The examination of maternal qualities in the ethology of cows and their young offspring, derived from the study on adaptability and productivity of second and third-generation Aberdeen Angus cattle imported to Kazakhstan from Canadian and European selection, is presented in this paper. The findings indicate that Canadian heifers, belonging to the second generation, displayed extended feeding behavior throughout the day, dedicating 33.2 minutes or 2.2% more time to feeding compared to their European counterparts (P < 0.001). Similar disparities between groups were observed in the duration of the ruminant process. Moreover, Canadian heifers consumed water for an additional 2 minutes or 0.6%, which can be attributed to their higher daily feed intake. The calving process of Aberdeen Angus cows generally proceeded smoothly, demonstrating a well-developed maternal instinct towards their offspring. Notably, calves born from Canadian cows exhibited greater agility and achieved the ability to stand on their feet in a shorter time, with an average duration of 41.0 ± 1.60 minutes, which was 11.7% faster than European calves. Additionally, Canadian calves displayed a shorter time to locate their mother's breast, with an average duration of 68.0 ± 7.70 minutes.

Livestock body weight (BW) and average daily weight gain (ADG) are primary indicators of beef cattle productivity. The conventional method of weighing involves moving the cattle to a weighing location, which is labor-intensive, stressful for the animals and has a negative impact on their growth. An alternative approach is to use special weighing platforms attached to the drinkers to weigh the animals. This method enables daily monitoring of BW and ADG without incurring additional labor costs or stress. In this study, an experimental weighing platform, previously developed at KazATU and named after S. Seifullin, was employed to measure livestock's partial body weight (PBW). The weighing platform recorded the weights of the animals on the front legs at one-second intervals, allowing for subsequent calculation of the animals' total weight. However, due to significant weight fluctuations observed when the animals were on the platform, the accuracy of calculating the weight based on a simple average of the one-second measurements was questionable. Hence, an algorithm was developed to determine live weight by analyzing the primary data from the scales and identifying moments of animal immobility during drinking. The calculated results were compared with both mean and median values and data from Kazakhstan's information base of selection and breeding work (IBSBW). The experimental method exhibited a stronger correlation (r = 0.925) with the actual IBSBW data compared to the mean method (r = 0.887) or the median method (r = 0.921).

Heat stress response in dairy cattle affects milk production, quality, body temperature, and other parameters. Dairy cows will most likely experience increased heat stress with unabated global warming. Elevated temperatures and humidity reduce feed intake, harm reproductive potential， and reduce milk production. Heat stress is more common in high-yielding cows than in low-yielding ones. In addition to reducing milk production, heat stress can also reduce milk quality. During lactation, internal metabolic heat production can further reduce cattle's substances to high temperatures, resulting in altered milk composition and decreased milk yield. Several studies proposed various nutritional strategies such as dietary fats, dietary fibers, microbial diets, mineral substances, vitamins, metal ion buffers, plant extracts, and other anti-stress additives. This review addresses the challenging study on the effects of heat stress on nutritional and fed intake perturbations, milk and components yield, immune system activation, and reproduction parameters. It proves that specific nutritional strategies effectively mitigate the harmful effects of heat stress in dairy cattle.

In tropical developing regions, such as Brazil, animal welfare (AW) has been gaining increasing attention, while stockperson job satisfaction, which is intimately related to AW, is often neglected. This research evaluated the effects of AW training on stockpersons’ attitudes and behaviour towards dairy cows and the impact on cows' fear of humans. Ten dairy farms with pasture-based systems where animal handlers are farm owners or employees were selected from three regions of Sao Paulo, Brazil. The experiment consisted of four stages: 1) Selection of pasture-based dairy farms; 2) First assessment of attitudes, human behaviour, and cows’ flight distance (day one – D1); 3) Pre-assessment of owners' and employees’ AW knowledge, and training (day two – D2); and 4) Final assessment of attitudes, human behaviour, cows’ flight distance, and owners' and employees’ AW knowledge (day three – D3), focusing on the training’s effects on human attitudes and behaviour, and cows’ fear of humans. Among owners and employees, positive attitudes were more often expressed, and negative attitudes were less frequent on day three (D3) after training. Nevertheless, the expression of positive attitudes by farm owners was less common compared to employees. Stockpersons manifested positive behaviour more frequently at D3 than on day one (D1), before training, in contrast to negative behaviour at D1. Taking all cow handling observations together, including those before and after training, the greatest percentage of negative behaviour was at the time of moving the cows from the holding area to the milking stalls (18% of all observed human behaviour), followed by moving cows out of the milking parlour (17%), positioning cows for milking (15%) and placing/removing the milking suction devices (1%). Positive human behaviour usually occurred when moving cows from the holding area to the milking stalls (21%) and during the positioning of cows for milking (19%). After training, cows’ flight distances decreased. In conclusion, the training may have promoted positive human behaviour and reduced the number of fearful cows. Therefore, AW training may positively influence human behaviour, technical expertise, the reduction of fear in cows, and stockpersons' attitudes.

