Assessment of feeding varying levels of Metabolizable energy and protein on performance of transition Murrah buffaloes

Abstract

Fifteen close up pregnant Murrah buffaloes of mean body weight (668.3 ± 24.03) kg, lactation number (2.8 ± 0.17) and expected producing ability (EPA) (2125.7 ± 46.34) were randomly distributed into three groups each of five animals to investigate the performance at different levels of metabolizable energy and protein. Control group was fed as per ICAR Nutrient requirements of animals (2013) recommendation whereas treatment group (1) high metabolizable energy and high metabolizable protein (HMEMP) and group (2) low metabolizable energy and low metabolizable protein (LMEMP) were offered with ration containing 15% more and 15% less ME and MP, respectively. The feeding trial was carried out for the period of 40 days before parturition and continued for 120 days after parturition. Intake of dry matter (DM) (%BW) was similar among experimental groups. Metabolizable energy (ME) (MJ/100 kg BW) and metabolizable protein (MP) (g/100 kg BW) intake was highest in HMEMP followed by control and LMEMP group, respectively. Digestibility trial of 7 days was conducted at 60 days post-partum and it was observed that apparent digestibility coefficients (%) of DM, organic matter (OM), crude protein (CP), ether extracts (EE), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were similar among the experimental groups. Milk yield (kg/kg DMI) was similar among treatment groups whereas 6% fat corrected milk (FCM) was lower in LMEMP group as compared to HMEMP and control. No significant effect of dietary MP and ME levels on milk composition was observed among experimental groups. There were no significant difference in non esterified fatty acid (NEFA), blood urea nitrogen(BUN), growth hormone (GH) and insulin like growth factor-1(IGF-1) concentration among different experimental groups whereas concentration of immunoglobulin G (IgG) (μg/ml) was found to be lower in LMEMP. The study results indicate that nutrient digestibility and lactation performance was not affected with 15% variation in intakes of ME and MP in lactating Murrah buffaloes.

Feeding Balanced Ration for Improving Dairy Cattle Productivity: A Review

“…Implementing balanced ration programs under small holding systems presents challenges, but large-scale implementation in tropical countries can lead to increased milk production, reduced methane emissions, nitrogen excretion into the environment, and lower feeding costs [19][20][21].…”

The Response of Different Planes of Nutrition and Analyzing its Effects on Nutrients Dynamics and Growth Rate in Ruminants: A Review

“…The digestibility of nutrients (DM, OM, CP, EE, CF, and NFE) was observed during the experiment, but the results showed no significant difference by feeding different sources of protein. Mustafa et al, (2017) (1980) made three rations which were isocaloric with three different CP levels 11.6%, 14.7% and 17.7% (low, medium and high). Rations made in this study were fed to thirty fattening steers (Zebu) by dividing animals equally into three treatments (n=10).…”

“…DMI (%BW) observed results showed a significant increase in G3 (2.29% ± 0.20) when compared to G2 (2.23 ± 0.02) and G1 (2.16% ± 0.02). Mustafa et al, (2017) evaluate the different levels of ME and MP in transition Murrah buffaloes with an expected producing ability (EPA) of 2125.7 ± 46.34. Fifteen animals were divided equally (n=5) into three groups.…”
