Abstract This work aimed to compare piglet’s performance when fed DL-Methionine or Hydroxy-Methionine (OH-Met and OH-MetCa) at the requirements of sulfur amino acids (SAA) or above. 720 piglets (♀ large white*landrace x ♂ pietrain*duroc) were weaned at 28 days old (6.84 ± 1.07 kg) and randomly allocated to the experimental treatments for 42 days. The experiment was a factorial design with three Met sources (DL-Met, liquid OH-Met (acid form) or OH-MetCa under powder form) and two doses of SAA. Treatments were formulated to reach the adequate SID SAA/Lys ratio of 58% or exceeded the Spanish nutrient recommendations in SAA by 25% (0.79% SID SAA/Lys). Each treatment was replicated 12 times (6 pens of males and 6 pens of females). Growth performance was measured and data was analysed by mixed-effects models (R Core Team). The body weight was neither affected by SAA level, nor by the Met sources. The daily weight gain (DWG) was not affected by the dietary treatments from 0 to 21 days; whereas the feed conversion ratio (FCR) was significantly (P=0.01) improved when the SAA level was increased by 25% (1.272 and 1.184) due to the decreased feed intake (P=0.03). Significant interactions were found between the Sex and the SAA level for DWG (P = 0.04) and FCR (P = 0.03) from 0 to 21 days. From day 21 to 42 and from day 0 to 42, no performance criteria were different in all dietary treatments. For all criteria of performance, the three Met sources exhibited a similar response. These results confirmed that Met sources are equivalent in piglets.

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.

Fourteen protein systems coded by 15 structural loci were typed by horizontal electrophoresis to determine possible associations betweem the protein phenotypes and productive traits in Landrace (N=109), Largo White (N= 116) and Duroe (N=57) pigs, reared in Southern Brazil. Signiticant associations between protein phenotypes and production traits were detected. The most consistent interaction were observed between two protein systems (phosphogluconate dehydrogenase - Pgd and Hemopexin -Hpx) and at least one of the four performance variables considered. In Duroc breed, the Pgd phenotypes were associated with daily weight gain (P < 0.01), feed conversion ratio (P < 0.01) and selection index (P < 0.001), while in Landrace significant associations were observed only with feed convertion ratio (P < 0.05). The Hpx phenotypes were associated with daily weight gain (P < 0.05) and backfat thickness (P < 0.05) in Large White and with this last variable (P < 0.01) and selection index (P < 0.05) in Duroc pigs. Since these results had not been reported previously, turther studies are need to confirm these associations.

The influence of increasing dietary concentrations of copper (Cu), together with low or high inclusion levels of zinc (Zn), on performance, faecal mineral concentrations and the mineral status of the body was examined in 216 Large White × Landrace pigs (initial weight 27 kg, final weight 107 kg). The base diets were supplemented with combinations of 0, 10, 30 or 50 mg/kg Cu and 40 or 80 mg/kg Zn in the proteinate amino acid chelate form (organic), according to a factorial arrangement of treatments. A control treatment containing levels of Cu and Zn similar to the high organic treatment in the form of sulfate (inorganic) was also included. Blood and faecal samples were collected on Days 21 and 49 of the experiment and tissue samples immediately after slaughter. Across the entire growing and finishing phases, no significant treatment differences (P > 0.05) occurred in pig daily gain or feed intake, although feed conversion ratio was improved (P < 0.05) by the inclusion of proteinate amino acid chelate. Copper and Zn concentrations in faeces were in direct proportion to their inclusion level in the diet. Blood and tissue mineral concentrations were within normal physiological ranges in all treatments. Results showed that reducing Cu and Zn in grower–finisher diets from 50 to 0 mg/kg Cu and from 80 to 40 mg/kg Zn reduced faecal Cu and Zn concentrations by 90 and 40%, respectively, without compromising pig growth. However, when Cu was supplemented at 0 mg/kg, storage of Cu in the liver approached marginal levels, suggesting that some added dietary Cu is needed in grower–finisher diets, especially for pigs reared in commercial conditions.

