EFFECT OF CHANGE OF CAGE AND/OR 44H MOTHER-LITTER SEPARATION ON PRODUCTIVITY OF NON-RECEPTIVE LACTATING RABBIT DOES. PRELIMINARY INVESTIGATION
2010
[EN] The effects of three different bio-stimulation methods, namely change of cage (CC), 44-hour mother-litter separation (MLS) and a combination of the two (CCMLS), for inducing oestrus in nonreceptive lactating does, were compared to the peñormance of receptive lactating does (RO). From March to July, 215 lactating does were taken to males for mating on day 9 after kindling. The 155 RO immediately mated. The does refusing to mate were divided in a balanced manner based body weight and parity and subjected to one of the three bio-stimulations. Receptivity in MLS does (72.7%) was higher than in ce (50.0%) and CCMLS groups (55.5%), and appeared more frequently (45.5%) on day 11, just after t…
Methicillin-resistant Staphylococcus pseudintermedius as causative agent of dairy cow mastitis.
2013
Staphylococcus pseudintermedius is a coagulase-positive specie similar to Staphylococcus intermedius , frequently associated with pyoderma, otitis and urinary tract infections of dogs and cats (van Duijkeren and others 2011). No information about bovine mastitis caused by S pseudintermedius is available in the literature. Antimicrobial resistance among S pseudintermedius strains is increasing: in the past, susceptibility to most antibiotics was common (Bond and Loeffler 2012), but in the last few years methicillin-resistant S pseudintermedius (MRSP) strains have emerged as a significant animal health problem in veterinary medicine (Schwarz and others 2008, van Duijkeren and others 2008, Wee…
Phenotypic and genotypic study on antibiotic resistance and pathogenic factors of Staphylococcus aureus isolates from small ruminant mastitis milk in…
2021
Staphyloccoccus aureus is the major cause of mastitis in small ruminants in the Mediterranean farms causing severe losses to dairy industry. Antibiotic treatment has been the most common approach to control these infections. Aim of this study was to investigate antimicrobial resistance (AMR), virulence factors and biofilm-related genes of 84 Sicilian strains of S. aureus isolated from sheep and goats milk during two different periods δT1 (2006-2009) and δT2 (2013-2015). Kirby Bauer method and Polymerase Chain Reaction (PCR) were utilized to monitor AMR and related genes (mecA, tetK, tetM, ermA, ermC). Moreover, toxin genes (tsst-1, sea-see, seg-sej, and sep) and biofilm genes (bap, ica, sas…
Genetic parameters for somatic cell score according to udder infection status in Valle del Belice dairy sheep and impact of imperfect diagnosis of in…
2010
Abstract Background Somatic cell score (SCS) has been promoted as a selection criterion to improve mastitis resistance. However, SCS from healthy and infected animals may be considered as separate traits. Moreover, imperfect sensitivity and specificity could influence animals' classification and impact on estimated variance components. This study was aimed at: (1) estimating the heritability of bacteria negative SCS, bacteria positive SCS, and infection status, (2) estimating phenotypic and genetic correlations between bacteria negative and bacteria positive SCS, and the genetic correlation between bacteria negative SCS and infection status, and (3) evaluating the impact of imperfect diagno…
Phenotypic and genetic analysis of udder health using SCC in Valle del Belice dairy sheep
2005
Intramammary infections (IMI) are a complex of inflammatory diseases which are defined as an inflammation of the mammary gland resulting from the introduction and multiplication of pathogenic micro-organisms.
Determination of milk production losses and variations of fat and protein percentages according to different levels of somatic cell count in Valle de…
2018
The somatic cell count (SCC) of milk is widely used to monitor udder health and the milk quality and because of its positive genetic correlation with mastitis this trait was included in breeding schemes of dairy sheep. The aim of this study was to estimate the loss in milk yield (MY) and related composition resulting from different levels of somatic cell count in Valle del Belice dairy sheep. Data were collected between 2006 and 2016 in 15 flocks following an A4 recording scheme. Somatic cell count (SCC), fat and protein percentage (F% and P%) were determined using mid-infrared spectroscopy. To evaluate loss in test day MY, F% and P%, five different classes of SCC were arbitrarily defined: …
Coincidence of nonpuerperal mastitis and noninflammatory breast cancer.
2002
Abstract Background : Nonpuerperal mastitis may mimic breast cancer but the incidence of noninflammatory cancer among such patients is unknown. Aim : To estimate the risk of breast cancer in patients with nonpuerperal mastitis within 12 months of treatment. Study design : Two hundred seventy-seven patients with nonpuerperal breast inflammation were prospectively screened for breast cancer within 1 year after mastitis was diagnosed. The age-related standardized breast cancer incidence ratio of the female population was calculated. Results : Five women (35, 43, 47, 61, and 72 years, respectively) were identified as having noninflammatory breast cancer independently, and at a location distant …
Effect of somatic cell count level on functional longevity in Valle del Belice dairy sheep assessed using survival analysis.
2009
The objectives of this study were to evaluate the effect of somatic cell count (SCC) on functional longevity and to estimate the heritability of functional longevity using survival analysis in Valle del Belice dairy sheep. A total of 4,880 lactations of 2,190 ewes from 11 flocks were used. In this study, SCC was considered as an indication of subclinical mastitis. In case of clinical cases, identified by the technicians at milking time, test-day weights and milk samples of those ewes were not considered. Somatic cells were analyzed as counts, without any transformation, and were grouped in 3 classes based on the observed SCC maximum (mxSCC). The mxSCC classes, expressed as 103 cells/mL, wer…
Effect of weather conditions on somatic cell score in Sicilian Valle del Belice ewes
2010
Mastitis susceptibility of Valle del Belice ewes from the south of Sicily to temperature, humidity, precipitation, solar radiation, sun hours, air pressure, wind-speed and wind-direction measured by a public weather station was investigated using 65,848 test-day somatic cell score (SCS) records of 5,237 ewes. All weather parameters had an effect on SCS in a regression approach. Extreme values of maximum and minimum temperaturehumidity indices resulted in increased SCS. Higher precipitation, solar radiation and sun hours resulted in increased SCS, whereas higher air pressure and wind speed resulted in reduced SCS.
