The effects of feeding regimen on carcass characteristics, meat colour and water-holding capacity of M. longissimus were studied in 24 female fallow deer (Dama dama). All animals were farm raised; twelve were grazed on pasture and twelve were fed barley and a small amount of hay prior to slaughter. The animals were slaughtered at two occasions (during the Southern Hemisphere spring); after 19 weeks of feeding (n=12; 6 grazing and 6 barley fed animals; group 1) and after 24 weeks of feeding (n=12; 6 grazing and 6 barley fed animals; group 2). The barley/hay-fed deer had significantly higher body condition scores and carcass weights than the pasture raised group. No difference in meat ultimate pH values between the treatment groups was recorded. The meat from the pasture raised deer had significantly longer colour display life after 2 and 3 weeks of refrigerated storage (+ 2.0 ºC) in vacuum bags. There was no difference in drip loss between the two treatment groups. However, significantly lower drip losses were found in meat from the animals in group 2 compared with the ones in group 1 (P ≤ 0.001). It was concluded that the feeding regimen of the animals is an important factor that contributes to the variation in quality of fresh chilled deer meat (venison), mainly the colour stability and display life of vacuum packaged meat.Abstract in Swedish / Sammanfattning: I denna undersökning ingick 24 dovhjortshindar (Dama dama) för att studera effekterna av olika typer av foder (bete och korn) på slaktkroppskvalitet samt färg och vattenhållande förmåga i köttet (M. longissimus). Alla djur var uppfödda på en hjortfarm, 12 betade gräs och 12 utfodrades med korn och en liten mängd hö före slakt. Djuren slaktades vid två olika tillfällen (under våren på det södra halvklotet); efter 19 veckors utfodring (n=12; 6 betesdjur och 6 kornfodrade djur; grupp 1) och efter 24 veckors utfodring (n=12; 6 betesdjur och 6 kornfodrade djur; grupp 2). De dovhjortar som utfodrats med korn och hö var i bättre kondition och hade högre slaktvikter jämfört med de djur som betat gräs. Ingen skillnad i köttets pH-värde mellan de två utfodringsgrupperna kunde dock påvisas. Köttet från de betande dovhjortarna hade bättre färgstabilitet efter lagring i 2 och 3 veckor (+ 2.0 ºC) i vakuumförpackning. Det fanns ingen skillnad mellan kött från betande och korn/hö-utfodrade djur i vattenhållande förmåga. Däremot hade kött från djur i grupp 2 (slaktade efter 24 veckors utfodring) bättre vattenhållande förmåga jämfört med grupp 1 (P ≤ 0.001). Vi kunde konstatera att de olika fodertyperna påverkade kvaliteten hos färskt kyllagrat kött, framförallt färgstabiliteten hos vakuumförpackat kött.

Twenty reindeer calves (age 10 months) were included in the study. They were all fed one of two different pelleted feed mixtures ad libitum for two months before slaughter. Ten calves were fed a control diet of conventional pellets (CPD) (Renfor Bas, Lantmännen, Holmsund, Sweden) and ten calves received pellets enriched with linseed cake (LPD). The reindeer were slaughtered according to standard procedure at Arvidsjaur Renslakt AB, a reindeer slaughter plant in Arvidsjaur, Sweden. At 1 day post mortem, both longissimus dorsi (LD) muscles from each carcass were excised. The left LD was used for sensory evaluation and the right LD for colour and water-holding capacity measurements. The right LD was cut in 4 pieces that were randomly allocated to storage times of 1 day, 1, 2, or 3 weeks at + 4 °C. Samples allocated for storage were vacuum packaged. Evaluation of meat colour was carried out after each of the four storage times while drip loss/purge was registered after 1, 2, and 3 weeks storage at + 4 °C. The left LD muscles were vacuum packaged, frozen at -20 °C and kept frozen until preparation for sensory evaluation. No significant differences were found in carcass quality (carcass weight, EUROP carcass conformation and fat scores), meat colour stability and water-holding capacity of LD samples when comparing the two treatment groups LPD and CPD. However, sensory panellists judged samples from LPD fed reindeer to have a tendency (not significant) to be more tender (P= 0.06) and juicy (P=0.07) than the meat samples from CPD fed reindeer. No flavour differences were found when comparing meat samples from the two treatment groups.

This study investigated the effects of Hibiscus (Hibiscus sabdariffa L.) seeds inclusion in diet of cattle. Fifty-five Sudan Baggara bulls were selected and divided into five treatment groups, and fed iso-caloric and iso-nitrogenous experimental diets where groundnut cake was the source of protein in the control diet (0% Hibiscus seeds), while in the other experimental diets, Hibiscus seeds replaced groundnut at a rate of: 25, 50, 75, and 100%. The crude protein was significantly lower in the 100% group than in the control group, whereas muscle fat content was significantly lower in the 25, 75, and 100% groups than in the control group. There were no significant differences between the tested groups for the carcass linear measurements, but there were so for the redness and yellowness color components of the fat, water-holding capacity, and cooking loss. In conclusion, the growth performance and meat quality attributes of the cattle were improved as the level of Hibiscus seeds increased up to 75%, without any adverse effect.

