Weight Gains

Growth data and feed intakes were recorded from 333 male, Friesian calves from birth to 11 weeks of age. The calves came from seven experiments. All calves were weaned from milk replacer at five weeks and fed a starter from two to eleven weeks of age. The average birth weight of the calves was 42.6 kg, they gained 13.6 kg to weaning at five weeks and 32.2 kg from weaning to 11 weeks of age. There was a significant positive correlation between birth weight and weight at weaning and 11 weeks, but the correlation between birth weight and weight gain to 11 weeks was not significant. The correlation coefficient for the weight gain pre-and post-weaning was 0.20 over all calves. There was a significant negative (r = -0.26) correlation between the weight gain post-weaning and the feed conversion ratio. Hence, it is concluded that birth weight is a poor indicator of subsequent weight gains.

Weight Gains

Four diets containing 16% crude protein were formulated with varying levels of groundnut haulms (GNH) and cowpea shell (CPS). The diets designated as Diets 1, 2, 3 and 4, contained 60% GNHI 0% CPS; 40% GNH/20% CPS, 20% GNH/40% CPS and 0%GNH/60%CPS respectively. The diets were fed to sixteen kids of Red Sokoto goats (two males and two females per diet] for seventy days in order to study the effects of varying levels of GNH and CPS on feed intake, nutrient digestibilities and weight gains of the animals. The results showed that the highest dry matter and crude protein intakes by the animals obtained for Diet 2 were 477.30 g/ day and 77. 85g/ day respectively. The lowest water intake per kilogram dry matter intake was obtained on Diet 3 (2. 421). Animals on Diet 2 had a better daily weight gain (85.41g/ day) compared to those on the other diets. The highest feed conversion ratio was obtained on Diet 4 (7.35). Nutrient digestibilities were significantly (p<0.01) affected by treatments, with Diet 2 having the highest and Diet 4 the lowest. Based on higher weight gains for animals on Diet 2, which indicates a shorter time to attain slaughter weight, dieis containing 40% GNH/20%CPS could be recommended for growing Red Sokoto goats.

Performance and organoleptic indices of rabbits fed plantain, oil palm and calopogonium leaves was assessed using 48, eight weeks old bucks. They were allotted to four groups of 12 animals and three replicates of four animals each. Group A (control) was fed calopogonium leaf while groups B, C, and D were fed plantain leaf, oil palm leaf, and 50% oil palm + 50% plantain leaves, respectively. Animals consumed fixed amount of commercial pellets while forages and water were given ad libitum. Completely randomized design, one-way analysis of variance was used. Proximate analysis of pellets and forages as well as feed intake, weight gain and feed conversion ratio were assessed. At the end of the experiment, meat from one rabbit per treatment was used for sensory evaluation by 20 semi-trained panelists using 7-point hedonic scale. Data were analyzed using SPSS software. Significant means were separated using Least Significant Difference. Crude protein, crude fibre, ether extract, nitrogen free extract and ash contents of the leaves ranged from 25.11±1.50 (calopogonium) to 4.90±0.92 (oil palm), 38.40±2.12 (oil palm) to 15.38±0.07 (plantain), 9.71±0.01 (plantain) to 2.30±0.01 (oil palm), 47.80±0.56 (oil palm) to 32.27±0.02 (calopogonium) and 11.93±0.02 (plantain) to 2.99±0.01 (oil palm), respectively. Groups A and B had the highest (p<0.05) final weight and weight gains while groups A, B and C had the highest (p<0.05) forage intake. Feed conversion ratios of groups A and B were better (lower) than others. Forages had no effect on meat colour and texture. Groups B and D meats tasted better than others. Group D meat aroma was better than those fed single forages. Meats from groups C and D were the juiciest while meats from groups A, C and D were the most acceptable. Consideration of final weights, weight gains, feed conversion ratio and taste of meat would require that plantain leaves be used to feed meat rabbits.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Abstract This study aimed to evaluate the effect of zinc supplementation in various diets on the performance and health status of IPB-D2 chickens. Subsequently, about 180 one-week-old IPB-D2 chickens were used in the study and were fed the treatment diets for 12 weeks. Also, this study employed a completely randomised factorial design with six treatments and three replications of ten birds each. These treatment diets included A1, which contained nutrients based on SNI (2013) without Zn supplementation, A2 which is a combination of A1 and 60 ppm of Zinc, B1 which contained nutrients 5% higher than SNI without Zn supplementation, B2 which is a combination of B1 and 60 ppm Zinc, C1 which contains nutrients 10% higher than SNI without Zn supplementation, and lastly, C2 which is a combination of C1 and 60 ppm of Zinc. Furthermore, the data were analysed using ANOVA, and the parameters observed were the body weight, body weight gain, feed consumption, feed conversion ratio, blood profile and the villi surface area of the jejunum. Consequently, the results showed that C2 significantly (P<0.05) increased the body weight and body weight gain when fed to the finisher and grower chickens, respectively. More so, when the finisher chickens were fed the 10% SNI diet, there was an increased body weight gain and also a significantly (P<0.05) decreased feed conversion ratio. Furthermore, the addition of 60 ppm zinc increased haemoglobin significantly (P<0.05), whereas C2 decreased leukocytes significantly (P<0.05) in chicken blood. However, the treatments had no effect on feed consumption in the villi surface area of the jejunum. Therefore, the study concluded that supplementing the IPB-D2 chickens with 60 ppm zinc in a 10% SNI diet resulted in the best performance and health status.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats.

