Calcium and phosphorus requirements of breeding bobwhite quail.
نویسندگان
چکیده
egg production is lowered, with the eggshells becoming pro gressively thinner. The serum calcium of the hen falls and there is a depletion of the calcium and phosphorus contents of the bones. Nevertheless, according to Branion, the percentage composition of the shell remains constant, showing that, as in bone formation, if the mineral is deposited, it is laid down in the normal proportion. Deobald et al. ('36) concluded that

Studies on the sodium, chlorine and iodine requirements of young pheasants and quail.
Previous studies from this laboratory have dealt with the protein, calcium, phosphorus, vitamin D, manganese, zinc, riboflavin, niacin and choline requirements of pheasants (Scott, et al., '54, '58a, '59) . The phosphorus requirements of young Bobwhite quail also have been reported (Scott, et al., '58b). Although many studies have been made on the effects of various levels of salt in rations fo...
متن کاملQuail Management: Issues, Concerns, and Solutions for Public and Private Lands— a Southeastern Perspective
In the Southeastern United States, Breeding Bird Surveys that bobwhite populations have been declining at 3.8%/year over the last 3 decades. Declines have been attributed the cumulative effects of large-scale deterioration of quail habitat quality associated with advanced succession, intensive monoculture farming, and intensive timber management. Additional factors such as changing role of pred...
متن کاملExamination of the dietary methionine requirements of breeding northern bobwhite, Colinus virginianus.
Adult Northern bobwhite were used to test the hypothesis that dietary methionine levels recommended by the NRC for breeding quail are excessive for wild bobwhite. We tested the hypothesis by comparing immunocompetence, reproductive performance, and chick viability of Northern bobwhite hens fed diets containing low (0.31%), moderate (0.39%), or high (0.47%) concentrations of methionine. Chick vi...
متن کاملInfluence of Phytase on Tibia Bone Characteristics of Broiler Quail Fed on Corn-Soybean Meal Diets
BACKGROUND: Exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. OBJECTIVES: In the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. METHODS: In a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. All birds received one of four experimen...
متن کاملAnnotated Draft Genome Assemblies for the Northern Bobwhite (Colinus virginianus) and the Scaled Quail (Callipepla squamata) Reveal Disparate Estimates of Modern Genome Diversity and Historic Effective Population Size
Northern bobwhite (Colinus virginianus; hereafter bobwhite) and scaled quail (Callipepla squamata) populations have suffered precipitous declines across most of their US ranges. Illumina-based first- (v1.0) and second- (v2.0) generation draft genome assemblies for the scaled quail and the bobwhite produced N50 scaffold sizes of 1.035 and 2.042 Mb, thereby producing a 45-fold improvement in cont...
