“…Chandra et al [22] reported that RT of KF remained significantly high compared to Sahiwal and Tharparkar cattle during different seasons and the magnitude of increase in RT was higher in KF than Sahiwal and Tharparkar during summer season. Randhawa et al [23] reported that the temperature humidity index (THI) describes the effect of environment on animal's ability to dissipate heat. During drought, the ambient temperature and RH frequently exceed the critical comfort level of THI (72), resulting in elevated body temperature and panting.…”

Aim: The present investigation was undertaken to study the impact of heat stress and hypercapnia on physiological, hematological, and behavioral profile of Tharparkar and Karan Fries (KF) heifers. Materials and Methods:The animals of both the breeds of Tharparkar and KF were exposed at different temperatures and CO 2 levels. Exposure conditions of 25°C, 400 ppm CO 2 level, and 60% relative humidity (RH) were taken as a control condition. The exposure conditions 40°C with two levels of CO 2 500 ppm and 600 ppm with RH 55±5% and exposure conditions 42°C with two levels of CO 2 500 ppm and 600 ppm with RH 55±5% were taken as treatments. The exposure period in each condition was 4 h daily for 5 consecutive days. Results: Physiological responses (respiration rate [RR], pulse rate [PR], and rectal temperature [RT]) were significantly (p<0.01) higher and different during all exposure conditions compared to control condition in both the breeds of cattle. KF heifers had higher RR, PR, and RT than Tharparkar heifers. Hematological parameters, namely, red blood cell, hemoglobin, and packed cell volume were significantly higher and different during all exposure condition than control in both the breeds, whereas no significant changes were observed in total leukocyte count and differential leukocyte count. Blood pH increased with increase in temperature and CO 2 levels and was significantly higher than control conditions. PCO 2 and base excess were significantly (p<0.05) lower, and PO 2 was higher during different exposure conditions than control in both breeds. Restlessness and excitement signs were observed in all the exposure conditions as compared to control condition in both the breeds. Conclusion:Changes in physiological responses, behavioral pattern, and hematological parameters reflect the current functional status of the body system, and it can be used as an index for assessing the adaptation capacity of cattle to predict changes occurring in climate variables due to increasing CO 2 levels and environmental temperature.

“…This fact makes the air temperature in the afternoon to be the origin of a high rectal temperature in the tropics, especially in the summer. Therefore, it can be used to assess the thermal stress level of animals during this period as rectal temperature measurement is often used as an index of physiological adaptability to warm environments because its increase shows that mechanisms of heat release became inefficient (Randhawa, Chhabra, Randhawa, Zahid, & Dhaliwa, 2014). The fact that animals showed a normal RT despite the high BGTHI value shows their efficient mechanisms to maintain homeothermia and that water salinity levels do not affect this balance.…”

The objective was to evaluate the effects of potential use of brackish water as a source for Sindhi heifers on ingestive behavior and physiological and serum parameters. Twenty-four Sindhi heifers were distributed in a completely randomized design with four treatments and six replications, with levels of total dissolved solids (TDS) of 640, 3200, 5760, and 8320 mg/L. Three 24-hour behavioral tests were performed, which were divided into four observation shifts (00:00 to 06:00; 06:00 to 12:00; 12:00 to 18:00 and 18:00 to 00:00) at the beginning, middle, and end of the experiment. The highest values of black globe temperature humidity index and air temperature were observed at 14:00 h, with values of 92.7 and 34.1 °C, respectively. The different levels of TDS did not promote significant differences (P > 0.05) in the variables feed intake, rumination, idling, feeding efficiency as a function of dry matter and neutral detergent fiber intake, rumination efficiency as a function of dry matter and neutral detergent fiber intake, heart rate, rectal and surface temperature, creatinine, and potassium. Among the assessed shifts, feed and water intake showed higher frequencies in the shifts 2 (06-12 h) and 3 (12-18 h) and rumination showed a higher frequency in the shifts 1 (00-06 h) and 4 (18-00 h). The physiological variables presented higher indices during the warmest hours of the day. A linear behavior was observed for the serum sodium level, presenting a average of 134.4 mmol/L. Water containing up to 8,326 mg/L TDS can be used in the watering of Sindhi heifers in short periods in the season of highest water shortage without affecting the ingestive behavior and physiological and serum parameters of the animal.

“…Continental European breeds, such as Charolais, were selected based on their aptitude to produce meat and traction, resulting in animals with greater muscling than other European breeds, especially of British origin, which were selected based on quantitative and qualitative carcass and meat traits (Gregory and Cundiff, 1980). In Zebu breeds, such as Nellore, due to their tolerance to warm climates, natural selection resulted in animals with a thinner (Randhawa et al, 2014), lighter structure, with low muscle and bone mass, and better fat deposition than the Charolais breed (Restle et al, 2002).…”

Heterosis plays an important role on yield and profitability of beef production systems. This study evaluates the morphometrics of purebred Nellore (N) and Charolais (C) animals and of the second (G2) and third (G3) generations of their alternating crosses, regarding the effects of genetic group and heterosis from birth to 365 days of age. The experiment comprised 159 calves (C = 29, N = 22, G2 -3/4C 1/4N = 21, 3/4N 1/4C = 9, G3-5/8C 3/8N = 44 and 5/8N 3/8C = 34). The foreshank girth (FG), thoracic girth (TG), body length (BL), and hip height (HH) were measured after birth, and at 63, 210, and 365 days of age, and the total increases were calculated. The Charolais animals had greater FG, TG, and BL values than Nellore, while the latter had greater HH. For the offspring generations, the predominance of Charolais genes in the genotypes resulted in greater measurements for FG and TG in G2, whereas the predominance of Nellore genes resulted in higher HH values in both generations.The crossbred animals had greater values for all measurements than the purebreds, with more significant differences in FG, TG, and BL compared to Nellore purebreds and in HH compared to Charolais. Charolais animals show higher values for muscularity; while, Nellore animals are taller.Crossbred animals show greater development compared to purebreds, indicating a significant effect of heterosis.
