As a component of the second term of the Cooperative Research Centre (CRC) for Cattle and Beef Quality, a project to further test and validate the effects of varying nutritional growth paths pre-finishing and slaughter on cattle of varying genetic potential for meat yield and eating quality was designed and implemented. This project, ‘Regional Combinations’, was a multi-site experiment, using Bos taurus cattle generated at 4 locations across southern Australia. The design of imposing different growth paths between weaning and finishing on cattle with specific genetic potential is common across sites. Treatment and interaction effects on beef production and meat quality were examined within and across sites. This paper describes the experimental designs, generation of experimental cattle at the various sites and the measurements, collection and storage of the data for multi-site analyses.

Meat Science

The Cooperative Research Centre for the Cattle and Beef Industry (Meat Quality) was formulated in 1992 by CSIRO, the University of New England (UNE), NSW Agriculture and Queensland Department of Primary Industries (QDPI) to address the emerging beef quality issue facing the Australian beef industry at that time: the demand from domestic and export consumers for beef of consistent eating quality. An integrated program of research involving meat science, molecular and quantitative genetics and growth and nutrition was developed. To meet the expectations of the Commonwealth of Australia, additional projects dealing with animal health and welfare and environmental waste generated by feedlot cattle were included. The program targeted both grain- and grass-finished cattle from temperate and tropical Australian environments. Integration of research on this scale could not have been achieved by any of the participating institutions working alone. This paper describes the financial and physical resources needed to implement the program and the management expertise necessary for its completion. The experience of developing and running the Cooperative Research Centre confirms the complexity and cost of taking large numbers of pedigreed cattle through to carcass and meat quality evaluation. Because of the need to capture the commercial value of the carcass, it was necessary to work within the commercial abattoir system. During the life of the Cooperative Research Centre, abattoir closure and/or their willingness to tolerate the Research Centre’s experimental requirements saw the Cooperative Research Centre operations move to 6 different abattoirs in 2 states, each time losing some precision and considerable revenue. This type of constraint explains why bovine meat science investigations on this scale have not previously been attempted. The Cooperative Research Centre project demonstrates the importance of generous industry participation, particularly in cattle breeding initiatives. Such involvement, together with the leadership provided by an industry-driven Board guarantees early uptake of results by beef industry end-users. The Cooperative Research Centre results now provide the blueprint for genetic improvement of beef quality traits in Australian cattle herds. Heritabilities of beef tenderness, eating quality, marbling, fatness and retail beef yields are now recorded. Genetic correlations between these traits and growth traits are also available. Outstanding sires for beef quality have been identified. Linked genetic markers for some traits have been described and commercialised. Non-genetic effects on beef quality have been quantified. Australian vaccines against bovine respiratory disease have been developed and commercialised, leading to a reduction in antibiotic use and better cattle performance. Sustainable re-use of feedlot waste has been devised.

Abstract Improving beef quality is important task for livestock in Kazakhstan. Almost all indicators characterizing the quality of carcasses and beef are evaluated after slaughter. Their use in breeding is limited (Legoshin G.P. 2010). For lifetime assessment of carcasses in pedigree and slaughter cattle, Aloka 500B, EXAGO, EVO ultrasonographs are used, using which there is a high coincidence of the lifetime forecast of muscular development over the eye muscle area with the indicator in carcasses after slaughter of animals (Bisembaev A.T. 2019). A high correlation of prognosis of ribeye area with live weight of animals was noted (Lisitsyn A.B. 2010). The aim of the project is to study the effectiveness of in vivo determination of meat quality using an ultrasonic scanning device. Tasks: to determine the ribeye area, the fat of the cattle using an EXAGO ultrasonograph; compare the ribeye area, the fat of the slaughter cattle, determined using an EXAGO ultrasonograph and measured on the carcass after slaughter. The studies were carried out on pedigree bull-calves of the Kazakh white head (85 animals), Auliekol (101 animals) breeds aged 14–15 months and on the feeding stock (6 animals) with a live weight of more than 943 lb. The ribeye area, the fat were obtained: Kazakh white head had 23.2 sq.in and 0.10 in, Auliekol – 20.4 sq.in and 0.09 in. The animals studied after slaughter yielded full-bodied carcasses, while the slaughter yield averaged 56.3%. The correlation between live weight level and ribeye was r=0.97. The coincidence of ribeye, measured by an ultrasonograph with a post-mortem measurement averaging 93.8%. The introduction of ultrasound methods for determining beef productivity in beef industry will allow livestock husbandry to become cost-effective and improve the beef quality. The results of ultrasound images for the carcass traits will be applied in selection and breeding work.

At the commencement of the Cooperative Research Centre for the Cattle and Beef Industry (Meat Quality) participating scientists were encouraged to anticipate the methods and channels that might be used to deliver the Cooperative Research Centre’s research outcomes to beef industry end-users. This important step was seen as the completion of the process, which began with the beef industry issue, leading then to formulation of the Cooperative Research Centre concept, initiation of the research program, completion of research and finally commercialisation or delivery of products and processes to industry. This paper deals with techniques, institutions and commercial arrangements employed to achieve delivery and adoption of diverse outcomes of the Cooperative Research Centre.

Up to now, genetic selection in cattle has been directed in favour of muscle growth, which changes muscle characteristics, and hence meat quality. One key concern, that now needs examination, is to understand the relationships between muscle growth and muscle characteristics related to meat quality. To achieve such a goal, muscles of divergently selected animals were analysed by three complementary approaches: (i) determination of muscle biochemical characteristics, (ii) identification of differentially expressed genes using transcriptomic and proteomic tools, (iii) identification of Single Nucleotide Polymorphisms (SNP) within candidate genes.

