Estimates of genetic parameters for carcass, growth and reproductive traits in Nellore cattle
(2013-07-01)
The objective of this study was to estimate genetic parameters for female mature weight (FMW), age at first calving (AFC), weight gain from birth to 120 days (WG_B_120), from 210 to 365 days (WG_210_365), rib eye area ...
Genome-wide association study for backfat thickness in Canchim beef cattle using Random Forest approach
(2013-06-05)
Background: Meat quality involves many traits, such as marbling, tenderness, juiciness, and backfat thickness, all of which require attention from livestock producers. Backfat thickness improvement by means of traditional ...
Relação entre medidas ultrassônicas e da carcaça de bubalinos Murrah abatidos em diferentes períodos de confinamento
(Sociedade Brasileira de Zootecnia, 2009-09-01)
Os objetivos neste trabalho foram estimar as correlações entre medidas obtidas por ultrassonografia e na carcaça e acompanhar o desenvolvimento da área de olho-de-lombo e a deposição de gordura de búfalos em diferentes ...
Whole-genome analysis for backfat thickness in a tropically adapted, composite cattle breed from Brazil
(Wiley-Blackwell, 2012-10-01)
Backfat thickness affects the preservation of the beef carcass after slaughter and confers organoleptic characteristics assessed by the consumer. One of the breeding goals for Canchim, a tropically adapted breed, is to ...
Genetic and environmental factors affecting ultrasound measures of longissimus muscle area and backfat thickness in Nelore cattle
(Elsevier B.V., 2008-09-01)
The aim of the present study was to evaluate the genetic and environmental factors affecting records of longissimus muscle area (LMA) and back fat thickness (BF) obtained between the 12th and 13th ribs, and rump fat thickness ...
Morpho-physiological analysis of the insect fat body: A review
(Pergamon-Elsevier B.V. Ltd, 2010-07-01)
The insect fat body is the main organ of the intermediate metabolism of insects. The majority of proteins of the haemolymph is synthesized in this tissue, which also presents the functions of lipids, carbohydrates and ...
Genetic analysis on growth and carcass traits in Nelore cattle
(Elsevier B.V., 2012-07-01)
In this study, the objective was to estimate genetic parameters of body weight at 210 (BW210) and 365 (BW365) days of age in relation to rib eye area (REA), subcutaneous back fat thickness (BF) and rump fat (RF), and their ...
Crescimento dos tecidos muscular e adiposo de fêmeas bovinas de diferentes grupos genéticos no modelo biológico superprecoce
(Sociedade Brasileira de Zootecnia, 2010-03-01)
Objetivou-se avaliar o crescimento de novilhas de diferentes grupos genéticos no sistema de produção superprecoce. Utilizaram-se 132 novilhas dos seguintes grupos genéticos: 18 ¾ Canchim × ¼ Nelore (¾ CN); 18 ½ Canchim × ...
Comparison of skinfold thicknesses and bioelectrical impedance analysis with dual-energy X-ray absorptiometry for the assessment of body fat in patients on long-term haemodialysis therapy
(Oxford Univ Press, 2003-01-01)
Background. Body composition assessment in patients with chronic renal failure is of paramount importance since studies have demonstrated the association of protein-energy malnutrition with an increased morbidity and ...
