Increasing milk productivity by introducing promising technological methods for feeding livestock

Prevalence and reasons for introducing infants early to solid foods: variations by milk feeding type.

OBJECTIVE To examine the prevalence of, and mothers' self-reported reasons for, introducing solid foods to infants earlier than recommended (aged <4 months) and the variation in reasons for early introduction by milk feeding type. METHODS The study included 1334 mothers who participated in the national longitudinal Infant Feeding Practices Study II (2005-2007). Monthly 7-day food-frequency qu...

Feeding Livestock

CHEMISTS years ago developed methods by which they could analyze feeds and have the constituents sum to TOO percent. Chemists and physiologists concluded therefrom that protein, fats, carbohydrates, and certain mineral elements were the only nutrients animals required. Data from experiments made it clear, however, that the quality of the ration and its ability to promote growth could not be pre...

Factors Influencing Livestock Productivity

Numerous factors affect livestock production and productivity. In this chapter we will address those that are of paramount importance: climate, nutrition, and health aspects. In initial section we will review the effects of climate on livestock productivity and provide examples of livestock adaptation to climate constraints such as the Bos indicus cattle breeds adapted to hot weather and the fa...
