| 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... |

| The aim was to evaluate the feeding behavior, carcass characteristics and meat quality of Nelore heifers fed sunflower pie replacing cottonseed meal. They were used 30 heifers with average initial weight of 274 kg ± 28 kg and average age of 24 months, confined for 76 days. The design was completely randomized with five treatments (0, 150, 300, 450 and 600 g kg-1 DM) and six replicates per treatment. By completing 24 hours after slaughter, it evaluated muscle conformation and degree of finish made the longissimus dorsi at the 13th rib. A representative sample between the 10th and 12th ribs was collected for evaluation of the physical components of carcasses. As well as the other variables, the hot carcass weight, dressing percentage, carcass length and rib... |

| Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four slaughter-weight classes, namely <340, 340-370, 370-400, or >400 kg. Back fat thickness was not influenced (p > 0.05) by slaughter weight in any of the forms it was expressed (mm or %), averaging 5.3 mm. Loin eye area in cm2 increased (p < 0.05) with the increase in slaughter weight. Animals slaughtered at a live weight (LW) of more than 400 kg showed better (p < 0.05) carcass conformation than the other experimental groups (9.8 points). Heifers slaughtered at over 400 kg LW had a more compact (p... |

| The Brazil sacrifices many dairy calves at birth, which can become a very serious problem merchandising. The objective of this experiment was to evaluate the physical carcass composition and meat quality characteristics of Holstein calves in feedlot or pasture with supplementation, slaughtered at 140, 180, 220 or 260 kg body weight. In the early termination calves had on average 57 kg and 58 days of age. The confined animals were fed forage (corn) and concentrated, in the ratio of 40:60 and concentrated pasture supplemented with 1% body weight. The experimental design was completely randomized in a factorial 2 x 4 (two feeding systems x four slaughter weights). It was observed a significant interaction between slaughter weight and finishing system only for... |

| 黒毛和種ロース芯内における脂肪交雑の量，形状および分布均一性の月齢変化と，それに対する種雄牛の影響を調査するために，北海道内の枝肉市場に25～33ヵ月齢で出荷された黒毛和種4,130頭（去勢3,087頭，雌1,043頭）を用いた．第6-7胸椎切開面のロース芯画像を4領域に分割した．ロース芯全体と各領域について，脂肪面積割合，あらさ指数および細かさ指数を算出し，出荷月齢による推移を調査した．去勢において，脂肪面積割合の見かけ上のピークは一つの領域を除いて30ヵ月齢にあったが，31ヵ月齢以降において脂肪交雑の細かさが増大した．雌はすべての領域において脂肪面積割合の見かけ上のピークが30または32ヵ月齢にあり，脂肪交雑の細かさは去勢牛と異なり上昇しなかった．領域によって脂肪面積割合の月齢推移は異なり，去勢では25ヵ月齢で最も脂肪面積割合の低い領域が大きな増加を見せた．また，脂肪面積割合とBMSが見かけ上ピークになる出荷時期は，種雄牛によって異なっていた． |

| Several methods such as PCR-RFLP, OLA, DNA sequencing, PCR-SSCP and ARMS-PCR have been developed to detect the allelic variation at substitutions K232A of DGAT1, GH6.1 of GH, F279Y of GHR, R4C of LEP, I74V of FABP4, and at the transition in the TG 5´ leader sequence. Most of these methods are manual processes and therefore increase the time spent on the assay and limit the number of animals analyzed. Herein, we describe the development of pyrosequencing-based methods for the bovine DGAT1, GH, GHR, LEP, FABP4 and TG genes, whose polymorphisms have been associated with variation in carcass composition. This method was validated by analyzing DNA samples belonging to the Aberdeen Angus and Hereford breeds previously typed by PCR-SSCP, PCR-RFLP and/or DNA... |

| ABSTRACT: The present study aimed to evaluate the effects of immunocastration on the animal growth, carcass traits, and meat quality of Nellore cattle receiving or not Ionophore supplementation at pasture or pasture with concentrate (semi-feedlot). The first experiment (Pasture) was carried out during the rainy season, while the second (supplemented = Semi-feedlot) was conducted during the dry season. In each assessment, 60 males were allocated into three treatments, in a completely randomized design: non-castrated, immunocastrated (anti-gonadotropin-releasing hormone vaccine), and immunocastrated animals receiving ionophore. The highly energetic supplemented diet was prepared using 85 % corn and 10 % soybean meal at 1 % body weight, while the ionophore... |

| The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus... |

| Intramuscular fat (IMF) influences important quality characteristics of meat, such as flavor, juiciness, palatability, odor and tenderness. Thus, the objective of this study was to apply the following image processing techniques to quantify the IMF in beef: palette; sampling, interval of coordinates; black and white threshold; and discriminant function of colors. Thirty-five samples of beef, with a wide range of IMF, were used. Color images were taken of the meat samples from different muscles, with variability in the IMF content. The IMF of a thin cross-section meat was determined by chemical lipid extraction and was predicted by image analysis. The chemical method was compared with the image analysis. The segmentation procedures were validated by the... |

| In a study of beef quality, consumers tasted steak samples and participated in an experimental auction to determine their willingness to pay. Steaks differed in marbling, tenderness, country of origin, and aging method. Marbling and tenderness had statistically significant impacts on consumers' palatability ratings for steaks. Tenderness significantly impacted consumers' willingness-to pay values. There appear to be threshold levels of marbling and tenderness, below which consumers discount steaks. Steaks from Australia were rated lower for overall acceptability, and bids were lower than for the U.S. steak samples. Dry-aging methods negatively impacted taste panel ratings and bids. |

| 高解像度デジタルカメラを利用した新たな牛枝肉横断面撮影装置を開発すること，ならびに開発された新型撮影装置と従来型の撮影装置の双方を用い，黒毛和種の枝肉横断面を撮影し，両装置から得られた脂肪交雑の評価値の比較を実施することを目的とした。330mmの装置の高さから，広範囲の画像を撮像するために， 35mm版のCCD素子を有するデジタルカメラを選定した。また，正像が確保できるレンズとして，画角114度の超広角レンズを採用した。さらに，遮光された僅体内部には，高輝度LEDが密に並んで実装されているl次元CCDカメラ用のライン 方式照明を2燈取り付けた。新型撮影装置ならびに従来型撮影装置から得られる画像を比較するために，黒毛和種去勢牛20頭の枝肉横断面を，双方の撮影装置で撮影し，画像解析により，脂肪交雑の特徴量を算出し，両者の比較を実施した。超広角レンズを使用したことにより，撮像範囲は384mmX318mmと，従来型に比較し，約2倍の面積を1回で撮影することが可能となった。ロース芯面積ならびに脂肪面積比について，両撮影装置の聞での相違は，大きいものでそれぞれ2c㎡，3%程度であった。また，新型撮影装置で明確に確認できる脂肪交雑粒子の最小面積 は0.004㎡程度であった。 |
