Taurine (Tau) deficiencies have been associated with the feeding of commercial lamb-meal and rice diets to dogs. We hypothesized that the poor digestibility of some lamb-meals may limit sulphur amino acids availability for Tau synthesis and/or increase of Tau degradation in the gut. Growing dogs were fed either a lamb-meal-based (Diet A) or poultry by-product-based (Diet B) commercial diet. Pla...

Fermented mixtures containing fish-offal meal (FOM) and mulberry leaf meal (MLM) were used as protein supplement to partially replace fish meal (FM) in the formulation of diets for the Indian minor carp Labeo bata. The diets included a reference diet (20 % FM), three diets of fermented mixture of FOM and MLM (T2–T4) replacing 50 to 75 % of FM. Formulation of diet with 30 % FOM, 24 % MLM and 5 ...

The effect of diet on the occurrence of canine atopic dermatitis (CAD) in the high-risk breeds boxer, English bull terrier and West Highland white terrier was investigated as part of an extensive case-control study. In that study, a sparing association was seen for feeding the bitch a diet containing non-commercial ingredients during lactation and the subsequent development of CAD in the offspr...

A dog's nutrient requirements can theoretically be met from a properly balanced meat-free diet; however, proof for this is lacking. Exercise places additional demands on the body, and dogs fed a meat-free diet may be at increased risk of developing sports anaemia. We hypothesised that exercising dogs would remain in good health and not develop anaemia when fed a nutritionally balanced meat-free...

Life histories of "wild" house dust mites, Dermatophagoides pteronyssinus (Trouessart) (Acari: Pyroglyphidae), were compared with laboratory cultures by using a diet consisting of skin and dust or a laboratory diet consisting of dried liver and yeast. Under constant conditions of 25 degrees C and 75% RH, fecundity and rate of reproduction were higher in laboratory cultures on both diets compare...

background and objectives evaluation of protein quality in food is of great importance due to the biological and economical impacts of food proteins. this study has been conducted with the aim of comparing the protein quality of homemade food (mixture of macaroni and soy bean) with commercial baby food (cerelac wheat) using casein as the refference point.   methods this study was conducted on 6...

To evaluate the influence of mass of ruminal contents on voluntary intake and ruminal function, five ruminally cannulated steers (550 kg) were fed an orchard grass hay diet ad libitum in a 5 x 5 Latin square experiment. The mass of ruminal contents was altered by adding varying weights of modified tennis balls to the rumen before the initiation of each 15-d experimental period. Treatments consi...

Abstract The effect of four diets on the performance Dorper lambs that were artificially mix-infected with 1000 infective larvae (L3) Haemonchus contortus and L3 Trichostrongylus colubriformis every three days for 12 weeks was evaluated. For each diet, one infected group (n = 7) control 4) set up. contained following proportions hay (H) concentrate (C): Diet 1 - 100%H; 2 75%H:25%C; 3 50%H:50%C;...

Two experiments were conducted to study the effect of phytase supplementation to lowphosphorus starter and finisher broiler diets on mineral utilization and growth performance. All diets in this study were isonitrogenous, isocaloric and corn-soybean diets. In Experiment 1, four replicate groups of 15 commercial broiler chicks, one-day old, were randomly assigned to each of two dietary treatment...

Three experiments were conducted to determine the effects of pelleting and extrusion of feeds on the utilization of phytate P by broilers. The first experiment investigated the effects of pelleting the whole corn-soybean meal (SBM) diet, the corn, or SBM separately on phytate P utilization. The P-deficient basal diet contained 0.5% total P and 0.2% phytate P. Steam pelleting the whole diet, the...
