Investigations were carried out on 60 suckling lambs (24 males and 36 female lambs) - R2 generation obtained by crossing Pirot Pramenka with W?rttemberg rams, divided into 3 groups. At the beginning of the trial lambs were 30 days old with average body mass of 15 kg. Animals were fed ad libitum alfalfa hay and iso-protein mixtures (16% total protein) with different energy content. Energy value of used mixtures was 7.29 (I), 7.71 (II) and 7.94 MJ NEM (III). Trial lasted 60 days. Following production parameters were monitored: body mass, average daily gain, feed and nutrient consumption and conversion, depending on the applied feeding treatment. Statistical processing of obtained data was carried out on PC, using variance analysis. Final body masses of lambs (age of 90 days) were: 29.81 kg (I), 31.19kg (II) and 29.86 kg (III). Average daily gain for entire fattening period according to treatments I: II: III was 0.280kg: 0.303kg: 0.277kg. Values of DM conversion (kg/kg) for trial groups I:II:III were 2.68: 2.58: 2.93. Utilization of energy (MJ/kg) in average was 19.45: 18.98: 21.64, whereas the conversion of total protein (g/kg) according to the same order of treatments was 481: 451: 514. Performed research has shown that certain advantage can be attributed to lambs fed fodder mixture II (16% of total protein and 7.71 MJ NME), considering that they have realized the highest gain and the lowest use of feed and nutrients as well as energy.

Research was carried out on experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun. Trial included 60 lambs - crosses of F1 generation of Pirot Pramenka x W?rttemberg x Ile de France weaned at the age of 60 days. Nutrition treatment included study of three concentrated mixtures which were different in protein source (sunflower, soy bean and fish meal), i.e. share of proteins non-degradable at the level of reticulo-rumen: 43 (I) : 51 (II) : 58%(III). The effect of stated treatment in intensive fattening of lambs was monitored through production parameters. Obtained data was processed using standard statistical analysis. Average body mass of lambs at the beginning of trial, in treatments I: II: III was: 18,08: 18,12: 18,17 kg. After fattening of 75 days, final body mass of lambs in analogous treatments was: 30,78 (I) 33,52 (II) 35,17 kg (III) and average daily gain: 0,169: 0,205 : 0,227 kg. Per kilogram of realized gain of lambs, in analogous treatments, the following was consumed: 4,54 : 3,71 : 3,30 kg of dry matter of diet; energy: 33,77: 29,37 : 26,25 MJ; total proteins: 732 : 596 : 549 g. Research demonstrated that protein source in concentrate mixtures used in nutrition of fattening lambs (i.e. share of nondegradable protein in total proteins)had significant effect on production parameters, and the best performance was registered in lambs on treatment with fish meal (share of NP was 58%).

The objective of this study was to evaluate the effects of frequency of concentrate supplementation on the daytime feeding behavior (grazing, rumination, drinking, and idle times), production performance, and economic viability of grazing cattle in the rainy season. A total of 120 uncastrated Nellore animals with an average body weight (BW) of 382.5 ± 32.2 kg were allocated to palisadegrass (Brachiaria brizantha) paddocks for the experiment. We evaluated supplements provided in the amount of 2.0 kg/animal, supplied three times weekly (3tw) or daily (7X). Animals supplemented 3X (5.46%) spent more time (%) drinking water than those supplemented 7X (3.72%). Grazing time and animal performance were not influenced by the frequency of supplementation. Average daily gain was 1.00 and 1.02 kg/animal for the groups under 3X and 7X, respectively. Expenditures on transportation and labor are lower (43%) when animals are supplemented 3X. Supplementation provided three times per week does not affect the grazing time or the performance of beef cattle in the rainy season, but rather implies an expressive reduction of expenditures on labor and distribution of supplements.

