Abstract:
It has been known that the chicken’s resistance to disease was affected by chicken’s genetic background. And RLR-mediated antiviral pathway plays an important role in detection of viral RNA. However, little is known about the interaction of genetic background with RLR-mediated antiviral pathway in chicken against MDV infection. In this study, we adopted economic line-AA broilers and native Erlang mountainous chickens for being infected with MDV. Upon infection with MDV, the expression ofMDA-5was upregulated in two-breed chickens at 4, 7, and 21 d.p.i. It is indicated that MDA-5 might be involv

Entrepreneurs are the main actors in economic development with their function as innovators or creators of new creations. Entrepreneurship has many types and fields, one of which is broiler farming. Broiler farming can be done using cages with open house and closed house types. Broiler farming has a relatively short maintenance time, there are three maintenance phases, namely the pre-stater phase, stater phase, and finisher phase. In order to produce quality chickens, farmers must know how to raise broilers properly and recognize the various diseases that can infect broilers. Broiler farming w

Abstract:
Feed accounts for the highest cost associated in poultry production, with energy-containing feedstuffs being the most expensive portion of the cost of feeding. The increasing demand for poultry meat gives reason to determine accurate apparent metabolizable energy (AME) values for various feedstuff through measuring energy utilization in the birds. The adaptation length of birds fed an experimental diet may affect the determined AME value due to the diet matrix and physiochemical properties of the feedstuff. Therefore, the objective of this thesis was to evaluate a select group of energy-contai

Abstract:
The effect of supplemental protease (Ronozyme ProAct) in broiler diet on the weights and percentage yields of slaughter by-products of male and female medium-growing Master Gris broiler chickens was analysed. Fattening period lasted for 63 days. Broilers were assigned to 3 experimental groups, each consisting of 100 birds. Experimental groups differed in protease levels used in their diets: control broilers (C) received complete feeds (starter, grower and finisher) without supplemental protease; chickens in the experimental group E-I were given a diet containing 0.2% protease and crude protein

Abstract:
Studies have been conducted on the use of surepny oilcake obtained from different varieties of Brassica rapa L., in the feeding of broiler chickens. The safe norms of its inclusion in the composition of balanced compound feeds have been determined. The enrichment of experimental compound feed with enzyme preparations increases the economic performance of broiler chickens. The oilcake surepny obtained from the seeds of the Brassica rapa L, selection of the All-Russion Williams Fodder Research Institute confirms the effectiveness of cultivation and the negative effect on broiler chickens.

Abstract:
The research conducted in our country and abroad has proven that any poultry farm that practices poultry floor management is affected by parasitic diseases, especially eimeriosis. The purpose of this study was to test the effectiveness of joint administration of the anticoccidial drug Diclazuril and the biogenic stimulant ASD against spontaneous coccidiosis in broiler chickens under production conditions. The effectiveness of joint administration of Diclazuril was tested on 1,739 floor management chickens aged 9 to 38 days, at a dose of 2 mL per 1 L of drinking water for 48 hours according to

Abstract:
The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo cond

Abstract:
: The necessity to improve broiler thermotolerance and performance led to the following hypothesis: (a) thethermoregulatory-response threshold for heat production can be altered by thermal manipulation (TM) during incubation so as to improve the acquisition of thermotolerance in the post-hatch broiler;and (b) TM during embryogenesis will improve myoblast proliferation during the embryonic and post-hatch periods with subsequent enhanced muscle growth and meat production. The original objectives of this study were as follow: 1. to assess the timing, temperature, duration, and turning frequency r

Abstract:
Background PHS (pulmonary hypertension syndrome, ascites syndrome) is a serious cause of loss in the broiler industry, and is a prime example of an undesirable side effect of successful genetic development that may be deleteriously manifested by factors in the environment of growing broilers. Basically, continuous and pinpointed selection for rapid growth in broilers has led to higher oxygen demand and consequently to more frequent manifestation of an inherent potential cardiopulmonary incapability to sufficiently oxygenate the arterial blood. The multifaceted causes and modifiers of PHS make

Abstract:
The necessity to improve broiler thermotolerance and live performance led to the following hypothesis: Appropriate comprehensive incubation treatments that include significant temperature management changes will promote angiogenesis and will improve acquisition of thermotolerance and carcass quality of heavy broilers through epigenetic adaptation. It was based on the following questions: 1. Can TM during embryogenesis of broilers induce a longer-lasting thermoregulatory memory (up to marketing age of 10 wk) that will improve acquisition of thermotolerance as well as increased breast meat yield
