Bay scallop (Argopecten irradians) is one of the most economically important aquaculture species in China. In this study, we constructed a consensus microsatellite-based genetic linkage map with a mapping panel containing two hybrid backcross-like families involving two subspecies of bay scallop, A. i. irradians and A. i. concentricus. One hundred sixty-one microsatellite and one phenotypic (sh...

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...

Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars between the K (2.0 − 2.4 μm) and L (3.4 − 4.1 μm) bands. Aiming at an explanation of these findings, we chose the objects α Orionis (Betelgeuse), SW Virginis, and R Leonis, which are of different spectral types and stages of evolution, and which are...

Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...

Cardiac output (CO) and regional blood flow to various tissue were measured by means of gamma-labeled plastic microspheres (15 +/- 3 micrometers) injected into the left ventricle during 30-min infusion of l-norepinephrine (NE:4 micrograms(kg.min)) or the same amount of saline (11 microliters/min per animal) in rats physically trained by 2-hr swimming in water of 32 (SW-32), 36 (SW-36), and 38 d...

A series of simulations were performed to evaluate the effects of mature size (WMA; 60, 70, 80 and 90 kg), slaughter weight (SW; 55, 60 and 65 kg) and three diets fed to feedlot lambs. Rations included a traditional diet (C2L) or placing weaned lambs on alfalfa for either 30 (A30) or 60 (A60) d before placing them on the C2L diet (A30-C2L and A60-C2L). Two lamb pricing schemes were used in the ...

Table eggs collected at random from one-hundred and fifty layers (75-FUNAAB-Alpha 75- ISA brown) kept Breeding Unit, Teaching Research Farm, Olusegun Agagu University of Science Technology, Okitipupa 31st, 33rd, 35th weeks (WK) age were analyzed for internal external characteristics within 24 hours laying. The data subjected to analysis variance assess the effect breed on egg quality. Breed had...
