As the Federal Statistical Office (Destatis) reports, according to preliminary results, commercial slaughterhouses produced 6.8 million tons of meat in 2023. That was 4.0% or 280,200 tons less than in the previous year. This means that domestic meat production has fallen for the seventh year in a row since its peak in 2016 (8.25 million tonnes). After comparatively slight declines from 2017, meat production fell by 8.1% in 2022 compared to the previous year, and now meat production fell again significantly in 2023. A total of 47.9 million pigs, cattle, sheep, goats and horses as well as 702.2 million chickens, turkeys and ducks were slaughtered in slaughterhouses in 2023.

With 43.8 million animals slaughtered in 2023, the number of pigs slaughtered fell by 7.0% or 3.3 million compared to the previous year. The number of pigs of domestic origin slaughtered fell by 7.7% to almost 42.3 million animals. The number of imported pigs slaughtered in German slaughterhouses, however, rose by 19.5% to 1.5 million animals. In total, slaughterhouses produced around 4.2 million tons of pork in 2023. That was 6.8% or 306,500 tons less than in 2022. Compared to the record year of 2016, around 1.4 million tonnes less pork were produced in 2023, which corresponds to a decline of over a quarter (-25.1%).

Infectious diseases are among the factors that most limit the efficiency of livestock production, since its appearance entails losses associated with increased mortality, a decrease in the feed transformation index, increased veterinary costs and the loss of value of infected carcasses. 

A good example of this can be found in the pork sector, which currently provides the most widely consumed red meat worldwide, and in the health and economic risk that the Aujeszky’s disease, one of the most important swine virus diseases. In Spain, Aujeszky’s disease has been eradicated in domestic pigs, but it is present in wild boar, which carries a significant risk of reinfection of the domestic swine herd. The direct economic losses associated with an outbreak of Aujeszky’s disease for a pig farm free of the disease could be between €350 and €800 per adult female per year.

A new epidemiological model, developed by researchers from the University of Lleida and the Instituto de Investigación en Recursos Cinegéticos (IREC), has revealed the effects of combining management practices and vaccination on the control of Aujeszky’s disease in a standard pig production system under different epidemiological scenarios. It is a computational model of population dynamics (known as the “PDP model” for its acronym in English: Population Dynamics P systems), a novel tool that is especially suitable for studying complex dynamic problems efficiently, since it allows to simultaneously consider a large number of interactions between different processes.

The model results indicate that, once a diagnosis of infection is confirmed on a farm, early vaccination of the majority of the population (we are talking about more than 75%) is critical to reduce the spread of the virus and minimize its impact on pig productivity. For their part, management practices seem to have an insignificant effect on virus control, which could be associated with its great ease of spread.

A team of Chinese researchers supported by a US-based researcher investigated whether weaner pigs are provided with polysaccharides from a Japanese seaweed known as “kombu” or Laminaria japonica. The team published about their findings in the Journal of Veterinary Sciences in a research article published in December 2023. They investigated the effects of adding L. japonica polysaccharides to the diet on growth performance, faecal digestive enzyme activity, serum biochemical indices, and free amino acids in weaned piglets. The team looked into these kombu polysaccharides as they are comprised of a combination of different sugar residues. Those compounds exhibit a variety of beneficial biological functions.

The research team selected 120 healthy barrows for this study, which lasted 21 days. They assigned all piglets randomly assigned to 4 treatments according to the initial body weight. The team supplemented each concentration of L. japonica polysaccharides (0, 100, 200, or 400 mg/kg) to the basal diet. The research team computed average daily gain (ADG), average daily feed intake (ADFI) and gain-to-feed ratio (G:F). At the end of the experiment, a single piglet from each pen, with a body weight closely aligned with the pen’s average, was selected, and the team obtained blood as well as faecal samples.

The results showed that polysaccharide supplementation at dosages of 200 and 400 mg/kg showed a significant enhancement in the ADG and ADFI of weaners during days 0-21.  Better growth performance was due to the improved digestive enzyme activities in the faeces and increased appetite and energy absorption of piglets. Polysaccharide supplementation at dosages of 200 and 400 mg/kg significantly increased the faecal amylase activity of piglets, due to the polysaccharide’s prebiotic activity, which promotes starch digestion and absorption. In addition, the polysaccharides linearly increased faecal amylase and lipase activities.

