- Calcium salts of palm oil fatty acids for dairy cows: a productive, biochemical and physiological approach, AP.R
Abstract
The aim of this study is to evaluate the supplementation with calcium salt of palm oil (CSPO) in dairy cows grazing on tropical pastures. Three experiments will be conducted. In experiments 1 (Exp. 1), 2 (Exp. 2) and 3 (Exp. 3) supplementation levels with CSPO will be: T1 = Control (no added CSPO); T2 = 200 g/day; T3 = 400 g/day; and T4 = 600 g/day. In Exp. 1, 40 Holstein cows will be u...
- Introduction to system dynamics for animal production, AV.EXT
Abstract
The Visiting Professor will work on a project approved by FAPESP which involves the study of energy supplementation of beef and dairy cattle grazing tropical pasture on metabolic parameters, ingestive behavior, ruminal fermentation, animal performance, milk composition, consumption, etc. In addition, the Visiting Researcher will teach a workshop on LRNS (Large Ruminant Nutrition System)...
- Microbial synthesis and rumen function in cattle, AV.EXT
Abstract
Professor Poppi will speak about Microbial Synthesis in Beef Cattle at the 50th Annual Meeting of the Brazilian Society of Animal Science and on the following week he will lecture at a short course for graduate students entitled Síntese Microbiana e Função Ruminal em Bovinos. The course will be held at ESALQ in Piracicaba-SP. The classes will be on the same topic of his speech and also ...
- Mathematical modeling applied to animal production, AV.EXT
Abstract
The visiting professor will work on two research projects approved by FAPESP. The first project involves grain processing methods (cracked and flaked corn) and forage fiber levels of sugarcane bagasse on performance and metabolic parameters of finishing Nellore cattle. The second project involves the study of energy supplementation of beef and dairy cattle grazing tropical pasture on me...

- Performance and metabolism of early lactation feedlot cows receiving doses of calcium salts of fatty acids of PALMA oil associated or not with LYSOLECITHIN, BP.MS
Abstract
The objective of this study was to evaluate the effects of supplementation with calcium salts of palm oil (CSPO) with or without lysolecithin (LS) for feedlot early lactation dairy cows. For this, an experiment will be carried out, wherein the animals will receive forage ad libitum and 9 kg of concentrate supplementation with three doses of CSPO associated or not with LS: T1 = 400g CSPO...
- Calcium salts of palm oil fatty acids for grazing dairy cows on ruminal parameters, BP.IC
Abstract
The aim of this study is to evaluate the supplementation with calcium salt of palm oil (CSPO) in dairy cows grazing on tropical pastures. Eight rumen-cannulated cows (15 LD) will be used in a repplicated Latin square design, wherein will be measured ruminal parameters: pH, amoniacal N and short chain fatty acids. Data will be analyzed by SAS 9.4 (PROC MIXED). Significances levels will s...
- Supplementation with calcium salt levels of palm oil in tropical grazing dairy cows, BP.DR
Abstract
The aim of this study is to evaluate the supplementation with calcium salt of palm oil (CSPO) in dairy cows. Four experiments will be conducted. In experiments 1 (Exp. 1), 2 (Exp. 2) the supplementation levels with CSPO will be: T1 = Control (no added CSPO); T2 = 200g/day; T3 = 400 g/day; and T4 = 600 g/day. An additional level (T5 = 800 g/day) will be used in experiment 3 (Ex. 3). In E...
- Functional oils replacing monensin on digestibility, rumen metabolism and nitrogen efficiency use by dairy cows, BP.IC
Abstract
The aim of this study is to evaluate the replacement of monensin by functional oils(Cashew + Copaiba) on digestibility, ruminal fermentation and efficiency of N for dairy cows. In the experiment, four dry cows cannulated in the rumen will be used in randomized 4x4 Latin square. Each period will last for 20 days with 14 days for adaptation and 6 days of collection. The treatments are: a)...

- Should we feed supplemental fatty acids to early lactation dairy cows: does the fatty acid profile of the supplement matter?, BE.EP.DR
Abstract
Early-lactation cows usually enter a period of negative energy balance and fatty acid (FA) supplementation is a strategy that may increase energy intake and performance of these cows. Unfortunately, there is a shortage of reports in the published literature that have determined the effect of FA supplementation on early-lactation dairy cows. Importantly, we know of no reports in the publ...
- Distillers by products use in feedlot diet, BE.PQ
Abstract
The Post-Doctoral project proposed will be composed by 4 performance and 3 metabolism experiments with feedlot finishing cattle to evaluate corn distillers by-products produced in the USA and in Brazil. The Experiment 1 will be conducted at the Feedlot Research Center of the University of Nebraska - Lincoln. In this study, 60 feedlot cattle will be individually fed diets containing co...
- Different dietary conditions and their effects on the concentration of hydrogen and methane: and nitrate bromoetanosulfonate (BES), BE.EP.MS
Abstract
Methane production is part of the digestive process and ruminant occurs in the rumen. Strategies aimed at reducing enteric methane emissions from ruminants undergo dietary manipulation aimed at the use of hydrogen dissolved in the rumen. The main objective of this project is to evaluate whether different dietary conditions affect the concentration of hydrogen and methane production. Two...
- Manipulation of the concentration of hydrogen and methane production by the addition of medium-chain fatty acids, BE.EP.MS
Abstract
Methane is a by-product generated in the digestive process (fermentation) of ruminants which occurs in the rumen. The main objective of the project is to evaluate whether different dietary conditions affect the concentration of hydrogen and methane production. Two experiments will be carried out, the first refers to the assessment of whether or not the addition of sources of medium-chai...
