Food processing and consumption by herbivores are affected differently the availability of forage quality quantity per unit time. This demonstrates “Allometric response concept”, it is considered a significant determinant in habitat use for foraging grazers. The relevance this approach has comprehensively been applied to different body sizes, but little known about its demonstration explain pat...

Bloat is a disorder of ruminants caused by retention of gas in the stomach. Gas is produced continuously and in large amounts in the ruminant stomach and is eliminated normaUy by the animal without difficulty. Sometimes, however, the rate of elimination falls behind the rate of production so that gas starts to accumulate in the rumino-reticulum (hereinafter called the rumen). If the disparity c...

A study was conducted to determine the effect of conjugated linoleic acid (CLA) synthesized from sunflower oil on growth, carcass characteristics and meat quality of heavy pigs. Thirty-six pigs, half barrows and half females, averaging 97 kg L.W., allotted within weight and sex to a randomized complete experimental design, were fed diets supplemented with different CLA levels: 0.5% lard (C), 0....

Abstract Lumpy skin disease (LSD) is a threatnening caused by virus that affects large ruminant animals mainly cattle. LSD native in many African and Asian countries, having existed for over one hundred years Africa where it originally started has recently expanded to the Middle East region. A model consisting of six-dimensional system ordinary differential equations was formulated properly und...

The effect of vitamin D source and time of feeding 25-OH vitamin D3 (HyD r ) on broiler production efficiency and carcass composition was studied. The first hydroxylation of vitamin D in the liver results in 25-OH vitamin D3 (25-OHD3); providing dietary 25-OHD3 to the bird reduces the need for this hydroxylation, potentially allowing for a more efficient use of vitamin D. The dietary treatments...

The recycling of rendered animal products back into the feed of ruminant livestock species has had a positive impact both on the efficiency of livestock production and the availability of meat and milk for consumers at an affordable price. Rendered animal products are distinguished by a high protein content containing amino acids that resist microbial degradation in the rumen, and for extracted...

Multiparous Holstein cows (n = 60) were used to determine effects of trace mineral source on oxidative metabolism, subclinical endometritis, and performance of transition cows. After a 1-wk preliminary period, cows were assigned randomly to one of 3 topdress treatments from 21 d before expected calving through 84 d post calving: 1) Inorganic sources based upon sulfates of Zn, Cu, and Mn (ITM); ...

T o conclude, I will return to the species with which I began. The few sucrose or fructose tolerance tests that have been conducted on human volunteers (Bu...