The red panda (Ailurus fulgens) population is decreasing, with less than 10,000 individuals in the wild because of habitat destruction, fragmentation, and illegal hunting. Captive breeding has become an increasingly crucial strategy for conserving endangered species, but efforts to generate self-sustaining populations have failed despite ample resources being allocated. Animals are often stressed in captivity, and it is necessary to examine reproductive behavior relating to the complexity of habitat requirements, dietary preferences, and, in particular, pregnant mothers and their sensitivity to disruptions. Using videography, we observed the reproductive behavior of two red pandas along with other behavioral activities in the Central Zoo, Kathmandu, Nepal. We collected behavioral data from December 2020 to June 2021 using scan and focal sampling. Reproductive behaviors (e.g., scent-marking, allogrooming, chasing, running, aggressiveness, mating, and feeding feces) were observed, along with behaviors like locomotion, climbing, standing, self-grooming, feeding, sleeping, self-play, and stretching. We observed 1–2% of reproductive behavior from total activity. Copulation was attempted on three occasions suggesting reproduction can be successful if animal husbandry is properly managed. We recommend zoo managers further refine strategies for captive breeding endangered species such as red pandas. Successful captive breeding benefits the zoo, and captive-born animals can mitigate extinction in the wild.

The justification for this review article is to understand the position of vegans and those individuals who consume food of animal origin from an unbiased perspective but with a grounding in scientific evidence. This will provide people who eat meat with scientific and ethical arguments to defend their alimentary autonomy in the context of the moral conflict that has emerged in societies regarding the consumption of meat and animal products, which is criticized –sometimes even attacked– by activists, ovolactovegetarians, or vegetarians with alimentary habits that stress ethical and moral respect for animals. These individuals refuse to eat meat and animal products but sometimes show disrespect for those who do. In recent decades, veganism and vegetarianism have reached an apogee in some western societies where they are often considered a healthy option for humans that simultaneously fosters animal and environmental welfare. While those diets may provide numerous benefits, they can also entail health risks by failing to provide balance and necessary dietary supplements. Various researchers concur that they are not appropriate for pregnant women, children, or carnivorous or omnivorous pets. Our review of scientific articles in favor and against dietary regimens that lack protein of animal origin leads to the conclusion that these dietary changes, on their own, do not reduce animal suffering or the contamination generated by the meat, dairy, and poultry industries. Finally, it is important to consider that, despite the popular opinion that vegetarianism and veganism are healthy diet alternatives, the diet must be individualized and well-balanced according to each stage of their life cycle.

Artificial light, as one of the environmental factors, plays a significant role in regulating the synthesis and secretion of hormones related to the coordination of parameters of life, growth, immunity, and reproductive functions of hens. The article aims to study the influence of monochrome light with different wavelengths on the biochemical parameters of hens` blood serum. Four groups of "Hy-Line W-36" crossbred hens were formed. Hens of the 1st group were kept using monochrome light with different wavelength lamps with a wavelength of ~ 460 nm, the 2nd group ~ 600 nm, the 3rd group ~ 630 nm, and the 4th group ~ 650 nm. It was found that the use of light with different wavelengths for keeping hens in cages of multilevel batteries affects hen' biochemical parameters, according to the research results. It was established that when using light with a wavelength of ~ 630 and ~ 650 nm, the indicators of clinical biochemistry of hens' blood serum were within the normal physiological values. Whereas, with the use of light with a wavelength of ~ 600 nm, an increase in the level of glucose, creatinine, total protein, total bilirubin, and phosphorus, a decrease in the ratio of calcium to phosphorus, in the activity of alkaline phosphatase, aspartate aminotransferase, and lactate dehydrogenase, were observed in the hens’ blood serum. The use of light with a wavelength of ~ 460 nm was accompanied by a further increase in the level of glucose, creatinine, total protein, urea, total bilirubin, phosphorus, the activity of alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase, and gamma-glutamyltransferase, a decrease in the ratio of calcium and phosphorus.

