Milk production and lactation length of F2 Anglo Nubian Etawah grade does

Abstract

Goat milk has many benefits that resulted in increasing its consumption. A study was carried to evaluate total milk production and lactation length of F2 Anglo Nubian (AN) Etawah Grade (PE) crossbred does in different lactation numbers. There were thirty-eight does of F2 AN PE used in this study. All does were raised in IRIAP laboratory pens and the same feeding system and management. Daily single hand milking data were collected for total milk production per lactation of the first-third lactation between the year 2018-2019. The data were analyzed using a linear model from the SAS program including lactation numbers as a source of variation. Results had shown that lactation numbers significantly affected total milk production and lactation length (P<0.05). The first lactation of AN PE does perform the lowest milk production and lactation length while the thirds showed the highest. The milk production and lactation length increased as lactation numbers increasing. It can be concluded that total milk production and lactation length were affected by lactation numbers. This study might be used as a consideration in improving milk production of crossbred goats using AN goats.
