Meat quality and caecal content characteristics of rabbit according to dietary content and botanical origin of starch
No full textThe research was carried out to study the influence of diets differing in contents and botanical origin of starch on fattening and slaughtering performance of rabbits. Four pelleted diets (LSM, LSW, HSM, HSW) were prepared according to a 2 x 2 factorial scheme: two starch contents (23 vs 28% DM) and two botanical origins (wheat vs maize). Before being slaughtered, 4 groups of 24 Hyla hybrid male rabbits from 59 to 90 days of age were fed ad libitum on the above diets. High starch diets decreased the feed intake (g 104.1 vs 111.5; P <
0.05 feed conversion (2.729 vs 3.071 and 3.801 vs 4.020 respectively for periods of 51-70 d and 71-90 d). In the first period (51-70 d), the liveweight gain showed an important trend (P = 0.16) for LS groups in comparison to HS groups (g 38.1 vs 36.3). An opposite trend was shown in the period of 71-90 d (g 28.9 vs 30.7 for groups HS and LS, respectively). In fact, liveweight at 90 d was similar (g 2755 vs 2757 for groups LS and HS, respectively) in the groups feeding different starch levels. The diets did not significantly affect slaughtering yields (hot carcass weight g 1705 vs 1714 and reference carcass weight g 1352 vs 1352 for groups LS and HS, respectively), chemical and nutritional characteristics of meat (crude protein 22.3% vs 22.2 and ether extract 3.0% vs 3.1 for groups LS and HS, respectively), and acidic composition of intramuscular fat. No significant differences were observed in the caecal content parameters (VFA mml/l 66.5 vs 66.4 for groups LS and HS, respectively), except for a lower caecal starch level (1.6% vs 2.0% DM; P <
0.05) in the group fed the diet with wheat and 23% of starch. No other botanical effect was significant

No full textDigestibility and ruminal fluid modifications in rams and buffaloes on ensiled maixe stalks and ful-fat soybeans flakes
No full textAuthors have estimated the voluntary intake of a diet with 10% of crude protein on dry matter (d.m.) composed of ensiled maize stalks and full-fat soybean flakes in buffaloes (15 months of age) and rams (2.5- 4 years of age).The d.m. voluntary intake resulted higher for buffaloes (67.8 vs 41.8). The Apparent Digestibility Coefficients were almost similar for the two species. The kind of diet influenced the ruminal fluid characteristics for each species

Vegetable and animal food sorts found in the gastric content of Sardinian Wild Boar (Sus scrofa meridionalis)
No full textAuthors report results emerging from gastric content analysis from n. 96 wild boars hunted in Sardinia isle, during the hunting tide (2001-2005), from November to January. Mean pH of the gastric content was 3.77 +/- 0.69. Mean total capacity (TC) of each stomach was 1702 +/- 680 g. Mean Stuff ratio (CW/TC) between the content weight (CW) and stomachs TC was 0.45. Food categories found in animal stomachs were: 19 categories of vegetal species (Allium spp., Arbutus unedo, Arisarum vulgare, Avena fatua, Avena sativa, Castanea sativa, Ceratonia siliqua, Chamaerops umilis, Cichorium intybus, Hordeum sativum, Juniperus oxycedrus, Myrtus communis, Olea europea, Pirus amygdaliformis, Pistacia lentiscus, Quercus spp., Rhamnus alaternus, Triticum durum, Zea mais); 11 categories of animal species (Agriotes lineatus, Apodemus sylvaticus dicrurus, Chalcides chalcides, Chalcides ocellatus tiligugu, Crematogaster scutellaris, Forficula auricularia, Helix aspersa, Lumbricus terrestris, Ovis aries, Podarcis tiliguerta tiliguerta, Scolopendra cingulata); three categories were identified in general terms (insects larvae, hairs of mammals, feathers of birds). Food categories found in the stomach contents of Sus scrofa meridionalis confirm observations by other researchers who report the prevalence of vegetables in spite of animal food sorts in the wild boar diet in Italian regions
