“…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. Increased SCC in milk from dairy goat breeds reared in the USA is often, and above 1.000.000/ml as stated by Haenlein (2002). Similar values, even slightly higher for SCC, depending on the order of lactation are stated by Pavliček et al (2006) in Alpine breed goats.…”

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.

“…On the other hand, average SCC in Saanen goats was higher than recommended (Table 1) by Croatian and European Standards (EUROPEAN COMMISION 1995, OFFICIAL GAZZETTE 2000. However, in contrast to dairy cows, individual milk samples for evaluating total SCC in terms of detection of udder infection are less reliable for dairy goats (HAENLEIN 2002, STRZALKOWSKA et al 2006. From the WILSON et al study (1995), as much as 90 % of the differences in goats' SCC were not due to intramammary infection.…”

“…The stage of lactation usually influences the SCC in goats, but also age, level of milk production and breed may cause significant variations in SCC. HAENLEIN (2002) stated that hand milking may also elevate SCC. Moreover, the reproductive cycle and induction of oestrus were related to higher SCC, suggesting that the increase of SCC could be brought about by the oestrogen-induced proliferation and exfoliation of epithelial cells (MORONI et al 2007) which might cause the average higher somatic cell count in Saanen goats in the present research.…”

Oxidative stability and quality of raw Saanen and Alpine goats milk

et al. 2009

The milk composition and concentration of thiobarbituric acid reactive substances (TBARS) and superoxide dismutase (SOD) activity in fresh and refrigerated raw goat milk of Saanen and Alpine breed at the breeding period were investigated. Low average milk fat, SNF and lactose content were determined in both breeds with no significant differences between breeds regarding the milk yield and milk composition. The significantly higher somatic cell count (SCC) was detected in Saanen goats. The SOD activity and TBARS concentration were significantly higher 14 h after the collection and cold storage in both breeds of dairy goats with no difference between the breeds. In the Alpine goats the TBARS concentration was negatively correlated with urea concentration, and in the milk of the Saanen goats the TBARS was positively correlated with proteins and SCC. The higher SCC in the Saanen goats may have caused higher production of secondary oxidative products catalysed by the enzyme superoxide dismutase from polymorphonuclear granulocytes present in the udder, or by some other enzymes that participate in oxidation of the milk constituents. The energy shortage and protein surplus in the diet of the dairy goats may have induced the higher degree of lipid mobilisation and a consequent increase of polyunsaturated fatty acids (PUFA) that are easily prone to oxidation and formation of the secondary oxidative products.Keywords: goat, raw milk, milk components, peroxidation, quality Zusammenfassung Oxidative Stabilität und Qualität der Rohmilch von Saanen-und AlpenziegenUntersucht wurde die Milchzusammensetzung, die TBARS-Konzentration (Thiobarbitursäurereaktive Substanzen) und die SOD-Aktivität (Superoxiddismutase) in frischer und gekühlter Rohmilch von Saanen-und Alpenziegen während der Fortpflanzungszeit. Zwischen beiden Rassen bestanden keine signifikanten Unterschiede bei der Milchleistung und der Milchzusammensetzung, wobei ein relativ niedriger Fett-, Laktosegehalt und ein niedriger Wert für die Trockensubstanz nachgewiesen wurden. Bei den Saanenziegen ergab sich ein höherer somatischer Zellgehalt (SCC). 14 Stunden nach der Milchgewinnung und Kühlhaltung waren in der Milch die TBARS-Konzentration und die SOD-Aktivität signifikant höher, wobei zwischen den Rassen keine Unterschiede ermittelt wurden. Eine negative Beziehung fand sich zwischen dem TBARS-Wert und dem Harnstoffgehalt bei den MARENJAK et al.: Oxidative stability and quality of raw Saanen and Alpine goats milk 638 Alpenziegen, positiv war bei den Saanenziegen die Beziehung zwischen dem TBARS-Wert und dem Eiweiß-sowie SCC-Gehalt. Der höhere SCC-Gehalt war möglicherweise die Ursache für eine höhere Erzeugung von sekundären Oxidationsprodukten verursacht durch die Superoxiddismutase und den im Euter vorhandenen polymorphkernigen Granulozyten oder anderen Enzymen die an der Oxidation der Milchinhaltstoffe teilnehmen. Energiemangel und Eiweißüberschuss in der Ernährung von Milchziegen verursacht möglicherweise die höhere Lipidmobilisation und folglich die Erhöhun...

Abstract:This study was performed to determine the prevalance, causative microorganisms and antimicrobial susceptibility of microorganisms in goat subclinical mastitis around Hatay. A total of 1010 mammary halves of 505 goats were examined by California Mastitis Test (CMT). The somatic cell counts (SCC) were determined by microscopic method. Isolation and identification of microorganisms were carried out by conventional microbiologic methods. Staphylococci were further differentiated by API-STAPH system. Antimicrobial susceptibility was determined by disc diffusion method. The prevalance of the subclinical mastitis was found 8.71 %. The most prevalent microorganism was staphylococci (71.5%). Microorganisms except Staphylococci were Streptococci (8%), Bacillus spp. (5.7%), Escherischia coli (4.5%), Corynebacterium spp. (3.4%), Pseudomonas spp. (2.3%) and Acinetobacteri spp. (2.3%). In addition, mix infection was defined in 2.3% of samples. Highly resistance was found against penicilin, erythromycin, oxytetracycline, gentamicin, amoxicillin. Slightly resistance was found against enrofloxacin, amoxicillin-clavulonic acid, kanamycin plus cephalexin and there was no resistance against cefalotin. It was concluded that, prevalance of subclinical mastitis should be cared; also staphylococci especially Coagulase negative staphylococci are the most commonly isolated bacteria in subclinical mastitis around Hatay. In goat mastitis diagnosis strong positive CMT results should be cared. CMT and SCC results should be supported with microbiologic tests. 3) de izole edildi. Ek olarak örneklerin % 2.3'ünde miks enfeksiyon saptandı. Antibiyotik duyarlılık testlerine göre penisilin, eritromisin, oksitetrasiklin, gentamisin, amoksisilin'e karşı yüksek oranda direç gözlendi. Enrofloksasin, amoksisilin klavulonik asit, kanamisin ve sefaleksin'e karşı orta düzeyde direnç saptanırken, sefalotine karşı direnç yoktu. Sonuç olarak Hatay çevresinde keçi sürülerinde subklinik mastitisin prevalansının dikkate değer seviyelerde olduğu, koagülaz negatif stafilokokların en fazla izole edilen mikroorganizmalar olduğu belirlendi. Keçilerde subklinik mastitis tanısında kuvvetli CMT reasksiyonlarının dikkate alınması gerektiği, CMT ve somatik hücre sayılarının mikrobiyolojik yöntemlerle desteklenmeleri gerektiği kanısına varıldı.
