Determination of forage quality of plant species in natural habitats such as rangelands and deserts is one of the most important factors for grazing management of these ecosystems. For this purpose, the nutritional values of Calligonum comosum in three phenological stages (vegetative growth, flowering, and seedling) were determined in desert habitats located in the northeast of Kashan, Iran (in...

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P

Using nylon bag techniques, Cornell net carbohydrates and protein systems (CNCPS), scanning electron microscopy, the authors examined digestibility structure of Vicia ervilia (ervil, bitter vetch) after steam flaking, roasting, microwave processing. During in situ technique, samples were incubated at 0, 2, 4, 6, 8, 12, 16, 24, 36, 48 h. For description ruminal DM (dry matter) CP (crude protein)...

Ruminal and abomasal cannulated mature wethers were fed 800 g daily of low quality bermudagrass (49 days of age, containing 8.6% crude protein) and used in a 4 x 4 latin square experiment to study the effects of different protein supplements on the daily quantity of protein and amino acids reaching the abomasum and on rumen microbial protein synthesis. Treatments were as follows: (1) control (l...

In order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from Cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. Treatments were the diets as follow: 1) diet for...

this study was conducted to investigate the effect of physical and chemical processing on crude protein fractions of two varieties of canola (okapi and modena) and safflower (62 and zarfan) seed using cornel net carbohydrate and protein system and on protein subunits using sodium dodecyl sulfate polyacrylamide gel electrophoresis. formaldehyde was used as chemical treatment, while toasting and ...

the effects of l-carnitine on growth performance and carcass composition in male broiler chicks, fed diet in which cp was reduced in a stepwise manner from 21 to 18% were investigated. ileal digestible quantities of all eaa were almost equal in the diets, with quantities nrc 1994 recommendations. one hundred forty four male commercial broilers were allotted to six groups, each with four replica...

Weaning transition is often associated with the occurrence of post-weaning diarrhoea syndrome (PWDS). The reduction dietary crude protein (CP) has been intensively used as a strategy for con...

The aim of this research is to compare indigestible internal markers acid insoluble ash (AIA) and acid detergent lignin (ADL) and total collection of faeces (TCF) for apparent digestibility estimation in Caspian horse. Analyses were carried out on wheat straw, alfalfa, barley and maize, for dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (ND...
