Sensory quality of meat from lambs fed on different diets

The whole seed of sweet lupin var. Multitalia with a protein content higher than 35% and a low content in alkaloids constitutes a good protein source alternative to soybean meal, today deriving for more than 60% from OGM (Genetically Modified Organisms) cultivation. Moreover, the poor national production and the cost of feeds for animals forces the livestock compartment to utilize alternative biomasses the availability of which highly depends on from the environment and the season

evaluation of animal welfare and milk production of goat fed on diet containing hydroponically germinating seeds

Hydroponic fodder is a particularly nutritious feed, rich in protein and vitamins such as ß-carotene, trace elements and enzymes. It may also offer the advantage of a continuous availability. A pilot plant for hydroponically production of germinating seeds was built in an area of the same farm where the trial took place. Three homogeneous groups of 30 Jonica breed goats in lactation (4th-5th parity) were used to evaluate the effects of two different levels of partial dietary substitution with hydroponically germinating (h.g.) oat on plasma levels of cortisol and milk production. Germinated oat was used after 7 days of hydroponic growth. Control group (T) received only feed (fodder and oat integrated with complement feed). The other 2 groups were fed on diet containing different levels (1,5Kg - group A; 3Kg - group B) of hydroponically germinating oat. Goats showed a small interest in fresh feed during the trial period. The integration with hydroponically germinating oat in partial substitution of the traditional feed in the diet of goat did not significantly affect biochemical and haematological parameters

Growth performance and carcass characteristics of female turkeys as affected by feeding programs

ABSTRACT A trial was conducted to evaluate the effects of different feeding programs on growth performance and carcass characteristics of Nicholas Large White female turkeys. Three different feeding programs were considered for a 12-wk period: 1) 3 diets fed for 4 wk each (starter 24% CP, grower 20% CP, and finisher diet 16% CP), 2) 2 diets fed for 6 wk each (starter-grower 22% CP and grower-finisher diet 18% CP), and 3) no change of diet for 12 wk (starter-grower-finisher diet 20% CP). From 0 to 4 wk of age, birds were fed an ad libitum common starter diet. Each dietary treatment was replicated 3 times, and feed and water were provided ad libitum. Body weight and feed consumption were measured every 2 wk, whereas carcass characteristics were evaluated at 16 wk of age. Feed intake increased as the frequency of dietary changes decreased, and feed conversion was not different between programs 1 and 3. There were no significant differences in final BW among experimental groups. For a single feeding program, the proportion of neck, bone, and feet decreased, and a greater percentage of edible meat was registered as compared with the other 2 groups. Mean carcass, breast, and thigh weights of turkeys reared under multiple diets were not different compared with other groups. Positive correlations were noted between live weight and weight of carcass, breast, thigh, drumstick, wing, and abdominal fat of turkeys. Thus, a single cycle feeding regimen in Nicholas Large White female turkeys results in similar growth performance and carcass characteristics compared with other conventional feeding programs considered in the present study

Meat quality of Kuruma prawn (Marsupenaeus japonicus): preliminary evaluation

Among the peneids, Marsupenaeus japonicus, a cold-temperate species, carnivorous, is the mostly cultured prawn in Italy and in the Mediterranean Sea basin, thanks to the good adaptability to the temperature and salinity variations, to the good resistance to the manipulations (better resistance out of water), to its appreciate nourishing qualities and to the good growth rate (Lumare, 1998).Whereas the literature on cultured fish fillet is rich (Gjedrem, 1997; Lanari et al., 1999; Parisi et al., 2003), few are the information about the shrimp meat quality traits.Therefore, the present work aimed at typifying the variations of the meat quality characteristics in shrimps from semi-intensive (supplemented with an artificial diet) or extensive rearing systems

Use of sweet lupin (Lupinus albus L.) as alternative protein source in diets for podolian young bulls

