摘要
The goals of this study were to determine the weekly milk production of Saanen goats at UniSZA Pasir Akar Farm,and to evaluate milk production and composition in three age groups.From January 2021 to May 2021,a study was conducted at the UniSZA Pasir Akar Farm in Besut,Terengganu.Ninety goat milk samples were collected and stored in sterile falcon tubes.Milk samples were stored in an insulated box at 5℃ before being transported to the laboratory and stored at-20℃ until further analysis.Milk samples were analyzed in four replicates for each sample group using the Milkotester.The one-way analysis of variance(ANOVA)method was used to analyze raw data among age groups,with p<0.05 indicating a significant difference.The highest milk yield was produced by four-year-old goats(943.9 g/d),followed by three-year-old goats(850.5 g/d)and two-year-old goats(571.1 g/d),respectively.Solid non-fat(SNF),protein,and lactose content showed the highest in percentage in the 3-year old group,at 7.80%,2.80%,and 4.27%,respectively.However,the fat content revealed an unusual pattern,with 2.87%,2.77%,and 3.33%representing 2,3 and 4 years old.This occurred due to other factors such as feed,breed,and age.In conclusion,this study found a significant difference in milk yield and composition across three age groups.However,this is only a preliminary result based on a small number of animals and a short study period.Future studies will perhaps,use larger sample sizes and parameters to validate the current result.
