The influence of administration of biotin and zinc chelate (Zn-methionine) to cows in the first and second trimester of lactation on their health and productivity

Abstract

In cattle, the prevention of diseases might be possible using dietary methods, with nutritional optimization of feed rations. For years significant influence has been associated with the addition of biotin, methionine and zinc (each given individually, or as chelate -Zn-methionine). The aim of this study was to evaluate the influence of biotin or biotin + Zn-methionine additives on the health and performance of cows, in the first and second trimester of lactation.This study was carried out in 3 groups of cows, 30 animals in each group. In the first group cows were fed the usual fodder used on the farm. In the second group biotin at 10 mg/day/cow was added. In the third group both biotin at 10 mg/day/cow and Zn-methionine at 5 g/day/cow were added. The administration of biotin increased the milk yield and reduced the occurrence of retained placenta, as well as endometritis puerperalis. However, the high doses of biotin suppressed ovulation and oestrus symptoms in the investigated cows (low progesterone levels on days 15, 21 and 45 after calving). Zn-methionine in comparison to biotin had a lower effect on the milk yield in the cows. Moreover, its supplementation improved the milk content, as well as some of the blood parameters; it also decreased the number of somatic cells in milk. The concurrent administration of biotin and zinc-methionine seemed to be a good method for the prophylaxis of subacute mastitis and for the improvement of the high yielding dairy cows' productivity.

Effect of organic zinc supplementation on hematological, mineral, and metabolic profile in dairy cows in early lactation

“…The increasing trend of Zn concentration in S-group corresponds to increasing Zn-Met supplementation according to DM intake in early lactation. The other studies reported positive effect of organic Zn addition on Zn serum concentration (Kinal et al 2011, Sobhanirad et Naserian 2012, Dresler et al 2016. There were also significant changes in K, Mn, and P levels.…”

Assessment of the application for microelement methionine hydroxy analogue chelate replacing amino acid chelate in pregnant sows

“…Cu-MHAC even 50% Cu-, Zn-, Mn-MHAC substitution also signi cantly increased feed intake and weight gain of piglets, resulting in better muscle development [27,42]. In addition, Zn-MHAC improved milk production and signi cantly inhibited the in ammatory response of udder [43]. Methionine hydroxy analogue chelate (MHAC) may improve animal production performance due to its unique structural and chemical character.…”

Feed additives in the diet of high-producing dairy cows

“…According to Higuchi et al [2004], the beneficial effect of biotin on hoof health is due to an increase in the fat concentration in the hoof horn. Kinal et al [2011] demonstrated that supplementation of the diet of cows with 10 mg of biotin increased the amount of milk obtained (on average by 6.6 kg per day). The addition of biotin is particularly recommended for high-producing cows fed large amounts of concentrate feed, in which biotin synthesis in the rumen may be impaired, so that it is consumed by ruminal bacteria and does not reach the intestine [Tomlinson et al 2004].…”
