Two experiments were carried out to determine nutritive value and verify performance of growing and finishing swine feed high moisture corn silage (HMCS) and reconstituted silage (RS) of higher oil corn. The digestibility assay was carried twelve cross breed barrow, were allotted in metabolism cages, in a completely randomized design. The values of digestible dry matter (DDM), digestible protein (DP), digestible starch (DS), digestible ether extract (DEE), digestible organic matter (DOM), digestible energy (DE) and metabolizable energy (ME) were for […]

This trial was carried out to determine the digestible lysine requirements of Nile tilapia juveniles. Ninety- six reverted fishes averaging initial weight of 5.72 ± 0.10 g were fed four diets (29.51% of crude protein and 3,235 kcal/kg of digestible energy) containing increasing levels of L-lysine HCl (0.1, 0.3, 0.5, and 0.7%), during 42 days. The following treatments were evaluated: dietary lysine levels of 1.04; 1.27; 1.51 and 1.741%. Fishes were allotted to 1000-L 16 tanks, as a completely randomized […]

The different levels of digestible energy on the performance of Nile tilapia (Oreochromis niloticus) fingerlings were evaluated. One hundred and twenty-five fingerlings averaging initial length and weight of 0.62±0.12 and 3.25±0.25 cm were allotted to 25 30L-aquariums, as a completely randomized design with five treatments and five replicates (an aquarium with five fingerlings was considered the experimental unit). The diets, formulated to be isonitrogenous (30% of digestible protein), isophosphorous and isocalcium, contained 3,300, 3,525, 3,750, 3,975, and 4,200 kcal/kg of […]

The trial was conducted to evaluate the performance and morphologic changes of gastrointestinal tract and economic analysis for broilers fed sorghum-soybean meal-based diets, supplemented or not with multienzymatic complex (xilanase, amylase, protease), in the starting (experiment I) and finishing (experiment II) phases. The experiment was analyzed as a randomized block design with a 3 x 2 factorial arrangement [three sorghum levels (0, 50, and 100%) x enzyme level (0 and 100%)]. The experimental unit was a box with 17 birds […]

The trial was carried out to estimate the requirements of total lysine for male European quails (Coturnix coturnix coturnix) from 21 to 49 days old. Three hundred and fifteen quails averaging 80 g BW were fed diets with corn, soy crumb and corn gluten crumb. The basal diet was not supplementated with L-lysine, containing 20% of crude protein, 2,900 kcal of energy metabolizable/kg and 0.9% of total lysine, supplemented with 0.125, 0.231, 0.357, and 0.483 g of L-lysine (79%), resulting […]

This trial was conducted to evaluate the dietary levels of digestible threonine for growing gilts on heat stress environment. Seventy crossbreed gilts averaging initial weight of 14.9 ± 0.56 kg were assigned to a complete randomized blocks design with five treatments (levels of digestible threonine) of seven replications (two animals per experimental unity). The treatments consisted of the following dietary digestible threonine levels: 0.538, 0.577, 0.614, 0.651, and 0.688%. Daily weight gain and threonine intake linearly increased as the dietary […]

A trial was conduced with to evaluate the levels of folic acid in diets supplemented with formic acid for piglets from 21 to 48 days old. 160 crossbred piglets were used with initial average weight of 5.67 ± 0,90 kg in a completely randomized experimental block design, with five treatments, eight replications of four animals each. Two basal diets with increasing formic acid levels (0.24 and 0.20%) were formulated (pre-starter I = from 21 to 35 days old and pre-starter […]

This study was carried out to evaluate the effect of environmental temperature on performance, carcass composition and physiological parameters of pigs from 30 to 60 kg of weight. Thirty six barrow (Landrace x Large White) with initial weight of 29.94 ± 0.49 kg, were assigned to a completely randomized experimental design with three treatments six replicates and two animals per experimental unity. The experimental period lasted 35 days. The treatments consisted of T1 Animals on heat stress (32ºC) fed ad […]

This study was conducted to evaluate the effects of high moisture corn and high moisture sorghum versus corn and sorghum grains on intake and production of feedlot lambs. Confinement lasted 77 days and was divided in two periods as follows: in the first 35 days elephant grass (Pennisetum purpureum Schum.) was used in a forage:concentrate ratio of 50:50 while Brachiaria-grass (Brachiaria brizantha) hay was used in a forage:concentrate of 30:70 in the remaining 42 days. Animals were blocked by weight […]

The objective of this trial was to evaluate the effects of different physical forms of soybean on average daily weight gain (ADWG), final body weight (FBW), carcass yield (CY), ruminal pH, and ruminal ammonia concentration on crossbred steers fineshed at pasture. Animals were fed three times per week a supplement containing a mineral mix and one of the following protein sources: ground whole soybean (GWS), whole soybean (WSB) or soybean meal and ground corn (SMGC); steers on control treatment received […]
