Abstract ABSTRACT Background: A study was carried out in Loma district of Southern part of Ethiopia that aimed to determine the effects of supplementation of graded levels of sweet potato vine silage on growth performances of grazing indigenous goat breeds. Loma district, the potential area for sweet potato production, that they practiced feeding sweet potato for animal feed shortage especially during dry season in the study area. Two hundred Sixteen indigenous yearling male local goats (16.3±0.4kg) were randomly selected for on-farm feeding trial. The goats were blocked into four groups of fifty four animals based on their initial body weight. Dietary treatments were randomly assigned to each animal in the groups. Animals which were assigned randomly in each block were given to farmers. The treatment comprised of grazing alone as treatment 1, grazing+78 g dry matter sweet potato silage as treatment 2, grazing +156 g dry matter sweet potato silage as treatment 3, grazing + 234 g dry matter sweet potato silage as treatment 4. Results: The highest dry matter contents (89.7%) were observed in final trial periods compared to initial and mid-term of trial periods. The average daily gain for Treatment 4 was higher (P<0.05) than those goats in Treatment 1 and Treatment 2. The weight gain for Treatment 3 and Treatment 4 were similar (P>0.05). About 96.7% of the respondents produce sweet potato. Conclusions: In the current feeding trial study results indicated that, the increased supplementation of sweet potato vine silage revealed increased performance of grazing local goats. Intake of dry matter increased from 78% to 234% with increasing levels of sweet potato vine silage supplementation. There was higher average daily gain for the supplemented group (60, 80 and 97g/head/day in Treatment 2, Treatment 3 and Treatment 4, respectively) than non-supplemented ones (34.2g/head/day). Therefore, from these findings it is concluded that supplementation of sweet potato silage favors better growth rate however we need to work on improving the productivity of sweet potato and improve benefits of feeding to goats.

Potato steam peel is a by-product of the production of frozen french fry potatoes. As produced, it typically has 14% dry matter with 15% crude protein and 6% ash (dry matter basis) and a pH of 5.8. The starch is partially denatured and there is no proteolytic enzyme inhibitor activity. The feeding value of steam peel for pigs was evaluated through chemical analyses, a digestibility trial and a feeding trial. Its digestibility (%) by pigs was found to be dry matter 81.1 ± 2.8, crude protein 61.3 ± 3.7, organic matter 82.4 ± 3.0 and energy 76.8 ± 6.0. In the feeding trial carried out on a commercial hog finishing farm, feed consumption was markedly reduced when the steam peel was included at over 30% of the ration dry matter at the start of the trial. The inclusion of steam peel at 15, 20 or 25% of the ration dry matter reduced the average daily gain and feed efficiency (P < 0.05). However, it was concluded that potato steam peel can be used at up to 25% of the diet for growing fattening pigs with little detrimental effect on the level of animal performance.

The effects of supplementing feedlot diets with ionophores and breed type were assessed on growth rate and carcass characteristics in hair lambs. Twenty four intact males, 12 Pelibuey × Dorper (PDo) and 12 Pelibuey × Damara (PDa) lambs, 17.9 ± 3.7 kg initial weight, were housed in individual pens for a 60-d feeding trial. The lambs were assigned randomly into four diets: control without additives (C); 25 µg/g monensin (M); 28 µg/g salinomycin (S); 28 µg/g S for 20 d, and 25 µg/g M for the next 40 d (SM). Each diet was supplied to six lambs. Data were analyzed as a randomized complete block design in a 4 × 2 factorial arrangement, with four diets and two breed types of hair lambs (PDo and PDa). All diets were formulated to contain 14% CP and 2.6 Mcal ME/kg dry matter. At the end of the feeding trial carcass images were recorded in the last intercostal space (12th and 13th ribs) using ultrasound equipment to measure the Longissimus dorsi muscle area and subcutaneous fat (SF). The average daily gain (ADG), daily dry matter intake, feed:gain ratio, subcutaneous fat and Longissimus dorsi area were not affected by ionophore supplementation.. The Pelibuey × Dorper group tended to show better average daily gain than Pelibuey × Damara (262 g/d and 235 g/d, respectively). Daily dry matter intake, feed:gain ratio and subcutaneous fat were not affected by breed type. The Pelibuey × Dorper lambs had greater Longissimus dorsi area (16.74 cm²) than the Pelibuey × Damara (14.29 cm²) lambs. The growth rate was not influenced by the inclusion of ionophores. Pelibuey × Dorper lambs showed better average daily gain and carcass characteristics than Pelibuey × Damara lambs.

