ABSTRACT This study aimed to evaluate effects of an emulsifier based on glyceryl polyethyleneglycol ricinoleate in diets containing deactivated full-fat soybean (DFFS) on performance, relative weight of pancreas, pancreatic lipase activity, intestinal morphometry, serum lipid concentration, nutrient digestibility, carcass yield, and meat quality of broiler chickens. Three hundred fifty-two male broilers (one-day-old) were randomly assigned to two dietary treatments including a diet containing DFFS without the emulsifier and a diet containing DFFS with emulsifier (350 g ton−1). Each treatment had […]

ABSTRACT The objective of this work was to evaluate the composition of macro- and microelements in samples of bee honey (Apis mellifera) produced in different floral resources: aroeira (Myracrodruon urundeuva), cissus (Cissus rhombifolia), eucalyptus (Eucalyptus spp.), orange (Citrus sinensis), and honey of Jataí (Tetragonisca angustula). The content of macro- and microminerals in the honey samples were determined by inductively coupled plasma-optical emission spectrometry (ICP-OES). The results showed concentration levels of macro- (Ca, P, K, Mg, and Na) and microelements (Al, […]

ABSTRACT This study investigates whether pre-pubertal scrotal circumference (SC) and anti-Müllerian hormone (AMH) concentrations indicate sexual precocity in Brahman and Simmental bulls. Fifty-three bulls (Brahman, n = 27; Simmental, n = 26) were used. Scrotal circumference was measured at three periods: pre-puberty (Brahman = 19.99±0.20 months; Simmental = 9.13±0.17 months), puberty (Brahman = 21.42±0.20 months; Simmental = 18.26±0.17 months), and post-puberty (Brahman = 33.34±0.55 months; Simmental = 24.07±0.17 months). A single sample taken at the pre-pubertal period was used for […]

ABSTRACT This study aimed to evaluate the effects of dried or rehydrated corn and sorghum grains on nutrient intake, performance, and economic analysis in high-grain diets (30:70) of Nellore bulls finished in a feedlot system. The experiment was completely randomized and replicated four times (two animals/pen), in which 32 Nellore bulls with an initial body weight (IBW) of 324.8±4.42 kg were fed in 16 pens according to the following treatments: rehydrated corn silage (RCS), rehydrated sorghum silage, dry corn grain, […]

ABSTRACT Two studies were carried out to investigate the effects of crude glycerin (CG) levels in feedlot sheep diets as a substitute for ground corn. In the first study, four castrated rumen-canulated sheep were used to assess the effects of CG on nutrient intake, digestibility, rumen characteristics, and blood glucose. In the second study, 40 crossbred female lambs were employed to evaluate the influence of CG levels in the diet on nutrient intake, digestibility, and animal performance. Crude glycerin levels […]

ABSTRACT In this study, we investigated the effects of using poultry offal meal (POM) produced in rendering plants by adding dissolved air flotation sludge (DAFS) at set ratios into broiler grower and finisher feeds. The experiment conducted within the scope of the study lasted six weeks and involved 12,000 broiler chicks from Ross 308 strain middle-aged (36 weeks) breeders. Twelve different treatments were used in grower feed with 2 or 3% POM and finisher and pre-slaughter feeds with 4 or […]

ABSTRACT The objective was to describe the organizational structure of the Mangalarga herd and evaluate the influence of geographic distribution and different coats on the population structure and genetic diversity. Genealogic data of horses born between 1919 and 2018 were submitted to the software ENDOG 4.8, corresponding to the total population (TP), and those born between 2009 and 2018, representing the reference population (RP). Wright’s fixation index, inbreeding coefficient (F), and average relatedness (AR) were estimated considering each Brazilian state […]

ABSTRACT This study was conducted to determine the effects of adding pomegranate peel and oregano pulp at different levels (2, 4, 6, and 8%) on a dry matter basis to sheep rations on methane production and rumen fermentation using the in vitro gas production technique. In the study, nine experimental groups were formed by adding different levels (2, 4, 6, and 8%) of pomegranate peel and oregano pulp to the total ration mixture (control ration). Each treatment group was designed […]

ABSTRACT The present study aimed to evaluate the effectiveness of the grain processing carried out by a device containing round and oblong holes attached to the inside of the forage harvester and evaluate its impact on the nutrient composition of corn silage, animal productivity, feeding behavior, apparent digestibility of the diet, and carcass traits of feedlot finished steers. The silages tested were: silage subjected to the grain processor (SGP) and silage not subjected to the grain processor (SNGP), which also […]

ABSTRACT Two experiments were carried out aiming to evaluate the effect of copaiba oil on growth performance, apparent digestibility of nutrients, and rumen fermentation in lambs on feedlot. The treatments were: no additive inclusion (negative control); 8 mg/kg of sodium monensin (MS; positive control); and 250, 500, and 750 mg of copaiba oil/kg dry matter added to a diet with 70% concentrate and 30% forage. In experiment I, five lambs (Dorper × Santa Inês) cannulated in the rumen, 8 ± […]
