Abstract Improvements in growth and carcass conformation through terminal sire crossbreeding systems may improve lamb value in a pasture-based system. Therefore, the aim of this study was to replicate the previous model of this experiment and compare the effects of different terminal sires on parasitism, growth, composition and marketability of grazing lambs and lambs at weaning. Suffolk SU (n = 2) and Texel TX (n = 3) sires were mated to commercial ewes at the WVU Organic Farm. April-born lambs were managed as one group until weaning in mid-June. One group containing TX (n = 28) and SU (n = 22) was sold at weaning, the other group was sorted into 3 replicates per sire breed. Lambs were rotationally grazed for 62-d with paddock movements every 10-d. Lambs were supplemented at a rate of 2% of bodyweight with a 16% CP corn-soybean meal supplement. Weights and FAMACHA were collected at weaning and then weekly for the duration of the study. Fecal egg counts (FEC) and packed cell volumes (PCV) were collected bi-weekly. Lambs were dewormed when FAMACHA score was a 3 or greater. Ultrasound measures of rib eye area (REA) and fat depth were obtained at study conclusion and lambs were marketed at the same graded auction as the group sold at weaning. There was no significant difference in FEC and PCV data values during project duration (P = 0.32) (P = 0.19). Fewer deworming treatments were necessary in TX-sired lambs at 19% (7/36) whereas SU-sired lambs required 42% (15/36) (P = 0.04). REA and fat depth measurements were not significant between sired breeds (P = 0.21) (P = 0.50). Texel-sired lambs received a $0.26/Kg greater premium than the SU-sired lambs at weaning. Texel-sired lambs received a $0.29/Kg greater premium than the SU-sired lambs after the conclusion of grazing. These data demonstrate that Texel-sired lambs required fewer dewormer treatments and received premiums when marketed at a graded auction.

Abstract Improvements in growth and carcass conformation through terminal sire crossbreeding systems may improve lamb value in a pasture-based system. Therefore, the aim of this study was to compare the effects of different terminal sires on parasitism, growth, composition, and marketability of grazing lambs. Suffolk (SU; n = 2) and Texel (TX; n = 2) sires were mated to commercial ewes at the WVU Organic Farm. April-born lambs were managed on pasture as one group until weaning in midJune, then were separated into 3 replicates per sire breed. Lambs were rotationally grazed for 93 d with paddock movement every 10 d. Lambs were supplemented at a rate of 2% of bodyweight with a 16% CP corn-soybean meal supplement. Weights were collected at weaning and then weekly for the duration of the study. Fecal egg counts (FEC) and FAMACHA scores were collected biweekly. Lambs were de-wormed when FAMACHA score was ≥ 3. Ultrasound measures of rib eye area (REA) were obtained at study conclusion and lambs were marketed at a graded auction. Sire breed did not impact weaning weight or growth rate throughout the test. Fecal egg count was slightly higher in TX vs. SU-sired lambs (257 vs 191 eggs/g; P < 0.05). FAMACHA scores were lower in TX vs. SU-sired lambs (1.58 vs. 1.96; P < 0.0001). Fewer deworming treatments were necessary in TX-sired lambs at 10% (4/39) whereas as SU-sired lambs required 55% (22/40) (P < 0.0001). TX-sired lambs had greater REA (11.57 vs 9.42 cm2; P < 0.0001) and graded better at the saleyard. Grading was set to a 6 pt scale with higher equating to higher sale price. Lambs sired by TX rams graded 5.2 and SU-sired lambs graded 3.6 (P < 0.0001). These data demonstrate that Texel-sired lambs required fewer dewormer treatments and were compositionally more desirable when marketed

