Long necks enhance and constrain foraging capacity in aquatic vertebrates
(The Royal Society, 2017-11)
Highly specialized diving birds display substantial dichotomy in neck length with, for example, cormorants and anhingas having extreme necks, while penguins and auks have minimized necks. We attached acceleration loggers ...
Digestible methionine plus cystine requirements of ISA Label broilers reared in free-range system
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2009-05-01)
Three assays were carried out to determine the digestible methionine+cystine (Met+Cys) requirement for ISA Label broilers from both sexes. The birds were reared in free range system on starting phase (1 to 28 days), growing ...

Polymorphism analysis of the hsp70 stress gene in Broiler chickens (Gallus gallus) of different breeds
(Sociedade Brasileira de Genética, 2003-01-01)
The promoter region and the beginning of the coding region of the hsp70 stress gene were analysed in broiler chickens of a commercial breed (Hubbard-Pettersen), a breed selected for weight gain (PP1) and a non-selected ...
Serum biochemical parameters in the ring-necked pheasant (Phasianus colchicus) on breeding season
(2007-11-19)
The influence of sex on serum biochemical parameters was investigated in adult (52 week-old) ring-necked pheasants on reproductive activity. Statistical comparisons were made for differences in values between male and ...

Temporal variation in the abundance of two species of thrushes in relation to fruiting phenology in the Atlantic rainforest
(CSIRO Publishing, 2012-01-01)
When fruit resources in tropical forests are scarce, frugivorous birds might track fruiting by expanding their home-ranges or by moving. We tested whether the abundance of the Yellow-legged Thrush (Turdus flavipes) and ...
