Effects of a nutraceutical integration in mares and foals: preliminary results
No full textThe requirement for optimal nutrient concentrations is important both within the intestinal tract and at the cellular level. Nutrient requirements are sometimes expressed as the mean requirements for various classes of animals so that nutritionists sometimes include a margin of safety during times of stressful conditions. However, we need to keep in mind that life is a dynamic, complex process and consequently basic nutrient requirements are constantly shifting, especially within a growing animal or a female that is reproducing (Henry and Miles, 2000). Aim of this research was to evaluate, in trotting mares (during the last 3 months of pregnancy) and their foals (for their first 8 months of life), the effects of an oral supplementation (50g/d) with a nutraceutical product (Horse Care, Deavit ®) on serum osteocalcin concentration and on some serum mineral contents (Zn, Cu, P, Ca, and Mg), and alkaline phosphatase activity (ALP), both biomarkers of skeletal metabolism. These animals received only pasture and oats, living in a semi-range condition

No full textPhysical and chemical characteristics of doneky meat from Martina Franca breed
Full text linkThe rheological and chemical characteristics of meat obtained from 12 Martina Franca donkey males, slaughtered at 14 months of age and a mean final body weight of 169 kg were determined. Meat samples were taken four days post mortem from muscles Longissimus thoracis et lumborum and Biceps femoris, colorimetric parameters were measured to determine L* (lightness), a* redness), b* (yellowness) and chroma. The Longissimus was significantly lighter (P < 0.05) compared to the Biceps femoris, with L* indexes of 35.86 and 31.34, respectively. Fatty acid composition of the intramuscular fat showed a high content of polyunsaturated fatty acids (PUFAs) in both muscles, respectively 25.16 g/100 g total fatty acids in the Longissimus and 24.97 g/100 g total fatty acids in the Biceps femoris; oleic acid and palmitic acid were the two most abundant fatty acids in both muscles. The percentages of essential amino acids were higher in both muscles compared with the total amino acid content, respectively 52.88% in the Longissimus, and 51.26% in the Biceps femoris. The high level of unsaturation of the intramuscular fat resulted in a high ratio of unsaturated to saturated fat, and the total amount of essential amino acids, exceeding 50% of the total amino acids showed that donkey meat from a health point of view is a good alternative to traditional red meats
Quality of donkey meat and carcass characteristics
No full textA study based on 15 entire donkey males was carried out to evaluate carcass quality and nutritional characteristics of meat obtained by these animals slaughtered at 15 months of age and a mean final body
weight of 181 kg. The meat had a low (2.02 g/100 g) fat content, an appreciable (22.8 g/100 g) protein
content, and cholesterol content was 68.7 mg/100 g. Glycogen was also determined (0.45 g/100 g) within
12 h of sampling. Potassium was the mineral with the highest content (343 mg/100 g), followed by phosphorus (212 mg/100 g), sodium (52 mg/100 g) and magnesium (24 mg/100 g). Donkey meat obtained
from young animals can be considered a good alternative to other red meats and not only for the production
salami, or other fermented meat products
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