Different Levels

The influence of dietary L-carnitine and lysine (Lys)-methionine (Met) levels on productive performance, haematology and triiodothyronine hormone levels of broilers was investigated. Dietary treatments included different L-carnitine (0, 50 and 100 mg/kg) and Lys-Met (0%, 10% and 20% over National Research Council (NRC) (1994) recommendation levels), under a 3 × 3 factorial design arrangement. From the findings, the body weight (BW) gain, feed intake and feed conversion ratio (FCR) of broilers were significantly (p < 0.05) influenced by dietary treatments in the different growing stages. Conversely, carcass yield and organs did not differ (p > 0.05) among treatments, whereas meat-cuts varied significantly when broilers were fed experimental diets. Moreover, the dietary inclusion of the highest levels of amino-acids (L-carnitine (100 mg/kg) and Lys-Met (+20%)) produced a reduction (p < 0.05) of blood uric acid, also leading to the highest triiodothyronine (T3) hormone levels. Based on the obtained results, it can be concluded that the combination of extra levels of L-carnitine associated with Lys-Met positively influenced the performance traits in broiler chickens.

A study was carried on 24 piglets (Large White York Shire × Desi) of an average initial weight of 20 kg of three gender groups, barrows, boars and gilts consisted of eight pigs each, of comparable body weight fattened from 20-48 kilograms (growing) to 49-96 kilograms (finishing) to see the effect of gender on growth performance, nutrient utilization and carcass traits. When comparing feed intake at the growing stage, gilts consumed significantly more (P less than 0.05) feed than boars and barrows. There was no significant difference in average daily weight gain among barrows, boars and gilts in growing and finishing stage. Gilts had significantly higher (P less than 0.05) feed conversion ratio than boars in growing period and barrows in finishing period. Nutrient digestibility was similar except crude protein among groups. Fasting weight and weight after bleeding was significantly lower (P less than 0.05) in gilts with nonsignificant difference between barrows and boars. Sex has no significant effect on evisceration weight, dressing percentage and carcass length in pigs. Carcass backfat of barrows was significantly thicker (P less than 0.05) than that of boars and gilts, however, the loin eye area was significantly larger (P less than 0.05) in gilts than boars and barrows. There were no significant differences among groups concerning the proportions of ham, under cut, bacon and rib chop however, shoulder and loin percentages were higher (P less than 0.05) in gilts than boars and barrows.

The present study was designed to evaluate the effect of different levels of Lysine (Lys) on early growth, body conformation and immune response of three varieties of Aseel chicken. Five hundred and forty day old chicks were used in this experiment. Experimental treatments were three verities i-e Mianwali (MW), Peshawari (PW), and Lakha (LK) and three level of Lys i-e L1 (1.35), L2 (1.30) and L3 (1.25%). Treatments were arranged in factorial arrangement under randomized complete block design (RCBD) with sex as block. Each experimental group was replicated 6 times with 10 birds in each. Results indicated that PW variety showed a greater feed intake (FI) throughout the experiment, however, body weight gain (BWG) and feed conversion ratio (FCR) were remained unchanged within varieties. Lower FI was observed in birds fed diets containing 1.35, 1.30% digestible Lys. Birds fed diets containing 1.35, 1.30% digestible Lys showed higher (BWG (P less than 0.05) and improved FCR (P less than 0.05). Mianwali variety with 1.35, 1.30% digestible Lys diets, showed (252.0±17.4 and 251.4±7.15; 2.37±0.17 and 2.35±0.06) an interaction for BWG and FCR. Birds fed amino acid dense diets depicted improved body conformation traits (length of body, drum stick, shank keel bone, circumference of drumstick and shank, wing spread and breast width), whereas immune responses (were not influenced by the dietary treatments. In conclusion, it was found that 1.30% digestible Lys level with ideal amino acid ratio was better for improving early BWG and FCR in Mianwali Aseel.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

