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.

ABSTRACT. The circular saw is a tool commonly used for wood processing. It may be presented at different models. Considering their specificities, they can generate different amount of waste. The objective of this study was to evaluate the generation of waste from Tectona grandis L. f. and Pinus caribaea var. hondurensis, processed with two saws of the multiple type (48 and 36 teeth) and one of the universal type (28 teeth). The cutting process followed in grain direction into ninety samples, 15 for each species and saw, until the sample was completely processed. The processing time was measured and the waste was collected in each operation. ANOVA and test of multiple comparison of averages were applied. The influence of the teeth number and type of saw on the amount of waste generated was verified. The universal saw was the one that generated the highest amount of waste. It reached up to 116% more than the multiple saw, that generated the lowest amount of waste (36 teeth). P. caribaea var. hondurensis generated 7% more waste and presented shorter processing time (22%), when compared to T. grandis. TÍTULO.
