A total of 120, day-old turkey (Maleagris gallopavo) chicks were arranged into four groups. Four diets having varying levels of crude protein (CP) viz. 16% CP, 18% CP, 20% CP and 22% CP were prepared and were designated as control (T0), treatment 1 (T1), treatment 2 (T2) and treatment 3 (T3) diets, respectively. Group 1 birds were fed with T0 diets, group 2 with T1 diets, group 3 with T2 and group 4 birds were fed with T3 diets. Significantly higher weight gain 2950.86±1952.58g, body length 30.064±11cm, beak length 3.53cm, body girth 43.41±16.30cm, thigh length 18.18±6.47cm, sternum-length 11.98±4.70cm, wing-length 47.10±16.17cm, wingspan 101.36±34.32cm, shank-length and tarsus-length 13.78±4.47cm were recorded in M. gallopavo fed with T3 diets. Feed conversion ratios (FCR) for T0, T1, T2 and T3 diets were 2.296, 2.236, 2.099 and 1.934, respectively. Internal and external quality parameters of egg were also analyzed.

“…It's therefore evidenced that lower egg weight at incubation will affect the keet weight at hatch and reduce subsequent growth performances of the young birds (Figures 1, 2, 3 and 4). Nguefack et al, (2022) reported much lower live weight (< 500 g in all treatments) at 8 weeks of age with varied levels of crude protein in diet of guinea fowl compared to what was obtained in this present study. Keets from small egg weight category had even better live weight (512.5 g) at 8 weeks of age, followed by those from the medium category (522.9 g) and the large category (605.42 g) compared to the average live weight reported by Nguefack and co.…”

