Pseudohypoparathyroidism: Challenges in Early Recognition and Diagnosis of a Rare Hereditary Disorder.

Pseudohypoparathyroidism (PHP) is an uncommon endocrine condition marked by an impaired response to parathyroid hormone (PTH), which results in biochemical abnormalities. Clinical manifestations can vary significantly, occasionally resembling other endocrine disorders. Genetic testing plays a critical role in distinguishing PHP from other conditions, as it enables precise diagnosis even when classical features are not initially present.

Energy metabolism of pregnant zebu and crossbred zebu dairy cattle.

The purpose of this study was to determine the energy partition of pregnant F1 Holstein x Gyr with average initial body weight (BW) of 515.6 kg and Gyr cows with average initial BW of 435.1 kg at 180, 210 and 240 days of gestation, obtained using respirometry.

Energy partitioning in cattle fed diets based on tropical forage with the inclusion of antibiotic additives.

The aim of this study was to describe energy partitioning in dairy crossbreed bulls fed tropical forage-based diets supplemented with different additives. Twenty F1 crossbred bulls (Holstein x Gyr) with initial and final live weight (LW) averages of 190 ± 17 and 275 ± 20 kg were fed sorghum (Sorghum bicolour) and Tanzania grass (Panicum maximum cv. Tanzania) silage (70:30 DM basis) with supplemented concentrate at a forage to concentrate ratio of 50:50.
