AbstractSeven, 3-year-old pony mares (~230 kg) were used in a cross-over study to compare the appetite, energy and nutrient digestibilities, growth rate and feeding behaviour, when a complete diet was offered ad libitum in either the original loose-chaff mix (C), or as a more convenient, milled and pelleted preparation (P). Ad libitum access to the study diet (gross energy = 17·2 MJ/kg dry matter (DM)) was attained over 2 weeks. In the following 4 weeks, groups 1 (no. = 3) and 2 (no. = 4) received pelleted and chaff-based diets respectively. Dietary forms were exchanged during week 5 and ad libitum provision continued for a further 4 weeks. Behaviour and apparent nutrient digestibilities were assessed in weeks 3 and 4 of each period. Pelleted food had a lower proportion of water (P, 0·12; C, 0·22), but relative proportions of oil (0·04), crude protein (0·08), crude fibre (0·29), neutral-detergent fibre (NDF; 0·53) and gross energy (GE) were neither altered by food processing nor time. Apparent digestibilities (DM, 0·49; GE, 0·50; NDF, 0·40 in period 1) of the pelleted and chaff-based diets were similar within periods but decreased (P 0·01) to a similar extent for both diet types (proportional changes: DM, –0·14; GE, –0·16; NDF, –0·28) in period 2. Overall, mean intakes of digestible energy (DE) for chaff-fed animals during period 1 were 0·73 (P 0·001) of pellet DE intake (DEI). Mean DEI of pellets increased (P 0·001) during period 1 to attain 1·76 (s.e. 0·25) MJ/kg M0·75 on day 25. Following transfer from pellets to chaff, DEI decreased (P 0·001) to 0·68 (s.e. 0·07) MJ/kg M0·75 by the end of period 2. In contrast, DEI of animals which progressed from chaff to pellets remained relatively constant between periods. Oestrous behaviour caused no detectable change in the appetite of individual mares. Irrespective of differences in DEI, average daily gain (ADG) in body weight and condition score (CS) did not differ between groups. Overall, mean ADG decreased (P 0·01) from 1·54 (s.e. 0·17) kg/day in period 1 to 0·26 (s.e.0·08) kg/day in period 2. Changes in body weight were associated with CS (R2 = 0·72). Each CS point represented a 53·4 (s.e. 4·8) kg gain in body weight. Chaff meals were longer (30·6 (s.e. 1·6) min, P 0·001), less frequent (23·8 (s.e. 1·4) per day, P 0·001) and associated with a lower bite rate (3·8 (s.e.0·2) per min, P 0·001) and increased chewing requirement (23 (s.e. 1·2) per bite, P 0·001), which decreased the rate of DM intake (17·0 (s.e. 0·9) g/min, P 0·0.01). Overall, chaff-fed animals spent more time feeding (0·50 (s.e. 1·3) of the time; P 0·0.01), primarily at the expense of non-feeding activity and rest. The ad libitum feeding regime enabled stabled ponies to re-establish natural feeding patterns and offers a viable alternative to meal and forage feeding. The more slowly ingested chaff form maximized time spent feeding and limited changes in DEI during the introductory period. Although CS and ADG increased over the first 4 weeks, growth and appetite returned to near maintenance values within 9 weeks in association with a decrease in dietary energy intake and nutrient digestibility.

