Comparison of oil and fat supplementation on lactation performance of Nili Ravi buffaloes

Abstract

The effects of feeding rumen-inert fat sources on production responses of lactating dairy cows have been well reported but less thoroughly described in lactating dairy buffalo. The objective of this study was to investigate the effect of oil and 2 different rumen-inert fat sources on dry matter intake, milk yield, milk composition, and milk fatty acid (FA) profile in Nili Ravi buffalo. Twelve multiparous mid-lactating Nili Ravi buffaloes received 4 treatments in a 4 × 4 Latin square design with a period length of 21 d. The treatments were (1) the basal diet without supplementation of oil or fats (CTRL), (2) the basal diet supplemented with canola oil (CO), (3) the basal diet supplemented with calcium salts of palm FA (Ca-FA), and (4) the basal diet supplemented with high palmitic acid (PA). Dry matter intake was decreased by 4.4% in the CO compared with Ca-FA and PA. Milk yield and milk fat yield were increased by 7.8 and 14.3%, respectively, in CO, Ca-FA, and PA compared with the CTRL. Milk fat content increased by 7.5%, whereas milk fat yield tended to increase with the supplementation of Ca-FA and PA compared with CO. No effect on milk yield and milk composition was observed in Ca-FA versus PA treatments. The yield of medium-chain FA was increased by Ca-FA and PA versus CO. The CO treatment increased the yield of long-chain FA compared with Ca-FA and PA treatments. Plasma glucose level was higher in CO, Ca-FA, and PA compared with the CTRL. In conclusion, feeding rumen-inert fats in the lactating buffalo diet proved to be a useful strategy to increase the 3.5% fat-corrected milk yield due to the higher milk fat content in this study.

A Mixed Phytogenic Modulates the Rumen Bacteria Composition and Milk Fatty Acid Profile of Water Buffaloes

“…The major milk fatty acids were C16:0 and C18:1, followed by C18:0 and C14:0, which is in agreement with earlier studies in dairy cattle (70,71). Contents of SFA (65%) and UFA (35%) measured in our study are similar to earlier reports in cattle and buffaloes (72,73).…”

Effect of Graded Supplementation of Calcium Salts of Palm Fatty Acids on Lactation Performance of Nili Ravi Buffaloes

“…Likewise, a study conducted in lactating buffalo by feeding 300 g/d of Ca-PFA observed an increase of 22% in milk yield (Polidori et al, 1997). Recently, our research group investigated the effects of feeding Ca-PFA in lactating buffalo and observed an increased milk yield by 7.85% and milk fat yield by 14.3% (Hifzulrahman et al, 2019). Nevertheless, high levels of feeding Ca-FA could decrease the DMI (Schauf and Clark, 1992;Rabiee et al, 2012) and consequently the milk yield (Schauf and Clark, 1992).…”

“…Milk production from morning and evening milking were pooled daily and analyzed by Gerber method for milk fat content (IDF, 1981). An aliquot of milk from day 21 of each period was stored at −20°C without preservative until analyzed for FA profile as described by Hifzulrahman et al (2019). Samples from all the buffaloes were collected on 3 rd last day of each period in heparinized syringes and immediately centrifuged at 2,000 × g for 15 min at 4°C.…”

“…Samples from all the buffaloes were collected on 3 rd last day of each period in heparinized syringes and immediately centrifuged at 2,000 × g for 15 min at 4°C. Plasma was separated, aliquoted, and stored at −20°C to be assayed by enzymatic method as described by Hifzulrahman et al (2019).…”

Determination and phylogenetic analysis of the complete mitochondrial genome of Bubalus bubalis Linnaeus, 1758 breed Nili-Ravi (Artiodactyla: Bovidae)

“…Nili-Ravi buffaloes (Bubalus bubalis Linnaeus, 1758 breed Nili-Ravi, NRB) are characterized as a tropical/subtropical breed with crude feed tolerance and excellent milk production performance (Hifzulrahman et al 2019). In this study, we newly determined the complete mitochondrial genome of NRB, and the adult individuals of NRB were collected at its culturing farm in Nanning city (22 90 0 29.27 00 N and 108 36 0 07.38 00 E), Guangxi Zhuang Nationality Autonomous Region, China on May 2019.…”
