In order to investigate the effects of sowing date on yield and some agronomic traits of six forage maize hybrids, two experiments were conducted in 2009 in two locations including Rasht and Fuman. The experimental design was randomized complete blocks with factorial arrangement and three replications. Treatments consisted of three levels of sowing date (31 May, 13 and 26 June) and six maize hy...
In order to map the genomic regions affecting barley forage quantity and quality, two experiments were conducted with 72 doubled haploid lines and their two parents (‘Steptoe’ and ‘Morex’), at the Research Farms of the Faculty of Crop and Animal Sciences, University College of Agriculture and Natural Resources, University of Tehran and Agriculture and Natural Resources Research Station of Sista...

The Swedish dairy cow has almost doubled its annual milk yield over a few decades. This has simultaneously led to an increase in the dietary proportion of concentrate in order to meet the increased nutritional requirement of dairy cows. The proportion of forage is often below 50% of dry matter (DM) intake in conventional dairy production on an annual basis. However, the regulations for organic ...
Previously, a linear relationship has been found between net energy intake (NEI) and dietary chewing index (CI) of the diet for different types of cattle. Therefore, we propose to generalize and calibrate this relationship into a new model for direct prediction of NEI by dairy cows from CI values (CINE; min/MJ of NE). Furthermore, we studied the forage-to-concentrate substitution rate in this n...
Weaned Targhee x Hampshire lambs (average BW 27.6 kg) were used to determine the effects of concentrate feeding, forage grazing, or finishing on concentrate after grazing upon growth and carcass tissue accretion. Lambs were assigned randomly and balanced by weight and sex to five replicated treatments (12 lambs/treatment): all-concentrate in drylot (DL); rotational grazing alfalfa (ALF); rotati...
. an experiment was conducted by incorporating 35 newborn balouchi lambs to study the effects of different type and levels of forage in starter diets on rumen development characteristics and performance. the 5 experimental treatments were included; starter diet without forage (control) and starter diet containing two levels (7.5 and 15%) of alfalfa hay and wheat straw. inclusion of forages incr...
