Two hundred fifty adult Awassi and crossbred sheep (Arabi x Hamadani) were used. Three times weekly, ten times for each breed, vital signs, including heart rate (HR), respiratory rate (RR), rectal temperature (RT), and skin temperature (ST), were recorded. The heat tolerance indices (HT) and the heat tolerance coefficient (HTC) were evaluated. SAS was used to conduct the analyses, which included variance and correlation analyses. Awassi had a significantly higher (P < 0.01) RR than crossbred in the summer under low stress conditions. Awassi HR was significantly lower than that of crossbred sheep, which recorded the highest value in summer. There were no significant differences in RT, HT and HTC between Awassi and crossbred sheep. MCH, MCV, and RDW increased substantially in Awassi sheep exposed to colder winter temperatures. In summer, Awassi's liver enzyme and triglyceride levels significantly decreased, while albumin levels increased. Both HT and HTC had negative correlations with RR. Therefore, it can be concluded that the Awassi breed is equally adapted to the region's hot and arid climate.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139256636","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}

High variation has been observed in superovulation (SPO) and embryo flush recovery, which appear to be influenced by donor cow genetics. Then, the objective was to identify single nucleotide polymorphisms (SNPs) from the genes IGF1 and IGF1R associated with reproductive traits related to SPO response in dairy cows raised in a semiarid region. Sixty-four Holstein cows were subjected to SPO, artificial insemination, and nonsurgical embryo collection. Individual blood samples were collected and used to genotype 13 SNPs from the genes IGF1 and IGF1R. Additional blood samples were collected to measure anti-Mullerian hormone (AMH) concentrations. Ovarian and embryo traits related to SPO response were evaluated. A mixed-effects model was used to identify associations between SNPs and SPO-related traits. A regression model was implemented to calculate allele substitution effects. From 13 SNPs, the SNP rs109763947 in the gene IGF1 and the SNPs rs110343126 and rs208140993 in the gene IGF1R were predictors for six traits evaluated in superovulated cows. The most favorable genotypes for these SNPs were CC, AA and GG, respectively. A linear trend was detected, suggesting an additive effect of the genes. Moreover, all traits evaluated in the current study improved as the number of favorable SNP genotypes increased, confirming a positive contribution of the SNP genes. In conclusion, three SNPs in the genes IGF1 and IGF1R were marker predictors for reproductive traits related to SPO response and embryo production in Holstein cows managed in a semiarid region.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323816","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}

Sixteen Nellore bulls were examined in Tibau city, Northeast Brazil (5°52ʹ South, 37°20ʹ West, and 37 m above sea level) over four nonconsecutive days, with data collection taking place at one-hour intervals between 7:00 am and 5:00 pm. Four animals were analyzed each day and kept exposed to the sun for the duration of the study. The average age of the animals was three years, and their average body weight was 650±32 kg. The meteorological station measured air temperature (°C), relative humidity (%), solar radiation (W.m-2), and black globe temperatures (°C) every minute, while a digital anemometer thermohygrometer measured wind speed (m.s-1) at the same time. Respiratory rate (breaths.min-1), expired air temperature (°C), rectal temperature (°C), and body surface temperature (°C) were measured as physiological variables. Biophysical equations were used to estimate the sensible and latent heat transfer mechanisms (W.m-2). The air temperature ranged from 28.5 to 32.5°C, and direct solar radiation was between 21 and 891 W.m-². Between 11:00 am and 1:00 pm, the study observed heat gain through longwave radiation, which reached an average of 250 W.m-2, with a significant increase (P < 0.05) in respiratory rate and body surface temperature during this time. Convection was significant in heat dissipation, particularly when the wind speed was increased from 11:00 am. However, latent heat loss mechanisms were more effective in losing excess body heat under total sun exposure, despite the positive effect of convection. The study findings showed that Nellore bulls maintained their body temperature within a narrow range even when exposed to high solar radiation, thus demonstrating the efficiency of physiological and biophysical mechanisms during times of greater thermal challenge.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44783847","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}

