Abstract

The main objective of this study was to investigate genetic and phenotypic trends for fertility traits in Holstein dairy population under warm and temperate climate. Fertility traits were: success in first service, gestation length, number of inseminations, insemination outcome, calving interval, calving birth weight and days open. The edited data set included up to 23,402 records from 9,486 cows. The mean and standard deviation for fertility traits were 0.32±0.003, 278.2±5.58, 2.73±1.94, 0.31±0.001, 415.99±79.62, 40.4±6.08 and 140.36±76.16 for success in first service, gestation length, number of inseminations, insemination outcome, calving interval, calving birth weight and days open, respectively. In general, there were decreasing genetic trends for all traits over the years. On the other hand, there were decreasing phenotypic trend for days open, calving interval, gestation length, number of inseminations and calving birth weight, but estimates of phenotypic trends were positive for success in first service and insemination outcome over the years. It was concluded decreased trend for days open, calving interval, gestation length, number of inseminations and calving birth weight and increased trend for success in first service and insemination outcome traits over time indicated that Holstein dairy producers in warm and temperate climate were successful in managing and improving in nutrition during 1999 to 2013.

Abstract

Feed sorting is a natural behavior of cattle that can result in inconsistencies in the nutritive value of the diet. Twenty-four non-castrated F1 Red Norte × Nelore males with an average initial body weight of 439.8 ± 59.6 kg and 21.7± 2.7 months of age were distributed in three experimental groups, and housed either in individual (12 animals) or collective pens (12 animals in three collective pens) at the Cattle Research and Education Center of the Instituto Federal de Educação, Ciência e Tecnologia Goiano (Campus Iporá). The experiment lasted 84 days (14 days of adaptation and 70 days for data collection). Animals were fed diets containing sugar cane in natura (CI), sugar cane silage (SC) or corn silage (CS) as sources of forage. Feed sorting was determined every 14 days at 4, 10, and 24 hours postfeeding using a three-screen and a bottom pan (Penn State Particle Separator) to yield long (>19 mm), medium (<19, >8 mm), short (<8, >1.18 mm) and fine (<1.18 mm) particles. There was no effect (P>0.05) of source of forage on feed sorting for long, medium, and short particles. CS increased (P<0.05) sorting against fine particles compared with CI and SC. There was no response (P>0.05) of type of housing on feed sorting. The sources of forage evaluated in this study resulted in preferential consumption for long and medium particles, which may be beneficial for rumen health.

Abstract

Over the years with changes in both production and marketing aspects of the operation of goats and sheep has been highlighted and is widespread throughout the world. The sheep and goat production systems are affected by several restrictive elements that can compromise their development, among which stands out the adverse weather conditions that contribute to the reduction of the herd productivity. In conditions of thermal stress, the animals begin a series of mechanisms regulated by hormones and coordinated by the nervous system and the endocrine system. In this context, the objective was to make a literature review on hormone physiology in control of heat stress in sheep and goats. Hormonal changes detected in animals under heat stress affects both their productive performance as the reproductive, predisposing the onset of diseases, stunted growth or reproductive harm. Changes in behavior are the first visible signs triggered by hormonal changes due to thermal stress.

Abstract

The hypothesis in this study was that calf birth weight (CBW) would effect on cow's milk production. Data were collected from two commercial dairy milking 15,000 Holsteins in central region of Iran with desert climate from 2006 to 2012. Animals were enrolled at parturition until 7,737 calvings were available for analysis. Data consisted of on-farm measurements of calf birth weight and milk production, and data were analyzed using a multivariable regression model. Independent variables were parity, herdyear-season, calving interval, calving age, retained placenta, days open, dry period length, days in milk, linear and quadratic CBW. The mean CBW was 40.84 ± 4.9 kg (SD) with a range of 20 to 60 kg. There was a trend for milk305 based on calf birth weight, i.e., the amount of milk305 of dam was significantly dependent on that weight of calf was born (P < 0.01). Cows with CBW between 20 and 25 kg had the lowest of milk production. By increasing of CBW range up to 40 and 45 kg, the trend of milk production increased and then decreasing trend observed. In conclusion, calf birth weight could be considered as an important trait in dairy cattle breeding programs in desert climate.

