ObjectivesThe objective of this study was to evaluate the effect of increased pork hot carcass weights on consumer visual acceptability and purchase intent ratings of top loin chops cut to various thicknesses in a price labeled versus unlabeled retail display scenario.Materials and MethodsPigs in this study were intentionally raised to reach heavier hot carcass weights when compared to industry standards. Pork loins (N = 200) were collected from 4 different hot carcass weight groups: a light weight (LT; less than 111.8 kg), medium-light weight (MLT; 111.8 to 119.0 kg), medium-heavy weight (MHVY; 119.1 to 124.4), and a heavy weight (HVY; 124.4 and greater). Loins were fabricated into 4 pairs of chops of specified thicknesses (1.27, 1.91, 2.54, and 3.18 cm) at Day 7, 8, or 9 postmortem. For each chop loineye area, length and width were measured. One chop from each specified thickness was then randomly assigned to be packaged with a label containing package price and weight information. The other paired chop was packaged without a label. Consumers (N = 393; 8 per panel) from the Manhattan, KS, area assessed chops from each weight group × thickness combination in both labeled and unlabeled scenarios. Chops were assessed on a 0 to 100 continuous line scale for desirability and purchase intent. Consumers were also able to indicate “yes” or “no” if the chop was either desirable and if they would purchase the chop.ResultsAs hot carcass weight increased, there was an increase in loineye area and chop length, with chops from HVY carcasses having greater (P < 0.05) loineye areas and lengths compared to all other weight treatments. For both appearance and purchase intent ratings, chops from HVY carcasses were given higher (P < 0.05) ratings compared to LT chops. Additionally, consumers gave greater (P < 0.05) appearance ratings to thicker cut chops. There was a hot carcass weight × chop thickness interaction (P < 0.05) for the percentage of consumers that indicated the chop was desirable overall. Regardless of hot carcass weight treatment, chops with a thickness of 1.27 cm had the lowest (P < 0.05) percentage of consumers indicate they were desirable overall. Within the LT and MLT weight treatments, chops with a thickness of 1.91 and 2.54 cm were similar (P > 0.05) with the greatest (P < 0.05) percentage of consumers who indicated they were desirable. Within the HVY weight treatment, chops with a thickness of 2.54 cm had the greatest (P < 0.05) percentage of consumers who indicated they were desirable. A greater (P < 0.05) percentage of consumers indicated “yes” they would purchase chops cut to a thickness of 2.54 cm compared to all other thicknesses. Additionally, there was a greater (P < 0.05) percentage of consumers who indicated they would purchase chops that were unlabeled compared to chops labeled with weight and pricing information.ConclusionThese results indicate that carcass weight and chop thickness can affect consumer preference and purchasing decisions. Thus, both should be considered by retailers when marketing fresh pork top loin chops.

Fifty Boran Bos indicus steers, all of which were born during the same months, were reared together on grass without supplementary feeding, until required for slaughter. Pre-determined randomly selected groups of these steers were slaughtered at 1½, 2½, 3½, 4, 5 and 5½ years of age. Carcass analyses were carried out and the changing relationship between the edible carcass components themselves and of their relationship to live and carcass weights during growth were investigated. It was observed that certain components maintained a near constant relationship to each other throughout growth. It was also noted that compensatory growth of light-weight weaners enabled them to be as productive, in terms of final carcass weight and composition at 3½ and 4 years, as heavy-weight weaners.

Abstract The present study used 48 lambs originating from three different locations in the Western U.S. (16 lambs per location; 8 ewes and 8 wethers per location). Each consisting of similar breed composition (Suffolk cross) that were selected to represent weight by age at harvest treatments: light weight carcasses at 5 mo. (LW5, 31.81 ± 1.88 kg), light weight carcasses at 12 mo. (LW12, 35.09 ± 4.45 kg), heavy weight carcasses at 12 mo. (HW12, 57.89 ± 4.70 kg) with different carcass weight compositions. Older heavy weight lambs (HW12) had greater (P ≤ 0.01) hot carcass weight, ribeye area, backfat and body wall thickness, and yield grade compared with light weight lamb carcasses (LW5 and LW12). The longissimus thoracis longissimus thoracis (LT) from older lamb carcasses (LW12 and HW12) had a greater (P ≤ 0.01) total lipid percentage compared with younger lamb carcasses (LW5). Across harvest weight and age treatments, wether carcasses had greater (P ≤ 0.05) total lipid percentage compared with ewe carcasses. Slice shear force values were greater (P ≤ 0.01) for both the LT and semimembranosus from older lambs (LW12 and HW12) compared with LW5 lambs, with no differences between ewes and wethers. Lamb flavor intensity was greater (P ≤ 0.05) for the LT of LW12 lambs and tended (P = 0.08) to be greater for HW12 lambs, compared with the LT from LW5 lambs. The off-flavor intensity of the LT was greater (P ≤ 0.01) for older lambs (LW12 and HW12) compared with LW5 lambs. Interestingly, the lamb flavor and off-flavor intensity scores of the ground shoulder exhibited a treatment × sex interaction. Lamb flavor intensity of LW12 lamb was greater (P ≤ 0.05) from ewes compared with wethers; whereas wethers had a greater (P ≤ 0.05) lamb flavor intensity compared with ewes for HW12 lambs, and LW12 ewe lambs had a greater (P ≤ 0.05) off-flavor intensity compared with all other treatment × sex treatment combinations. Overall, lambs in the present study possessed a mild lamb flavor, typically with greater lamb flavor and off-flavor intensities for older animals; while slice shear force and LT lipid percentage increased as animal age increased at the time of harvest.

