Abstract
The study aimed to determine the effect of linseed use on lactating Ettawa crossbreed dairy goat rations in terms of protein quality had been carried out both in vitro and in vivo. In vitro experiments were carried out using rumen fluid as a source of inoculum from 5 Simmental cows. While in vivo experiments were carried out using 16 heads of lactating dairy crossbreed goat. Sixteen heads of goats were allotted according to completely randomized design. The goats were distributed into 4 treatments. The treatments consisted of basal ration consisted of 11.8% forage and 88.2% concentrate (T1), and ration consisted of 11.8% forage and 78.9% concentrate supplemented with 9.3% linseed (T2), 9.3% linseed protected with 10 g/kg formaldehyde (T3), or 9.3% linseed protected with 34 g/kg cinnamaldehyde (T4). All goats received Odot Grass and concentrate at the level of 5% of body weight. The results showed that the protection using both formaldehyde and cinemaldehyde had no significant differences (P <0.05). Ammonia concentration is not affected by the treatment of protected linseed use. Microbial proteins analyzed by the Lowry method gave different results not significantly. This shows that the four treatments were able to provide nutrients for rumen microbial. Protein digestibility of rations and protein contained in milk from the four treatments showed that it did not differ between treatments. It is concluded that rations containing protected or unprotected linseed have no effect on ammonia concentration, protein micobial in rumen fluid, protein digestibility and milk protein.The study aimed to determine the effect of linseed use on lactating Ettawa crossbreed dairy goat rations in terms of protein quality had been carried out both in vitro and in vivo. In vitro experiments were carried out using rumen fluid as a source of inoculum from 5 Simmental cows. While in vivo experiments were carried out using 16 heads of lactating dairy crossbreed goat.
