Autumn And Winter

The use of common rhea, Rhea americana, as breeding bird requires knowledge of nutritional physiology. It is important the analysis jointly of feed intake, behavior and weight gain. Our objective was to determine and analyze differences in the feed intake, weight gained and behavior of captive subadults and adults male and female rheas during autumn and winter in the Humid Pampas, Argentina. Neither males nor females showed significant seasonal differences in the weights with which they initiated the trials. Daily feed consumption didn't show significant differences neither between seasons nor between sexes. However, we observed differences in weight gain by males between seasons and during the autumn trial, the weight gain was higher for males. Rhea behavior also varied seasonally. Males and females spent more time preening and resting than walking and feeding during autumn, the opposite occurred in winter. The males had a higher tendency towards walking than to feeding, the females showed the opposite in autumn. Analyzing the feed intake, weight gained and the time spent on feeding we hypothesized that males are more efficient for feeding. This analysis allowed us to observe there are nutritional issues that can be explained from a behavioral point of view.

Inclusion Level

Chemical composition of Moringa oleifera seeds obtained from the middle belt of Nigeria, Benue State, was determined and the seed was blended to form a seed meal. The Moringa oleifera Seed Meal, MOSM was included in diets at graded levels of 2.50, 5.00 and 7.50% and the dietary performance of the broiler chicks on the test diets was compared with that of a corn-soy reference diet. Results on the chemical/nutritional composition of MOSM showed that the full-fat seeds contained (%) on proximate basis, reasonable concentration of 90.38 dry matter, 25.37 crude protein, 14.16 crude fat, 4.03 mineral matter, 30.64 crude fiber, 25.80 soluble carbohydrate and 5.79 kcal/g gross energy. Analyses also gave appreciable quantities of the water and fat soluble vitamins, macro - and micro-minerals. Feeding chicks with the seed meal at graded levels in diets resulted in decrease in feed intake and body weight gain as the inclusion level increased in diets relative to the conventional diet (p < 0.05). Reduction in feed consumption could be attributed to the full-fat nature of the seed meal used which might have imparted extra-caloric effect in the test diets and slowed digestion and absorption as the analyzed nutrients content of diets. A higher ether extract value on Moringa based diets relative to the control diet was obtained. Phytochemical composition of Moringa namely phenols including tannins, saponins, phytate, cyanogenic glucoside, glucosinolates and other numerous chemical constituents affected the body weight of the chicks negatively with increasing dietary MOSM. Decrease in weight gain following increase in dietary seed meal could also be due to decrease in feed intake as a result of the bitter taste of alkaloids, saponins, acting in concert with the other Moringa phytotoxins in test diets. Survival rate (100%) was not affected indicating that the level of highest inclusion in this study (7.50%) was not fatal to the experimental animal models. Further research is progressing to ascertain the highest inclusion level possible to elicit fatality and attempts to detoxify or treat the seed meal before feeding to animals.

The Impact

The aim of this study was to verify the impact of adding vinasse as an acidifier in sows diet during the lactating period and its effect on litter. A total of 14 agroceres females were used from the first day of lactation until weaning. The vinasse was obtained in a mill near the experimental facility and was stored in sterilized barrels. Animals were distributed in a completely randomized experimental design into two treatments: control liquid diet and liquid diet with the inclusion of vinasse in each feed supply of the day. The diets were supplied four times a day, containing a mixture of ½ L of vinasse and ½ L of water. Feed leftovers were weighted daily. Feed intake was used to evaluate sows’ performance. The piglets were weighted every week after birth until weaning in order to obtain weight gain. Vinasse inclusion showed an increase (p < 0.05) in feed intake of lactating sows, improving diet palatability. Inclusion of acidifier in the diet did not show (p > 0.05) difference in weight gain of piglets. Vinasse consumption by sows did not influence litter performance. The inclusion of vinasse in the diet of lactating sows is beneficial because increases feed consumption.

