Resposta de vacas leiteiras à substituição total de milho por polpa cítrica e à suplementação com microminerais orgânicos I: consumo e digestão

Arquivo Brasileiro de Medicina Veterinária e Zootecnia (2008)

Sandro César Salvador Marcos Neves Pereira Junio Fabiano dos Santos L.Q. Melo M.L. Chaves

Avaliou-se a resposta de vacas leiteiras à substituição total de milho maduro finamente moído por polpa cítrica peletizada. O teor dietético do milho foi 10% e o de polpa 24% nos tratamentos com milho, e o de polpa foi 33% nas dietas exclusivas com polpa. Simultaneamente, foi avaliada a substituição total de fontes inorgânicas de Cu, Mn, Se, Zn e Cr por fontes orgânicas. Quatro dietas baseadas em silagem de milho foram geradas por arranjo fatorial dos dois fatores. Dezesseis vacas receberam os tratamentos em quadrado latino 4x4. O efeito da substituição de fontes inorgânicas por fontes orgânicas de microminerais não foi conclusivo. O consumo diário de matéria seca foi 19,4kg na polpa e 20,5kg na dieta com milho (P=0,03). O consumo de matéria orgânica digestível foi maior nas dietas com milho (P<0,01). Houve tendência de queda na taxa fracional de degradação ruminal in situ da MS da silagem de milho (P=0,11) e de aumento no tamanho da fração indigestível (P=0,15) nas dietas com milho, sugerindo que a degradação de forragens não determinou o menor consumo nas dietas com polpa. A substituição total de milho por polpa cítrica pode reduzir o consumo e a digestibilidade.

Resposta de vacas leiteiras à substituição total de milho por polpa cítrica e à suplementação com microminerais orgânicos II: desempenho e economia

Arquivo Brasileiro de Medicina Veterinária e Zootecnia (2008)

Sandro César Salvador Marcos Neves Pereira Junio Fabiano dos Santos L.Q. Melo M.L. Chaves

Avaliaram-se o desempenho e a eficiência financeira de vacas leiteiras alimentadas com dietas com substituição total de milho por polpa cítrica. O teor dietético do milho foi 10% e o de polpa 24% nos tratamentos com milho, e o de polpa foi 33% nas dietas exclusivas com polpa. A substituição total das fontes inorgânicas Cu, Mn, Se, Zn e Cr por fontes orgânicas foi avaliada simultaneamente. As quatro dietas geradas por arranjo fatorial dos dois fatores foram fornecidas a 16 vacas em Quadrado Latino 4x4. As produções de leite foram 27,5kg para vacas alimentadas com polpa e 28,4kg para aquelas que receberam milho (P=0,04). A substituição total de milho por polpa cítrica reduziu o teor e a produção de proteína no leite (P<0,03), e não afetou a secreção de gordura (P>0,24). Dietas formuladas exclusivamente com polpa cítrica podem ser indicadas quando o pagamento do leite for baseado apenas no volume. A inclusão de milho pode aumentar a renda bruta subtraída do custo alimentar quando a produção de sólidos for valorizada.

1241 Accuracy and precision of diets for high-producing dairy cows and their impacts on production and milk composition

Journal of Animal Science (2016)

Jorge Henrique Carneiro Junio Fabiano dos Santos Patrick Schmidt T.J. DeVries Rodrigo de Almeida

The goal of this study was evaluate associated feeding management and nutritional accuracy with milk production and composition on commercial herds. Twenty high-producing dairy farms from Campos Gerais county, Paraná State, Southern Brazil, were visited for 3 consecutive days in the 2015 fall season. Feeding management and TMR preparation related variables, and the physical and chemical characteristics of the offered diets and orts were collected. Production performance and milk composition from the high-production group of cows were obtained from regular milk testing, performed on average 1 ± 5d before or after the data collection period. Pearson correlations were estimated among the management and diet variables with production, milk composition, and feed sorting estimates. Using the Penn State Particle Separator, the offered diets had on average 14.9, 41.8, 32.8, and 10.5% (DM) of long, medium, short, and fine particles, respectively. Long particles showed a daily refusal rate of 9.0%, whereas short and medium particles were preferentially consumed at 1.1 and 1.7%, respectively. A high proportion of long particles in the forage (78.2% of haylage and hay) was associated with reduction in milk fat % (%MF) (r = −0.50; P < 0.05), and an increased proportion of cows with fat:protein ratio lower than 1 (FPR < 1) (r = 0.50; P < 0.05). Errors associated with loading an excess of concentrate ingredients in the TMR wagon were negatively associated with %MF (r = −0.52; P = 0.05) and milk production (r = −0.47; P < 0.05). By comparing the formulated diet with the one delivered to the cows, we noted, on a DM basis, a decrease in CP (−3.1%), fat (−7.0%), and ash contents (−10.5%), and an increase in NDF (+10.3%). The accuracy observed between formulated and delivered diets was not associated with the performance of the cows. However, daily variation of the DM content of the diet was associated with a greater proportion of cows with FPR < 1, and reduced FPR (r = 0.40; P = 0.09 and r = −0.43; P = 0.07, respectively). Low homogeneity (across 3 d) of the % of long particles in the diet was associated with greater selection against these particles (r = −0.64; P < 0.05), which showed a curvilinear association with %MF. These results demonstrated that the addition of more concentrate ingredients than expected, as well as the inconsistent intake of different particle sizes throughout the day, had a negative impact on milk production and composition of the studied herds.

