this experiment was carried out for a determination of metabolizable energy and the effect of the grind multienzyme on in-vitro dry matter and protein digestibility in diets, and as well on performance of broiler chicks. a number of 800 day old unsexed arbor acres broilers were placed in 8 treatments and 4 replicates (25 chicks each). a completely randomized design (crd) of a factorial arrangem...
an experiment was conducted to study the effect of metabolizable energy (me) and protein of japanese quails diets on offspring performance and antibody production against sheep red blood cell (srbc). a total of 432 japanese quails (13 week-old) were divided into nine treatments. each treatment comprised four replicates of twelve birds (9 female and 3 male). nine diets including three levels of ...
The purpose of this study was to determine the contents of chemical compositions, apparent metabolizable energy (AME), apparent metabolizable energy corrected for nitrogen (AMEn), true metabolizable energy (TME), true metabolizable energy corrected for nitrogen (TMEn), in corn samples, as well as to predict diferrent energy contents of corn samples given their chemical components. A total...
The conceptual bases of recent NRC publications of nutrient requirements to meet dietary energy needs of growing Holsteins, emphasizing heifers gaining 0.75 kg/d, are described and compared with several world systems and with body composition data. Requirements of Holsteins for net energy for maintenance are generally thought to be higher (from 7 to 20%) than those of British beef breeds. Total...
The major consideration in this paper is the suitability of a metabolizable energy system for pigs. For poultry there is no practical alternative since urine and faeces are voided conjointly. The correction to digestible energy of a feedstuff for energy in urine is usually small, but there are circumstances when this may be large. Furthermore there are insufficient data on metabolizable energy ...
These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...
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 ...
this study was conducted to evaluate 13 promising triticale lines and cultivars based on yield traits, metabolizable energy and anti-nutritional compounds. the experiment was carried out using a rcb design with three replications at the seed and plant improvement institute, karaj and gonbad, during 2008-2009 cropping season. these genotypes were studied in the next year, at the animal science r...
this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...