Regarding amino acid content in serum in the 400 mg/kg group increased levels of histidine and asparagine were observed in piglets due to increased protein digestion and absorption. In addition, polysaccharide supplementation at a dosage of 200 mg/kg reduced serum methionine and phenylalanine contents compared to piglets supplied the polysaccharides at a dosage of 100 mg/kg. At all levels (100, 200 and 400 mg/kg), polysaccharide supplementation did not impact the serum levels of e.g. glucose, total cholesterol and ammonia of weaned piglets. That is probably due to the short experimental period.

The authors concluded that supplementation of 200 and 400 mg/kg of L. japonica polysaccharides to the feed could increase growth performance and the amylase activity in the faeces of weaned piglets. They expect this to improve the nutrient metabolism ability of weaned piglets.

The porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most dangerous pathogens for the swine sector. In addition to affecting the reproductive system in breeding sows and the respiratory tract in young animals, it is usually associated with other secondary diseases, which is why it has become the health problem that generates the most economic losses in the swine industry worldwide.

In their research on PRRSV, researchers from the University of Córdoba (UCO) in Spain investigated the role of so-called ‘transcription factors’, which are molecules responsible for the differentiation of cells of the immune system, and concludes that three of these molecules are expressed with greater intensity in the most virulent strains of the pathogen.

The UCO research team led by Librado Carrasco has managed to identify the role of three key molecules in the immune defense against this pathogen in three target organs of the pig: the lung, thymus and tracheobronchial lymph node. Precisely, three fundamental organs in triggering the immune response and in which the virus replicates the most once it comes into contact with the body.

To do this, the research work has analyzed these organs from 70 pigs in three different groups, one of them not infected by this pathogen, which functions as a control group, and two other groups infected with two strains of different virulence of the virus. Specifically, the study has focused on what is known as ‘transcription factors.’ Again, these molecules regulate the differentiation of cells involved in the immune system. In this sense, as highlighted by researcher Inés Ruedas-Torres, one of the main authors of the study, the results indicate that three of these molecules (called T-BET, FOXP3 and EOMES) are expressed with greater intensity and earlier in the strain analyzed with the highest virulence.

“Immune defense is not based on a single response but on a sum of several elements,” said Irene Rodríguez-Gómez, another of the researchers who participated in the work. Along these lines, as reflected in the study, each of these three proteins that research has revealed as fundamental in the immune response plays a different role in the body’s defense. While the first of the three molecules analyzed (T-BET) is related to the activation of macrophages that phagocytize the virus, the second (FOXP3) prevents, among other functions, the inflammatory response of the infected organism from being too intense. For its part, the third molecule (EOMES) is responsible for the activation of lymphocytes responsible for inducing the death of cells infected by the virus.

Currently, there are several types of commercial vaccines against PRRSV, but none of them, the researcher emphasizes, prevents secondary infections or offers complete protection due to the high mutation of the virus. The long-term objective, therefore, is to develop new vaccine candidates that offer total immunity against the different strains of the pathogen.

Rabobank’s Global Pork Quarterly Q1 2024 report said early indications are that pork production will slow as key regions face contraction in the sow herd. According to Chenjun Pan, senior analyst of Animal Protein at Rabobank, forecasts point to a potential decrease in global pork trade during the first part of 2024 as high inventories in importing countries reduce demand. “We’re looking at a soft market for pork exports, especially with the ongoing crisis in the Red Sea and Suez Canal complicating European shipments to Asia,” Pan said. A trend in the report was the expected decline or flat production in China, the United States, and some European countries during 2024, with disease pressure adding to overall industry challenges.

Although production headwinds could be ahead, feed prices continue to come down, with corn and soybean prices falling 15% to 25% year over year. “Lower feed costs are a welcome relief for pig farmers, improving margins in a time of uncertainty, Pan said. However, Rabobank still cautions that weather-related volatility could impact supply and price movements.

