The effect of fetal number (single or twin) on plasma concentrations of progesterone, estradiol 17β, cortisol, prolactin, growth hormone, triiodothyronine, thyroxine and insulin around parturition (periparturient period) were studied on ten Alpine × Beetle crossbred goats in their first to third lactation. The hormone profiles were studied on days -20, -15, -10, -5, -4, -3, -2, -1 prior to kidd...

Data from 1279 lactations of 783 Alpine and Saanen goats of the herd of our university in Minas Gerais, Brazil, were used to study environmental effects on and to estimate genetic parameters for milk production until 270 days of lactation (MP270) and for production and percentages of fat (PFAT and %FAT), protein (PPROT and %PROT), lactose (PLACT and %LACT), and total dry extract (PEXTR an...

An experiment was carried out to evaluate the effect of mineral supplementation on post-parturient complication in pregnant goats and perinatal mortality in their kids. The study revealed increased in survival percentage of kids and reduced post parturient complication during kidding in mineral supplemented group than non supplemented group. From the present study it is concluded that the suppl...

The aim of this study was to identify risk factors for culling, sales and deaths in intensively managed dairy goat herds in New Zealand. A data set provided by the New Zealand Dairy Goat Cooperative (n = 13,197 does) was analyzed using a Cox proportional hazard model. The outcome of interest was length of productive life (LPL), defined as the number of days from the date of second kidding to th...

In this study, breeding objective traits were identified, and alternative schemes simulated evaluated for two goat populations. The as follows: body size, twinning ability kidding interval (KI) Arab goats mothering Oromo goats. selection criteria six-month weight (6mw, kg), litter size at birth (LSB), weaning (LSW) KI (days).
