Nutrutional quality of meats from young fallow deer (Dama dama) of different ages
Twelve male fallow deer (Dama Dama) were slaughtered at 3, 6 and 12
months of age. The productive performances of the animals and the most si
gnificant quantitative and qualitative traits on carcasses and meats were asses
sed. Four animals were slaughtered at 90 days of age, the others, allotted to
two groups of four animals each, at 6 and 12 months, respectively. Ali the
animals were kept in paddocks where, besides pasture, they received a supple
mentary feed 500 g/heaclld on the average. From the data available it emer
ges that the 6-month-old fallow deer as compared to the 12-month-old
bucks, present better gains and a reduced chilling loss of the carcass, the cuts
of which into leg and loin and their lean fractions do not differ as to age.
Moreover, the meats of these animals always in comparison with the 12
month-old bucks do not differ for "a" redness, "L" lightness as well as chemi
cal composition. The meats are also less tough, less resistant and with reduced
quantities of free water. At last, the fat extracted from the meat of 6-month
old fallow deer vs the older ones, in spite of a greater content in unsaturated,
polyunsaturated and monounsaturated fatty acids, the differences of which
have no statistical value, is even richer in 0)6 and poorer in 0)3 fatty acids
Quality of the meat of wild and raised wild boar
In order to study the meat quality of wild boars and in particolar their fatty acid composition 8 carcasses of male wild boars have been analized, 4 of which come from hunting territorle and the remaining 4 reared in outdoor pens, till 9 months of age. Every right half part, of each carcass, has been divided into commercial cuts and from each of them a sample of I "Longissimus dorsi," has been taken, on which chemical and physical analises have been carried out. On the fat extracted from this muscle, tha fatty acid composition has been determined. Our results show that the cooked meat of wild wild boars have the highest (P < 0,05) presence of omega 3 (2,28% vs 1,13%) and, even if without significance, the best ratio omega 6/omega 3 (7,07 vs 10,04) and the highest percentage presence of omega 6 (15,63% vs 10,48%). Moreover the cooked meat of wild animals has been showed the best (P < 0,05) TI (0,96 vs 1,39), and the best ratio unsaturated/saturated (1,76 vs 1,32); saturated/polyunsaturated (2,13 vs 4,05) and PCL/PCE (1,72 vs 1,25), even if they are not significant

Chemical and acidic characteristics of meat of Podolian bulls slaughtered at different ages
Chemical and fatty acid characteristics of meat of Podolian bulls slaughtered at different ages
Podolian cattle represents one of the most important native Italian breed. This breed was once
dolian
reared in many different Italian regions, whereas in recent years a dramatic reduction of the number
of head has relegated this breed to some marginal areas of southern Italy. For meat production, calves
are dam-reared on pasture for about 8-10 months and, subsequently they are fed a finishing diet in
loose house conditions with external paddock. They usually are slaughtered from 14 to 18 months of
age. The aim of this study was to evaluate the chemical and the fatty acid composition of sample cuts
of Podolian bulls slaughtered at different ages; even if breed, age and sex related to differences in the
fatty acid composition of beef cattle have been widely demonstrated (Einchhorn et al., 1986; Huerta-
Leidenz et al., 1996; Malau-Aduli et al., 2000), few data are available on Podolian cattle. This trial was
carried out on 12 Podolian steers, from the same farm in the Basilicata region. The subjects, at the
age of about 10 months, were moved to a stall for fattening and divided into 2 homogeneous groups of
6 animals each. During the trial period, the animal were fed ad libitum with hard wheat straw and a
complete pellet feed, containing barley, oats, field beans, and a vitamin-mineral integrator. The steers
were slaughtered at the age of 14 months (A group) and 18 months (B group), according to veterinary
police rules. The chemical composition of raw Longissimus lumborum (Ll) of the B group presented a
more higher incidence of protein (22.25% vs. 21.34%; P<0.01) and a lower value of moisture (72.29% vs.
73.92%; P<0.01), data also found in the works of Cifuni et al. (2004) and Marino et al. (2006). No sig-
nificant differences emerged in fat percentage between the two ages. The fatty acid composition of the
fat extracted from the raw Ll was not very different into the two groups. The only significant difference
was showed in the ω6/ω3 ratio, the older animals presented a higher value (7.472 vs. 5.270; P<0.05),
due to the higher percentage of ω6 (2.48% vs. 2.25%) and the lower percentage of ω3 (0.35% vs. 0.47%),
into their fat (Carnovale and Nicoli, 2000; Lengyel et al., 2003). The same results were found in the tri-
als carried out by Enser et al. (1999), Elmore et al. (2004) and Descalzo et al. (2005), where the increase
of percentage of ω6 and of the value ω6/ω3 are due to the cereal-based diet used to feed animals. The
group B showed no increase in the percentage of intramuscular fat during the fattening period from
14 to 18 month and to maintain the fatty acid composition very similar to the group A
