(Texas A&M University. Libraries, 1978)Economy of egg production is greatly affected by the quality of the egg shell and its ability ot withstand shock and resist breakage. The egg industry loses no less than 250 million dollars annually because of egg breakage ...
-
(Texas A&M University. Libraries, 1987)Fifteen crosses of day-old Shaver Single Comb White Leghorn egg-type chicks were used to study the effect of early protein restriction on growth and subsequent performance during lay. Four dietary protein regimes ...
-
(Texas A&M University. Libraries, 1979)Two hundred and sixteen hens were divided into six treatment groups, each consisting of three replicates of twelve Single Comb White Leghorn hens, housed two birds per cage, in a study to determine the effects of dietary ...

(Texas A&M University. Libraries, 1992)Four experiments are reported to explain some of the endogenous factors and mechanisms which confer resistance to Salmonella enteritidis (SE) infectivity in the intestinal tract of Leghorn chicks: (A) The effects of 14 or ...
-
(Texas A&M University. Libraries, 1990)This study examined the antiviral, adjuvant and immunomodulatory effects of acemannan (ACE-M), a long-chain polydispersed β-(1,4)-linked mannose polymer. Antiviral effects were determined in vitro. Newcastle disease virus ...
-
(Texas A&M University. Libraries, 1987)The objective of the first experiment was to determine if thermal stress directly affects the endocrine regulation of ovulation. Hens were acutely heat stressed to limit the indirect effect of reduced feed consumption on ...