The rapid increase in human population leads to increased demand for animal protein. On the other hand, the deficit of protein feeds in the market and rising costs are the most significant obstacles facing animal production. Therefore, most researches have focused on improving the status and utilization of different protein sources in order to reduce costs and maintain optimum performance of animals. The results of our study showed that lambs of MIS population, of average body weight of 18.0 kg, fed diets with different protein sources: sunflower meal, soybean meal, fish meal, realized average daily gain: 0.169, 0.205 and 0.227 kg, respectively. Conversion of dry matter in analogue treatments was: 4.54, 3.71 and 3.30 (kg/kg of gain) and total protein (g/kg): 732, 596 and 549, respectively. It is evident that the fish meal as a protein source improves the growth and utilization of food in lambs. However, given that the European Commission has banned the use of fish meal in diets for animal nutrition, nutritionists? imperative is to investigate the possibility of using "unconventional" sources of protein (peas, beans, lupins) in diets for ruminant nutrition. The aim of this study was to compare the effects of different sources of protein in diets on production performance of ruminants.

Limb Dominance

To test the null hypothesis that limb dominance (laterality) and side of complaint are not associated in a diverse population, nearly 400 patients (40% male, 60% female) of varying age and body size from three South Florida podiatric medical teaching facilities were surveyed in 1995-1996. Radiographs of feet were available for 15% of the patients, and the metatarsus adductus angle was measured on each x-ray. The typical patient was a women (median age, 49 years) of average body weight and average body-mass index. No statistical association was found between laterality and side of complaint in the broader sample, although a significant association did appear in the subsample of patients with bilateral x-rays. The prevalence of metatarsus adductus deformity (metatarsus adductus angle > 15 degrees) among patients with x-rays was 62%. No sex-specific, age-specific, or body size-specific associations were found between handedness and metatarsus adductus deformity.

This work aimed to determine the nutrient intake and quantitative aspects of sheep carcass from three different genetic groups. Eighteen animals with initial average body weight of 20.1kg were used in a completely randomized design, in a factorial 3x2 scheme (three different crossbreeds - 6 F1Dorper x non defined breed, 6 F1Somalis x non defined breed and 6 F1Santa Inês x non defined breed versus two diets). The diets fed to the animals were formulated with or without cashew nuts. The inclusion of cashew nut meal in the diet influenced nutrient intake. Differences of intake among the animal groups were observed as higher intake for F1Dorper x non defined breed (NDB), followed by F1Somalis x NDB and for F1Santa Inês x NDB. However, the control diet produced no difference among these genotypes. The average daily gain was lower for both crossbreeds when cashew nut meal was added in the diets. The evaluated crossbreeds and diets did not affect the feed:gain ratio. The carcasses analyses showed that the inclusion of cashew nut meal in the diets reduced the cold carcass weight and the rib weight. The addition of cashew nut meal in the diets for lambs reduces food intake and carcass yield. The crossbreed F1Dorper x NDB presented the higher rate of average daily gain.

Abstract Introduction. Doing asymmetric sports when one suffers from body asymmetry may cause body posture disorders. The aim of the study was to assess the spinal and shoulder complex mobility of professionally trained volleyball athletes compared to that of their peers who do not practise any sports. Material and methods. The study involved 60 participants divided into two groups. Group 1 consisted of 30 girls aged 14 years. The average height in the group was 176.37 ± 6.29 cm, and the average body mass was 64.53 ± 7.12 kg. Group 2 consisted of 30 girls aged 15.6 ± 1.12 years who did not practise any sports. The average body height in this group was 159.37 ± 3.33 cm, and the average body mass was 51.83 ± 4.03 kg. The dominant limb was defined on the basis of lateralization. The spinal range of motion was measured by means of a Saunders digital inclinometer, and the shoulder complex range of motion was examined using the goniometric method. Means and standard deviations were calculated, and Student’s t-test was applied in order to determine the differences between the two groups. Results. The differences in the values obtained in the two groups for the spinal range of motion in the sagittal plane were statistically significant only for the range of lumbar spine bending and extension. It was found that group 1 had a higher range of spine mobility in the frontal and transverse planes, and the differences were statistically significant in all the assessed ranges towards the dominant limb. An analysis of the shoulder girdle range of motion in the groups revealed that the differences were also statistically significant in all of the examined ranges. Conclusion. Professional volleyball practice can cause an increase in spine flexibility in most of its ranges, and the shoulder girdle range of motion in female volleyball players can exceed population norms, especially for the upper dominant limb.

