Evaluation of somatic cells in ewe's milk [Sardinia - subclinical mastitis]

1998

إنجليزي. The reliability and effectiveness of the California Mastitis Test (CMT) in identifying the presence of subclinical mastitis in ewes was investigated. The research was carried out in 10 groups of Sarda breed ewes (570) showing no clinical symptoms of mastitis. In 1148 samples of half-udder sheep's milk we performed CMT and bacteriological analysis. The milk yield of each half-udder was collected and weighted and from each sample the following parameters were determined: somatic cell count (SCC) by fluoro-optoelectronic method and the fat, protein and lactose contents (by infrared spectrometry). The CMT score showed a significant effect (P0.001) on SCC, milk production, percentage of protein and lactose. Intramammary infections were found in 17 (2.0%) of samples CMT 0; on 13 (37.2%) CMT 1; in 106 (79.7%) CMT 2 and 107 (94.7%) CMT 3

إيطالي. L'indagine si propone di valutare le possibilita' di individuazione della mastite subclinica nell'ovino. Su campioni di latte di emimammella (n. 1148), prelevati da pecore di razza Sarda (n. 10 gruppi, sono stati eseguiti il California Mastitis Test (score tra 0 e 3, in relazione all'intensita' della reazione), l'esame batteriologico, la determinazione del contenuto in cellule somatiche mediante metodo fluoro-optoelettronico e del contenuto % in grasso, proteine e lattosio. L'esame batteriologico e' risultato positivo rispettivamente in n. 17 (2.0%) dei campioni con score CMT 0; in n. 19 (37.2%) con score 1; in n. 106 (79.7%) con score 2; n. 107 (94.7%) score 3. In relazione allo score CMT sono state osservate variazioni significative (P0.001) del contenuto in cellule somatiche, della quantita' di latte prodotto e della sua composizione percentuale