Watermelon rind is one of the several unwanted by-products generated by restaurants, fruit juice producers and food industries in Nigeria that can be gotten rid of by using it as an energy source in broiler production. The growth performance and apparent nutrient digestibility of broilers fed diets containing varying inclusion levels of dried watermelon rind (DWMR) in replacement for wheat offal as source of energy and fibre at starter phase was evaluated. The dried watermelon rind was prepared by sun-drying fresh watermelon for three days and oven-dried at 50 ºC for 2 hours. The birds were randomly allocated to five (5) treatments (T1 – T5), each treatment had three replicates with ten (10) birds per replicate. The birds were fed varied levels of DWMR at 0 %, 25 %, 50 %, 75 % and 100 % in replacement of wheat offal to obtain five diets. Feed and water were provided ad-libitum throughout the 28 days study duration. Body weight, Body weight gain, Feed intake, Feed conversion ratio and apparent nutrient digestibility were measured. The results obtained on the growth performance shows no significant (P>0.05) difference of the growth parameters across treatments. However, there was significant (P<0.05) difference in the digestibility of Crude fibre, Ether extract, Ash, Nitrogen free extract and Total digestible nutrient across treatments. There was no obvious variation in dry matter and crude protein digestibility. The result of the total digestible nutrient was significantly (P<0.05) higher in T2 (92.90 %) than the T1 (84.99 %) which was the control diet. The crude fibre digestibility recorded in T2 (63.48%) and T1 (61.09 %) is higher than T5 (43.00 %), the ether extract digestibility of T1 (96.42 %) is higher than the other groups with the lowest in T4 (95.25 %). There was depress ash digestibility in T5 (68.30 %), lower than the other groups with the highest in T1 (82.59 %). The study therefore concluded that farmers can replace wheat offal with 25 % watermelon rind in broiler starter diet without any deleterious effect in the growth performance and nutrient digestibility.     La croûte de pastèque est l'un des nombreux sous-produits indésirables produits par les restaurants, les producteurs de jus de fruits et les industries alimentaires au Nigéria qui peuvent être débarrassés en l'utilisant comme source d'énergie dans la production de poulets à griller. La performance de croissance et la digestibilité apparente des éléments nutritifs des poulets de grillage nourris selon des régimes alimentaires contenant différents niveaux d'inclusion de la croûte de pastèque séchée (DWMR) en remplacement des aals de blé comme source d'énergie et de fibres à la phase de démarrage ont été évaluées. La croûte de pastèque séchée a été préparée par pastèque fraîche séchée pendant trois jours et séchée au four à 50ºC pendant 2 heures. Les oiseaux ont été attribués au hasard à cinq (5) traitements (T1 - T5), chaque traitement avait trois répliques avec dix (10) oiseaux par réplique. Les oiseaux ont été nourris à des niveaux variés de DWMR à 0 %, 25 %, 50 %, 75 % et 100 % en remplacement des aals de blé pour obtenir cinq régimes alimentaires. L'alimentation et l'eau ont été fournies ad-libitum tout au long de la durée de l'étude de 28 jours. Le poids corporel, le gain de poids corporel, l'apport alimentaire, le rapport de conversion des aliments pour animaux et la digestibilité apparente des nutriments ont été mesurés. Les résultats obtenus sur la performance de croissance ne montrent aucune différence significative (P>0.05) des paramètres de croissance entre les traitements. Cependant, il y avait une différence significative (P<0.05) dans la digestibilité des fibres brutes, extrait d'éther, cendres, extrait sans azote et nutriment digestible total entre les traitements. Il n'y avait aucune variation évidente dans la matière sèche et la digestibilité brute de protéine. Le résultat du nutriment digestible total a été significativement (P<0.05) plus élevé en T2 (92.90 %) que le T1 (84.99%) qui était le régime de contrôle. La digestibilité des fibres brutes enregistrée en T2 (63.48%) et T1 (61.09 %) est plus élevé que T5 (43.00 %), la digestibilité de l'extrait d'éther de T1 (96.42 %) est plus élevé que les autres groupes ayant le plus faible taux de T4 (95.25 %). Il y avait une digestibilité déprimante des cendres en T5 (68.30 %), inférieure à celle des autres groupes ayant le taux le plus élevé en T1 (82.59 %). L'étude a donc conclu que les agriculteurs peuvent remplacer les aals de blé par 25 % de croûte de pastèque dans le régime de démarrage des poulets à griller sans aucun effet délétère dans la performance de croissance et la digestibilité des nutriments.

This experiment aims to study the effects of dietary fat level during the suckling period on growth<br />performance and meat characteristics in twin lambs. Thirty pairs of male twin Hu lambs were divided into two<br />groups, namely high fat (HF) and normal fat (NF). Lambs in HF group were fed milk replacer and starter containing<br />26.89% and 5.07% of fat, whereas those in NF group, were fed milk replacer and starter containing 15.15% and<br />2.80% of fat, respectively, from eight to 60 days of age. From 60 to 120 days of age, all lambs were fed a starter feed<br />containing 2.80% fat. The results showed that lambs fed HF diet had higher body weight (12.78 kg versus 11.63 kg,<br />P = 0.020), average daily gain (162.4 g/day versus 141.1 g/day, P = 0.019), apparent digestibility of organic matter<br />(P = 0.018) and gross energy (P &lt; 0.001). No difference was observed between HF and NF group in slaughter performance<br />during eight to 60 days of age. Lambs fed HF diet had higher body weight at 120 days of age (P = 0.035).<br />However, no difference was observed in nutrient digestibility, slaughter performance or meat quality at 120 days<br />of age. In summary, HF diet in the suckling period showed long-lasting beneficial effects on the growth performance

Effect of timing of xylanase supplementation to weanling pigs and its effect on growth performance, nutrient digestibility, and fecal microbiota was investigated. A total of 128 weanling pigs [(Hampshire × Duroc) × (Yorkshire × Landrace); 6.2 ± 0.6 kg body weight (BW); weaning age: 21 d] were assigned to four treatments, with eight replicate pens and four pigs per pen. Treatments were a combination of two dietary treatments (without or with xylanase) in two periods; (period 1, days 0–14) and period 2 (days 14–42): xylanase–xylanase, xylanase–control, control–xylanase, and control–control. Fecal microbiota diversity and apparent total tract digestibility (ATTD) were determined. From days 0–14, pigs had lower (P < 0.01) BW, average daily gain (ADG), and feed efficiency when xylanase was included in the diets. The final BW (P < 0.05) and overall ADG (P < 0.02) at day 42 were greater when xylanase was supplemented from day 14 compared with supplementation from day 0. The apparent ileal digestibility and ATTD of dry matter, gross energy, nitrogen, and phosphorus were increased (P < 0.05) by xylanase. Xylanase significantly decreased (P < 0.05) the relative abundance of Veillonella spp. and tended (P = 0.08) to decrease the relative abundance of Megasphaera spp. in period 2 compared with the non-supplemented group.