This research aimed to determine the productivity of livestock. Feed availability in the dry season is one of the causes low productivity of livestock. Calliandra calothyrsus (C. calothyrsus) and Indigofera sp. are leguminosae plant that resistant to drought and could produce high productivity. Both can be used as a sustainable animal feed and reduce production costs. The animal used was weaned male sheep. The method used was Completely Randomized Design (CRD), with six treatments (P0 : 70% Grass + 30% Concentrate, P1 : 70% P. Grass + 15% Concentrate + 15% C. calothyrsus, P2 : 70% Grass + 15% Concentrate + 15% Indigofera sp., P3 : 70% Grass + 30% C. calothyrsus, P4 : 70% Grass + 30% Indigofera sp., P5 : 70% Grass + 15% C. calothyrsus + 15% Indigofera sp.) and four replication. The observed variables were dry matter consumption, average daily gain (ADG), and feed conversion. The results showed that the used of 15% C. calothyrsus and 15% Indigofera sp. was more efficient. The highest value of dry matter consumption (P<0,05) and average daily gain (P>0,05) obtained P5 treatment, respectively 508,80 g/day and 45,36 g/day, while the lowest value of feed conversion (P>0,05) obtained P0 (11,69) which was not significantly different with P5 (11,75). Keywords: Calliandra calothyrsus, Indigofera sp., weaned male sheep, the productivity of livestock

Abstract Background: The use of antibiotics as supplements in animal feed is restricted due to possible health hazards associated with them. Consequently, there is increasing interest in exploiting natural products as antibiotics with no detrimental side effects. In this study, we examined the effect of Astragalus membranaceus root (AMT) supplementation on dry matter intake, growth performance, rumen fermentation and immunity of Tibetan sheep. Materials and methods: Twenty-four male Tibetan sheep (31 ± 1.4 kg; 9 months old) were assigned randomly to one of four dietary treatments with different levels of AMT: 0 g/kg, 20 g/kg, 50 g/kg and 80 g/kg dry matter (A 0 , A 2 , A 5 and A 8 , respectively) in addition to their basal diets. A 0 acted as a control group and measurements were recorded over a 56-d feeding period. Results: Sheep fed with AMT had a higher average daily gain (ADG) and a lower feed:gain ratio (F:G) than controls ( P < 0.001). Rumen concentrations of NH 3 -N ( P < 0.001), total volatile fatty acids (TVFA) ( P = 0.028), acetate ( P = 0.017) and propionate ( P = 0.031) in A 5 and A 8 were higher than in A 0 . The addition of AMT in the feed significantly increased serum antioxidant and immunity factors of the sheep and increased the concentrations of serum interleukin, immunoglobulin and tumour necrosis factor-α (TNF-α) ( P = 0.010). Conclusions: We concluded that AMT can be used as a feed additive to improve growth performance and rumen fermentation and enhance the immunity of Tibetan sheep. Some responses exhibited a dose-dependent response, whereas other did not exhibit a pattern, with an increase in AMT. The addition of 50 g/kg and 80 g/kg AMT of total DMI showed the most promising results.

This study was conducted to determine the accuracy of average daily gain (ADG) predictions based on digestible energy (DE) estimated from acid detergent fiber (ADF) and on the nutrient requirements of beef cattle when applied to growing cattle fed silages of contrasting digestibilities with or without barley. A feeding trial was conducted with 45 Charolais × Simmental calves fed either a control silage (early cut, E) with no barley or two other silages (medium cut, M; late cut, L) fed with (M + barley and L + barley) or without 60% dry-matter (DM) basis rolled barley in the diet. Total dry-matter intake (DMI) of diet E was higher (P < 0.05) than that of diets M and L. The addition of barley in diets M + barley and L + barley led to an increase (P < 0.05) in total DMI. ADG of steers fed diet E was higher (P < 0.05) than that of steers fed diets M and L but lower (P < 0.05) than that of steers fed diets M + barley and L + barley. A digestion trial was conducted concurrently, using five steers fed at 90% ad libitum. The apparent digestibility values of the DM for the five diets tested were (E) 68.5, (M) 60.8, (L) 56.8, (M + barley) 70.8 and (L + barley) 70.1%. Gains predicted when forage DE was estimated from ADF or determined in vivo were, respectively, 57 and 92.6% of observed values. When barley–supplemented diets were studied separately, it was apparent that most of the prediction error was due to the inability to predict forage DE from ADF. Further research is needed to develop methods to accurately predict the energy content of forage silages grown in Canada. Key words: Energy, forages, silages, cattle

