ВЛИЯНИЕ НА СРОКА НА СЪХРАНЕНИЕ НА РАЗПЛОДНИТЕ ЯЙЦА ВЪРХУ ИНКУБАЦИОННИТЕ ПОКАЗАТЕЛИ ПРИ ЯПОНСКИ ПЪДПЪДЪЦИ
No full textThe purpose of the present study was to establish the effect of the prolonged storage of Japanese quail hatching eggs upon the incubation performance and the quality of hatched quail chicks.
The duration of egg storage prior to their incubation had a weak negative effect on the weight loss from incubation day 0 to day 15. Eggs stored for 1-3 days exhibited a statistically signifi cantly higher weight loss than eggs stored for 8-11 days prior to incubation (PЦелта на настоящото проучване е да провери влиянието на продължителното съхранение на разплодните яйца от Японски пъдпъдъци върху резултатите от инкубацията и качеството на излюпените пъдпъдъци. Продължителността на съхранение на яйцата преди инкубацията оказва слаб, отрицателен ефект върху
загубата на маса през инкубационния период от 0 до 15 дни. Загубата на маса при яйцата, съхранявани 1-3 дни е достоверно по-висока от тази при яйцата, съхранявани 8-11 дни преди инкубацията (
ВЛИЯНИЕ НА ЗАМЯНАТА НА ТРУПНО БРАШНО ВЪВ ФУРАЖНАТА СМЕСКА С БРАШНО ОТ КАКАВИДИ НА КОПРИНЕНАТА ПЕПЕРУДА (BOMBYX MORI L.) ВЪРХУ РАСТЕЖА НА ЯПОНСКИТЕ ПЪДПЪДЪЦИ
No full textA study is carried out with two groups of japanese quails in order to check the possibility to substitute cocoon meal (B.mori L.) for meat meal as well as to evaluate a growth potential in these conditions. The forage mixture of control group contains 7% meat meal. The experimental forage mixture contains 7% cocoon meal and has equal nutritive value. The substitution of meat meal with the cocoon meal in quails food results in better growth development during
first days of their life. Both sexes have higher body weight - 11.1%; 8.7% and 9.8% respectively in 7th, 14th and 21 day of life. Feed conversion ratio (FCR) during the period from 0 to 35th day as well as the fi nal body weight of birds in two groups is equal. The cocoon meal can be the suitable constitutor in starter forage mixture for quails guaranteed equivalent growth and FCR.Проведено е проучване с две групи японски пъдпъдъци с цел да се установят възможностите за заместване на трупното брашно с брашно от какавиди на копринената пеперуда (Bombyx mori L.) и да се оценят растежните способности на пъдпъдъците при това. Фуражната смеска на контролната група съдържаше 7% трупно
брашно, а на опитната - 7% какавидено, при еднакъв хранителен състав. Заместването на трупното брашно с какавидено в смеските за пъдпъдъци е свързано с по-добро тегловно развитие на птиците през първите дни от живота им. Общо за двата пола живото тегло на птиците от опитната група е било достоверно по-високо с 11,1; 8,7 и 9,8% съответно на 7-, 14- и 21-дневна възраст. Конверсията на фураж за периода 0-35 дни, както и
крайното живо тегло на птиците от двете групи са практически еднакви. Какавиденото брашно може успешно да замени трупното в стартерните смески за пъдпъдъци, като гарантира равностоен растеж и конверсия на фуража

INFLUENCE OF HATCHING EGGS STORAGE PERIOD UPON THE INCUBATION PARAMETERS IN JAPANESE QUAILS
No full textThe purpose of the present study was to establish the effect of the prolonged storage of Japanese quail hatching eggs upon the incubation performance and the quality of hatched quail chicks. The duration of egg storage prior to their incubation had a weak negative effect on the weight loss from incubation day 0 to day 15. Eggs stored for 1-3 days exhibited a statistically signifi cantly higher weight loss than eggs stored for 8-11 days prior to incubation (P<0.001). Eggs stored for up to 8 days showed a tendency towards statistically signifi cant (P<0.05) longer period of incubation. The relationship between incubation period length and egg storage term was moderate, curvilinear and the effect of egg storage term was estimated at 14.3% оf the total dispersion of the trait. Despite the egg storage term prior to incubation, quails with high relative weight had a statistically signifi cant shorter period of incubation. The analysis of the combined effects of egg storage term and relative weight at hatching on incubation length showed that both factors complemented each other and even enhanced their effects upon the determination of the studied trait. The strength of these factors’ effects was estimated at 13.1% of the total dispersion of the incubation period length (P<0.001), with a leading role of the factor relative weight of hatched quail chicks
Methods for introduction of objective criteria for bioconversion of energy and nutrients along the feed-animal products chain in meat-type poultry farming
No full textThe authors propose a new approach for the determination of the conversion of energy and nutrients from the consumed feed (primary unit) to animal products (secondary unit). For this purpose, specific criteria for the conversion of energy and nutrients (“Clarke of distribution of the energy” and “Clarke of transformation of the protein/amino acids”) are introduced, so as an exemplary methodology for their calculation is shown. In the model calculations data from real experiments with Japanese quails are used. Although the proposed criteria are not economic, the authors suggest that their input will be a good basis for selection and technology assessment in the meet poultry breeding