AbstractThe Podolian bovine represents an important example of Italian rustic breed, since it is able to live under difficult environmental conditions and it takes advantage of sources that could not be otherwise used, producing meat and secondarily milk. The "Podolica" breed is diffused in the marginal areas of the south of Italy and it is especially reared in Lucania and also Apulia. It could be improved by means of a rearing management set up in agreement with the traditional systems, using the pastures and feeding schemes aimed to increase meat productions.This trial was carried out on sixteen podolian young bulls of about 9 months of age that were transferred from the pasture to the box and after that divided into two homogeneous groups of 8 subjects each. Then the young bulls had been fed ad libitum for about 180 days on straw and a complete feed containing either extruded soybean meal s.e. (group Soybean, S) or sweet lupine (Lupinus albus L., var. Multitalia) (group Lupine, L).The two different pel..

A Giant Gastric Hyperplastic Polyp in Non-Familial Juvenile Polyposis of the Stomach: A Case Report

Juvenile Polyposis Syndrome (JPS) is a rare genetic disorder characterized by juvenile polyps of the gastrointestinal tract, which may also occur in people with no family history of the disorder. It usually involves the colorectum and more rarely the stomach. Juvenile polyps can vary in size from a few millimeters to over 5cm, and, although they have microscopically specific characteristics, the distinction between them and inflammatory polyps is often difficult. Here we present a case of 41 year old woman with no family history of polyposis who underwent esophagogastroduodenoscopy (EGDS) because of anemia that showed a huge and extensive gastric lesion (10 cm in diameter) and other small polyps scattered through the stomach lumen and duodenum. The histology report revealed the big lesion and the polyps were hyperplastic polyps with infiltration of inflammatory cells. Due to clinical history and EGDS findings, the patient underwent a pylorus-preserving gastrectomy, and to define a final diagnosis genetic test was performed and showed mutation in the SMAD4 gene. Thus non-familial juvenile polyposis of the stomach was diagnosed. An original feature of the current case was the rare finding of huge hyperplastic gastric polyp in a woman with rare non-familial JPS of the stomach. In fact, to our best knowledge this is the first report describing a so giant gastric polyp in JPS of the stomach in an adult woman. Furthermore, our report suggests that it is noteworthy to consider JP as differential diagnosis in patients with non-familial polyposis, anemia or hypoproteinemia and polyps histologically diagnosed as hyperplastic and performing genetic testing for confirming diagnosis and helping in the timely and appropriate management

Epigallocatechin-3-gallate inhibits doxorubicin-induced inflammation on human ovarian tissue

Chemotherapy protocol can destroy the reproductive potential of young cancer patients. Doxorubicin (DOX) is a potent anthracycline commonly used in the treatment of numerous malignancies. The purpose of the study was to evaluate the ovarian toxicity of DOX via inflammation and the possible protective effect of the green tea polyphenol epigallocatechin-3-gallate (EGCG). Ovarian tissue of three patients was cultured with 1 \ub5g/ml DOX and/or 10 \ub5g/ml EGCG for 24 and 48 h. Levels of inflammatory factors were determined by quantitative Real-Time PCR, western blot, zimography, and multiplex bead-based immunoassay. Morphological evaluation, damaged follicle count and TUNEL assay were also performed. DOX influenced inflammatory responses by inducing a significant increase in the expression of pro-inflammatory cytokines, such as tumor necrosis factor-\u3b1 (TNF-\u3b1) and cyclooxigenase-2 (COX-2), of inflammatory interleukins (IL), such as interleukin-6 (IL-6) and interleukin-8 (IL-8), and the inflammatory proteins mediators metalloproteinase-2 and metalloproteinase-9 (MMP2 and MMP9). IL-8 secretion in the culture supernatants and MMP9 activity also significantly raised after DOX treatment. Moreover, a histological evaluation of the ovarian tissue showed morphological damage to follicles and stroma after DOX exposure. EGCG significantly reduced DOX-induced inflammatory responses and improved the preservation of follicles. DOX-induced inflammation could be responsible for the ovarian function impairment of chemotherapy. EGCG could have a protective role in reducing DOX-mediated inflammatory responses in human ovarian tissue
