Inluence of source and level of glycerin in the diet on growth performance, liver characteristics, and nturient digestibility in broilers from hatching to 21 days of age

The influence of source and level of inclusion of raw glycerin (GLYC) in the diet on growth performance, digestive traits, total tract apparent retention (TTAR), and apparent ileal digestibility of nutrients was studied in broilers from 1 to 21 d of age. There was a control diet based on corn and soybean meal and 8 additional diets that formed a 2 × 4 factorial with 2 sources of GLYC and 4 levels of inclusion (2.5, 5.0, 7.5, and 10%). The GLYC used were obtained from the same original batch of soy oil that was dried under different processing conditions and contained 87.5 or 81.6% glycerol, respectively. Type of processing of the GLYC did not affect any of the variables studied except DM and organic matter retention (P < 0.05) that was higher for the 87.5% glycerol diet. From d 1 to 21, feed conversion ratio (FCR) improved linearly (L, P ≤ 0.01) as the GLYC content of the diet increased, but ADG was not affected. On d 21, the relative weight (% BW) of the liver and the digestive tract increased (L, P < 0.01) as the level of GLYC in the diet increased, but lipid concentration in the liver was not affected. The TTAR of DM and organic matter increased quadratically (Q, P < 0.05) and the AMEn content of the diet increased linearly (L, P < 0.01) with increases in dietary GLYC. Also, the apparent ileal digestibility of DM (L, P < 0.05; Q, P = 0.07) and gross energy (L, P < 0.01) increased as the GLYC content of the diet increased. It is concluded that raw GLYC from the biodiesel industry can be used efficiently, up to 10% of the diet, as a source of energy for broilers from 1 to 21 d of age and that the energy content of well-processed raw GLYC depends primarily on its glycerol content.

Purification, cDNA cloning, functional expression, and characterization of a 26-kDa endogenous mammalian carboxypeptidase inhibitor.

The recent demonstration of the occurrence in rat brain and other nonpancreatic tissues of carboxypeptidase A (CPA) gene transcripts without associated catalytic activity could be ascribed to the presence of a soluble endogenous protein inhibitor. This tissue carboxypeptidase inhibitor (TCI), detected by the inhibition of added bovine pancreatic CPA, was purified from rat brain. Peptides were obtained by partial proteolysis of purified TCI, a protein of approximately 30 kDa, and starting from their sequences, a full-length cDNA encoding a 223-amino acid protein containing three potential phosphorylation sites was cloned from a cDNA library. Its identity with TCI was shown by expression in Escherichia coli of a recombinant protein recognized by antibodies raised against native TCI and display characteristic CPA-inhibiting activity. TCI appears as a hardly reversible, non-competitive, and potent inhibitor of CPA1 and CPA2 (Ki approximately 3 nM) and mast-cell CPA (Ki = 16 nM) and inactive on various other proteases. This pattern of selectivity might be attributable to a limited homology of a 11-amino acid sequence with sequences within the activation segments of CPA and CPB known to interact with residues within their active sites. The widespread expression of TCI in a number of tissues (e.g., brain, lung, or digestive tract) and its apparently cytosolic localization point to a rather general functional role, e.g., in the control of cytosolic protein degradation.
