Rate Of Accumulation

Serial measurements of udder volume in 11 multiparous and 4 primiparous Jersey cows in mid-lactation were used to establish the time of cessation of milk production after a period of milk accumulation. Udder volume was determined from measurements of udder height, length and width. Functional udder capacity (defined as the litres of contained milk in the udder when milk secretion ceased) was greater in cows (15.5 � 0.8 litres) than heifers (9.3 � 0.7 litres). Expressed as hours-worth of secretion, on average, heifers possessed 25.9 � 1.5 and cows 33.6 � 2.9 hours-worth of capacity - data which indicate some potential for reduction in milking frequency without loss of production. Functional udder capacity (l.) was correlated with empty udder volume (tissue volume), and was greater in cows showing high residual milk volumes. The data show that once functional capacity is reached the shut down in milk secretion is rapid, occurring over a 2-4 h period, the rate of accumulation of secretion being constant up to this time.

Diet Supplementation

The aim of this research was to enhance the nutritional quality of ewe milk fat by increasing potentially healthy fatty acids (FA) through diet supplementation with unprotected oil rich in linoleic acid, and without detrimental effects on animal performance. Twenty-four ewes were assigned to two high concentrate diets, control or supplemented with 6% sunflower oil (SO), for 4 weeks. No differences between treatments were found in milk production and dry matter intake. Although the SO diet increased milk fat percentage and tended to reduce milk protein concentration, it did not affect milk fat, protein or total solid yield. Most of the modifications in milk FA composition were addressed toward a potentially healthier profile: a decrease in C12:0 to C16:0 and a remarkable increase in the contents of cis-9 trans-11 C18:2 (from 0·94 to 3·60 g/100 g total FA) and trans-11 C18:1 (from 2·23 to 8·61 g/100 g total FA). Furthermore, the levels reached were maintained throughout the period monitored. However, the SO diet increased other trans C18:1 isomer percentages, too. The lack of differences between treatments in the in vitro ruminal fermentation parameters, studied with batch cultures of rumen microorganisms, would indicate no negative effects on ruminal fermentation.
