Milk Production Curve on Various Test Day Patterns (Case in BBPTU-HPT Baturraden)

Abstract

Information about milk production in dairy cows is obtained most accurately by daily recording, but with consideration, such as time and cost. This study aimed to obtain accurate and efficient recording patterns to estimate milk production in dairy cows. This research used recording of milk production in BBPTU-HPT Baturraden. The data used is the record of milk production of Test Day (TD) from the year 2014-2017 as many as 8696 records of TD that derived from 213 head of cows on first lactation. The record of TD milk production is the recording of milk production performed only on certain days during a lactation period. The milk production expectant curve used is the Ali-Schaeffer. The result of this research that Ali-Schaeffer equation with correlation between estimated and actual value (r) 0.991, standard error (se) 0.64, and standard deviation (stdv) 0,01. Recording of milk production Pattern 5, namely the recording of milk production in TD 1, 2, 5, 8, and 11, showed the highest correlation value (r=0.998). It is recommended to record the milk production in the early months of lactation and combined with the recording of TD milk production periodically every three months, from mid to late production.

Estandarización de la producción de leche mediante métodos alternativos al registro estándar en vacunos lecheros

“…Sin embargo, registrar la producción de leche de cada animal durante el periodo de lactancia puede ser difícil, incluso, si los productores realizan el registro, generalmente está incompleto(Naranchuluum et al, 2011;Gupta et al, 2016). Los registros incompletos dificultan predecir la producción de leche durante un período de lactancia(Indrijani et al, 2019).El registro lechero en el Perú tiene su inicio en el año en 1950 por la Universidad Nacional Agraria La Molina, el Ministerio de Agricultura y la Asociación de Ganaderos de la Cuenca de Lima, con la finalidad de evaluar la…”
