Vo, Kieu Van (Texas A&M University. Libraries, 1981)Feeding 20 min/6 hrs or skip-a-day feeding resulted in a significant reduction in live weight and carcass weight at market age. Compensatory growth during the period of re-alimentation was observed to be greatest in birds ...
-
Benibo, Benibo Sinny (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 ...

The effect of energy phase feeding, cage size and bird density on performance of commercial layers Coligado, Elpidio Comendador (Texas A&M University. Libraries, )
-
Brooks, Leon George (Texas A&M University. Libraries, 1986)A study was conducted to determine the effects of increasing dietary pre-lay calcium levels from 1.00 to 2.00 or 3.00% between 15, 17 or 19 weeks of age. A total of 840 Single Comb White Leghorn pullets were randomly ...
-
The effect of perches, toe clipping, population and bird density on the performance of cage layers Ruszler, Paul Leland (Texas A&M University. Libraries, 1970)Studies were conducted to determine the effects of populations of birds per cage and floor area per bird (density) on the economic and productive performance of cage layers. Perches were placed in the cages of certain high ...
-
Koelkebeck, Kenneth Willia (Texas A&M University. Libraries, 1984)The objectives of this study were to provide better standardized procedures for determining relationships between stress (or the lack of it) and well-being for laying hens maintained in different management alternatives. ...
-
Bastien, Robert Wilfred (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 ...
-
Valera, Juan (Texas A&M University. Libraries, 1971)Several humidity studies and incubation trials were conducted in plastic chambers to determine the effect of substituting helium for nitrogen in the atmosphere of developing chicken embryos and to determine optimal conditions ...
-
Gonzalez-Delfino, Andres (Texas A&M University. Libraries, [1971])Two studies were conducted to determine the effects of soybean meal (SBM), sesame meal (SM) and glandless cottonseed meal (GCSM) upon performance of inbred-cross layers. In the first experiment, two strains of birds (180 ...

Hargis, Phillip Herbert (Texas A&M University. Libraries, 1980)Four experiments were conducted with Indian River broiler chicks in which the protein and energy levels were fed in different combinations in an attempt to produce a broiler at 49 days of age with reduced body fat while ...
-
Brister, Roy David (Texas A&M University. Libraries, 1985)Two experiments were conducted with commercial egg-type laying hens to determine the effects of housing body weight and parental egg weight on egg quality and laying hen performance. In experiment 1, egg production improved ...
-
Murthy, Pinapaka Venkata Lakshmi Narasimha (Texas A&M University. Libraries, 1969)Two experiments using commercial incrossbred pullets, 22 weeks of age, were conducted. In experiment No. 1 the results on performance of two levels of added choline chloride (400 and 1600 Gms/ton), B₁₂ (4 and 16 milligrams/ton) ...

Mahmoud, Mohamed Hanafi Sayed (Texas A&M University. Libraries, 1966)A 2 x 2 x 2N confounded diallel mating design (2 series, 2 males, N females per male per series) was used to obtain estimates of the genetic parameters in body weight traits in a noninbred population of New Hampshire ...
-
Santana, Jose (Texas A&M University. Libraries, 1973)New ingredients for poultry feed formulation were evaluated. The first study was undertaken to determine the performance of laying hens when fed inorganic sulfate, and to determine a possible sparing effect of inorganic ...
-
Campos, Egladson Joao (Texas A&M University. Libraries, 1973)Hatching egg production from commercial broiler breeders housed in single and multiple male cages maintained in a naturally and in artificially ventilated houses was investigated. Twelve cages measuring 90x90x60 cm. and ...

Ali, Nahil Mohammed (Texas A&M University. Libraries, 1977)A closed population of White Leghorns was used in this study to evaluate the importance of additive and nonadditive genetic variance in the inheritance of egg yolk and blood serum cholesterol in chickens. A diallel mating ...
