Nutrient Digestibility and Performances of Frisian Holstein Calves Fed with Pennisetum purpureum and Inoculated with Buffalo’s Rumen Bacteria

Abstract

Buffalo's rumen bacteria (BRB) are potential in digesting fiber feed. BRB already adapted well with low quality forages and agricultural byproducts. The aim of this study was to determine the effect of buffalo's rumen bacteria (BRB) consortium inoculated into preweaning Frisian Holstein calves on nutrient digestibility, physiological status, mineral uptake, and blood profile. This study used 14 isolates of bacteria isolated from rumen fluid of four local buffalos. The research units consisted of seven Frisian Holstein calves at two weeks old with the average body weight of 43.6±4.5 kg. Calves were inoculated with 20 mL of buffalo's rumen bacteria isolates [4.56 x 10 9 cfu/mL] every morning for 10 weeks. The calves were divided into two groups i.e., three calves received bacterial inoculation and four calves without any inoculation. The variables which were analyzed in the preweaning and weaning period were feed intake, digestibility, average daily gain (ADG), feed conversion ratio (FCR), rumen fermentation characteristics, body weight, physiological status, blood profile, and mineral status. Data were analyzed statistically using t-test. The results showed that inoculation of buffalo's rumen bacteria into Frisian Holstein calves effectively increased feed intake, characteristics of leukocytes and neutrophils, and cobalt (Co) uptake during the weaning period. Inoculation of rumen bacteria improved rumen pH during preweaning and weaning periods. Inoculation of rumen bacteria also had no negative effects on digestibility, feed conversion (FCR), average daily gain (ADG), and physiological status.Key words: buffalo rumen bacteria, digestibility, physiological status, blood profile, Pennisetum purpureum ABSTRAK Bakteri rumen kerbau (BRK) merupakan bakteri yang mempunyai potensi tinggi dalam pemanfaatan pakan sumber serat. Bakteri ini telah teradaptasi dengan baik terhadap pakan hijauan dan limbah pertanian yang berkualitas rendah. Inokulasi bakteri rumen kerbau pada pedet memungkinkan rumen berkembang lebih awal dan fermentasi di dalam rumen lebih optimal. Penelitian ini bertujuan untuk mengetahui efektivitas inokulasi bakteri asal rumen kerbau pada pedet Frisian pada kecernaan pakan, status fisiologis, serapan mineral, dan profil darah. Penelitian ini menggunakan 14 isolat bakteri yang berasal dari cairan rumen empat jenis kerbau lokal. Penelitian terdiri atas tujuh ekor pedet prasapih jenis Frisian Holstein berumur dua minggu dengan rataan bobot badan 43,6±4,5 kg. Rumen pedet diinokulasi 20 mL konsorsium bakteri dalam bentuk dadih setiap pagi hari selama 10 minggu dengan cara dicekok menggunakan spoit pada konsentrasi bakteri 4,56 x 10 9 cfu/mL. Tiga ekor pedet diberi inokulan bakteri dan empat ekor sebagai kontrol. Peubah yang dianalisis pada penelitian periode prasapih dan pascasapih antara lain konsumsi pakan, kecernaan, pertambahan bobot badan, konversi pakan, karakteristik fermentasi, bobot badan, status fisiologi, profil darah, dan status mineral. Data dianalisis menggunakan uji-t. Hasil penelitian men...

Effect of cellulolytic Ruminococcus albus KU-F152 and non-cellulolytic Selenomonas ruminantium S137 supplementation on feedlot performance, carcass characteristics and meat quality of Holstein crossbred steers

“…The cellulolytic R. albus KU-F152 and non-cellulolytic S. ruminantium S137 supplementation had no negative effects on the feed intake, final weight, weight gain and ADG of Holstein steers. Prihantoro et al [26] reported that the inoculation of ruminal bacterium increased the feed intake and ADG (19.47%) of Holstein calves during the weaning period. In the current study, R. albus and S. ruminantium inoculation increased the final weight, weight gain and ADG compared to the non-inoculated control by 4.46%, 16.45% and 16.13%, respectively.…”

“…These results were due to R. albus KU-F152 and S. ruminantium S137 increasing the feed digestion efficiency [5,27]. Similarly, Prihantoro et al [26] reported that buffalo rumen bacteria resulted in a relative improvement in the feed digestive efficiency of Holstein calves during the weaning period. In the current study, R. albus KU-F152 and S. ruminantium S137 increased the total VFA content in the rumen fluid.…”

“…Furthermore, the inoculation or supplementation of rumen bacteria in rearing cattle may increase performance, such as feed intake, feed conversion and body weight [11,15]. While the inoculation of rumen bacteria could increase the feed intake of Holstein caves during the weaning period [26], few studies have reported the effect of inoculation of rumen bacteria on performance. However, there has been no report on bacterial application in feedlot Holstein steers.…”
