As of 2012 in Australia and using dressed weight for the output, a FCR calculated using weight of dressed meat of 4.5 was fair, 4.0 was considered "good", and 3.8, "very good". [17] The FCR of pigs is greatest up to the period, when pigs weigh 220 pounds. During this period, their FCR is 3.5. [16]
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meat production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [ 7 ] to address the dynamics of the combined grass-animals system as a predator-prey ...
The gestation period for a cow is about nine months ... About a quarter of the world's meat comes from cattle. [100] World cattle meat production in 2021 was 72.3 ...
For 2002–2003, the United Nations' Food and Agriculture Organization (FAO) estimates of industrial production as a percentage of global production were 7 percent for beef and veal, 0.8 percent for sheep and goat meat, 42 percent for pork, and 67 percent for poultry meat.
As the cow's gestation period is a little over 9 months this means the cow must be inseminated by the age of 15 months. Because the breeding process is inefficient, most producers aim to first breed their heifers between 12 and 14 months.
A cow calf operation is a method of rearing beef cattle in which a permanent herd of cows is kept by a farmer or rancher to produce calves for later sale. Cow–calf operations are one of the key aspects of the beef industry in the United States and many other countries. [1] In the British Isles, a cow–calf operation may be known as a single ...
This approach is based on regression models developed for determining efficiency of feed use for weight gain during a standardized growth trial in growing beef cattle. [ 3 ] It was inspired by Koch's observations of the differences in how a maintained body weight and an increasing body weight affect the feeding of cattle.
