Sánchez-Castro Milton G. Thomas R. Mark Enns Scott E. Speidel Ricardo Zamorano-Algandar José C. Leyva-Corona Carolina García-Benitez Pablo Luna-Nevárez <p>Summer heat stress in northwest Mexico compromises the physiological thermoregulation capacity and productive performance of lactating Holstein cows, and supplementation of minerals appears to reduce the adverse impact of heat stress in cattle. The objective herein was to evaluate the effects of an injectable mineral supplement containing phosphorus, selenium, potassium, magnesium, and copper on physiological responses, milk production, and milk composition of Holstein cows exposed to heat stress. Sixteen cows were blocked by parity and assigned to one of two treatments (<em>n</em>= 8) using a randomized complete block design: 1) control cows and 2) mineral-treated cows. All cows were exposed to environmental heat stress conditions (i.e., temperature-humidity index = 79.4 ± 4.3 units). No study variable was affected (<em>P</em> ≥ 0.20) by the treatment x sampling day interaction. While the mineral supplement did not affect any physiological variable in the afternoon, this treatment decreased breaths per min (<em>P</em> = 0.01) and most body surface temperatures (<em>P</em> ≤ 0.06; head, shoulder, leg, right-flank, and udder) in the morning. There was no effect (<em>P</em> = 0.37) of the mineral supplementation on milk yield but increased (<em>P</em> ≤ 0.03) the percentages of solids non-fat, protein, lactose, and density in the milk. In conclusion, Holstein cows' physiological thermoregulation and milk composition experiencing summer heat stress were improved by applying an injectable mineral supplement.</p> 2021-09-20T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Influence of climatic conditions on tympanic temperature and milk production in grazing cows 2021-08-05T20:50:27+00:00 Mauricio Velez Terranova Raul Molina Hugo Sanchez Romulo Campos Sandra Perilla <p>The present study aimed to analyze large volumes of tympanic temperature (TT) data to identify its use as a physiological indicator of climatic conditions and its relationship with milk production in grazing cows under tropical lowland conditions. Three dairy farms and 21 multiparous early lactation cows were included in the study. Seven animals were equipped with tympanic temperature wireless sensors within each farm, and permanent information was collected hourly for 22 days on average. Ambient temperature (AT), relative humidity (RH), wind speed (WS), precipitation (PP), and THI information were obtained from meteorological stations located close to each farm. Statistical analyses included Spearman correlations and random coefficient regression models (<em>P</em> &lt; 0.05). TT presented moderate and significant correlations with AT (0.35 to 0.49), SR (0.25 to 0.32), THI (0.35 to 0.49), and RH (-0.35 to -0.49). Climatic variables like AT, PP, SR, and WS were the most contributing factors to TT prediction (R<sup>2</sup> =0.42 to 0.86). Grazing dairy cows in tropical scenarios accumulate heat during the day and dissipate it at nighttime, although higher producing animals deal with more problems to reach thermal homeostasis. Correlations between TT and daily milk production varied according to animal yield; however, higher TT values were related to the most productive cows. The effect of TT on milk production prediction was not conclusive among farms, possibly by animal management or others characteristics of the systems. TT determination through remote sensors allows a reliable diagnosis of the physiological temperature response to climatic conditions.</p> 2021-09-02T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Nest building, dimension, and selection of aromatic and medicinal twigs to repel ectoparasites in the European Turtle dove 2021-07-03T11:45:26+00:00 Ismail Mansouri Driss Ousaaid Wafae Squalli Ikram Douini Mohamed Mounir Abdelbari El Agy Amine Assouguem Hamid Achiban Lahsen El Ghadraoui Mohamed Dakki <p>Studies incorporating the nesting behavior and ecology of parasite disease in the European turtle dove during breeding periods are rare. This research examined nest features and nesting materials in Turtle doves to characterize nest dimensions, build, and incorporate vegetation, mainly aromatic and medicinal plants. In parallel, we estimated the ectoparasite load on chicks to verify an eventual relation between odorant plants and pathogen loads. The study was carried in apple orchards at Okhaja Ait Ayach, Midelt province Morocco, during 2015 and 2016. The obtained results demonstrate that the Turtle dove constructs a medium nest, compared to its body size, using several plant species, including medicinal and aromatic species known for their toxicity against pathogens. The inhibition capacity of nesting materials is reflected in parasite loads since only 8% of chicks were infested with&nbsp;<em>Columbicola columbae&nbsp;</em>and&nbsp;<em>Dermanyssus gallinae</em>. Repellent materials in nests are a successful behavioral strategy for this declining game to protect nestlings against pathogens.