Nocturnal geckos can walk on level ground more economically than diurnal lizards. One hypothesis for why nocturnal geckos have a low cost of locomotion is that they can perform mechanical work during locomotion more efficiently than other lizards. To test this hypothesis, we compared the efficiency of the nocturnal gecko Coleonyx variegatus (average body mass 4.2 g) and the diurnal skink Eumeces skiltonianus (average body mass 4.8 g) when they performed vertical work during uphill locomotion. We measured the rate of oxygen consumption when each species walked on the level and up a 50 slope over a range of speeds. For Coleonyx variegatus, the energetic cost of traveling a unit distance (the minimum cost of transport, Cmin) increased from 1.5 to 2.7 ml O2 kg-1 m-1 between level and uphill locomotion. For Eumeces skiltonianus, Cmin increased from 2.5 to 4.7 ml O2 kg-1 m-1 between level and uphill locomotion. By taking the difference between Cmin for level and uphill locomotion, we found that the efficiency of performing vertical work during locomotion was 37 % for Coleonyx variegatus and 19 % for Eumeces skiltonianus. The similarity between the 1.9-fold difference in vertical efficiency and the 1.7-fold difference in the cost of transport on level ground is consistent with the hypothesis that nocturnal geckos have a lower cost of locomotion than other lizards because they can perform mechanical work during locomotion more efficiently.

During late spring of 2007 and 2015, we observed unusually high mortality of Common Eiders (Somateria mollissima) on Christiansø in the Baltic Proper. The number of dead birds (2007: 125; 2015: 110) composed 5–10% of the total colony. In 2015, we collected 15 (12 adult females, three subadult males) of the 110 recently deceased Common Eiders for detailed autopsy. The average body mass of the females was 1,040 g (920–1,160 g) which is ca 60% lower than what can be expected of healthy females during wintertime. Similarly, for the subadult males the average body mass of 1,203 g (1,070–1,300 g) comprised only 45% of what can be expected for healthy subadult males during winter. All 15 birds were thus severely emaciated and cachexic with general atrophy of muscles and internal organs. Hunger oedema, distended gall bladder, empty stomach, empty and dilated intestines and dilated cardiomyopathy were observed as well. In addition, all 15 Common Eiders were infected with high loads of the acanthocephalan parasite Polymorphus minutus. No gross morphological changes suggested toxicological, bacteriological or viral causes to the mortality. Taken together, our autopsy suggested starvation leading to secondary metabolic catabolism and eventually congestive heart failure. Five birds that were examined in 2007 showed the same symptoms. We suspect that the introduction of suboptimal feeding conditions in combination with a high parasite load over the last decade synergistically caused high physiological stress leading to population level effects manifested as high mortality.

The researches followed the effects of powderYEA-SACC 1026 probiotic on some production and consumption indices in chicken broilers. The researches were effected on 75 meat chickens of Ross-308 hybrid, which were grouped in three lots of 25 capita/lot during 42 days. In the lot L1(E), for 42 days, in the mixed fodder was added YEA-SACC 1026 probiotic in proportion of 0.1% in breeding phase I (1-14 days), of 0.1% in phase II (15-35 days) and 0.1% in phase III (36-42 days). In the lot L2(E), for 42 days, in the mixed fodder was added YEA-SACC 1026 probiotic in proportion of 0.25% in breeding phase I (1-14 days), of 0.25% in phase II (15-35 days) and 0.25% in phase III (36-42 days). The chickens of all lots were weighted at the beginning of experiment and after that weekly being calculated the average body weight, average daily gain, fodder intake and fodder conversion index. The use of y YEA-SACC 1026 probiotic in lot L1(E) determined an increase of body weight with 16.26%, of average daily gain with 15.55% and the fodder conversion index was reduced with 29.16% given to Control Lot L(M). On the second place was situated the lot L2(E), in witch was administered 0.25% of YEA-SACC 1026 probiotic, with an increase of body weight of 8.32%, of average daily gain with 7.54% and the fodder conversion index was reduced with 21.78% given to Control Lot L(M). These superior results, registered in meat chickens from lot L1(E) YEA-SACC 1026 probiotic 0.1% and lot L2(E) YEA-SACC 1026 probiotic 0.25%, confirm the favourable influence of this probiotic on chicken broilers’ performances.
