Conservation status and historical relatedness of Italian cattle breeds

2018

Background In the last 50 years, the diversity of cattle breeds has experienced a severe contraction. However, in spite of the growing diffusion of cosmopolite specialized breeds, several local cattle breeds are still farmed in Italy. Genetic characterization of breeds represents an essential step to guide decisions in the management of farm animal genetic resources. The aim of this work was to provide a high-resolution representation of the genome-wide diversity and population structure of Italian local cattle breeds using a medium-density single nucleotide polymorphism (SNP) array. Results After quality control filtering, the dataset included 31,013 SNPs for 800 samples from 32 breeds. Ou…

Aseasonal sheep and goat milk production in the Mediterranean area: Physiological and technical insights

2015

Abstract Aseasonal or out-of-season milk production for small ruminants raised in Mediterranean areas refers generally to milk having to be produced at a time that corresponds to summer which is when conditions are generally unfavourable with respect to both physiological aspects and nutritional factors related to seasonal climatic trends. In fact, sheep and goat milk production in the Mediterranean basin is mostly based on pasture utilization and thus follows the pasture availability pattern. This causes a strong seasonal pattern to the amount of milk processed by cheese processes plants, with the peak being in the spring, a marked reduction in early summer and nil or low availability of m…

Effect of substitution of barley and tickbean to maize and extruded soybean in the diet on milk and cheese from ewes grazing under two different stoc…

2007

This experiment aimed to verify the effects of a concentrate supplement based on barley and tickbean (BT), compared with a concentrate of maize and extruded soybean meal (MS), on milk and cheese yield and composition of ewes grazing with different stocking rate (SR). Thirty two Comisana ewes, divided into four groups, for 50 days in spring were allowed to graze plots of a mixed sward of Italian reygrass and berseem clover with a low (LSR, 23 ewes/ha) or a high SR (HSR, 38 ewes/ha) and fed BT or MS. Herbage allowance per ewe was more than double at LSR compared to HSR (P<0.001), and daily milk yield was 10 to 15% higher (P<0.01) in the LSR-BT ewes than in the other groups. Milk composition, …
