Changes in the sheep industry over the last 20 years represent a trend that is unlikely to be reversed. The farm gate value of wool production has decreased from over $6 billion to ~$2.5 billion and the value of sheep meat has increased from $0.5 to $2.2 billion. Wool and meat are now on an equal footing in terms of the economic value of each sector of the industry. Future profitability of both wool and sheep meat production depends on achieving a high rate of productivity gain and improving quality attributes valued by consumers. Wool and sheep meat cannot compete on price or volume with synthetics and cotton in the textile market or with chicken and pork in the meat market. Differentiation based on quality and consistency needs to be measurable and clearly understood by consumers. The combination of genetic selection and good management can deliver improved productivity gain. Skills development and training will be essential for the industry to fully utilise available knowledge and new technologies.

Risk Categories

An economic model of the costs of sheep flystrike has been modified to examine the effect of a given change in the risk of breech strike as if it applied to the entire wool-producing industry, rather than to individual wool producers. Within each region (high rainfall, sheep/cereal and pastoral zones), the model sets the proportion of the sheep population in low, medium and high risk categories and calculates the estimated level of strike for untreated sheep in those groups. The costs related to breech strike can be calculated according to the original model. The risk of breech strike can then be adjusted to any required level, the proportion of sheep in each category adjusted and the costs recalculated according to the adjusted risk. The model estimated that a 50% reduction in the risk of breech strike would decrease the number of sheep requiring preventive treatment to about one-third of previous levels, but only provide a small reduction in costs related to struck sheep, due to the large increase in the number of sheep no longer receiving preventive treatment. There would be only small reductions in costs related to crutching and mulesing sheep unless much larger reductions in strike risk occurred. The overall benefit of a 50% reduction in the risk of strike would be $0.23–0.27 per sheep. If this reduction in strike risk occurred across all regions this could provide a benefit to the Australian sheep industry of $15 million. The model found that if mulesing was not used in any of the sheep then the use of preventive treatment would increase so that 93% rather than only 60% received chemical treatment, and reduction of the risk of breech strike by 50% provided benefits of $0.40 per sheep. Therefore, the estimated benefits would be greater than $0.27 per sheep in situations where the current level of risk is very high.

The Impact

The meat and eating quality characteristics of 627 crossbred lamb progeny from 20 Poll Dorset sires were studied. The sires were selected on the basis of Australian sheep breeding values (ASBVs) for postweaning growth (PWWT), depth of loin muscle (PEMD) and subcutaneous fat (PFAT). Lambs were either weaned at 20- or 30-kg liveweight and then within each of these groups held at their weaning weight for 55 days or fully fed, giving four treatment groups. Restricted lambs were realimentated subsequent to the period of feed restriction and the lambs within each treatment group were slaughtered when their mean liveweight reached 45 kg.Shear force of the M. longissimus thoracis et lumborum (LL) decreased with temperature at pH 6.0, increased with LL ultimate pH and decreased as sarcomere length increased. Within LL aged for 5 days there was no difference between (P > 0.05) between treatments for shear force. There was a treatment effect on M. semimembranosus (SM) shear force, such that for a sire having an average ASBV PWWT of 9.34, topsides from lambs early weaned and restricted had significantly (P < 0.05) lower values. Further within these same lambs, i.e. early weaned and restricted, as the sire ASBV PWWT increased there was a significant (P < 0.001) reduction in shear force. There was a significant (P < 0.05) increase in sensory tenderness as the sire ASBV PFAT increased and across the range of ASBV PFAT this represented a change in sensory tenderness of four points. Overall liking increased with an increase in the temperature at pH 6.0 (P < 0.05) with a coefficient of 0.43 ± 0.19. There was a significant (P < 0.05) interaction between feeding level and the sire ASBV PFAT, such that for restricted fed lambs overall liking increased as the ASBV PFAT increased (coefficient 2.80 ± 0.89) after adjusting for temperature at pH 6.0, but this is not the case for fully feed lambs (coefficient –0.01 ± 0.89). Subtle interactions between sire ASBVs and growth path suggest that the impact of a period of restriction and refeeding on meat and eating quality will be meditated by the sire genetics.

