CEALVET, a Spanish company focused on the innovation, design and marketing of products aimed at improving animal welfare, especially in the poultry sector, last September 2023, won the Eurostars 3 call with its new project “Bioacoustics Automatic Evaluation system for poultry Health” (BAEHealth), in which the French LDC Group also participates in the experimental part on the farm. The BAEHealth project consists of a web application and a set of sensors based on artificial intelligence, which will offer an innovative service to automatically detect, in real time and quantitatively, the level of well-being of birds through the animals' vocalizations, from their birth in the incubator until the end of the production cycle in the company, including transport. The use of bioacoustics as a welfare detection method was selected based on previous test results obtained by CEALVET's research and development engineering team: the relationship of vocalizations to farm production rates, the relationship of vocalizations with the level of CO2 concentration, and the detection of stress resulting from the vocalizations emitted. The main objectives of the BAEHealth project are: • [...]

Interview with Tesa Panisello (CEO of CEALVET SLu)

16 February, 2024|

The Spanish company CEALVET SLu develops the first bioacoustic sensor for the poultry industry called VocalData. VocalData is an additional tool as part of the global poultry welfare strategy. By focusing on the acoustic expression of animals, we do not define what their well-being is, but rather they vocalize it, sing it. “Using information from VocalData, it is possible to predict production parameters and measure animal welfare in both commercial farms and hatcheries.” How was your project born? Our project was conceived about 4 years ago, in parallel with the application of our product Licuicel Complex, a complementary feed for early nutrition administered in the hatchery. Our need was to measure the benefit on the welfare of the treated animals, observing the improvement produced and the reduction of stress in the chicks. In its publication this year, EFSA, in the “Bird welfare” section 2022 20(9), referred to the work of CEALVET by identifying a significant change in the acoustic parameter of frequency in stress calls emitted by birds (Ginovart-Panisello et al., 2020 Acoustic Description of the Soundscape of [...]

Early feeding: Nutritional strategies to improve the health and well-being of chicks after hatching

14 June, 2023|

The “hatch window” represents the 24–48-hour period in which hatching begins and ends for all eggs from the same batch. During this time, the chicks remain in the incubator until all the eggs hatch, after which they undergo routine treatments, including selection, vaccination, sexing, and sorting, before being transferred to the farm. In conventional commercial hatcheries, when chicks hatch, they have no food or water available until they are transported to the farms (delayed access). Long transports to their destination could exacerbate store depletion and dehydration through excessive thermoregulation and stress, which could affect body weight and chick mortality rates. European Union legislation stipulates that newly hatched chicks may be transported within the first 72 hours of life, including a maximum transport time of 24 hours, without food or water. This recommendation is because the metabolic reserves stored in the yolk sac may be sufficient for the chick during the first three days after hatching. However, chick mortality during the first week of life may reflect the stress of the transport process, as well as the fact that increased mortality is the most [...]

Natural solutions against Salmonella in poultry: Prepare for battle!

30 June, 2022|

Salmonella infections in poultry are a problem for consumers, as Salmonella-contaminated animal products pose a serious risk to human health. Since the use of antibiotics needs to be reduced to maintain their effectiveness, control of Salmonella in poultry requires alternative solutions. This article shows how organic acids and phytomolecules can help combat this complex disease. Salmonellosis: what it is, how it works and why it is a problem Salmonellosis is a zoonosis that can be easily transferred from animals to people. The transfer can occur in different ways: - Direct contact with an infected animal. - Handling or consuming contaminated animal products, such as eggs or raw pork, turkey, and chicken. - Contact with infected vectors (insects or domestic animals) or contaminated equipment. Frozen or raw chicken products, as well as eggs, are the most common means of transmission of Salmonella infections of animal origin in humans. The following graph shows a clear relationship between the occurrence of Salmonella in laying hen flocks and the occurrence of the disease in humans: Figure 1. [...]

Innovative nutritional specialties for poultry: butyrate and its benefits

29 June, 2022|

For many years, the intestinal health of broilers was supported and preserved by the use of antimicrobial growth promoters (AGPs), antibiotic substances that, added to the feed in certain amounts, have subtherapeutic effects that favor animals’ productive performance. In 2006, the European Union banned the use of these substances as a precautionary measure to prevent AGPs from increasing antimicrobial resistance in bacteria and their subsequent transmission to humans. It is very likely that intestinal health problems in chickens were partially masked by the routine use of AGPs. Since their ban in Europe, alternative strategies have been sought to control the intestinal health of birds. These research efforts have revealed the complexity of the intestinal ecosystem. Short chain fatty acids (SCFAs) have been widely used as feed additives in recent years. SCFAs are a group of molecules that contain from one to seven carbon atoms and that exist as straight or branched chain compounds. Among them, acetic, propionic and butyric acid are the predominant forms. Butyric acid also has multiple other health-promoting effects, such as mediating the immune response, inhibiting the growth of harmful [...]

Early feeding in chicks: how to implement it

28 June, 2022|

The “hatching window” represents the 24-48 hour period during which the eggs hatch. The newly hatched chicks remain in the incubator until all of them have hatched, after which they undergo routine treatments such as selection, vaccination, sexing and grading, before being transported to the farm. Depending on the length of the hatching window, routine procedures and transport to the farm, the chickens can remain under fasting conditions for a period that could reach, according to legislation (EC No 1/2005), up to a maximum of 72 hours. Chicks need to learn to consume feed as soon as possible to allow their digestive system to undergo a rapid anatomical and physiological transformation, as well as help the development of the immune system. They also need to start consuming water in a short time to compensate for the dehydration they experience from hatching to their arrival at the farm, thus also favoring the consumption and digestibility of the feed. Fasted chicks are more susceptible to pathogens, lose weight easily, critical tissue development and survival can be compromised, and those that survive often exhibit stunted growth, [...]
