αCypermethrin-Induced Biochemical and Molecular Cascades Underlying Ovine Ovarian Granulosa Cell Dysfunctions.

The present study was conducted to evaluate the impact of α-Cypermethrin (αCYP), the second most commonly used pesticide in India, on the ovine ovarian granulosa cells (GCs) viability, growth, apoptosis, and steroidogenesis. GCs collected from abattoir-derived ovine ovaries were cultured for 3/6 days in the presence of various concentrations of αCYP (0, 1, 10, 25, 50, and 100 μM). The results revealed a binary effect on GCs, where metabolic activity and viability rates were significantly (p < 0.

Climate Resilience in Farm Animals: Transcriptomics-Based Alterations in Differentially Expressed Genes and Stress Pathways.

The livestock sector, essential for maintaining food supply and security, encounters numerous obstacles as a result of climate change. Rising global populations exacerbate competition for natural resources, affecting feed quality and availability, heightening livestock disease risks, increasing heat stress, and contributing to biodiversity loss. Although various management and dietary interventions exist to alleviate these impacts, they often offer only short-lived solutions.

Further, the effect of nano purification on other sperm functional attributes was also assessed.

A combination of calcium hydroxide and sodium hydrosulphate controls pathogens causing environmental mastitis in recycled manure solids.

Recycled manure solids (RMS) are dried cow dung processed using a manure dewatering machine and subsequently sun-dried to ~ 20% moisture. Benefits of RMS include abundant availability, low cost, and eco-friendliness, but its use as bedding material for cows is hindered by a moisture content that promotes microbial growth. This in vitro study evaluated impacts of calcium hydroxide (CH; 5 and 7.

Oat Brewery Waste Decreased Methane Production and Alters Rumen Fermentation, Microbiota Composition, and CAZymes Profiles.

The transformation of oat brewery waste (OBW) into livestock feed could be a potential replacement for the expensive concentrate and one of the effective approaches for avoiding health hazards due to the accumulation of oat brewery waste in the environment. To explore the potential of OBW as a methane (CH) mitigating agent, an in vitro study was undertaken to investigate the effect of graded replacement of concentrate with OBW on CH production, microbiota, feed fermentation, and CAZymes. A total of five treatments with variable proportions of OBW were formulated.

Effect of biowaste inclusion on methane production, feed fermentation, and microbial diversity.

studies were undertaken aiming to study the methane (CH) mitigation potential of biowaste (BW) of at the graded inclusion of 0% (C), 2% (A), 5% (A), and 10% (A) of the diet composed of straw and concentrate in 40:60 ratio. The chemical composition analysis revealed that the BW contained higher crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and ether extract (EE) than the PF (fresh seaweed, ). The concentration of cinnamic acid, sinapic acid, kaempferol, fisetin p-coumaric acid, ellagic acid, and luteolin in BW was 1.

Genome-wide DNA methylation profiles regulate distinct heat stress response in zebu (Bos indicus) and crossbred (Bos indicus × Bos taurus) cattle.

Epigenetic variations result from long-term adaptation to environmental factors. The Bos indicus (zebu) adapted to tropical conditions, whereas Bos taurus adapted to temperate conditions; hence native zebu cattle and its crossbred (B indicus × B taurus) show differences in responses to heat stress. The present study evaluated genome-wide DNA methylation profiles of these two breeds of cattle that may explain distinct heat stress responses.

Comparative assessment of growth performance, heat resistance and carcass traits in four poultry genotypes reared in hot-humid tropical environment.

This study investigated the impact of heat stress on growth and carcass traits in four poultry genotypes-Giriraja, Country chicken, Naked Neck and Kadaknath reared in a hot and humid tropical environment. Birds from all genotypes had ad libitum access to feed and water while being challenged with consistently high environmental temperatures in the experimental shed. Daily diurnal meteorological data were recorded inside and outside the shed.

Genistein effect in cultured ovine ovarian granulosa cells.

Genistein, an isoflavone has the potential to mimic, augment, or dysregulate the steroid hormone production pathways.

Urbanisation threats to dairy cattle health: Insights from Greater Bengaluru, India.

Complex urbanisation dynamics, on the one hand, create a high demand for animal products, and on the other hand put enormous pressure on arable land with negative consequences for animal feed production. To explore the impact of accelerated urbanisation on dairy cattle health in urban farming systems, 151 farmers from different parts of the Greater Bengaluru metropolitan area in India were individually interviewed on aspects addressing cattle management and cattle health. In addition, 97 samples of forages from the shores of 10 different lakes, and vegetable leftovers used in cattle feeding were collected for nutritional analysis.