This study aimed to evaluate the thermal response of the eyelids and lacrimal gland of the left eye (LETG) through infrared thermography (IRT), cardiorespiratory parameters, and their association with nociception and pain in bitches undergoing elective ovariohysterectomy (OVH) anesthetized with isoflurane and epidural analgesia. Twenty-one healthy bitches of different breeds were randomized into three groups receiving epidural blocks: GL (n=7), lidocaine (2 mg Kg-1); GLF (n=7), lidocaine (2 mg Kg-1) and fentanyl (3 µg Kg-1); and GLM (n=7), lidocaine (2 mg Kg-1) with morphine (0.1 mg Kg-1). IRT and cardiorespiratory parameters were evaluated at baseline (Ebasal), thirty minutes before anesthetic premedication, and at different surgical events: first incision (EInc), ligature and section of the left (ELoV), and right (ERoV) ovarian pedicle, ligature, and re-section of the cervix (EUt), and skin suture (ESut). The assessment of acute pain in the immediate post-operative period was registered at E1h, E2h, and E3h using IRT, the Dynamic Interactive Visual Analogic Scale (DIVAS), and the University of Melbourne Pain Scale (UMPS) scales. The results showed a statistically significant decrease in the lower eyelid surface temperature (LELT) during EInc for GL (32.9°C ± 0.62), in comparison to GLF (34.2°C ± 0.62) and GLM (35.3°C ± 0.62) (P = 0.006). Regarding LETG, a significant increase (P = 0.03) in the IRT of Ebasal (36.8°C ± 0.63) and EInc (36.1°C ± 0.63) for GLM was observed in comparison to the thermographic values for both perioperative events and groups. The GLM showed a significant decrease in IRT values of ERoV at E3h in the upper and lower eyelids (P = 0.03 and P = 0.01, respectively). A progressive and significant reduction of the IRT values of LETG was also recorded in GLM, with differences in ERoV (35.2 °C ± 0.63) (P = 0.02) and E3h (35.3 °C ± 0.63) (P = 0.01). The cardiovascular parameters (SAP, DAP, and MAP) did not differ between treatments, but in GL, there was a significant difference (P = 0.01) during EInc and ESut, compared to Ebasal. In the body temperature, EInc and ESut gradually decreased in all treatment groups (P = 0.01). In conclusion, hemodynamic and cardiorespiratory stability was associated with IRT readings and the absence of nociception. Changes in superficial temperature in the immediate post-operative period were lessened using isoflurane and epidural analgesia of lidocaine alone or in combination with pure opioids. These findings were clinically validated to the DIVAS and UMPS acute pain assessment scales.

Regarding LETG, a significant increase (P = 0.03) in the IRT of Ebasal (36.8°C ± 0.63) and EInc (36.1°C ± 0.63) for GLM was observed in comparison to the thermographic values for both perioperative events and groups. The GLM showed a significant decrease in IRT values of ERoV at E3h in the upper and lower eyelids (P = 0.03 and P = 0.01, respectively). A progressive and significant reduction of the IRT values of LETG was also recorded in GLM, with differences in ERoV (35.2 °C ± 0.63) (P = 0.02) and E3h (35.3 °C ± 0.63) (P = 0.01). The cardiovascular parameters (SAP, DAP, and MAP) did not differ between treatments, but in GL, there was a significant difference (P = 0.01) during EInc and ESut, compared to Ebasal. In the body temperature, EInc and ESut gradually decreased in all treatment groups (P = 0.01). In conclusion, hemodynamic and cardiorespiratory stability was associated with IRT readings and the absence of nociception. Changes in superficial temperature in the immediate post-operative period were lessened using isoflurane and epidural analgesia of lidocaine alone or in combination with pure opioids. These findings were clinically validated to the DIVAS and UMPS acute pain assessment scales.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48088163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the relationship between behavioural activities and sperm parameters in modern and local breeds of Ukrainian boars. Visual observations were conducted on 30 boars, aged 12 and 24 months, with five boars from each of the following breeds: Large White, Landrace, Ukrainian Meat, Pietrain, intrabreed type of Duroc breed of Ukrainian selection "Steppovyi", and the terminal line "Maxter". Behaviours such as rest, movement, feed, and water intake during 24 hours were recorded. Semen samples were manually collected from each boar and evaluated for quantitative and qualitative indicators of sperm quality and fertilizing capacity according to the "Instructions for Artificial Insemination of Pigs", which included parameters such as ejaculate volume, sperm concentration in the ejaculate, percentage of correctly motile spermatozoa, survival of spermatozoa, and fertilizing ability of boars. The study found that certain behavioural activities significantly influenced the qualitative and quantitative indicators of sperm parameters in boars of different breeds. Specifically, time spent on rest and movement, as well as the index of movement activity (at 12 months of age), significantly (P < 0.05) influenced ejaculate volume, sperm concentration, and the percentage of correctly motile spermatozoa. Moreover, the effect of these behavioural acts on ejaculate volume had a curvilinear character. On the other hand, the survival of spermatozoa and fertilizing ability of boars were mainly determined by their time spent on feed and water intake (at 24 months of age), and the relationship detected in this case was asymptotic.

The present study aimed to investigate the effect of milk liquid and powder supplements on piglets’ performance, drinking behavior, and sow back-fat thickness change during the lactation period. There were 4 experimental groups (n = 24), and in the control group (n = 6), the piglets were suckled from the sow. For the supplemental groups (n = 18), milk powder (MP), milk liquid by feeding trough (MLFT), and milk liquid feeding by the bucket (MLFB). There were significant differences in average daily weight gain between day 14 and weaning age for the MP and MLFT (p < 0.05) but not in MLFB (p > 0.05). For approaching to the feeder, there were significantly higher in MP and MLFT groups (p < 0.05). Based on the examination of sow back-fat thickness, the back-fat loss was minimal (p < 0.05) in the MP and MLFT compared to the MLFB and the control. Giving the milk supplement as powder and liquid by feeding trough has increased the average daily gain and body weight of the piglets on day 14th and on weaning day. Moreover, back-fat thickness reduction of sows in the supplemental groups is lower compared to the control group.
