Abstract
Cilj istraživanja je bio utvrditi proizvodnju i kvalitetu kozjeg mlijeka na ekološkom obiteljskom poljoprivrednom gospodarstvu. Istraživanje je provedeno na obiteljskom poljoprivrednom gospodarstvu na 17 koza u laktaciji, pasmine francuska alpina. Uzorci kozjeg mlijeka uzeti su tijekom jutarnje mužnje 30., 50., i 75. dana laktacije.Utvrđen jekemijski sastav mlijeka, odnosno sadržaj mliječne masti (%), bjelančevina (%), laktoze (%), suhe tvari bez masti, uree (mg/dl) i broj somatskih stanica (broj/ml). Podaci su pripremljeni u programu MS Excel, a dobiveni rezultati statistički su obrađeni u statističkom programu SAS® (9.4). Proizvedena količina jutarnjeg mlijeka iznosila je 1,47 kg 50. dana laktacije te 1,32 kg 75. dana laktacije, pri čemu nije bilo značajnih razlika. U istraživanju je vidljiva visoka varijacija sadržaja mliječne masti, koncentracije uree kao i broja somatskih stanica. Utvrđena je porast sadržaja bjelančevina 75. dana (3,11 %) u odnosu na 30. dan laktacije (2,77 %). Sadržaj laktoze je značajno smanjen 75. dana u odnosu na 50. dan laktacije. Koncentracije uree je značajno porasla 50. dana (37,3 mg/dl) u odnosu na 30. dan (25,8 mg/dl) laktacije. Kemijski sastav mlijeka povoljniji je s odmicanjem laktacije, osobito u sadržaju bjelančevina koje su vrlo važne za proizvodnju sira na ekološkom obiteljskom poljoprivrednom gospodarstvu.
Abstract (english)
The aim of the present study was to determine the production and quality of goat milk on organic family farm. The research was conducted on a family farm with 17 lactating goats of the French Alpine breed. Goat milk samples were taken during morning milking on the 30th, 50th, and 75th day of lactation. The chemical composition of milk was determined: content of milk fat (%), protein (%), lactose (%), dry matter without fat, urea (mg/dl) and the number of somatic cells (number/ml). The data were prepared in MS Excel, and the obtained results were statistically processed in the statistical program SAS® (9.4). The morning milk yield was 1.47 kg on the 50th day of lactation and 1.32 kg on the 75th day of lactation, although without any significant differences. The study resulted in high variations in milk fat content, urea concentration and somatic cells count. An increase in protein content was found on day 75 (3.11 %) compared to day 30 of lactation (2.77 %). Lactose content was significantly lowered on day 75 compared to day 50 of lactation. Urea concentration increased significantly on day 50 (37.3 mg/dl) compared to day 30 (25.8 mg/dl) during lactation. The chemical composition of milk is more favorable with the lactationprogress, especially in the content of proteins which are very important for cheese production on an organic family farm.
