ABSTRACT This study evaluates the potential of Fourier-Transform Near Infrared Spectroscopy (FT-NIRS) to estimate chemical composition fresh natural pastures Tuscany without previous drying and grinding. Chemical herbage samples is determined by applying usual chemistry. FT-NIRS calibration cross-validation were developed spectra pre-treatment two statistical models: partial least square regression principal component regression. The results are evaluated in terms coefficients determination...
This study evaluates the potential of Fourier transformation near-infrared reflectance spectroscopy to estimate nutritional value and chemical composition natural pastures. Variability from all samples pastures available is considered in order assess applicability calibration models future predictions. Chemical components (dry matter, crude protein, ash, ether extract, fibre, fibrous fractions) grass were determined by applying official methods, milk meat forage units calculated. Calibration...
Autochthonous pig breeds provide products of differentiated quality, among which quality control is difficult to perform and insufficient for current market requirements. The present research evaluates the predictive ability near-infrared (NIR) spectroscopy, combined with chemometric methods as a rapid affordable tool assure traceability control. Thus, NIR technology was assessed intact minced muscle Longissimus thoracis et lumborum samples collected from 12 European autochthonous...
Near-infrared spectroscopy (NIRS) and closed methods have been applied to analyse the quality of forage animal feed. However, grasslands are linked variability factors (e.g., site, year, occurring species, etc.) which restrict prediction capacity NIRS. The aim this study is test Fourier transform NIRS application in order determine chemical characteristics fresh, undried unground samples grassland located north-central Apennine. results indicated success FT-NIRS models for dry matter (DM),...
Abstract The fatty acids profile has been playing a decisive role in recent years, thanks to technological, sensory and health demands from producers consumers. application of NIRS technique on fat tissues, could lead more efficient, practical, economical the quality control. study aim was assess accuracy Fourier Transformed Near Infrared Spectroscopy determine composition 12 European local pig breeds. A total 439 spectra backfat were collected both intact minced tissue then analyzed using...
Hay is one of the primary constituents ruminant feed, and rapid classification systems nutritional value are essential. A reliable approach to evaluating hay quality a combination visual combined inspection by NIRS analysis. The analysis was carried out on 1,639 samples collected from 2016 2021 in northern Italy. Discriminant (DAPC) five types (FOM, forage mixtures; APG, first alfalfa cutting with prevalence graminaceous >50%; PRA, prevailing PUA, purity >95%; PEM, permanent meadows)...
Frankfurter-type sausages (called sausages) were manufactured using Cinta Senese meat. Two different formulations considered: (i) nitrite and nitrate as curing agents (NIT), (ii) natural mixture (NAT) totally replacing the synthetic agents. Microbiological, chemical, physical characteristics during three storage times (7, 30, 60 days) investigated, while sensorial traits evaluated at end of period. The main foodborne pathogens (Escherichia coli, Listeria monocytogenes, coagulase positive...
Growth performance and meat quality traits of 24 Massese suckling lambs reared up to 69 days age in different farming systems were evaluated. Three groups considered: stall (S) indoors fed concentrate hay; pasture (P) outdoor semi free-range (F) during the night at day, concentrate, hay herbage. The remained constantly with their dams for whole period, having thus always access mothers' milk. Animals weights recorded, and, after slaughtering, carcase considered. Fatty acids composition...

This study aimed to compare the grazing behaviour of two pig genetic types, Cinta Senese (CS) and its crossbreed with Large White (LW x CS), farmed in natural rearing system Tuscany, as influenced by diurnal time slot season year. In situ direct observations on herds pigs were conducted during daylight hours for five consecutive days repeated bimonthly a period one The grouped into three slots relative frequencies main activities obtained. Data subjected ANOVA type, month fixed effects....
This study aims to classify plant communities by applying discriminant analysis based on principal components (DAPC) near-infrared spectra (FT-NIRS) starting from fresh herbage samples. Grassland samples (
Abstract Many studies have reported that the impact of high temperatures affects physiology, welfare, health, and productivity farm animals, among these, dairy cattle farming is one livestock sectors suffers greatest effects. The temperature–humidity index (THI) represents state art in evaluation heat stress conditions but often its measurement not carried out sheds. For this reason, aim study was monitoring THI three farms Mugello (Tuscany) to understand influence on cows. values were...
The aim of this study was to investigate the effect two different feeding managements on growth performance, carcass, and meat traits 40 pigs: 20 Cinta Senese pure breed (CS) Large White x (LWxCS) crossbred pigs. Twenty barrows (10 CS 10 LWxCS) were reared outdoor in a rotational pasture system according farm forage chain; pigs supplemented with concentrate when needed (P); twenty placed into fence as control feed only (F). All slaughtered at 154 kg live weight, average. Carcass dissected...

Soybean meal is the most important protein source in beef cattle feeding. The research of alternative sources to replace soy use, avoiding negative effects on vivo performance and product's quality, an issue. In this context, cardoon represents a non-OGM resilient crop that can be cultivated marginal lands for extracting its seed oil (utilized biodiesel biodegradable bioplastic production) whose residual from could suitable by-product animal feeding, due fairly high content. aim study was...
La valorizzazione dei pascoli naturali attraverso il pascolamento può rappresentare un valore aggiunto negli allevamenti zootecnici sia in termini economici relativamente alla qualità prodotti che ne derivano. Tuttavia, la conoscenza e comprensione delle strategie di è fondamentale per uso efficiente risorse naturali. Questo studio ha lo scopo confrontare comportamento alimentare suini due tipi genetici: razza autoctona Cinta Senese suo incrocio con Large White. I avevano a disposizione...
The study investigated the relationship between temperature humidity index (THI) and behaviour of 24 young fattening Limousin bulls reared in two farms Tuscany, Italy. In each farm, six animals were undergone to ceiling fans (switched on at THI values up 72), represented control group. trial lasted three days for consecutive weeks August 2020. Behavioural observations conducted using scan sampling technique eating, ruminating, drinking, resting other social activities registered every 5 min,...
Fresh samples of Longissimus thoracis Charolais (n = 12), Romagnola 15), Limousine 77), and crossbreed 62) animals were evaluated with different storage periods (0, 4, 9, 14 days). Proximate analysis (i.e., pH, humidity, color, free water content, physical parameters) was performed for each sample. The data obtained a mixed model, setting 5 fixed effects (breed, time, age, EUROP conformation, number animal transports) the as random. results demonstrated that meat quality affected mainly by...
