background & aim: drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. in this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. experimental: this study was done in an experimental greenhouse, i.a.u., shahrekord branch, iran at...

Reduction in herbage production and plant diversity on rangelands on the coastal part of croatia, due to invasion of terpene-rich shrubs has been recorded during the recent period. therefore, there is a strong need to understand ecological relationships between plant and animal components of these shrubby ecosystems. through four consecutive experiments, we investigated the potential of two wel...

Organic manures are more preferred and environmentally friendly than chemical fertilizers for minimally contaminating soil, water environmental resources, but the determination of right source organic continues to remain an unexplored aspect. Considering important issue, a multi-year field trial was carried out determine response forage soybean four sources nutrients such as (IF), poultry litte...

Assessments were made of the influence of several microclimatic variables on the availability of third-stage larvae of Ostertagia ostertagi, on pasture herbage. Variables most closely related to recovery of larvae from the lower herbage samples were: maximum air, mat and dung temperatures. Recovery of larvae from the upper portion of the herbage was closely correlated with dung temperature, sam...

Birdsfoot trefoil (Lotus corniculatus) increases milk yield of dairy cows. An indoor feeding experiment using Friesian dairy cows in mid lactation was conducted to determine what proportions of the milk yield and composition changes were due to the condensed tannins (CT) in Lotus, and what proportions were due to factors associated with legumes (higher herbage intake and forage quality). Cows w...

The aim of this study was to compare the n-alkanes and the ytterbium (Yb)/faecal index techniques as two methods for estimating the herbage intake of dairy cows fed indoors on different herbage : supplement ratios and feeding levels. The supplement was a mixture of maize silage and soyabean meal (ratio of 87 : 13 on a dry matter (DM) basis). In all, four treatments were studied. The herbage : s...
