Improvement of Dairy Farms Management of Appenino Campano Area Producing Milk: “Nobilat”
The aims of the present study were: (i) to explore the microbial community of biofilms collected from 11 different Tinas of Hyblean area of Sicily and of milk samples both inoculated and incubated with biofilm; (ii) to identify the VOCs generated in the incubated milk samples; and (iii) to correlate the VOCs formation with the detection f LAB species.
Stage of lactation and corresponding diets affect in situ protein degradation by dairy cows
Our objectives were (1) to measure and compare in situ ruminal CP degradation parameters and RUP of selected protein sources and TMR samples in dairy cows fed diets for 3 stages of lactation, and (2) to determine the hydrolysis time needed for an in vitro Streptomyces griseus procedure that would generate extent of undegraded CP corresponding to in situ RUP
measurements.
Volatile profile differences between spontaneous and cultivated Hyblean pasture
This study was conducted to investigate and detect differences in aroma-active compounds found in the forage of two Hyblean pasture types: cultivated vs. spontaneous.
Association of total mixed ration particle fractions retained on the Penn State Particle Separator with milk, fat, and protein yield lactation curves at the cow level
The objective of this study was to assess the association of particle size in TMR estimated using the Penn State Particle Separator with production of milk, fat, and protein on a representative sample of Ragusa dairy farms, while controlling for nutrient content.
Aromatic and Nutraceutic Components in “Nobilat” Milk Produced in Appennino Campano Area
The scope of this study was to analyze aromatic and nutritional properties of raw and pasteurized “Nobilat” milk from Appennino Campano (Castelpagano, Campania Region) area and to compare it with high milk quality ones.
Effect of Sicilian pasture feeding management on content of α-tocopherol and β-carotene in cow milk
The aim of the present study was to investigate quality of spontaneous and cultivated pastures and pasture feeding management on Sicilian dairy farms during spring by evaluating α-tocopherol and β-carotene contents of pasture milk under ordinary Sicilian farming conditions.
A multilevel model with clustered management practices differentiating dairy herd environments in southeastern Sicily
The objective was to evaluate a methodology where herd environmental opportunity is specified as afunction of inputs administered through practices ascertained from herd manager interviews comparing it with the frequently-usedHYSD criterion ignoring this causal information.
Selected lactic acid bacteria as a hurdle to the microbial spoilage of cheese: Application on a traditional raw ewes’ milk cheese
The specific objectives for this study were: to isolate and select starter LAB (SLAB) from acidified PDO Pecorino Siciliano curds; to select non-starter LAB (NSLAB); to produce experimental cheeses with different inocula of SLAB alone or in combination with NSLAB autochthonous for PDO Pecorino Siciliano cheese; to evaluate the improvement of the hygienic conditions of the final products and the preservation of their typical properties by sensory analysis.
Standardization of procedures for nitrogen fractionation of ruminant feeds.

Variability of volatile profiles in milk from the PDO Ragusano cheese production zone
Native pasture has been shown to have a strong influence on the sensory characteristics of dairy products. However, few studies have been carried out on milk flavor profiles. The aim of the present study was to evaluate the influence of cows’ pasture-based feeding on milk volatile profile.
