Purpose: At present, in Lankapura, there is a tremendous development in dairy sector. But milk quality issues were raised by the milk consumers and producers who collected milk from Lankapura. Although, measures have been taken to increase the milk production, the quality of milk has not been thoroughly evaluated in area. Research methodology: This study was carried out to evaluate the microbiological, compositional quality of cow’s milk collected from small scale farmers (25) and bulk milk tanks (25 samples) in the study area and to collect data about knowledge of farmers on clean milk production practices. Findings: According to the study, acidity, and average level of bacterial count of household milk production were 0.229±0.029%, 6.193±0.311 log10 CFU/ml respectively and for bulk milk production were 0.294± 0.020%, 6.6427±0.322 log10 CFU/ml respectively. The mean percentage of specific gravity, protein, fat, lactose and SNF for bulk milk samples were 1.029g/ml, 2.740%±0.0866, 4.120%±0.8065, 4.040%±0.1581, 7.6476%±0.34219 respectively and for household’s milk samples were 1.028g/ml, 2.792% ±0.1706, 4.360%±0.7314, 4.032%±0.1973, 7.5716%±0.33726 respectively. When considering management practices of farmers, only 38% farmers cleaned the milking place. Only 28% of farmers maintained proper records. The results indicated that microbiological and compositional quality (except milk fat) were not in acceptable level for both household and bulk milk samples. For microbiological quality, there was a high statistical significance of bulk milk samples than the households. Limitations: The quality of the milk was poor due to unhygienic practices and poor knowledge. Sample numbers were limited in this study, due to limited time period for this study. Larger individual coliform count could not be conducted due to limited manpower and laboratory resources. Originality/ value: As long term solutions such as farmer education programmes, incentive based milk quality systems can be recommended.

Hypoglycin A (HGA) originating from soapberry fruits (litchi, and ackee) seeds or seedlings from the sycamore maple (SM) tree (related to Sapindaceae) may cause Jamaican vomiting sickness in humans and atypical myopathy in horses and ruminants. A possible transfer into dairy cow’s milk cannot be ruled out since the literature has revealed HGA in the milk of mares and in the offal of captured deer following HGA intoxication. From a study, carried out for another purpose, bulk raw milk samples from four randomly selected dairy farms were available. The cows were pastured in the daytime. A sycamore maple tree was found on the pasture of farm No. 1 only. Bulk milk from the individual tank or milk filling station was sampled in parallels and analyzed for HGA by LC-ESI-MS/MS. Measurable concentrations of HGA occurred only in milk from farm No. 1 and amounted to 120 and 489 nmol/L. Despite low and very variable HGA concentrations, the results indicate that the ingested toxin, once eaten, is transferred into the milk. However, it is unknown how much HGA the individual cow ingested during grazing and what amount was transferred into the bulk milk samples. As a prerequisite for a possible future safety assessment, carry-over studies are needed. Furthermore, the toxins’ stability during milk processing should also be investigated as well.

The subject of this research is cattle breeding with a focus on the production of cow's milk in the Republic of Serbia. The main goal is to analyze the state and trends of cow's milk production in Serbia during the last ten years in relation to production in Europe, the European Union and the world. Data from the SORS, FAO databases, etc. were used. In Serbia, 908,102 head of cattle are raised on 177,552 family farms, ie, an average of 5.11 head of cattle per farm. The number of cattle has dropped by more than 200,000 head over the last decade. In the total milk production in Serbia, cow's milk accounts for 96.84%. The average milk yield of cows in Serbia is far below the European average. The highest average amount of milk is recorded in the Belgrade region, where 5,335 liters per milking head are produced in one year. The quality of cow's milk in Serbia is far below EU standards, which is a key restriction on exports.

1. The results of a survey of the methods of milk production on a random sample of farms in four counties of England and Wales were used in conjunction with bacteriological and keeping quality tests of the milk produced, to estimate the influence on milk quality of factors in equipment and technique.2. Of the many factors in technique investigated, only the sterilization of utensils and the cooling of the milk appeared to affect milk quality. The effects of these two factors differed in some degree with the four tests used.3. Milk samples from machine-milked herds had significantly greater thermoduric colony counts than samples from hand-milked herds. No other factor of equipment showed appreciable association with milk-quality tests.4. Brief recommendations are made about the conduct of any future field survey of factors affecting bacteriological and keeping quality of milk.