Calving ease and calf mortality were studied for 4034 calves produced in second and later parities at two locations, Brandon and Manyberries, by contemporary populations of first-cross dams mated to four terminal sire breeds, Charolais (C), Chianina (Chi), Limousin (L) and Simmental (S). The dams represented 10 F1 crosses, the Hereford × Angus (HA) and nine crosses produced by mating C, L and S Bulls with Hereford, Angus and Shorthorn cows. Calving difficulty and mortality were higher among males (P < 0.0001) than females. Calving ease was not influenced by location, but postnatal mortality, particularly of males, was substantially less at Brandon (P < 0.0001). Differences in calving ease among terminal sire progeny groups were not significant when the four breeds were mated to HA dams, but all paired or three-way comparisons involving the Limousin indicated the highest proportion of unassisted births (P < 0.0001) and the lowest incidence of difficult births (P < 0.006) for this sire breed. Terminal sire differences in postnatal mortality were not present among progeny from the HA dams, nor were they observed in the paired comparisons involving progeny of the Chi vs. those of the other three terminal sire breeds. For this trait, however, the paired comparisons among progeny from C, S and L sires indicated a ranking of C > S > L (P < 0.04). Breed of dam's dam (Hereford, Angus, Shorthorn) had no influence of calving ease or mortality, but breed of dam's sire (C, L, S) was important with progeny from L-sired dams having the highest incidence of unassisted births (P < 0.01) and the highest incidence of postnatal mortality (P < 0.06). The proportion of unassisted births increased as the experiment progressed (P < 0.001) and may have been associated with advancing age of the dams. There was, however, a large location × year interaction for this trait (P < 0.002) with Manyberries recording substantially greater calving difficulty than Brandon during the first 3 yr. Interactions involving calf sex, year of birth, breed of terminal sire and location were identified for calving ease. Calf mortality generally increased with increasing calving difficulty but the relationship between calving ease and mortality was influenced by the degree of precalving environmental stress on the dam. Key words: Beef cattle, crossbreeding, calving ease, mortality

AbstractCarcass and eating quality characteristics of crossbred wether and female lambs sired by Charollais (C), Suffolk (S) and Texel (T) rams out of Mule ewes (Bluefaced Leicester ♂ × Scottish Blackface ♀ or Swaledale ♀J)were evaluated in a study carried out over a 3-year period in an upland flock. A total of 10 unrelated rams of each breed were used as sires. Lambs (no. = 280) were selected for slaughter at the same estimated subcutaneous fat level on four occasions within each year (i.e. at weaning in July and at approx. monthly intervals thereafter). Following slaughter, the left side of each carcass was physically dissected. A loin joint from lambs slaughtered in the 2nd and 3rd years of the study (no. = 184) was used to evaluate eating quality.Suffolk-sired lambs were heavier at slaughter (S: 42·2; C: 41·0; T: 40·7 (s.e. 0·35) kg) but had similar killing-out proportions compared with the other two breeds (S: 444; C: 450; T: 452 (s.e. 26) g/kg). Texel-sired lambs had higher lean proportion (S: 543; C: 550; T: 567 (s.e. 4·4) g/kg) and lower total carcass fat proportion (S: 240; C: 242; T: 233 (s.e. 5·3) g/kg) compared with S and C sired lambs. Bone proportion was similar for C and T lambs but was higher for S (S: 199; C: 191; T: 191 (s.e. 2·1) g/kg). Lean: bone (S: 2·75; C: 2·90; T: 2·99 (s.e. 0·037)) and lean:fat (S: 2·38; C: 2·40; T: 2·54 (s.e. 0·034)) ratios were higher for T-sired lambs. Female lambs were lighter (40·4 v. 42·2 (s.e. 0·24) kg), and had proportionately more intermuscular fat than wethers (122 v.118 (s.e. 1·3) g/kg) but the sex differences for other tissue proportions were small. Carcass weights and total carcass fat proportions increased and lean proportions decreased across the four slaughter dates. There were no effects of breed or sex on eating quality. However, samples from lambs slaughtered at weaning were judged to be more tender than those slaughtered later in the season.

