Different Levels

summaryGrowth and visceral organ weights of male guinea fowl (Numida meleagris) given different levels of oxytetracycline have been studied in two experiments. In the first experiment 0, 5·0, 10·0, 15·0 and 20·0 mg oxytetracycline per kg diet were given to male guinea fowl from day 1 to 12 weeks. Body weight showed significant (P < 0·05) increases with incremental levels of the antibiotic up to 10 mg/kg diet. No further increases in growth were recorded with supplementation above this level. There were no treatment effects on the gizzard, lungs and male reproductive organs. Only the heart, liver and intestine weights were significantly (P < 0·05) affected by the treatment, and then only at the highest (20 mg/kg) of the inclusion rates examined. A second experiment was conducted to find out if the growth response obtained with 10 mg/kg oxytetracycline could be produced with a smaller dose. This was achieved at 6·6 mg/kg.

The effect of feeding recommended levels of three antibiotics on the visceral organs of growing guinea fowls has been examined. Day old broiler type guinea fowls were given Oxytetracycline, Rocaryone, and zinc bacitracin supplemented diet till 12 weeks of age. Dressed weight of medicated guineas were significantly higher than controls. No treatment effects were observed on the lungs, gizzards and reproductive organs. Fat pads were significantly (P.05) heavier in treated birds as compared with controls. Heart and liver weights were also significantly higher (P.05) in treated guinea fowls.

Pathogenic Effects

SummaryEimeria grenieri was isolated from intensively reared guinea fowl in Britain. The oocysts had average dimensions of 21·09 × 15·48 μm and a small micropyle. Three generations of schizonts were found in the small intestine. The first mature schizonts were found in the upper intestine 30 h after inoculation. Second-generation schizonts were seen 48–80 h and third-generation schizonts were present 80–96 h after inoculation. These schizonts were found in the middle and lower small intestine. It was confirmed that gametogony of this species occurs only in the caeca. The pre-patent time was 112 h and the reproductive index from a dose of 6 × 102 oocysts was 8 × 104. Doses of between 1 × 104 and 1 × 106 caused severe depression of body weight gain. Immunity to re-infection developed rapidly. Sulphaquinoxaline at a dose of 0·04% in the drinking water given after inoculation was effective in reducing the pathogenic effects of the disease. Robenidine given in the food at a concentration of 16·5 ppm (50% of the recommended concentration for chickens) was effective in preventing disease caused by E. grenieri.The endogenous life-cycle of E. grenieri was completed in the chorioallantoic membrane of developing chicken embryos.

Abstract The objective of this study was to investigate the effect of genotype and sex on the degree of maturity of the plumage of guinea fowl. The experimental materials comprised 300 slow-growing (Label group) and 300 fast-growing (Standard group) gray guinea fowl. At 12, 14 and 16 weeks of age, 12 birds from each group (six ♂ and six ♀) were slaughtered. Dry feathers were collected from the dorsal area on both sides of the spine, in the interscapular and thoracic region, and from the outer side of the left thigh. The percentages of feathers at five stages of development were determined for each bird: I - pinfeathers covered in sheaths, II - beginning of vane development, III - feathers unsheathed by half of rachis length, IV - feathers unsheathed by more than half of rachis length, V - fully developed vanes and afterfeathers. Feather weight was determined and expressed as a percentage of a bird’s total body weight. At 12 weeks of age, guinea fowl were characterized by the lowest (68.23%) percentage of mature feathers. The percentage of mature feathers increased to 79.36% in week 14 and to 83.20% in week 16. In weeks 14 and 16, the proportion of feather weight in total body weight was significantly lower (9.95 and 10.20%, respectively) than in week 12 (11.88%). Genotype had no effect on feather development, but it influenced feather weight and percentage. Significant (P<0.05) genotype × sex × age interactions were observed in percentage of stage I feathers. Label group guinea fowl were characterized by higher feather weight and a higher proportion of feathers in total body weight than Standard group guinea fowl (267.0 g and 11.01%, 248.9 g and 10.34%, respectively). The percentage of feather weight was lower in females than in males.

