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.
How do dairy cows chew?—Particle size analysis of selected feeds with different particle length distributions and of respective ingested bolus particles
The objective of our study was to measure lengths and DM proportions of selected feed and their respective bolus particles with lengths of at least 5 mm. Particles with these lengths were considered to be potentially retained in the rumen. The data were used to estimate particle size reduction during ingestive mastication and to examine the relationship between feed and bolus particle distribution to investigate the influence of initial feed particle size on bolus particle size.
Bagnatura diretta delle bovine benefici su fisiologia e produzione
Effetti di differenti sistemi di raffrescamento in una stalla per vacche da latte in clima mediterraneo. da una prova condotta in provincia di Ragusa, presso un’azienda zootecnica sita ad Acate in provicia di Ragusa ad una altitudine di 234m dal livello del mare. Prova articolata in due anni. Il primo anno è stato utilizzato l’esistente impianto di raffrescamento, durante il secondo anno. è stato utilizzato un sistema di bagnatura diretta degli animali, accoppiato a ventilazione forzata, appositamente progettato ed installato.
INFLUENZA DI ESSENZE AROMATICHE DI CITRONELLA E GERANIO SULLA QUALITÁ AROMATICA DEL LATTE
Lo scopo di tale lavoro è stato di verificare l’influenza del trattamento a base di citronella e geranio sulla qualità aromatica del latte. I risultati delle analisi strumentali indicando una differenza aromatica tra i differenti campioni di latte ed un effetto quindi del trattamento degli animali con la miscela testata sulla qualità aromatica del latte.
Data handling and processing to evaluate dairy farm management through a web application.
The objective of this project therefore goes beyond the simple locally developed farm management. In order to facilitate decision-making an online service was created offering to every farmer the possibility to check via the web the activity being carried out in the farm in order to improve productivity and reduce operating costs.
Objective estimation of body condition score by modeling cow body shape from digital images
The aim of the present study was to develop a technique to model the body shape of a cow from which learned parameters could be used in BCS estimation. A further objective was to build a benchmark data set useful for dairy cattle research purposes, available.
through the Internet.
Prevalence of Mastitis Pathogens in Ragusa, Sicily, from 2000 to 2006
The objective of this study was to report the prevalence of intramammary infections (IMI) in Ragusa, Sicily, from milk samples (n = 18,711) collected between October 2000 and June 2006 from 101 dairy herds.
Body Condition Assessment Using Digital Images
The purpose of this project was to assess the utility of using digital or video images to evaluate the BCS of a group of cows. Our second aim was to construct a model to determine the sample size needed to estimate the mean BCS of
a group of dairy cows.
