The livestock and poultry industry is facing numerous challenges to keep up with the increasing demand for high quality animal protein due to the continuously increasing global human population, severe drought conditions around the world, and grains being used for ethanol production. Since feed costs are the majority of the total cost required to produce a live bird, feed efficiency (FE) is a t...
This study was conducted to investigate the effect of fenugreek and copper sulfate supplementation levels and their combinations in diets on productive, physiological performance, lipids profile in blood, liver or yolk, fertility and hatchability of Japanese quail for a period of 7 weeks (from 8 to 14 weeks). A total number of 162 mature Japanese quail birds were used in this study. Quail birds...
We conducted 2 consecutive experiments to verify whether adult captive Greater rheas (Rhea americana) could select diets differing in nutritional and energetic content, and to evaluate the effect of those diets on egg production and hatchability. From August to January, animals were offered four diets: processed feed for rheas (diet 1), diet 1 + soybean (diet 2), processed feed for chicken (die...
Both chicken meat and egg is excellent foodstuff due to their compositions of amino acids, monoand polyunsaturated fatty acids and vitamins. There is evidence that functional feed ingredients can improve the meat yield and egg quality (Patten and Waldroup, 1988; Izat et al., 1991; Mahfudz et al., 1996). In this study, we examine the effect of feed ingredients such as ethanolic extract of shochu...
background: we studied the possible advantages of feed-forward control nursing model in the treatment of placenta previa. methods: we enrolled 60 pregnant women who were receiving treatment for expectant placenta previa between january 2010 and january 2016 and randomly divided them into the control group and the observation group with 30 cases in each group. in the control group, we offered sp...
The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. Data on egg production, feed conversion (kg feed intake/ kg eggs and dozen eggs), egg weight, egg specific gravity, eggshell thickness and weight, Haugh unit, yolk index, albume...
this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...
Ether extract composition of poultry by-product meal (PBM) varies among feed-grade and pet food-grade sources. Because feed-grade PBM contains a wider variety of processing residues than pet food-grade PBM, it is presumed to be of lower fat quality (i.e., stability). This potential difference in fat quality, or stability, between PBM sources can be accentuated by high environmental temperatures...
Preventing leg disorders in broilers, without changing their body weight at slaughter age and their rearing time is a challenge for poultry production. The method of prevention we studied consisted in alternating the distribution of different diets. This kind of diet schedule is called “sequential feeding”. The alternation of poorand rich-lysine diets was used in order to reduce early growth an...
This paper focuses on steady state performance predictions and optimization of the Reverse Osmosis (RO) process utilizing a set of implicit mathematical equations which are generated by combining solution-diffusion model with film theory approach. The simulation results were compared with operational data which are in good agreement having relative errors of 0.71% and 1.02%, in terms of water r...
