Feeding and management techniques to favour summer sheep milk and cheese production in the Mediterranean environment
2015
Sheep milk production in summer can lead to a diversification of milk products and to a more regular product distribution in the market throughout the year. However, in Mediterranean countries small ruminant production cycles are subjected to seasonal variations in forage resources. During summer, a key period for out of season production systems, nutrition plays a fundamental role in regulating the quantity and quality of milk production. In this review, feeding strategies and techniques that could be applied for out of season production in dairy ewes under different Mediterranean conditions are described for intensive, pasture-based and mixed systems. The most common feeding strategies us…
Effect of β-lactoglobulin (LGB) and k-casein (CSN3) alleles on some characteristics of milk produced by Cinisara cows
2015
It is well known that β-lactoglobulin (LGB) and k-casein (CSN3) alleles affect milk cheese making properties. The purpose of this study was to analyse the A and B allele distribution at the LGB and CSN3 loci in Cinisara breed and their influence on milk and cheese making production traits. The Cinisara is a Sicilian breed which, according to DAD-IS database (FAO), consists of about 5,000 individuals and is reared mainly for milk production which is usually transformed into Caciocavallo Palermitano, a typical stretched-curd cheese. We typed 314 lactating cows at the LGB and CSN3 loci by means of RFLP-PCR analyses. The frequencies of LGB A and B alleles were 0.22 and 0.78, respectively; the f…
Milk quality as affected by grazing time of day in Mediterranean goats.
2008
We evaluated the effect of grazing time of day on goat milk chemical composition, renneting properties and milk fatty acid profile in a Mediterranean grazing system. Sixteen lactating Girgentana goats were divided into two experimental groups and housed in individual pens, where they received 500 g/d of barley grain. For 5 weeks the two groups were left to graze in two fenced plots on a ryegrass sward as follows: morning group (AM), from 9·00 to 13·00; afternoon group (PM), from 12·00 to 16·00. In selected herbage, water-soluble carbohydrates (WSC) increased in the afternoon (204 v. 174 g/kg dry matter, DM; P=0·01), whereas crude protein (CP) and linolenic acid decreased (respectively, 16·7…
The influence of somatic cell count on sheep milk composition and cheese-making properties
2005
Somatic cell count (SCC) is an important tool for monitoring intramammary infections in dairy cows. However, systematic generalization of this decision rule is not easy in small ruminants. Determination of SCC in sheep milk is important for the processors of milk (indicator of quality), for breeders (mastitis indicator) and could be useful for selection as well. SCC value can be affected by some non-infective factors such as breed, stage of lactation, parity, type of lambing, type of milking, etc. (Bergonier et al., 1994), as well the health status of the udder (Fruganti et al., 1985; Ranucci et al., 1988). In addition, EC Directive 92/46, which regulates the production and commercialisatio…
