ABSTRACT The INTERGEN package has been under constant development for the last two decades using the Fortran 90/95 programming language. The latest version of INTERGEN includes three different binaries: intergen, intergeniod, and intergenacc. Intergen has been consistently expanded to include the Best Linear Unbiased Prediction (BLUP) genomic module in recent years. The intergeniod and intergenacc binaries are new and aim to estimate genetic merit using iteration on data (IOD) and approximate accuracy. The present study aimed to provide a high-level […]

ABSTRACT The objective of this study was to evaluate the hepatic metabolism and performance of broilers fed reduced-energy diets (50 kcal/kg less), with or without guanidinoacetic acid (GAA). A total of 432-day-old male chicks of the Cobb 500 lineage were distributed in a completely randomized design with three treatments and eight replications. The treatments consisted of a basal diet (BD), basal diet with a reduction of 50 kcal/kg (RBD) and a basal diet with a reduction of 50 kcal/kg supplemented […]

ABSTRACT This study evaluated the effects of dietary crude protein (CP) and methionine (Met) levels on growth performance, feed utilization, and daily nutrient intake of juvenile Penaeus vannamei reared under 16 and 40 psu. A 2 × 3 × 2 factorial design tested six diets with CP levels (33.3 and 37.4%, as-is basis) adjusted via soy protein concentrate, and Met levels (0.6, 0.7, and 0.9%, as-is basis) supplemented with DL-methionine. Shrimp of 1.49 ± 0.11 g were fed for 91 […]

ABSTRACT This study aimed to evaluate the effects of backgrounding supplementation, by increasing the levels of energy-protein supplements during the growing phase on the performance and rumen morphometrics of Nellore bulls intensively finished on pasture. Ninety-six Nellore bulls were blocked according to initial body weight (BW) of 385.6 ± 7.3 kg and randomly assigned to one of 24 paddocks of Urochloa brizantha cv. ‘Piata’ (four animals/paddock). The animals were supplemented during the growing phase as follows: (1) energy-protein supplementation at […]

ABSTRACT This study aimed to characterize carcass, meat quality, sensory and textural parameters, as well as muscle fiber types from 16 Moura pigs, as a local pig raised in outdoor production system, and evaluate differences with 16 conventional commercial (CC) pigs, raised intensively, representing the principal pork type, widely available in national market. Carcass measurements, liquid loss and cooked pork texture tests, proximal composition analysis of pork and backfat, and sensory evaluations with 104 pork consumers were carried out. The […]

ABSTRACT This study aimed to describe the phenotypical and biometrical characteristics of Creole goats on the Tamaulipas Plateau (TP) and San Fernando Valley (SFV) agroecological zones in northeastern Mexico. Eight hundred fifty-eight goats (70 males and 788 females) were studied to collect qualitative and quantitative information. Data were analyzed for male and female goats separately using frequency and general linear models. Pearson’s correlation was used to analyze linear body measurements (LBM) for morpho-structural homogeneity. The canonical discriminant analysis and a […]

ABSTRACT The objective of this study was to evaluate the LBu 01 – CGMCC 19250 strain of Lentilactobacillus buchneri (LB) in whole-plant corn silage (WPCS) during different storage periods. The experiment was conducted in a completely randomized design with a factorial arrangement of treatments (2 × 3), two inoculant levels (control – without inoculant, and experimental – inoculated with 9 log CFU LBu 01/kg of forage), and three storage periods (3, 15, and 62 days). Dry matter (DM) losses, aerobic […]

ABSTRACT The current study evaluated the impact of aerobic exposure time (ET) and microbial inoculants (MI) on the fermentative and microbiological characteristics and the nutritional value of relocated whole-plant corn silage (WPCS). Treatments were arranged in a 4 × 5 factorial design: microbial inoculants (without inoculant (WI); L. plantarum (DSM3676; DSM3677) + L. buchneri (DSM13573) (LPLB); L. plantarum (MA18/5U) + P. acidipropionici (MA26/4U) (LPPA); and L. buchneri (DSM13573) (LB)) and non-relocated (NR) or relocated after 12, 24, 48, and 60 […]

ABSTRACT This study aimed to evaluate genotype × environment (G×E) interactions in Guzerá breed animals for 305-day first-lactation cumulative yields (kg) of milk (MY305), fat (FY305), and protein (PY305). We used 6823 records of MY305, 2466 records of FY305, and 1870 records of PY305. The contemporary groups (CG) were created considering herd and year of calving. The analyses were performed in two steps. In the first step, environmental effects on phenotypes were estimated by using a multi-trait model ignoring G×E […]

ABSTRACT The objective of this study was to evaluate the associations among forage production related traits in Paspalum nicorae Parodi ecotypes and employ BLUP multi-trait path analysis as a selection criterion. Eighty-four ecotypes were grown in a randomized block experimental design with four replications and measured for three years. Measurements included number of tillers, fresh matter, leaf dry matter, stem dry matter, inflorescence dry matter, total dry matter, leaf:stem ratio, harvest index, cold tolerance, forage persistence, growth habit, and plant […]
