Utilization of nitrogen and energy from diets containing protein and fat derived from either goat milk or cow milk.

Consumption of whole milk and related dairy products has decreased considerably as a result of negative aspects associated with the consumption of saturated fats. The main difference between the composition of goat milk and cow milk concerns the composition of the fat, that of goat milk containing a larger proportion of medium-chain triglycerides. The metabolic utilization of these compounds is fundamentally oriented towards their use as sources of energy, and they may even contribute to the synthesis of proteins.

Milk production and composition in Malagueña dairy goats. Effect of genotype for synthesis of alpha s1-casein on milk production and its interaction with dietary protein content.

A study was carried out to analyse the production and composition of milk from Malagueña goats of different genotypes for the content of alpha s1-casein. Twenty goats were used, half of them with a high (HG) and half with a low (LG) genetic capability for alpha s1-casein synthesis. Among the ten HG goats, seven had BB and three had AB genotypes, whereas there were seven EF and three FF genotypes among the LG goats.

Physiological responses of pre-ruminant kid goats and lambs to different environmental temperatures.

The purpose of this study was to establish the metabolic behaviour of both preruminant kid goats and lambs, when they are kept at different environmental temperatures (12, 24 and 30 degrees C). The animals were fed ad libitum with a milk replacer for the first two months of life. Blood samples were taken from all the animals on days 30, 40, 50 and 60 post partum, to determine serum levels of glucose, insulin, free fatty acids, triiodothyronine (T3) and thyroxine (T4), both when fasting and 4 hours after starting feeding.
