Several approaches have been adopted to utilize body weight and linear body measurement in predicting carcass composition in goats. However this information on prediction of carcass composition from body weight and linear body measurements is limited for goats raised in the southern region of Nigeria. A study was conducted to determine the relationship between live body weight, linear body measurements and carcass characteristics of West African dwarf (WAD) goats and Red Sokoto (RS) goats. Live body weight (LBW), Heart girth (HG), Body depth (BD), Rump height (RH), Height at wither (HW) and Body length (BL) were the linear body measurements. Neck, hind limbs, head, slaughtered weight; empty carcass, fore limb and warm carcass were measured for carcass traits. Internal offals weighed were spleen, liver, lung, heart, kidney and empty gut. Twenty West African Dwarf goats ( 10 males and 10 females weighed 15.00 ± 0.10kg and 14.25 ± 0.50kg respectively) and twenty Red Sokoto ( 10 males and 10 females weighed 21.80 ± 0.67kg and 20.50 ± 0.12kg respectively)between the ages of 2-3 years were used for this study. Data obtained were analyzed using t-test, correlation analysis and multiple regressions. Results showed that the mean live body weight of WAD goats and RS goats were 14.63±0.46 and 21.13±0.36, respectively. Average linear body measurements of WAD and RS goats showed significant (p<0.05) differences in all the parameters except BL with RS goats having higher values . Average carcass traits of the two breeds of goats were significantly (p<0.05) different in hind limb, slaughtered weight and fore limb weight in favour of RS goats. Internal edible offal weight of both breeds differed significantly (p<0.05) in spleen, heart and kidney. There were significant positive correlations (P<0.001) between live body weight and linear body measurements in both breeds Strong and positive significant correlation (P<0.05) were also observed between 2 linear body measurement and most of the carcass traits measured. The highest R values in both breeds of goat were obtained when all the body measurements were included in the regression equations. It can be concluded that the correlation between linear body measurements can serve as selection criteria in improving carcass traits for better meat production. Moreso, carcass traits could be estimated more accurately by combination of two or more linear measurements. \u0000  \u0000  \u0000Les chèvres sont élevées principalement pour la viande au Nigéria, leur poids corporel et leurs dimensions corporelles sont d'importants traits de carcasse intéressants.

Farmers under semi-intensive system commonly offer feed supplements to their animals in the morning before grazing fibrous grasses all day. However, results of rumen degradability studies suggested that this system should be the opposite. This study was designed to investigate the effect of changing the sequence and interval of feeding concentrate supplement (CS) and roughage on performance of Yankasa weaner rams. A 90-day feeding trial was conducted using twenty eight 5-6 months old Yankasa weaner rams with average body weight of 14.96 ± 1.10 kg. The rams were randomly assigned to four treatments (CB1: CS fed 1 h prior to feeding grass hay (GH); CB2: CS fed 2h prior to feeding GH; GB1: GH fed 1 h before feeding CS; and GB2: GH fed 2 h before feeding CS) using a 2x2 factorial arrangement in a randomized complete block design (RCBD). The rams were fed woolly finger grass (Digitaria smutsii Stent) hay and CS at the rate of 2.4% and 1.6% of body weight, respectively, and offered water ad libitum. Blood collection was done at four weeks interval pre- feeding and 4 h post- second feeding. Rumen fluid was collected pre- feeding and 3 h post-second feeding during the last week of feeding trial. Parameters measured include dry matter intake (DMI), total weight change, Average daily gains (ADG), Total volatile fatty acids (VFAs), ruminal pH values, and Blood creatinine levels. DMI was significantly (P < 0.05) affected by the interval of the feeding. The total weight change of GB2 and CB2 rams was significantly (P < 0.01) higher than that of CB1 and GB1 rams. ADG among treatments were affected (P < 0.05) by feeding interval. VFAs and ruminal pH values of the rams 3 h post-feeding were affected (P< 0.05) by the interval of feeding CS and GH. Pre-feeding blood creatinine levels and 4 h post-feeding, were also significantly (P< 0.05) affected by interval of feeding GH and CS. It is concluded that, even though, feed intake and growth rate of Yankasa rams were not markedly affected by the sequence as much as interval of feeding CS and GH, the GB2 rams had higher ADG and better feed efficiency. \u0000  \u0000  \u0000  \u0000La production et la productivité des petits ruminants en Afrique de l'Ouest humide sont limitées par des contraintes alimentaires, qui sont en grande partie dues à une utilisation non stratégique et à une combinaison des ressources alimentaires disponibles pour développer un système d'alimentation de production efficace, plutôt qu'à une indisponibilité absolue.