Parenica is a steamed, lightly smoked or unsmoked cheese wounded into a roll made from pasteurized cow's milk, with characteristic pronounced fibrous structure of curd. The aim of this work was to set up the sensory profile of smoked and unsmoked parenica cheese varieties made from pasteurized cow's milk and changes in sensory descriptors during 14 days of storage period at the temperature of 4 ±2 °C. Descriptive analysis was carried out by 18 trained assessors, who used a vocabulary of 26 terms to quantitatively describe appearance, aroma, consistency and taste of the experimental samples and also these overall sensory parameters with acceptability. Assessors evaluated the intensity of each descriptor by assigning the score on a 10 points linear scale. Analysis of variance found significant differences between cheese varieties (p <0.05) and the effect of storage period (p <0.05) on sensory quality of experimental parenica cheese varieties. The analysis showed that each sample group in observed representative sensory attributes was significantly different (p <0.05). Multiple factorial analysis showed in parenica cheese samples three selected components that explain more than 69% of the total variation in the dataset at the level of statistical significance p <0.05.

Our aim is to assess the efficacy of fecal calprotectin (fCP) and fecal eosinophil-derived neurotoxin (fEDN) as diagnostic markers of cow’s milk protein allergy (CMPA) and for monitoring the infants’ response to a non-IgE mediated cow’s milk protein (CMP)-free diet. We prospectively recruited infants aged 0 to 9 months. Stool samples were taken from 30 infants with CMPA, 19 with mild functional gastrointestinal disorders, 28 healthy infants, and 28 children who presented mild infections. Despite the fact that levels of fCP and fEDN in CMPA infants were higher than in healthy infants at month 0, differences for both parameters did not reach statistical significance (p-value 0.119 and 0.506). After 1 month of an elimination diet, no statistically significant differences in fCP with basal levels were found (p-values 0.184) in the CMPA group. We found a high variability in the fCP and fEDN levels of young infants, and discrepancies in individual behavior of these markers after a CMP-free diet was started. It seems that neither fCP nor fEDN levels are helpful to discriminate between healthy infants and those with signs or symptoms related to non-IgE-mediated CMPA. Additionally, it is debatable if on an individual basis, fCP or fEDN levels could be used for clinical follow-up and dietary compliance monitoring. However, prospective studies with larger populations are needed to draw robust conclusions.

Previous studies have suggested that an unidentified cow's milk protein, other than β-lactoglobulin and casein, might play a pathogenetic role in infant colic. Therefore, a radioimmunoassay was used to analyze human breast milk and infant formula samples for the presence of bovine IgG. Milk samples from 88 of the 97 mothers tested contained greater than 0.1 µg/mL of bovine IgG. In a study group of 59 mothers with infants in the colic-prone 2- to 17-week age group, the 29 mothers of colicky infants had higher levels of bovine IgG in their breast milk (median 0.42 µg/mL) than the 30 mothers of noncolicky infants (median 0.32 µg/mL) (P &lt; .02). The highest concentrations of bovine IgG observed in human milk were 8.5 and 8.2 µg/mL. Most cow's milk-based infant formulas contained 0.6 to 6.4 µg/mL of bovine IgG, a concentration comparable with levels found in many human milk samples. The results suggest that appreciable quantities of bovine IgG are commonly present in human milk, that significantly higher levels are present in milk from mothers of colicky infants, and that bovine IgG may possibly be involved in the pathogenesis of infant colic.

In this paper, influence of the composition of autohtonous Sjenica cheese and composition of cheese made from cow milk in the type of Sjenica cheese were comparatively investigated. Autohtonous Sjenica cheese, made from ewe's milk and Sjenica type cheese made from cow's milk both had high content of moisture (53.46% and 59.56% respectively), which is the result of production process (coagulation time, curd processing, drying and salting). According to moisture content in fat free basis - MFFB (73.51% and 73.38% respectively) both cheeses belong to soft cheeses group, and according to fat in total solids - FTS (58.66% and 46.75% respectively) they belong to a group of whole milk cheeses. Ripening coefficient of Sjenica cheese made from ewe's milk (21.42%) was larger than ripening coefficient of Sjenica type cheese made from cow's milk (20.41%). Big differences in chemical composition of both cheeses are due to non-uniformly technology, which imposes need to assimilate technology process of Sjenica cheese production and fulfill geographic origin protection of Sjenica cheese as autohthonous cheese characteristic for wider area of Sjenicko-pesterska plateau.
