摘要:
The present invention relates to a method for determining the quantity of methane produced by a meat ruminant, such as a bovine, i.e., an animal raised and then slaughtered for the sale of its meat, characterized in that it consists in determining the quantity of at least one fatty acid (FA) contained in a reference tissue, namely muscle or adipose tissue, sampled from said ruminant after its death (in grams of fatty acids per kilogram of tissue) and calculating said quantity of methane (in grams of CH4 per kilogram of meat from the animal) according to an equation that is a function of said quantity of said FA and the category, age and weight of said animal, wherein the latter three criteria are determined at the time of the slaughter of said animal.
摘要:
A method involves at least measuring the weight quantity of at least one fatty acid (AG), derived from de novo synthesis, in a sample of milk from said ruminant and evaluating said quantity of methane according to the following formula: CH4=a*(de novo AG)+y*(BH AG)+z.

摘要:
The present invention relates in particular to a method to evaluate the quantity of methane produced by a dairy ruminant. The method comprises determination of the ratio between the quantity of fatty acids with 16 carbon atoms or less and the sum of the total fatty acids of the milk, said quantity of methane being defined by the following equation: Quantity CH4=(FA
摘要:
The present invention relates to a method for determining, from a database, the amount of at least some fatty acids contained in various biological materials from a single animal raised for meat production. Said method can be used for determining the amount of both major and minor fatty acids, as well as the fatty acid content of another biological material from said single animal.
摘要:
The nutritional quality of milk lipids is determined by a method for predicting percentages of minor fatty acids in milk. A database is created by correlating known fatty acid profiles of reference milk samples obtained by gas phase chromatography to mid-infrared spectra to obtain calibrations, wherein the calibrations vary in accuracy from one fatty acid to another. The determination of a milk fatty acid profile to be analyzed through infrared treatment is limited to some fatty acids with a satisfactory calibration. Equations to predict the percentages of minor fatty acids are developed using correlations of fatty acids with satisfactory calibrations.
摘要:
A method for determining the nutritional quality of milk lipids, involving the steps consisting in considering a defined number of reference milk samples; determining, for each of said reference samples, a fatty acid profile and an infrared spectrum obtained through reflection on the reference sample of a radiation in the mean infrared and associating respectively the fatty acid profiles to the infrared spectra, subjecting the milk to be analyzed, the lipid nutritional quality is to be determined, to an infrared radiation, so as, through reflection, to infer an infrared spectrum, and comparing the milk infrared spectrum to be analyzed to the infrared spectra of the reference samples, so as to infer a fatty acid profile of the milk to be analyzed.
