Estrous synchronisation is the process of targeting female mammals to come to heat within a short time frame (36 to 96 hours). This is achieved through the use of one or more hormones. Methods to improve our ability to synchronize the reproductive process and result in the ‘timed insemination’ without the detection of heat have been developed.
A 2022 study in the Lancet Planetary Health found that cattle heat stress losses will be far greater in most tropical regions than in temperate regions, ...
Project cycle management (PCM) is the process of planning, organizing, coordinating, and controlling a project effectively and efficiently throughout its phases, from planning through execution then completion and review to achieve pre-defined objectives or satisfying the project stakeholder by producing the right deliverable at the right time, cost and quality.
The essential principles of OFDR technology are the quasi continuous wave mode employed by the laser and the narrow-band detection of the optical backscatter signal. This is offset by the technically difficult measurement of the Raman scattered light and rather complex signal processing, due to the FFT calculation with higher linearity ...
Cattle are not often kept solely for hides, and they are usually a by-product of beef production. Hides are used mainly for leather products such as shoes. In 2012, India was the world's largest producer of cattle hides. [114] Cattle hides account for around 65% of the world's leather production. [115] [116]
Hundreds of cattle died in Iowa from extreme heat and humidity in late July, the state and livestock producers said, as the world recorded its hottest month ever. The losses further trim the U.S ...
Dairy cattle are polyestrous, meaning they cycle continuously throughout the year. They tend to be on a 21 day estrus cycle. However for management purposes, some operations use synthetic hormones to synchronize their cows or heifers to have them breed and calve at the ideal times. These hormones are short term and only used when necessary.
Environmental conditions such as ventilation and temperature should be considered. Managing heat stress can be implemented through the use of shade and water sprinklers. Research has shown that heat stress during this period can compromise the immune system, reduce mammary tissue development and reduce milk production following lactation. [10]
