Abstract

This chapter presents the energy, protein and mineral requirements of lactating Nelore cows and calves. Various models and techniques used to estimate the nutrient requirements, milk production and milk composition are discussed.

AbstractFull Text

Management methods have been shown to greatly synchronize grazing behaviour. Dairy cows can be expected to anticipate being moved to a fresh paddock after milking and synchronize their behaviour to this prediction. This results in reduction of grazing time and intake. This experiment was to test...

Abstract

This paper presents the development of low-cost feed mixture to supplement the diet of dairy cattle during the dry season in Brazil. Results of trials indicate that the feed based on sugarcane and urea promotes weight gain and increase in milk production. The feeding system requires neither a great ...

Records of 152 145 test-day (TD) milk yields, from 7,317 complete first lactations of Holstein cattle raised in Brazil were analysed. Estimate covariance functions for additive genetic and permanent environmental effects, as well as the genetic parameters for TD milk records using random regression ...

AbstractFull Text

Individual inbreeding coefficients (F) were estimated for 27 610 animals of Gyr Dairy Cattle and distributed in 29 classes (CF). Despite the low values of the average F (2.82%), 60% of the population is inbred, a percent considered worrying. Records of 24 405 lactations from 8,879 cows were used to ...

AbstractFull Text

The objective of this research was to estimate the values of the components of (co)variances, herdability and genetic and phenotypic correlations for the traits milk yield at 210 days of lactation (PL210) and milk yield at 305 days of lactation (PL305) on animals Caracu breed. The data used were...

AbstractFull Text

Data of 3,849 lactations of Guzerat cows from many regions of Brazil were used. Genetic evaluations considered 52 sires tested by progeny (PT) and 40 within MOET nucleus (MN) based on full-sib families. Genetic parameters (GP), breeding values (BV) and reliabilities (R) for milk (MY) and fat (FY)...

AbstractFull Text

Records of 6604 test day to milk yield were analysed in the first lactation of 876 cows of Girolando breed, obtained from 1989 to 2001, from the Girolando's Brazilian Association. Seven types of measurement were analysed for lactation persistence using the genetic values of milk production of the...

AbstractFull Text

The objective of the research was to estimate genetic parameters, such as heritabilities and genetic and permanent environmental correlations for nine measures of milk persistency, using the random regression test day model (RRM). The data used were the 395 734 first 3 lactation test day milk yield ...
