TL;DR: Goats are less sensitive to copper toxicity than sheep and cattle and can tolerate higher levels of Cu in their diets than other ruminant species such as cattle and sheep as discussed by the authors.

TL;DR: In this paper, the effect of inorganic, organic and elemental nano-selenium on growth performance, Se concentration and antioxidant status in growing male goats was studied, and the results showed that the final BW was increased.

TL;DR: In conclusion, selenium deficiency resulted in abnormal spermatozoal mitochondria, and supplementation with nano-Se enhanced the testis Se content, testicular and semen GSH-Px activity, protected the membrane system integrity and the tight arrayment of the midpiece of the mitochondria.

TL;DR: It is concluded that Zn-Met supplementation can enhance resistance to udder stress in dairy goats and improve Zn retention and protein utilization by the ZN-Met supplement.
Abstract: Twenty-two Murciano-Granadina dairy goats were used to investigate the effects of organic Zn supplementation of a diet containing a high level of inorganic Zn. Goats were kept in pens, machine milked once a day throughout lactation and fed a diet based on a dehydrated mixture of whole-plant maize and alfalfa ad libitum, alfalfa pellets, barley grain and a concentrate mixture. Treatments were: (1) control, and (2) supplemented with 1 g/d Zn-Methionine (Zn-Met) included in the concentrate mixture. After parturition, goats were blocked in week 3 and dietary treatments were applied until week 23. From weeks 3–20, feed intake, milk yield, milk composition, milk somatic cell count (SCC), and udder health were measured. In week 21, all goats were injected intraperitoneally with 1 g/d DL-methionine for 5 d to establish the effects of methionine under the conditions of udder stress induced by hand milking on the second day. During weeks 22 and 23, diet digestibility, and N and Zn balance were determined. Dry matter intake, milk yield, and milk contents of total solids, fat, total and true protein, and casein did not differ between treatments, but whey protein and non-protein nitrogen contents were significantly lower for the Zn-Met group. Milk SCC tended to decrease as a result of Zn-Met supplementation but differences between treatments were not significant when halves with persistent infection were excluded. Hand milking increased SCC in both groups, but udders of supplemented goats showed a lower reaction. Apparent absorption of N significantly increased and Zn retention tended to increase in Zn-Met supplemented goats. We conclude that Zn-Met supplementation can enhance resistance to udder stress in dairy goats. Effects were attributed to the organic Zn and not to the methionine component. Zn retention and protein utilization were also improved by the Zn-Met supplement.

TL;DR: It is indicated that goats are more resistant to Cu toxicity than sheep, and feeding goats 50mgCu per day or more, resulted in an increased plasma GGT as compared to BD goats.

TL;DR: The injections of Se plus vitamin E significantly increased the incidence of oestrus, fertility and prolificacy in ewes, lamb body weight at day 60 and daily weight gain of eWes for 60 days postpartum compared with the control group.
Abstract: The experiment was conducted on 90 Karacabey Merino ewes divided into three groups. The first group of ewes was treated with 5 mL 0.1% sodium selenate, the second with 5 mL 0.1% sodium selenate and 250 mg vitamin E, while the third one was a control group. The effect of intra-muscular injection of selenium (Se) and Se plus vitamin E on oestrus, fertility, prolificacy, number of lambs reared the weight of lambs at birth and the live weight gain for 60 days was investigated. The injections of Se plus vitamin E significantly increased the incidence of oestrus, fertility and prolificacy in ewes, lamb body weight at day 60 and daily weight gain of ewes for 60 days postpartum compared with the control group.
