Totoaba Macdonaldi

In diets for Totoaba macdonaldi juveniles (26.3 ± 4.7g y 13.6 ± 1cm) the partial replacement of fishmeal protein (HP) with shrimp head meal (HCC) was evaluated, over their growth, survival, fed conversion (FCA) and chemical composition of tissues and the apparent digestibility coefficient of dry matter (CDA), protein (CDAP) and lipids (CDAL) of these diets. The HCC used were from the whole shrimp head sun dried (F) and smashed shrimp head dehydrated in a hot air drier. Diets were isoproteic (55.5% crude protein), isolipídic (15% lipids) and isocaloric (4.6 kcal g-1) replacing 0% (control diet; DC), 15% (F15 and M15) and 30% (F30 and M30) of the HP protein by the HCC. At 57th day, survival with HCC (99.44 ± 1.92%) was higher than DC (88.89 ± 3.85 %). The gain weight, weight specific growth (TCE) and total intake were not statistically different (P > 0.05) between organisms feed with HCC, however with the M30 diet the TCE had higher average (0.99 ± 0.06) and growth (19.82 ± 1.64 g/fish). With diet M30 the FCA was the best significantly (1.61 ± 0.13) and the higher CDA (66.18 ± 1.28), CDAP (86.51 ± 0.53) and CDAL (72.29 ± 1.10). It concluded that replaced protein of HP by HCC in diet for juvenile totoaba improved the growth and CDAs, yielding better results with the inclusion of macerated HCC with a replacement level of 30%.

Abstract Supplementation of ruminant diets with the investigational methane (CH4) inhibitor 3-nitrooxypropanol (3-NOP; DSM Nutritional Products, Switzerland) is as a promising mitigation strategy. However, most studies have examined high grain or mixed forage-concentrate diets. The objective of this study was to evaluate the effects of supplementing a forage diet with 3-NOP on rumen fermentation, CH4 emissions and apparent total-tract nutrient digestibility. Eight ruminally cannulated beef heifers (BW = 514 kg) were randomly allocated to two treatments in a crossover design with 49-d periods. Dietary treatments were: control, high-forage diet (90% forage DM basis) without 3-NOP; and NOP, control diet supplemented with 150 mg 3-NOP/kg DM. After a 14-d diet adaption, dry matter (DM) intake (DMI) was recorded daily. Rumen contents were collected on days 17 and 28 for volatile fatty acid (VFA) analysis, whereas ruminal pH was continuously monitored from day 20 to 27. Diet digestibility was measured on day 38 to 41 by total collection of feces. Enteric CH4 emissions were measured on days 46 to 49 in chambers. Dry matter intake was lower (P = 0.001) for NOP (10.0 kg/d) as compared with control (10.2 kg/d). However, DM, neutral and acid detergent fiber, and crude protein digestibilities were similar between treatments (P ≥ 0.29). Although total VFA concentration was not affected by treatment (P = 0.19), the reduction in acetate and increase in propionate proportion for NOP lowered (P < 0.001) the acetate to propionate ratio by 18% as compared with control. Mean pH was lower (P = 0.03) for control (6.46) than NOP (6.57). Furthermore, CH4 yield (g/kg DMI) was 21.6% less (P < 0.001) for NOP relative to control (25.5 g/kg DMI). Overall, the results indicate that enteric CH4 emissions were effectively decreased with 3-NOP supplementation of a forage diet without affecting apparent total-tract digestibility of nutrients.

An experiment was performed to examine the effect of protein source and dietary amino acid profile on intestinal levels of C. perfringens in broiler chickens. Broiler chickens (age = 14 d; n = 192) were fed diets containing 400 g kg-1 crude protein with fish meal, meat/bone meal, feather meal, corn gluten meal, soy protein concentrate, pea protein concentrate, or potato protein concentrate as the primary protein source along with a control diet containing 230 g kg-1 crude protein. The birds were orally inoculated daily, with 1 mL (~1.0 × 108 CFU mL-1) of an overnight culture of C. perfringens between 14 and 21 d of age, killed at 28 d of age and C. perfringens numbers in ileum and cecum were enumerated. Birds fed fish meal, meat/bone meal, feather meal and potato protein concentrate had significantly higher intestinal C. perfringens counts than the birds fed corn gluten meal, soy or pea protein concentrates or the control diet (P < 0.05). The glycine content of the diets and ileal contents was significantly, positively correlated with C. perfringens numbers in ileum and cecum. Dietary glycine may be an important factor in the intestinal overgrowth of C. perfringens in broiler chickens. Key words: Clostridium perfringens, broiler chicken, amino acid, glycine, necrotic enteritis

Quantitative estimates of disappearances of dry matter, nitrogen and amino acids anterior to the mid-point and terminal ileumof the small intestine were made in pigs prepared with re-entrant cannulas and offered six diets containing wheat alone or supplemented with either meat meal, fish meal, peanut meal, soybean meal or sunflower meal. Apparent digestibilities of dietary dry matter and nitrogen were also estimated by faecal measurements. Disappearance of dry matter and nitrogen was greater anterior to the mid-point than at the end of the small intestine and the rectum. Amounts disappearing at each location and between the three locations differed significantly between protein sources. Up to 10% of dietary dry matter and nitrogen disappeared in the large intestine. For lysine, methionine, threonine and valine, absorption was greater anterior than posterior to the midpoint of the small intestine for all diets except that containing only wheat. Measurements made of the disappearance of amino acids anterior to the large intestine indicated that the apparent availability of the majority of ammo acids of peanut meal, followed by soybean meal, was greater than those of meat meal (52 % crude protein) and fish meal (50 % crude protein).

