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 […]

The objective of this trial was to compare the effect of compensatory growth regime on the metabolic profile and mammary gland development of dairy heifers. Twenty Brown-Swiss heifers averaging 200 kg of body weight and five months of age were used in a completely randomized design with a 2 × 2 factorial arrangement. The treatments were arranged in a factorial arrangement (2 × 2) and the animals were randomly allocated in each one of the combinations. The factor 1 consisted […]

The objective of this trial was to compare the effect of different feeding strategies with or without ionophore (monensin) supplementation on performance of dairy heifers. Twenty Brown-Swiss heifers averaging 200 kg of body weight and five months of age were used in a completely randomized design with a 2 x 2 factorial arrangement of treatments. Treatments were: two feeding regimes (conventional vs. compensatory growth) with (200 mg/animal/day) or without monensin supplementation. Animals in the conventional feeding regime were fed ad […]

This experiment was conducted to evaluate the performance, control of the of metabolic diseases incidence, and carcass yield of male broiler chickens allotted to a feed restriction from 8-14 days of age. The nutrient restriction was achieved by feeding a starter diet (21,5% CP and 3050 ME, kcal/kg) with 25 or 50% soybean hulls. The treatment of restriction involved the feeding of these diets either on continuously or intercalated form (with the non-diluted starter diet). After the restriction period, the […]

The objective of this work was to present a reparametrization of a means deviation model from contemporary groups up to an unrestricted animal model (Lush’s mixed model equations – LMME). Applying restrictions on the LMME, the animal model was obtained in accordance with Henderson (Henderson’s mixed model equations – HMME). To obtain the HMME, restrictions of the type were imposed and these demanded the necessity of unrealistic assumptions, as the absence of selection, so that the HMME properties could be […]
