The objective of the study was to assess the effects of substitution milk and egg for soya products in breeding diets for rats, with concomitant decrease of the dietary protein level and supplementation with amino acids. Soya-containing (S) and two soya-free (NS and NSA) diets were evaluated as protein and energy sources, and their effects on reproductive(More)
The effects of indigestible carbohydrates, protein type, and protein level on large intestine health were examined in rats. For 21 days, 12 groups of six 12-week-old male Wistar rats were fed diets with casein (CAS), or potato protein concentrate (PPC), providing 14% (lower protein level; LP), or 20% (higher protein level; HP) protein, and containing(More)
In 2 two-factorial experiments, each conducted on 80 growing male rats, the effects of substituting 10% raw potato starch (PS), pectins (PEC), or cellulose (CEL) for wheat starch (WS) and the addition of tannic acid to WS (WSTA) were studied using diets differing in protein quality. Casein unsupplemented or supplemented with DL-methionine and gluten(More)
The effects of feeding varied levels of low- and high-gramine yellow lupin seeds (LG and HG, respectively), and of synthetic gramine added to the diets in amounts ranging from 0.15 to 1.2 g per kg were investigated in one experiment on growing chicken and in two experiments on growing rats. The comparison of LG and HG lupin and the effect of 0.5 g gramine(More)
Nutritional value of diets containing 10% potato fibre or cellulose (diets MPF and MC, respectively) and their long-term effects on parameters related to potential health benefits were studied in rats. In a first experiment nutrient digestibility and metabolisable energy of the diets were determined. In a second experiment, each diet was fed to 20 male and(More)
Forty-eight gilts were submitted to a 30% restriction of feed (groups F and F1) or protein intake (group P) from 90 to 118 days of age, followed by realimentation from 119 to 168 days of age. Control pigs (C) were fed during the whole experiment according to a semi ad libitum scale. During realimentation all animals were fed according to semi ad libitum(More)
In a two-factorial experiment on 96 young male rats, the effects of substituting 10% raw potato starch (PS), pectins (PEC), or cellulose (CEL) for corn starch (CS) were studied using an unsupplemented protein-free (PF) diet or a PF diet supplemented either with DL-methionine or urea. The pH and the short chain fatty acids (SCFA) content in caecal digesta,(More)
Pancreatic secretion in rats was assessed by measuring the amounts of p-aminobenzoic acid (PABH) excreted in urine after oral administration of Ac-L-Tyr-PAB, and by determination of enzyme activity in pancreas and faeces. 3 groups of 7 rats were kept on diets with casein as the main source of nitrogen without (control K0) or with two levels of trypsin(More)
The composition and nutritional value of 00-type industrial rapeseed meals containing lecithin gums either precipitated with citric acid (meal ALAC) or removed from oil by hydration (meal BLH) were determined. Control meals without lecithin (A and B) were included in the study. The ether extract content was over 20 g/kg greater, while the protein content(More)
