Based on low 18:0 contents observed in milk fat of cows fed cactus cladodes (CC), we hypothesized that including Opuntia stricta cladodes in a soybean oil (SO)-supplemented diet would promote incomplete rumen biohydrogenation of supple-mental PUFA, leading to increased trans-11 18:1 and cis-9, trans-11 CLA contents in milk. Twelve Holstein cows were used in a two-period study: (a) Baseline: all cows received a total mixed ration (TMR) composed of sorghum silage (SS) and a concen-trate containing no SO for 14 days; (b) Treatment: cows received one of the follow-ing SO-supplemented diets for 21 days: (1) SS-TMR: a TMR composed of SS and a SO-enriched concentrate, (2) CC-TMR: a TMR containing CC as a partial substitute for SS plus the SO-enriched concentrate, and (3) CC-PMR: same diet as in treatment 2, but CC were mixed with the SO-enriched concentrate and fed as a partial mixed ration (PMR). Both CC diets increased relative abundances of trans-11 18:1, cis-9, trans-11 CLA, and 18:2 n-6 in milk fat, whereas opposite effects were observed on 18:0 and cis-9 18:1. Proportion of 18:2 n-6 increased, and cis-9, trans-11 CLA tended to increase with CC-PMR as compared to CC-TMR, whereas 18:3 n-3 was higher with CC-PMR than with SS-TMR. Proportions of several odd- and branched-chain fatty acids, certain 18:1 isomers, and trans-9, cis-11 CLA changed with CC diets, nota-bly with CC-PMR. Milk yield and intake of most nutrients (except fibre) increased or tended to increase with the CC diets, whereas gross milk composition was unaltered. Stearoyl-CoA desaturase-1 index for C18 (SCD18) was higher with CC-PMR than with SS-TMR, and milk n-6:n-3 FA ratio and apparent transfer of 18:2 n-6 to milk increased with CC diets. These results indicate that Opuntia stricta cladodes can be a valuable feed ingredient for improving the nutraceutical value of milk fat.

Synthetic or artificial seeds via encapsulated propagules could be used for in vitro regeneration and mass multiplication, for germplasm preservation and exchange of plant materials. An in vitro encapsulation of potato ?BRS Clara? buds efficient protocol was established. Lateral buds were immersed in a 4% sodium alginate matrix, dripped in CaCl2 for 20 minutes in different osmoregulatory agents: sucrose (8.72, 15.00, 21.28 and 30.00 g L-1) and mannitol (0.00, 11.63, 20.0, 28.37 and 40.0 g L-1). They were then held for 30 days at approximately 4°C and subsequently immersed in KNO3 for capsule decomplexing. Afterward, they were inoculated in MS medium with 3% sucrose and cultured in a growth room under irradiance of 43 μmol m-2 s-1, 16 hours-photoperiod and 25±2 °C temperature. Sucrose and mannitol at concentrations of 15 g L-1 and 20 g L-1, respectively, associated with the encapsulation matrix promoted 80% survival rate of ?BRS Clara? encapsulated buds. |