Twelve adult (10 months old) castrated Korean black goats, with an average initial body weight of 24.98 ± 3.7 kg, were used in this experiment to determine their maintenance energy requirements. Dry matter intakes (g/d, p = 0.945) were not affected by energy levels, but metabolic energy intake (kcal/d, p < 0.002) and average daily gain (g/d, p < 0.001) were significantly increased at higher energy levels. Nutrient digestibility was similar in the treatments, but crude fat digestibility increased with the addition of protective fat powder (p = 0.001). The energy required for fattening the castrated Korean black goats was estimated using the correlation between metabolic energy intake per dietary body weight and average daily gain per dietary body weight. The Y-axis intercept value was calculated to be 108.76 kcal/kg BW0.75 (p < 0.05, r2 = 0.6036), which was the metabolic energy requirement for maintaining the lives of the fattening Korean black goats. The estimated energy requirements of the black goat can improve specification techniques, such as the energy level and the amount of feed supply required for domestic black goats.

Abstract BACKGROUND: A total of one hundred and forty, 28 d-old weaner pigs [Duroc x (Yorkshire x Landrace)] with initial body weight (BW) of 6.56±1.25kg were used in a six-week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low nutrient density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, fecal microbial, and gas emission of weaner pigs. RESULTS: Pigs fed low-density diet with probiotic mixture supplementation had linearly increased (P = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (P=0.018, 0.014, 0.014) at week 3, 6, and overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of low-density diet with probiotic mixture supplementation has improved the fecal lactobacillus counts linearly, but E. coli was unaffected during the trail. On day 42, Ammonium gas emission was significantly decrease in pigs fed a low-density diet with probiotic mixture supplementation. However, H2S, acetic acid, and CO2 were not significantly affected by the probiotic mixture supplementation diet. CONCLUSION: Low-density diet with probiotic mixture supplementation had positively affected the growth performance, fecal microbial, and fecal gas emission on weaner pigs.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

The goal of this study was to investigate effects of different levels of silicate supplementation in weaning to finishing pigs. A total of 96 piglets [(Landrace × Yorkshire) × Duroc] with initial body weight of 11.30 ± 0.02 kg were used for 16 wk (six replicate pens with four pigs per pen). Dietary treatment consisted of 0% (CON), 0.1% (T1), 0.5% (T2), and 1.0% (T3) silicate in the basal diet. Inclusion of 0.1% dietary silicate increased (P < 0.05) body weight, average daily gain, and gain-to-feed ratio in 0–16 wk. In addition, inclusion of 0.1% dietary silicate increased (P < 0.05) crude protein digestibility in 8 and 16 wk, whereas it decreased (P < 0.05) Escherichia coli count and ammonia emissions throughout the study period. Additionally, inclusion of dietary silicate increased (linear, P < 0.05) white blood cell in 4 wk, whereas it increased (quadratic, P < 0.05) white blood cell counts in 8 and 16 wk. Blood urea nitrogen decreased (quadratic, P < 0.05), and lymphocyte and foot and mouth antibodies increased (quadratic, P < 0.05) when silicate level increased. In conclusion, supplementation of 0.1% silicate in the diet showed positive effects in weaning to finishing pigs.

Twenty goats were given a basal feed of Pennisetumpurpureum cv Mott (odot grass) and supplemented with protein-based feed ingredients namely calliandracalothyrsus and soybeanmeal (SBM). The proportion of calliandra feed substitution and soybeanmeal is T1 = odot grass (ad libitum) + 100% soybeanmeal; T2 = odot grass (ad libitum) + 25% calliandra + 75% soybeanmeal; T3 = odot grass (ad libitum) + 50% calliandra + 50% soybeanmeal; T4 = odot grass (ad libitum) + 75% calliandra + 25% soybeanmeal; and T5 = odot grass (ad libitum) + 100% calliandra. The amount of feed supplementation given is based on daily protein requirements (gram/DM) per day according to animal body weight. The feed given contained iso protein (CP) and iso energy (TDN) to determine the effect of substitution of soybeanmeal with calliandra The parameters observed were intake and nutrient digestibility of feed. Data obtained from the results of the study analyzed variance using a one-way analysis of variance, then if the results show significant differences, it will be analyzed further with Duncan's new multiple range test. The results showed that substitution of calliandra did not have a significant effect (P> 0.05) on nutrient intake (g/kg BB0,75/day), except for intake of ETN, it shows a significant effect (P< 0.05). Calliandra substitution had a significant effect (P<0.05) on feed nutrient digestibility, with the highest digestibility being T2 treatment (25% calliandra substitution).
