Potato Meal

A six- week feeding trial was conducted to determine the value of sweer potato in diets fed to216 Japanese quail chicks in a brooding house. Four isonitrogenous (22%CP) diets tagged A, B<C and D incorporating graded levels (0. 13.73, 23,73 and 38.73%) of sweet potato meal respectively as replacement for maize were used in the trial. The M.E levels of the diets flunctuated between 2692; diets D and 2708kcal/kg M.E; diets B. Each treatment was replicated thrice. Food intake was higher (p<0.05) on diet B (818.62) than the rest of the diets (A:702.10g, C: 688.51 and D: 689.96g). Difference in weight gain (A:122g, B:130.50g. C:121.37g, D:122.15g) were not significant( p>0.05) among the treatments. Feed cost/kg gain was higher(p<0.05) for diet D(134.81) than other diets (A:97.87, B:94.23, C:104.94). Results of this study showed that dietry level of 38.73% sweet potato meal was suitable for growth of Japanese quail chicks provided the diets are isonitrogenous and contained metabolizable energy of between 2692 and 2798kcal/kg

Forty weaned rabbits (8 weeks old) of mixed sexes and breed, with an average initial live-weight of 680g, were used in a nine-week feeding trial to evaluate their performance on diets in which sun-dried sweet potatoe tuber meal (Ipomoea batatas) was included at the rate of 0, 10, 20, 30 and 40% levels in a CP Isonitrogenous diets. Performance parameters showed that feed intake, weight gain and feed to gain ratio were not significantly different between treatments. Values obtained were poorer for the sweet potato based diets compared to the control. No mortality was recorded during the experiment. Carcass and oragn weights expressed as percentage of live-weight showed no significant differences (P>0.05) across the treatments. It was concluded that sweet potato meal can be included   up to 40% level in diets of young rabbits.

The performance of Ross broiler chickens fed on Sweet Potato Meal (SPM) as a dietary source of energy was studied. The study was carried out at both starter (0-4 wks) and finisher (5- 9 wks) phases. In both phases, SPM was incorporated at graded levels of 0. 10, 20, 30, 40 and 50 percent and dietary proteins were adjusted to make the diets iso-nitrogenous. In the starter phase, three replicates of I5 birds each were randomly allocated to each of the 6 treatments in a completely randomized design (CRD) experiment while the number of birds per replicate was reduced to 14 for the finisher phase using the same experimental design. Parameters measured or calculated include feed intake, body weight gain, feed efficiency, feed costs, feed cost/kg weight gain, mortality and carcass characteristics. The results showed similar trends in both phases. Differences in the feed intake were not significant (P>0.05) while weight gain, feed cost/kg weight gain and total cost of rearing the birds decreased significantly (P<0.05). The Control, 10% 20% and 30% SPM diets gave similar weight gain and feed gain ratio. The Control gave the best performance in both starter and finisher phases, although its performance was not significantly different (P>0.05) from that of the 30%SPM diet Sweet Potato Meal level had no adverse effects on mortality and carcass characteristics. It is therefore concluded from this study that SPM should not be included beyond 30% level in a maize-based diet when protein requirement of birds is satisfied.

Effect Of Feeding

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.

Potential Profit

The Philippine Native Pig maintains its niche in the demand for a Filipino delicacy called "Lechon" because of taste and crunchiness. However, commercializing native pigs is constrained by the high cost of feeds. So, these studies were conducted to determine the economic potential of raising native pigs on Trichanthera diets. Results showed that native pigs can be grown with better feed efficiency and lower the feed cost per kilogram weight gain using Trichanthera to replace up to 30% of the commercial rations (Study1). With formulated rations in gabi diets, Trichanthera can be used up to 45% of the diets for economical weight gains (Study 2). Feeding Trichanthera in gabi-corn diets (Study 3) did not significantly affect weight gains up to 45% level in the diets. The feed efficiency was improved and reduced the feed cost per kilogram weight gain up to 30% Trichanthera in the diets. The potential profit based on weight gains less feed cost is consistently increasing (15%, 30%, and 49%) with the increasing level of Trichanthera in the diets. Therefore, raising native pigs on Trichanthera diets is potentially viable both bio-physically and economically.   Keywords - Animal Nutrition, Philippine native pigs, Trichanthera gigantea, forage, local feedstuffs, non-conventional feedstuffs, economic viability, feeding trial, experimental design, Tanay, Rizal, Philippines

A six-week feeding trial was conducted to determine the replacement value of Cassava meal for maize in a piratical quail diet. It involved ninety six day-old quail chicks housed in cages in a brooding house. Four isonitrogenous (22%mde protein) diets incorporating graded levels (0.0, 15, 25 and 35%) of cassava meal as a replacement for maize were tested. The diets were also isocaloric (280Kcal/kg  M. E.) and contained crude protein (25.53%; diet 1, 25.00%; diet 2, 24.34%; diet 3and 24.00% diet4) and were replicated three times. Feed intake weight gain feed/gain ratio and feed cost/kg gain did not differ significantly (P > 0.05) across the treatment. Feed cost decreased numerically across the treatments and was lowest for diet 4, i.e., the diet in which all the maize was replaced by 35% cassava meal. Feed cost/kg gain was numerically lower for diet 4 (146.34) than the other diets (233.16, 169.39, and 159.94).  Results of this study indicated that at dietary crude protein levels of between 24 and 25% and M.E. of 2800Kcal/kg feed, 35% cassava meal based diet was suitable for acceptable ‘growth performance in Japanese quail chicks in the first six weeks of life’

Energy Maintenance

Arnould’s method can be applied to the adult rooster to estimate the energy maintenance requirement, although estimation of the weight gain requirement is inaccurate with this method. The average value obtained of 117 kcal metabolizable energy per kg body weight per day for maintenance requirement agrees well with previously reported estimates but is higher than values reported for the laying hen. Maintenance requirement for energy appears to be very variable, the coefficient of variation being 13% which equals that found for basal metabolism. Maintenance requirement is correlated neither with body weight nor with endogenous N excretion. It is concluded that metabolic and endogenous energy should be taken into account for correcting metabolizable energy values when food intake is close to maintenance requirement, especially with adult birds.

The neural circuitry mechanism that underlies dopaminergic (DA) control of innate feeding behavior is largely uncharacterized. Here, we identified a subpopulation of DA neurons situated in the caudal ventral tegmental area (cVTA) directly innervating DRD1-expressing neurons within the lateral parabrachial nucleus (LPBN). This neural circuit potently suppresses food intake via enhanced satiation response. Notably, this cohort of DAcVTA neurons is activated immediately before the cessation of each feeding bout. Acute inhibition of these DA neurons before bout termination substantially suppresses satiety and prolongs the consummatory feeding. Activation of postsynaptic DRD1LPBN neurons inhibits feeding, whereas genetic deletion of Drd1 within the LPBN causes robust increase in food intake and subsequent weight gain. Furthermore, the DRD1LPBN signaling manifests the central mechanism in methylphenidate-induced hypophagia. In conclusion, our study illuminates a hindbrain DAergic circuit that controls feeding through dynamic regulation in satiety response and meal structure.