They respond to disturbances by altering their density and behaviour. Therefore, many of them are used as bioindicator species of human disturbance. Here, we pioneer the use of fiddler crabs to examine whether they alter their behaviour under human disturbance. Male fiddler crabs possess one large claw used for courting (waving) and fighting, and one small feeding claw, whereas females have two feeding claws. They show several surface activities. This study investigates (1) the effects of human disturbance on density and sex-ratio, and (2) the effects of human disturbance, and sex on behavioural time allocations in Austruca annulipes. Their density, sex-ratio, and time allocations were investigated in human-disturbed area (DA) and nondisturbed area (NDA). They showed feeding, feeding and walking, walking, running, standing/vigilance, inside burrows, burrowing, grooming, fighting, and waving. The results showed that crab density was higher and the sex ratio was more male biased in NDA than in DA. Human disturbance and sex affected time allocations but their interaction had no effect. Crabs in DA spent more time running, standing, and inside burrows but less time walking, burrowing, fighting, and waving than crabs in NDA. Between sexes, males spent more time standing, burrowing, grooming, and fighting but less time feeding, and walking than females. This indicates that human disturbances force the crabs to spend more time on anti-predator and escape behavior (standing/vigilance, running, inside burrows) rather than courting (waving) and constructing burrows (mating/breeding sites), which are important for breeding.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47638384","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}

Twenty-five (25) articles published contained at least data on feed intake, lactation performance or milk production parameters, rumen fermentation or digestibility, and rumen microbiota measured for experiments involving dairy animals have been selected. Microsoft Excel performed data extraction and organization, and statistical analysis was performed using SPSS. Few studies have observed a negative impact of the LY on the FI (8%), LP (12%), RF (4%), and RM (8%), but the majority of the selected studies reported a positive impact of adding LY (FI: 36%, LP: 52%, RF: 52% and RM: 40%). Cows supplemented with LY showed a marginal decrease in feeding rate; min/d (0.13 vs. 0.14; p=0.65), interval between meals; min (142.1 vs. 1603, p=0.09), meal size; kg of DM/meal (3.4 vs. 3.8, p=0.09), meal duration; min/meal (32.5 vs.35.3, p=0.39), lying boots; no/d (9.5 vs. 9.6, p=0.83), eating boot; bout/day (80.7 vs.8.26, p=0.24), and lying time; min/d (671.1 vs. 697.5, p=0.51). However, LY increases feeding duration; min/d (232.0 vs.226.6, p=0.65), meal frequency; meal/d (9.0 vs.7.8, p=0.07), rumination; min/d (570.3 vs. 344.9, 344.9, p=0.08), and meal criterion with significance; min (20.0 vs. 25.8, p=0.04).

However, it enabled a higher average ruminal Fermentation (p=.005) and microbiota (p=.003). Furthermore, the timing of live yeast culture before calving could influence the performance and ruminal parameters, especially the microbiomes (p=0.006).

In this study we determine bee species visiting watermelon flowers, their daily visits and the resource they forage during 84 observation days on crops in Los Santos, Panama. Native bees, especially stingless bees represented most of the visits, so they probably play a very important role on the pollination of the crops within the zone. The most frequent bee species visiting flowers were N. perilampoides (58.7%), A. mellifera (23%), and P. peckolti (4%). Most of the bees foraged nectar, with very similar numbers between staminate and pistillate flowers. Honeybees dedicated almost half of their visits (47.7%) for pollen collection, and made most of their daily visits between 7:00 and 8:00 hours, whereas stingless bees visits picked up between 8:00 and 9:00 hours. Nectar visits were shorter than pollen visits, and overall, honeybees made the shortest visits to watermelon flowers. We found significant differences in the daily foraging patterns between bee species foraging for resources during the 84 observation period (Friedman P<0.05). We also found bee characteristics (size, color and sociability) and hour of the day significantly influenced flower visits for resources (GLMM P<0.05).
