Densified complete feed (DCF) is a formulated feed that produces through the blending of feedstuffs in the desired proportion to provide balanced nutrition for animals. The DCF gives a good impact on animal performance and reduce the feed cost for farmers. However, there is lacking of DCF production for goat consumption. Therefore, the aim of this study was to investigate the effects of different levels of molasses as binder on hardness, durability and chemical composition of DCF. In preparation of DCF, the locally available feed ingredients such as oil palm frond were collected and the making process of complete feed blocks was referred. The DCF was made manually including 3% and 6% molasses level, and then prepared to fulfil the nutrient requirement of growing goats as recommended by National Research Council. The durability was carried out on days 0, 7, 14 and 28 by comparing the hardness, dry matter (DM), and colony forming unit (CFU) of each molasses rate of DCF. Both molasses of DCF had shown a decreasing trend on durability from days 0 to 28. Regardless of durability, the DCF with 3% molasses had greater hardness (2.1 kg/cm2), higher DM content (93.2%) and lower CFU count (1.3 ×104 CFU ml−1) than that of 6% molasses rate of DCF. Both different rates of molasses of DCF had no significant (p>0.05) effect on crude protein, crude fibre, ether extract and ash contents. The present study suggests that 3% molasses of DCF is preferable in terms of longer storage, while 6% molasses of DCF may be more palatable for the ruminants.
Coin, as a very important part of the financial system, has been paid great attention and widely used in our daily life. This paper introduces a kind of creative coin sorting mechanism design based on Archimedes double helix, adopting photoelectric sensor to count classification. It abandoned the traditional vibrating or partial time selection model, and finally realizes the efficient sorting inventory of a large number of coins. Its feature is that it can realize continuous type of sorting classification and counting with a larger amount per unit of time. The product mainly adopts mechanical structure and additional simpler circuit control for a low manufacturing cost.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
