The scarcity and increase in the price of animal feeds have attracted attention nutritionists to address this issue. inclusion plant extracts enzymes protein-reduced diet could be a feasible strategy reducing feed cost. Therefore, purpose study was assess impacts Yucca schidigera extract multi-carbohydrase low crude protein (CP) diets broiler on growth performance, nutrient digestibility, carca...

I . Diets containing varying lcvels of crude protein (CP) in the range 9.5-18.5 "/b with and without supplements of diammonium citrate (DAC) as a source of non-protein nitrogen (KPN) were given to 160 growing chicks from z to 4 weeks of age, and their livers were assayed for glutamate dehydrogenase (GDH) activity. 2. Growth rate and total liver protein were increased by raising the protein leve...

This study was conducted to determine the nutritional (proximate and energy) composition of selected shea nut by-products (SNPs) namely; shea nut meal (SNM, solvent extracted), shea nut cake (SNC, mechanically extracted) and shea nut cake (SNCW, water extracted) and their apparent digestibility coefficient (ADC) by Nile tilapia, Oreochromis niloticus. The ADC was determined using a reference di...

Most models developed for poultry are linear to the point where genetic potential is reached. Models reliant on the premise that growth rate determines requirements based on some fixed rate of nutrient utilization do not adequately represent the biological phenomena involved. Therefore, a dichotomy between the accepted theories of nutrient utilization in animals and the assumptions of mathemati...

In this study the enrichment dietary effect with different crude protein levels (CP) and feed additives on growth, survival, conversion ratio (FCR), consumption (FC) total hemocyte count (THC) in juvenile white shrimp Litopenaeus vannamei were evaluated. The covered two bioassays: first one, juveniles daily fed for 45 days four experimental diets containing: (1) Control, commercial (35% CP); (2...

Two experiments to determine the crude protein (CP) requirement of Heros severus were performed. Five isocaloric (3,200 kcal kg−1 digestible energy) diets containing five levels CP (28, 32, 36, 40, and 44%) evaluated. In first, 75 fingerlings distributed among 15 aquaria (30 L). second experiment, 100 juveniles 20 (50 A quadratic effect on weight gain, specific growth rate for length, feed inta...

Two trials were conducted to evaluate the effect of xylose treatment on rumen degradability characteristics of DM, OM and CP and in vivo digestibility of DM, OM, CP and crude fiber (CF) of soybean meal (SBM) and cottonseed meal (CSM). In Trial 1, three ruminally cannulated Merino rams were used. Xylose treatments at both levels, 0.5 and 1%, decreased effective degradability of DM, OM and CP of ...

The goal of this study was to evaluate the effects of dosing unadapted lambs with tannin-tolerant bacteria to improve the digestibility of a high condensed tannin (CT) diet. During the initial phase (metabolism study), a diet containing 30% peanut skins was fed to two groups of Suffolk FinnDorset ram lambs that were about three months old and weighed an average of 24.2 1.4 kg. All animals recei...

In this study, we compared an innovative stripping technique with a conventional whole plant harvesting for alfalfa and red clover to develop approach regional production of proteins amino acids. While the stems were harvested separately, leaves fractionated by them from using prototype machine, which resulted in higher crude protein (CP) acid yield (CP 26.53% dry matter (DM), g/kg DM, Lys 16.2...