Brazil’s pork production continues to be on the rise as some regions continue to look at declining herds. The group pointed to uneven growth worldwide with African swine fever (ASF) outbreaks and loss-making pressure, especially with breed herd reduction in Asia, particularly China. “We expect disease outbreaks to create ongoing uncertainty in 2024,” Pan said. “Meanwhile, productivity will continue to improve in 2024, driven by genetic gains, better farm management and cost reduction strategies.”

Even with all the market difficulties, pork consumption remains resilient to inflationary conditions around the world. Rabobank expects a mild improvement in global pork consumption during the year. “Pork continues to be a staple protein, holding its ground against more expensive meat like beef,” Pan said.

The World Organisation for Animal Health (WOAH) is warning veterinary authorities and the global pig industry against the use of non-compliant and poor-quality vaccines for African swine fever (ASF). In a statement issued October 18, WOAH stressed the importance of the use of only high-quality ASF vaccines with proven efficacy and safety, and which have been subject to regulatory evaluation and approval in accordance with WOAH international standards.

“The research community has been working to develop an effective vaccine and recent announcements of modified live vaccines being approved or tested in some countries have raised hopes for the availability of new effective tools to contain the ASF epidemic,” WOAH said. The use of non-compliant and poor-quality vaccines may not confer any protection against ASF and risks spreading vaccine viruses that could result in acute or chronic disease, WOAH said. Additionally, these vaccine viruses could also recombine with field strains to generate novel strains. The world’s first ASF vaccines were authorized by Vietnam in July, when two vaccines were cleared for domestic use in pigs in the country.

Approval came after widespread testing in the country’s swine herds. The government reported the vaccines to be 95% effective. The vaccines – NAVET-ASFVAC (from Navetco National Veterinary Joint Stock Co.), and the AVAC ASF LIVE vaccine (from AVAC) — were jointly developed by U.S. scientists with two different commercial partners in Vietnam. In some other Asian countries, registration of the AVAC vaccine is underway. A third vaccine, DACOVAC-ASF2 vaccine from the Dabaco Group, is reportedly under evaluation in Vietnam. In the Philippines, applications are under consideration for the importation of four ASF vaccines. A Phase 1 trial was completed in May, and three farms in different provinces have been selected as the locations of Phase 2 field trials, the source reports. Authorities are awaiting complete documentation from a second vaccine company. In order to bring to an end the country’s four-year battle to eliminate ASF, the government has allocated PHP1.5 billion ($26.4 million) for the vaccination of the nation’s hogs.

Steady gains in production in combination with weaker consumption continue to pressure global pork markets and trade. That is a brief summary of the latest quarterly pork report by Rabobank. All in all, the bank stated, lower feed costs, better animal health and improved productivity bolster industry optimism despite challenging returns and uncertain consumption trends. After productivity challenges in 2022 and 2023, several key growing regions appear to be turning a corner, the bank wrote. While disease pressure is still an issue in some regions, overall herd health has improved. In a news release, the bank’s senior animal protein analyst Christine McCracken said: “A renewed focus on cost reduction – given inflationary pressures resulting in the elimination of less productive operations – is also contributing to a rebound in production per sow. Although this improvement is a welcome trend and lowers costs, the additional production is compounding regional oversupplies and weighing on the market.” At the same time, breeding herd reductions in most geographies outside Europe and South Korea are slow, despite ongoing margin pressure and limited optimism for a quick turnaround in global trade, the bank said. Corn and soybean prices moved lower in the third quarter of 2023, after a good North American harvest helped rebuild stocks and expectations for a large South American crop emerged, the bank wrote. Consumers are adjusting to inflationary pressures, yet pork remains a dietary staple and overall consumption trends remain stable. However, pack types and sales channels continue to shift. McCracken concluded, “In the final quarter of 2023, we expect global trade to remain slow given large inventories, relatively high domestic production, and low pork prices in key importing regions. Rising EU pork prices may also limit export volumes.” In Europe, pork production in the 27 EU countries and the UK contracted sharply, Rabobank reported. In the first 7 months of 2023, this would come down to 8.6% year-on-year. In Germany, the sow herd had contracted by 2% in June 2023 when compared to December 2022. One year earlier, the contraction had been 12% in the same period. Contraction in the sow herd will slow down, the bank expects, due to improved producer margins. Exports remain weak on relatively high prices and weaker global economies.

