| The objective in this work was to evaluate the economicity of the finishing phase on feedlot of F1 Red Angus × Nellore (½ RA ½ N) and Blond D'Aquitaine × Nellore (½ BA ½ N) crossbred young bulls slaughtered at 480, 520 and 560 kg of body weight. Thirty-six F1 crossbred young bull with 20 months of initial average age: 18 ½RA½ N and 18 ½N½ BA were allotted to a completely randomized design in a 2 × 3 factorial arrangement (genetic group × slaughter weight), with six replicates. The ½ BA ½ N young bulls slaughtered at 480 kg had the highest carcass gain (kg/day), feed efficiency, gross income (R$/day), gross profit of feed (R$/day), break-even cost of the diet (@/t DM) and cost:benefit ratio. The ½ BA ½ N young bulls also had higher dressing percentage than... |

| 'Kalveren bij de koe' is een heel aaibaar concept om dierenwelzijn te bevorderen. Het project was de afgelopen jaren goed voor veel aandacht. Het principe lijkt simpel , maar in de praktijk komt er veel bij kijken om succesvol kalveren bij de moeder op te fokken. In dit BioKennisbericht ervaringen van 'Kalveren bij de Koe' - boeren uit de periode 2009 tot 2011, en de vraag of de biologische landbouw met dit concept voldoende onderscheidend kan zijn. |

| Kann man von einer speziell biologisch-dynamischen Rindviehzucht sprechen? Eine Grundlage und zugleich ein Ziel biologisch-dynamischer Arbeit ist ein Umgang mit den Tieren und Pflanzen, mit dem Boden und der Landschaft, welcher diesen Lebewesen und Lebensräumen in ihrer Charakteristik und ihrer Eigenart gerecht wird und sie fördert. Nicht wirtschaftliche oder arbeitstechnische Überlegungen stehen im Vordergrund, sondern das Tier selbst, die Pflanzenart selbst, die Bodenart oder die Landschaft selbst; der landwirtschaftliche Organismus selbst. Es geht darum, in erster Linie diese Wesen zu verstehen und daraus abzuleiten, wie idealerweise mit ihnen umzugehen ist und in zweiter Linie, diese Ideale möglichst wirtschaftlich und möglichst machbar umzusetzen. Das... |

| 画像解析により算出された牛ロース芯面積に占める脂肪交雑の面積割合(脂肪面積比)と格付員によるBMSナンパーとの関連性におよぼす品種の効果を検討した。材料は黒毛和種32頭(以下，JB)，アパディン・アンガス種5頭(AA)，JB x ホルスタイン種7頭(BH)，JB x AA11頭(BA)およびJB x マリーグレー種3頭(BM)である. 粒子面積階層別に脂肪交雑粒子の平均面積とその標準偏差および粒子数を算出した. さらに脂肪交雑の配置バランスを数値化した. 同ーのBMSナンパーにおいて， JBの脂肪面積比は，他に比較し低い値を示した(Pく0.05). 粒子の平均面積は，すべての粒子面積階層においてJB，AAならびにBMが， BAおよびBHに比較し小さい傾向にあった. JBの脂肪交雑粒子数は，すべての粒子面積階層において少ない傾向にあった.また，JBおよびBMの脂肪交雑は，他の品種に比較し，均一に配置していた. Effecs of breed on the relationship between Beef Marbling Standard (BMS) number by the examiners and ratio of fat area to ribeye area (RFA) calculated by image analysis were investigated. Pictures of the ribeye area of 32 Japanese Black(JB)，5 Aberdeen Angus (AA)，7 JB x Holstein (BH)，11 JB x AA(BA) and 3 JB x Murray Grey (BM) were used. Averages and... |

| Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality and consumers' choice. The aim of this study was to determine allele and genotype frequencies of polymorphisms of the bovine genes, which encode leptin (LEP), thyroglobulin (TG) and diacylglycerol O-acyltransferase (DGAT1). A further objective was to establish the effects of these polymorphisms on meat characteristics. We genotyped 147 animals belonging to the Nelore (Bos indicus), Canchim (5/8 Bos taurus + 3/8 Bos indicus), Rubia Gallega X Nelore (1/2 Bos taurus + 1/2 Bos indicus), Brangus Three-way cross (9/16 Bos taurus + 7/16 Bos indicus) and Braunvieh Three-way cross (3/4 Bos taurus + 1/4 Bos indicus)... |

| The objectives of this study were to define breeding objectives and derive economic weights for production traits in family-based beef cattle systems, assess the sensitivity of these weights to changes in market and husbandry indicators and estimate the expected genetic changes in the selection criteria proposed. Based on data from the production systems, farms revenues and expenses, obtained from interviews and meetings with producers, a bioeconomic model was derived, relating biological traits of animals with the financial result of the production system based on calf-crop, selling male calves and culling cows for finishing. Traits considered in the model as breeding goals were weaning rate, weaning weight and cow weight. The economic weights, obtained... |
