This study was carried out to establish clipping interval of Pennisetum orientale (PO) and Panicum antidotale (PA) to get maximum biomass production with optimal nutritional value for Nili buffaloes. Two clipping intervals i.e. CI1, and CI2 (clipped after every one and two months, respectively) were studied for both grasses. The data on various parameters were compared with PO and PA each clipp...

BACKGROUND On the one hand, the critical nitrogen (N) content curve allows the minimal N content necessary for maximum growth rate at any stage of crop development to be predicted. On the other hand, arbuscular mycorrhizal fungi (AMF) transfer N from the soil to the plants and its growth and activity depends on the availability of soil N. Our objective was to investigate how the availability of...

Tea processing includes several stages and in three of them namely drying, fiber-mat and screening some of the product is wasted. In this study, 25 percent of the tea processing plants in Iran were selected. Three samples were taken from each plant and analyzed for chemical composition and in vitro and in vivo digestibility and voluntary feed intake. Results showed that crude ...

Forages comprise 35% to 70% of the dry matter (DM) in diets for lactating dairy cows. Variation in forage quality can impact DM intake, diet energy density, dietary grain and protein supplementation amounts, feed costs, lactation performance, and cow health. Forage quality is highly variable among and within forage types (NRC, 2001). Forage species, variety or hybrid, stage of maturity at harve...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

Rumen fill and turnover rates of liquid, grain, and hay in the gastrointestinal tract were measured using rare-earth elements as multiple markers in four rumen fistulated cows during the dry period and throughout lactation. Apparent digestibilities of dry matter, crude protein, neutral-detergent fiber and aciddetergent fiber were also measured. Hay to grain ratios of 82.5:17.5, 45:55, 57:43, an...

The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral Detergent Fiber (NDF), a...

Seeds of 200 accessions of alfalfa (Medicago sativa L.) were provided from Iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of Hamadan, Iran during 2009 to 2010. The data were collected and analyzedfor plant height, stem number, leaf stem ra...

Twenty growing Small East African goats were used to determine the effects of feeding sun-dried leaves of the browse forages Berchemia discolor and Zizyphus mucronata as supplements to low-quality basal diet, Rhodes grass (Chloris gayana) hay, on voluntary feed intake (VFI), digestibility and growth performance. The grass hay and maize bran were used as a control. The dried leaves were then inc...
