“…On the other hand, PRO and CON animals had an almost constant deposition of BFT, but it was greater for PRO animals, for the reasons discussed above. Another possible explanation for the BFT results of animals fed PRO is the additional protein supply associated with greater DMD during the third period, which may have resulted in greater ruminal organic acid production, including precursors for fat synthesis [44,45]. There was a treatment x period interaction for LD, which happened in the second and third periods (Fig 4).…”

The literature lacks studies investigating the performance of supplemented replacement heifers grazing on intensively managed warm-season pasture. Our objective was to evaluate the effects of supplement composition (energetic or protein) on the performance, muscle development, thermogenisis, nutrient intake, and digestibility of replacement Holstein heifers grazing Mombaça grass. Eighteen Holstein heifers with an average age and initial body weight (BW) of 12.57 ± 2.54 mo and 218.76 ±47.6 kg, respectively, were submitted to a randomized block design, with six replicates on a rotational grazing system of Panicum maximum cv. Mombaça pasture. Treatments were: control (CON; mineral salt ad libitum); energy supplement (ENE; corn meal as supplement, 8% CP and 3.78 Mcal/kg DE); and protein supplement (PRO; corn and soybean meal, 25% CP and 3.66 Mcal/kg DE). Supplements were individually fed at 0.5% BW. The experiment lasted 120 days, subdivided into three periods. Titanium dioxide and indigestible neutral detergent fiber (iNDF) were used to estimate the intakes and digestibility of the nutrients. BW, wither height, thoracic circumference, body length, and ultrasound of ribeye fat thickness measurements were taken once per period. Body condition score (BCS) was assessed twice during the experiment. The MIXED procedure of SAS, including period as a repeated measure, was used and significance was declared at P ≤ 0.05. Dry matter intake (DMI), CP intake (CPI) and DE intake were greater in heifers fed PRO compared to CON and ENE. Heifers supplemented with ENE had the lowest DMI. Treatment affected pasture intake/BW; it was similar between PRO and CON heifers, and lower for the ENE treatment. A treatment × period interaction was observed for NDF intake (%BW), in which heifers fed PRO and CON had the greatest NDF intake and ENE had the lowest. The digestibility of DM was the greatest in PRO-supplemented heifers and the lowest in CON heifers. Heifers fed ENE had decreased CP digestibility compared to PRO and CON heifers. Average daily gain (ADG) and thoracic circumference gain were greatest in the PRO treatment. BCS was greater in PRO compared to CON and ENE heifers. Supplementing Holstein heifers at 0.5% BW using PRO supplementation resulted in better animal performance, primarily greater ADG, than feeding ENE or not supplementing (CON). In conclusion, our results indicate that dairy heifers should be fed a protein supplement when grazing intensively managed Mombaça grass pasture.

“…Porém, se for considerado que boa parte das fêmeas é abatida como descarte de rebanhos reprodutivos, o número mais representativo é a desclassificação dos machos, uma vez que 15,7% dos novilhos estão velhos para a certificação da carne. Esses resultados indicam a existência de sistemas de produção com baixo ganho de peso, que não conferem acabamento aos novilhos ainda jovens (12,13) .…”

The objective of this work was to analyze price aggregation and disaggregation in commercialized animals searching for "Programa Carne Angus" benefits in the state of Rio Grande do Sul, Brazil. Data from 40,698 carcasses with Angus cattle racial pattern, slaughtered in a meat industry that performs the "Programa Carne Angus "certification, during the 2014 year were analyzed. The aggregated value was calculated by the difference between the negotiated base price for the lot and the final price obtained by animal after the certification process. The disaggregation was calculated based on the factors preventing the animals from being included in the certification program. The results show that the major disqualifying factor in males with the racial pattern was carcass fatness, and for females was the dentition, which disqualified 34.3 and 12.7% respectively. Value breakdown from 7,177 disqualified animals due to lack of finishing, or advanced dentition, reached R$ 1,213,528.00, or US$ 369,077.86 (US$ 51.43 per head), an amount that is no paid on from the industry to rural producers.Keywords: Aberdeen Angus, beef cattle dentition, beef cattle meat chain, fatness carcass, quality meat.

“…Embora os valores de pH de todos os tratamentos tenham ficado muito próximos entre si e da faixa esperada para uma fermentação de qualidade (entre 3,8 a 4,2), verificam-se diferenças significativas entre as médias, sendo que os melhores valores foram observados no T3 (4,15) e os maiores valores no T2 e T4 (4,32 e 4,23, respectivamente) (Tabela 3). Igarasi et al (2008) obtiveram resultados semelhantes, 4,50 a 4,68 pH para tratamentos utilizando a umidade em torno de 35%, levando em consideração que o pH para silagens de grão úmidos reconstituídos pode ser maior do que as silagens de grãos convencionais (LOPES et al, 2005).…”

RESUMO: A técnica da ensilagem de grãos reumedecidos consiste em devolver ao milho seco a umidade recomendada para que possa ser acondicionado em silos e submetido a processo de fermentação anaeróbica. Entretanto, a reconstituição da umidade do milho que já foi seco pressupõe menor perfil microbiológico e nutricional desse produto. Assim, esta pesquisa objetivou avaliar os efeitos de diferentes sistemas de secagem de milho sobre a qualidade da silagem oriunda de grãos reidratados, bem como, sobre o desempenho de leitões em fase de creche. Os grãos de milho foram colhidos com diferentes teores de umidade e submetidos a diferentes processamentos: naturalmente ensilados, sem a secagem e reumedecimento dos grãos (testemunha) e ensilados após reumedecimento dos grãos secos por diferentes métodos de secagem. Para avaliação da qualidade, foram realizadas análises de pH das silagens e condutividade elétrica dos grãos. O ensaio de desempenho de leitões em fase de creche foi conduzido num delineamento em blocos ao acaso, com quatro tratamentos, cinco repetições. Os resultados indicaram maior efeito deletério para o milho seco em alta temperatura. O ensaio de desempenho animal detectou diferenças entre os tratamentos, em favor da secagem artificial dos grãos, apenas até aos 18 dias de idade dos leitões.

MOIST CORN GRAIN SILAGE, RECONSTITUTED FROM DRY GRAIN IN DIFFERENT DRYING SYSTEMS, FOR PIGLETS FEEDING ABSTRACT: The technique of ensiling re-moistened grains consists of returning the recommended moisture to the dry corn so that it can be placed in silos and subjected to an anaerobic fermentation process. However, the reconstitution of moisture in corn that has already been dried presupposes a lower microbiological and nutritional profile of this product. Thus, this research aimed to evaluate the effects of different corn drying systems on the quality of silage from rehydrated grains, as well as on the performance of piglets in the nursery phase. The corn grains were harvested with different moisture contents and submitted to different processing: naturally ensiled, without drying and rewetting the grains (control) and ensiled after rewetting the dried grains by different drying methods. To evaluate the quality, analyzes of pH of the silages and electrical conductivity of the grains were carried out. The performance test of piglets in the nursery phase was carried out in a randomized block design, with four treatments, five replications. The results indicated a greater deleterious effect for corn dried at high temperature. The animal performance test detected differences between treatments, in favor of artificial drying of grains, only up to 18 days of age of piglets. Keywords: Rehydrated, performance, silage.
