Performance of growing pigs fed diets based on by-products of maize and wheat processing

Abstract

Forty-eight crossbred Landrace × Large white pigs with an average body weight of 8.5 ± 0.4 kg and aged 2 months were used to evaluate performance and carcass characteristics of pigs fed two diets in which bran from maize or wheat was used as the energy source. A third diet based on whole maize grain was used as a control. Animals in groups of four, balanced for litter, sex and weight were allotted to dietary treatments in a completely randomised design with four replications. Data were collected on feed intake and weight gain for a period of 4 months. A digestibility trial was carried at the end of the feeding trial using two male pigs per treatment while six pigs per treatment were randomly selected for slaughter to determine carcass characteristics. Daily gain averaged 0.23, 0.31 and 0.13 kg/day, for pigs fed maize bran, wheat bran and whole maize diets, respectively. Average feed intake and final body weight were significantly (P < 0.05) affected by diets. Digestibility of dry matter, crude fibre and calcium were higher (P < 0.05) for pigs fed maize bran while crude protein digestibility was highest (P < 0.05) for the pigs fed wheat bran. There were significant differences (P < 0.05) between the diets in carcass yield, ham, head, trotters and heart weights and also for rib weight, rib eye muscle and other tissues. This study indicates that comparable performance of growing pigs fed cereal bran and full-grain diets are real.

Growth Performance, Nutrient Digestibility and Carcass Characteristics of Pigs Fed Diets Containing Amarula (Sclerocarya Birrea A. Rich) Nut Cake as Replacement To Soybean Meal

“…Wang et al (2016) demonstrated that high residual oil in diets negatively impacts nutrient digestion and absorption, which was apparent in this study with pigs fed diets that contained high levels of ANC. The higher bre digestibility observed for pigs fed diets containing higher levels of ANC (Table 7) could have resulted from fermentation of the bre in the hind gut with the volatile fatty acids (VFAs) produced, contributing to the net energy requirements of the pigs (Mwesigwa et al 2013).…”

Effect of Fermented Kepok Banana Corm Inclusion in the Diet on the Nutrient Digestibility and Mineral Ca and P Retention of Growing Pigs

“…Mwesigwa et al [20] stated that feed sources helped influence feed intake. Total feed intake can also be influenced by the concentration of energy, palatability, nutritional content, breed and growth rate [21][22][23].…”

“…The achievement of study was in line with [34] Rideout et al, (2008) stated that source of starch may influence digestibility of mineral Ca and P in growing pigs at 30 kg body weight. Mineral Ca absorption was affected by the balance of Ca and P in the diet [21,34].…”

Effects of Substituting Taro (Colocasia esculenta) Wastes Silage in Diets on Growth and Nutrient Digestibility In Pigs

“…The by-products of taro cultivation are leaves, petioles, and peel (a waste discarded from taro planting by farmers and taro processing factories). The above by-products are good energy sources for livestock, and with the appropriate preservation practices, these by-products could be beneficial to the livestock farming community and relieve the pressure of competition for food between humans and animals (Mwesigwa et al, 2013).…”
