Strategic Supplementation with a High-Quality Feed Block on Roughage Intake, Milk Yield and Composition, and Economic Return in Lactating Dairy Cows

This study aimed to determine the effect of urea-calcium sulphate mixture (U-cas) levels in high-quality feed block (HQFB) on ruminal digestibility, fermentation and gas kinetics in rumen fluid of swamp buffalo by using in vitro techniques. The treatments were seven levels of U-cas incorporated in HQFB at 0, 3, 6, 9, 12, 15 and 18% and the experimental design was a completely randomized design. Gas production rate constants for the insoluble fraction, potential extent of gas and cumulative gas were linearly increased with increasing levels of U-cas in HQFB. The in vitro dry matter digestibility, in vitro organic matter digestibility, true digestibility and microbial mass were altered by treatments and were greatest at 18% U-cas supplementation. Concentrations of propionate were linearly increased with increasing levels of U-cas and was highest with U-cas supplementation at 18%. The NH3 -N concentration was highest when urea was added in the HQFB while NH3 -N concentration tended to be reduced with increasing level of U-cas. The findings suggest supplementation of 18% U-cas in HQFB improves kinetics of gas production, rumen fermentation, digestibility and microbial mass as well as controlling the rate of N degradation in the rumen of swamp buffalo.

“…Because of the poor quality of untreated rice straw, supplementation easily can increase milk production, as shown for supplementation with cottonseed meal (Wanapat et al, 1996); with an urea molasses-multi-nutrient block (Vu et al, 1999;Wanapat et al, 1999;Akter et al, 2004) and urea molasses treatment (Sheikh et al, 2014).…”

Paddy straw is a major agro-residue fed to ruminants in India. Feeding only rice straw does not provide enough nutrients to the ruminants even for maintenance due to the low nutritive value of this highly lignified material containing high concentration of anti-nutrition factors like lignin, silicates and oxalates. Despite the improvements of crop residues through various processing methods such as physical and chemical, the efficient utilization to desirable extent is still awaited. So utilization of paddy straw in association with concept of complete feed along with biological agents is need of the hour to maximize advantage from given feeds in animal production systems.

“…The increase in intakes of energy and nitrogen resulted in increase in milk yield. Wanapat et al (1999) observed that significant increase in milk yield of lactating dairy cows due to feeding of urea molasses mineral block (UMMB). Plaizier et al (1999) reported an increase in milk production by 4.5 L/d on supplementation of urea molasses blocks to dairy cows which were fed a basal diet of ad libitum grass hay and maize bran.…”

An experiment was conducted to assess the lactation performance and nutrient utilization of early lactating crossbred dairy cows fed with molasses based multi-nutrient liquid supplement (MMLS). A total of eighteen early lactating cows were divided into three groups (T1, T2 and T3) with six cows in each group following completely randomized design on the basis of body weight and milk production. Cows were fed concentrate mixture, green fodder and wheat straw to meet the nutrient requirement. The control group (T1) was fed basal diet without MMLS, whereas treatment groups (T2 and T3) were fed MMLS replacing 15 and 30% concentrate mixture, respectively. Feeding of MMLS did not show any significant change in average intake of dry matter (DM), organic matter (OM), crude protein (CP) and neutral detergent fiber (NDF) compared to control group. The ether extract (EE) intake of MMLS fed groups (T2 and T3) was lower (P<0.05) due to high EE content of concentrate mixture compared to MMLS. The acid detergent fiber (ADF) intake of T3 was higher (P<0.05) due to higher wheat straw intake. The digestibility of DM, OM, CP, EE, NDF and ADF were noted unchanged among all the three groups. The MMLS feeding did not show any significant change in milk yield of the animals when compared to control group. The findings of current study suggested that there was no adverse effect on intake and digestibility of nutrients and lactation performance due to feeding of MMLS to dairy cows while replacing up to 30% of concentrate mixture in diet.
