The presence of copper in cow’s milk has been reported by several investigators (l-5). The most extensive investigation was that of Supplee and Bellis (2) who determined the copper content of freshly drawn milk of a large number of cows fed on different rations. They found that the copper content per liter varied from 0.2 to 0.8 mg., with no apparent correlation between copper content and ratio...

Abstract Sweet potato has the potential to be developed for diversified food consumption programs as a source of carbohydrates, nutrients, with small risk failure, low production costs, various processed products, providers, industrial raw materials, and animal feed. This research aimed analyze sweet farming economically socially. The study was carried out quantitatively using survey method. co...

BACKGROUND AND OBJECTIVES Tannins are toxic polyphenols that either bind and precipitate or condense proteins. The high tannin content of some plants is the preliminary limitation of using them as a ruminant feed. So, the aim of this study was the isolation and characterization of tannic acid degrading bacterial strains from goat feces before and after feeding on Pistachio-Soft Hulls as tannin ...

In many countries, goat farming is the important part from the economy point of the view; especially in the Mediterranean and Middle East region. Goat farming is well organized in France, Italy, Spain and Greece (Park and Haenlein, 2006). Industrialization of the goat milk is not well successed because of its poor and insufficient volume. From 1990, interest in the goat milk production is incre...

Morphometric, metabolic, and behavioral modifications were studied in goat kids after maternal feed restriction during the last one-third of pregnancy. At birth, only kids from twin and triplet litters were studied [n=40 kids born to control dams (CONT) and n=38 born to restricted dams (REST)] and only males thereafter (n=13 CONT and 15 REST kids) until slaughter at 6 wk of age. Kids born to re...

Sixteen Boer goat doelings, 16 Spanish doelings, and 8 Angora doelings and 8 wethers, 283, 316, and 330 d of age initially (SEM = 5.0), respectively, were used to evaluate effects of nutrient restriction on heat energy (HE). During the first and second 10-wk phases, 8 animals of each breed were fed a 50% concentrate pelletized diet at a level adequate for maintenance and moderate energy accreti...

The fixed metabolizable energy (ME) values from the NRC do not represent the true ME values of the various feedstuff used in livestock rations. Therefore, a rapid and effective method for evaluating the ME value of forage crops is required for proper ration formulation to improve production efficiency. Dairy goat digestion trials were conducted as the in vivo reference using the method of Menke...

AIM This study examined the effects of creep feed (CF) supplementation (with or without Alfalfa) on the pre-weaning growth performance of nursing goat kids. MATERIALS AND METHODS A total of forty eight (48), 7 days old, single born kids (live weight 4.4±0.09 kg) were divided into three treatment groups, each containing eight males and eight females. All three groups had access to their dams' ...
