Retail Cuts

Carcass data were obtained for 258 lambs [hot carcass weight 16.0-28.7 kg, fat depth at the GR site (12th rib) 5-23 mm]. The sample included ewes, wethers, and cryptorchids (86 of each). Of these, 130 carcasses (42 ewes, 45 wethers, 43 cryptorchids) were prepared as boneless, heavily trimmed, 'trim lamb' cuts (i.e. a range of cuts promoted by the Australian Meat and Livestock Corporation). The remaining 128 carcasses (44 ewes, 41 wethers, 43 cryptorchids) were prepared as traditional, trimmed, bone-in cuts. Comparison of fat depth values before and after trimming over the loin at the 12th rib showed that the fat depth was reduced to a maximum of 4.0 mm. Models were developed based on hot carcass weight and GR measurement to enable estimation of the weight of each cut and carcass component (e.g. fat waste). The amount of variation of the components explained by the independent variables hot carcass weight and GR (R2 values) ranged from 0.46 to 0.93. The time to prepare trim cuts from 115 carcasses and traditional cuts from 121 carcasses was measured. Depending on the combination of trim cuts prepared, it took a butcher, on average, 9.6-13.1 min longer to prepare these cuts from each carcass than to prepare traditional cuts, without considering the weight and fatness of the carcass. Regression analysis showed that preparation time increased as carcasses become either heavier or fatter, irrespective of the type of cuts being prepared. When differences in carcass type were accounted for, the difference in preparation time between trim lamb and traditional cuts decreased. The effect of fatness on preparation time was such that for every 5-mm increase in GR (equal to a fatscore), an additional 1-2 min was required to prepare both types of cuts. When the hindleg was broken down into trim cuts, the round cut from the cryptorchid carcasses was significantly heavier than from the ewe and wether carcasses. The neck and shank from cryptorchid carcasses were heavier (P<0.05) than from ewe and wether carcasses. Ewe and wether carcasses produced heavier (P<0.05) ribloin cuts (7- or 8-rib cut) than cryptorchid carcasses. There was a variable effect of sex on the cuts from the loin, with cryptorchid carcasses producing heavier (P<0.05) midloins but lighter (P<0.05) boneless loins than the ewe carcasses. There was no difference (P>0.05) between ewe and cryptorchid carcasses for the weight of the eye of loin, and there was no sex effect on the weight of the chump. Cryptorchid carcasses produced more (P<0.05) sausage trim than wethers, which produced more than ewes, this being a reflection of a decreasing proportion of breast and flap. Regardless of cutting method, cryptorchid carcasses produced significantly more saleable components than wether and ewe carcasses, which were similar. For a carcass of cold weight 20.2 kg and GR 12.5 mm prepared into one of the combination of trim cuts, the proportion of saleable meat is estimated to be 75.9, 73.4, and 73.7% for cryptorchids, wethers, and ewes.

The objective was to evaluate the effect of the substitution (0, 33, 66 and 100%) of corn by cassava wastewater dregs on carcass characteristics and non-carcass components of crossbred Santa Inês lambs. Forty male sheep, uncastrated with an average initial body weight of 20 ± 1.87 kg and five months of age, were used. These were housed in individual pens in a randomized block design with four treatments and ten repetitions and slaughtered after 70 days of confinement. Quadratic effect (P &lt; 0.05) was observed for the empty body weight (EBW), hot carcass weight (HCW) and cold carcass weight (CCW) and carcass compactness index (CCI), with maximum points of 36.14, 19.45, 20.20 and 0.31 kg cm-1 for the replacement level of corn for cassava wastewater dregs, 50.0, 53.84, 54.04 and 45.45% respectively. There was also an effect (P &lt; 0.05) on the weights of the rumen and “Buchada”, with maximum points of 0.909 and 6.25 kg per replacement level, 49.11 and 51.29% respectively. As for retail cuts, only the efficiency of the leg was altered (P &lt; 0.05), having a linear increase while the other variables were not affected. Cassava wastewater dregs can be used in full as an alternative food in the diet of feedlot lambs without harming the main carcass characteristics and non-carcass components.

