ABSTRACT This study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.

ABSTRACT: Inherently, ruminant production of methane (CH4), a greenhouse gas (GHG), causes animal energy losses. Cottonseed is a lipid source and is used sometimes to enhance energy density in cattle diets. It also can mitigate enteric CH4. Lipids release peroxides in the rumen, and antioxidants have the ability to neutralize them. Thus, a lipid and antioxidant source can benefit rumen fermentation. The aim of this study was to evaluate rumen fermentation parameters from cows fed cottonseed and vitamin E. Six cannulated cows were arranged in a replicate 3 × 3 latin square. Treatments were: 1) Control, 2) CS (30 % corn replaced by cottonseed) and 3) CSVitE (30 % corn replaced by cottonseed, plus 500 IU VitE). Results were compared by orthogonal contrast....

CRAMBE CAKE (Crambe abyssinica hochst) ON LAMB DIETS
Provedor de dados: 64
Autores: Canova,Érika Breda; Bueno,Mauro Sartori; Moreira,Heverton Luis; Possenti,Rosana; Brás,Patrícia.
The use of alternative feedstuffs in animal diet, such as residues derived from the biodiesel production aims to increase productivity and reduce costs in animal production. Them aim of this study was to evaluate the substitution effect of 0, 22, 44 and 64% of soybean meal protein by Crambe cake (Crambe abyssinica Hochst) protein in lamb diet. In the in vivo experiment, 20 lambs were used and evaluated the apparent digestibility, nitrogen balance and voluntary DM intake. The replacement of the protein resulted in a linear decrease in apparent digestibility coefficient (ADC) of dry matter (DM), organic matter (OM), ether extract (EE), gross energy (GE), acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose (CEL) and the percentage of total...
