Feeding Moringa oleifera fresh or ensiled to dairy cows—effects on milk yield and milk flavor

Abstract

Moringa oleifera, either fresh or ensiled, was compared with Elephant grass as a main feedstuff for dairy cows. To test the effects feed had on milk yield, milk composition, ration digestibility, and the organoleptic characteristics of milk, six lactating dairy cows were used in a Changeover 3 × 3 Latin Square experiment, replicated twice. With equal intake of metabolizable energy the intake of protein and fiber differed (p < 0.001) between all diets where fresh Moringa had the highest and the Elephant grass diet had the lowest intake. Compared with the control diet, ensiled Moringa had higher digestibility (P < 0.05) of both protein and fiber. With the exception of DM digestibility, no digestibility differences were found between fresh Moringa and Moringa silage treatments. Milk yield did not differ between any of the treatments and averaged 13.7 kg cow day(-1). Milk composition was similar among all treatments. Milk from the fresh Moringa treatment, however, had a grassy flavor and aroma, significantly different from the other two treatments, even though it was normal in color and appearance. No organoleptic differences were found between milk from the control treatment and the Moringa silage treatment. The conclusion is that Moringa silage can be fed to dairy cows in large quantities to produce the same quantity and quality of milk as traditional diets.

DEGRADABILIDAD RUMINAL DEL FOLLAJE DE Moringa oleifera A TRES DIFERENTES EDADES DE REBROTE

“…Esto puede ser explicado porque el contenido de nitrógeno en las hojas y tallos jóvenes generalmente no disminuye significativamente cuando la madurez de la planta incrementa en rangos de edades muy cortas (Miquilena et al, 1995). En el presente trabajo el contenido de PB estuvo entre el rango de 170-274 g PB kg -1 MS, reportado por otros autores (Reyes-Sánchez et al, 2006a;Reyes-Sánchez et al, 2006b;Reyes-Sánchez et al, 2009;Mendieta-Araica et al, 2011;Mendieta -Araica et al, 2013) No obstante, el contendido de FDN, FDA y cenizas incrementan ligeramente cuando se incrementa la edad de rebrote. Los tallos jóvenes son normalmente de alta calidad, sin embargo, la calidad disminuye más rápido que en las hojas, debido a que la pared celular y el contenido de lignina aumentan al incrementar la edad de rebrote.…”

“…Los tallos jóvenes son normalmente de alta calidad, sin embargo, la calidad disminuye más rápido que en las hojas, debido a que la pared celular y el contenido de lignina aumentan al incrementar la edad de rebrote. El contenido de FDN y FDA obtenidos en este estudio para diferentes edades de rebrote están dentro del rango de 219-564 g kg -1 MS y 114-515 reportados por otros investigadores (Makkar and Becker 1996;Makkar and Becker 1997;Reyes-Sánchez et al, 2006;Reyes-Sánchez et al, 2009;Mendieta-Araica et al, 2011;Mendieta-Araica et al, 2013) para FDN y FDA, respectivamente.…”

“…Moringa oleifera es uno de estos árboles forrajeros que crece bien en todo tipo de suelos desde ácidos hasta alcalinos (Duke, 1983), su producción de forraje es entre 24 y 99 ton MS/ha/año, las hojas frescas contienen entre 17 y 27.4% de PB, 2.73 Mcal de EM/kg MS (Reyes-Sánchez et al, 2006;Reyes-Sánchez et al, 2006b;Reyes-Sánchez et al, 2009;Mendieta-Araica et al, 2011;Mendieta -Araica et al, 2013) y son ricas en vitaminas A, B y C, calcio, hierro y en aminoácidos esenciales.…”

Effects of feeding a Moringa oleifera rachis and twig preparation to dairy cows on their milk production and fatty acid composition, and plasma antioxidants

“…Lactose and protein concentrations in milk were not affected by including moringa in their feed, probably because the basal diet provided adequate levels of fibre and protein. 24 Conversely, Mendieta-Araica et al 6 reported a decrease in milk yield without an effect on milk composition when soybean meal was replaced with a moringa leaf preparation in dairy cow feed, which probably correlated with increases in protein and energy intake in the soybean meal concentrate. Kholif et al 8 found that the milk lactose content significantly increased, but the milk-fat and protein concentrations were unaffected when a moringa leaf supplement was included in the feed of lactating goats.…”

IMPACT OF SUBSTITUTING SOYA BEAN MEAL BY MORINGA (Moringa oleifera) LEAVES MEAL IN THE DIET ON GROWTH PERFORMANCE, NUTRIENTS DIGESTIBILITY, BLOOD CONSTITUENTS AND CARCASS TRAITS OF GROWING RABBITS.

“…Recently, the interest has been increased towards the utilization of moringa (Moringa oleifera) leaves meal as a good protein source in the diets of farm animals as asubstitutefor the traditional protein sources such as soya bean, sunflower and ground nut meals (Sarwatt et al, 2002;Asaolu et al, 2009;Fadiyimu et al, 2010;Mendieta-Araica et al, 2011;El Tazi, 2014;Melesse et al, 2011 andGhomsi et al, 2017) in order to decrease the feeding costs. Sarwatt et al, (2004) reported that moringa foliage is a potential inexpensive protein source for livestock feeding.…”