Fumonisin contamination in corn is an emerging issue in animal feed production. Fumonisin disrupts the metabolism of sphingolipids and reduces growth performance. This experiment was conducted to determine the effect of feeding fumonisin-contaminated corn on growth performance and sphinganine (SA) to sphingosine (SO) ratios of 9 to 28 kg pigs. A total of 350 pigs, were used with 5 pigs/pen and 14 pens/treatment. Dietary treatments contained fumonisin-contaminated corn (50 mg/kg of fumonisin B1 + B2) blended with low fumonisin corn (10 mg/kg of fumonisin B1 + B2) to provide dietary fumonisin concentrations of 7.2, 14.7, 21.9, 32.7, and 35.1 mg/kg. From day 0 to 28, increasing fumonisin concentration decreased (linear, p < 0.001) average daily gain, average daily feed intake (linear, p = 0.055), and gain:feed ratio (linear, p = 0.016). Although these response criteria tested linear, the greatest reduction in performance was in pigs fed with 32.7 and 35.1 mg/kg of fumonisin (B1 + B2). Increasing fumonisin concentration increased the serum SA:SO ratio (linear, p < 0.001) on day 14 and 28. In summary, for 9 to 28 kg nursery pigs, increasing fumonisin linearly decreased average daily gain and gain:feed ratio. However, despite the linear response, diets containing up to 21.9 mg/kg of fumonisin did not have as dramatic a decrease in growth performance as those fed more than 32.7 mg/kg. Further research is warranted to determine the effect of fumonisin concentrations between 21.9 and 32.7 mg/kg.

AbstractA total of 384 piglets from a three-way cross Yorkshire ♂ × (Finnish Landrace ♂ × Dutch Landrace♀) ♀ in the live-weight range of 11 to 25 kg were used in a feeding trial. The effect of supplementary microbial phytase from Aspergillus niger var. Van Tieghem on performance (average daily gain (ADG), average daily food intake (ADFI) and food conversion ratio (FCR)) and apparent digestibility of total phosphorus (P), in comparison with a non-supplemented basal diet or a diet supplemented with one or two levels of monocalcium phosphate (MCP), were studied.The piglets were allotted to 12 blocks. Within each block, four experimental diets were offered ad libitum for a period of 4 weeks i.e. (1) basal diet; (2) basal diet + 1·0 g P, from MCP per kg diet; (3) basal diet + 1·9 g P, from MCP per kg diet; and (4) basal diet + 1450 phytase units (PTU) per kg diet. The diets, with added chromium III oxide as a marker, were cold pelleted without steam at a temperature not above 60°C to avoid a possible inactivation of the phytase. In all diets the ratio calcium: digestible P was intended to be constant.Adding 1450 PTU of Aspergillus niger phytase enhanced the apparent digestibility of P by proportionately 0·216 when compared with diet 1 and by proportionately 0·100 compared with diet 3. In addition, significantly higher ADG and ADFI and better FCR were noted in pigs receiving supplementary microbial phytase than in pigs on any other treatment. The content of digestible P of the diet with added phytase, however, zvas between the two levels of the diets with added MCP.

SUMMARYA total of 70 Nellore bulls (18 ± 3 months of age) were used to determine the effects of crude glycerine (CG) replacing starch- v. fibre-based energy ingredients in low (LC; 0·40 concentrate) or high concentrate (HC; 0·60 concentrate) – on a dry matter (DM) basis – on DM intake (DMI), methane emissions and growth. Ten bulls were slaughtered (reference group) to obtain the carcass gain (CrG). The 60 remaining bulls (374 ± 24·5 kg) were allocated to a 2 × 3 factorial arrangement (two concentrate levels, LC or HC; and three feeding regimes, FR). The FR were: CO – without CG and maize as an ingredient of concentrate; CGM – inclusion of CG (0·10 of DM) replacing maize in the concentrate; and CGSH – inclusion of CG (0·10 of DM) replacing soybean hulls (SH) in the concentrate. Bulls fed LC or HC had similar DMI (kg/d) and growth. The DMI and average daily gain (ADG) were similar among FR. Concentrate level and FR tended to interact for methane emissions (g) per kg DMI. Bulls fed CGM had a greater G : F (g CrG/kg DMI) than those fed CO or CGSH diets. Increasing dietary concentrate (0·40–0·60) did not affect intake, methane emissions, or growth. Inclusion of CG in diets to replace SH in LC diets tended to decrease methane emissions from animals. When CG replaces SH in the diets, CrG and G:F (g CrG/kg DMI) are decreased compared with bulls fed CGM.

Thirty-two large-frame crossbred steers (443 ± 5 kg) were used to determine the nutritive value of cracked corn, rolled barley, rolled oats and rolled wheat in finishing diets for beef cattle fed medium-quality grass hay. Diets contained about 54% grains, 40% grass hay and 6% of a supplement of minerals, vitamins and lasalocid. Total daily dry matter (DM) intake ranged from 9.52 to 10.24 kg, average daily gain from 1.09 to 1.17 kg and gain to feed ratio from 0.113 to 0.121, but these values were not statistically different (P > 0.05). Apparent digestibilities of DM and energy of steers receiving the oats diet were lower than those of steers receiving the wheat diet (P < 0.05), the other diets having intermediate values. Apparent digestion coefficient of protein was higher for the oats diet (P < 0.05) than for other diets. Acid detergent fiber digestibility was higher (P < 0.05) and starch digestibility was lower (P < 0.05) in steers receiving corn than in those receiving barley, oats or wheat. The results indicate that nutritive value of all diets was similar. Key words: Grains, fattening steers, digestibility
