the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...

in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

studying the autecology of range plants provides the basic information on their ecological requirements, cultivation methods and the interactions with the prevailing environment. such information is necessary for a proper range management. some ecological characteristics of astragalus arpilobus kar. & kir., were studied in the winter rangelands of northern khorasan province. it was naturally gr...

efficient use of agricultural wastes due to their recycling and possible production of cost effective materials, have economic and ecological advantages. a biological method used for degrading agricultural wastes is a new method for improving the digestibility of these materials and favoring the ease of degradation by other microorganisms. this research was carried out to study the possible bio...

The experiment was conducted to evaluate losses and nutritive value of elephant grass silage containing increasing levels of cottonseed meal. The experimental design was completely randomized, with five treatments: 0, 7, 14, 21 and 28% inclusion of cottonseed meal, and four replications. The material was chopped and packed in PVC silos and stored for 80 days. The pH and dry matter (DM), crude p...

Ten lactating multiparous Holstein cows were used in a cross-over design with two dietary treatments and 28-d periods (with 14 d as an adaptation) to study the effect of restaurant fat on milk production and composition. Each cow was offered 14.7 kg DM /d of the basal concentrate diet based on barley and corn (crude protein = 17.7%, neutral detergent fiber = 23.5%, and acid detergent fiber = 5....

A comparison between heavily browsed and non-browsed Juniperus pinchotii trees revealed that, in contrast to the recent J. ashei study (Adams et al., 2013), the percentage of total volatile leaf oil yields were not significantly different (P > 0.05) between non-browsed trees (1.08%, DM-basis) and browsed trees (0.94%, DM basis). Only one terpene in the mg/g data, α-pinene, was significantly dif...

Hedychium gardnerianum (HG) and Pittospporum undulatum (PU) are invasive plants all over the world, being in the Azores supplied to cattle on periods of shortage food. As these plants produce secondary metabolites, including a diverse range of phytochemicals compounds, the aim of the present study is to identify how these metabolites can be related to animal’s reproductive performances. For suc...

This study investigated the chemical composition and ruminal degradability of corn stover in three maize-planting regions in Qiqihaer, Heilongjiang Province, China. The whole stover was separated into seven morphological fractions, i.e., leaf blade, leaf sheath, stem rind, stem pith, stem node, ear husk, and corn tassel. The assessment of nutritive value of corn stover and its fractions was per...
