Abstract There is no standard limit value for somatic cell count (SCC) of raw goat milk in the EU despite that excellent hygienic quality milk is needed for the manufacture of fermented milk products or cheese varieties. Mastitis often results such high SCC - besides the potential risk for humans - that the clotting of milk will not be perfect, resulting slack curd with higher whey releasing; furthermore, wrong structure, ripening, bad sensory properties of cheese can also be its consequences. In this paper, we report the SCC of milk samples from five different goat breeds bred in Hungary, measured with two fast methods compared with the results from the reference method. Furthermore, we investigated the applicability and the accuracy of the MT-02 (Agro Legato Ltd., Hungary) instrument. We determined that the White Side test and the instrument MT were suitable for the estimation of possible risks and consequences in the case of the use of high SCC milk before production. The general summarized average milk SCC was 6.64 × 105 ml−1. The highest difference between the results from MT-02 and the fluorometric (reference) method was 5 × 105 ml−1, but it was a singular, extreme value. The r2 of the calculated linear calibration equation was 0.7819; consequently, this method seems to be applicable in the measurement of SCC with MT-02 instrument. Furthermore, the SCC of samples did not differ significantly by genotypes and by seasons (spring: 5.85 × 105 ml−1, autumn: 6.22 × 105 ml−1).

The Relationship

This work is aimed at prediction and quantification of goat milk yield (MY, kg) losses by the somatic cell count (SCC, 103.ml−1) in milk recording. The goal is to support the prevention of milk secretion disorders, milk yield and quality. During two years there were evaluated composition and properties of individual milk samples (n = 1 173). There were included animals of brown short‑haired (BSH) breed and BSH × white short‑haired in one flock. The linear and nonlinear regression, interpolation, extrapolation, approximation and qualified estimation were used for milk losses prediction along the SCC. The relevant values of the SCC arithmetic and geometric mean and median and MY arithmetic mean were: 1,400 103.ml−1 (with high variability of 128 %), 745 and 747 103.ml−1; 2.94 kg/ day. The relationship between fat and crude protein had a correlation coefficient of 0.395, P < 0.001. There were stated the correlations between SCC and: lactose −0.416, P < 0.001; solids non fat −0.25, P < 0.001; MY −0.135, P < 0.01. The relationship between SCC and MY was negative along months, 6 cases out of 7 and significant in March and May (P < 0.05 and P < 0.01). For instance predicted MY for SCC intervals 1–1.999, 2–2.999, 3–3.999, 4–4.999, 5–5.999, 6–6.999 and ≥ 7 thousands 103.ml−1 may be 3.99, 3.77, 3.6 , 3.46, 3.33, 3.23 and 3.13 kg in 3rd month etc. The corresponding MY losses by SCC are evident from this trend. The result use is focused on the original dairy goat farm and use elsewhere is possible in farms with similar SCC, goat milk yield and rearing system.

The Direct Microscopic Somatic Cell Count (DMSCC), developed to meet the need for a closely standardized reference method in an abnormal milk control program, requires the use of a specified single-band eyepiece reticle chosen to yield optimum precision for cell counts in the region of the Control limit. We have adapted the techniques of the DMSCC and the statistical model for its evaluation to mastitis research, in which quarter milk samples may require precise counting over an extreme range of cell concentrations. A special reticle provides a choice of 2 band widths, and 1, 2, or 4 strips are counted. The area of milk film to be examined differs for each of 6 Concentration ranges, identified by a preliminary estimation of cell density and by the count on the first strip. Except in the lowest range, in which the number of cells counted may be as low as 0, total cells counted vary only between 400 and 800 and the expected coefficient of variation between 5.0 and 3.5%. Above the maximum concentration of 18 × 106/ml a field-strip method extends the usable range to 70 × 106/ml at a constant coefficient of variation of 5.0%.

This paper presents an alternative method to estimate somatic cell count (SCC) in cows' milk. SCC is an important indicator in the detection of inflammatory reactions within the udder in cows and Direct Optical Microscopy (DOM) is the present reference method for SCC but, owing to its dependence on human operators, it is extremely costly, time-consuming and potentially subjective. The industrial method of choice is Epifluorescence (EF), which has the potential for impressive throughput and acceptable precision, but requires huge inversions and handling of highly toxic reactives and waste. In this paper, an advantageous method that involves application of a low-cost Video Microscopy (VM) system is analysed and discussed, including a comparison between DOM and VM, and an example of application of both methods to evaluate EF counts. We conclude that VM is sufficiently precise and very cheap to implement and operate.

Abstract. The aim of this study was to estimate an influence of supplementation of exogenous N-acetylcysteine (NAC) on the somatic cell count (SCC, quantified as cells per ml) and chemical composition of goat milk. The study was carried out on 15 goats, in the last part of lactation (220-250 days). The animals were divided into 3 groups according to SCC in their milk: 1st – up to 2×106, 2nd – from 2 to 4×106 and 3rd – above 4×106. The animals were clinically healthy. They were given NAC in the amount of 12 mg/ kg of live body weight per os for 7 days, once a day, during evening milking. Milk yield, as well as fat, protein and lactose contents and SCC were studied three times: 1st – just before starting the experiment, 2nd – after 7 days of NAC application and 3rd – a week after the end of NAC application. The analysis of variance with General Linear Model (GLM) procedure of SAS® package was used. There was observed the significant decrease of SCC after one-week supplementation of NAC and stagnation of SCC after next week in all three groups. The changes of chemical composition of milk were not significant. The significant decrease of SCC may indicate improvement of health of mammary gland. The oxidation processes might be decreased and probably the increase of immune defence of organism took place. One can suggest that the supplementation of NAC may lead to improvement of goat udder health.
