Alejandro et al, 2014;Dar et al, 2014;Fasulkov et al, 2014a,b;Santos et al, 2014Santos et al, , 2015, and cows (Bruckmaier et al, 1994;Ayadi et al, 2003;Bobić et al, 2014;Esselburn et al, 2015;Khoramian et al, 2015) in order to measure the milk storage capacity within the udder. The aim of the present study was to estimate genetic parameters underlying selected udder measurements as detected by ultrasonography.…”

La taille de la citerne de lait a été diagnostiquée chez les brebis en utilisant l’échographie et la sonde linéaire de 3,5 MHz de deux façons: La méthode de côté et celle de bas. L’échographie a été faite à partir de chaque scan et ensuite la taille du réservoir à gauche et à droite a été mesurée en utilisant la technique numérique. Les deux citernes ont été scannées environ 12 heures après la dernière traite. L’espace gauche de la citerne (ALC1; 1.933.35 mm2) et celui de droite (ARC1; 1.970.72 mm2), détectés par la méthode de côté, ont été diagnostiqués à plusieurs reprises chez 378 brebis (pendant l’allaitement ainsi qu’entre lactations); un total de 1198 mesures ont été effectuées. L’espace gauche de la citerne (ALC2; 2.137.67 mm2) et de droite (ARC2; 2.171.12 mm2), détectés par la méthode du bas, ont également été diagnostiqués à plusieurs reprises, notamment chez 265 brebis; 753 mesures ont été réalisées au total. La somme des deux zones de section transversale détectées par la méthode de côté (SLRC1) était de 3904.07 mm2, et celle détectée par la méthode de fond (SLRC2) était 4308.77 mm2. Les données primaires ont été traitées en utilisant la méthodologie REML et le modèle animal trait multiple, en utilisant des programmes comme REMLF90 et VCE 4.0. En plus de l’effet génétique additif aléatoire des animaux et l’effet permanent des brebis, les modèles incluent l’année de contrôle comme facteur fixe (7 ou 5 niveaux), un stade de lactation (4 niveaux), un groupe de race (9 niveaux) et la parité (3 niveaux). Nous avons trouvé des valeurs plus élevées de h2 pour les paramètres diagnostiqués par la méthode du bas. Le coefficient d’héritabilité pour ALC1 et ALC2 était de 0.07 et 0.18, respectivement; pour ARC1 et ARC2 de 0.17 et 0.2, resp.; et pour SLRC1 et SLRC2 de 0.12 et 0.17, respectivement. Les corrélations génétiques entre ARC1 et ARC1 ou ARC2 et ARC2 étaient élevées (rg= 0.73 ou 0.910). De même, les corrélations entre la taille de la citerne gauche et/ou droite, et la taille totale des deux citernes étaient élevées avec les deux modes de scan (rg= 0.90 à 0.98). En conclusion, la mesure de la taille des citernes de lait par la méthode de côté est plus recommandée, bien que les mesures avec la méthode du bas montrent des coefficients d’héritabilité légèrement plus élevés.
