Metabolism of dehydroretinyl ester in White Leghorn chicks.
1. The metabolism of dehydroretinyl ester has been studied in vitamin-A-deficient white leghorn chicks. Dehydroretinyl ester was metabolized to 3-hydroxyretinol diester, 3-hydroxyanhydroretinol and rehydrovitamin A2 which were isolated from the intestines and livers of chicks. 2. The metabolism of 3-hydroxyretinol diester and 3-hydroxyanhydroretinol, which were immediate metabolites of dehydror...
متن کاملShort Copy Number Variations Potentially Associated with Tonic Immobility Responses in Newly Hatched Chicks
INTRODUCTION Tonic immobility (TI) is fear-induced freezing that animals may undergo when confronted by a threat. It is principally observed in prey species as defence mechanisms. In our preliminary research, we detected large inter-individual variations in the frequency and duration of freezing behavior among newly hatched domestic chicks (Gallus gallus). In this study we aim to identify the c...
متن کاملStudy on Reproductive Traits of Barred Plymouth Rock and White Plymouth Rock Parent Stock (Female Breeders) in the Humid Zone of Nigeria
The study was carried out to assess the reproductive abilities of White Plymouth Rock (WPR) and Barred Plymouth Rock (BPR) parent stock (layer breeders) reared under similar housing (deep litter), management and agro-climatic conditions. A total of 1,763,322 and 1,732,966 fertilized eggs were produced by WPR and BPR, respectively, during the observed period which lasted four years (2002-2005). ...
متن کاملLong-term divergent selection for eight-week body weight in white Plymouth rock chickens.
This paper provides an overview of results from a long-term (38 generations) selection experiment. Lines were developed from individual phenotypic selection for high or low body weight at 8 wk of age. Included are data for the selected lines, sublines in which selection was relaxed, crosses of the selected lines, and sublines in which the sex-linked dw gene was introduced. Periodically (and in ...
متن کاملEffect of genetic selection on growth parameters and tonic immobility in Leghorn pullets.
Four genetic stocks of Leghorn pullets were used to evaluate the effects of genetic selection on growth and fearfulness behavior. Three of the stocks were the Ottawa randombred control stocks from 1950 (CS5), 1959 (CS7), and 1972 (CS10). The fourth stock was a 1993 commercial laying stock (CCS) whose ancestors were involved in the formation of the randombred control stocks. Pullets were reared ...