The Difference

Under commercial conditions in Australia, lambs are often dehydrated at slaughter despite access to water at the abattoir. Dehydration results in reduced fluid content of meat, which causes liveweight and carcass weight loss. Two experiments evaluated hydration status and carcass characteristics in lambs fed increased levels of sodium chloride (salt) and/or betaine before slaughter. Both experiments were 2 × 2 factorial designs with two levels of salt added [0 and 50 g/kg dry matter (DM)] and two levels of betaine added (0 and 6.7 g/kg DM) to the diets. The treatment diets were introduced to sheep over a 7–8-day period and then fed at 1.5 kg/day for the following 7 days. In experiment 1, 96 Poll Dorset–Merino cross wether lambs (45.9 ± 0.17 kg) were fed in individual pens and in experiment 2, 204 Merino wether lambs (43.1 ± 0.35 kg) were fed in group pens. In the first experiment, water and feed were withheld from the end of the treatment feeding period until slaughter 48 h later. In the second experiment, feed and water were withheld for the first 24 h after treatment but water was available for the next 24 h immediately before slaughter. In both experiments, consumption of the high salt diet decreased urine specific gravity and osmolarity at the end of the feeding period and after 24 h without access to water. This indicates an improved hydration status at this time. However, the difference in hydration status related to feeding salt declined during the 48-h lairage period and there were no significant differences in hot carcass weight or muscle DM among groups at slaughter. It could be concluded from this result that the addition of salt has little commercial value; however, this may not be the case. The lambs in experiment 2 did not behave according to industry expectations. They all drank water in the last 24 h in lairage and none of the groups showed severe dehydration. Further research is justified to determine if the lambs fed the diets with no added salt drunk in lairage as a learned response from the lambs fed salt and, if so, whether this can be developed into a commercial strategy. Feeding betaine did not result in any changes in hydration status or carcass characteristics.

The Difference

Slaughter and carcass data were obtained from 60 cattalo that averaged 1/7 bison–6/7 domestic (27 bulls, 33 heifers), 19 Hereford (11 bulls, 8 heifers), and 17 1/4 Brahman–3/4 Hereford (12 bulls, 5 heifers) yearlings. At a constant age, 1/4 Brahman and Hereford exceeded cattalo in growth rate, i.e. slaughter weights were: 1/4 Brahman 381 ± 10 kg, Hereford 376 ± 8 kg, and cattalo 353 ±5 kg. At a constant 24-h cold carcass weight, cattalo exceeded Hereford in carcass length (2.3%). Breed groups did not differ in mean fat thickness over, or area of, the longissimus dorsi, dressing percent, or transit shrink. At a constant carcass weight, the weight of the loin section was similar in all breed groups, but Hereford exceeded cattalo in round weight (2.6%), cattalo surpassed 1/4 Brahman in rib weight (4.3%), and 1/4 Brahman exceeded Hereford in shoulder weight (3.2%). Bison and cattalo were reported to have heavier front than rear quarters. This study suggests that the cattalo were not heavier in the shoulder but were lighter in the round than the Hereford and that the difference basically was in the weight of the hind shank.

ABSTRACT Objective To analyze cutting capacity, preparation time, and occurrence of apical deviation, after instrumentation of curved canals with reciprocating Primary WaveOne ® and R25 Reciproc ® systems. Methods Twenty simulated canals with 35° bends were randomly assigned to the Primary WaveOne ® or R25 Reciproc ® . The preparations were made by a single operator. The cutting capacity was assessed by the difference in weight (on an analytical balance) of the canals before and after preparation. The time needed for the preparation was analyzed. The canals were filled with India ink and photographed on a platform before and after the preparation to analyze the apical deviation to a 1 mm length. The images were superimposed in Photoshop ® and the measurement was performed with the ruler tool. Statistical analysis was performed using Student’s t-test. The level of significance was set at 5%. Results The WaveOne ® Primary system was more effective (in terms of cutting capacity) but had a longer preparation time than the R25 Reciproc ® instrument. Apical deviation was the only variable that did not significantly differ between the two systems. Conclusion The WaveOne ® Primary had a higher cutting capacity than the R25 Reciproc ® . Both systems maintained the original canal path. The preparation time was shorter for the R25 Reciproc ® than the WaveOne ® Primary system.