Stocking Rates

Lamb meat production from an irrigated old ryegrass pasture farmlet is reported for the following conditions in successive years:- Year 1 and 2: Stocked at 18 ewes plus 5 ewe replacements/ha - dry summers Year 3: Same stocking rate as year 1 - moist summer Year 4: Stocking rate reduced to 15 ewes plus 4 replacements/ha - dry summer Year 5: Same stocking rate as year 4 - wet summer Mean carcass weight for all lambs in years l-5 was respectively 12.0, 12.4, 13.4, 12.0 and 14.2 kg; lamb meat production was respectively 241, 257, 252, 214 and 262 kg/ha. At high stocking rates, in the years with dry summers, early drafting of light weight lambs was necessary so that other lambs could achieve a target carcase weight of 13-16 kg. However ewe lambs did not reach that target. For two years with reduced stocking rate, dry summer weather in one of these years still precluded ewe lambs from reaching the target. In the other year with wet summer weather, production per lamb and per hectare was satisfactory. Further management means of increasing production of heavy weight lamb are discussed.

Abstract. This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.51-11.50 g), and heavy-weight (11.51-12.50 g). Based on storage period, eggs were divided into 5 groups as group 1 (0-3 days), group 2 (4-6 days), group 3 (7-9 days), group 4 (10-12 days), and group 5 (13-15 days). The influence of storage period on hatchability of fertile eggs and early, middle, and late period embryonic mortality rates was found significant (P<0.01). The effect of egg weight on fertility rate, hatchability of fertile eggs and early embryonic mortality was significant (P<0.05, P<0.01). The significant differences between storage period groups were observed in hatchability of fertile eggs. The differences between egg weight groups for fertility rate, hatchability of fertile eggs and early embryonic mortality was significantly higher in light weight group than the other egg weight groups. Results of this study concluded that a 12 day pre-incubation storage of hatching eggs of Japanese quails did not appreciably affect hatching parameters. Use of medium or heavy weight eggs for hatching may reduce early embryonic mortality rate.

Tomato juice has gained popularity in recent decades. However, little is known about tomato juice consumers in the United States. The goal of this research was to determine consumer attitudes towards current tomato juice offerings and willingness to pay for high flavor quality products. A sensory panel and a nation-wide survey were conducted to learn about consumer preference toward tomato juice consumption. A new “label”, including taste review ratings, was incorporated into a choice experiment to verify whether this information successfully assisted consumers in their purchase decisions. Both the sensory analysis and the consumer online survey showed a demand for tomato juice with better flavor. The results suggest that a premium quality tomato juice with fresh aroma notes and better taste made from a premium tomato will encourage consumer purchase intent. Consumers would be willing to pay up to 30% more if trusted taste review score information was provided.

Professionals involved in training programs for judokas should have access to evidence-based data on various characteristics of these athletes. In the current study, anthropometric (e.g., body height, body mass), physiological (e.g., power based on vertical jump height, maximal handgrip strength), and psychological (e.g., athletic coping skills) characteristics of judokas were examined. The judokas, aged 16-21, were classified into two groups: 30 light weight (males = 19, females = 11) and 27 heavy weight (males = 13, females = 14). Four MANCOVAs separated by sex were performed on the anthropometric, physiological, and psychological data. A discriminant analysis was also carried out. Results showed that heavy-weight males outscored their lighter peers on body height ( d = 1.88), arm span ( d = 1.88), and maximal handgrip strength. In the females, light-weight judokas outscored their heavier peers on jumping ability ( d = 1.02) and peak power bench press ( d = 1.20). Female heavy-weight judokas had greater body height ( d = 1.46), a longer arm span ( d = 1.35), and higher scores on maximal handgrip strength than light-weight judokas. The discriminant analysis revealed that 87.5% and 84.0% of the original grouped male and female judokas, respectively, were correctly classified. No differences in coping skills or self-regulation of learning between categories were observed. It is recommended that professionals involved in training programs may consider these differences in data when developing training programs for young judokas.
