Süt insanların günlük beslenmesinde vazgeçilmez bir besin konumundadır, özellikle sağlıklı süt tüketimi için kaliteli ve güvenli üretim vazgeçilmez bir unsurdur. Süt üretiminde hayvanların sağlık ve genotipik özellikleri üretimi doğrudan etkilemektedir. Kaliteli bir üretim doğru hayvan bakım programı ve hijyenik koşullara uyulmasıyla mümkün olabilmektedir. Bu kapsamda çalışmada Kütahya’nın Altıntaş ve Uşak’ın Banaz ilçelerindeki hayvanların meme sağlığının ve süt bileşiminin belirlenmesi amaçlanmıştır. Altıntaş’ta 3 köydeki 77 inekten, Banaz’da 2 köydeki 49 inekten süt örnekleri toplanmıştır. Sütün bileşimi yağ (%), kurumadde (%), yoğunluk (%), protein (%), laktoz (%), tuz (%), donma noktası (°C), iletkenlik (ms/cm) yönünden karşılaştırılmış ve mastitis prevalansı Californian Mastitis Testi (CMT) ile araştırılmıştır. Elde edilen verilere göre işletmelerin büyük bir çoğunluğunda mastitis varlığına rastlanmazken, mastitis belirtileri görülen ineklerin genellikle aynı işletmede yetiştirilen inekler olduğu belirlenmiştir. İlçeler arasında Altıntaş ilçesindeki ineklerin yağ oranı daha düşük (%3,51), kuru madde oranı (%9,26) ve protein oranının da daha yüksek (%3,33) olduğu belirlenmiştir. Banaz ilçesinde de sütlerde laktoz oranları (%4,78) daha düşük, yoğunluk (% 28,08) daha düşük, iletkenliğinin de daha yüksek (4,95 ms/cm) olduğu tespit edilmiştir. Köyler arasında süt kalitesi yönünden en yüksek değerlere Çayırbaşı köyünde yetiştirilen inekler olduğu belirlenmiştir. Bunda üreticilerin bilinç düzeyinin yüksek olmasının, sözleşmeli üretim yapılmasının ve hijyen koşullarına dikkat edilmesinin sonucunda olduğu düşünülmektedir.

In every year, Subclinical mastitis (SCM) frequently occurs and results huge economic losses in livestock industry of Bangladesh. This study was redacted to estimate the present status of SCM in cow in selective area of Barisal district. For determining sub-clinical mastitis, a total of 152 milk samples of clinically suspected cows were subjected to White Side Test (WST) and Surf Field Mastitis Test (SFMT). Specifically, the milk samples of each individual cows which were positive to both WST and SFMT considered as SCM indicating 35.52% prevalence. Other than the local breed cows, the cross bred cows showed significantly higher prevalence, is 47.06%. In consideration to age variation, highest prevalence was observed at 5 to 7 years of age in both types where cross breed was 54.71% and 36.67% for local breed cows. Though highest prevalence was recorded as 34.78% in 2nd parity of local breed cows but the cross breed cows showed highest prevalence 54.55% in their 3rd parity. Afterward, non-pregnant cows showed the insignificantly higher prevalence (41.06%) than pregnant cows were 26.32%. Additionally, this study reported that the cross breed cows yielding more than 10 liters of milk (prevalence was 61.54%) were more prone to SCM than the others and also >5 to 10 liters milk producing local breed cows (prevalence was 31.03%) were more susceptible to SCM than others. In a short, this study revealed that high milk yielding cross breed cows are more likely to SCM after their 3rd calving.

