Abstract The Indonesian Beef Cattle Research Station (BCRS) has undertaken conservation and improvement of Grati-Ongole crossbred cattle (POGASI Agrinak) by distributing selected cattle into some provinces in Indonesia. This study aimed to evaluate the productive performance of the calves born in different agroecological zones. Sixty-seven male and female POGASI Agrinak were distributed in Indonesia including in upland (e.g., in 50 Kota, Payakumbuh, one bull, and nine cows and Pule, Trenggalek, one bull, and eight cows) and in low land (e.g., in Jember, one bull and six cows, Indramayu, one bull and six cows, Situbondo, 25 bulls and Tanahlaut, South Kalimantan, ten bulls). The cattle were kept under diverse environmental and management systems. The natural mating system was applied in communal pens using selected bulls. The parameters observed were the number of calves and the birth weight. It resulted in 168 calves born in the upland and five calves born in low land. While the birth weight of calves born in lowland and upland was 25.8 + 1.6 kg and 25.2 + 2.4 kg respectively. Meanwhile, the birth weight of calves in BCRS was 25.3 + 25 kg. To conclude, the birth weight both in BCRS and in those sites’ ex-situ was comparable.

Abstract This study aimed to evaluate the productivity of the Belgian Blue x POGASI crossbred cattle raised at the Beef Cattle Research Station located at Grati, Pasuruan. Therefore, data on productivity, such as body measurements, birth, weaning, and yearling weight, as well as reproductive performances, were collected and analyzed using t-tests from 11 calves of Belgian Blue x POGASI (F1) crossbred cattle consisting of 5 males and 6 females, and also 11 calves of POGASI cattle consisting of 3 males and 8 females. From the results, there were significant differences (P<0.05) in body measurements between Belgian Blue x POGASI crosses and the POGASI cattle. Specifically, the Belgian Blue x POGASI crossbred calves had birth, weaning, and a yearling weight of 34.45±6.55 kg, 218.08±37.99 kg and 368.05±41.77 kg, respectively, as well as age at first estrus and libido of 12.99±3.13 months and 16.53±1.45 months, respectively. Also, the crossbred calves had body weight at first estrus and libido of 413.25±38.46 kg and 489.75±42.60 kg, respectively. In conclusion, the productivity of Belgian Blue x POGASI crossbred calves was higher than that of POGASI calves. Therefore, it was concluded that BB x POGASI calves produced greater performances than POGASI calves.

Liveweights and liveweight gains of straightbred Hereford and F1 Africander x Hereford crossbreds were compared from birth to 379 days of age at the Brigalow Research Station (24�50�S., 149�48'E.), Theodore in central Queensland. Over three calvings, there was no significant (P>0.05) effect of breed on day of birth or birth weight of calf, but at 127, 2 13 (weaning) and 379 days of age, F1 AfricanderxHereford crossbreds were significantly (P<0.05) heavier than straightbred Hereford cattle. The advantage was 7% to weaning and increased to 14% by 379 days of age. There were significant breed x sex interactions for liveweights at 127, 213 and 379 days of age, but not for birth weight. Hereford males failed to express superiority over females. A breed x dam age interaction was apparent for liveweights at 127, 213 and 379 days of age. The greatest difference between the two breed groups was in the progeny suckled by 2-year-old dams. Generally, sire effects were not significant within breeds.

This study was performed to update and generate prediction equations for converting digestible energy (DE) to metabolizable energy (ME) for Korean Hanwoo beef cattle, taking into consideration the gender (male and female) and body weights (BW above and below 350 kg) of the animals. The data consisted of 141 measurements from respiratory chambers with a wide range of diets and energy intake levels. A simple linear regression of the overall unadjusted data suggested a strong relationship between the DE and ME (Mcal/kg DM): ME = 0.8722 × DE + 0.0016 (coefficient of determination (R2) = 0.946, root mean square error (RMSE) = 0.107, p < 0.001 for intercept and slope). Mixed-model regression analyses to adjust for the effects of the experiment from which the data were obtained similarly showed a strong linear relationship between the DE and ME (Mcal/kg of DM): ME = 0.9215 × DE − 0.1434 (R2 = 0.999, RMSE = 0.004, p < 0.001 for the intercept and slope). The DE was strongly related to the ME for both genders: ME = 0.8621 × DE + 0.0808 (R2 = 0.9600, RMSE = 0.083, p < 0.001 for the intercept and slope) and ME = 0.7785 × DE + 0.1546 (R2 = 0.971, RMSE = 0.070, p < 0.001 for the intercept and slope) for male and female Hanwoo cattle, respectively. By BW, the simple linear regression similarly showed a strong relationship between the DE and ME for Hanwoo above and below 350 kg BW: ME = 0.9833 × DE − 0.2760 (R2 = 0.991, RMSE = 0.055, p < 0.001 for the intercept and slope) and ME = 0.72975 × DE + 0.38744 (R2 = 0.913, RMSE = 0.100, p < 0.001 for the intercept and slope), respectively. A multiple regression using the DE and dietary factors as independent variables did not improve the accuracy of the ME prediction (ME = 1.149 × DE − 0.045 × crude protein + 0.011 × neutral detergent fibre − 0.027 × acid detergent fibre + 0.683).

