There is an industry wide perception that new season lamb has better eating quality than old season lamb. This study aims to identify differences in consumer eating quality scores between two age classes in lamb. Consumer eating quality scores from eight cuts across the carcass were evaluated from new season (NS; n = 120; average age = 240 days) and old season lambs (OS; n = 121; average age = 328 days), sourced from four different flocks. Cuts were grilled (loin, topside, outside, knuckle and rump) or roasted (leg, shoulder, rack) and scored by untrained consumers for tenderness, juiciness, liking of flavour and overall liking. There was no difference in eating quality scores between the two age classes for the loin, leg, shoulder and rack. This was similarly shown in the topside with the exception of juiciness scores where NS lambs were higher than OS lambs. There was also a lack of age difference in the outside with the exception of flock 3 where NS lambs scored higher than OS lambs for all sensory traits. Across all sensory traits, OS lambs received on average 2.8 scores lower for the knuckle and 3.1 scores lower for the rump compared to NS lambs. These results show little difference in eating quality between NS and OS lamb, and highlight the potential to develop high quality OS or “autumn lamb” products, with a similar premium price at retail as NS lambs.

The efficiency of pig production has increased considerably in recent years, but the improvement of meat quality has only recently begun to receive attention. Closer links between the producers and marketers of pigs are now resulting in a clearer understanding of the factors that lead to meat of high quality. Here, some of the major on-farm influences on meat quality are described, focussing on meat colour, water-holding capacity and eating quality.

Desirable Trait

AbstractGood eating quality is a highly desirable trait of rice which determines its commercial value and market share. However, the molecular basis of this trait remains largely unknown. Here, three high-quality conventional rice cultivars, including two superior eating quality cultivars Meixiangzhan-2 (MXZ) and Xiangyaxiangzhan (XYXZ), and one ordinary eating quality cultivar Huanghuazhan (HHZ), were analyzed by comparative metabolomics to identify the inherent mechanism for the formation of superior eating quality. The results showed 58.8% of common differential substances between MXZ vs HHZ and XYXZ vs HHZ were enriched in MXZ and XYXZ, whereas 39.2% of them were prominently decreased compared with HHZ, mainly including amino acids, carbohydrates, lipids, phenolamides, and flavonoids, which may be the primary factors leading to the differences of taste and flavor among these three cultivars. We also found that lysine derivatives and fatty acids may have a close relationship with taste. These results above provide important insights into the taste-forming mechanism of rice and will be beneficial for superior eating quality rice breeding.

Abstract Over a period of 19 years, we studied 237 breeding attempts of Spanish Imperial Eagles (Aquila adalberti) in Doñana National Park (southwestern Spain), including 29 pairs with at least one immature member, to investigate age-related effects on population fecundity. Without considering effect of territory quality, adult pairs were significantly more productive than immature pairs. Highly significant differences in breeding performance among territories were independent of age-classes of birds occupying them. Low-quality territories were more frequently occupied by immature pairs, whereas high-quality territories were occupied mostly or exclusively by adult birds. Therefore, age and territory quality appear to be interrelated. We found no effect on average population fecundity due to breeding by immature pairs.

Each year the U.S. government invests more than $86 billion on IT products and services, yet the majority of these projects fail--they are delivered late, go over budget, are canceled, are outdated when finally delivered, or do not fit the user. Due to barriers in hiring and training, the government has tended to outsource IT talent at a premium price through contractors, but the results have not changed. The small amount of technology talent that exists in government tends to be senior, and there currently are very few, viable options for high-quality, junior and mid-level technologists to find a job in government and develop into senior roles. Agile Corps is a program designed to identify, recruit, train, and retain junior and mid-level technology talent in the government. This paper presents the design research and initial prototypes of the program and service called Agile Corps and introduces and prototypes the concept of public service-learning.

Rutabagas (Brassica napobrassica Mill.) harvested in October and November contained a high level of sugars, more than 51% of dry matter. Roots harvested in September contained less sugars than those harvested later. Sugar concentration increased as much as 10% of dry weight during storage. Rutabagas harvested when the sugar concentration of dry weight reached the maximum level were of good eating quality. The optimum harvest time to obtain high quality rutabagas varied from year to year depending on weather conditions.