Australian Sheep

The Sheep Cooperative Research Centre’s role to facilitate the transformation of the Australian sheep industry is complicated by the extensive nature of the industry across some 31 000 small to medium farming enterprises, linking to both sheep meat and wool supply chains. Close integration of the market with research and adoption through a product development focus is enabling a staged product development process while providing the management flexibility needed for development of each product type within target markets. This paper presents the basis of the New Product Development Framework and the adoption strategies used across the Sheep Cooperative Research Centre programs to accelerate utilisation of products developed out of research. These strategies include: communication; training coordination; network engagement and use of key influencers; supply chain engagement and the use of specific adoption research tools.

Main Factor

Calculations on the relative efficiencies of cattle, sheep and pigs as meat producers indicate that the main factor limiting the energetic efficiency of sheep meat production is the low average fecundity of the ewe (Blaxter, 1968). Nevertheless with an estimated ‘biological ceiling’ of five lambs per ewe per pregnancy, and a potential mean lambing interval of 6 months (Wilson, 1968), the sheep industry is much further from achieving its biological ceiling than any other form of domestic livestock production. Because these estimates are based on the performance of specific individuals one must question their attainment on a flock basis. Furthermore, even if the necessary technical information were available, its adoption on a commercial scale may be prohibitive on economic grounds. These uncertainties should not deter us from seeking a greater understanding of the basic factors controlling ewe productivity, nor from attempting to integrate this knowledge into existing production systems.

Improve Production Efficiency

This overview discusses how precision sheep management could be utilised in the Australian sheep industry to improve production efficiency and reduce animal welfare concerns due to low monitoring frequency by stockpeople. The concept of precision sheep management is described. This is a system in which sheep are managed as individuals or small groups rather than as a (whole) flock. Precision sheep management utilises the application of radio frequency identification technology, enabling producers to better monitor sheep in extensive situations, and contribute to improved efficiency of management and sheep welfare. Examples of combining radio frequency identification with other technologies such as walk-over-weighing and Pedigree Matchmaker are discussed. These technologies provide producers with tools to improve the cost effectiveness of, and labour efficiency associated with, collecting data on individual animals. The combined technologies should also improve consistency and reliability of information, enhancing decision-making by producers, for example, from regular monitoring of biometric variables such as liveweight, or calculating breeding values to enable superior genetic comparisons over time.

Meat Market

Plant-based meat analogues, edible insects, and cultured meat are promising major meat alternatives that can be used as protein sources in the future. It is also believed that the importance of meat alternatives will continue to increase because of concerns on limited sustainability of the traditional meat production system. The meat alternatives are expected to have different roles based on their different benefits and limitations. Plant-based meat analogues and edible insects can replace traditional meat as a good protein source from the perspective of nutritional value. Furthermore, plant-based meat can be made available to a wide range of consumers (e.g., as vegetarian or halal food products). However, despite ongoing technical developments, their palatability, including appearance, flavor, and texture, is still different from the consumers’ standard established from livestock-based traditional meat. Meanwhile, cultured meat is the only method to produce actual animal muscle-based meat; therefore, the final product is more meat-like compared to other meat analogues. However, technical difficulties, especially in mass production and cost, remain before it can be commercialized. Nevertheless, these meat alternatives can be a part of our future protein sources while maintaining a complementary relationship with traditional meat.

The analysis of some systems of green areas and public parks of the metropolitan area of Guadalajara, other cities of our country Mexico and Latin America, shows common problems such as the deficit of urban green spaces, insecurity, unemployment, and uncertainty with a social exclusion in these areas of stress. Likewise, the lack of economic value of the services provided by such natural systems as recreation is added. Together they are important factors in the allocation of territories destined to this use with respect to others that generate Urban speculation. Therefore, it is proposed to develop a typology of green areas appropriate to the needs of the metropolitan region. It will facilitate the production of inventories that estimate indicators of territorial cohesion, governance, economic profitability, social, environmental quality and innovation, as well as incorporating new technologies that improve geographic information systems and internet media that support management.
