The article presents the results of feeding broiler chickens with different doses feed additive "M-feed". It was found out that use optimal dosage "M-feed" in chickens' diets contributed to an increase absolute gain by 7.7%, average daily 7.6%, and gutted carcass weight 12.9%, contrast control group.

Feed efficiency has a major influence on the unit cost of beef cattle production. Gibb and McAllister (1999) have reported that a 5% improvement in feed efficiency has an economic impact four times greater than a 5% improvement in average daily gain. In addition, the cost of feed is second only to fixed costs in importance to the profitability of commercial beef operations (Basarab, 1999). The ...

This study investigated aflatoxin B1 (AFB1) contamination in dairy cow feed and the risk management of AFB1 content in concentrates undertaken by feed industries in the Parmigiano Reggiano area. Data on aflatoxin contamination risk management applied in 29 feed industries were collected and the AFB1 content of 70 feed samples was analysed. Data were collected within the framework of a quality c...

There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...

In this experiment, the effect of prebiotic Bio-Mos® (MOS) and types of feed formulation (total and digestible amino acids) were evaluated on performance and the small intestine microflora in laying hens for a duration of 10 wks. A total of 168 Hy line W-36 laying hens, with an initial age of 73 wks, were randomly allocated to 4 dietary treatments, 7 replicates and 6 birds in each replicate. Th...

Genetic relationships of measures of residual feed intake and daily feed intake with serum IGF-I concentrations at 8 wk of age and at 105 kg of BW, serum leptin concentration at 105 kg of BW, meat quality, and different fat accumulation traits on 834 Duroc pigs in 7 generations were estimated. Two measures of residual feed intake were estimated from the differences between actual and predicted ...

A variety of measures including Relative Feed Value (RFV), Relative Feed Quality (RFQ) and Total Digestible Nutrients (TDN) have been used to set the value of alfalfa hay for sale. However, components or characteristics of alfalfa in addition to these measures may prove useful in determining the real market and feeding value of alfalfa compared to other feeds.