Practical Points-to Analysis for Programs Built with Libraries
No full textTraditional whole-program analysis cannot be directly applied to programs that include precompiled libraries. Such programs could be analyzed separately from the included libraries by using precomputed summary information about each library. This paper describes one such separate analysis derived from Andersen’s whole program points-to analysis. The analysis uses a summary which is a compact representation of the points-to effects of all statements in the library. The summary is generated by substituting some of the library variables with placeholder variables. By replacing many variables with the same placeholder, we can reduce the size of the summary and the cost of the separate analysis. We use a substitution which summarizes the library effects without losing precision or exposing the internals of the library. Our experiments show that the cost of computing and storing the summary is practical, and that the substitution technique significantly reduces the cost of the separate analysis.Technical report DCS-TR-41
Points-to and Side-effect Analyses for Programs Built with Precompiled Libraries
No full textLarge programs are typically built from separate modules. Traditional whole-program analysis cannot be used in the context of such modular development. In this paper we consider analysis for programs that combine client modules with precompiled library modules. We define separate analyses that allow library modules and client modules to be analyzed separately from each other. Our target analyses are Andersen's points-to analysis and a side-effect analysis based on it. We perform separate points-to and side-effect analyses of a library module by using worst-case assumptions about the rest of the program. We also show how to construct summary information about a library module and how to use it for separate analysis of client modules. We present empirical results showing that the separate points-to analyses are practical even for large modules, and that the cost of constructing and storing library summaries is low. Our work is a step toward incorporating practical points-to and side-effect analyses in realistic compilers and software productivity tools.Technical report DCS-TR-42
Points-to analysis for Java based on annotated constraints
No full textThe goal of points-to analysis for Java is to determine the set of objects pointed to by a reference variable or a reference object field. In this paper we present a points-to analysis for Java based on Andersen’s points-to analysis for C [5]. Andersen’s analysis can be implemented efficiently by using systems of set-inclusion constraints and by employing several techniques for constraint representation and resolution. We extend these techniques to efficiently represent and solve systems of annotated inclusion constraints. The annotations play two roles in our analysis. Method annotations are used to model precisely and efficiently the semantics of virtual calls. Field annotations allow us to distinguish between different fields of an object. In addition, our analysis keeps track of all reachable methods and avoids analyzing irrelevant library code. We evaluate the performance of the analysis on a large set of realistic Java programs. Our experiments show that the analysis runs in practical time and space, and has significant impact on call graph construction, virtual call resolution, synchronization removal, stack-based object allocation, and object read-write information. The results show that our analysis is a realistic candidate for a relatively precise, practical, general-purpose points-to analysis for Java.Technical report DCS-TR-42
Precise Call Graph Construction in the Presence of Function Pointers
No full textThe use of pointers creates serious problems for optimizing compilers and software engineering tools. Pointers enable indirect memory accesses through pointer dereferences, as well as indirect procedure calls (e.g., through function pointers in C). Such indirect accesses and calls can be disambiguated with pointer analysis. In this paper we evaluate the precision of a pointer analysis by Zhang et al. [17] for the purposes of call graph construction for C programs with function pointers. The analysis uses an inexpensive, almost-linear, flow- and context-insensitive algorithm. To measure analysis precision, we compare the call graph computed by the analysis with the most precise call graph obtainable by a large category of pointer analyses. Surprisingly, for all our data programs the analysis from [17] achieves the best possible precision. This result indicates that for the purposes of call graph construction, even inexpensive analyses can provide very good precision, and therefore the use of more expensive analyses may not be justified.Technical report DCS-TR-44
