Nutrient Utilization and Milk Yield of Dairy Cows Fed a Diet Containing Monensin, Garlic Peel and Organic Minerals During the Lactation Period

Abstract

The objective of this research was to determine nutrient intake, nutrient digestibility, milk yield, and milk quality of dairy cows that consumed feed supplemented with monensin, garlic peel (Allium sativum), and organic minerals. Twenty-one Friesian Holstein dairy cows with 644±72 kg body weight received dietary treatments consisting of: T0: basal feed + 0.3 g/d monensin;T1: basal feed + 30 ppm garlic-peel powder; and T2: basal feed + 30 ppm garlic peel powder + organic minerals (1.5 ppm Cr, 0.3 ppm Se, and 40 ppm Zn-lysinate). Allocation of dietary treatments followed a completely randomized design with seven replicates per treatment. Results showed that supplementation with monensin, garlic peel, and organic mineral did not significantly affect nutrient intake (DM, OM, CF, CP, NDF, ADF, TDN), nutrient digestibility (DM, OM, CF, NDF, ADF, TDN), milk yield, or milk quality. However, treatment significantly decreased crude protein digestibility (P<0.01). The conclusion was that supplementation with garlic peel can replace monensin in feed for dairy cattle.

Performance of Dairy Cows in Late Lactation Period Recieving Heit Chrose Feed Suplement

“…The addition of Heit-Chrose feed supplements showed a significant effect on the digestibility of dry matter and organic matter, this is thought to be the presence of saponins and allisins in Heit-Chrose. Saponins as defaunation agents are able to suppress the growth of rumen protozoa optimally, while allisin compounds are able to suppress methanogenic populations [4].…”

“…The Heit-Chrose is one of feed supplement products derived from garlic extract which contains allisin, saponins and organic minerals (Se, Cr and Zn). Saponins and allicins contained in Heit-Chrose are able to increase propionate production and reduce methane gas production which is a result of carbohydrate fermentation [4]. The addition of Cr can increase the use of glucose in the body, while the Se given in feed will be able to cell protected of oxidative damage during metabolism and Zn-lysinant will increase metabolism proces.…”

“…60 ± 3.86 𝑎 66.15 ± 1,77 𝑏 DMD : Digestibility of dry matter, OMD : organic matter of digestibilityThe average of feed intake of group A was 13.56 ± 1.61 kg and the average DM consumption of group B was 11.75 ± 1.22 kg. the DM needs of the lactation group A quality of feed ingredients[4,5], it is further explained that, one of the factors affecting consumption is the quality of feed, good quality feed has a relatively high level of consumption compared to quality feed low. From the three treatments, it showed that the consumption of DM in A and B in repetitions of R0, R1 and R2 decreased, in repetitions DOI 10.18502/kls.v0i0.11822 ICASI of R0 the consumption of DM was 12.95 kg in replications R1 the consumption of DM was 12.74 kg and in tests R2 consumption of DM was 12.67 kg.…”