Apricot (Prunus armeniaca L.) is an economically important tree species globally cultivated in temperate areas. Italy has an ample number of traditional varieties, but numerous landraces are abandoned and at risk of extinction because of increasing urbanization, agricultural intensification, and varietal renewal. In this work, we investigated the morphological and genetic diversity present in an ex-situ collection of 28 neglected varieties belonging to the so-called “Vesuvian apricot”. Our aim was to understand the level of diversity and the possible link between the promotion of specific fruit types (e.g., by public policies) and the intraspecific variation in apricot. The combination of five continuous and seven categorical traits allowed us to phenotypically distinguish the varieties; while fruit quality-related attributes displayed high variation, both apricot size and skin colour were more uniform. The twelve fluorescent-based Simple Sequence Repeats (SSRs) markers identified cultivar-specific molecular profiles and revealed a high molecular diversity, which poorly correlated with that described by the morphological analysis. Our results highlighted the complementary information provided by the two sets of descriptors and that DNA markers are necessary to separate morphologically related apricot landraces. The observed morphological and genetic differences suggest a loss of diversity influenced by maintenance breeding of specific pomological traits (e.g., skin colour and size). Finally, our study provided evidence to recommend complementary strategies to avoid the loss of diversity in apricot. Actions should pivot on both the promotion of easily identified premium products and more inclusive biodiversity-centred on-farm strategies.

Growth performance, carcass characteristics and meat quality of European and British crossbred (EBC; no Wagyu genetics; 28 heifers and 30 steers) cattle were compared with crossbred cattle with 75% Wagyu genetics (WC; seven heifers and 14 steers) to determine the influence of Wagyu genetics on marbling grade of beef cattle fed barley-based diets in a factorial design experiment. Weaned calves (250 d average age) were fed, one of two diets (diet 1, 35% barley grain; diet 2, 40% hay cubes on DM basis, with barley silage, protein and vitamin/mineral premix) for 84 d and then fed diet 1 until they weighed 394 to 432 kg. All cattle were finished on an 80% (DM basis) rolled barley diet and slaughtered. Carcasses were graded and samples procured for meat quality and Warner–Bratzler shear force determination. Number of days on backgrounding diets to arrive at target weight (380 kg) was greater (P < 0.05) for the WC cattle, owing to relatively lower ADG, but days on the finishing diet were fewer for these cattle, compared with EBC cattle. Warm carcass yield (dressing percent) was greater (P < 0.05), but backfat depth was lower (P < 0.05) for WC cattle relative to that of EBC cattle, yet proportion of lean meat yield was similar. Eighty three percent of WC cattle carcasses had Canada AAA (small or more) marbling grade compared with 13% for EBC cattle carcasses. Mean shear force of meat samples from EBC and WC cattle was 4.2 and 3.8 kg, respectively. Results indicated that the extent of carcass marbling can be increased by incorporating Wagyu genetics but age at slaughter of WC cattle was 19 d greater than that of EBC cattle and carcass size was reduced.

Genetic structure of five populations of a locally common rice (Oryza sativa L.) landrace Jaulia from parts of Uttarakhand state of India was studied using sequence tagged microsatellite site (STMS) markers. Of these, four populations were on-farm managed, assembled from different niche environments, and one population was conserved ex situ and represented static conservation. The 16 STMS primer pairs fully differentiated the inter- and intrapopulation diversity. A total of 72 alleles were recorded with a mean of 4.5 alleles per locus. Population wise, the total number of alleles ranged from 21 to 41, with maximum number of alleles for population IC 548358 and minimum number of alleles for population IC 100051 representing static conservation. A greater number of alleles specific to populations under farmer management could be recorded. Changes in yield parameters also seemed to be affected under farmer management besides other environmental adaptations for qualitative morphological characters. The marker diversity using STMS primer pairs indicates the genetic differentiation among populations resulting from joint effects of several evolutionary forces operating within the historical and biological context of the crop landrace. The variations in adaptations, on the other hand, indicate the degree to which populations are adapted to their environments and their potential for continued performance or as donors of characters in plant breeding. Both biotic and abiotic aspects of the environment are involved.

