Feeding Level

A study was conducted to determine the effect of feed quantity offered (1.5, 2.0 or 2.5 kg) on growth performance, carcass yield, organs weight and backfat composition. A total of 48 Large White grower male pigs with initial average weight of 36.48±2.25 kg were allotted to 3 treatments of 16 pigs per treatment and were further replicated into 4 with 4 pigs per replicate. Data were collected on weekly basis and carcass characteristics were performed when the pigs on each experimental group attained an average weight 70 kg. Final body weight, daily weight gain and daily feed intake were significantly (P<0.05) increased by feeding level with highest mean values obtained by the pigs fed 2.5 kg feed daily. Pigs on 1.5 kg daily feeding level took 108.31 days to attain the target weight of 70 kg which was significantly (P<0.05) longer than 92.23 and 79.94 days obtained by those on 2.0 and 2.5 kg daily feeding levels respectively. Most of the parameters considered for carcass yield were not significantly (P>0.05) enhanced by feed quantity offered. The weight of ham (11.54, 12.18 and 13.41%) increased significantly (P<0.05) with increase in feeding level while kidney weight decreased significantly (P<0.05) with increase in feed quantity offered. Heart values of the pigs fed 2.0 and 2.5 kg feed daily were similar but differed significantly from those fed 1.5 kg feed daily. The depth of fat at first and last ribs, and subcutaneous fat depth increased significantly (P<0.05) with increase in feeding level. These results showed that quantity of feed offered greatly influenced growth performance (final body weight, daily weight gain, daily feed intake and days to target weight), ham, kidney, heart and backfat composition of finishing pigs, hence, it could be used as a management tool to improve growth performance and carcass traits of pigs.

The objective of this study was to develop the least-cost starter&rsquo;s diet and evaluated its effect on the growth performance of Sasso breeds and Indigenous ecotype of chicks under the local condition of the South Gondar Zone. The effects of substitution of different levels of commercial starters ration with homemade diet on the growth performance of Sasso and Indigenous chicks were studied in Hiruy Abaregay village of Farta district. The research area is 586km distant from the capital city of Addis Ababa, Ethiopia. A total of 510 Sasso T-44 and 90 Indigenous local ecotypes day-old chicks were randomly divided into five groups, each with 102 and 18 chicks, respectively. These were assigned into five treatments in which 100 (T1), 75 (T2), 50 (T3), 25 (T4), and 0% (T5) of commercial starter&rsquo;s diet in factorial completely randomized design (CRD) with 3 replications for 60 days feeding period. The results obtained indicated that increased levels of substitution of a commercial diet with a homemade diet significantly depressed (p&lt;0.001) mean daily feed consumption and retention of dry matter, nitrogen, and metabolizable energy. Growth rate as measured by mean daily weight gain, mean final body weight, and total feed consumption and feed cost were significantly miserable (p&lt;0.001) in an increased homemade diet. On the contrary, there was an increase in feed conversion ratio and fiber content in high-level dilution of starter&rsquo;s commercial diet with a homemade diet. However, the groups of chicks on 0, 25, and 50% commercial starters diets replaced by homemade diet were significantly higher (p&lt;0.001) in mean daily feed intake, daily weight gain, feed conversion ratio, and final body weight attained. The results of this study indicated that up to 50% of expensive commercial starter&rsquo;s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

This study was conducted to evaluate the growth performance and haematological profiles of broiler chickens served dietary inclusion of probiotics (Saccharomyces cereviasae) and enzyme (Bio-enzyme). One hundred and twenty, one day-old broiler chicks of Agrited strain were used for the study. The birds were randomly allotted to four dietary treatments. Each treatment contained 30 birds replicated three times to contain 10 birds per replicate in a completely randomized design experiment. The four dietary treatments were T1 Control (no probiotics and enzyme), T2 (had both probiotics and enzyme), T3 (probiotics only) and T4 (Enzyme only). The birds were given feed and water ad-libitum and the quantity of feed consumed each day was determined through weigh back techniques while the birds were weighed weekly throughout the experimental period. The experiment lasted eight weeks. The results showed significant (p<0.05) differences in the final body weight, total weight gain, average daily weight gain, total feed intake, average daily feed intake and feed conversion ratio. Chickens on treatment 2 had the highest final body weight of 3011.57g and performed better than chickens in other dietary treatments. Similar trend was observed in the haematological profile as treatment two were highest in value across the treatments and parameters measured except in packed cell volume where the highest value (36.33 %) was recorded in treatment 4. It was concluded from the study that treatment two which contained both probiotics and enzyme performed better and thus, recommended to farmers for broiler production.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.

