In order to investigating the effect of exogenous enzymes on growth performance, blood and rumen parametes,18 Brown Swiss male bulls were used in an balanced completely randomized design. The experimental diets were: 1) basal diet (control), 2) basal diet containing 0.50 g enzymatic mixture /kg DM of diet and 3) basal diet containing 0.75g enzymatic mixture /kg DM of diet. The bulls were fed to...
Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...
To compare the relative value of the fish meal and the cottonseed meal in highly fermentable diets (40% forage and 60% concentrate with), eight cows were assigned randomly to diets with 0, 1.5, 3 and 4.5 percent of the fish meal. In the first experiment, the degradability of dry matter and crude protein of the fish meal, the cottonseed meal and concentrate in diets was estimated with different ...
in order to study the effect of sowing date and plant density on some quantitative traits and yield of sugar beet genotypes a field experiment was carried out at sugar beet seed production research station of karaj in 2006. treatments arranged in a split, split plot experiment based on completely randomized block design with four replications. the main factors were two sowing dates as 14 april ...
A mechanistic and dynamic model was developed to represent the physiological aspects of liquid dynamics in the rumen and to quantitatively predict liquid flow out of the reticulorumen (RR). The model is composed of 2 inflows (water consumption and salivary secretion), one outflow (liquid flow through the reticulo-omasal orifice (ROO), and one in-and-out flow (liquid flux through the rumen wall)...
This experiment was conducted to determine the effect of variety and planting year on the nutritive values of corn fed to growing pigs. Four corn varieties examined in this experiment were planted in the same village located in Longhua County, Heibei Province, China, in 2012, 2013, and 2014, respectively. During each year, corn was hand-harvested in early October and sun dried to about 14% mois...
The effect of soil salinity on plant growth is due to two factors, namely, increase in osmotic pressure of soil solution and the ionic composition of salt. The present experiment was conducted to obtain information about the response of pistachio (Pistacia vera L.) to salinity and ionic composition of the salt. Salinity with different relative composition of sodium chloride and sodium sulfate w...
In order to detect the reaction of different potato genotypes to different irrigation regimes and evaluate their water productivity, a research was carried out as a split plot experiment based on a randomized complete block design with three replications in Agricultural Research Center and Natural Resources of Ardabil, Iran in 2015-2016. Five potato genotypes (Agria, Caesar, Savalan, 397081-1 a...
Light availability has a profound effect on plant growth and development. One of the ways to study the effects of light intensity on plant growth and development without the confounding problem of photosynthate availability is sucrose injection/supplementation. A greenhouse experiment was conducted to evaluate the effects of light levels (0% and 75% shade) and sucrose injection (distilled water...
Low light responses of eight garden pea genotypes were investigated in the present experiment in terms of dry matter accumulation and partitioning in the plant. The light treatments consisted of (i) 100% photosynthetically active radiation (PAR) measured in the open field and (ii) 25%, (iii) 50%, (iv) 75% reduction of natural PAR obtained by using mosquito nets of variable color and mesh number...