The performance and nutrient retention of broilers fed raw (RMD), toasted (TMD), boiled (BMD), soaked and boiled (SMD) or no (NMD) Mucuna cochinchinensis seed diets at both starter and finisher phases were assessed using 400 broiler chicks. The birds were fed a common proprietary feed (Top Feed) until 2 weeks of age, followed by a treatment diet for 3 weeks of the starter period, then 5 weeks on the finisher diet. At the starter phase, RMD significantly (P < 0.05) decreased liveweight, daily weight gain, protein efficiency ratio and encouraged poorer feed conversion ratio and higher cost per kilogram weight gain when compared with other diets. TMD decreased (P < 0.05) only the protein efficiency ratio. RMD also decreased (P < 0.05) retention of dry matter (DM), crude protein (CP), crude fibre (CF) and energy while TMD decreased (P < 0.05) retention of only DM, CP, and energy. At the finisher phase, RMD also significantly (P < 0.05) decreased daily weight gain, protein efficiency ratio and feed conversion ratio and increased cost per kg weight gain, while TMD decreased (P < 0.05) only the protein efficiency ratio and feed conversion ratio. RMD again decreased (P < 0.05) retention of DM, CP, CF and energy, while TMD, as in the starter phase, again decreased (P < 0.05) retention of DM, CP and energy. On a cumulative basis, RMD adversely affected (P < 0.05) all the parameters under investigation. TMD affected (P < 0.05) only the feed conversion ratio, protein efficiency ratio and cost per kg weight gain. Boiling Mucuna cochinchinensis, therefore, encourages significantly better performance of chicks, higher nutrient retention and lower cost per kg weight gain than toasting, whereas soaking before boiling does not add any advantage to boiling alone.

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.

Abstract This study was conducted to examine the growth performance and expression patterns of growth hormone gene and insulin-like growth factor in metabolic tissues of pigs fed different unconventional feed sources. A total of 45 growing pigs were randomly assigned to 5 dietary treatments at 9 animals per treatment and 3 animals per replicate. Treatment one (T1) comprise of whole maize (WM) which served as the control, T2: brewers dried grain (BDG), T3: cassava peel meal (CPM), T4: plantain peel meal (PPM) and T5: corn husk meal (CHM) at 35% inclusion in the diet. Data collected and analyzed includes; initial body weight (IBW), final body weight (FBW), average daily feed intake (ADFI), average daily weight gain (ADG), feed conversion ratio (FCR) and feed efficiency (FE). At the end of the feeding trial, three animals per treatment (one animal per replicate) were slaughtered; the duodenum and liver were collected and stored using RNALater prior to RNA extraction. Real-time qPCR was performed in 40cycles using the PowerUp SYBR Green reagent and analysed using the Delta-Delta Ct method. All data were subjected to analysis of variance in a completely randomized design. The results showed that the treatment diets had effect on growth performance with significant differences (P &lt; 0.05) observed for average final weight, average total weight gain, average daily feed intake, feed conversion ratio and feed efficiency while the initial weight were not significantly different (P &gt; 0.05). IGF-2 was differentially expressed in the liver and duodenum across treatments while significant differences were not observed in the expression pattern of the growth hormone gene in both tissues. This study showed promise for the use of unconventional feeding stuffs in pig feeding and reveals that genes influencing performance characters are differentially expressed in relation to the source of unconventional feeds used in compounding pig diet.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P &lt; 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P &lt; 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P &lt; 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.