Accuracy and physical characteristics of total mixed rations and feeding sorting behavior in dairy herds of Castro, Paraná

Figshare (2022)

Jorge Henrique Carneiro Junio Fabiano dos Santos Rodrigo de Almeida

ABSTRACT The objective of this study was to assess the accuracy of the content of total mixed rations (TMR) offered to high-producing cows from 20 dairy herds of Castro, Paraná State, Brazil. The average milk yield during the sample collection period was 38.0±6.8 kg/day, with 3.47±0.25% milk fat and 3.05±0.18% milk protein. The particle size distribution of samples of fresh diet and leftovers was evaluated using the Penn State Particle Separator (PSPS) and chemical analysis was also conducted. The TMR homogeneity was estimated by the coefficient of variation (CV) of particles retained on the two intermediary sieves (<19 and >1.18 mm), in which a CV higher than 5% indicated a poorly mixed TMR. The TMR offered exceeded the formulated TMR only for NDF (+7.3%) and was lower than the formulated TMR for CP (−6.5%), ADF (−10.1%), and ash (−18.6%) contents. These differences are due to daily variations in feed quality, mixing equipment, and ingredient mixing order, mostly for forage. Differences between leftovers and TMR offered were substantial: −9.4% for CP, +25.1% for NDF, +31.6% for ADF, and +13.1% for ash, suggesting a feed sorting effect against long forage particles and in favor of small concentrate particles. The proportion of the offered TMR retained in the top PSPS sieve showed positive correlations with NDF (r = 0.58) and ADF (r = 0.54) contents of the refusals, which indicates that cows sort against long particles. Positive correlations were also found between the CV in the second sieve and NDF (r = 0.56) and ADF (r = 0.47) contents of refusals, suggesting that poorly mixed diets are more easily sorted by cows. Therefore, evaluating the chemical and physical properties of TMR, especially for forage, is extremely important for providing a consistent diet.

Intensive dairy farming systems from Holland and Brazil: SWOT analyse comparison

Figshare (2022)

Rodrigo Augusto Cortêz Passetti Carlos Emanuel Eiras Ludmila Couto Gomes Junio Fabiano dos Santos Ivanor Nunes do Prado

ABSTRACT. Intensive systems of milk production in Brazil and Holland are compared by SWOT analysis. Twenty-one farms, 10 in Wageningen, central region of Holland, and 11 in Castro, central-eastern region of the state of Paraná, Brazil, were sampled. Data were retrieved from semi-structured interviews with the owners or people responsible for dairy activities, using a questionnaire guide and a digital recorder. After results were analysed, a table was elaborated representing the strengths, weaknesses, opportunities and risks for each country. Dairy farms in Holland were uniform, or rather, small and medium-sized farms with high production. It has also been observed that Dutch farms have several problems due to high intensification, for example, hoof diseases with great economic loss. In the case of Brazilian dairy farms, several types of systems and degrees were detected. Brazilian production in the region analysed features a higher quantity than that in Holland, with less intensity when compared to that on Dutch farms.

Silagem de grãos úmidos de milho de textura dura ou macia em dietas com polpa cítrica para vacas em lactação

Arquivo Brasileiro de Medicina Veterinária e Zootecnia (2014)

F.M.J. Costa G.S. Dias Júnior O.F. Zacaroni Junio Fabiano dos Santos R.A.N. Pereira

Avaliou-se o desempenho de vacas leiteiras que consumiram polpa cítrica e dois teores dietéticos de silagem de grão úmido de milho. Os tratamentos foram: milho de textura dura ou milho de textura macia ensilado na linha negra, em fatorial com 9% ou 18% de milho na dieta. O teor de polpa cítrica na dieta foi de 16,2% ou 25,6%, com alto e baixo milho, respectivamente. Doze vacas receberam os tratamentos em quadrados latinos 4x4. A produção diária de leite foi 27,9kg no milho duro e 28,8 no macio (P=0,19). Alto milho diminuiu o teor de gordura do leite de 3,38 para 3,26% (P=0,04) e aumentou o teor de proteína de 2,99 para 3,03% (P=0,05) e a eficiência alimentar de 1,50 para 1,57kg de leite/kg de consumo (P=0,03). Aumento no teor de milho induziu maior queda no pH ruminal na dieta com milho macio do que na dieta com milho duro (P=0,05 para a interação textura versus teor de milho). O milho macio aumentou o consumo diário de matéria orgânica digestível de 11,7 para 12,3kg (P=0,05). Os parâmetros digestivos sugerem que a ensilagem não eliminou totalmente o efeito da textura do endosperma sobre a digestibilidade do milho.
