Made available in DSpace on 2021-06-25T10:29:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; This study aimed to evaluate the effect of substituting corn with wheat middling on the in-situ degradability of foods and ruminal parameters of cattle. The experiment was conducted at the Ruminant Studies Unit and the Laboratory of Food Analysis and Animal Nutrition of Londrina State University. Five r...

Effects of replacing Tifton-85 hay by cactus pear (Opuntia stricta Haw) on the ...

The objective of this study was to evaluate the carcass traits of crossbred Santa Inês lambs fed with increasing levels (0, 300, 600, and 900 g kg-1 on a dry matter basis) of cactus pear cv Mexican elephant ear (Opuntia stricta Haw) as a replacement for Tifton-85 hay. Forty-eight male lambs (noncastrated), averaging 21.0 ± 2.93 kg body weight (BW) at the beginning of the study, were used in this trial. Replacem...

Bioeconomic efficiency of lamb finishing production systems

This study aimed to evaluate the production performance, quantitative carcass characteristics, and economic viability of lambs of genetic group Pantaneiro finished under four production systems: 1) Stockpiled Brachiaria brizantha cv piatã pasture; 2) Consortium of sorghum intercropped with Brachiaria brizantha cv piatã; 3) Feedlot based on sorghum silage and 2% body weight energyprotein supplementation, 4) Feed...

Ruminal degradability of high moisture triticale (X. Triticosecale Wittmack) si...

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...

Cinética de degradação ruminal de silagem de capim-elefante com diferentes níve...

Objetivou-se com este estudo avaliar a cinética de degradação ruminal in situ em dois experimentos, os quais utilizaram níveis de jaca desidratada (0, 5, 10 e 15% na matéria natural) e raspa de mandioca (0, 7, 15 e 30% na matéria natural) na ensilagem do capim elefante. Os dois experimentos foram realizados no Departamento de Zootecnia da Universidade Federal de Viçosa, no mesmo período e seguiram o mesmo proto...

Method to generate growth and degrowth models obtained from differential equati...

This study aims to propose a method to generate growth and degrowth models using differential equations as well as to present a model based on the method proposed, compare it with the classic linear mathematical models Logistic, Von Bertalanffy, Brody, Gompertz, and Richards, and identify the one that best represents the mean growth curve. To that end, data on Undefined Breed (UB) goats and Santa Inês sheep fro...

Intake, apparent nutrient digestibility and ingestive behavior of sheep fed cas...

Objetivou-se avaliar o consumo, a digestibilidade aparente dos nutrientes e o comportamento ingestivo de ovinos alimentados com rações contendo farelo de castanha de caju (FCC) nos níveis de 0; 10; 20 e 30% na ração concentrada. O delineamento experimental utilizado foi quadrado latino 4 × 4 duplo. Os consumos de matéria seca (MS), matéria orgânica, proteína bruta, matéria mineral, carboidratos não-fibrosos e n...
