Finnsheep ewes were tested for milk quality and productivity (lambs and wool) on an experimental farm in two years. Milk samples were taken in first, second and third month of lactation to qualify somatic cell count (SCC) and percentage of fat (F %), protein (P %) and lactose (L %). For the calculation, logarithmic SCC (LSCC) was used. Data concerning rearing of lambs and wool production were calculated with each sample during lactation. Differences in all tested traits were found. Season 1981 proved to be better than 1983. For all observations LSCC was 2.16 and milk composition as follows: F % 5.38, P % 5.42 and L % 4.74. From average ewe there were 2.42 born lambs (6.18 kg), 1.14 weaned lambs (20.09 kg) and 1.24 kg of wool for six months. Correlation coefficients between LSCC and traits tested were; F % 0.07, P % —0.02, L %— 0.53, wool yield — 0.09, number of weaned lambs — 0.01, weight of weaned lambs 0.00. For all above coefficients the error was 0.05. Those tests concerned limited number of animals and will be continued.

The major alteration in the milk composition due to mastitis includes presence of somatic cells (neutrophills, monocytes, macrophages and mammary epithelial cells), bactericidal and bacteriostatic compounds and certain enzymes. Antibiotic residue violation and presence of foodborn pathogens with/without their toxins is another threat of immense importance. These changes in the milk account for the deterioration of the milk quality, risk of health hazards and also its acceptance in the international market. Of all these components, milk somatic cells are the single most widely used indicator of the udder health and mastitis. Somatic cell count (SCC) is used as a system for measurement of milk quality internationally. Strict legislation for monitoring the minimum SCC level is followed to ensure healthy milk in most of the developed countries. This paper introduces the concept of ‘Clean White Revolution’ and reviews the importance of SCC as a measure to ensure hygienic milk production in India. It also emphasizes upon a need to strengthen the existing legislations concerned.

Abstract. The aim of this study was to determine the effect of somatic cell count (SCC) on milk yield and composition using a threshold value of 250 ∙103 cells/ml in dairy ewes of line 05. A total of 1 512 milk samples from udder halves were collected throughout milking periods at monthly intervals. In the present study milk composition (from halves of the udder) and daily milk yield (from udders) was examined in terms of SCC in ewe milk in three groups: from both halves of the udder below 250 ∙103 cells/ml, from one halves of the udder below 250 ∙103 cells/ml and from second half udder above 250 ∙103 cells/ml and from both halves of the udder above 250 ∙103 cells/ml. Milk yield from udders, somatic cell count in milk samples from udder halves and milk composition depended on the level of SCC recorded for halves of the udder. Somatic cell counts in milk from one or both halves of udders exceeding 250 ∙103 cells/ ml resulted in a statistically significant (P<0.01) decrease in daily milk production of ewes, by approx. 15.89 and 30.22 %, respectively. The analysis of variance showed also a significant effect of parity and stage of lactation of ewes on somatic cell count (log SCC) and milk composition from udder halves below 250 ∙103 cells/ml.

The Impact

A total of 50 sheep milk samples during lactations were used to investigate the impact of subclinical mastitis induced Somatic Cell Count (SCC) increase on changes in chemical composition in milk. Samples were collected and analyzed for fat, protein, lactose, solids non-fat (SNF) and total solids (TS) and SCC. Within three stages of lactation, all milk samples were analyzed for three times. The highest average of SCC was recorded in ewes aged 4 years (46.67) while lowest average was recorded at the age of 3-3.5 years (34.24%). Protein content was highest at ewes aged 1-1.5, whereas highest lactose percentage recorded at ewes aged 3-3.5. In conclusion, in high SCC milk, lactose content may be more indicative of SCC level than milk fat, protein, SNF and TS during lactation. Age of ewes is an important factor affecting milk composition, thus is a necessary parameter in optimizing sheep milk quality in conditions of subclinical mastitis.

Milk Samples

Less than half of Australian dairy farmers undertake production recording that normally requires the collection of milk samples for the measurements of fat, protein and lactose percentages and somatic cell count. Usually the milk samples are collected from individual animals on a ‘one-day-per-month’ basis by temporary milk-metering or sampling devices. Farmers who do not participate in production recording programs may be encouraged to do so if they could use a simple, robust, inexpensive, convenient and precise sampler. A sampler has been developed to meet these criteria. In this paper we report on the precision and bias of the new sampler with respect to milk composition and somatic cell count by comparison with samples collected by test buckets. For milk fat, the precision was only 3.1% and bias was +0.002% coefficient of variation. Precision for fat yield over a lactation period increases by only 0.02% when compared with results based on samplers that are approved by the International Committee for Animal Recording. We consider that the combination of low sampler cost and low sampler errors makes the new sampler aptly suited for production recording and monitoring somatic cell count.

Abstract An effect of mammary gland infection caused by Streptococcus uberis on the changes in cows’ milk composition and its physicochemical properties was examined. The study was conducted in the herd of Slovak Pied breed cattle (with a share of HF blood), in 2nd and 3rd lactation, after 4th month of milking. Milk samples were collected from a quarter milking. The samples were subjected to microbiological analysis, basic milk composition, total bacteria count, somatic cell count and physicochemical properties were examined. Also analyses of protein fractions share and fatty acids profile were conducted. An effect of bacterial infection of the mammary gland bring an increase (P<0.01) in somatic cell count was observed in this study. Milk samples contaminated with S. uberis were characterized by higher (P<0.05) total bacteria count and total protein compared to milk samples collected from non-infected mammary gland. The level of κ-casein was significantly (P<0.05) decreased in cows with subclinical mastitis caused by S. uberis. Significant (P<0.05) reduction in the share of C13:0 acid, and an increased level of C18:0, C18:1n7t and CLA were observed in milk contaminated with S. uberis compared to healthy cows’ milk. It should be concluded that S. uberis causes the increase in total bacteria count, SCC and the decrease in κ-casein level, which significantly affects deterioration of technological quality of cows’ milk.

At dairying cost reduction and effort about maintenance of milk recording (MR) range the MR cost decrease is also important. Aim was to revise the older prediction equations for alternative reduced milk sampling (morning – M or evening – E) for assurance of MR reliable results at twice milking a day (TMD) with balanced interval 12/12. Individual milk samples (n = 619 animals) were obtained during TMD (M, E and REF; n = 1 857 samples). Fat (F), protein (P), lactose (L) and somatic cell count (SCC) were analysed. Czech Fleckvieh and Holstein breeds were included. The reference values (REF) of day milking were obtained in regular MR (A4P). M and E milking results were related to the REF. Older prediction equations with lower validity because of time and breeding were revised: a) for F from M on REF y = 0.6932x + 1.381, where r = 0.752 and P ≤ 0.001; b) for P from M on REF y = 0.9432x + 0.2274, where r = 0.949 and P ≤ 0.001; c) for L from E on REF y = 0.8145x + 0.9095, where r = 0.87 and P ≤ 0.001; d) for log SCC from E on REF y = 0.8829x + 0.2367, where r = 0.94 and P ≤ 0.001. MR cost reduction is possible using method of alternative sampling including corresponding prediction equations.
