The article presents the results of studying pellets crumbliness index a pilot batch extruded compound feed for pike-perch. regimes fish production with minimal crumbling were defined using mathematical model. A 3-factorial central composite design was implemented to obtain model process extrudate resulting in second-degree polynomial. influencing factors include mixture moisture W (%), extrusi...

Feed additives are nonnutritive feed ingredients that are not required by swine. In the absence of feed additives in the diet, no deficiency symptoms will result. They may, however, enhance production and profitability under the right circumstances. Feed additives are regulated in the U. S. by the Food and Drug Administration (FDA), and it is very important that the regulations be followed. The...

The study was designed experimentally using a Completely Randomized Design, five treatments were repeated three times included the use of carboxymethyl cellulose as control much 5%, and treatment feed additives seaweed 75%, 10% 12.5%. parameters measured efficiency, rupture speed test, sink durability stability test moisture content Analysis Variance continued with Duncan's Multiple Distance Te...

Feed technology has advanced in the past two decades. However, NRC (1994) vitamin requirements for the non-ruminant species have not changed to any great extent due to limited research in this area. Conditioning temperatures have increased to reduce microbial contamination and improve pellet quality and/or production rate. From a practical standpoint, vitamin activity may be decreased in finish...

Eighty Holstein-Friesian cows were randomly assigned to four treatment groups of 20. The four groups of twenty cows were fed on diets that were designed to place cows at some degree of risk of ruminal and metabolic acidosis. The cows were fed either 10 kg of pellet and ate pasture, or a subgroup of six cows per group was fed 10 kg of pellet with ad lib forage in a Calan gate facility. Cows in G...

Small-scale fish farmers have financial limitations to buy expensive commercial pellets meet feed needs. Therefore, it is necessary find alternative feeds that are cheap and able support growth. Durian seeds (Durio Zibethinus) Kelakai leaves (Stenochlaena palustris) potential plant materials for additional which abundant in Central Kalimantan Province. This study aims determine whether formulat...

This study evaluated the effect of feeding silage to pigs on nitrogen (N) utilization and ammonia (NH3) volatilization. In total, 128 Yorkshire × Hampshire (30–110 kg) were fed commercial feed (Control) or mixed with dried, milled in pelleted form (Pellet-S), fresh, chopped (Silage-Ch) intensively treated (Silage-Pr). Silage replaced 20% crude protein (g/kg). Diet affected daily N excretion, wh...

Background: Much attention has been paid to poultry feed processing and the contamination In Iran in order to improve the production and reduce the waste.  No information is available on the fungal contamination and the strains found in processed (pellet) and non-processed (mash) poultry feeds. This study was designed to determine the hygienic condition and the risk of fungal contamination...

Four experiments were conducted to investigate the effects of deoxynivalenol (DON) from naturally contaminated dried distillers grains with solubles (DDGS) and the efficacy of feed additives in nursery pig diets. In Exp. 1, 180 pigs (10.3 ± 0.2 kg BW) were fed 1 of 5 diets for 21 d. Diets were 1) Positive Control (PC; < 0.5 mg/kg DON), 2) Negative Control (NC; 4 mg/kg DON), 3) NC + 0.10% Biofix...
