The antioxidant haptoglobin (Hp) is an acute-phase protein responsive to infectious and inflammatory diseases. Hp and somatic cell counts (SCC) are sharply elevated in bovine milk following intramammary administration of endotoxin or bacteria. However, the sources of milk Hp responsible for such increases are not fully understood. The purpose of this study was to define the source of milk Hp fr...

To analyze the effects of some environmental factors such as herd, year, season of calving, stage of lactation on mastitis incidence, a total of 101147 monthly test day somatic cell counts collected from 13977 Iranian Holstein heifers calved between 2002 and 2006 in 183 herds were used. The event of mastitis in cows was coded as 1 if their somatic cell count at specific test day was greater tha...

This study aims to investigate the effectiveness of teat dipping using sirih leaf extract (Piper betle) and bacteria in dairy farms located Cijeruk Subdistrict, Bogor Regency, West Java. The research employs an experimental design utilizing a Completely Randomized Design (CRD) with four treatments: (1) masofilm (2% iodine) as positive control, (2) bacteriocin (protein content = 11.17 g mL-1) (P...

The aim of this experiment was to study the effect betel leaf meal (BLM) as feed additive on milk composition and somatic cell count subclinical mastitis infected cow. design a completely randomized with five dietary treatments BLM level four replications in concentrate feed. were T0 (without meal, control), T1 (2% every day), T2 (4% T3 skip two days), T4 days). Milk samples from quarter would ...

This study aimed to analyze the principal components of meteorological variables, physiological and behavioral response cows subjected different cooling times their influence on milk quality, in dry rainfall periods, establish multiple regression models for quality. The data used came from an experiment conducted Agreste Region Pernambuco. pre-milking time was 10, 20, 30 min. control (without c...

milk is often described as a complete food because it contains protein, sugar, fat, vitamins, and minerals. this study was performed to investigate risk factors affecting chemical and bacteriological quality of bulk tank milk. according to the following conducted experiments, the milk was divided into two standard and non-standard groups. then, effect of risk factors on making the samples non-s...

Economic values of milk volume (VOL), fat yield (FYLD), protein yield (PYLD), live weight (LWT), longevity (LON), calving interval (CIV) and somatic cell score (SCS) were derived for Holstein and Jersey cattle, based on milk payment systems of four major milk buyers in South Africa. The economic value of somatic cell score was calculated for only two of the payment systems. A bio-economic model...

The aim of this study was to investigate total antioxidant (TAC), and oxidant capacity (TOC) and nitric oxide (NO) levels in milk of cows with subclinical mastitis. Brown Swiss and Holstein breed cows were screened with California Mastitis Test (CMT) to determine mammary glands with subclinical mastitis. Moreover, somatic cell counts (SCC) were determined electronically in all milk samples. Mam...

A total of 1014 samples taken from Lithuanian cows at the end of milking were tested on several parameters: milk reaction with Mastest (developed, tested, and produced at the Lithuanian Veterinary Institute), California Mastitis Test (CMT), Bernburg, Profilac reagent, Eimü-milchtest. Somatic cell count (SCC) was established using the flow cytometry method and Anadis F device; electrical conduct...

Bulk milk somatic cell count (BMSCC), individual cow somatic cell count (ICSCC), and incidence rate of clinical mastitis (IRCM) are all udder health parameters. So far, no studies have been reported on the effect of season on BMSCC, IRCM, and ICSCC in the same herds and period over multiple years. The objectives of this study were to determine the seasonal pattern over a 4-yr period of 1) BMSCC...
