The effects of Lactobacillus plantarum and Propionibacterium acidipropionici on corn silage fermentation, ruminal degradability and nutrient digestibility in sheep
The chemical composition, in situ ruminal degradability coefficients of dry matter (DM), and nutrient digestibility in sheep were evaluated for corn silage (CS) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (I) as follows: (1) untreated CS (control); (2) CS + I at half of the recommended level; (3) CS + I at the recommended level (3 1010 colony forming...
متن کاملStudy on Combining Ability and Gene Effects Estimation in Some Sweet Corn Inbred Lines (Zea mays L. var saccarata) by Line × Tester Method
In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...
متن کاملStudy on gene action and combining abilities for thermotolerant ablilities of corn (Zea mays L.)
High temperature reduces the pollen viability and silk receptivity of corn resulting in poor seed set and reduced yield. Continuously increasing temperature and less frequency and distribution of rainfall coupled with usual canal–closure particularly in Pakistan have significantly been decreasing the grain yield. This problem could be overcome by developing heat tolerant maize hybrids. For this...
متن کاملThe effects of a microbial inoculant and formic acid as silage additives on chemical composition, ruminal degradability and nutrient digestibility of corn silage in sheep
The effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (DM) and nutrient digestibility of corn silage wereexamined. Whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: Propionibacterium acidipropionici plus L...

Young leaves of two corn (Zea mays) inbreds with normal and Texas male-sterile cytoplasm, which differed in their susceptibility to Helminthosporium maydis Nisikado and Miyake race T, showed no significant qualitative or quantitative differences in their isoperoxidase patterns. Of six cathodic and four anodic isoenzymes present in the soluble fraction, four and two, respectively, comprised the ...
