Total Weight Gain

Sugarcane peels (SCP) is available in large quantities all year round especially in sugar industries where they are discarded as waste product. It contains high amount of carbohydrate and minerals which could be fed to animals especially when properly processed and supplemented with exogenous enzyme to aid the animal digest it. Fifty - four weaned 4-5 weeks old crosses of New Zealand white x Chinchilla male rabbits were utilized to evaluate the effect of feeding sugarcane peel meal-based diets supplemented with quantum blue® on the growth performance parameters (initial weight, final weight, weight gain, feed intake, FCR and feed cost per weight gain) and nutrient digestibility by weaner rabbits. Six diets were formulated to be iso-nitrogenous (18% crude protein) and isocaloric (2700kcal/kg, ME) with two levels of inclusion of sugarcane peel meal (SCPM) (low and high) and three levels of enzyme supplementation (0, 150 and 250 PPM) giving a 2x3 factorial arrangement fitted into Completely Randomized Design. The rabbits were weighed and allotted to the treatments at the rate of 3 rabbits per replicate and each treatment was replicated 3 times. Feeds were weighed and served to the animals individually and water was provided ad-libitum. Growth parameters and nutrient digestibility data were generated and evaluated. The results of the effect of enzyme on growth performance of weaner rabbits showed that average total weight gain significantly (P<0.05) improved as rabbits fed the 200PPM enzyme supplemented diets had the best value of 511.67g/rabbit. However, rabbits fed the 100PPM performed (410.83g/rabbit) the same as those fed the 200PPM. Similarly, rabbits fed the 200PPM enzyme supplemented diets gained more (P<0.05) daily weight of 10.40 g/rabbit/day followed by those fed the 100PPM (8.32 g/rabbit/day). The result of the effect of high SCPM showed that feed intake significantly (P<0.05) increased from 47.37 g/rabbit/day to 59.82 g/rabbit/day as the level of SCPM increased in the diets; rabbits fed the high SCPM had higher total weight gain of 484.44 g/rabbit as compared to those of low SCPM (362.78 g/rabbit). The interactive effects of SCPM and enzyme on growth performance of weaner rabbits showed that final live weight, feed intake and total weight gain were significantly (P<0.05) improved as the levels of SCPM and enzyme increased in the diets. In view of the findings, rabbit farmers can supplement 32% of SCPM in the diets of  weaner rabbit with 200PPM of quantum blue® without negatively affecting the growth rate and suppressing the digestibility of nutrients by weaner rabbits.

This study was conducted to determine the growth performance and nutrient digestibility ofbroiler chickens fed wood-ash based diet. A total of 120 broiler chickens were randomlyallocated to four treatments in the completely randomized design. Treatment 1 was thecontrol while Treatments 2, 3, and 4 were Neem ash (NTA), Shea butter ash (SBA) and Locustbean ash (LBA), respectively. Each treatment has three replicates and ten birds per replicate.Data on growth rate, live weight, feed intake and mortality were collected while feedconversion ratio was calculated. Apparent dry matter, crude protein, crude fibre, etherextract and nitrogen free extract retention were also determined. All data collected wereanalyzed using one-way analysis of variance. Starter phase results shows that birds on SBA ash had the highest final weight (366.00 g), body weight gain (173.71 g) and feed intake (546.03 g) and were significantly higher (p<0.05) than the control. At the finisher phase, all ash treatment had higher (p<0.05) final, daily weight gain and better (p<0.05) feed conversion than the control dietary. The digestibility results indicated birds on LBA diet had the highest crude fibre and ash content. The study showed that wood ash influenced growth performance and nutrient retention of broiler chickens. Chickens on ash-based diets performed better that the control at the finisher phase.

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

Kajli, is one of the most beautiful sheep breeds of Pakistan. Because of their beauty, Kajli lambs are sold at a higher price than those of other breeds with similar weight. With the increasing trend in commercial livestock farming, young Kajli lambs are purchased from the open market and reared up to Eid-ul-Adha (The Muslim Sacrificial Day). Information on feeding cost and growth performance on artificial rearing is important for the breed lovers and for a commercial enterprise. The present study aimed at generating basic information on feeding cost and growth performance of Kajli lambs offered milk replacer, cow-milk, and buffalo-milk, in comparison with those suckling directly from their dams. Fifty-six healthy Kajli lambs both male and female (with equal sex ratio) born at the Livestock Experimental Station, Khushab, Punjab, Pakistan during spring 2013 remained with their mothers for 1 week and were then divided into four groups of 14 animals each. Lambs in Group I were allowed to suckle their dams ad libitum, twice daily until 8 weeks and then once daily from 9 to 12 weeks. Lambs were weighed before and after suckling to calculate milk consumption. Lambs in the other three treatments were offered buffalo-milk, cow-milk or milk replacer at the rate of 10% of bodyweight until the 8th week and then gradually reduced to zero by the end of the 12th week. All lambs were offered starter ration from the 5th week of age in individual pens. The data on milk and starter intake, weekly bodyweight and blood glucose were analysed through MIXED procedures of SAS using repeated-measures analysis, and average daily gain (ADG), total weight gain, weaning weight and feeding cost were analysed using a completely randomised design. Least square means of ADG (g/day) and total weight gain (kg) were similar (P > 0.05) in direct suckling lambs and lambs offered buffalo-milk (175 and 151, and 14.5 and 12.5, respectively), and were higher (P < 0.05) than those offered cow-milk (118 and 10.4) or milk replacer (94 and 7.7). Feeding cost (per kg of liveweight) was highest (PKR 535) in lambs fed milk replacer and was lower (P > 0.05) in the other three groups. The cost of rearing lambs on buffalo-milk tended to be lower (PKR 375) than those offered cow-milk. In the absence of ewe’s milk, rearing Kajli lambs on buffalo-milk during the pre-weaning period therefore seems to be a better alternative.

