“…Serum Zn concentration of blackbuck is not known. However, serum concentration of zinc below 1.2 mg/l has been reported to be inadequate for the maintenance of goats (Ahmed et al., 2001). The roughage‐only diet was not able to supply adequate amount of Zn to maintain such serum concentration of this element.…”

A feeding trial was conducted to know the level of concentrates in the diet of Antelope cervicapra at which diet digestibility and mineral utilization were optimum. Fifteen blackbucks (25-33 kg BW) were distributed into three groups of five each. Fresh oat (Avena sativa) and berseem (Trifolium alexandrinum) fodders were offered ad libitum to all the animals. In addition, animals in groups II and III received concentrate mixture at the rate of 0.5 and 1% of BW, whereas animals in group I received no concentrates. As the level of concentrates increased, consumption of fodder decreased resulting in decreased consumption of neutral detergent fibre (NDFom), acid detergent fibre (ADFom), hemicellulose and cellulose. However, overall total dry matter (DM) and organic matter (OM) intake was not significantly different between the groups. Digestibility of DM, OM and gross energy (GE) increased while that of NDFom and ADFom decreased with increased level of concentrates in the diet. Intake of P, Zn, Cu and Mn increased with increased level of concentrate supplementation; however, consumption of Ca and Fe followed the reverse trend. Absorption of P and Zn increased with increased level of concentrate supplementation. Serum concentration of Zn increased when concentrate was supplemented at the rate of 0.5% BW beyond which there was no further improvement. Increasing the level of concentrates in the diet was resulted in increased serum glucose and cholesterol levels. Forage-only diet was inadequate in supply of energy, P and zinc. Supplementation of concentrates at the rate of 0.5% BW was able to meet the requirement of these nutrients. Supplementation at the rate of 1% BW supplied energy and P in excess of requirement. It was concluded that the feeding of concentrates to the captive blackbuck fed forage-based diets should be restricted to 0.5% of BW.

“…Different physiological status such as age, sex, breeding season, lactation, and pregnancy would impose certain demands on animals need for trace elements, and hence, adequate amounts in the diet should be accounted for to achieve the best animal performance [11,12]. Rabbits breeding considered very important specially in developing countries as a source of animal protein.…”

Trace elements such as Zinc (Zn), copper (Cu), iron (Fe), and selenium (Se) are essential for male fertility. The fertilizing capacity of most animals reduced with advancing age. The objective of the present work was to determine the serum and testicular levels of Zn, Cu, and Se in young (10 months old) and old (30 months old) rabbits. Blood and testicular samples were obtained from rabbits after their slaughter. All samples were digested by concentrated acids and analyzed for trace elements by flame emission atomic absorption spectrophotometer. The results showed that serum Zn and Cu were lower in old rabbits than young (P < 0.01). Serum Se was higher in old than young rabbits (P < 0.05). Testicular Cu and Se were significantly lower in old than young rabbits (P < 0.01). However, Zn level was higher in old compared to young rabbits (P < 0.01). The serum Zn and Se were higher than the testicular levels (P < 0.01). The testicular Cu in both ages was higher than the serum level (P < 0.01), which suggest a very important role for Cu in the process of spermatogenesis in rabbits.