A study was conducted at the Abubakar Tafawa Balewa University (ATBU) Research and Teaching Farm between December and May 2006 to determine nutrient intake, digestibility and growth performance in Yankasa rams fed urea-treated (UTRS) and untreated rice straw (URS) with supplementation. Thirty-two (32) Yankasa rams with an average weigh of 17.5kg, and aged 1.5 to 2 years old were alloted to eight (8) dietary treatments with four (4) rams per treatment in a 2 x 4 factorial design. The two basal feeds were urea0treated rice straw (UTRS) and untreated rice straw (URS). The supplements were maize bran (MB), MB + sun-dried poultry litter (MB + SDPL), MB + ensiled poultry litter (MB+ EPL) and MB + cotton seed cake (MB + CSC). Total dry matter intake (TDMI), daily basal feed intake (DBFI) were significant (P<0.05) across dietary treatments. Animals on supplements MB and MB+CSC for both UTRS and URS recorded the lowest and highest DBFI. The digestible crude protein intake (DCPI) and digestible organic matter intake (DOMI) were high for rams on UTRS and the values ranged from 17.72 to 28.36g/d and 288.81 to 482.66g/d for DCPI and DOMI respectively. Nutrient digestibility was improved by treatment of straw and supplementation. However, crude protein digestibility was similar for animals fed URS but, significantly (P<0.05) lower compared to those fed UTRS which were also similar across supplements. Average daily weight gain ranged from 53.58 to 91.18g/d across dietary treatment with animals on supplement MB recording the lowest (53.58 and 61.43g/d for URS and UTRs respectively) and those fed supplement MB+CSC the highest (81.38 and 91.18g/d fro URS and UTRS respectively) irrespective of straw treatment. Feed conversion ratio (FCR) was least for animals on supplement MB+CSC for both URS and UTRs, indicating that this supplement (MB+CSC) influenced feed utilization more positively. From the results of this trial, it may be concluded that straw treatment and/or supplementation can enhance crop residue utilization by sheep. however, mixed supplements especially MB+CSC were more efficient in enhancing the utilization of the straw and consequently animal performance.

Poultry farmers who rely on commercial feeds sourced from the market always suffer some forms of financial loss due to sub-standard nature of such feeds. The normal practice is to formulate a balanced diet and compound the feeds with good quality ingredients. These conditions are not always within the control of the farmers who rely on buying finished feeds from the market. There is dearth of information on the quality of these common types of feedsin the market with the aim of recommending the best to the farmers. This study was therefore, carried out to examine the response of broilers to three commercial feeds at the starter and finisher phases. One hundred and eighty 1-day-old unsexed Marshal broilers at three replicates of twenty birds each were used for the study; and lasted for eight weeks. Feed and water were supplied ad libitum. The performance, carcass, haematological and biochemicalparameters of the experimental birds were measured. The three diets were tagged Diets 1, 2 and 3 each representing a treatment. The average final live weight (AFLW), daily weight gain (ADWG), daily feed intake (ADFI) and feed conversion ratio (FCR) were significantly (P < 0.05) influenced by the feed types (dietary treatments). The highest AFLW (758.37g/b) was obtained for broiler starters fed Diet 2 compared to 689.60g/b (Diet 1) and 263.37g/b (Diet3). The ADWG followed the same trend with birds fed Diet 2 having the highest value (25.67g/b) compared with 23.22g/b (Diet 1) and 8.00g/b (Diet 3). The ADFI (starters) were 72.88, 80.36 and 62.20g/b respectively for birds fed Diets 1, 2 and 3. The corresponding ADFI (g/b/d) for the finishers were 133.63 (Diet 1), 177.53 (Diet 2) and 58.57 (Diet 3); and ADWG (g/b/d) 42.49 (Diet 1), 51.79 (Diet 2) and 8.57 (Diet 3). Diet 2 gave the best performance in terms of weight gain, followed by Diet 1 and Diet 3 in that order for the finishers. However, the average cost per kg weight gain of the birds for the 2 phases were ? 307.88 (Diet 1), ? 309.29 (Diet 2), and ? 582.74 (Diet 3). All the carcass (live weight, bled weight, plucked weight, eviscerated weight, dressed weight and abdominal fat); and internal organs such as heart, lung, liver, kidney, pancreas, intestine and proventriculus were significantly (P < 0.05) affected by dietary treatments. The RBC, Hb, Basophils, total protein, albumin and globulin differed significantly (P < 0.05) across the diets. It can be concluded that birds fed Diet 1 gavethe best overall economic, carcass, haematology and serological performance. Commercial Diet (feed) 1 is therefore recommended for broiler farmers.

The study assessed the effect on performance and serum metabolites of ninety grower pigs fed extruded full-fat soyabean meal (ESBM) and cottonseed cake (CSC) as partial (-50%) and whole (100%) replacement  for groundnut cake (GNC) in practical-type  diets over 12 weeks feeding period. Ninety Large White X Landrace pigs average initial live weight of 30.50+1.4kg were randomly assigned to five dietary treatments and each treatment had three replicates The diets were iso-nitrogenous and iso-caloric. The ESBM in the diets showed an  improvement in average daily weight gain and eed conversion. Diet in which there was 50%replacement of GNC with ESBM gave the best  result (P<0.05). However, general trend showed a numerical increase with levels of ESBM and CSC in the diets. Serum albumin  and cholesterol levels were significantly (P<0.05) reduced by inclusion of extruded full-fat soyabean meal, and CSC while serum creatinine level was increased.
