Variation in the yield and composition of milk throughout lactation in the guinea pig (Cavia porcellus)

Spontaneous intrauterine growth restriction due to increased litter size in the guinea pig programmes postnatal growth, appetite and adult body composition

“…Previous studies have reported that although mothers produce higher yields of milk in larger litters, the milk yield per pup is reduced, suggesting pups in larger litters may be ‘force’ weaned earlier in comparison with those from smaller litters 42 . Interestingly, dams in all litter size groups gained weight in lactation in the present study, in contrast to a previous report 43 …”

Cytology of Milk in Guinea Pigs

“…The mean of total cell counts of samples collected at 2 days after parturition was high. This was followed by a dramatic significant decrease at 6-8 days after par turition which is the period of the peak of lactation in the guinea pig [Mepham and Beck, 1973], Such a trend was also observed by Gupta et al [1971], though they found that there was no significant difference in cell counts in samples collected 3-4, 6-7 and 10-11 days after parturition. However, in view of the wide variation and the small number of animals used, it is difficult to establish any baseline values for total cell count, or to compare these results directly with that of Gupta et al [1971].…”

Changes in Milk Composition During Lactation in the Guinea-Pig, and the Effect of Prolactin

“…After an initial period of about 6 days of relative stability, milk Mepham & Beck (1973) but in the present studies [lactose] continued to fall.…”
