“…Guinea fowls accumulated less abdominal fat than chickens in the study since they are characterized by having lean meat. CAB International (1987) stated that guinea fowl meat has a low fat content of 4% as compared to chickens, beef (21%), lamb (25%) and pork (21%), which makes it appealing to health-conscious consumers in addition to it being white meat (Nahashon et al 2006). High weights of liver in the chickens are related to the high abdominal fat content and make animals prone to metabolic disorders such as fatty liver diseases and sudden death in all types of animals including chickens (Skřivan et al 2000).…”

The objective of the study was to determine the effect of age and sex on carcass characteristics and internal organ weights in scavenging guinea fowls and chickens. Ninety-six scavenging birds, purchased from farmers, were used comprising 48 guinea fowls and 48 chickens from communal farmers. Guinea fowls comprised 25 females and 23 males, with 21 growers and 27 adults. Chickens had 18 females and 30 males with 19 growers and 29 adults. Guinea fowls had heavier body weight and relative hot carcass and cold dressed weight than chickens and which increased with age. Breast and wing relative weights were higher in guinea fowls. Chickens recorded the higher weight of leg and drumstick than guinea fowls. The neck, feet and head weights were heavier in chickens except for the back which was similar to guinea fowls. Chickens had significantly higher abdominal fat than guinea fowls. Relative weights of the heart, liver, kidney, lung and gizzard were higher in chickens. Relative total intestinal weight and lengths of total intestines, small and large intestines were higher in chickens than in guinea fowls. Relative lengths of the intestines decreased with age. Chickens and guinea fowls could have different capacities to utilize scavengeable feed resources.

“…Some recommendations regarding dietary ME concentrations in slow-growing chickens and their effect on BWG are described in the literature Nahashon et al (2006). reported 3100 kcal ME/kg DM;Raju et al (2004) andLi et al (2013) mentioned 2900 kcal ME/kg DM andHaunshi et al (2012) found that 2800 kcal ME/kg DM was sufficient to maximise the BWG.…”

<p>The objective of the current study was to estimate the requirement of metabolizable energy (ME) and crude protein (CP) for growing Rhode Island Red male chickens from 17 to 119 days-old, under tropical conditions of Yucatan, Mexico. The experiment consisted in three feeding phases (17–56, 57–91, 92–119 days old), using a factorial 2x3 design for each one. Two constant ME (2900 and 3100 kcal/kg DM), and three CP concentrations (% DM) that varied with age: 22, 20 and 18% (17–56 days-old); 20, 18 and 16% (57–91 days-old); and 18, 16 and 14% (92–119 days-old) were used. Two batches of 72 Rhode Island Red male chickens each one was used; the first one for the first feeding phase and the second batch for the second and third feeding phases. Response surface procedures to obtain the best ME and CP concentrations were carried out. The body weight gain (BWG) and feed intake (FI) were greater in the first feeding phase with 2900 kcal ME/kg DM in the diet; however, in the second phase there was not significant effect of energy concentration. From 17–91 days-old, the FI increased with 2900 kcal ME/kg DM in the diet. Chickens had a higher BWG from 92–119 days-old when 16% CP was included in the diet. Protein efficiency was better from 17–119 days-old when the lower CP concentration was included in the diet. In conclusion, the greatest BWG were obtained, when 2900 kcal ME/kg DM, for the three feeding phases, was used. The best approximations of CP requirement in the diet for the first, second and third feeding phases were 21.3%, 19.2% and 17.1%, respectively.</p>

The objective of this study was to investigate the effect of feeding varying levels of Phane meal (Imbrasia belina) as a protein source on growth performance and carcass characteristics of guinea fowl reared under intensive system up to 13 weeks of age. A total of 96 day old keets were randomly allocated to 4 treatment diets, which were replicated 4 times (n=6/replicate). The inclusion levels of Phane meal in the diets were 4.5%, 9% and 13.5%. Control diet contained 3% fishmeal. Keets were fed 24% CP guinea fowl starter diet from day 1 to 6 weeks and 17% CP guinea fowl finisher from 7 to 13 weeks of age. Feed and water were provided ad libitum. Birds were vent sexed at 8 weeks of age. Parameters measured were FI, average daily gain (ADG), body weight (BW), carcass dressed weight, dressing percentage and feed conversion ratio (FCR). Keets were slaughtered at 13 weeks of age and carcass dressed weight and dressing percentage determined. The present results showed that FI and BW increased significantly (p<0.05) with age. Dietary treatment had no influence on FI. Although ADG and FCR did not differ among treatments, guinea fowl on control diet tended to have higher ADG (0.0138±0.0003 kg) and lower FCR (3.98). Dressing percentage was not affected by dietary treatment; however, birds on control and 4.5% Phane diets tended have higher values compared to other treatments. Also, final live weight and dressing percentage of females and males were not significantly (P>0.05) different. These results suggested that Phane meal can be included in guinea fowl diets up to 4.5% without affecting growth.
