a three-year field experiment was conducted under conditions of luvic chernozem soil. diversified nitrogen fertilization with 0, 60, 120, and 180 kg n ha-1, and microbial preparations improving soil properties were applied to potatoes, cv. ‘satina’, cultivation. n–no3 concentration in the soil profile (0–0.9 m) in autumn after potato harvesting fluctuated from 28 kg n ha-1 in the n0 treatment t...

Inter-sexual segregation between habitats or between sites within a habitat is very widespread in sexually dimorphic ungulates. As an explanation, it has been suggested that males, because of their larger forage requirements, are driven from preferred, high quality forage habitats into marginal habitats of lower forage quality but higher forage biomass by female competition (`indirect competiti...

High acidity and low soil P availability in the soils from Pampa natural grasslands generally limit forage growth economic return. Thus, to increase return avoid environmental degradation biodiversity loss due replacement by intensive cropping systems, it is essential improve availability. This study aimed diagnose nutritional status of pluri-specific amended with different history sources. Add...

to study the effect of planting rates and harvest time on forage quality of maize in maize-cowpea intercropping, an experiment was conducted at the research farm of zabol university, during 2007 and 2008. the experiment was arranged in a 7×2 factorial one in complete randomized block design with 4 replications. the two factors consisted of seven planting ratios of maize and cowpea (100:100, 100...

The aim of this thesis was to increase our understanding about chicory (forage and root) as fibre source for pigs, by studying the effects of diets with inclusion of chicory on digestibility, digestion site, performance, gut microbiota and environment. In total 62 pigs were used, including newly weaned and growing intact pigs and growing post valve t-caecum (PVTC)-cannulated pigs. The weaned pi...

The objective of the current study was to examine whether step-down (STP) milk feeding method together with forage provision would improve performance, rumen fermentation, nutrient digestibility, blood metabolites, and structural growth of calves. Holstein bull calves ( = 40) were randomly assigned to 1 of 4 treatments in a completely randomized design with a 2 × 2 factorial arrangement. Treatm...

The rapid decline in bumblebee populations within Europe has been linked to habitat loss through agricultural intensification, and a consequential reduction in the availability of preferred forage plants. The successful introduction of four European Bombus species to the South Island of New Zealand from England (in 1885 and 1906) provides an opportunity to determine how important different fora...

The objectives of this study were to examine long-term effects of feeding forage rape (Brassica napus L.) on methane yields (g methane per kg of feed dry matter intake), and to propose mechanisms that may be responsible for lower emissions from lambs fed forage rape compared to perennial ryegrass (Lolium perenne L.). The lambs were fed fresh winter forage rape or ryegrass as their sole diet for...

Khorvash, M., Colombatto, D., Beauchemin, K. A., Ghorbani, G. R. and Samei, A. 2006. Use of absorbants and inoculants to enhance the quality of corn silage. Can. J. Anim. Sci. 86: 97–107. This study examined whether inoculants and various absorbent materials could be used during ensiling to reduce effluent losses and improve nutritive value of corn silage. Two corn forages were harvested: conve...
