Cím:	Calming Hungarian Grey Cattle in Headlocks Using Processed Nasal Vocalization of a Mother Cow / Lenner, Ádám; Papp, Zoltán Lajos; Szabó, Csaba; Komlósi, István

Megjegyzések:	Two of the fundamental pillars of animal welfare are stress-free management and treatment. The extensive farming of cattle involves minimal human contact. However, regular veterinary treatments and vaccinations require restraining cattle with headlocks in crates in order to ensure the safety of workers. Since these animals are usually kept in herds and mainly graze freely, this procedure is a high-stress situation for them. Animals can vocalize a number of sounds as part of their behavior. For example, dams have a special nasal vocalization toward their calves with a calming effect. We hypothesized that, by removing noises, selecting the most representative part, and creating a repeated sound, this kind of nasal vocalization would have a calming effect on cattle restrained in headlocks. Our results show that the played processed nasal vocalization of a mother cow reduced the stress experienced by cattle during the test.Abstract Sound analysis is an important field of research for improving precision livestock farming systems. If the information carried by livestock sounds is interpreted correctly, it could be used to improve management and welfare assessment in this field. Therefore, we hypothesized that the nasal vocalization of a mother cow could have a calming effect on conspecifics. The nasal vocalization in our study was recorded from a mother cow (not part of the test herd) while it was licking its day-old calf. The raw sound was analyzed, cleaned from noises, and the most representative vocalization was lengthened to two minutes. Thirty cows having calves were randomly selected from eighty Hungarian grey cattle cows. Two test days were selected, one week apart; the weather circumstances in both days were similar. The herd was collected in a paddock, and the test site (a restraining crate with a headlock) was 21 m away from them. The cows from the herd were gently moved to the restraining crate, and, after the installation of the headlock, Polar (R) heart rate monitors were fixed on the animals. The recording of the RR intervals was carried out for two minutes. On day one of the test, the processed nasal sound was played to every second cow during the heart rate monitoring. When the sound ended, the heart rate monitor was removed. On test day two, the sound and no sound treatments were switched among the participating cows. At the end of the measurement, the headlock was opened, letting the animals out voluntarily, and a flight test was performed along a 5 m distance. The time needed to pass the 5 m length was measured with a stopwatch and divided by the distance. The RR intervals were analyzed with the Kubios HRV Standard (ver. 3.5.0) software. The following data were recorded for the entire measurement: average and maximum heart rate; SD1 and SD2; pNN50; VLF, LF, and HF. The quasi-periodic signal detected in the sound analyses can hardly be heard, even when it is enhanced to the maximum. This can be considered a vibration probably caused by the basis of articulation, such as a vibration of the tongue, for example. The SD2/SD1 ratio (0.97 vs. 1.07 for the animals having no sound and sound played, respectively, p = 0.0110) and the flight speed (0.92 vs. 1.08 s/m for the animals having no sound and sound played, respectively, p = 0.0409) indicate that the sound treatment had a calming effect on the restrained cows. The day of the test did not influence any of the measured parameters; therefore, no effect of the routine was observed. The yes-no sequence of the sound treatment significantly reduced the pNN50 and flight speed values, suggesting a somewhat more positive association with the headlock and the effectiveness of the processed nasal sound. In conclusion, we have demonstrated that, by means of sound analyses, not only information about individuals and the herd can be gathered but that, with proper processing, the sound obtained can be used to improve animal welfare.

Cím:	The characteristic of fosterage in a hungarian grey cattle (Bos primigenius taurus hungaricus) stock / Ádám Lenner ; Evelin Török ; István Komlósi

Megjegyzések:	The concept of fosterage appears in different ways at different organisational levels. The literature mainly describes artificial fostering methods for dairy cattle. For beef cattle, it is only partly used. The aim of our study was to investigate the development, rate, and efficiency of natural fostering in a Hungarian Grey cattle herd of nearly 200 dams at the Szamárháti farm of the Tiszatáj Public Foundation in Hungary. The observation period lasted from 2018 to 2020. During the three years, there were a total of 335 calvings, 79 offspring died, sucklings was recorded in 1173 cases, 16 dams and the consequent development of foster-mothering were described. Our research seeks to reveal whether it makes sense to maintain the foster dam's nursing activity or whether drying off is necessary in the case of natural fostering. The results show that a quarter of dams fostered offspring after losing their calves. The age of the fostered calves were between one day and one month, with their 205 day-adjusted weights 11-29% above the average of the non - fostered ones. The calves of the foster dams also died in one of the following years, which may justify the culling of these individuals. The age of the dams and the number of their calvings varied. In the future, we should also monitor the offspring care of the fostered heifers and the social behaviour of the fostered offspring.

Cím:	Changes in the relationship between Hungarian Grey cows (Bos primigenius taurus hungaricus) and their calves in the period from calving to four months of age / Ádám Lenner, Péter Ragán, István Komlósi
Dátum:	2022
ISSN:	1587-1282
Megjegyzések:	The ability of cows to care for their offsprings is a very important trait concerning beef cattle. Maternal instincts are highly influenced by breed, specific cow, and social and rearing environment. In 2020, at the Szamárháti farm of the Tiszatáj Public Foundation, we selected 15 dam-calf pairs and studied them for four months from the birth of the calves. We grouped calf-rearing behaviors according to strength and analyzed the related changes during the program. At the beginning of the relationship, "standing close to each other" (53%) and "suckling" (24%) characterized the pairs. After the first month, "standing or lying separated" grew by 69%, and "vocalization" by both an imals fell by 66%. Even though the daily frequency of suckling decreased by 34% as the calves grew older, it remained a typical element of the relationship. Over time, the bond between the animals gradually weakened. This natural process of separation takes a month to complete.

Cím:	Study of changes in the strength of connection between grey cattle cows and their offspring after weaning / Lenner Ádám, Ragán Péter, Komlósi István
Dátum:	2021
ISSN:	1587-1282
Megjegyzések:	It is important to minimize stress for cattle because of animal welfare and profitability. This study aims to reveal how long after abrupt weaning the cow and her offspring show a need to rebuild the connection if physical barriers are removed and distances disappear. The research was carried out on Szamárhát Farm owned by the Tiszatáj Foundation, Hungary. In the autumn of 2019, thirty-one calves were weaned, randomly selected from 81 grey cattle cows' offspring. The oldest calf was 10 months old, while the youngest one was 6 months old on the day of weaning. They were divided into three groups and reunited with the cows during the first, third, and fifth weeks after weaning. Each reunion happened in the early afternoon and the cow and her offspring spent 24 hours together again. The formation and the strength of the connection were recorded for an hour three times during this period, first in the afternoon, then in the morning, and the next afternoon. It can be seen that both parties showed the need to form the connection during the first week after weaning because the bond made between them was obvious in a short time. The connections proved to be strong. However, neither the cows nor their offsprings showed any intention to form strong connections in the third and fifth weeks. In the majority of the cases, no connection was formed.