Abstract

This study analyzed sun exposure, substrate type selected, and various behaviors exhibited by the lizard Tropidurus during thermoregulation. Observation entailed thirty days in an urbanized area of Centro de Biociências/ Universidade Federal do Rio Grande do Norte. Their behavior was recorded using a scan sampling route and an instantaneous record method at three different time intervals (9am to 10am, 12am to 1pm, and 3pm to 4pm). Significant differences were seen with sun exposure (p = 0.027), with most lizards remaining in shadowed areas, where the animals preferentially remained standing (p < 0.001). We were also able to observe more lizards in the following substrates: tile, wall, rocks, and bricks (p < 0.001). In addition, the animals were in these substrates more frequently from 12am to 1pm (p = 0.004).

Abstract

This study was designed to evaluate the effect of different levels of metabolizable energy and crude protein on the respiratory rate and the rectal and surface temperatures of 360 European quail (Coturnix coturnix coturnix) raised on the Brazilian semiarid. The animals were distributed in a completely randomized design with a 3 per 2 factorial arrangement consisting of three protein levels (20, 21 and 22%) and two energy levels (3050 and 3150 kcal/kg). We measured the physiological parameters of the quail at 42 days of age. The average rectal temperature noted in this experiment was 41.8°C, which was within the normal range. A significant effect (P <0.05) was verified at the levels of 21 and 22% of crude protein and 3150 kcal/kg. We found that the animals presented the highest respiratory rate in this setting, which is evidence that the panting mechanism results in maintaining thermal homeostasis. The surface temperature of the animals was lower for the 3050 kcal/kg diets. Levels of 21 and 22% of crude protein and 3150 kcal/kg of metabolizable energy were associated with the largest weight gain and the best feed conversion.

Abstract

Purpose of this study was to develop an early warning system for heat stress in cattle. For this purpose, total of 8 lactating cattle (4 Holstein of which 2 high and 2 low producing, 4 Brown Swiss of which 2 high and 2 low producing) which were raised at Dalaman branch of Agricultural Enterprises Directorate of Turkey were used. Before starting the experiment, adjustment time was given to the cattle to get used to human presence. After animals were accustomed to the human presence, researcher positioned herself in a shaded area where cattle came for shade seeking and skin temperature of cattle was read by infrared thermometer and also rectal temperature was read by using rectal probe. Temperature readings were taken at 10:00, 13:00 and 16:00. Study started on July 16 and lasted until August 16 when most of the heat stress is observed. Panting score of the animals were also recorded. Results showed that panting score increased as skin surface temperature increased. Rectal temperature also increased with panting score. Holstein cattle tended to have higher panting score than Brown Swiss cattle. Results showed that measuring skin surface temperature of cattle by infrared thermometer and observing panting scores could be used to early warn heat stress in cattle.

Abstract

The objective of this research was to evaluate the adaptive behavior of Girolando cows to the Piauí semiarid region. Breed data from 10 cows were used to study correlations between the physiological thermoregulatory characteristics and meteorological variables in the morning and afternoon shifts of the dry and rainy seasons of 2011 and 2012. The meteorological variables were: air temperature (TA), humidity (AU), globe temperature, and humidity index (BGT). The physiological responses of animals to the environment were: respiratory rate (RR), rectal temperature (RT), sweating rate (SR), and heart rate (HR). Despite the significant differences in TA and AU (P<0.05) in the morning and afternoon shifts in the two considered stations, only FR showed a significant response to weather changes between shifts. TR and TS did not significantly differ between the shifts in either season (P>0.05). TA, in relation to shifts, had a high positive correlation (0.85), and this high correlation reflects the high temperatures reported, 7.07 and 7.58 °C, in the dry and rainy seasons, respectively. Despite the significant daily weather variation, the responses obtained for the physiological variables of Girolando cows during lactation suggest a good adaptation of these animals to the climate of the semiarid Piauí.

