Effect of bypass fat supplementation on productive performance and blood biochemical profile in lactating Murrah (Bubalus bubalis) buffaloes

Abstract

The study investigated the effect of dietary supplementation of bypass fat on productive performance and blood biochemical profile of lactating Murrah buffaloes (Bubalus bubalis). Fifteen multiparous buffaloes (2-4 lactation) of early to mid lactation were divided in three homogenous groups T(1) (control), T(2), and T(3) of five each. The animals in T(1) were fed with a basal diet consisting of a concentrate mixture, green sorghum, and wheat straw as per requirements, while the animals in group T(2) and T(3) were fed with same ration supplemented with 0.7 % (100 g/day) and 1.4 % (200 g/day) bypass fat (on dry matter intake (DMI) basis), respectively. The feed intake, milk yield, and milk composition were not influenced by supplemental bypass fat. However, fat-corrected milk (6.5 %) yield was higher (P < 0.05) in T(3) (14.21) than that of T(1) (9.83) and similar with T(2) (11.05). Feed efficiency (milk yield/kg DMI) was higher (P < 0.05) in group T(3) (0.51) than that of T(1) (0.38) and T(2) (0.41) indicating that buffaloes fed with bypass fat which is 1.4 % (200 g/day) of the diet were economically more efficient. The serum cholesterol level was higher (P < 0.01) in bypass fat-supplemented group (T(2) and T(3)) of animals. Serum high density lipoprotein (HDL) cholesterol (good cholesterol) level was more (P < 0.05) than LDL cholesterol (bad cholesterol) level with higher dose of bypass fat in T(3) than T(2). It was concluded that bypass fat supplementation with 1.4 % of the diet (200 g/day) increased the fat-corrected milk production and feed efficiency along with serum HDL cholesterol level in lactating Murrah buffaloes.

Effect of peripartum nutritional supplementation on postpartum fertility and blood biochemical and steroid hormone profile in crossbred cows

“…The overall mean plasma total cholesterol value in the cows supplemented was observed to be significantly higher (p<0.01) as compared to control group which was substantiated by the observations of Tyagi et al (2010) and Ranjan et al (2012). Dietary fat increases circulating concentrations of cholesterol (Staples and Thatcher, 2005) and progesterone and the lifespan of induced CL in cattle.…”

Effect of Feeding of Bypass Fat Mineral Mixture on Productive Performance and Quality of Milk of Buffaloes in Armori Tahsil

“…It was noticed that average weekly milk yield showed that Bypass fat supplementation at 1.4% of DMI (200 g day -1 ) increased the milk production and feed efficiency in lactating Murrah buffaloes (Ranjan et al, 2012). There was an improvement of 6.02% in milk yield of early lactating crossbred cows fed 75 g day -1 per animal PF (Rajesh, 2013).…”

Adição de óleo de palma na dieta sobre a lipidemia e a qualidade do sêmen de bubalinos (Bubalus bubalis)

“…Para os ácidos graxos saturados, a elevação de consumo foi de 71,23% nos animais tratados (132,07 versus 77,14g/animal/dia). Gandra et al (2011) (6,56mg/dL) e Ranjan et al (2012) (16,27mg/dL), estes últimos tendo fornecido gordura protegida para fêmeas bubalinas em lactação. A presença de receptores para VLDL em espermatozoides sugere que estes utilizam lipídios extracelulares, estando o papel desses receptores associado ao prolongamento da utilização de energia e ao provimento para o espermatozoide de metabólitos essenciais, tais como triglicérides, fosfolípides e ácidos graxos (Argov et al, 2007), com maior eficiência na utilização de energia.…”

“…Entretanto, os dados observados foram distintos dos previamente publicados para touros bubalinos, de 213,26 mg/dL e 324,74±3,81mg/dL (Ranjan et al, 2012;Nalavade et al, 2002). Sob esse prisma, incrementos nos lipídios séricos totais, caso associados a um aumento paralelo nas concentrações de lipídios totais no plasma seminal, como ocorre em bovinos (Beer-Ljubic et al, 2009), poderiam representar uma ameaça à integridade da membrana espermática.…”

“…O aumento das concentrações lipídicas na dieta de ruminantes pode ocasionar elevação nos parâmetros séricos de colesterol, triglicerídeos, lipoproteínas de alta densidade (HDL), lipoproteínas de baixa densidade (LDL), lipoproteínas de muito baixa densidade (VLDL) e lipídios totais (Ranjan et al, 2012). Sabe-se, porém, que, quando os bubalinos são criados sob diferentes condições ambientais e de manejo, variações podem ocorrer, tornando os parâmetros séricos relatados na literatura inconsistentes para generalizações (Nalavade et al, 2002;Nikam et al, 2005).…”
