to investigate the effect of two dietary levels of l-carnitine and vegetable fat powder on the quality of cockerels' sperm and broiler breeder fertility and hatchability. two hundred and fifty female and twenty five male broiler breeders. were studied classic hubbard parent stocks were randomly distributed in five groups of 50 with five replicates of 10 females and one male. two levels of ...

Raper and Fennell (1953) studied heterokaryon formation in Aspergillus fonsecaeus Thom and Raper, strain NRRL 67, a carbonaceous black species of the Aspergillus niger group (Thom and Raper, 1945) which produces large multinucleate conidia. Eleven various color, nutritional and morphological mutants (figure. 1) were produced by ultraviolet irradiation of the wild strain. The mutants were paired...

The effect of genetic strain (Ross 308; Cobb 500) and parent flock age (Ross at 32 and 36 weeks; Cobb at 26 and 44 weeks of age) on hatchability, fertile hatchability, Egg Weight Loss (EWL) and egg break out analysis were examined. At each flock age, 300 eggs from each treatment group were incubated. Thirty eggs from each treatment group were labeled individually for the measurements of Egg Wei...

Recent research has documented empirical evidence of informed trading ahead of major corporate events such as earnings announcements, mergers and acquisitions (M&A) and corporate bankruptcies. Surprisingly, however, no such evidence exists ahead of corporate divestiture or spinoff (SP) announcements. This is noteworthy because the parent company’s stock usually experiences a significant price j...

Among clinicians, it is common practice to include parents in treatment, and it has been taken for granted that parents' involvement in their children's treatment is beneficial for therapy outcome, although research on this issue is far from clear. A meta-analysis was carried out in order to investigate whether parent involvement potentiates the outcome for children with anxiety disorders when ...

This paper introduces a framework for a knowledge-based memetic algorithm, called KBMA. The problem of stock classification is the test bed for the performance of KBMA. Domain knowledge is incorporated into the initialization and reproduction phases of evolutionary computation. In particular, the structure of financial statements is used to sort the attributes, which contributed to a faster con...

The metacyclic trypanosomes of a Trypanosoma brucei brucei clone (ILTat 2.1) were analysed with regard to their variable antigen (VAT) composition using monoclonal antibodies. The metacyclic population was antigenically heterogeneous. Despite the heterogeneity, however, the overall VAT composition of the metacyclic population appeared to be limited in number. A similar pattern of reactivity was...

Salah satu komoditi penyebab inflasi di kota Ambon adalah daging ayam broiler/pedaging. Hal ini terjadi karena banyaknya permintaan broiler (pedaging) sedangkan penawaran (produksi) hanyalah sedikit, menunjukan bahwa ketika akan suatu barang naik dan jumlah yang diminta itu sedikit maka memicu naiknya harga pasar menyebabkan salah cara untuk menekan laju inflasi, beku didatangkan dari luar daer...

Chloropolysporins A, B and C, as well as derivatives prepared from this group and alpha- and beta-avoparcins by enzymatic and mild acid hydrolysis, were active against Gram-positive bacteria including clinically isolated methicillin-resistant Staphylococci (MIC 0.39-6.25 micrograms/ml) and anaerobic enterobacteria (MIC 0.10-1.56 micrograms/ml). Derhamnosyl and demannosyl derivatives from both g...

To investigate feed as a source for fluoroquinolone-resistant Escherichia coli in broiler chickens, we compared antimicrobial drug-resistant E. coli from broiler feed and broilers with ciprofloxacin-resistant human clinical isolates by using pulsed-field gel electrophoresis. Feed was implicated as a source for ciprofloxacin-resistant broiler-derived E. coli and broilers as a source for ciproflo...
