Effect of the pasture on milk production from Cinisara cows over the seasons
No full textCinisara is a Sicilian autochthonous breed of dairy cow and its milk is processed to make Caciocavallo cheese. The pasture is the basis of the diet during all the year, but its production is not continuous and homogenous, because of environmental constrains (Alabiso et al., 2005). The feeding integrations are concentrate, hay and or straw, and their quantities given to the animals are different during the year in relation to the pasture resources. The aim of this research was to study the effect of the pasture on milk production from Cinisara cows over the season

At 20, 50 and 90 days post-foaling, each jennet was milked 4 times per day. The feeding system and the milking procedures are given by Alabiso et al. (2009). FA profiles of the composites from milkings without foals (1MNF+3MNF) and with foals (2MYF+4MYF) were analyzed by gas chromatography. Dietary oil had no significant effect on milk yield or fat content but increased the proportion of C18:1 (n-9) in milk. Jen- net milk had a beneficial FA profile compared to bovine milk and thus would be suitable for consump- tion by infants suffering from cows milk protein allergy, however, augmentation of the long-chain n-3 polyunsaturated FA content warrants further study
MABS validation through repeated execution and data mining analysis
No full textAgent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation

No full textUncovering the Fungal Community Composition of Alive and Dead Posidonia oceanica Matte
No full textPosidonia oceanica retains a large amount of carbon within its belowground recalcitrant structure, the 'matte,' which is characterized by low oxygen availability and biodegradation. Fungi may play a pivotal role in carbon sequestration within the matte, even if little/no information is available. To fill this gap, we profiled fungal communities from the upper and lower layers of alive and dead matte, by using an ITS2-5.8S rDNA metabarcoding approach. The study was conducted in a shallow coastal stretch of the Aegean Sea (Crete). Then, 184 operational taxonomic units were identified, predominantly belonging to Ascomycota, in alive and dead matte. Nevertheless, their composition significantly differed: the host-specific Posidoniomyces atricolor was dominant in alive but not in dead matte, while fast-growing saprotrophs, potentially accelerating the decomposition rate, increased in dead matte. These findings lay the groundwork for future investigations on the possible increase of biodegradation under the changing environmental conditions

Effects of a split 48-hour doe-litter separation on productivity of free nursing does and their litters
No full textTo prevent the weight loss of litters, and the distress of both rabbit does and their litters due to doe-litter separation (DLS), without losing its beneficial effects on fertility, the DLS, lasting 48 h before artificial insemination (AI), was split into two periods of 24 h with a short controlled suckling.Initially, 105 does of different parity were divided into three groups. During the post partum, the free-nursing does were treated as follows: regular DLS (R-DLS), the nest-box was closed for 48 h, from days 9 to 11, before AI; split DLS (S-DLS), the nest-box was closed for 24 h and, after suckling, for other 24 h before AI; control, does had free access to the nest-box.Fertility improved (P≤0.05) in both R-DLS (60.9%) and S-DLS (59.4%) does compared to control does (44.1%). R-DLS and S-DLS does showed lower rabbit losses from days 14 to 35 (P≤0.001) and higher litter sizes at weaning (P≤0.05) than control does. Whereas the S-DLS did not affect the growth-rate and the weight of nursed rabbits until the weaning, the R-DLS reduced growth from days 9 to 14 (9.3, 13.2 and 14.0 g/day for R-DLS, S-DLS and control, respectively; P≤0.001) and the weaning weight of rabbits (732, 777, 780 g for R-DLS, S-DLS and control, respectively; P≤0.01). Productivity improved by 35.4% and 44.2% with R-DLS and S-DLS, respectively
VALUTAZIONE DEL LIVELLO DI RIEMPIMENTO DELLA MAMMELLA D’ASINA A DIVERSI INTERVALLI DI MUNGITURA
No full textScopo del presente lavoro è stato quello di valutare il livello di riempimento della mammella d’asina a diversi intervalli di mungitura per definire il numero di mungiture giornaliere e il relativo intervallo che, nel rispetto della fisiologia della mammella dell’asina e del benessere animale, permettano di migliorare la produzione di latte. Durante lo studio differenti controlli batteriologici sono stati effettuati per verificare la qualità igienica del latte, considerando la principale destinazione del latte all’alimentazione dei lattanti affetti da Allergia alle Proteine del Latte Vaccino.
Lo studio è stato condotto su 12 asine Ragusane pluripare in lattazione nel novembre 2011 presso l’Istituto Sperimentale Zootecnico per la Sicilia a 100 m sul livello del mare. Durante la prova gli animali sono stati confinati in un ampio recinto dove venivano alimentati con fieno ad libitum e 3,5 kg/capo/giorno di concentrato. Le asine sono state munte manualmente in presenza del puledro usando diversi intervalli di mungitura: 1, 2, 3, 4, 5, 6 e 12 ore dalla separazione del puledro. Alla separazione del puledro la mammella è stata svuotata con una mungitura preliminare. Il latte munto è stato registrato, e campioni di latte individuale e di massa sono stati raccolti e analizzati per la determinazione dei parametri qualitativi e batteriologici.
La quantità di latte accumulata nella mammella è sempre aumentata passando dalla mungitura effettuata dopo 1 ora a quella dopo 12 ore, mentre il contenuto in grasso ha fatto registrare un andamento opposto. La produzione di latte/ora è aumenta fino a 3-4 ore dalla separazione del puledro, e poi è diminuita negli intervalli di mungitura più lunghi.
Le proteine e il lattosio non sembrerebbero influenzate dall’intervallo di mungitura. Il rapporto NPN/NT si è attestato su valori intorno al 15%.
Il controllo batteriologico specifico ha evidenziato in diversi casi la presenza di Staphylococcus spp. e Streptococcus spp. a cui è corrisposto un maggior contenuto medio in cellule somatiche. Nel latte di un soggetto è stato trovato più volte la Granulicatella adiacens. Le cellule somatiche del latte di massa sono state comprese tra 2.000 e 123.000 cellule/mlThis trial aimed to investigate the level of jennet udder filling at different milking interval, in order to define the daily milking times and the relative intervals improving milk production, while respecting the jennet udder physiology and the animal welfare. During the trial, different bacteriological tests were conducted to check the milk hygienic quality, since the jennet milk is mainly destined to feed young patients affected by Cow Milk Protein Allergy.
The trial was carried out in November 2010 at the “Istituto Sperimentale Zootecnico per la Sicilia” (100 m a.s.l.) using twelve pluriparous lactating jennets. The animals were kept in a large paddock and fed hay ad libitum and concentrate (3.5 kg/day per jennet). The jennets were hand-milked with the foals, using 7 different milking intervals: 1, 2, 3, 4, 5, 6 and 12 hours after the foals’ separation. At the separation, the udder was emptied by a preliminary milking. The milk amounts were recorded, and samples of individual and bulk milk were collected and analyzed for the main quality and bacteriological parameters.
The quantity of milk accumulated in the udder is always increased passing from the milking made after 1 hour to that after 12 hours, while the fat content showed an opposite trend. The milk yield/hour increased up to 3-4 hours from the foals’ separation, and then it decreased at longer milking intervals.
Milk protein and lactose do not seem influenced by the milking interval. The ratio NPN/NT showed values around 15%.
In different cases, specific bacteriological tests underlined the presence of Staphylococcus spp. and Streptococcus spp. in milk, corresponding to a higher content in somatic cells. The Granulicatella adiacens was always found in the milk of one jennet. The values of somatic cells in bulk mass milk ranged from 2.000 to 123.000 cells/m