</p> 2021-07-03T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Brown Swiss cows are more heat resistant than Holstein cows under hot summer conditions of the continental climate of Ukraine 2021-07-06T13:56:54+00:00 Roman Mylostyvyi Olena Lesnovskay Lina Karlova Olena Khmeleva Olena Кalinichenko Oksana Orishchuk Svitlana Tsap Natalia Begma Nikolay Cherniy Bogdan Gutyj Olena Izhboldina <p>Finding livestock breeds that are resistant to high temperatures may be one of the strategies for mitigating the impact of global climate change on dairy farming. In this investigation, we studied the heat resistance of Holstein (HB) and Brown Swiss (BS) cows on two commercial dairy farms under the hot summer conditions of Ukraine. The physiological response of animals determined heat resistance by measuring rectal temperature (RT) and respiratory rate (RR) in the morning (from 4:00 to 6:00) in comfortable conditions and the afternoon (from 14:00 to 16:00), during heat load. The temperature-humidity index (THI) was used to characterize weather conditions and microclimate in naturally ventilated rooms (NVBs). BS cows were found to be heat resistant. The reaction of HB cows to the heat was manifested by higher growth of RT and RR, and they suffered significant losses in the daily milk yield per cow in the summer. Further research will need to elucidate the biological and genetic mechanisms of the identified breed differences in heat tolerance of dairy cows.</p> 2021-07-31T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Effects of ethanolic extract of the <em>Cleome arabica</em> plant on sexual behavior in Wistar rats 2021-06-11T17:33:13+00:00 Nour El Imene Boublata Sarra Habbachi Fatma Zohra Saadane Abir Bouzar Wafa Habbachi <p>Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 plants used for the treatment of toxicity were screened for their protective effects. Traditional medicinal are globally used and have rapidly grown in economic importance. Intrinsically active compounds are well-known for their antioxidant, anti-tumor, anti-viral, and anti-inflammatory activities. The study was conducted to investigate the effects of the ethanolic extract of <em>C. arabica</em> leaves on sexual behavior in Wistar rats. <em>C. arabica</em>, a medicinal plant with a foul odor, toxic, and has hallucinogenic effects. The experimental study was carried out on white rats (male and female) of the Wistar strain from the Pasteur Institute of Algiers (Kouba, Algeria), weighing between 150 and 200g sexually naive. The animals were raised in polyethylene cages and divided into two groups (n = 10 rats/group), which received a saline solution (male and female control group), 0.20µg/ml of the ethanolic extract of C.arabica leaves for seven days orally (male and female treated group). The sexual behavior test was performed according to three types of crossing. The results of the treated groups showed a significant increase in mating frequency compared to the control group. Overall, the results showed that <em>C. arabica</em> significantly affects sexual behavior. The ethanolic extract of <em>C. arabica</em> increased sexual behavior and orientation activity performance recorded in the treated animals. Thus, this study found that <em>C. arabica</em> has a significant effect on the rats' sexual behavior.</p> 2021-07-13T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Optimization of some environmental and nutritional conditions using microtiter plate for <em>Pseudomonas aeruginosa</em> biofilm formation 2021-07-26T13:46:06+00:00 Shaymaa Fouad Rasheed Al-Khazraji Mohammad Abdul Rahmman Al-Maeni <p>One of the most important virulence factors in <em>Pseudomonas aeruginosa</em> is biofilm formation, as it works as a barrier for entering antibiotics into the bacterial cell. Different environmental and nutritional conditions were used to optimize biofilm formation using microtitre plate assay by <em>P. aeruginosa.</em> The low nutrient level of the medium represented by tryptic soy broth (TSB) was better in biofilm formation than the high nutrient level of the medium with Luria Broth (LB). The optimized condition for biofilm production at room temperature (25 °C) is better than at host temperature (37 °C). Moreover, the staining with 0.1% crystal violet and reading the biofilm with wavelength 360 are considered essential factors in increasing the productivity of biofilm formation in <em>P. aeruginosa</em>. Finally, we highly recommended using these optimized microtitre plate assays to assess biofilm formation in <em>P. aeruginosa</em>.</p> 2021-07-26T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Impact of climatic variability on growth performance of Fogera cattle in Northwestern Ethiopia 2021-07-13T17:51:06+00:00 Michael Abera Mitiku Eshetu Yesihak Yusuf Mummed Fabio Pilla Zewdu Wondifraw <p>This study aimed to assess the impact of climatic variability on the growth performance of the Fogera cattle at Metekel cattle breeding and multiplication ranch. About 15-years of meteorological data were collected from National Meteorological Agency. Then, the heat stress (HS) condition of the ranch location was calculated by the temperature-humidity index (THI). Moreover, all animals born and calves that were weaned from 2005 to 2019 were included in this study. Seasons and years of birth were fitted as predictors, while growth parameters were fitted as response variables. Data were analyzed by least-squares means analysis of variance using R software version 3.5.2 program. Moreover, a multiple linear regression model was also used. The trends in birth weight (BW) and weaning weight (WW) of calves were significantly decreasing along the study period. The result also indicated that the relative humidity and ambient temperature regression coefficient was negative for BW and WW. The Pearson correlation coefficient also indicated there was a negative relationship between growth parameters and climatic variables. When THI increases from 67 to 72, the BW and WW of the calves were decreased by 3.5 and 25 kg, respectively. However, the optimum THI for higher BW and WW was less than or equal to 67. The lower BW and WW of calves observed in this study is due to the cumulative effect of the climate conditions of the study area and herd management practices. Therefore, in any improvement to be made in the ranch, environmental factors should be considered along with necessary amelioration activities.