In order to estimate the crude protein (CP) equivalence value of Natuzyme-p (NP) enzyme by using regression response equations, two experiments were carried out using Ross (308) broiler chicks. Graded levels of dietary CP (while amino acids levels were kept constant) and NP enzyme were used to derive the regression equation in the first experiment. Four levels of dietary CP and NP enzyme were f...

The present study evaluated growing mink (Neovison vison) as a model for dietary protein quality assessment of protein meals used in extruded dog foods. Three foods with similar CP content but of different protein quality were produced using different protein meals. The protein meals varied with respect to CP digestibility and AA composition and included lamb meal (LBM), poultry meal (PM), and ...

The objective of this study was to determine if a moderate or high reduction of dietary CP, supplemented with indispensable amino acids (IAA), would affect growth, intestinal morphology and immunological parameters of pigs. A total of 40 barrows (initial BW=13.50±0.50 kg, 45±2 day of age) were used in a completely randomized block design, and allocated to four dietary treatments containing CP l...

An experiment was conducted to measure the effect of thermal treatment on the digestibility of CP, AA, starch, NDF, ADF, and energy in field peas fed to growing pigs. Five pea-containing diets were formulated. The peas included in these diets were either not heat-treated (control) or extruded at 75, 115, or 155 degrees C or pelleted at 75 degrees C. A N-free diet was also included in the experi...

A 42-d trial was conducted to study the influence of 2 plant extracts on performance, digestibility, and digestive organ weights in broilers. The feeding program consisted of a starter diet until 21 d and a finisher diet until 42 d. There were 4 treatment groups: control; 10 ppm avilamycin (AB); 200 ppm essential oil extract (EOE) from oregano, cinnamon, and pepper; and 5,000 ppm Labiatae extra...

the scope for using sunflower cake in ration formulation was tested in 6 horses employed for equine tourism. three experimental diets providing the same amount of proteins and energy as the control diet were formulated using rising doses of sunflower cake (sd3: 0.3 kg; sd6: 0.6 kg and sd10: 1.0 kg). digestibility evaluation using internal markers showed that rising sunflower cake doses reduced ...

Nicholas, BUTA-B6 and BUTA-T2 strains (A, B, and C) were reared in a total of 24 floor pens (0.309m2/bird) and fed commercial diets until 19 wk of age. The basal feeding program (calculated analysis) included a pre-starter (0-3 wk; 28.3% CP; 1.51% Ca; 1.04% tP), starter (3-6 wk; 27.8% CP; 1.50% Ca; 1.03% tP), grower-I (6-9 wk; 24.5% CP; 1.48% Ca; 1.00% tP), grower-II (9-11 wk; 22.5% CP; 1.39% C...

objective: this study aims to evaluate the protective effects of american ginseng administered by gastric intubation on sperm vital quality in adult male rats treated with cyclophosphamide (cp). materials and methods: in this experimental study, 28 adult male wistar rats were assigned to four groups, seven rats in each. the animals allocated to control, cp treated, ginseng treated and cp-ginsen...

This study was conducted to compare carcass characteristics and physico-chemical meat quality in two different genotype ducks raised under identical feeding and rearing conditions. A total of ninety 1-d-old Korean native ducks (KND, n = 45) and commercial meat-type ducks (Grimaud, n = 45) were fed same experimental diets during 56 d and 42 d, respectively to obtain similar slaughter weights. Th...
