When the cattle were given feed that does not meet both the quality and quantity standards, there will be a decline in production. Therefore, the ability to select high-quality feed is absolutely owned. Fodder plays a very important role in world farming. Seen in terms of cost, fodder ranked the highest, ie 70% of the total production cost. See the guide to choose the correct feed below.
Therefore, breeders need to pay attention to this food problem, especially in terms of quality. Because, when cattle were given feed in sufficient quantity, quality and quantity, the animal can be optimally productive.
Besides having the ability in choosing and using quality feed, farmers must also consider the problem of storage, because the selection of good food without the support of qualified storage will only be in vain. A. Jonah (1990), convey a guide how to choose a good animal feed.
Terms of good food
Good fodder according to Yunus, is the fodder that is not / has not / very few changes, so does not degrade the nutritional value. Food that is well marked by the absence of defects in the feed, either physical, chemical and biological, among others:
Physical damage
This damage occurs in the form of outer / physical food, which is characterized by the general condition of feed that was different from the feed is still good. It can be identified by macroscopic observation (observation our senses). Feed was also abnormal shape, seen in the presence of holes, his skin peeling or cracked. This disorder can be caused due to a fungus or insect.
Chemical damage
This damage occurs in the chemical composition of feed caused by the presence of certain chemical processes. For example occurred in carbohydrate fermentation, ketengikan in fat, and decay in the protein), resulting in a decline in nutritional value of feed.
Biological damage
Due to the activity of living things in the feed so that in addition to a decline in nutritional value are also not infrequently lead to health problems in livestock that consume them. As an example of an insect on the feed. A large number of insects can cause damage to generate heat, increasing water content, or chemical contamination by feces.
Insect feces containing these contain most of the urea in the uric acid produced by the chemical solution in the digestion during the feeding insect. Another example is the damage by mycotoxins produced by fungus-specific fungus. Poultry is very sensitive to damage caused by mycotoxins.
These mycotoxins are very dangerous and can lead to death. Susceptible poultry deaths from the attacks aflatoxin in feed produced by aspergillus flavus.
To obtain high feed and feed berkualiatas no damage, then there are things that must be considered breeders, among others: First, buy high-quality feed from a trusted source and need to know how storage and treatment of the feed. Second, the drying of feed to be stored with a maximum water content of 14%. Drying can kill the fungus.
Food should be put in airtight containers, water and light. Third, improve the warehousing system. Warehousing is good to protect cattle feed from the possibility of shock-temperature environment, climate, preventing entry of water, insect disturbances and theft.
Warehouse floor surface is made slightly tilted to one direction for water disposal. The temperature inside the warehouse should be 27 C, with a wind that is not too hard. Ventilation allows enough air circulation dry with relative humidity 70%. The condition of the cage a good / ideal to prevent the growth of mycotoxin-producing fungi, because Flavus will grow well only when the relative humidity above 80% with optimum temperature of 32-38 C.
Pemcegahan fungi can also be done by adding the feed aditive, for example with ascorbic acid, propionic, acetic, etc.. The fourth step is the prevention / eradication of insects. This can be done by fumigation and spraying insektidida in the warehouse.
Insects in a pile of bags on the floor can be killed by fumigation, using phosphine or methyl bromide. Spraying insecticide on the walls, floor and roof are still going to be more effective if the surface cool, clean, not too bad and free from cracks
