When the Wisconsin dairy sheep industry got started in the mid 1990s, cheesemakers had to get accustomed to a whole new source of milk. All were familiar with cow milk and some were familiar with goat milk. However, sheep milk was much more concentrated with about twice as much fat and 40% more protein that cow or goat milk. They also found that sheep milk responded differently in the cheese ma...

Hourly milk yields were obtained for nine consecutive hours at d 14 of lactation from 92 crossbred (four breed) sows during their first and second lactations. Additionally, milk yields were obtained at d 14 and 20 of lactation from 175 mature Yorkshire X Landrace sows for nine consecutive hours. Each measurement (4,806 observations) was obtained by weighing the pigs before and after each hourly...

Control of milk composition is of importance in dairy ewes because milk is mostly used for cheese making. Besides numerous factors that alter milk composition, knowledge on the effects of nutrition is useful for it concerns both yield and milk content. Furthermore, modification of nutrition is a powerful and short-term means of altering milk composition. Global effects of nutrition are to be se...

the objective of this study was to consider economic consequence of delayed conception of milking cows in large dairy farms in iran. optimum open days and milk production at peak were assumed to be 110 days and 45 kg respectively. price of milk, feed, semen and hormones were calculated based on average prices of autumn, 2013. results of this study showed that increasing days in milk (dim) from ...

OBJECTIVE This experiment was studied the effects of various levels of crude glycerin (CG) in dairy goat diet on daily intake, milk yield, milk composition, some physical properties and some quality changes of goat milk after sterilization. METHODS Twelve 75% Saanen dairy goats (body weight = 49±3 kg; days in milk = 60±12 d) were randomly assigned in a completely randomized design to evaluate...

Aim: Uttarakhand is a relatively new state and many cross bred cattle were introduced to boost the milk yield of the state. Despite all efforts the milk yield of dairy in Uttarakhand is comparatively low. In our study, we assessed the effect of heat stress on milk production, using thermal humidity index (THI) in high (cross bred cattle) and low milk producing (LMP) cows (native cows) in Dehrad...

Milk yield and composition data from 7 nursing Lusitano mares (450 to 580 kg of body weight and 2 to 9 parities) were used in this study (5 measurements per mare for milk yield and 8 measurements for composition). Wood's lactation model was used to describe milk fat, protein, and lactose lactation curves. Mean values for the concentration of major milk components across the lactation period (18...

Two experiments were conducted to determine whether exposure to a photoperiod of artificial long days in autumn increased milk yield in subtropical goats milked once (Exp. I) or twice daily (Exp. II). In Exp. I, starting at d 10 of lactation, 1 group of does was kept under naturally decreasing photoperiod (DD1X; n = 8), whereas the other group was submitted to an artificial photoperiod of long ...

In dairy cows, increased milking frequency (IMF) during early lactation stimulates an increase in milk yield that partially persists through the remainder of lactation. However, the effects of IMF on lactation performance and udder health of primiparous heifers have not been clearly established. The objective of this study was to determine the effects of IMF during early lactation on milk yield...

The objective of the study was to compare ranking of Sahiwal bulls selected on the basis of highest lactation milk yield of their dams with their estimated breeding values (EBVs) using an animal model. Data on 23,761 lactation milk yield records of 5,936 cows from five main Livestock Experiment Stations in Punjab province of Pakistan (1964-2004) were used for the study. At present the young A.I...
