Objective: Since December 2019, the COVID-19 pandemic has posed a substantial threat with its associated high mortality, infection, and risk of psychological stress. A large number of students are affected because of a prolonged break from academic activities and staying at home. The focus of this study is to understand the stress levels of Indian students, any psychological imbalances, and their major hurdles during the COVID-19 lockdown., Methods: Using a snowball sampling method, an online survey of the Perceived Stress Scale (PSS) was conducted on students across India. Along with their demographic details, the participants also reported their study patterns and challenges during their confinement period. The statistical scores for the responses were calculated and the demographic variables analysed. The levels indicated by the PSS were compared, and variance and regression analyses were performed., Results: We observed that students were generally stressed during lockdown and the pandemic. Females (mean = 3.03) were more stressed than males (mean = 2.61) as they were constantly under pressure because of stressful life events (OR = 0.752, 95% CI = 2.425-310.642) and apprehensive about their studies (RII = 0.67, OR = 2.168, 95% CI = 0.332-6.691)., Conclusion: During the pandemic, students' mental health needs to be continually monitored as they are stressed owing to fear as well as about their studies and future careers., (© 2021 The Authors.)

Reproductive performance of crossbred cows reared under traditional low input production system was assessed. A total number of 160 farmers were surveyed and traditional fodders were evaluated for proximate composition. Total protein, albumin and cholesterol concentrations in blood serum were analyzed. The age at first service, age at first calving, calving interval, calving to first service and calving to conception interval were calculated from records of 261 crossbred dairy cows. The crude protein, crude fiber, nitrogen free extract, ether extract and total ash content varied from 7.2 to 13.9, 18.2 to 34.4, 39.1 to 59.2, 2.1 to 4.1 and 7.2 to 17.9%, respectively. The total protein and albumin concentrations in blood serum were 7.6 +/- 0.3 and 4.3 +/- 0.3 g/dl, respectively. The cholesterol concentration was 221.1 +/- 8.2mg/dl. The mean age at first service and age at first calving was 28.6 +/- 1.0 and 40.7 +/- 1.1months, respectively. The mean values for calving to first service and calving to conception intervals were 182 +/- 14.5 and 224 +/- 9.0days, respectively. The conception rate was significantly high among the cows that showed typical fern pattern of cervical mucus (56.6%). The conception rate based on 1(st) insemination was 44.4%. The incidence of repeat breeders and anestrus among the crossbred cows were 12.8 and 14.1%, respectively.

This study was designed to analyze the low input backyard poultry production system practiced by the tribal farmers, and evaluate the performance of an improved dual-purpose breed, the Vanaraja. Results revealed that a significantly (p < 0.05) higher number of farmers used temporary, non-conventional poultry houses made of locally available materials, such as bamboo and wood. Most of the farmers (65.9 %) did not provide balanced feed to their poultry and did not vaccinate their birds against any disease. Under standard management conditions, the average body weight of Vanaraja birds at 6 weeks was 625 +/- 10.9 g. Under backyard conditions, the body weight at 18 months was 3.6 +/- 0.8 kg. The age at first egg was 154 +/- 9 days in the backyard system, whereas under the intensive system it was 196 +/- 4 days. Annual production under the backyard and intensive systems of rearing was 176 +/- 9 and 152 +/- 7 eggs, respectively. Mortality of adult birds was 12 % and predation by foxes and wild cats accounted for 1.67 %. This study revealed that village chickens are an important income source for household expenses, and that traditional free-range poultry production in the smallholder sector of developing countries can possibly be improved through the use of improved dual-purpose birds.
