Analysis of animal feed in livestock business
In livestock business, more than 60-70% expenditure cost is for feed. Therefore, it is necessary to provide feed with a balanced ration arrangement that is feasible and able to produce livestock products economically. In general, the diversity of feeds is very large, therefore the most critical step in the analysis process is the implementation of feed sampling. Accurate feed analysis results start from appropriate sampling techniques in the field Accurate feed analysis begins on-farm with proper feed sampling techniques. The feed is sampled while it is being stored during storage and when the feed is removed. The sampling technique is different for each type of feed, the same is the accuracy in sampling
Sample or sample according to Oxford Dictionary: a number of small independent material or object, which represents and can be used to conclude the quality of mass, group, type and others. Meanwhile,according to the Webster Dictionary, some are representative of the group, which is taken as evidence of the quality or character of the entire group. So the sample is a representative representation of a group or population that is quite large. The feed group can vary depending on the object being evaluated, for example in animal feed: feed ingredients and finished feed. Feed ingredients
Fresh forage or hay are considered one group if they are the same: type, age of cutting, fertility of the land, conditions at harvest and
impossible to analyze a group of feed that storage. Sampling must be done because the number is large. For each penis of the available feed group, one sample that is representative of each group must be prepared. In order to obtain a representative sample, subjective factors must be avoided so as not to be biased The accuracy of the analysis of a feed ingredient being analyzed depends on the sample submitted. Samples collected with good sampling techniques will result in a good analysis of feed ingredients as well. Therefore, the process of sampling feed ingredients must be carried out properly so as to produce a representative sample. For those who take feed samples, namely researchers, laboratory assistants, feed quality control officers, buyers and sellers of feed, they must understand the correct sampling method.
