The objective was to evaluate the effect of the season on the sexual behavior patterns adopted by Morada Nova sheep in the Brazilian semiarid region. A total of 55 and 59 female sheep were used in the rainy and dry seasons, respectively, attended by four males of the same breed in rotation. The females identified in oestrus were released in a pasture, together with the breeder of the day for each season, and aspects of sexual behavior were measured for an uninterrupted period of 11 hours/day. Assuming a negative binomial distribution, the behavioral frequencies were subjected to deviation analysis and compared using the chi-square. Heading in the male was observed more frequently during the rainy season (0.12) and shifts with higher temperatures; the turn of the head in relation to the man was observed more frequently during the dry season (2.49). The interactions between seasons and shifts significantly affected the following behaviors: sniffing the male, sniffing the male's urogenital region, wagging the tail, lifting the tail, and urinating. Behavioral variables were influenced by the season. Morada Nova sheep reduce their water intake and grazing time to engage more efficiently in reproductive activities, thus demonstrating an ability to adapt to the Caatinga.

This study was carried out to investigate the impact of times of day on the behavior of Japanese quail concerning managerial modifications systems. A total of 120 one-day-old quail chicks were used in this study. 60 chicks were housed in cage systems; distributed into 3 subgroups (20 birds on each), a normal cage group, a cage with cover as wire floor with plastic cover from the top and third cage group “Edinburg modification cage”, as a normal cage except that the front portion has dust bather filled with washed builder sand or fine sawdust. The other floor managerial modifications included 60 birds distributed into three subgroups. The first-floor group was considered “normal”, as 20 birds were housed using an 80×50 floor system with 5cm or l0cm dry, clean soft sawdust sprinkling with slaked lime, the second-floor group was named “A grill group”. The feed was offered to the quail in a plastic feeder covered with the grill to reduce feed wastage and the third-floor group offered feed to the quail in a longitudinal constructed feeder with six holes separated by wire. Data were analyzed using two-way ANOVA, where two factors affect the behavior of quails and from our study, we suggested that there were non-significant differences in the ingestive behavior of quail regarding the daylight effect. Most standing frequencies were conducted midday at most managerial modifications. Crouching time also increased in the early morning with the normal floor group and constructed feeder. We conclude that various times of the day and managerial modifications greatly alter maintenance behavior in most quail chicks. Abnormal behavior was comparatively higher in the morning.

This study investigated spatial and temporal variations on the coexistence of Aedes aegypti , Aedes albopictus , and Culex larvae in five subdistricts in Nakhon Si Thammarat, Thailand. We tested two main hypotheses on the spatial and temporal coexistence of mosquito larvae: (1) condition-specific competition and (2) spatial variation among the five subdistricts. We compared the number of positive houses, positive containers, mosquito coexistence during both the wet and dry seasons. The results showed that from a total of 1,072 positive containers collected in both seasons, Ae. albopictus larvae were found in the highest number of containers (745 containers), followed by containers with Ae. aegypti larvae (283 containers) and containers with Culex larvae (254 containers). During the wet season, there were higher numbers of positive houses, positive containers, and containers with only Ae. albopictus larvae than during the dry season. On the other hand, during the dry season when the water containers were very scarce, there were higher numbers of containers with Culex larvae, and containers held more than one type of mosquito larvae. This indicates that both temporal and spatial variations may contribute to the local coexistence of Aedes and Culex mosquito larvae species in Lansaka District areas in Thailand.

Locomotion can affect the performance (amount) of play behavior in marmosets due to high metabolic costs for primates. In addition, climatic conditions are known to limit the daily activities of marmosets. This study investigates the behavior of social play in wild marmosets and some limitations related to locomotion activities, daily travel and the seasonality of play. Two wild groups were observed with the focal method during the dry and wet seasons and all occurrences of play and locomotion were recorded. Adults played significantly less than juveniles, which played more than infants, and infants, more than the adults did. The reproductive couples played minimally. There was not a relationship between the distance traveled and the mean frequency of play. Nevertheless, all the age categories played significantly more in the wet season than the dry season. The independence to move and forage can explain higher play behavior of juveniles in relation to the infants. The adults and the reproductive couples, have higher energy costs in the group activities, such reproduction, compared to other age class, limiting their amount of play in relation to the juveniles and infants. We conclude that play behavior of juveniles black-tufted marmosets, does could not be impacted by daily locomotion unequivocally, but adults and infants, otherwise, are limited by other energetic costs and dependence to locomotion, respectively.