The Difference

This experiment was designed to investigate the effect of high levels of pollard in the ration on the growth and carcase quality of growing pigs. Twenty-four gilts and twenty-four male castrate weaner pigs of mean liveweight 23.4 kg were each fed one of four rations in a wet form in individual stalls twice daily until they were slaughtered at a mean liveweight of 86.5 kg. The control ration was 81.9 per cent wheat and 15.0 per cent soybean meal, with added minerals and vitamins. In the other three rations, the wheat and soybean meal portion was replaced by 48.4, 67.8, and 96.9 per cent pollard. Feed allowance was adjusted to give a similar intake of digestible energy for all rations. There was no significant difference between treatments in rate of liveweight gain or in efficiency of utilization of digestible energy. Efficiency of utilization of air-dry feed decreased as level of pollard in the ration increased. These differences were significant except for the difference between the rations containing 48.4 and 67.8 per cent pollard. There was a significant decrease in dressing percentage with each increase in the level of pollard in the ration. Backfat thickness was significantly less in pigs fed rations containing 67.8 and 96.9 per cent pollard than in pigs fed the other two rations. Gilts grew more rapidly, utilized feed and digestible energy more efficiently and produced carcases with greater eye muscle indices and higher appraisal scores than the male castrates. There were no digestive disturbances on any of the rations and all were readily eaten. The results indicate that the relationship between protein quality k d net energy in pollard is of an order normally occurring in well-balanced rations.

The characteristics and retail yield of carcases of 482 Angus, Charolais and Hereford sired progeny out of straightbred Hereford (HxH), and first-cross Brahman x Hereford (BxH), Simmental x Hereford (SxH) and Friesian x Hereford (FxH) dams were evaluated. The cattle had been raised and slaughtered for either the vealer (both sexes), yearling domestic (both sexes) or the heavy export steer market. The data were analysed within market type, and at a constant age at slaughter (281, 478 and 829 days for vealer, yearling domestic and heavy export carcases respectively) and also at a constant hot P8 fat depth (4.6, 7.8 and 14.9 mm for the three markets respectively) and constant hot carcase weight (160, 200 and 343 kg for the three markets respectively). At a constant age, carcases of Charolais sired progeny were significantly (P < 0.05) heavier (8-16%, depending on market type), leaner, had larger eye muscle area and higher dressing percentage than those of Angus and Hereford sired progeny. This resulted in 12 to 17% (P < 0.05) more kg of boneless saleable meat (retail yield) from carcasses of Charolais sired progeny. At a constant hot P8 fat depth, the magnitude of the sire breed differences increased, whereas at a constant hot carcase weight, the differences became non-significant or were reduced in magnitude. At a constant age, progeny of BxH dams had higher ( P < 0.05) dressing percentage than those of the other dam breeds for all market types except the vealer market. Progeny of FxH dams had more (P < 0.05) channel and kidney fat than those of the other dam breeds, even at a constant hot P8 fat depth. Retail yield, as a percentage of the boned side, was highest for carcases of progeny of BxH dams and lowest for those of progeny of FxH dams (70.2% and 70.3% v. 69.1% and 69.2%, for vealer and yearling domestic carcases respectively, at a constant age). Sire and dam breed effects for the individual primal cuts, as percentages of the boned side, were not significant for most of the primal cuts, and where significant, the differences were very small.

Reading and writing performance was observed in 30 adult aphasic patients to determine whether there was a significant difference when stimuli and manual responses were varied in the written form: cursive versus manuscript. Patients were asked to read aloud 10 words written cursively and 10 words written in manuscript form. They were then asked to write on dictation 10 word responses using cursive writing and 10 words using manuscript writing. Number of words correctly read, number of words correctly written, and number of letters correctly written in the proper sequence were tallied for both cursive and manuscript writing tasks for each patient. Results indicated no significant difference in correct response between cursive and manuscript writing style for these aphasic patients as a group; however, it was noted that individual patients varied widely in their success using one writing form over the other. It appeared that since neither writing form showed better facilitation of performance, the writing style used should be determined according to the individual patient’s own preference and best performance.

