This study was conducted to determine the chemical composition and nutritive value of sunflower residues silage (SRS) and effects of its substitution with alfalfa hay and corn silage on lactation performance, feed intake, nutrient digestibility and some blood parameters of Mohabadi dairy goats. Four experimental diets were formulated to gradually replace alfalfa hay and corn silage with SRS as ...
The purpose of this study was to determine the effects of supplementation of probiotic and peri-biotic supplements in dairy cows on quantitative and qualitative yield of milk, feed intake, digestibility of nutrients, and blood metabolites. Forty Holstein dairy cows with daily milk production of 37 ± 5 kg and initial weight of 700 ± 40 kg were divided into four groups in a completely randomized ...
The purpose of this study was to evaluate the effect of different levels of oil and soybean meal and Canola meal separately and mixed on productive performance, rumination and digestibility of nutrients in Holstein dairy cows. This research was carried out in a completely randomized design on 35 Holstein dairy cattle with 7 treatments and 5 cows with an average weight of 650 ± 40 kg. Treatments...
A sheep digestion trial and two feedlot trials with cattle were conducted to study effects of an ionophore, salinomycin, on nutrient digestibility, ruminal metabolism and cattle performance. In trial 1, addition of salinomycin at 5.5, 11 or 22 ppm to 60% concentrate diets fed to ruminal-cannulated rams had no effect (P greater than .05) on apparent digestibility of dry matter (DM), organic matt...
Aim: The present study was carried out to evaluate the nutrient digestibility of sweet sorghum stover, an unconventional roughage source in ram lambs in comparison to conventional sorghum and maize stovers. Materials and Methods: 18 Nellore ram lambs aged about 3 months (average body weight 15.65±0.10 kg) were randomly allotted to three complete rations formulated with roughage to concentrate r...
Solid-state (13)C nuclear magnetic resonance (NMR) and elemental analysis techniques were used to monitor the degradation of wheat bran by the white-rot fungus Pleurotus ostreatus during a 62-day cultivation period. The weight loss and in vitro organic matter digestibility of the substrate were also evaluated after fungal treatment. The (13)C NMR spectra of degraded wheat bran samples showed a ...
This study was done to investigate the nutritive value of Festocaovina, Agrostisgiganta and Avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. Rumen and feces liquor were collected from three fistulated sheep. Rangeland species sampling was randomly conducted from different areas of Guilan province. All the collected samples were initiall...
Extended Abstract Introduction and Objective: The most important factor in adjusting poultry feed consumption is energy, which is correlated with feed cost. The net energy system is more accurate and useful for measuring the energy utilization of poultry. The presence of anti-nutritional compounds such as non-starch polysaccharides (NSPs) and phytate compounds in some poultry feed items ...
the aim of this study was to investigate the effect of feeding of steeped barley grain with lactic acid (la) and citric acid (ca) on dry matter intake, feeding behavior, apparent nutrients digestibility, rumen ph and milk production. eight early lactating holstein cows in the second parities were used in 4×4 latin square change- over design. treatments consisted of basis diet containing 1) dr...
In this study the effects of different levels of raw and autoclaved rice bran (0, 6, 12 or 18%) on the growth performance, carcass parameters, internal organs and the nutrients digestibility were assessed. This experiment was designed on 420 fourteen-day-old male broilers (Ross 308). Birds were randomly divided into 7 treatment groups and 3 replications, each with 20 birds. Treatments were: 1= ...