Fermented rapeseed meal has a positive effect on improving the growth performance and intestinal health of growing pigs, according to Chinese research. Researchers from the Institute of Animal Husbandry at Sichuan Agricultural University claim that the results of a recent study could also help develop new protein sources for animal nutrition and the feed industry. The study, the results of which have been published in the Journal of Animal Nutrition, involved 30 growing pigs randomly assigned to three treatments: corn-soybean meal diet (CSD), rapeseed meal diet (RSD) and fermented rapeseed meal diet (FRSD). The results showed that compared with RSD, feeding FRSD increased the average daily gain and final body weight of pigs (P<0.01). Compared with RSD feeding, FRSD feeding increased the apparent digestibility of crude protein, acid detergent fibre and ether extract in pigs (P<0.01). The FRSD group had higher apparent ileal digestibility of His, Thr, Lys and SER than the RSD group (P<0.01). Digestible energy, metabolic energy and nitrogen utilisation were higher in the FRSD and CSD groups than in the RSD group (P<0.01). Compared with the RSD, the FRSD diet decreased the serum concentration of leptin but significantly increased the concentration of immunoglobulin (IG) A, IgC, IgM and the enzyme activities of amylase, lipase and trypsin in the pancreas (p<0.05). In terms of intestinal health, the FRSD diet not only increased the expression of occludin in the small intestinal epithelium (P<0.05) but also increased the expression of SGLT1 and CAT1 genes in the jejunum (P<0.05) compared to the RSD diet.

Global pork markets are being affected by sluggish economic growth, weak consumption and recurrent disease outbreaks, and according to Rabobank’s latest Quarterly Pork Report, global trade is expected to weaken after a strong first half of the year. While sluggish economic growth has impacted consumers around the world, pork continues to hold a relatively stable position on consumers’ plates, notes the Rabobank report. The reasons for the weaker performance vary from region to region. In Europe, pork consumption remains under pressure from persistently high prices. In the US, demand was slightly below expectations at the start of the summer as uncooperative weather and poor air quality hampered the start of the barbecue season. And in China, pork consumption remains weak due to a weak economy and heat waves across the country. Chenjun Pan, senior Animal Protein analyst at Rabobank, expects global trade to weaken in the second half of 2023. “Inventories of frozen pork in China are high due to weak consumption, putting pressure on imports. In addition, tighter supply in the EU is limiting shipments from the region,” said Pan. The Rabobank report highlights that pork supply in the EU and UK fell in the first four months of 2023, with double-digit declines in some countries. This tight supply is supporting high prices, which in turn is putting pressure on consumption. Meanwhile, in China, pork supply continues to outstrip demand, putting pressure on prices and leading to multi-month losses for producers. Rabobank adds that the liquidation of the country’s sow herd will continue in the second half of the year. Supply is also plentiful in the US, where producers have relatively healthy balance sheets after two years of outsized profits. However, given the forecast losses, Rabobank expects the US herd liquidation to continue until 2024.

An influential select committee report has called on the government to take steps to support increased nitrogen fertiliser production in the UK. The Environment, Food and Rural Affairs (EFRA) Committee has called on the Government to examine the incentives offered by competing nations and to produce an action plan within the next six months. The committee said nitrogen fertiliser plays a vital role in UK food security and the production of the ammonia used in it creates large amounts of carbon dioxide gas as a by-product, which is vital to the food supply chain. However, there is only one nitrogen fertiliser plant in the UK, which undermines UK food security and the lack of alternatives has led to a significant increase in UK prices at a time when the sector is already under significant price pressure. Given the importance of nitrogen fertiliser to UK food production and food security, the Government should set out how it will ensure its continued production in the UK. Given that Europe and the United States are intervening directly in their own fertiliser sectors, it seems completely remiss for the UK to do nothing. Responding to the publication of the report, Ed Barker, head of policy and external affairs at the Agricultural Industry Confederation (AIC), said: “We welcome the key findings of the EFRA Select Committee report. The AIC will continue to work with the committee and MPs as part of its efforts to represent the interests of the UK’s agricultural supply industry.”
