This experiment was carried out to estimate the metabolizable energy (ME) requirements for meat quails from 1 to 14 days of age. A total of 1,140 1-day old meat quails were distributed in a completely randomized design, with five treatments (2,750; 2,850; 2,950; 3,050 and 3,150 kcal of ME/kg), six replications and 38 quails per experimental unit. There was linear reduction of energy levels in body weight, feed intake and weight gain of birds. The feed conversion ratio showed a […]

This trial was conducted to evaluate dietary yeast Saccharomyces cerevisiae as pro-nutrient for diets for Nile tilapia broodstock females and fingerlings. The trial was conducted in two phases at UNESP. Two groups of tilapia broodstock females (734.47 ± 202.08 g), GIFT genealogy, were fed with isoprotein (34% DP) and isoenergy (3400 kcal DE/kg) diets for 100 days, one with 2% autolized yeast and the other with no yeast. Broodstock females were naturally fecundated, and larvae, at the end of yolk […]

The objective was to evaluate the effects of natural pigments from marigold extract and paprika to Japanese quails fed sorghum-based diets. One hundred and eight Japanese quails (Coturnix japonica), with 98 days of age were distributed in a complete randomized design in a split plot arrangement, with five treatments and six replicates of six birds each. The experiment was divided into six periods of four days each, totaling 24 days. Parameters productive performance and quail egg quality were evaluated. Yolk […]

The aim of this research was to study the effects of three different management systems on growth and carcass quality of 61 Murciano-Granadina breed kids and their interaction with sex. In the extensive system, 21 kids were allocated to suckle from their dams on free-range pasture with no additional feedstuff. In the semi-intensive system, 20 kids were suckled from their dams and had access to alfalfa hay and cereal straw (no free-range pasture). In the intensive system, 20 kids were […]

The objective of this study was to develop calibrations to determine the concentration of some milk adulterants by using the automated methodology of Fourier Transform Infrared (FTIR). For construction of calibrations, samples were collected from 100 farms in the states of São Paulo and Minas Gerais. Samples were tainted with three different adulterants commonly used in the adulteration of raw milk: sodium bicarbonate (SB), sodium citrate (SC) and cheese whey (W). Each adulterant was used at three different concentrations (SB: […]

The objective of this trial was to evaluate the effects of the inclusion of calcium oxide (CaO) and/or L. buchneri (LB) on the losses and chemical composition changes of in natura and burned sugar cane silages. Silage treatments were: in natura sugar cane without additive (IS), with Lactobacillus buchneri (ISLB), with calcium oxide (ISCaO) equivalent to 1% of natural matter, and the combination of LB and CaO (ISLBCaO). Experimental design was completely randomized in a factorial scheme (2 × 4) […]

This study aimed to estimate the energy requirements for maintenance and gain of Japanese and European quails under growth housed in two rearing systems: floor pens and cages. To determine maintenance requirements, two experiments were conducted with birds housed in cages in environmental chambers (experiment 1) and in floor pens at room temperature conditions (experiment 2). The experimental design was completely randomized with four levels of feed supply (100, 75, 50 and 25%) and four repetitions. Energy requirements for maintenance […]

The objective was to evaluate the effect of four levels of ground corn supply on nutritional parameters, microbial synthesis efficiency and growing performance of beef heifers, at the rainy season. For such, 28 crossbred yearling heifers, with initial age of 16-17 months and initial weight of 255 ± 31.0 kg were distributed into five paddoks of B. decumbens, of 2.0 ha each, with average potentially digestible DM availability of 2,377.0 kg/ha. For each one of the lots, one of the […]

The effect of the additives Yucca schidigera (YSC) and zeolite (clinoptilolite) on digestibility, fecal texture and odor, blood parameters and urine pH of domesticated felines was evaluated. The experiment was conducted in a randomized block design, with twenty-one cats, in two periods, distributed in seven treatments: moist commercial feed (control); control + 125, 250 and 375 ppm YSC; and control + 0.5; 0.75 and 1.0 % zeolite. No differences were observed between the diets regarding apparent digestibility coefficients of nutrient, […]

The study was conducted to evaluate productive and reproductive performance of 52 crossbred Charolais × Nellore beef cows on natural pasture. The experiment started on August 04, 2003, when pregnant cows were uniformly distributed by weight and body condition at two stocking rates (CA280 = 280 kg LW/ha and CA360 = 360 kg LW/ha). Early weaning was imposed to 26 cows when calves reached average of 100 days of age and conventional weaning, when calves were approximately 180 days old. […]