Abstract The European hazelnut (Corylus avellana L.; 2n=2x=22) is a worldwide economically important tree nut that is cross-pollinated due to sporophytic incompatibility. Therefore, any individual plant is highly heterozygous. Cultivars are clonally propagated using mound layering, rooted suckers and micropropagation. In recent years, the interest in this crop has increased, due to a growing demand related to the recognized health benefits of nut consumption. C. avellana cv ‘Tonda Gentile delle Langhe’ (‘TGdL’) is well-known for its high kernel quality, and the premium price paid for this cultivar is an economic benefit for producers in northern Italy. Assembly of a high-quality genome is a difficult task in many plant species because of the high level of heterozygosity. We assembled a chromosome-level genome sequence of ′TGdL′ with a two-step approach. First, 10X Genomics Chromium Technology was used to create a high-quality sequence, which was then assembled into scaffolds with cv ′Tombul′ genome as the reference. Eleven pseudomolecules were obtained, corresponding to 11 chromosomes. A total of 11,046 scaffolds remained unplaced, representing 11% of the genome (46,504,161 bp). Gene prediction, performed with Maker-P software, identified 27,791 genes (AED ≤ 0.4 and 92% of BUSCO completeness), whose function was analysed with BlastP and InterProScan software. To characterise ‘TGdL’ specific genetic mechanisms, Orthofinder was used to detect orthologs between hazelnut and closely related species. The ‘TGdL’ genome sequence is expected to be a powerful tool to understand hazelnut genetics and allow detection of markers/genes for important traits to be used in targeted breeding programs.

Meat Samples

The eating quality of 3 'cuts' of meat was assessed on carcasses of steers (n = 46) and heifers (n = 33) when slaughtered at 17 months of age, following preweaning growth restriction. Growth restriction (for 115 days to weaning) was imposed on half the group ('low'; n = 39 steers and heifers), followed by 2 periods of high-quality nutrition for all animals on (i) pastures (180 days) and (ii) on a grain diet in a feedlot (85 days). Preweaning growth rates (mean and standard error of difference) of steers and heifers on the 'high' treatment (905 v. 838 ± 35.0 g/day) were effectively halved (498 v. 434 ± 35.0 g/day) in the restricted 'low' group. However, no significant compensatory growth occurred when these weight-restricted weaners grazed high-quality pastures, nor during their period in the feedlot. At slaughter, the predicted liveweight of 'high'-growth steers was higher than that of 'low'-growth steers (477 v. 416 ± 11.5 kg) and they had a heavier carcass weight (251 v. 221 ± 7.2 kg). There was no difference between the meat quality (MQ4) scores of meat samples from 'low' or 'high' carcasses in which cuts of blade (2302 'bolar blade', AUS-MEAT 1998) scored higher than rump (2110 'rostbiff', AUS-MEAT 1998) and striploin (2140 striploin, AUS-MEAT 1998) samples. The study has highlighted the persistent effect of undernutrition in early life on final liveweights of Hereford cattle and the consequent reduction in their carcass weight. However, there was no carryover effect of early nutrition on meat quality.

`Black Ruby' is the newest plum released by the USDA stone fruit breeding program at Byron. This variety has large, firm fruit that ripens in early July, about 1 week after `Santa Rosa'. Fruit has reddish-black skin and yellow flesh. Eating quality is very good. `Black Ruby' has an upright tree similar to `Santa Rosa', except that tree health and vigor are much better than `Santa Rosa'. USDA has been breeding plums for the humid Southeast for 30 years. Goals are to combine large, firm, high-quality fruit with a disease-resistant tree that will live 8 to 10 years. Most plum varieties are short-lived in our area due to disease caused by Xanthomonas, Pseudomonas, and Xylella. Most existing varieties adapted to our climate have fruit unsuitable for commercial production. Previous USDA releases include “green plum” types `Robusto' (1980) and `Segundo' (1984); a yellow plum, `Byrongold' (1985); a black shipping plum, `Explorer' (1980); and the blood-fleshed, high-quality `Rubysweet' (1989).

Conclusion Section

To ensure the sustainable development of mountain livestock farming, the adequate remuneration of high-quality dairy products is fundamental. In this sense, communication strategies aimed at promoting mountain products and ensure better positioning and higher market prices are fundamental. The present research seeks to expand the literature regarding consumers’ willingness to pay for mountain foods by using an online real auction experiment aimed at evaluating the premium price that consumers are willing to pay for summer over winter mountain cheese, depending on the information provided concerning the taste anticipation or animal welfare. The results showed an overall small premium price given to the higher quality summer cheese; this could be, partially, due to a generally low degree of consumer knowledge about mountain dairy farming. With reference to communication strategies, the results provide evidence about the effectiveness of the rational messages founded upon sensorial characteristics and the anticipated taste of cheese. In addition, this study explored that adding a logo had no main effect on the price premium participants were willing to pay. This may be due to the fact that logos and claims, having a lower information content, are more indicated to lead the choice of consumers with a higher level of awareness. In the conclusion section, policy and agribusiness implications of the findings are provided.
