Comparison of lactation curve models for fortnightly test day milk yield
Indian Journal of Animal Sciences, 2020 The study of lactation curve helps to predict lactation milk production at a certain point of time and provides useful information for taking desirable decisions on preliminary sire evaluation, early culling of poor producers, breeding and feeding ...

Non-nutritional factors affecting lactation persistency in dairy ewes: a review
Italian Journal of Animal Science, 2010 Milk production is largely related to the shape of the lactation curve. Key elements of the lactation pattern are peak yield, which is the maximum daily yield reached during lactation, and lactation persistency, which is the medium rate of milk yield ...

Comparison of different lactation curve models to describe lactation curve in Awassi sheep raised in Turkey [PDF]
Applied Ecology and Environmental Research, 2019 The study was carried out in the International GAP Agricultural Research and Training Centre (GATEA) between the years 2010-2014 in Diyarbakır, Turkey. The aims of this study were 1) to compare 8 different models (MG, Dhanoa, Nelder, Wood, CLD, and 2nd-, 3rd-and 4th-degree polynomial) used to describe the lactation curve for Awassi sheep by using 557 ...

Comparison Between Different Functions of the Lactation Curve [PDF]
The Egyptian Statistical Journal, 1996 Six mathematical functions; Wood, Mitscherlich* exponential, Michaelis-Menten* exponential, Logistic* exponential, Weibull* exponential and Multiphasic; were used to describe the lactation curve of the monthly test- day average of 12020 Holstein Fresian ...