Abstract This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

A total of 48 large white pigs were used in an experiment to investigate the use of exogenous testosterone on the growth of pigs. The pigs were randomly selected as day old piglets, balanced for weight with equal number for each sex, and allotted to two treatment groups, T1, which received Testosterone Enanthate (TE), intramuscularly, weekly, for 24 weeks and T2, the control, which received no hormone but blank injections. Dosage was based on live weight (1.2mg/kg live weight). Corn oil served as the vehicle. The parameters measured include Total weight gain (TWG), Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and Feed Conversion Ratio. The results obtained showed that exogenous testosterone increased weight gain significantly (p<0.05) in both sexes than their respective controls. The same trend was observed for feed intake and feed conversion. Exogenous testosterone also indicated pronounced sex effect on the pigs in this study with males having significantly (p<0.05) higher values than females. It can be concluded from this study that exogenous testosterone can be used to accelerate growth thereby finishing the pigs early. A withdrawal period of 4 weeks before slaughter is however recommended.

This study was carried out to evaluate the effect of 45 minutes Boiled Mucuna Seed Meal (BMSM) on the growth performance and nutrient digestibility of broiler finisher chicks. In a four-week feeding trial, three hundred and fifteen (315),4-week old broiler chicks were  randomly allocated to five experimental treatment diets in a completely randomized design (CRD). Each treatment was replicated thrice having twenty-one (21) birds per pen. Boiled Mucuna seed meal was prepared and fed in graded levels of 0.0% (control diet), 10.0%, 20.0%, 30.0%, and 40.0%BMSM. Feed and water were given to the birds ad libitum. The parameters measured and calculated include final weight, weight gain, feed intake, feed to gain ratio and feed cost per kilogram gain. Digestibility of dry matter, crude protein; crude fibre, ash, nitrogen free extract and ether extract were also determined. The data collected were subjected to analysis of variance (ANOVA). The results showed that dietary levels of inclusion of BMSM had significant (P<0.05) effect on these parameters. The final weight, the weight gain and feed intake of the birds fed 0.0%, 10.0% and 20.0%BMSM were statistically (P>0.05) similar and significantly (P<0.05) higher than those of other treatments. Cost of feed per birds and feed cost per kilogram gain were lower for all BMSB diets.Digestibility of nutrients was better for the birds fed the control,10.0 and 20.0%BMSM based diets. It was concluded that inclusion of BMSM in the diets of broiler finisher chicks up to20% has no deleterious effect on growth performance and nutrient digestibility of the birds.     Cette étude a été réalisée pour évaluer l'effet de 45 minutes de farine de graines de Mucuna (le 'BMSM') bouillie sur la performance de croissance et la digestibilité des éléments nutritifs des poussins finisseurs de poulet à griller. Dans un teste d'alimentation de quatre semaines, trois cent quinze (315), poussins de poulet de griller de 4 semaines ont été aléatoirement attribués à cinq régimes expérimentaux de traitement dans une conception complètement randomisée (le 'CRD'). Chaque traitement a été reproduit trois fois avec vingt et un (21) oiseaux par enclos. Le repas bouilli de graine de Mucuna a été préparé et alimenté dans les niveaux classés de 0.0% (régime de contrôle), 10.0%, 20.0%, 30.0%, et 40.0%BMSM. L'alimentation et l'eau ont été données aux oiseaux ad libitum. Les paramètres mesurés et calculés comprennent le poids final, le gain de poids, la prise d'aliments pour animaux, le rapport alimentation/gain et le coût des aliments pour animaux par gain kilogramme. La digestibilité de la matière sèche, protéines brutes; des fibres brutes, des cendres, de l'extrait sans azote et de l'extrait d'éther ont également été déterminés. Les données recueillies ont fait l'objet d'une analyse de la variance (ANOVA). Les résultats ont montré que les niveaux diététiques d'inclusion de 'BMSM' ont eu un effet significatif (P<0.05) sur ces paramètres. Le poids final, le gain de poids et la prise d'alimentation des oiseaux nourris 0.0%, 10.0% et 20.0%BMSM étaient statistiquement (P>0.05) semblables et significativement (P<0.05) plus élevés que ceux des autres traitements. Le coût de l'alimentation animale par oiseau et le coût de l'alimentation par kilogramme étaient inférieurs pour tous les régimes BMSB. La digestibilité des éléments nutritifs était meilleure pour les oiseaux alimentés le contrôle,10.0 et 20.0% BMSM régimes à base. Il a été conclu que l'inclusion du BMSM dans l'alimentation des poussins finisseurs de poulet de gril jusqu'à 20 % n'a aucun effet délétère sur la performance de croissance et la digestibilité des oiseaux en matière d'éléments nutritifs.