Aarskog Syndrome

Malformations of the umbilicus are a feature of many dysmorphic syndromes including Rieger syndrome, Robinow syndrome, and Aarskog syndrome. The characteristic umbilical malformation in Rieger syndrome consists of redundant periumbilical skin which extends along the cord for an excessive distance. Although the measurement of umbilical skin length plays an important role in the neonatal diagnosis of Rieger syndrome, normal values for this measurement in healthy neonates have not been established. Umbilical skin length was measured in 104 healthy neonates. The length to which the umbilical skin extended along the cranial aspect of cord (mean 11.53 mm, SD 3.58) was significantly longer than the umbilical skin length along the caudal aspect (mean 8.71 mm, SD 2.89) (P &lt; .05). Multiple regression analysis revealed a significant association between age and umbilical skin length. Birth weight, length, and gestational age were not significantly associated with umbilical skin length when adjusted for the other three variables. No significant differences in umbilical skin length were observed between male and female groups. The above normal values should aid in the neonatal diagnosis of Rieger syndrome, and furthermore it is recommended that cranial umbilical skin length measurement be included in the examination of the dysmorphic child.

Abstract The objective of the study was to evaluate sow teat quality in relation to subsequent reproductive throughput. Data included one cohort of 42 Landrace × Large White second parity maternal line sows at the Tidewater Research Station (Plymouth, NC). Functional teats (FUNCTIONAL) were classified pre-farrow as acceptable (ACCEPTABLE) or substandard (SUBSTANDARD). Teats were categorized as SUBSTANDARD when teat size was ≤75% of ACCEPTABLE. At day 20 of lactation, ACCEPTABLE and SUBSTANDARD were assessed for the presence of a swollen mammary gland and piglets observed nursing SUBSTANDARD were recorded (24 piglets from 15 litters). Means for FUNCTIONAL, ACCEPTABLE and SUBSTANDARD were 15.07, 13.59 and 1.48 teats, respectively. Biological dam traits included birth weight (BWT), total number born (TNB), litter size at weaning (LSW) and piglet survival (LSW/TNB). Weaning weight (WWT) was considered a trait of the nurse dam. Means for TNB, LSW, litter BWT and litter WWT were 13.4, 10.9, 17.8 kg and 57.8 kg, respectively. Data was analyzed using a chi-square test for binary traits and linear mixed models for continuous traits. At weaning, a greater (P &lt; 0.01) proportion of ACCEPTABLE had a functional mammary gland when compared to SUBSTANDARD (76 vs. 47%). Within litters, piglets nursing SUBSTANDARD tended (em&gt;P = 0.09) to be 158 grams lighter at weaning in comparison to ACCEPTABLE. Yet BWT of SUBSTANDARD piglets did not differ (em&gt;P = 0.60) from piglets nursing ACCEPTABLE. Across litters, an increase in one SUBSTANDARD tended (em&gt;P = 0.07) to reduce litter WWT by 1.74 kilograms. An increase in one SUBSTANDARD tended (em&gt;P &lt; 0.07) to increase piglet survival by 3.5%. Results suggest substandard teats, identified pre-farrow, are less likely to have a functional mammary gland at weaning, impair piglet quality yet may enhance piglet survival.

SUMMARYUsing pre-weaning records of 3822 calves from 11 Victorian herds, mean male and female growth rates and corresponding sex differences were calculated for each dam age and herd-year class. From these means simple regression equations relating sex differences and growth rates were calculated. There was a close similarity between equations based on dam age means and those based on herd-year means while correlations between sex differences and male growth rates were high.These results showed that sex differences and female growth rates could be predicted reliably from the level of environment as measured by male growth rate. Sex differences predicted by these regression relationships differed markedly from those predicted by the simple multiplicative and simple additive models generally used in adjusting for sex differences in selection.The results also suggested that other differences such as breed differences may be predictable in the same way and that such differences are determined primarily by the level of environment per se rather than differences in the nature of the components contributing to that level.
