Sources of variability in lactational performance [PDF]
Proceedings of the Nutrition Society, 1989 Variation in lactational performance comes about as a result of variation in the nature of the animal, its environment, or with time. Table 1 lists a variety of sources of variability, classified under broad headings of variation with the animal (species, breed and individual), with time and with various aspects of the environment. The list is probably

Streptococcus dysgalactiae Isolates at Calving and Lactation Performance Within the Same Lactation [PDF]
Journal of Dairy Science, 2007 The objective of the study was to investigate the association between early lactation Streptococcus dysgalactiae isolates and milk yield, somatic cell count (SCC), clinical mastitis, and culling in the same lactation. The 178 commercial dairy herds were randomly placed into 3 penicillin- or penicillin-dihydrostreptomycin-based dry-cow treatments and 3 ...

Intensive Nursing and Lactational Performance during Extended Lactation
Experimental Biology and Medicine, 1968 SummaryIntensive nursing (6 pups/6 intact abdominal-inguinal mammary glands, and replacing all 16-day-old litters every 4 days with 12-day-old foster litters) failed to prevent significant declines in mammary DNA, RNA, and litter weight gains between days 20 and 36 of lactation.