This study was conducted to assess the effects of abattoir wastes (bovine blood and rumen content mixture) on the haematology and growth performance characteristics of broiler birds. One hundred and twenty (120) unsexed day old Abor acre broiler chicks were randomly assigned to 4 treatments and replicated 3 times in a completely randomized design (CRD) experiment. Four experimental diets were formulated to meet the nutrient requirement of broilers such that the birds were fed sundried abattoir waste (bovine blood and rumen content mixture) included at 0%, 5%, 10% and 15% representing Diet 1, 2, 3 and 4 respectively, with Diet 1 as the control. Each dietary treatment consists of 30 birds with 10 birds per replicate. The experimental diets and clean water were supplied at- libitum throughout the experimental period. Data were collected on feed intake, daily weight gain, final body weight, weight gain. Feed conversion ratios were calculated. Blood samples for hematology was collected, analyzed and recorded. At the end of the 56 days feeding trials, data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that mixtures of bovine blood and rumen content significantly (P<0.05) improved the final weight (1767.02g -1931.44g), weight gain (1367.02g -1528.44g), feed intake (107.47g -118.99g) and feed conversion ratio (4.87 – 4.08) of the broilers. Significant (P<0.05) improvements were observed on the RBC, WBC, MCV, MCH, eosinophyls and the lymphocytes of the haematological parameters of the broilers. These results showed the complementary potentials of bovine blood and rumen content mixture in broiler diets, which can be included up to 15% in the ration of broilers without detrimentally affecting the growth performance and haematology of the broilers.

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.

Supplementation with complexed minerals influences the growth performance and the integrity of the locomotor system of animals. The aim of this study was to determine the effect of a complex supplementation of organic minerals (metal-amino acids) consisting of Zn (50 ppm), Mn (20 ppm), and Cu (10 ppm) (Availa® Sow FF Zinpro Corp.) on the growth performance and integrity of the locomotor system in pigs. One hundred and eighty 61-day-old animals, comprised of females (n=90) and castrated males (n=90), were used in a randomised block factorial design with ten replicates per treatment and sex. The experimental design consisted of two treatments: control (T1) animals without supplementation and treatment (T2) animals that were supplemented with organic minerals (0.75 g kg-1). At 112 days of housing (D112), the pigs were subjected to a hoof evaluation, at D115 they were weighed, and at D117, they were slaughtered (178 days of age). After boning, a blind analysis was performed on the medial and lateral condyles of the distal humerus. The supplemented animals (T2) had higher scores for the performance parameters of final weight (P=0.03), weight gain (WG) (P=0.02), and average daily weight gain (DWG) (P=0.021). For WG, T2 showed 3.10 kg more gain than the control; the increase in females was on average 4.07 kg and in males 2.45 kg. The prevalence of hoof lesions was 100% in both groups. The supplementation reduced the incidence of damage to the dew claws (P=0.02) and heel-sole cracks (P=0.02). The incidence of osteochondrosis was 19.13%, with no influence of supplementation. Supplementing pigs with the organic minerals Zn, Mn, and Cu during the finishing phase improved the WG, DWG, final weight, and hoof integrity.

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this fermented cassava flour/blood mixture code-named "cassablood". The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30% cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD). Treatment effects on final body weight, final weight gain, feed intake and seed conversion ratio were significant (P<0.05). Birds fed cassablood based diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio.All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contentswhichdiffered (P<0.05) significantly. Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.
