This study was carried out to evaluate the effects of different levels of standardized ileal digestible (SID) methionine + cystine (Met + Cys) and vitamin B6 supplementation on the carcass characteristics and longissimus lumborum (LL) quality in gilts from 75 to 100 kg. Fifty-six gilts were used (Talent x Topigs 20), with an initial average body weight of 75.06 ± 1.68 kg, allotted in a completely randomized blo...

Two experiments were carried out to determine the performance of rabbits fed on diets including cassava hulls dried (CHD), fiber variety for growing rabbits. In the digestibility assay, 22 rabbits at 50 days of age were used in a randomized design with two treatments and 11 replicates. Reference and test diets were used in which CHD substituted 25% of dry matter of control diet. The digestible values of the dry...
The study aimed to evaluate the effect of cassava root meal on the growth of rabbits. Two experiments were carried out. Digestibility assay was conducted using 22 rabbits with 50 days of age, in a randomized design, with two treatments and 11 replications. Reference and test diets were used in which CM substituted 25% of the control diet dry matter. The digestible dry matter values, protein, neutral detergent f...
A performance trial was carried out to determine the total lysine requirement of growing-finishing pigs (35.1±3.35 a 84.7±7.09kg), fed low protein diet, formulated according to ideal protein concept. It was used 32 barrows, 16 pigs from a common genetic group (CGG) and 16 from an improved genetic group (IGG). The treatments consisted of four diets (0.75, 0.90, 1.05 and 1.20% of total lysine in the...
To determine calcium (Ca) and phosphorus (P) nutritional requirements, 512 laying Japanese quails were distributed in a completely randomized 4x4 factorial design (P levels available – 0.27%, 0.32%, 0.37%, 0.42%, and CA levels – 2.5%, 3.0%, 3.5%, 4.0%), with four replicates and eight quails per experimental unit. A linear interaction (p < 0.05) was observed between P and Ca levels for production percentage; the...
Two trial were carried out to determine the performance of rabbits fed on diets which included Leucaena hay (Leucaena leucocephala cv. Cunninghan). Twenty-eight 40-day old White New Zealand rabbits were employed for the digestibility trial, in a completely randomized design with two treatments and 14 replications. Reference and test diets were used in which Leucaena hay replaced 25% of the dry matter in the ref...
Two trials were carried out to study the energy restriction (3200, 2960 and 2720 kcal of ME kg-1) for late finishing pigs, by means of adding dietary fiber (ground rice hull). Experiment I - 36 pigs were used (69.39 ア 5.38 kg). The variables studied (performance, carcass traits and PUN) were separated according to the slaughter weight (70-90 kg and 90-115 kg). 12 pigs weighting 87.55 ア 3.12 kg and 15 pigs weigh...
