Abstract
The objective of the study was to compare through simulation Holstein and Jersey breed herds, considering the farm size, zootechnical and economic indexes and profitability of the activity, by using different systems of bonus payment for milk price based in percentage of fat and protein in the milk. The comparisons were made, initially, disregarding the bonus payment for milk price based on the increase in the fat and protein percentage in milk. After that, the profitability of the activity was compared considering bonus payment for milk price of the Jersey breed herd, for each unit increment in fat and protein percentage in milk above those obtained with the Holstein breed herd. Finally, the profitability of the activity was compared by using the bonus payment for milk price based on quality of that used by company A systems. When there was no bonus payment for milk price based in the percentage of fat and protein in the milk, the profit obtained with the Holstein breed was higher because of the lower production costs. In order to make the activity more profitable with the Jersey breed, a bonus payment of 5% for milk price would be needed for each percentage unit of fat above the percentage of that obtained with the Holstein breed, or a bonus payment of 10% in the milk price for each percentage unit of protein above the percentage obtained with the Holstein breed. By using the bonus payment system proposed by Gimenes and Ponchio, the annual profit with the Jersey breed was higher than the profit obtained with the Holstein breed. However, with the application of the bonus payment system used by company A, the Holstein breed became more profitable than the Jersey breed.
Objetivou-se com este estudo comparar, por meio de simulação, de rebanhos das raças Holandês e Jersey em um sistema de produção de leite em confinamento, considerando o tamanho do rebanho, os índices zootécnicos e econômicos e a lucratividade da empresa, mediante a utilização de um sistema de bonificação pela porcentagem de gordura e proteína do leite. As comparações foram realizadas primeiramente desconsiderando bonificações pela porcentagem de gordura e proteína do leite. Em seguida, a lucratividade foi comparada considerando bonificações no preço pago pelo leite da raça Jersey a cada unidade de acréscimo na porcentagem de gordura e de proteína do leite acima do obtido com a raça Holandesa. Por fim, a lucratividade foi comparada utilizando-se o sistema de bonificação de preço pago com base na qualidade e no preço adotado por uma empresa integrante do mercado de laticínios. Quando não há bonificação no preço pago pelo leite, o lucro obtido com a raça Holandesa é maior, em razão dos menores custos de produção. Para que a atividade com a raça Jersey seja mais lucrativa, é necessária bonificação de 5,0% no preço do leite para cada unidade porcentual de gordura do leite, ou bonificação de 10,0% no preço do leite para cada unidade percentual de proteína do leite, acima daquela obtida com a raça Holandesa. Com a utilização do sistema de bonificação com base na qualidade do leite, o lucro anual com a raça Jersey é maior que o obtido com a raça Holandesa. Entretanto, com a aplicação do sistema de bonificação utilizado pela empresa A, a raça Holandesa torna-se mais lucrativa.
