water productivity is a function of crop yield and management operation. determination of different yield levels through field experiments is difficult. therefore, applying simulation model is an approach which makes possible to assess water balance, simulate growth process and survey different scenarios. using the cropsyst crop growth model to analyze water productivity, as an indicator of wat...

Four experiments were conducted to examine effects of dietary wheat middlings (midds), corn dried distillers grains with solubles (DDGS), and NE formulation on nursery pig performance and caloric efficiency. In Exp. 1, 180 nursery pigs (11.86 ± 0.02 kg BW and 39 d of age) were fed 1 of 5 diets for 21 d, with 6 pigs per pen and 6 replications per treatment. Diets were corn-soybean meal based and...

effects of different levels of dietary nucleotides (nt) were studied on muscle amino acid profile of rain bow trout with an average weight 11.35±0.32 over 8 weeks. this experimental was carried out in 700 l circular tanks with 40 fish per tank. nt was added to the diet at the rates of 0.0, 0.05, 0.1, 0.15 and 0.2%. fish were fed 5 times a day at a rate of 3-5% body weight. after 8 weeks of feed...

Effects of adding fermented wheat to liquid diets on gastrointestinal characteristics in weanling piglets were studied. Gastrointestinal characteristics of 40 28-d-old weanling piglets were measured at the day of weaning (d 0) and at d 4 and 8 after weaning. Piglets were group-housed and fed twice daily. Feeding level was based on the average metabolic BW of piglets per group. Groups were fed a...

Three experiments were conducted to study the property of xylanase and the effects of xylanase in wheat-based diets on growth performance of broilers, respectively. Experiment 1 was performed in vitro to evaluate the effect of different pH and temperature on xylanase activity, and to evaluate the enzymic stability under different conditions. The results indicated that the optimum temperature an...

A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...

Radiant spring frosts occurring during reproductive developmental stages can result in catastrophic yield loss for wheat producers. To better understand the spatial and temporal variability of frost, the occurrence and impact of frost events on rain-fed wheat production was estimated across the Australian wheatbelt for 1957-2013 using a 0.05 ° gridded weather data set. Simulated yield outcomes ...

Background: In Himalayas, particularly Jammu and Kashmir, where 85% of people depend on agriculture and allied sectors, 70% of agriculture is rain-fed. While the Himalayas, highly seismic, contribute highest in sediment transported to the world oceans, surface soil is under threat due to erosion, and Rajouri district in western Himalayas is no exception. Various factors, especially land use pat...

in this paper data were collected from 120 farmers in north khorassan province for the two periods (2005-2007) in order to survey the role of rain-fed lentil risk profile for designing an insurance model. to evaluate looses of each risk, risk frequency, risk impact criteria’s as well as risk matrix were used. results showed that low risk was the largest risk area. during study period, a decreas...

Different dietary cereal sources and fat types in the lactation diet were evaluated to investigate their effects on reproductive performance, milk composition, blood metabolites and hormones in multiparous sows. Twenty-four sows were randomly assigned to one of four treatments according to a 2×2 factorial arrangement of treatments. Each treatment had 6 replicates comprising 1 sow. Two cereal (c...
