Genetic Selection in Turkeys and Broilers And
Genetic selection in wild living animals favours a variety of different traits that are important for maintenance, and reproduction. In contrast selection in domesticated animals not only favours individuals that can cope best with the modified circumstances of living under human custody but also is artificially influenced by the needs of man, e. g. for fast growth or high reproductivity, but a...
متن کاملEffect of dietary fat and environment on lipogenesis by large white breeder turkeys.
An experiment was conducted to evaluate the effects of either a low-fat (8% of total calories) or high-fat (47% of total calories) diet on Large White breeder females maintained at a constant (21 C) or a cyclic temperature regimen (12 to 27 C). Each diet was fed to 32 hens individually caged in the cyclic condition and 46 in the constant condition. Energy consumption, reproductive performance, ...
متن کاملSexual Selection and the Genetic Mating System of Wild Turkeys
Molecular measures of parentage provide important insights into the opportunity for sexual selection; in birds, such studies have been conducted almost exclusively on pair-bonded passerines. Here I employ a multitiered parentage analysis involving 10-locus microsatellite genotypes to characterize the genetic mating system of a population of Wild Turkeys (Meleagris gallopavo), a promiscuous spec...
متن کاملHabitat Sampling and Habitat Selection by Female Wild Turkeys: Ecological Correlates and Reproductive Consequences
ABST•,Acr.--Habitat sampling can allow much more effective habitat selection for longterm activities such as nesting and may be directly linked to fitness. We studied the process of habitat sampling and selection in female Wild Turkeys (Meleagris gallopavo) in the Arkansas Ozarks. In particular, we tested the prediction that movements prior to selecting nesting habitat correlate with the qualit...
متن کاملDietary selection for lysine by piglets at differing feeding regimen
Article history: Received 14 August 2007 Revised 10 September 2008 Accepted 10 September 2008 The aim of the present study was to investigate preferences of piglets for diets varying in lysine (Lys) concentration andwhether those preferences are influenced by changing position of diets on offer in feeders. For this purpose, a feeding trial was carried out over a period of 5 weeks. Piglets (equa...