Hence, this study examined the fermentation characteristics and performance of West African dwarf (WAD) sheep fed graded levels of soybean cheese waste (SBCW). Three diets were formulated at 0%, 10% and 20% levels of SBCW respectively as D1, D2 and D3. Eighteen WAD sheep averaging 14 kg were randomly allocated to the dietary treatments for 102 days. The crude protein (CP) content of the diets varied significantly (p < 0.05) with CP of D1 being lowest (12.18 %) and highest in D3 (17.75 %). The gas volume produced at the end of 24 hrs incubation for D3 was lower than in D1 and D2. The methane volume produced was least in D3 and highest in D1. The calculated organic matter digestibility (OMD), metabolizable energy (ME) and short chain fatty acids (SCFA) values were similar except for D3 which had higher OMD than D1 and D2. Daily dry matter intake (DDMI) of WAD sheep fed D3 was highest compared to other diets. A similar trend was observed in average daily weight gain (ADWG). D3 had the least cost per kg of diet among the others. From the results obtained, it was observed that diet D3 appeared to be the best and economically viable for sheep production. \u0000  \u0000  \u0000  \u0000La pénurie d'aliments et le coût élevé des ingrédients alimentaires conventionnels dans les tropiques et la vive concurrence entre l'homme et les autres animaux d'élevage ont nécessité la recherche de ressources alimentaires alternatives bon marché, disponibles à tout moment mais non toxiques pour les ruminants afin d'améliorer leur productivité. Par conséquent, cette étude a examiné les caractéristiques de fermentation et les performances des West African Dwarf (WAD) sheep nourris avec des niveaux gradués de déchets de fromage de soja (DFS).

Thus, a 56 day feeding trial was conducted to determine the effect of garlic bulb meal (GBM) as a natural feed additive on growth performance, blood profile, carcass characteristics and cost benefit of broiler chicken. A total of 150, one day old broiler chicks, were randomly allotted into four dietary treatments with three replicate of 12 birds each in a completely randomized design. Four diets were compounded to contain 0, 1, 5, 10 g/kg GBM respectively. Parameters assessed were feed intake, weight gain, feed conversion ratio, haematological, serum biochemical indices, carcass and cost benefits. Results showed that, GBM based diet significantly (P<0.05) influenced the feed conversion ratio across the dietary treatments as birds in D recorded the lowest FCR (1.64) values. The GBM supplementation groups had improved haematological parameters across the dietary treatments most especially in PCV (23.33 - 36.00%), Hb (7.66– 12.06 g/dL) and RBC (2.15 – 3.69 × 103 iu/L) values. Serum biochemical indices of broiler chicken observed in this study increased across the dietary treatments as GBM inclusion levels increased. Birds fed 5g/kg (13.66 and 4.10 g/L) and 10g/kg (14.13 and 4.23 g/L) GBM based diet recorded the highest total protein and globulin values. GBM supplemental diet had no (P>0.05) effect on carcass characteristics of broiler chicken except the spleen. The spleen (0.09 – 0.23%) of the experimental birds increased across the dietary treatments as GBM inclusion levels increased. It was therefore concluded that the garlic powder supplemented at 1g/kg in the diet of broiler chicken supported optimal performance of the birds. \u0000  \u0000  \u0000  \u0000Les scientifiques avicoles ont été chargés d'opter pour des compléments alimentaires naturels pour développer des aliments idéaux, sûrs et rentables par rapport aux aliments synthétiques.

