We determined the impact of creep feed provision and type on pre- post-weaning growth performance piglets. At 2 wk post farrow, litters (n = 50) were given no or provided a simple feed, complex both until weaning at ∼28 d. Creep regardless type, resulted in increased (P < 0.05) piglets final week pre-weaning immediate post-weaning, which was not maintained end nursery period. Piglets showed ...

An on-line monitoring and prediction of surface roughness in grinding is introduced with experimental verification. An adaptive neurofuzzy inference system (ANFIS) is used to monitor and identify the surface roughness online. The system uses a piezoelectric accelerometer to generate a signal related to grinding features and surface finish. The power spectral density (PSD) of this signal is used...

Why process at all? Of course, the answer is ultimately feed efficiency, producing the most milk, eggs, meat or fiber at the lowest possible cost. Particle size reduction as the first step in the feed manufacturing process works toward the goal of improved feed efficiency by increasing the surface area of the materials being processed. This increases the amount of materials exposed to the anima...

creep compliance is one of the fundamental tests of mechanistic- empirical flexible pavement design procedure in the aashto 2002 design guide. in this research, a new artificial neural network model for estimating the hma creep compliance with the generalization ability of r=0.949 has been developed successfully using feed forward multi layer perceptron artificial neural networks (anns) with le...

Two experiments were conducted to investigate using alfalfa leaf meal (ALM; 22% CP, DM basis) in beef cattle diets. In Exp. 1, a total of 24 late-gestation Angus heifers (initial BW 470 +/- 9 kg) were blocked by BW, calving date, and BCS to 1 of 4 dietary treatments in a randomized complete block design. All heifers were offered a basal hay diet (7.4% CP and 67.6% NDF, DM basis). Treatments wer...

A judicious choice of insert material, tool geometry and cutting conditions can make hard turning produce better surfaces than grinding. In the present study, an attempt has been made to investigate the effect of cutting tool materials on cutting forces (feed force, thrust force and cutting force) in finish hard turning of AISI D2 cold work tool steel. In conclusion of the results obtained with...