Bull Calves

An experiment was conducted for a period of 60 days with twelve bull calves with an average live weight of 77.78 ± 10.96 kg to determine the effect of treatment of rice straw with Wood Ash Extract (WAE) on feed intake, nutritive value, growth rate and economic benefits. The experimental animals were divided into three groups A, B and C having four animals in each. They were supplied randomly with three rations following randomized complete block design. All rations were made iso-nitrogenous by using urea as a source of nitrogen. Animals of group A were fed untreated rice straw, whereas, group B and C were fed urea-treated and WAE treated rice straw, respectively. The chemical analysis showed that treatment of rice straw with WAE increased ash content of straw from 13.93% to 16.45% and decreased the NDF content from 67.39% to 63.00%. The daily DM intake per 100 kg live weight of diet B was significantly (P<0.01) higher than that of diet A and C. The daily CP intake per 100 kg body weight of diet B (553.3g) was significantly (P<0.05) higher than that of diet A (449.5g). Similarly, the organic matter (OM) intake in bull calves fed diet B was significantly (P<0.05) higher than those fed diet A and C. The average daily live weight gain with diet B and C was significantly (P<0.01) higher than diet A. The animals fed diet B and C were more efficient in converting feed into live weight than animals fed diet A. Treating rice straw with wood ash extract improved the nutritive value, it significantly (P<0.01) increased the apparent digestibility of DM, OM, CP, ADF and NDF. It also increased the DCP, DOM, DNDF and DADF contents of rice straw compared with untreated straw. Although the total feed cost of untreated group is lower than those of WAE and urea-treated groups, the feed cost per kg live weight gain as well as the feed cost per kg meat production of WAE and urea-treated groups were significantly (P<0.01) lower than that of untreated rice straw. It may be concluded that nutrient composition and digestibility of rice straw and live weight gain of animals can be improved by treating rice straw with wood ash extract.

