The main objective of this research work was to evaluate the performance of Santa Inês ewes according to their body condition score (BCS) at lambing. Data from 135 adult ewes, with singletons, were used. Ewes were divided into three distinct groups: 1) Bellow average: BCS less than 2.5 points (n = 44); 2) Average: BCS between 2.5 and 3.0 (n = 53); and 3) Above average: BCS greater than 3.0 (n = 38). The scale f...
The objective of this study was to evaluate the ruminal degradability of dry matter and crude protein of high moisture triticale silage ensiled with different chemical and biological additives. Urea, sodium benzoate and an enzyme-bacterial inoculant were used as treatments. Four samples from each treatment were incubated in rumen on four sheep. Effective degradability was estimated for ruminal passage rate of 2...
We aimed to evaluate environmental effects on pre-weaning traits of Santa Gertrudis cattle. We used 213 standardized records for adjusted 205-day weight at weaning (W205), average daily gain from birth to weaning (AGD), and number of days to gain 160 kg from birth to weaning (D160), obtained from the Santa Gertrudis Breeders' Association for animals born between 1990 and 1997. The files were edited with informa...
This work was carried out with the objective of evaluating the effects of different levels of replacement of whole grain corn by pelleted soybean hulls in high concentrated diet, without long fiber use, on intake, productive performance and economical viability of feedlot lambs production. Twenty four Texel lambs, 12 males and 12 females of the same age, with average weight of 23 kg, distributed in 12 stalls, i...

The objective of this study was to evaluate the nutrient intake and suitability test of the SRNS nutritional model for dry matter intake (DMI) and average daily gain (ADG), and Hankins and Howe equations to estimate the carcass and empty body chemical composition of 35 Santa Ines lambs, non-castrated, with initial body weight of 14.77 ± 1.26 kg and two months old. After 10 days of adaptation, five animals were ...
O objetivo deste trabalho foi avaliar as características de carcaça, de componentes não carcaça e qualidade da carne de bovinos da raça Nelore terminados em confinamento e alimentados com diferentes híbridos de milho (duro, semi duro e semi dentado) na dieta. Foram utilizados 27 bovinos com peso vivo médio inicial de 350 ± 24 kg e idade média de 24 meses, distribuídos em delineamento inteiramente casualizado, e...
Fish anesthesia is indicated for several management procedures such as capturing, biometry, tagging, transporting, physical examination, reproductive management and surgical procedures. In this study the dose of benzocaine hydrochloride necessary for tilápia (Oreochromis niloticus) anesthesia was determined through six phases with 240 fish. In each phase 40 fish were evaluated. The interval between phases was t...