Meat Quality Traits

Market demand for a reliable supply of beef of consistently high eating quality led the Cooperative Research Centre for Cattle and Beef Industry (Meat Quality) to initiate a crossbreeding progeny test program to quantify objective and sensory meat quality differences between straightbred and first-cross Brahman cattle. Brahman, Belmont Red, Santa Gertrudis, Angus, Hereford, Shorthorn, Charolais and Limousin sires were mated to Brahman females over 3 years to produce 1346 steers and heifers in subtropical northern Australia. Calves were assigned within sire by age and weight to one of three market endpoints (domestic, Korean or Japanese), one of two finishing environments (subtropical or temperate) and one of two finishing diets (pasture or feedlot). Average carcass weights were 227, 288 and 327 kg for domestic, Korean and Japanese markets respectively. Only steers were finished for the Japanese market. The effects of sire breed, finishing regime, market endpoint and sex on sensory meat quality of four attributes score (CMQ4), ossification score and Warner-Bratzler shear force (SF), instron compression (IC), ultimate pH and percent cooking loss (CL) on the M. longissimus thoracis et lumborum (LT) and M. semitendinosus (ST) were determined. Straightbred Brahmans had the highest SFLT (5.39 ± 0.07; P < 0.001), ICLT (1.89 ± 0.02; P < 0.05) and CL in both muscles (P < 0.05). Straightbred Brahmans were the only genotype that failed to meet minimum CMQ4 grading standards (38.3; P < 0.001). Progeny with up to 75% Brahman content successfully met minimum objective and sensory meat quality consumer thresholds for tenderness (IC <2.2 kg, SF <5.0 kg; CMQ4 >46.5). There was little difference between crossbred progeny for most meat quality traits. All feedlot-finished animals were slaughtered at domestic, Korean and Japanese market weights by 24 months of age, with minimal differences in objective measures of meat quality between markets. The IC measures for all sire breeds were below 2.2 kg, indicating connective tissue toughness was not an important market consideration in feedlot-finished animals slaughtered by 24 months of age. Pasture finishing adversely affected all meat quality traits (P < 0.001) except CLST, with Korean and Japanese market animals having unacceptably tough SF, IC and CMQ4 measures. This was attributed to their older age at slaughter (31 and 36 months respectively), resulting from their seasonally interrupted growth path. While domestic animals slaughtered at 25 months of age off pasture had unacceptably high SF and IC, CMQ4 was acceptable. Subtropical feedlot animals had slightly more desirable (n.s.) SF and IC relative to temperate feedlot animals, whereas temperate feedlot animals had higher CMQ4 (P < 0.001). Genotype × environment interactions were not important.

The Individual

In its first 7-year term, the Cooperative Research Centre (CRC) for the Cattle and Beef Industry (Meat Quality) identified the genetic and non-genetic factors that impacted on beef eating quality. Following this, the CRC for Cattle and Beef Quality was established in 1999 to identify the consequences of improving beef eating quality and feed efficiency by genetic and non-genetic means on traits other than carcass and beef quality. The new CRC also had the responsibility to incorporate results from the first Beef CRC in national schemes such as BREEDPLAN (Australia’s beef genetic evaluation scheme) and Meat Standards Australia (Australia’s unique meat grading scheme that guarantees the eating quality of beef). This paper describes the integrated research programs and their results involving molecular and quantitative genetics, meat science, growth and nutrition and industry economics in the Beef CRC’s second phase (1999–2006) and the rationale for the individual genetics programs established. It summarises the planned scientific and beef industry outcomes from each of these programs and also describes the development and/or refinement by CRC scientists of novel technologies targeting increased genetic gains through enhanced measurement and recording in beef industry herds, thereby ensuring industry use of CRC results.

Research within the health and welfare program of the Cooperative Research Centre for Cattle and Beef Quality has delivered important improvements to the Australian cattle industry. Vaccines to assist with the control of bovine respiratory disease were developed and commercialised from Australian isolates of Mannheimia haemolytica and pestivirus (mucosal disease). Our understanding of the benefits of weaning cattle by confinement and hand feeding in yards (yard weaning) has been consolidated, and yard weaning has been adopted as ‘best practice’ for cattle production in the temperate zones of Australia. The importance of good temperament for improved growth rates and reduced morbidity during feedlot finishing, and for adaptation to stressors such as road transport, has been demonstrated. In response to this knowledge, industry is increasingly measuring flight time for use in breeding programs and feedlot management. The risk to meat quality of stressors such as mixing unfamiliar cattle in the weeks preceding slaughter or acute stress in the last 15 min before slaughter has been described. Adoption of these findings through Quality Assurance schemes will assist in assurance for the community and for export markets of the welfare standards of the Australian cattle and beef industry. This review provides details of the experiments that led to these achievements and to some improved understandings of temperament and behaviour of beef cattle.

Guidelines And Recommendations

In 2012, preliminary guidelines were published addressing sample quality, data acquisition and reduction, presentation of scattering data and validation, and modelling for biomolecular small-angle scattering (SAS) experiments. Biomolecular SAS has since continued to grow and authors have increasingly adopted the preliminary guidelines. In parallel, integrative/hybrid determination of biomolecular structures is a rapidly growing field that is expanding the scope of structural biology. For SAS to contribute maximally to this field, it is essential to ensure open access to the information required for evaluation of the quality of SAS samples and data, as well as the validity of SAS-based structural models. To this end, the preliminary guidelines for data presentation in a publication are reviewed and updated, and the deposition of data and associated models in a public archive is recommended. These guidelines and recommendations have been prepared in consultation with the members of the International Union of Crystallography (IUCr) Small-Angle Scattering and Journals Commissions, the Worldwide Protein Data Bank (wwPDB) Small-Angle Scattering Validation Task Force and additional experts in the field.