An experiment was conducted to evaluate efficacy of Lacto acidophilus on the growth performance, carcass characteristics and nutrient digestibility of broiler chickens. Two hundred and twenty five (225), one day old chicks were purchased from local commercial hatchery and were randomly divided into 5 groups and each group had 3 replicates of 17 chicks in a completely randomized design. Five iso-caloric and iso-nitrogenous (ME 2998kcal/ kg and CP 23.21%) broiler starter and finisher (ME 2990 kcal/ kg and CP 20.33%) experimental diets containing 0, 150, 200 and 250g Lacto acidophilus® for T1-T4 respectively and T5 containing Oxytetracycline were formulated. Broiler starter and finisher diets were fed from 0-3 and 4-7 weeks, respectively. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatments means were separated using Duncan Multiple Range Test. There were significant (P<0.05) difference in final weight, weight gain, average daily weight gain (ADWG), total feed intake (TFI), average daily feed intake (ADFI), feed conversion ratio (FCR) and feed cost/kg gain across the treatment groups. It was observed that chickens fed dietary Oxytet (oxytetracycline) had the best results in terms of the final body weight, weight gain and ADWG but similar to those fed 150 and 200g Lacto acidophilus® addition levels. The percentage dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and ash retention increased with increase in Lacto acidophilus® inclusion with exception for 250gLacto acidophilus® inclusion (CP, CF, EE). However, it was observed that chickens fed dietary levels of Lacto acidophilus® had the best live weight, dressed weight and dressing percentage compared to the control group. It was concluded that chickens fe Lacto acidophilus® inclusion may as well compete favorably with antibiotics growth promoter fed chickens.     Une expérience a été menée pour évaluer l'efficacité de Lacto acidophilus sur la performance de croissance, les caractéristiques de la carcasse et la digestibilité nutritive des poulets de gril. Deux cent vingt-cinq (225), poussins d'un jour ont été achetés à l'écloserie commerciale locale et ont été répartis au hasard en 5 groupes et chaque groupe avait 3 répliques de 17 poussins dans une conception complètement randomisée. Cinq iso- caloriques et iso-azotés (le 'ME' 2998kcal/kg et le 'CP' 23.21%) démarreur et finisseur de poulet de gril (le 'ME' 2990 kcal/kg et le 'CP' 20.33%) des régimes expérimentaux contenant respectivement 0, 150, 200 et 250 g d'acidophilus lacto® pour le T1-T4 et le T5 contenant de l'Oxytetracycline ont été formulés. Les régimes d'entrée et de finisseur de poulet de gril ont été alimentés de 0-3 et 4-7 semaines, respectivement. Les données obtenues ont fait l'objet d'une analyse de la variance à l'aide du système d'analyse statistique et des différences significatives entre les moyens de traitement et ils ont été séparées à l'aide du test à distance multiple Duncan. Il y avait une différence significative (P<0,05) dans le poids final, le gain de poids, le gain de poids quotidien moyen (le 'ADWG'), la consommation totale d'aliments pour animaux (le 'TFI'), l'apport quotidien moyen en aliments pour animaux (ADFI), le ratio de conversion des aliments pour animaux (FCR) et le gain coût/kg des aliments pour animaux dans les groupes de traitement. On a observé que les poulets nourris oxytet alimentaire (oxytetracycline) ont eu les meilleurs résultats en termes de poids corporel final, gain de poids et de 'ADWG', mais similaire à ceux nourris 150 et 200g Lacto acidophilus® niveaux d'addition. Le pourcentage de matière sèche (le 'DM'), de protéines brutes (le 'CP'), de fibres brutes (le 'CF'), d'extraits d'éther (le 'EE') et de rétention de cendres a augmenté avec l'augmentation de lacto acidophilus® l'inclusion à l'exception de 250 glacto acidophilus® inclusion (CP, CF, EE). Cependant, il a été observé que les poulets nourris à des niveaux alimentaires de Lacto acidophilus® avaient le meilleur poids réel, le poids habillé et le pourcentage de vinaigrette par rapport au groupe témoin. Il a été conclu que les poulets feLacto acidophilus® inclusion peut aussi bien rivaliser favorablement avec les antibiotiques promoteur de croissance nourris poulets.

A seventy-day feeding trial was conducted to investigate the effect of dietary fibre and digestible energy (DE) level on growth performance, apparent nutrient digestibility and caecal fermentation of growing rabbits. The experiment was laid out in a 3 × 3 factorial arrangement of 3 levels of fibre (low (249 – 258 g/kg NDF, 149 - 157 g/kg ADF), optimum (349 – 381 g/kg NDF, 188 - 193 g/kg ADF) and high (430 – 456 g/kg NDF, 249 - 253 g/kg ADF)) and 3 levels of DE (low (8 – 8.5 MJ/kg), optimum (10.5 – 11 MJ/kg) and high (12 – 12.30 MJ/kg)). A total of one hundred and thirty five weaner rabbits were allotted to 9 dietary groups of 15 rabbits each. Main effect of fibre showed that the final live weight and weight gain of rabbits increased (P < 0.01) while Ca retention reduced (P < 0.001) with increasing dietary fibre level. Rabbits fed (249 – 258 g/kg NDF, 149 - 157 g/kg ADF), had the worst (P < 0.05) feed to gain ratio. Rabbits fed (349 – 381 g/kg NDF, 188 - 193 g/kg ADF) had the highest apparent dry matter (P < 0.05), ether extract (P < 0.05), NDF (P < 0.001), ADF (P < 0.001) and organic matter digestibility (P < 0.001). Main effect of DE showed that rabbits fed high DE recorded the highest (P < 0.05) weight gain. Highest (P < 0.01) apparent dry matter, crude protein, ash, NDF, ADF, organic matter digestibility and Ca retention were recorded with rabbits fed optimum DE diet. Rabbits(445.70g/kgNDF, 252.10g/kgADF and 8.01MJ/Kg) recorded the highest (P < 0.001) final live weight, weight gain and feed intake (P<0.05) while rabbits fed (249 g/kg NDF, 149 g/kg ADF and 8.17MJ/Kg) had the least (P < 0.001) final live weight, weight gain, apparent dry matter digestibility, NDF and ADF digestibility. Highest (P<0.001) NDF digestibility was obtained with rabbits fed (370.79 g/kg NDF, 189.61 g/kg ADF and 10.84MJ/kg). Not withstanding the DE level of the diets, rabbits fed with (430 – 456 g/kg NDF, 249 - 253 g/kg ADF) recorded the highest (P<0.05) total VFA and acetic acid concentration. Rabbits fed (445.7g/KgNDF, 250.09g/KgADF and 10.52MJ/kg) recorded the best growth performance, improved caecal fermentation with no adverse effect on apparent nutrient digestibility.
