The hypothesis was proposed that the improved embryonic livability observed when higher incubation temperatures were imposed on eggs stored for 15 d prior to setting might have basis in energy metabolism. To test the hypothesis, fertilized turkey eggs were incubated either for the first 2 wk of development (experiment 1) or only the first week of development (experiment 2) at 37.8 degrees C com...

Body weight, livability, and feed conversion of a randombred control turkey line (RBC2) started in 1966 at The Ohio State University was compared with that of modern commercial turkeys hatched in 2003 when fed representative 1966- and 2003-type diets from hatch (March 5, 2003) through 196 d of age. Each pen of modern turkeys consisted of 5 birds each of the Nicholas, British United Turkeys of A...

Step-Up Protein (SUP) rearing regimens can reduce Feed Consumption (FC) and Body Weight (BW), while still resulting in pullets with equal or superior egg production and egg mass to pullets grown on a Step-Down Protein (SDP) program. Egg weight has been reduced due to SUP programs, presumably due to the reduced BW at sexual maturity. Because BW is reduced by SUP regimens and a slight lowering of...

In urban planning, sustainability is often synonymous to livability. Urban livability seeks improve living conditions of current and future outdoor users hence it has become a key priority for cities authorities. Melbourne, as the world second most livable city, sets out its life quality through various policies initiatives. One area improvement creation sustainable spaces that provides comfort...

black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...