Consequently, there has been search for potential alternatives to AGPs. Probiotics and prebiotics have been suggested as useful dietary means for compensating the loss in productive performance when AGPs are removed from poultry diets. The study aimed at evaluating the combined effect of dietary probiotics and prebiotics on bird growth performance as an alternative to antibiotic growth promoter. Six hundred day old chicks were used for this study and were intensively managed. The chicks were randomly assigned into five treatments in a complete randomized design and administered as 0g, 1g, 2g, 3g of Poultrystar® Sol with oxytetracycline as positive control. Growth parameters (total feed intake, weight gain and FCR) were studied. Collected data were subjected to one-way Analysis of variance and significant differences in the means were separated using Dunnet® test at 95% probability. Result showed a significant (p<0.05) influence of Poultrystar® Sol on  weight gain, feed intake, FCR and cost of total feed intake. The birds on 3g Poultrystar Sol had better weight gain (1276.20g), FCR (0.74) and less cost of total feed intake (N123.70) when compared with birds on 0% inclusion, oxytetracycline and birds on other levels of Poultrystar® Sol.

At 10 weeks of age, higher significant (P<0.05) mean SL (5.24± 0.06 cm) and DL (10.44± 6.92 cm) from IBxNa; BG (16.74 ± 0.20 cm) and BW (20.59± 0.18 cm) from IBxN; KL (7.01± 0.07 cm) from NxIB; BL (26.78±1.42 cm) from FxIB and WL (13.72± 0.09 cm) from IBxF genotypes were recorded. The SL, DL, KL of IBxNa; BW of FxIB and BL of NaxIB genotypes had higher significant means at 20 weeks. The NxIB and IBxN genotypes which depicted outstanding growth performace at 2-10 weeks should be selected for improvement of fast growing chcikens while IBxNa, FxIB, NaxIB genotypes which recorded better performance at 20 weeks may be considered for development of egg-type chickens. \u0000  \u0000  \u0000  \u0000Les poulets indigènes du Nigéria sont connus pour une faible productivité en raison de leur état génétique non amélioré.

This is due to high cost, which makes it unaffordable to the majority of the small-scale farmers. These farmers are unaware that the lick blocks can be formulated with the non-conventional local resources. This experiment was conducted to substitute the conventional molasses with nonconventional local resources, assess the cost of compounding different Protein Lick Blocks (PLB) and determine their acceptability by Yankasa Rams in 90 days. Three varieties of PLB were compounded using the conventional molasses and non-conventional sweet potatoes and mango pulps and designated into four treatments; T1, T2, T3 and T4. While T1 was a control group and contained only basal feed with no PLB, T2, T3 and T4 contained basal feeds and molasses, potatoes and mango pulps lick blocks respectively. A total number of 16 rams divided into four were assigned into each treatment. The parameters used for this study were feed intake rate and the cost of compounding the non-conventional lick blocks. The results showed that T2 was more acceptable, recording a higher daily intake of lick block of 110g, followed by T4, then T3 recording 83g and 75g respectively. On the economic aspect, Rams in T2 were found to consume more, recording higher daily expenditure of ? 29.26, followed by T3 then T4, with daily expenditure of ? 15 and ? 10 respectively. This experiment shows that, sweeter ingredients were more palatable than the less sweet ones, hence consumed more. Economically, although protein lick block containing mango pulp was consumed more than that of potatoes, it was found to be cheaper than all the other two protein lick block. \u0000  \u0000  \u0000  \u0000  \u0000Les propriétaires de bétail traditionnels ont récemment été découragés d'incorporer les blocs à lécher conventionnels disponibles sur le marché aux régimes alimentaires du bétail.

Breast girth (BG), body length (BL), wing span (WS), wing length (WL), and thigh length (TL) of Nigerian local turkeys are the best discriminating variables in differentiating the birds, according to recent studies. There are also significant physical differences between the sexes, as well as differences in trait associations within each sex. Genetic differences may account for the majority of morphological differences in turkeys. In developing and underdeveloped countries, discriminant analysis provides a practical analytical framework for characterizing and managing turkey's genetic resources. To fully understand the genetic variation among indigenous, crossbred, and exotic turkeys, this study should be followed up with molecular approaches. The ability to distinguish the growth traits of indigenous or native, exotic and crossbred turkeys in Nigeria using multivariate discriminant analysis could aid in the implementation of a conservation and improvement strategy for indigenous turkeys, ensuring the long-term development of animals using their genetic merits. \u0000  \u0000  \u0000Dans les zones rurales où les échelles de mesure sont chères et indisponibles, les mesures corporelles linéaires peuvent être utilisées comme prédicteurs du poids corporel.