The objective of this study was to determine the effect of Fusarium oxysporum degraded Brewer dried grain (BDG) on the performance and nutrient utilization ofbroiler chicken at starter and finisher phases. Undegraded and degraded (BDG) werewas used to compound rations for broiler birds for 8 weeks. The undegraded BDG was used at 7% inclusion level and the degraded BDG was used at 3, 5, and 7%. A total of 150 day old chicks were randomly selected and allocated for 5 treatments. Thirty 30 birds were allocated to each treatment with three replicates each. Fusarium oxysporum was inoculated into BDG through Solid State Fermentation for a period of 7 days. This was used as degraded sample. There was improvement in the crude protein, ash, and gross energy after biodegradation. Biodegradation led to reduction in crude fibre, cellulose, hemicellulose, and detergent fibre content. At  starter phase, there were significant (P<0.05) (P=0.05) differences in feed consumption and body weight gain and the highest feed consumption (FC) and body weight gain  (BWG) were found in treatment 5, which contained 7% degraded BDG (DBDG) and the FC and BWG they were 88.93 and 41.07g/bird/day, respectively. At the finisher phase, there were significant (P=0.05) differences in both the average feed intake and the average body weight gain by the birds. The highest feed intake was found in treatment 5 (140 g/b/d) and the highest body weight gain was also observed in treatment 5 (78.21g/b/d). Significant differences (P=0.05) were also observed for the feed conversion ratio at the finisher phase. The best value (1.64) was recorded at the control treatment and this was followed by the value recorded for treatment 5 (1.79). The relative cost benefits revealed that it is profitable to feed broilers with F. oxysporum degraded BDG. The results showed that F. oxysporum was able to enhance the feeding value of BDG and this impacted positively on the feed consumption and body weight gain by the birds.

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB)  (T0), LPB+ 100g/100 met + 300g/100  lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.

The objective of this study was to compare the effects of calf starters of different starch and fibre content on the growth, blood and rumen parameters of Holstein female calves during the pre-weaning period. A total of 60 calves were divided into two groups. Group A/B was fed according to a two-phase calf nutrition system: the calves received calf starter “A” (28.5% starch content, 16% neutral detergent fibre (NDF), 9.2% acid detergent fibre (ADF)) in days 7–45 and then calf starter “B” (14.2% starch content, 32.4% NDF, 14.3% ADF) in days 46–70. Calves of group B received calf starter “B” throughout the experimental period. The calves were weaned between 52 and 61 days of life. The data on body weight, weight gain, starter feed intake, blood metabolites and rumen fermentation parameters were collected individually. In the first phase of experiment, the starter feed consumption of A/B group was higher than that of B group (P &lt; 0.05), but it did not manifest in differences in body weight at weaning time. At some of the sampling times, the different composition of starter diets significantly (P &lt; 0.05) influenced the plasma urea, albumin, glucose and triglyceride concentrations. The consumption of diet with different starch and NDF content had no significant effect either on the composition of the rumen microbiota or on the ruminal concentration of volatile fatty acids (VFA) and ammonia. In some cases significant correlations (–0.83 and –0.93; 0.82 and 0.90) were found between the composition of rumen microbiota and ruminal VFA concentration. Feeding a diet of higher starch content (28.5 vs 14.2%) in the first 45 days of life did not affect rumen fermentation, rumen microbiota and the most important blood metabolites, apart from a few exceptions. The production parameters of calves, including total feed intake and body weight gain, were similar in the experiment.

The experiment was conducted at the livestock production and management unit, faculty of agriculture. MGCGV Chitrakoot – Satna ( M.P.). To complete the research work following steps were followed. Day old 75 broiler chicks (DOC) of same hatch were produced and reared in of Deep litter system. The chicks were weighed, leg banded and distributed randomly into five groups of 15 chicks each as treatment. Chicks of each treatment were further divided into three sub groups of five chicks in each in Randomized Block Design (RBD). Chicks of each sub group were accommodated comfortably in deep letter system providing 1 sq. ft./ chick. Chicks were fed standard starter ration upto 3 weeks age (1 to 21 days) and then broiler finisher ration upto 3-4 weeks (22-28 days). An experiment was conducted with DOC to 75 broilers chicks divided into five groups T0, T1,T2 and T4 which were supplemented with turmeric and Tulsi leaves powder @ 1.0g, 2.0g, 3.0g and 4.0g/kg of broiler ration, respectively. Weekly observations were recorded for live body weight, weekly gain in weight, weekly feed consumption and feed conversion of broiler for four weeks. Based on the results of the experiment, it may be concluded that feed supplementation with turmeric (Curcuma longa) powder influenced the body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on the result of the experiment, it may be concluded that feed supplementation with turmeric + Tulsi leaves powder influenced body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on feed intake and feed efficiency, the best performance of broilers was obtained with feed supplementation of 3g turmeric + 3g Tulsi powder per kg of standard ration (T3), followed by 4g turmeric + 4g Tulsi leaf powder (T4). Treatment T3 was economically superior over all other treatments and control.

