Abstract This study investigated the effect of pasture grazing on growth performance and blood characteristics in nine-month-old Hanwoo (native Korean cattle) steers. Thirty one steers were randomly assigned to three groups: (CON) Italian ryegrass and concentrate (1.6% BW) until 14 month of age, (G1) pasture grazing 101 days without concentrate, (G2) pasture grazing 101 days and concentrate (1.6% BW). Initial BW of CON, G1 and G2 were 255 kg, 238 kg and 254kg respectively. Average daily gains were higher in CON (1.02 kg) and G2 (0.92 kg) than G1 (0.62 kg) (p >0.05). Final weight and total weight gain were higher in the feeding concentrate (1.6% BW) groups (Con and G2) compared to the G1. Blood characteristics, such as such as total cholesterol (T-CHO), triglycerides (TG) and non-esterified fatty acid (NEFA) were investigated to test the effects on health and energy metabolism. T-CHO, an index of fat metabolism and liver function, was lower in Con (119.75 md/dL) and G2 (107.13md/dL) than G1 (87.79 mg/dL). TG was higher in Con (21.63 IU/L) than G1(15.14 IU/L) (P< 0.08). NEFA was higher in G2 (384 uEq/L) than other groups (Con 138 uEq/L and G1 225 uEq/L). These results show that concentrates supplementation during grazing period is needed to increase BW of Hanwoo steer in the growing state.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

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.

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.

The cost of feed is the main cause of high cost of production of rabbits. Kolanut testa, a protective covering of the kolanut seed (Cola nitida) is readily available as by-product in areas where kolanut is produced. Thus, the objective of this study was to assess the growth performance, carcass attributes, haematological parameters and economics of production of rabbits fed diets with varying inclusions levels of kolanut testa (KOT) as replacement for maize. Thirty mixed breed rabbits of mixed sexes were used for this experiment. The rabbits were randomly allotted into 5 treatment groups. Five experimental diets were formulated such that KOT replaced maize at 0, 10, 20, 30 and 40%. Records of feed intake and weight gain were properly taken and blood samples were collected and analysed for their haematological parameters at the end of the experiment. Cost analysis using dedicated formulae was done to determine economics of production. The experiment lasted for eight weeks. Data were analyzed using Analysis of Variance. No significant (P>0.05) difference was recorded in all the parameters measured to determine growth performance. The same applies to parameters measured for carcass attributes except for weight of limbs. Significant (P<0.05) difference was however recorded among mean values of PCV (28.67-36.33%), 6 3 3 3RBC (3.14-4.12x10/mm), WBC (3.10-5.87x10/mm) and Mon (1.40-1.67%) of the experimental animals. Cost of feed decreased with increase in KOT inclusion (N139.8N112.54). Cost of feed (N/kg) weight gain (N1023.61-N583.04); cost of weight gain (N573.22-N483.92); and total cost (N2143.61-N1523.92) all followed similar pattern. Cost differential (205.93–440.04) and relative cost benefit (20.11–43.04%) increased with increase in the level of replacement of KOT. Conclusively, growth performance was not negatively affected and total weight gain was numerically highest at 40% (916.67g) with no deleterious effect on the health of the rabbits. Also, the highest relative cost benefit was recorded at 40% (28.54%). These prove that KOT is a viable substitute for maize in rabbit diet and it is more economical at 40% replacement level.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

This study was conducted to determine the growth performance and correlation matrix ofSavanna Brown goats fed enzyme treated sawdust diets managed intensively. A total of thirty(30) goats weighting between 5.2 and 5.3 kg were arranged in a completely randomizeddesign. The animals were divided into five dietary Treatments (T) groups with threereplications. Treatment one (1) comprises of animals fed 0 % enzyme treated sawdust whileTreatment 2 (T2), Treatment 3 (T3), Treatment 4 (T4) and Treatment 5 (T5) comprises ofanimals fed 10, 20, 30 and 40 % enzyme treated sawdust diets, respectively. Data on growthperformance parameters, body linear measurement (height at wither, body length, chestgirth, hind leg length, fore leg length, facial length) were measured. Growth performancedata were analyzed using one way analysis of variance. The results of growth performancereveled that animals fed 20 % and 40 % had significantly highest value, these trend wasobserved in total weight gain (T3 = 4900g and T5 = 4833g), average weight gain (T3 = 50gand T5 = 49.32g), total fed intake (T3 = 2956.20 and T5 = 2709.30g) and average feed intake(T3 = 211.16g and T5 = 193.52g). However, in feed conversion ration no significantdifference was observed across all the treatment groups as the value range between 3.87 inanimals fed 40 % to 7.12 in those fed 10 % enzyme treated sawdust diet. A positive andsignificant correlation was observed between body weight and chest girth with highestcorrelations in animals fed 20 % enzyme treated sawdust (0.97). It was therefore concludedthat enzyme treated sawdust can be used in the diets of Savanna Brown goats up to 40 %replacement for maize offal for optimum performance

This study was conducted in one of the private fields in Maysan province to study the effect of adding a different level of bentonite to the lamb diets on the performance of lambs. The study included (18) male Arabi lambs weighted 24.5±1.22 kg and lasted 120 days. Lambs were taken after weaning at the age of 3 to 4 months. They were randomly divided into six groups. The diet was provided on the basis of 3% of live body weight. The diets of the trial included (A) a basic diet of 50% concentrated fodder + 50 alfalfa without any addition. (B) A plus 2% bentonite/ dry matter. (C) A plus 4% bentonite/ dry matter. Treatment (D) a diet of 100% concentrated feed + hay ad libitum (basic diet 2) and without any addition. (E) D plus 2% bentonite. (F) D plus 4% bentonite. The diet significantly affected the average final weight and total weight gain in favor of lambs fed treatment D (100% concentrated feed) with average final weight and total weight gain 46.57 and 22.11 kg, respectively. The addition of bentonite improved the rates of the rate of total weight gain is 17.71, 20.85 and 19.50 kg without adding and adding bentonite (2%) and bentonite (4%), respectively. The diet significantly affected the digestion rate of DM, OM, CP, EE, and NDF. Their digestion coefficients of 100% concentrate group were (75.98, 80.70, 80.09, 65.31 and 31.67%, respectively). 50% concentrated fodder (70.26, 71.53, 76.22, 45.47 and 27.36%, respectively).

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.
