Milk Quality of Anglo Nubian X Etawah Grade Goats and Saanen X Etawah Grade Goats at First Kidding Period

Abstract

Goat milk has been well-known as useful human consumption due to its nutrition content and medical for many diseases. To improve productivity of dairy goats is through crossbreeding between local breed and adapted exotic breed. A study was carried out to evaluate milk quality of Anglo Nubian (AN) x Etawah grade (PE) goats and Saanen (SA) x Etawah Grade goats. There were 26 does rst kidding that consisted of 15 ANxPE does and 11 SAxPE does used in this study. All does were raised and given same feeding and management system at Dairy Goat Unit of Indonesian Research Institute for Animal production. A weekly single hand milking data was collected for milk quality from 12 weeks evaluated by lacto-scan. Data were analyzed using linear model from SAS program. Results indicated that there were signi cant difference (P<0.01) in fat and total solid milk content between the two genotypes, with overall means (%) for fat content 5.01 and 4.88, protein 3.02 and 2.98, lactose 4.94 and 4.97 and total solids 13.68 and 13.17 for ANxPE and SAxPE. The weeks of lactation affected fat and protein contents (P<0.01). It can be concluded that ANxPE does produced acceptably fat and protein content. This study might be used as early information used for recommendation in increasing goat milk production and quality.