Abstract

In order to evaluate the chemical composition and pH of chicken meat subjected to heat stress during the preslaughter rest time, an experiment was conducted in a slaughterhouse. Twenty-five birds were randomly selected and housed in rooms without air conditioning for a 3-hour period, with an average temperature of 33°C and relative humidity of 83%. After slaughter, the carcasses were deboned and prime cuts were chilled (between 0 and 4 °C) for 24 hours for analysis of moisture levels, protein, fat, ash, and pH. The humidity values were 72.80, 71.47, and 70.30%, protein values were 16.81, 14.90, and 15.10%, lipid values were 0.78, 3.30, and 5.80%, ash values were 0.81, 0.88, and 0.89%, and pH values were 5.30, 6.10, and 6.54 for breast, thigh, and drumstick, respectively. Heat stress for 3 hours before slaughter led to changes in the chemical composition and pH of the chicken, which establishes an anomaly in the flesh of the PSE type (pale, soft, and exudative). It is evident that pre-slaughter management is important to ensure animal welfare and consequently high meat quality.

Abstract

The objective of this study was to compare the behavior of sheep in different pastures, checking for possible differences in time spent grazing, leisure, and the number of bites of animals. 10 sheep Santa Inês were used, at the age of two years, with an average weight of 25.25 ± 2.65 kg. The experimental design was completely randomized with two treatments (Andropogon gayanus pastures and Cynodon dactylon cv. Vaquero) and five replicates per treatment. The trial lasted five days. Two evaluations were performed with duration of 24 hours each, for a day and the average of the two assessments was used in the statistical analysis. It may be noted that as the number of bits, the highest peak occurred in the early hours of the morning (22.16 bites per minute). Daily grazing time was higher (P <0.05) for grazing Cynodon dactylon cv. Vaquero (14.76 hours). For the time in daily idleness was observed the highest values for the pasture of Andropogon gayanus (12.06 hours). We conclude that the sheep had higher acceptability and grazing activity in Cynodon dacytlon cv. Vaquero pasture.

Abstract

An ethogram was prepared to characterize and describe the behavior of the prawn Macrobrachium rosenbergii in the laboratory so that its behavior would foreground in-depth analysis of the species´s culture. Sixty prawns were observed during 30 days through the ad libitum method, featuring one-hour continuous reports, at 07:00- 08:00; 08:30-09:30; 10:00-11:00; 11:30-12:30; 13:00-14:00; 14:30-15:30; 16:00-17:00; 17:30-18:30. M. rosenbergii developed several behavioral activities with 28 categories and grouped in activity classes, such as, maintenance, locomotion, feeding and agonism. Characterization, description and understanding of the behavioral repertoire of M. rosenbergii through methodologies and observation tools typical of behavioral studies are an important step towards the improvement of technical management and welfare of the animal in captivity.

Abstract

A diversidade de variáveis climáticas é necessário estabelecer o nível de conforto. Assim, o uso de sistemas inteligentes podem ajudar a obter um valor único que expressa a condição de que o animal está em. Este trabalho desenvolve um sistema fuzzy para a obtenção de um índice de conforto para zebu e elaborar zonas bioclimáticas para bovinos de corte. O modelo foi desenvolvido no âmbito de um MATLAB ® 8.5 ambiente através do toolbox fuzzy para prever o índice de conforto térmico (ICTZ) a partir das variáveis de entrada: entalpia específica (H, kJ.kg ar seco -1 ) e velocidade do vento (Vv, ms -1 ). Foi utilizada uma dados história de 30 anos de 156 estações com dados médios mensais. Os valores ICTZ obtidos para cada estação foram interpolados por krigagem ordinária e, em seguida, classificadas em quatro condições: perigo, alerta, desconforto e conforto. A região Norte apresentou áreas de alerta durante todo o ano. O país inteiro apresentada a condição de desconforto, exceto para o inverno. Portanto, o uso de sistemas inteligentes se tornou uma grande ferramenta para a obtenção de ICTZ e para a elaboração de zonas bioclimáticas.

