“…In this study, we found 27.7% (46/166) of CNS isolates, and differing from studies performed in other regions of Brazil, where they found CNS in 83.3% (Neves et al 2010) and 79.7% of isolates in the Northeast region (Cavalcante et al 2013), and 62.2% ) and 90.5% (Gomes et al 2014) in the Southeast region. In Brazil, only phenotypic methods have been used in the identification of bacterial species from caprine mastitis samples in the studies published so far.…”

“…The risk factors found for mastitis in this study differed from those found in the few similar studies done in Brazil (Neves et al 2010, Gomes et al 2014). These studies relate to risk factors for caprine mastitis in the northeast region of the country, where the breeds, management and climatic conditions are different.…”

“…The prevalence of subclinical mastitis found in this study was 28%, in agreement with other study conducted in Brazil, the Southeast region by Gomes et al (2014) and the northeastern region by Bianchini et al (2010) and Peixoto et al (2012). In Italy, Dore et al (2016) also found the similar prevalence.…”

Mastitis in dairy goats from the state of Minas Gerais, Brazil: profiles of farms, risk factors and characterization of bactéria

et al. 2018

The Zona da Mata of Minas Gerais has a specialized goat milk production chain. Goat milk is superior in quality compared with milk of other domestic species, and the demand for milk and milk products for the public has increased. Data on dairy goat breeding in Minas Gerais are scarce and relatively old, and this lack of information has limited the implementation of prophylactic measures, especially for mastitis, which represents the biggest sanitary problem for dairy herds. The objective of this work was to characterize mastitis and bacteria associated with it in milking goats in the Zona da Mata of Minas Gerais. It also causes socioeconomic problems and market issues for dairy goat farming. A total of 539 lactating goats were examined and 268 individual samples (one for teat) were collected from animals positive for strip cup test and/or the California Mastitis Test (CMT). Microbiological cultures were carried out on blood agar medium and the bacteria were subjected to phenotypic, genotypic and antimicrobial susceptibility tests. The prevalence of subclinical mastitis was 28.0% and the clinical prevalence was 2.8%. Bacterial multiplication was obtained in 62% of samples. One hundred eighty seven total bacteria were identified. The most common species identified was Staphylococcus aureus (60%), followed Staphylococcus epidermidis (9.1%,), Escherichia coli (6.9%), Staphylococcus saprophyticus (5.9%) e Staphylococcus caprae (4.3%). Bacteria of the genus Staphylococcus presented a profile of resistance to antimicrobials belonging to the beta-lactam class (penicillin, ampicillin and oxacillin) in addition to tetracycline, in contrast to the other antimicrobials tested. Twelve percent of multidrug resistence (MDR) was found in five microregions. Among the bacteria with the highest prevalence of MDR, 38.5% were E. coli and 10.6% were S. aureus. The producers of the Zona da Mata of Minas Gerais are technicians who work with specialized dairy breeds and practise good management. However, some measures related to prophylaxis and control of diseases, such as vaccination, have low adherence or are not performed due to a lack of veterinary assistance. This is the first study focusing on this region, which is highly prominent in goat milk production in Brazil. It provides important information that can help in the implementation of measures for the prophylaxis and control of diseases, and for maintenance of a constant supply of products in sufficient quantities and of a quality suitable for the consumer population.

“…The identification of the non-aureus Staphylococci group was performed by the macroscopic and microscopic evaluation of the colonies, catalase and coagulase tests; RapID identification systems (Remel-Oxoid) were also used for Staphylococcus aureus; and the catalase test and macro and microscopic identification of the colonies were performed for Corynebacterium spp. (GOMES et al, 2014). The results obtained for the microbiological examination were distributed in score 0 (negative) and score 1 (positive).…”

“…Excessive vacuum, failure or absence on the pulse, inappropriate pulsation rate and intervals between milking shorter than 10 h increase the intensity of tissue damage and reduce the strength of the teat channel by compromising the physical defense mechanism (LU et al, 1991;ALEJANDRO et al, 2014a). In addition, the lack of hygiene in the milking process represents a risk factor for caprine mastitis (WÓJTOWSKI et al, 2006;GOMES et al, 2014).…”

This research evaluated the effect of milking on the physical exam of the mammary gland (MG) and milk examination in Saanen goats. Six properties were selected, four farms were used after evaluation of criteria selection and distributed in two groups according to the milking method: manual or mechanical. The physical examination of MG was performed using the techniques of inspection and palpation, in addition to the examination of the milk by strip cup, California Mastitis Test, somatic cell count, and bacteriological exam. It was possible to detect an association between the milking method with the most of physical exam of the MG: inspection of the MG (p = 0.001), inspection of the teat (p = 0.002), palpation of the MG (p = 0.054) and palpation of the teat (p = 0.036). The machine milking had an association with the reduction of the volume of MG (OR = 6.00), reduction of the teat size (OR = 16.19), and firm consistency of mammary parenchyma (OR = 2.39). The use of machine milking represented a less risk for an increase of the volume of the MG volume (OR = 0.288) and the presence of cisternitis (OR = 0.490). The association between the SCC and the type of milking was also detected (p = 0.002). Machine milking was associated with changesin the physical exam of MG and milk examination compatible with traumatic lesions. This information indicates inappropriate use of milking equipment in the dairy goat’s properties.

Analysis of Management, Labor and Economics of Milking Systems in Intensive Goat Farms

2022

Dairy goat farms are growing in the world, but their technological level and, particularly, milking equipment are less developed than those of dairy cow farms. This study aims to evaluate milking parlors in the current situation in modern goat farms and suggest possible solutions or improvements. Ten goat farms located in various municipalities of the Friuli-Venezia Giulia region (Northeast Italy) adopting different milking systems (parallel milking parlors, milking carts, and milking buckets) were monitored. The mathematical model developed originally for the evaluation of milking parlors for dairy cows was modified and adapted to goat milking systems. Time for milking and final specific direct costs are the main parameters that enable evaluation and choice of suitable milking parlor; neglect or promotion of only one of the mentioned criteria may lead to an uneconomic investment or impaired operation of a farm. The research results showed that the modern milking systems, with a greater number of stalls and milking clusters, have a greater capacity and require less time for milking a goat than bucket and cart systems. The study also demonstrated that increasing the capacity of dairy goat farms enables a reduction of the final specific costs for milking.
