Brazilian beef systems contribute 14.9% of global beef production, therefore given climate change concerns, there is a clear need to reduce environmental impacts while maintaining economic viability. This study evaluated the hypothesis that steroid implant use in Brazilian beef cattle would reduce resource use, greenhouse gas (GHG) emissions and economic costs of production, thereby improving environmental and economic sustainability. A deterministic model based on beef cattle population demographics, nutrition and performance was used to quantify resource inputs and GHG emissions per 1.0 × 106 kg of hot carcass weight (HCW) beef. System boundaries extended from cropping input manufacture to cattle arriving at the slaughterhouse. Beef systems were modeled using herd population dynamics, feed and performance data sourced from producers in four Brazilian states, with additional data from global databases. Implants were used in calves, growing and finishing cattle at low (LI), medium (MI), and high (HI) levels of performance enhancement, compared to nonimplanted (NI) controls. Feed use results were used in combination with producer-derived input costs to assess the economic impacts of implant use, including production costs and returns on investment. Improved FCE, ADG, and carcass weights conferred by implant use reduced the number of cattle and the time taken to produce 1.0 × 106 kg HCW beef. Compared to NI controls, the quantities of feed, land, water and fossil fuels required to produce 1.0 × 106 kg HCW beef was reduced in implanted cattle, with reductions proportional to the performance-enhancing effect of the implant (HI > MI > LI). Implant use reduced GHG emissions per 1.0 × 106 kg HCW beef by 9.4% (LI), 12.6% (MI), or 15.8% (HI). Scaling up the MI effects to represent all eligible Brazilian cattle being implanted, revealed avoided GHG emissions equivalent to the annual exhaust emissions of 62.0 × 106 cars. Economic impacts of implant use reflected the environmental results, resulting in a greater margin for the producers within each system (cow-calf through to finishing). The 6.13% increase in kg of HCW beef produced generates a cost reduction of 3.76% and an increase in the return on invested capital of 4.14% on average. Implants offer the opportunity for Brazilian beef producers to demonstrate their dedication to improving environmental and economic sustainability through improved productivity, although care must be taken to avoid negative trade-offs.

A considerable body of evidence has reported the beneficial effects of improving productivity on reducing environmental impacts from livestock production. However, despite the negative impacts of animal diseases on reproduction, growth and milk production, there is little information available upon the impacts of animal disease on greenhouse gas emissions (GHGe). This study aimed to partially address this knowledge gap by investigating the effects of globally important vaccine-preventable diseases on GHGe from various livestock systems, namely: intensive dairy, extensive beef, commercial swine and backyard poultry production. Methods Simple deterministic models were developed within Microsoft Excel to quantify the impacts of livestock disease on productivity (defined as total milk and/or meat yield, MMY) adjusted for disease prevalence both at the population level (high or low), and at the herd or flock level. Disease-induced changes in MMY were applied to the GHGe per kg of milk or meat according to the consequent changes in livestock populations required to maintain milk or meat production. Diseases investigated comprised foot and mouth, brucellosis, anthrax, lumpy skin disease, classical swine fever, porcine reproductive and respiratory syndrome (PRRS), low and high pathogenicity avian influenza (LPAI and HPAI), avian infectious bronchitis and Newcastle disease. Results All diseases investigated had multifactorial impacts on total MMY, yet diseases that increased mortality in breeding or growing livestock (e.g. anthrax, classical swine fever and HPAI) showed greater impacts on GHGe per unit of milk or meat produced than those that primarily affecting yields or reproduction (e.g. brucellosis or LPAI). Prevalence also had considerable effects on potential GHGe. For example, maintaining backyard poultry meat production from a 100,000 hen population with 70% prevalence of HPAI increased GHGe by 11,255 MT CO 2 eq compared to a 30% prevalence at 3475 MT CO 2 eq above the baseline (0% prevalence). Effective reduction of the prevalence of PRRS in swine from 60 to 10%, FMD in beef cattle from 45 to 5% prevalence, or AIB in poultry from 75 to 20% prevalence would reduce GHGe intensities (CO 2 eq/kg CW) by 22.5%, 9.11% and 11.3% respectively. Conclusions Controlling livestock disease can reduce MMY losses at the farm level, which improves food security, reduces GHGe and enhances livestock system sustainability.

The beef industry faces a significant challenge in producing sufficient food to supply the requirements of the growing population, while maintaining a culture of continuous improvement and reducing environmental impacts per unit of beef produced. Since the late 1970’s, the US beef industry made significant efficiency gains that improved resource use and reduced greenhouse gas (GHG) emissions, and considerable opportunities exist for making greater gains in future. However, beef producers’ future access to specific management practices or technologies may be constrained by consumer perceptions.

All stakeholders within the livestock industry face a considerable challenge in achieving a balance between economic viability, environmental responsibility and social acceptability; and thus maintaining sustainable food production. This is exacerbated by information about farming practices and management systems that accentuate consumer concerns and lead to confusion as to the roles of productivity, efficiency and animal health in modern agriculture. The suggestions that intensive farms or large-scale herds have negative effects on cattle health; that we can assess cattle welfare by applying anthropomorphic philosophies; and that extensive systems are inherently beneficial to the environment, appear to be intuitively correct. Yet these suppositions are not as simple as they are often presented in mass media articles aimed at the consumer and lead to a multitude of other questions. Although it is tempting to try and overcome these issues by providing factual information, we cannot overcome negative publicity simply by supplying data and statistics. As an industry, we need to combine improved communication mechanisms with a better understanding of how consumer food-buying decisions are made to ensure future social acceptability and sustainability.

Optimizing efficiency in the cow-calf sector is an important step toward improving beef sustainability. The objective of the study was to use a model to identify the relative roles of reproductive, genetic, and nutritional management in minimizing beef production systems' environmental impact in an economically viable, socially acceptable manner. An economic and environmental diet optimizer was used to identify ideal nutritional management of beef production systems varying in genetic and reproductive technology use. Eight management scenarios were compared to a least cost baseline: average U.S. production practices (CON), CON with variable nutritional management (NUT), twinning cattle (TWN), early weaning (EW), sire selection by EPD using either on-farm bulls (EPD-B) or AI (EPD-AI), decreasing the calving window (CW), or selecting bulls by EPD and reducing the calving window (EPD-CW). Diets to minimize land use, water use, and/or greenhouse gas (GHG) emissions were optimized un...

“Big is bad…small is beautiful…”. We are constantly bombarded by marketing messages suggesting that only small-scale, local, artisan food is environmentally sustainable. Although consumers celebrate efficiency in vehicle mileage per litre or smart-phone battery life, it appears to be a negative concept when associated with dairy production, as it is linked with large “factory” farms and the perception that farmers are more concerned with profit than with caring for livestock.

It is reported that supplementing pregnant ewes with supra-optimal levels of vitamin E improves neonatal lamb vigour and growth rate (Merrell, 1998). The biochemical mechanism behind these observations has yet to be elucidated as several studies report negligible placental vitamin E transfer in ruminants (Van Saun et al., 1989); consequently, lambs may be clinically deficient in this nutrient at birth and achieve a satisfactory vitamin E status via colostrum ingestion. Lamb vitamin E status may be further diminished by the addition of polyunsaturated fatty acids (PUFAs) to the maternal diet. However, PUFA supplementation demonstrably enhances foetal and neonatal development in human studies (Morley, 1998) although these effects have not been investigated in ruminants to any depth. The objective of this experiment was to investigate the effects of dietary vitamin E in combination with long-chain PUFA supplementation of ewes on ewe and lamb performance.