Significant Difference

This study was conducted to investigate the effect of dietary crude protein (CP) on growth and laying performance of indigenous Guinea fowls (Numida meleagris) in Ghana. A total of Sixty (60) grower pearl Guinea fowl made up of twelve (12) males and forty-eight (48) females were randomly selected and grouped into four made up of (4) females and one (1) male. The groups were each subjected to four experimental diets containing 16%, 18%, 20% and 22% crude protein (CP). A completely randomized design (CRD) was used for the experiment. The data collected were subjected to analysis of variance (ANOVA) using GenStat version 11.1 (2008). Least significant difference (LSD) at 5% was used to separate the means. The result showed that birds fed with diets containing 22% crude protein (CP) had the heaviest (P= .05) body weight and body weight gain and reached age at first egg earlier followed by birds fed with diets containing 18% CP, 20% CP and 16% CP respectively. Feed consumption increased with an increase in dietary crude protein. Body weight at first egg was highest (P= .05) among birds fed with diets containing 22% crude protein (CP) and lowest in 16% crude protein (CP). Birds fed with diets containing 20% and 22% crude protein (CP) had the highest (P= .05) hen-day and hen- house egg production, whiles 16% crude protein (CP) diet recorded the lowest. It was concluded that body weight, body weight gain and total feed intake of indigenous Guinea fowls increased with increasing dietary crude protein. It is recommended to farmers that, diets containing 22% crude protein (CP) is ideal for optimum productivity of indigenous Guinea fowls.

In a study that lasted for 120 days, 20 weaned Yankasa ram lambs aged 6 months and weighing between 10.5 and 14.5kg with an average of 12.75kg were offered a basal Digitaria smutsii hay diet at 2% of body weight. This was supplemented with a concentrate mixture made to supply 14.6% crude protein and 2.6 Mcal ME per kg and offered to treatment groups A, B, C and D at 1, 2, 3, and 4% of body weight respectively. There were five replicates and the animals were fed individually. Results indicated that the differences in Average Daily Gain was significant (P<0.05) between all the treatments; the value increased with increased level of feeding. The cost of effecting one unit of live weight increase was not significantly different (P<0.05) between treatments, A, B, and C, but it was significantly lower (P<0.05) than for treatment D. The low growth response of lambs fed the concentrate at 1% of body weight and the higher cost per unit gain of lambs offered the supplement at 4% of body weight suggested that concentrate supplementation at 2 and 3% of body weight was adequate for optimum liveweight gains in the Yankasa sheep breed.

The physical characteristics of 338 indigenous helmeted guinea fowls at 28 and 52 weeks of age were described. Four main colour types or varieties recognised were Ash (Lavender), Black, Pearl (Grey) and pure White. Body weights averaged 1.15 ± 0.03kg and 1.34 ± 0.05kg at 28 and 52 weeks of age respectively for the guinea cocks and 1.07 æ 0.04kg and 1.29 æ 0.06kg at 28 and 52 weeks respectively for the guinea hens. The overall mean body weight for the entire population was 1.1 ± 0.4kg at 28 weeks of age and 1.31 ± 0.07kg at 52 weeks of age. Body weights were significantly (P<.05) bigger at end of laying (52 weeks) than at pointof lay. The males at each age and in each variety also had larger body weights than the females. The guinea cocks had slightly longer body (43.1 vs 42.6cm), keel (14.8 vs 14.4cm), wing (20.3 vs 20.2cm), shank (8.4 vs 7.9cm), drum stick (13.1vs 12.4cm), thigh (9.9 vs 9.6cm), toes and claws, wattle (3.0 vs 2.6cm), jhelmet (3.7 vs 3.2cm), beak (2.7 vs 2.5cm) and larger body girth (30.3 vs 29.4cm) than the guinea hens. About 21.14 and 24.16% of the neck of the males and females respectively were devoid of feathers. Colour of the naked portion of the neck was bluish-black and bear long hair like filoplumes on the dorsalregion. The colour of the beak was light brown in all the birds. All the Black and White birds had light brown shanks while 28.9 and 37.5% of the Ash and Pearl birds, respectively had partly brown and partly grey shank. 62.5 and 28.6% of the Pearl and Ash birds respectively, had brown shanks while 42.6% of the Ash birds had grey shank. The colour of the wattle was red in all the birds. The great variation in the various parameters measured and weighed suggests that they can probably be used in selection and hence genetic improvement of the local helmeted guinea fowl.
