“…The most common solution for breeding heat adapted cattle to date has been through crossbreeding Bos taurus and Bos indicus cattle 75 . While this has led to cattle better equipped to handle hot and humid environments, it has come at the cost of decreased meat quality 76,77 . Further, Bos indicus crossbreeding is unable to improve adaptation to a wide variety of other environmental stressors such as cold temperatures, high elevations, and a host of other biotic and abiotic factors.…”

Selection is a basic principle of evolution. Many approaches and studies have identified DNA mutations rapidly selected to high frequencies, which leave pronounced signatures on the surrounding sequence (selective sweeps). However, for many important complex, quantitative traits, selection does not leave these intense signatures. Instead, hundreds or thousands of loci experience small changes in allele frequencies, a process called polygenic selection. We know that directional selection and local adaptation are actively changing genomes; however we have been unable to identify the genomic loci responding to this polygenic, complex selection. Here we show that the use of novel dependent variables in linear mixed models (which allow us to account for population structure, relatedness, inbreeding) identify complex, polygenic selection and local adaptation. Thousands of loci are responding to artificial directional selection and hundreds of loci have evidence of local adaptation. While advanced reproduction and genomic technologies are increasing the rate of directional selection, local adaptation is being lost. In a changing climate, the loss of local adaptation may be especially problematic. These selection mapping approaches can be used in evolutionary, model, and agriculture contexts.

“…Accordingly, higher levels of concentrate feed in the finishing period of the animals confined result in a higher concentration of oleic acid and MUFA in the intramuscular fat [31]. Although the adipogenic mechanism is extremely complex, several genes were identified and confirmed as being responsible for fatty acid composition in beef [20,[32][33][34][35][36][37][38][39][40][41].…”

The consumer's profile has changed, and in recent years, there has been a greater concern for the nutritional quality of meat, especially in relation to fat that compose it. The meat fat composition can contribute to the onset of cardiovascular disease. On the other hand, fat is an essential component in the human diet, as well as providing energy; it contains essential fatty acids (FAs) that must be present in food. The meat nutritional properties are largely related to its fat content and fatty acid composition. In addition, fat gives flavor to food, helps in the absorption of vitamins, and plays an important role in the immune response, for humans, and animals. The fat nutritional and sensory quality in meat that is determined by the fatty acid composition can affect the degree of fat saturation, the storage stability, and flavor. There are several factors that can influence the fatty acid composition, such as animals' species, breed, sex, and diet, causing various changes in carcass, as well as in tissues and chemical meat composition.

proteomics is able to reveal plentiful information related to different physiological and pathological states of biology. Further, the determination of accurately proteomic pattern is the essential platform for deeply proteomic research. While this has been somewhat ignored so far. In this article the quantitative standard Pg=61%, a biological similarity constant for discriminating accurately intrinsic proteomic patterns was established depending on biological common heredity and variation information equation in symmetric variation state. On the other hand, a novel theoretical method was proposed for linearly dividing nonlinear data sequence into linear segments. The proteomes of three kind soybeans were precisely distinguished from one another by analyzing their infrared fingerprint spectra relying on this theoretically systemic approach. Additionally, methods employed in this paper enable us to quickly, accurately and quantitatively determine the proteomic patterns without using any prior knowledge and learning samples, and without using electrophoresis, high performance liquid chromatography-mass spectrometry techniques, which are high cost, time-consuming. This approach provide us with an excellent one for quickly accurate determining biological species, physiological states and diagnosing pathological states based on proteomes.