Antibiotic resistance is being constantly developed worldwide. Coagulase Negative Staphylococci (CNS) and Staphylococcus aureus are common causes of bovine subclinical mastitis. Bioactive compound of medicinal plants shows anti-microbial, anti-mutagenic and anti-oxidant effects. The anti-bacterial and anti-oxidant activities of Liquidambar orientalis (L. orientalis) extracts on subclinical mastitis causing bacteria in cows have not been reported to date. The aim of the present study was to examine anti-bacterial and anti-oxidant effects of L. orientalis leaf extracts on S. aureus and CNS isolated from cows with subclinical mastitis symptoms. In this study, 3.2 mg/mL minimum inhibitory concentration (MIC) of ethanol extracts of L. orientalis has shown to be a most potent anti-bacterial and anti-oxidant for all isolated bacterial species from mastitis cows. In this study, it was investigated anti-bacterial and anti-oxidant potentials of acetone, methanol and ethanol extracts of the L. orientalis. The acetone extract showed maximum inhibition zone against S. aureus numbered 17 (12 mm). In addition to anti-bacterial properties, anti-oxidant activity of L. orientalis extract was examined by ABTS [2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)] free radical assay. Trolox was used as a positive control anti-oxidant. Ethanol extract exhibited a strong anti-oxidant activity like Trolox anti-oxidant which was effective at 2.58 mM concentration. Bioactive compounds of sweet gum may be useful to screening mastitis causing bacteria for clinical applications.

Bovine and caprine mastitis is a dreadful bacterial disease that drastically lowers milk production, and presently it is spreading as an endemic pathogen throughout the world, including Bangladesh. Moreover, mastitis is the main impediment to Bangladesh’s tremendously rising milk-related industry and general livestock economy. Therefore, the aim of this study is to demonstrate the overall prevalence of clinical and sub-clinical mastitis in both dairy cows and goats. It is the foremost meta-analysis study regarding mastitis prevalence in Bangladesh and the study gathered the articles from the electronic database on the topic bovine and caprine mastitis published between January 2005 and November 2020. Finally, 33 articles were selected for estimating the overall prevalence rate of mastitis in ruminant (cow and goat) via random effect model estimation. Analyzing the result, the study found 43.0% (95% Cl: 37.0 - 50.0%) and 31.0% (95% Cl: 15.0 - 47.0%) prevalence rate in dairy cattle and goat. Statistically, the occurrence rate in Bangladesh is significantly higher than other countries. Although many studies showed the seroprevalence across different districts, this study demonstrates the aggregate incidence rates across Bangladesh as a whole. This paper may also serve as a reference point for the implementation of any control strategy of mastitis in Bangladesh.

Mastitis is an economically important disease of intensive buffalo dairy farming worldwide. Detection of subclinical mastitis (SCM) is important for its management and control. The purpose of this study was to estimate the prevalence of reproductive disorders, SCM and udder health management practices in the buffalo dairy farms of Bhola District, Bangladesh. Data on animal demographics, reproduction status, daily milk yield and status of California Mastitis Test (CMT) result were recorded. A total of 402 buffaloes were observed in two farms at Bhola district and among them 70 milking buffaloes were randomly selected for CMT. The overall prevalence of SCM in buffalo was 20.0%. Young age group of buffaloes was more susceptible for SCM and it was not significant difference. Parity and stage of lactation have no any effect on SCM. However, abortion case was more susceptible to SCM than other diseases but not any significant difference. During milking the milkers never use any antiseptic solution for washing the udder and never use any feed supply during milking. Among the isolated organisms Staphylococcus spp. and E. coli were found more frequent in the study area and gentamicin and ciprofloxaclin were most sensitive to the isolated organisms. From this study it was concluded that buffalo’s udder was very resistance to SCM infection and udder management practice was very poor. Common antibiotics were resistance to isolated organisms from SCM case. Gentamicin and ciprofloxacin were found more susceptible against all four isolated organisms.

The aim of this study was to determine the factors affecting mastitis cases and to estimate the correlations of somatic cell count (SCC) with milk yield in Holstein cows. The study was conducted in two private dairy farms in Hódmezõvásárhely, South-Hungary. A total of 882 Holstein cows were tested by SCC, fat and protein contents of milk monthly intervals. To test milk SCC and components, two groups were designed, and to examine effect of parity on first mastitis day (FMD) and total mastitis cases (TMC), four groups were divided. It was noted that higher SCC caused to higher TMC. While cows had higher protein content exposed to higher FMD and TMC, cows had lower daily milk yield (DMY) had higher values by mastitis case parameters. In parity evaluation, only primiparous cows had statistically lower TMC. The cows with lower SCC were found in advance in change of milk yield (CMY) up to 6.858±0.947 kg. A negative correlation coefficient was estimated between SCC and DMY. Finally, monitoring SCC of milk is offered to prevent milk production losses and new mastitis occurrences in the herds.
