The Hematology of Lactating Buffalo Fed Local Foliage as Feed Supplement

Abstract

Abstract:The research aimed to determine the effect of feed supplements of cassava (Manihot esculenta Crantz) leaves, gliricidia (Gliricidia sepeum) leaves and katuk (Sauropus androgynus (L.) Merr.) leaves on the hematology of lactating buffalo. Four lactating buffaloes in Kanagarian Pamatang Panjang, Sijunjung district, West Sumatera, Indonesia were studied. The experiment used a Latin square design with four treatments and four replications/block. The treatments were control (without supplementary foliage, A), with cassava leaves (B), with gliricidia leaves (C) and with katuk leaves (D) each at 5 kg/head/day. The hematology variables measured were erythrocytes and leucocytes counts, as well as levels of hemoglobin and hematocrit. The results showed that supplementary foliage of 5 kg/head/day of cassava, gliricidia or katuk as leaves significantly increased the erythrocytes count and hemoglobin level, but did not affect the number of leucocytes in lactating buffalo.

Hematology and Milk Production of Murrah Buffaloes with Local Forage-Based Feeding in Kapau Village, Agam Regency, West Sumatra, Indonesia

“…This is caused by the higher percentage of administration of sweet potato leaves, cassava leaves, and USB with relatively high nutritional content, especially protein, Fe, and Cu minerals, resulting in increased erythrocyte levels. Roza et al (2015) stated that protein content, Fe, and Cu minerals are precursors in the formation of blood erythrocytes. The erythrocyte levels obtained were within the normal range, namely 5.30-7.90 x10 6 /µL (Diwyanto and Handiwirawan, 2006).…”

“…The erythrocyte levels obtained were within the normal range, namely 5.30-7.90 x10 6 /µL (Diwyanto and Handiwirawan, 2006). In addition, the content of amino acids and tannins in the given forage (cassava leaves and sweet potato leaves) can help microbial synthesis in the rumen, which will indirectly affect the formation of erythrocytes (Roza et al, 2015), where the content of condensed tannins in cassava leaves and sweet potato leaves can increase the supply of protein to the digestive tract (Wanapat, 2009). The condensed tannin content in foliage influences ruminant protein, leading to increased nutrition and red blood cell formation (Niezen et al, 1996), so erythrocyte levels can increase in the P4 treatment.…”

“…Hematological levels (erythrocytes, leukocytes, hemoglobin levels, hematocrit) can help farmers determine livestock's physiological condition. In the livestock's body, blood is essential in transporting oxygen, carbon dioxide, metabolites, hormones, feed nutrients, and immune system components (Roza et al, 2015). Feed is critical for increasing blood metabolism because it contains protein, vitamins, and minerals to form red blood cells.…”

Profil Fisiologis Pascapemberian Katuk Depolarisasi untuk Peningkatan Produktivitas Sapi Pedaging

“…Katuk depolarisasi memiliki pengaruh yang berbeda pada profil eritrosit dibandingkan daun katuk. Penambahan daun katuk dalam pakan mampu meningkatkan jumlah eritrosit, konsentrasi hemoglobin, dan hematokrit pada berbagai hewan, seperti kelinci (Akbar et al 2013;Satiyana et al 2021), tikus (Suparmi et al 2016), dan kerbau (Roza et al 2015). Pemberian ekstrak etanol daun katuk juga memberikan hasil serupa, yaitu peningkatan profil eritrosit pada tikus (Siswanto 2021).…”

“…Tidak terdapat perbedaan yang signifikan dalam jumlah leukosit antara kelompok yang mengkonsumsi katuk depolarisasi (P1 dan P2) dan kelompok kontrol yang tidak mengkonsumsi katuk depolarisasi (Gambar 2a). Penambahan daun katuk juga tidak memengaruhi jumlah leukosit pada kerbau laktasi (Roza et al 2015) dan kelinci (Akbar et al 2013). Uji coba pemberian katuk depolarisasi pada sapi perah laktasi juga tidak memengaruhi jumlah leukosit (Tarigan et al 2022).…”
