Meat production from dairy breed lambs due to slaughter age and feeding plan based on wheat bran
2019
This experiment aimed to investigate the possibility to increase the carcass weight of dairy breed lambs and produce moderate-fat meat by applying inexpensive feeding strategies based on restriction and through the use of a fibrous byproduct such as the durum wheat bran (DWB). Sixty-five 45-day-old lambs of the Valle del Belice breed, divided into 6 groups, were fed alfalfa hay supplemented with concentrate feeds including DWB at 0% or 20% (DWB0, DWB20), supplied ad libitum (L) or restricted at 75% (R), and slaughtered at 90 or 120 days of age. The groups were as follows: DWB0-90L (n = 14), DWB20-90L (n = 14), DWB0-120R (n = 10), DWB20-120R (n = 9), DWB0-120L (n = 9), DWB20-120L (n = 9). Th…
Oxidative Status of Goats with Different CSN1S1 Genotypes Fed ad Libitum with Fresh and Dry Forages

Effects of the foal at the milking and dietary supplementation with extra virgin olive oil on jennet milk production
2009
The effects of the foal at the milking and the extra virgin olive oil supplementation in the diet, on the milk obtained by 12 Ragusana jennets were studied. The jennets were each fed 3.5+1.5 kg/d of concentrate+bran, and hay ad libitum. They were divided into 2 equal groups with one group receiving an additional dietary supplement of 100 ml/d of olive oil. Milk was collected at day 20 post foal- ing and every 15-18 d for 5 times. At each collection period jennets were milked 4-times per day. At 07:30 h foals were separated from the jennets and after a 4 hour interval were milked manually (1MNF;1st milking, foal absent). At the end of the 1MNF, each jennet was milked again, with the foals ke…
Introdurre la crusca di frumento duro nelle razioni alimentari dei ruminanti
2017
La crusca, sottoprodotto dell’industria molitoria del frumento, è un ingrediente utilizzato per la formulazione di mangimi zootecnici. Per la sua composizione chimica, che evidenzia una discreta dotazione di carboidrati strutturali, risulta più conveniente l’impiego per le specie ruminanti, soprattutto nel sud Italia, dove risulta facilmente reperibile a prezzi contenuti. L’uso della crusca potrebbe risultare conveniente anche perché contiene acido ferulico, composto polifenolico dotato di caratteristiche nutrizionali positive in grado di migliorare il bilancio antiossidante degli animali e garantire la produzione di alimenti destinati al consumo umano dotati di caratteristiche nutraceutich…
Effects of grazing on welfare and production traits of organic dairy cows
2013
In organic livestock systems, grazing is the preferred feeding source, especially for animal welfare and health implications, but it is not an obliged practice. In order to contribute on this topic, in an organic dairy farm, grazing was compared with permanent free-stall housing using two homogeneous groups of eight Bruna cows allocated to the following regimes: (G) grazing on barley grass for 5 h/d, and then kept in a free-stall structure and fed with unifeed, composed of hay and concentrate; (S) kept in a free-stall building for 24 h/d and fed with a diet based on the same unifeed. Comparison was based on milk production, behaviour, immune responses, metabolic status and oxidative stress …
Effects of Sulla forage (Sulla coronarium L.) on the oxidative status and milk polyphenol content in goats
2015
Abstract Twelve milking Girgentana goats were allocated into 3 groups and fed 3 diets ad libitum in a 3 × 3 Latin square design with 3 periods. The diets were Sulla fresh forage ad libitum (SUL), Sulla fresh forage ad libitum and 800 g/d of barley meal (SULB), and mixed hay ad libitum and 800 g/d of barley meal (HB). Changes were observed in total polyphenol intake, plasma oxidative status, plasma polyphenol content, metabolic status, milk polyphenol content, and total antioxidant capacity. The fresh forage diets (SUL and SULB) increased dry matter, total polyphenol, nontannic polyphenol and tannin intakes, and the milk total protein, casein, milk total polyphenols, and milk free polyphenol…
Effects of adding solid and molten chocolate on the physicochemical, antioxidant, microbiological, and sensory properties of ewe's milk cheese.
2020
Abstract: A novel dairy product, namely “chocolate cheese”, was produced with two typical Sicilian food products: Pecorino cheese, processed from ewe's milk, and Modica chocolate. The cheese, manufactured with 0%, 5%, 10%, and 15% (w/w) solid or molten chocolate, was evaluated after 0, 2, 4, and 6 weeks of vacuum storage for its nutritional and health properties. The addition of chocolate reduced the pH, protein, fat, and ash; the addition of 5% or 10% molten chocolate reduced hardness (N/mm2). The addition of either solid or molten chocolate resulted in a slight increase (P < 0.1038) in the total polyphenol content, a higher oleic acid content, and less oxidative stability. The microbio…

Improvement of Oxidative Status, Milk and Cheese Production, and Food Sustainability Indexes by Addition of Durum Wheat Bran to Dairy Cows’ Diet
2019
Durum wheat bran (DWB) is a by-product mostly used in feeding ruminants, contributing to decrease in the utilization of feeds suitable as foods for human consumption, thus improving the sustainability of livestock production. However, the potential benefits of DWB, due to its content in phenolic acids, mainly consisting of ferulic acid with antioxidant properties, have not been well clarified yet. Accordingly, in this experiment, 36 lactating cows divided into three groups received, over a period of 100 days, one of three concentrates including DWB at 0% (DWB0), 10% (DWB10), or 20% (DWB20). The concentrates were formulated to be isoproteic and isoenergetic and, to balance the higher fiber c…