Mercury an important therapeutic substance in Tibetan Medicine undergoes complex “detoxification” prior to inclusion in multi-ingredient formulas. In an initial cross-sectional study, patients taking Tibetan Medicine for various conditions were evaluated for mercury toxicity. Two groups were identified: Group 1, patients taking “ Tsothel” the most important detoxified mercury preparation and Group 2, patients taking other mercury preparations or mercury free Tibetan Medicine. Atomic fluorescence spectrometry of Tibetan Medicine showed mercury consumption 130 µg/kg/day (Group 1) and 30 µg/kg/day (Group 2) ( P ≤ 0.001), levels above EPA (RfDs) suggested threshold (0.3 µg/kg /day) for oral chronic exposure. Mean duration of Tibetan Medicine treatment was 9 ± 17 months (range 3–116) (Group 1) and 5 ± 1.96 months (range 1–114) (Group 2) (NS) with cumulative days of mercury containing Tibetan Medicine, 764 days ± 1214 (range 135–7330) vs. 103 days ± 111 (range 0–426), respectively ( P ≤ 0.001). Comparison of treatment groups with healthy referents (Group 3) not taking Tibetan Medicine showed no significant differences in prevalence of 23 non-specific symptoms of mercury toxicity, abnormal neurological, cardiovascular and dental findings and no correlation with mercury exposure variables; consumption, cumulative treatment days, blood/ urine Hg. Liver and renal function tests in treatment groups were not significantly increased compared to referents, with mean urine Beta2 Microglobulin within the normal range and not significantly associated with Hg exposure variables after correcting for confounding variables. Neurocognitive testing showed no significant intergroup differences for Wechsler Memory Scale, Grooved Pegboard, Visual Retention, but Group1 scores were better for Mini-Mental, Brief Word Learning, Verbal Fluency after correcting for confounding variables. These results suggest mercury containing Tibetan Medicine does not have appreciable adverse effects and may exert a possible beneficial effect on neurocognitive function. Since evidence of mercury as a toxic heavy metal, however, is well known, further analysis of literature on mercury use in other Asian traditional systems is highly suggested prior to further studies.

ABSTRACT Background: In recent years, the incidence and geographic distribution of dengue fever have greatly increased. Dengue fever is an acute viral disease transmitted by mosquitoes and is characterized by fever, headache, muscle and joint pain, skin rash, nausea and vomiting. The Mosquito Nest Eradication Program (PSN) through 3M Plus needs to be carried out continuously throughout the year, especially in the rainy season through the movement of housewife who monitor larvae. This study aimed to determine the effect of the dengue fever vector eradication model through the housewife movement of larva monitoring in the efforts of dengue fever prevention in Mojolangu Village, Malang City. Subjects and Method: This was a quasi-experiment using 2 treatment groups and 1 control group conducted at Mojolangu village, Lowokwaru district, Malang. A sample of 90 respondents divided into three groups was selected by purposive sampling. The dependent variable was DHF Prevention Efforts (Larva Monitoring). The independent variables were Dengue Fever Vector Eradication Model. The data were collected by questionnaire and observation. The data was analyzed by Kruskal-Wallis. Results: After being given treatment in group 1 (educated by health workers) and group 2 (trained cadres) the ability increased to be very good by 83% and 53%. In group 3 (control) his ability improved by 37%. Group 1 has the most effective influence in increasing knowledge and skills. Then group 2 with a significance value of <0.001 (p <0.005). Conclusion: Housewife are a resource in Family Empowerment and Intervention models. The eradication of dengue vectors needs regular monitoring and monitoring so that self-awareness and independence from the family can increase so that the degree of health can be achieved optimally.