The Capital Market

The existence of the capital market makes the company has tools to measure the performance and financial condition of the company. If the company's financial condition is good, then the market will respond positively through an increase in stock prices. With the rise in stock prices in the capital market, more and more investors will invest in investments. In general, investors will invest if the investment can get the maximum return with certain risks. The stock valuation in fundamental analysis is often used by market analysis to determine the capital investment for the share Price Earning Ratio (PER), Market to Ratia Book, and Dividend Yield. In this research, the data used is secondary data. Samples are taken by systematic samples. This study uses regression analysis, Stock Return as the dependent variable and PER, MTB, DY and NI as independent variables. The results of the research conducted in the regression analysis were 32.6% in 2010, 25.5% in 2011, 26.3% in 2012 and 20.8% in 2010-2012. PER variables, MTB, DY, and NI for Returning Shares. This means that PER, MTB, DY, and NI simultaneously affect Stock Return. MTB positive effect on Stock Return, while PER, DY and NI negative effect on Stock Return, and four independent variables, MTB variable is the most dominant variable effect on Stock Return

Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass measurements were studied. Twenty-eight non-castrated sheep averaging 7 ± 1.4 months of age with an initial weight of 19.5 ± 4.3 kg were slaughtered after 70 days of confinement. There was a linear decline (P ≤ 0.05) in slaughter body weight, empty body weight, hot and cold carcass weight and longissimus muscle area (LMA) as the percentage of dietary CBH increased. A linear decrease (P≤0.05) of the weights of all retail cuts and a quadratic effect (minimum yield of 9.84% with the replacement of 56.9%) of the neck yield were also detected as the percentage of CBH increased. No treatment effects (P > 0.05) on the yield of the other cuts were observed, but there was a linear decline (P ≤ 0.05) in the perimeters of the thorax, leg and rump and the carcass compactness index. Replacing Tifton 85 hay with CBH in sheep diets is not recommended because it decreases the slaughter body weight, cold and hot carcass weight, retail cut weights and morphometric measurements.

According to Basic Health Research 2013 states that the age group less than 12 years ie age 5-9 years 28.9% suffered dental caries. The aim of this study is to analyze the effectiveness of animated movies and non- animated movies in improving children’s knowledge and behavior concerning dental health. This study was designed based on quasi experimental design. The samples of this study were the students of Class 3A and Class 3B SDN 03 Kepanjen consisting of 63 students. The independent variables of this study were animated movie and non-animated movie concerning dental health while the dependent variables were children’s knowledge and behavior. The collected data were analyzed using Mann Whitney test. The findings of this study show that the respondents are aged between 8 and 10 years old. There is difference in terms of knowledge before and after the students received intervention through animated movie and non-animated movie. Animated movie seems to be more effective in improving the respondents’ knowledge to maintain dental health than non-animated movie as indicated by the average score for animated movie intervention is higher than non-animated movie intervention.

Factor Type

Rapid thermal annealing (RTA) of ion-implanted Si is important for device fabrication. The defect structures of 2.5, 4.0, and 6.0 MeV As-implanted silicon irradiated to fluences of 2E14, 4E14, and 6E14, respectively, have been analyzed by electron diffraction both before and after RTA at 1100°C for 10 seconds. At such high fluences and energies the implanted As ions change the Si from crystalline to amorphous. Three distinct amorphous regions emerge due to the three implantation energies used (Fig. 1). The amorphous regions are separated from each other by crystalline Si (marked L1, L2, and L3 in Fig. 1) which contains a high concentration of small defect clusters. The small defect clusters were similar to what had been determined earlier as being amorphous zones since their contrast was principally of the structure-factor type that arises due to the difference in extinction distance between the matrix and damage regions.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
