Dose-dependent effect of spent coffee grounds on intake, apparent digestibility, fermentation pattern, methane emissions, microbial protein supply, and antioxidant status in Latxa sheep.

Spent coffee grounds (SCG), a byproduct rich in polyphenols, can form part of enteric CH4 mitigation strategies while promoting the circular economy. This study aimed to evaluate the effect of 3 levels of SCG inclusion in the concentrate on enteric CH4 production, feed intake, apparent digestibility, ruminal fermentation pattern, microbial protein supply, and gene expression of immune and antioxidant markers in peripheral blood of dry dairy ewes. In a replicated 4 × 4 Latin square design, 8 nonproductive Latxa ewes were assigned to a concentrate that differed in the level of SCG: Control (0 g/kg DM), SCG100 (100 g/kg DM), SCG150 (150 g/kg DM) and SCG200 (200 g/kg DM).

[Long term results in treatment of residual hip dysplasia by Salter osteotomy (study of 31 cases)].

Thirty-five hips (31 children, operated between 1971 and 1982) were reviewed after skeletal maturity with a mean follow-up of 12 years. The 31 children had been treated initially by closed reduction of the hip using the Somerville-Petit method (mean age: 18 months), and subsequently by innominate osteotomy (mean age: 4 years) to correct a residual dysplasia which was graded upon the VCE angle, and Severin and McFarland's classifications. There were 88% good results; however only 51% of hips were classified Severin Ia and McFarland 1.