Peste des petits ruminants poses a major threat to the development of small ruminant production. The objective of this study was to determine the comparative efficacy of amantadine hydrochloride (HCl), oxytetracycline long acting (LA) and levamisole in West African dwarf (WAD) goats experimentally infected with PPR. In addition to the presence of the characteristic clinical signs, complement ELISA and haem agglutination inhibition (HI) tests were used to confirm PPR infection in the West African dwarf goats, then treatment was instituted in the different groups namely, group 1 which was treated with amantadine HCl orally, oxytetracycline LA intramuscularly (IM) and levamisole per os. Group 2 was treated with oxytetracycline LA IM and levamisole. Group 3 was treated with levamisole while group 4 served as untreated control. The physiological parameters namely rectal temperature, pulse rate and respiratory rates of the different groups were recorded. The mortality rates in the different treatment groups were also recorded. The respiratory rates of the WAD goats increased as the infection progressed, but the increase was not significant (P>0.05). The treatment helped reduce the respiratory rates in the treated WAD. The rectal temperatures of all the animals in the different treatment groups increased only slightly as the infection progressed and was not significant (P>0.05). The percentage mortalities were 0% in Group 1, 25% in the Group 2, 50% in the treated group 3 and highest (75%) in the untreated group respectively. In conclusion, incorporation of specific antiviral agents like amantadine hydrochloride in the treatment regimen with oxytetracycline and levamisole particularly during the early stages of the infection can reduce morbidity and mortality of the disease to the barest minimum.

AbstractLitter sanitation treatments and feed supplements that stimulate bird growth. The aim of this study was to analyse the effects of zeolite (z) and halloysite (h) in feed and rye straw litter on growth performance, meat quality in chickens. 500 males Ross 308 were allocated to 5 groups (10 replicates). Feed for groups 2–5 was supplemented with halloysite and zeolite (25:75). The content of aluminosilicates in the feed was different depending on the feeding phase: 0.5, 1, 1.5, or 2%. The following doses were used in litter: 2, 0.800 kg/m2 h; 3, 0.400 kg/m2 h and 0.400 kg/m2 z; 4, 0.800 kg/m2 z; 5, 0.200 kg/m2 h, and 0.600 kg/m2 z. Growth, and meat quality were analysed. Body weight and body weight gain were higher in groups 2–5 than in group 1, while feed intake was lower in groups 1 and 2 (p < 0.05). Body weight, the weight of carcass, and most of its elements were higher in the experimental groups (p < 0.05). Breast muscles from group 1 were characterised by better water-holding capacity and higher protein content, while those from 4 had higher content of collagen and water (p < 0.05). Breast muscles from group 3 were characterized by lower yellowness than in 2 (p < 0.05). Leg muscles from group 1 were characterized by lower redness than in 4 (p < 0.05). Water-holding capacity was better in group 3 and protein content was higher in 2 (p < 0.05). The content of fat in leg muscle was lower in all experimental groups compared to control (p < 0.05). This indicates the suitability of aluminosilicates in poultry management practice, with better growth and meat quality.

Abstract Basic carcass characteristics, the quality traits of meat and internal organs from 10 fallow deer bucks and 10 does aged from 31 to 32 months were investigated. No sex effects on the bled body weight, meat yield and carcass composition were found. A significantly higher weight of mesenteric and omental fat (by 0.44 kg) was found for does. The combined share of muscle and fat in the carcass parts ranged from 77.9 to 78.5%, and the share of bones from 21.5 to 22.1%. No sex effects were found for the pH and water holding capacity measurements. Venison from males was characterized by a significantly higher thermal drip value (P=0.043) and higher L* (P=0.026), a* (P=0.010) and b* (P=0.036) values compared to does. The extracted fat content was significantly higher for females compared to males (P=0.009). The chemical analysis of deer edible by-products indicated the highest level of protein for the liver (17%), and the highest level of dry matter and fat for the tongue (33-34% and 15-18%, respectively).

Abstract Background Failed back surgery syndrome (FBSS) is a common problem affecting 20–40% of cases undergoing spine surgeries. Spinal cord stimulation (SCS) has been shown to be an efficient and relatively safe treatment in managing many intractable chronic pain syndromes. Objectives This study compares the efficacy and safety of MR-compatible sensor driven-position adaptive SCS and conventional SCS in treating FBSS. Methods This is a retrospective case series of 120 consecutive FBSS patients who underwent SCS between February 2011 and March 2018. Pain levels, analgesic/opioid use, and sleep problems were assessed before and 3 months after the procedure in patients who received either conventional SCS (group 1; n = 62) or sensor-driven position adaptive SCS (group 2; n = 34). The degree of patient satisfaction, the change in the activities of daily living (ADLs) together with the rate of complications were compared in both treatment groups. Results The two treatment groups were homogenous at baseline. Patients in both groups improved significantly regarding pain, opioid consumption, sleep, and ADLs. The magnitude of improvement was statistically higher in group 2. An absolute reduction of 6 points on the VAS in patients who received position adaptive SCS vs a 3.3 point reduction in conventional SCS cases (p < 0.0001). Half of the patients in group 2 (n = 17) showed excellent satisfaction after the procedure versus 14.5% of cases in group 1 (n = 9). Conclusion SCS is an efficient and reliable treatment in FBSS. MR-compatible sensor driven-position adaptive SCS can be a more effective treatment in this patient group.