A study was carried out to characterize guinea fowl (Numida meleagris) eggs, evaluate the effect of egg weight on hatchability, keet hatch-weight and early growth performance in the Western Highlands of Cameroon. One hundred and seventy-four (174) guinea fowl eggs were collected from a farm in the West Region of Cameroon and characterized. Length, width and weight of eggs were recorded. Using egg weight and egg shape indices, eggs were grouped into small (40-45 g); medium (46-49 g) and large (>50 g) categories and incubated for 32 days. Keets were collected at hatch as from 28 days of incubation from each group and weighed to determine their baseline weight post-hatch. Fertile and infertile eggs were separated through candling and breaking of unhatched eggs to count dead in shell embryos. Keets resulting from each category of small (T1), medium (T2) and large (T3) were maintained, with each treatment having 15 keets. Keets received water and a commercial diet containing 2900Kcal/kg of ME and 22% CP for the first 3 weeks of age and 2800 kcal/kg of ME and 20% of CP for the next 10 weeks of study ad-libitum. For 13 weeks, early growth performance (weight evolution, weight gain, Feed intake and FCR) were evaluated. Results revealed that egg weight ranged from 40 g to 59 g. The overall mean weight of guinea fowl eggs obtained was 48.52 g with mean egg weight of 43.75 g, 47.66 g and 51.60 g for small, medium and large categories respectively. Eggs in all treatments showed significant difference (p<0.05) in fertility rates with eggs in the large category showing the highest fertility. Eggs in the large category had the highest hatchability though not significantly different (p>0.05) compared with the small category. Highest mean keet weight at hatch were obtained with the large category and were significantly (p<0.05) higher compared with those of the small category. Regression analysis revealed that an increase in egg weight resulted in a corresponding significant increase in keet hatch rate (r2=0.95) and that there exist a positive relationship between egg weight and keet hatch weight with a regression coefficient of r2=0.94. The mean weekly and daily feed intake per bird were higher in the large category than in the other groups. Similar observations were obtained with the weight gains. However, the medium category showed the lowest overall mean feed conversion ratio. In conclusion egg size had significant effects on hatchability of guinea fowl eggs and post hatch keet weight. Larger sized eggs had higher hatchability and better keet weight at hatch with keets from the large and medium sized eggs showing better growth performances than those from the small egg sized category. Therefore, guinea fowl egg weight ranging from 45 g to 60 g is most suitable for incubation as it yields better hatchability and keet weight post hatch as well as post hatch growth performance. Une étude a été réalisée pour caractériser les oeufs de pintade (Numida meleagris), évaluer l’effet du poids des oeufs sur l’éclosion, le poids d’éclosion des pintadeaux et les performances de croissance précoce dans les hauts plateaux de l’ouest Cameroun. Cent soixante-quatorze (174) oeufs de pintade ont été collectés dans une ferme de la région de l’Ouest du Cameroun et caractérisés. La longueur, la largeur et le poids des oeufs ont été enregistrés. À l’aide des indices de poids et de forme des oeufs, les oeufs ont été regroupés en petits (40 à 45 g); moyennes (46-49 g) et grandes (> 50 g) catégories et incubées pendant 32 jours. Les pintades ont été collectées à l’éclosion à partir de 28 jours dans chaque groupe et pesées pour déterminer leur poids à l’éclosion. Les oeufs fertiles et stériles ont été séparés par mirage et cassage des oeufs non éclos pour compter les embryons morts dans leur coquille. Les pintades issues de chaque catégorie de petite (T1), moyenne (T2) et grande (T3) ont été maintenues, chaque traitement comportant 15 pintadeaux. Les pintadeaux ont reçu de l’eau et un régime alimentaire commercial contenant 2 900 Kcal/kg de EM et 22 % de PB pendant les 3 premières semaines d’âge et 2 800 kcal/kg de EM et 20 % de PB pendant les 10 semaines de l’étude à satiété (ad-ibitum). Pendant 13 semaines, les performances de croissance précoce (évolution du poids, gain de poids, consommation alimentaire et indice de consommation) ont été évaluées. Les résultats ont révélé que le poids des oeufs variait entre 40 g et 59 g. Le poids moyen des oeufs de pintade obtenus était de 48,52 g avec un poids moyen des oeufs de 43,75 g, 47,66 g et 51,60 g pour les petites, moyennes et grandes respectivement. Les oeufs de tous les traitements ont montré une différence significative (p <0,05) dans les taux de fécondité, les oeufs de grande taille ayant la fertilité la plus élevée. La grande catégorie avait le taux d’éclosion le plus élevé, mais sans différence significative (p>0,05) par rapport à la petite catégorie. Les poids moyens les plus élevés à l’éclosion ont été obtenus avec la grande catégorie et étaient significativement (p < 0,05) plus élevés que ceux de la petite catégorie. L’analyse de régression a révélé qu’une augmentation du poids des oeufs entraînait une augmentation significative correspondante du taux d’éclosion des volailles (r2 = 0,95) et qu’il existe une relation positive entre le poids des oeufs et le poids d’éclosion des volailles avec un coefficient de régression de r2 = 0,94. La consommation alimentaire moyenne hebdomadaire et quotidienne par oiseau était plus élevée dans la catégorie des grands que dans les autres groupes. Des observations similaires ont été obtenues avec les gains de poids. Cependant, la catégorie moyenne a montré indice de consommation moyenne le plus basse. En conclusion, les fourchettes de taille des oeufs ont eu des effets significatifs sur l’éclosion des oeufs de pintade et sur le poids des pintades après l’éclosion. Les oeufs de plus grande taille présentaient une plus grande capacité d’éclosion et un meilleur poids à l’éclosion, les pintadeaux des oeufs de grande et moyenne taille présentant de meilleures performances de croissance que celles de la catégorie des oeufs de petite taille. Par conséquent, un poids d’oeufs de pintade allant de 45 g à 60 g est le plus approprié pour l’incubation car il donne une meilleure capacité d’éclosion et un meilleur poids de pintade après l’éclosion ainsi que de meilleures performances de croissance après l’éclosion.

“…We could explain the performance drop with the dose of 4.5%, by the exceeding of optimal level of energy needed to chickens. Kuietche et al (2014) made a similar observation about local barred chicks that have recorded higher feed conversion ratio when energy level in the ration is less than 2700 kcal / kg or greater than 2900kcal / kg. It could also be due to a decrease of digestibility of the feed due to sorghum used for the probiotic feed ingredient production.…”

The use of antibiotics in human or veterinary therapy is followed by the appearance of bacteria resistance to these antibiotics. This is a serious problem because of the direct impact on therapeutic possibilities. This study aimed at evaluating the efficiency of a probiotic feed ingredient (Starter) on the growth performance of broiler (Hubbard) to allow a reduction of the use of antibiotics. The experimental design consists of four treatments with three replications: diets with 0%, 1.5%, 3% and 4.5% of the probiotic feed ingredient. Each replication consists of 18 broilers with an average live body weight of 43.04 ± 6.38 g. After seven (7) weeks of trial, chickens receiving the treatment .T1.5 had the best growth with an average weight of 984.22 ± 249.2 g, but with no significant difference (P> 0.05). In this treatment, their feed intake was the highest (51.38 g/bird/day) while the feed conversion rate turned out to be the lowest (6.67 g feed/g Live body weight). The highest value of carcass yield (76.1%) and sternum proportion (5.54%) were obtained in treatment T3. From the above results, we can state that the probiotic feed ingredient included at 1.5% and 3% improved growth performance of broilers. It could help to significantly improve the production performance of broilers if its probiotics properties are enhanced.