Abstract

The animals behave as a thermodynamic system complex, which remains all the time exchanging energy with the environment. In this context, the body temperature of bees considerably accompanies variations in ambient temperature, and the performance of most of its activity is largely affected by air temperature. When these individuals are exposed to temperatures above or below the optimum range for the species during its pupal stage, these, when they survive, have morphological deficiencies, physiological or behavioral as adults. These insects use physiological activities such as internal temperature control mechanisms of the nest. Social insects like honey bees demonstrate certain thermoregulatory ability to nest in which they live, known as the colonial endotherm. This strategy has an interesting feature, which the animals are endothermic when performing motor and ectothermic during inactivity. The meliponines (stingless bees) are highly social bees, working together to maintain the colony, keeping almost constant the temperature throughout the year. The mechanisms of thermoregulation these animals are called passive thermoregulation, it is due solely to the construction of involucre and nesting (honeycomb structures) and not the motor activities of individuals. Therefore, in most species of stingless bees, with rare exceptions, are the only mechanisms that they have to termorregularem. Maintaining a constant temperature is critical for normal growth and development of the larval and pupal stages. It is known that the brood combs also contribute to colonial thermoregulation through its thermogenesis, and larvae and pupae more mature have higher heat input to the brood comb along its development.

Abstract

This study aimed to evaluate the biophysical responses of Santa Inês ewes and crossbred Santa InêsDorper ewes in a hot environment. Physiological parameters were measured: rectal temperature, respiratory rate, coat surface temperature, skin surface temperature, and heart rate. Biophysical parameters were also calculated: heat exchanges by cutaneous convection and radiation, as well as heat storage and thermal conduction in fleece. Throughout the collection period, meteorological variables were similarly monitored. The statistical design was completely randomized in a factorial 2 x 2 (two genotypes and two shifts). According to meteorological variables, the afternoon shift introduced itself with greater heat stress compared with the morning shift. The effect of interaction between genotypes and shifts for respiratory rate, rectal temperature, skin surface temperature, and hair coat surface temperature showed that genotypes exhibit different physiological behavior under similar heat stress situations. Heart rate had the effect of two sources of variation. As for the biophysical parameters, radiation and conduction exchanges in fleece presenting with the shift effect. Heat storage was slightly higher in Santa Inês ewes than in their crossbred Santa Inês-Dorper ewes. It was therefore concluded that crossbred ewes use physiological mechanisms more vigorously to perform heat exchanges, similar to Santa Inês ewes, which have become more adapted to a hot environment.

Abstract

The understanding of feeding behavior may be useful to evaluate the performance of animals fed different diets. Twenty-four non-castrated Red Norte × Nelore males with an average initial body weight of 439.8 ± 59.6 kg and 21.7 ± 2.7 months of age were distributed in three experimental groups, and housed in individual (twelve animals) or collective pens (twelve animals in three collective pens) at the Dairy and Beef Research and Education Center of the Instituto Federal Goiano (Iporá Campus). The experiment lasted 84 days (14 of adaptation and 70 days for data collection). Animals were fed diets containing sugar cane in natura (CI), sugar cane silage (SCS) or corn silage (CS) as sources of forage. Feeding behavior was determined every 14 days for one-hour intervals beginning at 0, 1, 5, and 9 hours post-feeding. Eating, resting and rumination activities were monitored for three-minute intervals through visual observations from individual animals. Time spent with eating was greater (P<0.05) for CS (21.8 ± 1.2 minutes/hour) and time spent with resting was greater (P<0.05) for CI and SCS (38.8 and 36.5 ± 1.5 minutes/hour, respectively). Animals housed individually increased (P<0.05) time spent with both eating (19.7 ± 1.0 minutes/hour) and rumination (8.2 ± 0.6 minutes/hour), while time spent with resting was greater (P<0.05) for the collective pen-housing (38.9±1.2 minutes/hour). Corn silage can be recommended for beef cattle feeding in feedlot system due to an increased time spent with eating.
