this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

Protease production by alkalophilic B. licheniformis N-2 was investigated in 50 mL of the growth medium consisting of (in g/L): glucose 10.0, soybean meal 10.0, K2HPO4 3.0, MgSO4·7H2O 0.5, NaCl 0.5 and CaCl2·2H2O 0.5 at pH=10. Different carbon and nitrogen sources in the form of fine powder of organic, inorganic and defatted meals were studied to select the suitable substrate for alkaline prote...

To investigate apparent ileal and faecal digestibility of protein and amino acids in some tropical feedstuffs, six barrows, average initial body weight (BW) 25 kg, were fitted with a simple T-cannula at the distal ileum and fed six diets according to a 6 × 6 Latin square design. Three monodiets which three types of cereal, broken rice, rice bran and corn, as the protein source and three cornsta...

The influence of nematodes on nodulation of soybean varied according to their modes of parasitism. In the greenhouse, nodule formation was stimulated by the endoparasites, Meloidogyne hapla and Pratylenchus penetrans, but was inhibited slightly by the ectoparasite, Belonolaimus longicaudatus. In an experiment under controlled conditions in a phytotron, Heterodera glycines severely inhibited nod...

Influence of elevation and applied nitrogen on rhizosphere colonization and competition for nodule occupancy by different rhizobial strains on field-grown soybean and common bean. Can. J. Microbiol. 36: 92-96. In the absence of indigenous rhizobial populations, the pattern of competition between inoculum strains for nodule o...