Abstract Water is an absolute requirement in the daily needs of the pig. It has been suggested that after weaning, pigs may not consume enough water which impacts in their hydration. It is commonly known that providing water to piglets encourages higher feed intake and improves nutrient absorption, with a positive impact on weight gain and on post-weaning feed intake adaptation, decreasing problems caused by the transition phase from the farrowing unit to the nursery. The objective of this study was to evaluate the effect of the addition of a flavor to the drinking water of piglets on their voluntary water intake and performance in the first week after weaning. Sixty (30 males and 30 females) commercial piglets were used, in a randomized block design, with 10 repetitions per treatment (with or without addition of 100g/ 1000 L of water of Power sweet®; Adisseo) and each repetition with 3 animals. The piglets were weighed at weaning and d 8 post weaning. Parameters evaluated were the initial and final weight; daily weight gain; average daily and total feed intake; total daily and average consumption per animal of water and correlation between feed and water consumption. The means of the variables were submitted to the Pdiff option of the SAS using the Tukey test for contrasts (P &lt; 0.05). The addition of a flavor in the drinking water increased daily weight gain in 6.7% (P = 0.041), average daily feed consumption in 2.98% (P = 0.0014), total feed consumption in 2.96% (P = 0.0014) and increased the final weight by 1.25% (P = 0.0411) when compared the control. Feed and water intake had a positive correlation in both treatments. The addition of flavor to the drinking water increases feed and water intake, improving the piglet performance in the first week after weaning.

SUMMARYVarious physiological characteristics of castrate male sheep fed ad libitum were studied between 1986 and 1987 in Australia. The sheep were between 20 and 45 kg live weight (LW) before and during fattening. Sequential data on body composition, estimated from TOH space (starting at 10 kg), established that the weight gain contained 19% fat and 13% protein below c. 26 kg LW and 55% fat and 10% protein above. For a given feed intake, the rate of fat gain was constant but the rate of body protein gain was 45% lower above 26 kg LW. Voluntary feed consumption per unit weight peaked at 26 kg LW and declined thereafter. There was an increase at 45 kg LW in weight of rumen digesta per unit feed intake and in digestibility; metabolizable energy (ME) per kg feed was increased as a result by 6–9%. Efficiency of use of ME, determined by calorimetry, increased from 44% in the lower weight range to 53% in the higher; utilization of nitrogen decreased from 37 to 28%. Partition of ME and energy gain suggested that the energetic efficiency of neither fat nor protein deposition changed between the two weight ranges. Change in the amount of DNA (‘cell number’) rather than g tissue/mg DNA (‘cell size’) accounted for weight change in three muscles and most digestive organs. Exceptions were the rumen, in which cell number and size both contributed to gain and the large intestine, in which cell size diminished during growth. It was concluded that fattening in sheep reflects diminution of the protein content of weight gain due to a decrease in the efficiency of protein utilization at the tissue level.

SUMMARYFourteen Large White female pigs were mated at about 6 months of age and 90 kg live weight. Three of them gave birth to very small litters and were slaughtered a week after parturition at an average live weight of 166 kg. From the other 11 females 6-week-old litters with average an of 8-8 piglets were weaned. Twenty-four days after weaning the mothers, averaging 152 kg live weight, were slaughtered. Performance was compared with that of unmated females slaughtered at 90 or 130 kg live weight. After subtracting the amount of feed used normally for the production of weaned litters from the total feed consumption of the 14 females which farrowed, the feed intake per 1 kg live-weight gain was 3·67 kg, as compared with 3·43 kg and 4·46 kg in the groups slaughtered at 90 or 130 kg live weight, respectively. The average daily protein deposition in the 14 females together with their litters was 119·6 g, compared with 104·1 and 81·4 g in the control groups.

Determine Effect

THE EFFECT OF REPLACEMENT OF CORN IN RATION WITH MOLASSES ON RABBIT PERFORMANCE. This study conducted to determine effect of molasses use replacing corn in ration on the performance of rabbits. The study used 25 weaned rabbits at age of 6 weeks old under individual cages. Each cage unit was occupied by 1 rabbit. The design used was a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications was applied in this study. Rates of giving molasses in feed were as follows: Ration containing corn without molasses (R0), Ration replacing corn of 25% with molasses (R1),  Ration replacing corn of 50% with molasses (R2), Ration replacing corn of 75% with molasses (R3), and Ration replacing corn of 100% with molasses (R4). The measured variables were including feed consumption, weight gain, feed conversion and energy consumption. The results showed that the averages of feed consumption were 78.07 to 95.20 g/head/day, weight gain were 9.7 to 12.02 g/head/day, feed conversion were 7.90 to 8.71 g/head/day and energy consumption were 2732.54 to 3076.10 Kcal/Kg. Based on the results analysis, the use of molasses substituting corn had a significantly different effect (P <0.01) on feed consumption, weight gain and energy consumption. Based on this research it can be concluded that molasses can replace corn up to the level of 75% or 35.25% in rabbit animal feed ingredients. Keywords: Molasses, corn, rabbit, feed intake, weight gain