SummaryFour thromboplastin reagents were tested by 18 laboratories in Europe, North-America, and Australasia, according to a detailed protocol. One thromboplastin was the International Reference Preparation for ox brain thromboplastin combined with adsorbed bovine plasma (coded OBT/79), and the second was a certified reference material for rabbit brain thromboplastin, plain (coded CRM 149R). The other two thromboplastin reagents were another rabbit plain brain thromboplastin (RP) with a lower ISI than CRM 149R and a rabbit brain thromboplastin combined with adsorbed bovine plasma (RC). Calibration of the latter two reagents was performed according to methods recommended by the World Health Organization (W. H. O.).The purpose of this study was to answer the following questions: 1) Is the calibration of the RC reagent more precise against the bovine/combined (OBT/79) than against the rabbit/plain reagent (CRM 149R)? 2) Is the precision of calibration influenced by the magnitude of the International Sensitivity Index (ISI)?The lowest inter-laboratory variation of ISI was observed in the calibration of the rabbit/plain reagent (RP) against the other rabbit/plain reagent (CRM 149R) (CV 1.6%). The highest interlaboratory variation was obtained in the calibration of rabbit/plain (RP) against bovine/combined (OBT/79) (CV 5.1%). In the calibration of the rabbit/combined (RC) reagent, there was no difference in precision between OBT/79 (CV 4.3%) and CRM 149R (CV 4.2%). Furthermore, there was no significant difference in the precision of the ISI of RC obtained with CRM 149R (ISI = 1.343) and the rabbit/plain (RP) reagent with ISI = 1.14. In conclusion, the calibration of RC could be performed with similar precision with either OBT/79 or CRM 149R, or RP.The mean ISI values calculated with OBT/79 and CRM 149R were practically identical, indicating that there is no bias in the ISI of these reference preparations and that these reference preparations have been stable since their original calibration studies in 1979 and 1987, respectively.International Normalized Ratio (INR) equivalents were calculated for a lyophilized control plasma derived from patients treated with oral anticoagulants. There were small but significant differences in the mean INR equivalents between the bovine and rabbit thromboplastins. There were no differences in the interlaboratory variation of the INR equivalents, when the four thromboplastins were compared.

ABSTRACT The purpose of this study was to investigate whether a difference could be demonstrated between crystalline insulin extracted from normal human pancreas, and crystalline insulin extracted from bovine and porcine pancreas. Using Hales & Randle's (1963) immunoassay no immunological differences could be demonstrated between human and pig insulin. On the other hand, a significant difference was found, between pig and ox insulin. An attempt was also made to determine whether an immunological difference could be demonstrated between crystalline pig insulin and crystalline human insulin from non diabetic subjects on the one hand and endogenous, circulating insulin from normal subjects, obese subjects and diabetic subjects on the other. No such difference was found. From these experiments it is concluded that endogenous insulin in normal, obese and diabetic human sera is immunologically identical with human, crystalline insulin from non diabetic subjects and crystalline pig insulin.

Abstract Aim: The aim of this study was to compare the reversal of shear bond strength of composite to bleached enamel immediately after bleaching followed by application of various antioxidant solutions. Material and Methods: Seventy central incisors were divided into seven groups. Groups I and II served as unbleached and bleached controls respectively. Groups III, IV, V, VI and VII served as the experimental groups and were subjected to 37.5% hydrogen peroxide bleaching followed by 10 min application of 10% sodium ascorbate, 25% alpha-tocopherol, 6.5% grape seed extract, 5% lycopene and 5% green tea extract respectively. Following composite bonding, shear bond strength was determined and the results were analyzed using ANOVA followed by Post Hoc Multiple Comparisons test. Results: The bond strength values for Group I (positive control) were maximum and significantly different than all the other groups except Grape seed extract group (Group V). When compared to Group II (bleached control), all the groups showed significantly higher bond strength. Significant difference in the bond strength values were seen between Group III (10% sodium ascorbate) and Group V. Also values for Group V were significantly different from Group VI (5% lycopene). All the other values showed insignificantly different results. Conclusion: All the antioxidant solutions improved the shear bond strength values after bleaching but only Grape seed extract application reversed the values to the non bleached levels. Lycopene was least effective. Other antioxidants showed comparable results.
