“…Somatic cell count in the second and the third lactation was 1.11x10 3 and 1.36x10 3 whereas in the fourth and later lactations it was the highest with average value of 1.42x10 3 . Similar values in regard to somatic cell count in goat milk, depending on the order of lactation, were reported by Raynal-Ljutovac et al (2006). Kozačinski et al (2002) established in goat milk average SCC of 1.300.000/ml and concluded that the limit for SCC in goat milk can be over 1.000.000/ml, which is in accordance with results obtained in this study.…”

Nowadays in some west European countries increase the need of rabbit meat. The production of rabbit?s meat in these countries is based on some practical knowledge and methods of selection and breeding. The success in production of this kind of meat depends from the rabbit?s fat or from the quality of the body during the transport (confectioning meat). That is the reason why in these countries the selection of rabbits is making with a big attention. That is why is important to examine the phenotypic connection of the slaughter?s characteristics during the confirmation of the optimal selective criterion. The mass of the thighs and the mass of the muscle layer of the thighs are very important for the rabbit?s selection. The thigh?s mass has strong phenotypic correlation and full genetic correlation with the mass of the clean body. The purpose of this investigation is to find the range of connection of the thigh?s dissection based on correlative and regressive analysis in the prediction of the thigh?s meat contribution and also from the clean body. Based on the obtained results we can conclude that the mass of the thighs is a reliable indicator as to the yield of the thigh as for the whole body musculature.

“…Results demonstrate that all isolates presented antimicrobial activity against both Grampositive and Gram-negative bacteria, and against spoilage and pathogenic bacteria. Previously, antimicrobial activity against microorganisms involved in mastitis and other diseases of sheep flock was also reported (7,26,35). As shown in Table 1 On the other hand, antimicrobial activity against Enterococcus faecalis was not observed (Table 1).…”

Lactic acid bacteria (LAB) were isolated from ovine milk and cheeses manufactured in the South Region of Brazil. Among 112 bacterial isolates investigated, 59 were chosen through a screening for LAB. Among these 59 strains of LAB, 21% showed antimicrobial, proteolytic and lipolytic activities. Based on this screening, Lactobacillus plantarum LCN 17 and Lactobacillus rhamnosus LCN 43 were selected and tested for the production of bacteriocin-like substances (BLS). The BLS produced by both isolates showed antimicrobial activity against Listeria monocytogenes, whereas that produced by L. plantarum LCN 17 presented higher stability to different temperature, pH and enzyme treatments. These strains present potential for production of BLS, and for use as starter cultures.

Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 2, pp. 87-100 Somatic cell count (SCC) is an indicator of mammary gland health state. Lactose (L) can be reduced with mastitis and SCC increase. Mammary gland health is an essential factor of milk quality. Monitoring of mammary gland health is important for prevention and treatment of milk secretion disorders. The goal of this work was to analyse the relationship between SCC and L in various biological species. 7 sets of individual and bulk milk samples (MSs) were analysed (n = 479, 479, 345, 80, 90 and 102) for SCC and L content. 3 sets were with cow (C) milk and 1 set with goat (G), 1 with sheep (S) and 1 with human (H) MSs. The relations in C milk were used as reference. SCC geometric means were markedly lower in C milk (62, 99 and 81 10 3 . ml −1 ) and H milk (103 10 3 . ml −1 ) as compared to small ruminants (G 3 509 and S 609 10 3 . ml −1 ). The mean L values were lower in small ruminants (G 4.36% and S 4.42%) as compared to C milk (4.95%, 4.97% and in 1st lactation 5.10%) and higher in H milk (5.77%). L contents in Czech Fleckvieh and Holstein correlated negatively to SCC (log SCC)) in all lactations (−0.36 P < 0.001 and −0.33 P < 0.001). L content in 1st lactation correlated with SCC markedly narrower than in cows for all lactations (−0.49 P < 0.001). The SCC×L relationship in G (White short-haired) milk (−0.35 P < 0.01) was in good relation to C milk and in S (Tsigai) milk (−0.51 P < 0.001) was markedly narrower as in C and G milk. Lower mean SCC in H milk as compared to G and S milk and comparable to C milk did not show signifi cant negative relationship to L which was 0.08 (P > 0.05) for original SCC values. Surprisingly there was not found the SCC×L relationship in H milk which could be comparable to other mammal species milk. It could be caused by bacteriologically negative results in MSs with higher SCC (> 300 10 3 . ml −1 ). As well as at C milk also at G and S milk and in contrast to H milk it is possible to use the SCC×L relationship for improvement of result interpretation and prevention control in occurrence of milk secretion production disorders in routine monitoring systems such as milk recording with individual MSs and milk quality control with bulk MSs. The quality of decision-making schemes in algorithms for practical monitoring of mammary gland health could be improved. cow, sheep, goat, human milk, milk secretion disorders, lactose, somatic cell count, regression, milk recording Disacharid laktóza (L; C 12 H 22 O 11 , glukóza a galaktóza) je specifi ckým produktem laktogenní syntetické činnosti mléčné žlázy.