</p> 2021-08-16T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Productive flight activity of bees in the active period in the conditions of Vinnytsia region 2021-07-10T17:44:38+00:00 Olena Razanova Vitaiy Kucheriavy Lyudmyla Tsaruk Halyna Lotka Nadiya Novgorodska <p>The study aimed to identify the relationship between pollen collection, nectar, and seasonal dynamics of the brood of the bee colonies of the Ukrainian bee breed to study their active activity when changing the period of the active season. We compared the collection of nectar and pollen from honey plants of the garden, white acacia, and sunflower. The number of bees bringing pollen and nectar to the hive was recorded. The active work of bees to collect pollen is associated with the work of the uterus to lay eggs and the number of broods in the hives. Bee colonies increase their flight activity by collecting pollen in early spring and summer. By the beginning of the main honey harvest, pollination work is minimized, especially during the flowering of white acacia, and they switch to collecting nectar. Analysis of the results allows us to conclude that bees' daily dynamics that produce pollen increase in the spring to May and June.</p> 2021-08-11T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Behavior of horses kept in different types of stalls in the semiarid region of Minas Gerais, Brazil 2021-07-24T15:16:31+00:00 Maria Dulcinéia da Costa Cinara da Cunha Siqueira Carvalho Wemerson Fábio Gomes Ribas Virgílio Mesquita Gomes Alvimara Felix dos Reis Sara Guedes de Paula Vicente Ribeiro Rocha Junior Ricardo Rodielle Rodrigues Gomes Flávio Pinto Monção <p>The objective of this study was to evaluate the feeding and agonistic behavior of Quarter Horses kept in different types of stalls in the semiarid region of Minas Gerais. A completely randomized design with two treatments (two types of stalls) and seven replicates (seven days of evaluation) was used. Four Quarter Horse mares and four stallions were used per treatment. Behavioral observations were made at 10-minute intervals for 24 hours. The stall environment was characterized by the following variables: air temperature, relative humidity, and black globe temperature for subsequent estimation of the wet-bulb globe temperature. Feeding behavior variables included: time spent eating concentrate and time spent eating roughage (hours), bite rate (bites/min), and the number of daily bites (bites/day). Zinc-roofed stalls had higher air temperatures than clay-roofed stalls and the external environment, averaging 28.2, 27.0, and 27.4 ºC, respectively, while relative humidity was significantly lower in the external environment (65.80%). Horses housed in zinc-roofed stalls had longer feeding times (8.32 h) than animals kept in clay-roofed stalls (7.22 h). Approximately 94% of the total feeding time was spent eating roughage and 73% of the time was spent resting and walking, regardless of the covering type. Although environmental variables showed thermal discomfort, the roofing material did not alter the feeding behavior of stabled horses in the semiarid region of Minas Gerais, suggesting an adaptation to the studied conditions. The feeding frequency should be increased to avoid a long resting time.</p> 2021-09-05T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Elevated temperature-humidity index induces physiological, blood and milk alterations in Holstein cows in a more pronounced manner than in ½ and ¾ Holstein × Gir 2021-08-05T17:36:02+00:00 Marcelo Tempel Stumpf Giovani Jacob Kolling Vivian Fischer Darlene dos Santos Daltro Evelyn Priscila Munchen Alfonzo Vanessa Calderaro Dalcin Laila Talarico Dias Marcos Vinicius Gualberto Barbosa da Silva Vanessa Peripolli Concepta Margaret McManus <p><em>Bos taurus taurus </em>and <em>Bos taurus indicus </em>cattle subspecies present different capabilities in coping with situations of elevated temperatures, the latter being more tolerant to heat stress. Thus, some breeding programs crossed these subspecies to produce a high producing yet heat-tolerant breed (Girolando). Nineteen Holstein (H100) and 19 Girolando cows [(½ Holstein x Gir (H50) and ¾ Holstein x Gir (H75)] with similar milk production were used in a six-day experiment to evaluate the consequences of heat stress due to shade deprivation on their physiological, blood and milk traits. Cows were exposed to a non-shaded environment between morning (06:00h; GMT -3:00) and evening milking (14:30h; GMT -3:00) with access to water <em>ad libitum</em>. Procedures were conducted before morning and evening milkings. Physiological parameters related to mechanisms of heat dissipation were measured, as well as the milk composition. Blood traits were evaluated. Temperature-humidity index (THI) was calculated. Statistical procedures included analysis of variance, correlation and principal factors. THI was elevated during the entire trial and negatively impacted physiological, milk and blood parameters in H100, H75 and H50. Alterations in physiology, milk stability, milk composition and blood traits were more pronounced in H100. Holstein cows presented changes in physiological parameters in a more pronounced manner and in some milk and blood traits related to the reduced capability of this breed in dealing with elevated THI. The similarity in milk production levels excludes this parameter as a justification for differences in heat tolerance, with genetic composition being the main reason for this results.</p> 2021-09-10T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology
