This chapter proposes a novel design methodology for a Multi-stAge noise SHaping (MASH) digital delta–sigma modulator (DDSM) which employs multi-moduli. The structure is termed the MM-MASH. The adequacy and benefit of using such a structure is demonstrated. In particular, the sequence length is lengthened if the quantizer modulus of the first-order error feedback modulator (EFM1) of each stage ...

Acids (110%) as research indicates VZ has protease activity and is optimized at lower CP levels. Diets were fed in the mash form from 0-26 d, and VZ was either added post mixing of original feed (D) or sprayed on top of the feed (L). A total of 168 Ross x Ross male broiler chicks were allocated to 24 pens of a battery brooder in a Completely Randomized Design with 12 replicate pens/control and ...

Primary data were generated from field surveys conducted with the aid of questionnaires, personal interviews, field measurements and conversation between May and August, 2005 on the feeding management practices of 90 smaller holder turkey farmers in Imo State. All of the farmers fed their turkeys with commercial chicken feeds. Fifty (50.00%) of the farmers used chicken layer rations for their b...

The vertebrate central nervous system contains a great diversity of neurons and glial cells, which are generated in the embryonic neural tube at specific times and positions. Several classes of transcription factors have been shown to control various steps in the differentiation of progenitor cells in the neural tube and to determine the identity of the cells produced. Recent evidence indicates...

Male broilers (n = 416) were used to compare the efficacy of providing dietary phytase either as a commercial supplement or as a recombinant protein in transformed soybean. From 7 to 21 d of age, broilers were fed a basal diet containing 0.20% nonphytate P (nP) with additional supplementation by fungal phytase as Natuphos or as raw transformed soybeans expressing recombinant phytase at 400, 800...

Wheat distillers dried grains with solubles (WDDGS) is a by-product that can be an alternative feed ingredient for poultry. However, WDDGS contains non-starch polysaccharides which limit its dietary inclusion. The objective of the current trial was to evaluate the effect of WDDGS with or without Endofeed W on egg quality and performance of laying hens. Endofeed W is a commercial enzyme includin...

The aim of the experiment was to explore the possibility of using free choice feeding technique under diff erent cage density for unselected native chicken. Eighty hens of laying Wareng chicken were divided into two feeding systems. Half of them were fed complete commercial diet of 17% crude protein, with 2800 kcal ME/kg and the other half were subjected to free choice diet. The diets were in m...
