<b>Feeding behavior of lactating cows fed palm kernel cake in the diet

Abstract

This study aimed to evaluate the effect of including of palm kernel cake on feeding behavior of lactating crossbred cows. Twelve crossbred Holstein x Zebu cows were distributed in three 4 x 4 latin squares, with the following treatments: control; inclusion of 5%; inclusion of 10%; inclusion of 15% palm kernel cake in the diet dry matter. The animals were observed during four periods as to feeding behavior, 24 hours in each period. There was no effect of inclusion of palm kernel cake (p > 0.05) on time spent on eating, ruminating and idling. The feeding efficiencies of dry matter and corrected neutral detergent fiber, total digestible nutrients, and the rumination efficiency of corrected neutral detergent fiber were not influenced (p > 0.05). There was a linear increase with the inclusion of palm kernel cake (p < 0.05) for the efficiencies of rumination of dry matter and total digestible nutrients. The number of periods and duration of behavioral activities was not affected (p > 0.05). The inclusion of palm kernel cake in diets for dairy cows causes no change in behavior activities and efficiencies of feeding and rumination, until the 15% level of inclusion.

Effects of palm kernel cake (Elaeis guineensis) on intake, digestibility, performance, ingestive behaviour and carcass traits in Nellore bulls

“…There was a decrease in eating and rumination rates, which was associated with the reduction of DMI caused by increases in the ADF and ADL contents of the diets, which stimulated rumination activity (Huhtanen et al ., 2016); however, these conditions limited intake due to a longer retention time of feed in the rumen (Van Soest, 1994), as observed in other studies involving palm kernel cake (Pimentel et al ., 2015; Santos et al ., 2016).…”

“…The diversity of favourable soils and a suitable climate for the cultivation of oil palm increases the availability of its residues throughout the year mainly in arid regions (Gonzaga et al, 2015;Lima et al, 2015;Oliveira et al, 2015aOliveira et al, , 2015b. These residues can potentially be used in animal feed because of the chemical composition of the cakes (Ferreira et al, 2012;Silva et al, 2013;Abubakr et al, 2015;Pimentel et al, 2015). However, the high lipid content (ether extract-EE, 110 g/kg) along with the low-quality fibre content (acid detergent fibre-ADF, 421 g/kg) of palm kernel cake can decrease animal intake and reduce digestibility and performance due to interference with fibre digestion or diet palatability (Sanders et al, 2015;Santana Filho et al, 2015).…”

“…Crude protein digestibility depends on the source and protection of the protein source [ 30 ]. The low digestibility of nitrogen-free extract and total digestible nutrient value was related to crude fiber content [ 31 ].…”
