Effects of intramammary infections on somatic cell score and milk yield in Sarda sheep

“…Even in large production systems, random environmental influences, such as availability of feed and climatic events, affected daily milk yield over a 60-day period (Pulina et al 2005).…”

Effect of wheat middlings-based total mixed ration on milk production and composition responses of lactating dairy ewes

“…The following measurements were made: total protein (N × 6.38) according to (AOAC, 2000), fat and lactose content, using an infrared spectrophotometer (Milko-Scan 133B; Foss Electric, Hillerød, Denmark), casein content (AOAC, 2000), and SCC, using a Foss Electric Fossomatic 90 cell counter. Milk production was standardized to 6.5% of fat and 5.8% of protein according to Pulina et al (2005). Milk pH was measured using a pH meter with a temperature probe (expandable ion analyzer model EA940 and electrode Ross model 81-02; Research Inc., Boston, MA).…”

The Effect of the Lactation Stage on Milk Yield, Composition and Renneting Parameters of Milk in Sheep Reared Under Intensive Nutrition

“…Milk yield (MY) and composition of sheep milk can be affected by a lot of factors such as nutrition, stage of lactation, breed and health (Sevi et al, 2004;Pulina et al, 2005). Milk coagulation properties and curd quality (CQ) of sheep milk are also influenced by a lot of factors, while the most important ones are the contents of protein and casein, calcium concetration, pH, titratable acidity and also somatic cell count (Pellegrini et al, 1997;Jaramillo et al, 2008).…”