A study was conducted to assess the cumulative effects of combined stresses (heat and nutritional) on physiological adaptability, blood biochemical and endocrine responses in Malpura rams. The study was conducted for a period of 45 days. Twenty eight adult Malpura rams (average BW 66.0 Kg) were used in the present study. The rams were divided into four groups viz., CON (n=7; control), HS (n=7; heat stress), NS (n=7; nutritional stress) and CS (n=7; combined stress). The animals were stall fed with a diet consisting of 60% roughage and 40% concentrate. The CON and HS ewes were provided with ad libitum feeding while NS and CS rams were provided with restricted feed (30% intake of GI ewes) to induce nutritional stress. The HS and NS rams were kept in climatic chamber @ 42oC and 55% RH for six hours a day between 10:00 hr to 16:00 hr to induce heat stress. The parameters studied were respiration rate (RR), pulse rate (PR), rectal temperature (RT), scrotal volume, sweating rate scrotum, sweating rate skin, haemoglobin (Hb) and packed cell volume (PCV), plasma cortisol, T3 (tri-iodo-thyronine), and T4 (thyroxin) level. Combined stresses significantly (P<0.01) influenced all adaptive parameters studied. The study shows that Malpura rams possess the adaptive capability to two stresses simultaneously. This is evident from the nonsignificant changes in RR, RT, sweating rate of scrotum and skin and Hb concentration between HS and CS groups. Further, the capability to adjust the cortisol level to minimum possible increase to elicit the heat stress relieving effects also proves the superior adaptive capability of Malpura rams to the effects of combined stresses.

Tolerance to heat stress is worth noting considering the constant increase in the ambient temperature and high productivity that elevates the likelihood of heat stress in the dairy herd. Besides exposure to hot temperatures, increase in performance of dairy cows is positively related to heat load which results in heat stress. This necessitates the need to incorporate heat tolerance in the breeding objectives. Measuring heat tolerance is still a challenge and might be complex to assess in the dairy herd. Through regressing phenotypic performance of temperature–humidity index (THI), heat tolerance can be assessed. However, the use of the same THI across region might not be effective due to the differences within and among breeds in either same or different herds. The reason being the differing cow’s (Bos taurus) adaptive and productive response to increasing THI value across different areas. There is vast information about the THI values from the tropics and the temperate regions, however, there is still a gap for THI values for semi and arid places under the pasture-based system. Understanding the coping strategies by the dairy cow to heat stress is important. Various studies have outlined much on the coping strategies but there is still a need to relate the homeostatic and acclimation responses to tolerance to heat stress. This review focusses on discussing the heat stress coping strategies in relation to heat stress tolerance and the ways of assessment in a dairy herd.

The aim of this study was to evaluate the behavioral and physiological responses of dairy cows and their interaction with the milker in two types of milking systems. The experiment was conducted in two farms, in the Coração de Jesus city, Brazil, where the surface temperature (TS, °C), rectal temperature (TR, °C), respiratory rate (RR, breaths.min ) and heart rate (HR, beats.min) of 44 crossbred cows during the morning shift on twelve days of data collection at each farm. It was monitored the meteorological variables: the black globe temperature (TGN, °C), air temperature (TAR, °C), relative humidity (RH, %) and wind speed (V, m.s). Observations about human behavior, negative patterns (tapping, yelling, and pushing) and positive patterns (talking, groping, and naming) were made without people being aware of their nature. The behavioral data observed in the animals were: vocalization (VOC), defecation (DEF), micturition (MIC) and movement (MOV) and milking time (TOR) was also recorded. The physiological variables were significant among farms, except heart rate. The talking, naming, pushing and shouting actions were not significant, only groping and hitting. The behavior occurrences VOC, MIC, and MOV of cows were low. The TO presented a positive correlation (P <0.01) with TS, TR, and HR and negative correlation (P <0.01) with RR. Under the conditions of this experiment, the type of milking system influenced the physiological responses. The milking system of type "bucket at the bottom" provided greater contact between the milker and the cow, leading to a greater negative interaction reflected by the defecation behavior.

The milking system of type \"bucket at the bottom\" provided greater contact between the milker and the cow, leading to a greater negative interaction reflected by the defecation behavior.","PeriodicalId":37772,"journal":{"name":"Journal of Animal Behaviour and Biometeorology","volume":"1 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69769630","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}