The study was designed to investigate the rate of larval (maggot) production from different culture enclosures, as well as to compare the cost effectiveness and utilization of the maggot in the diet of African mud catfish, Clarias gariepinus. Musca domestica larvae were cultured from poultry dung for five week, where upon they were utilized as a replacement for fish meal in the diet of fingerlings of African mud catfish. The maggots were cultured in four different enclosures: aluminium mobile maggotry, aluminium, plastic and wooden boxes. The harvested maggots were processed by oven drying and powdered as maggot meal. The maggot meal was used to substitute fish meal in eight diets with different inclusion levels of 0% (control), 20%, 30%, 40%, 50%, 60%, 70% and 80%. The formulated diets were fed to C. gariepinus fingerlings in triplicates for 10 weeks. The growth, nutrient utilization and survival of fish were monitored during the experimental period. The cost effectiveness of different culture enclosure was studied. Results indicate that aluminium box was the best option, giving the highest weight of maggot production, and was the most cost effective of all the culture enclosures studied. Significant differences (p < 0.05) were recorded in weight gain of fish between the control and the maggot meal-based diets, while the highest weight gain was observed in fish fed 70% maggot meal-based diet. Specific and relative growth rates were found to be high in fish fed 60% maggot meal diet, while they were lowest in fish fed 20% maggot meal diet and the control diet. The best protein intake was recorded in fish fed the 70% maggot meal-based diet and lowest in fish fed the control diet. Survival of fish was generally high (78.3%-93.30%) and was significantly (p < 0.05) different between the fish fed as the control and the maggot meal-based diets. The study confirms that maggots of Musca domestica are suitable as partial replacement of fishmeal at 60-70% inclusion level for optimal growth performance and nutrient utilization in Clarias gariepinus fingerlings.

This research investigated the growth performance of Clarias gariepinus fingerlings (mean weight 1.130.3g) fed cockroach meal (CM) as replacement for fish meal (FM). The fish were fed with three diets containing 45% crude protein; diet 1 (control 0% CM and 0% FM) diet 2 (10% FM, 0% CM), diet 3 (10% CM, 0% FM) for 56 days. The results showed significant differences (p<0.05) for the growth parameters evaluated for the treatments. Cockroach meal-based diet gave the best results in terms of mean weight gain (1.39+0.39g), food conversion ratio (2.54+0.15), specific growth rate (1.440.29%/day), protein efficiency ratio (0.87±0.20), apparent net protein utilization (16.23±7.19) and survival rate of 62%. This was followed by fish meal-based diet while the control diet gave a significantly (p<0.05) lower values. It can be concluded from the study that cockroach meal can substitute fish meal at 10% inclusion level. However, further study can be conducted for higher inclusion levels of cockroach meal in the diets of C. gariepinus. Keywords: Insect meal, protein, catfish, feed, growth.

SUMMARYReindeer calves(Rangifer tarandus tarandus) were used in parallel feeding trials with two different qualities of round-bale timothy silage in September 1992 (summer) and April 1993 (winter) in northern Norway, to determine the effect of season on their food intake and ability to utilize silage of different fibre contents. The silages were prepared from first-cut (FC) and regrowth (RG) timothy. The FC silage contained (on a dry matter (DM) basis) 12·3% crude protein, 30·4% cellulose and 6·2% water soluble carbohydrates (WSC), whereas the RG silage contained 14·3% crude protein, 18·7% cellulose and 30·0% WSC. For each trial, six male calves were taken directly from a natural range and divided into two groups of three animals. One group was offered FC silage and one RG silagead libitum, for 46 days. Mean daily DM food intake (g/kg liveweight) was not significantly different in summer compared to winter(P> 0·05), but significantly higher in the animals fed RG silage compared to the animals fed FC silage (P< 0·0001). The apparent digestibility coefficient of DM was high for both silages both in summer and winter, ranging from 74·4 to 86·6%. However, the digestibility in winter was significantly higher than in summer(P< 0·002) and the digestibility of RG silage was higher than that of the FC silage (P< 0·009). The ruminal VFA concentration was significantly higher in winter than in summer (P< 0·03) and in the animals fed RG silage (range 55·3–104·9 mM) compared to the animals fed FC silage (range 35·2–61·7 mM) (P< 0·002). In spite of the high digestibility of both the FC and RG silages, the nitrogen balance was significantly higher in the animals in winter compared to summer(P< 0·0001) and in the animals fed RG silage compared to the animals fed FC silage(P< 0·0001). Thus, utilization of grass silage in reindeer appears to be influenced both by season and by plant quality.

SUMMARYFrom 6 weeks before calving to the end of lactation 2 groups of 8 cows were fed a ration incorporating a dairy nut containing 29 g/kg urea or an isocaloric isonitrogenous nut containing fish-meal and groundnut. During the 18 weeks after calving, concentrates were fed to appetite. 305-d yields of milk (7023 and 5796 kg) and lactose (345.7 and 273.4 kg) were significantly lower in the urea-fed cows (P< 0·05). Intakes of dry matter, metabolizable energy and digestible crude protein were similar in both groups until 18 weeks after calving when feeding according to yield commenced, but by 6 weeks after calving the urea-fed cows lost only 5% of their immediate post-calving weight compared with 7% in the controls. There was no evidence of ammonia toxicity in the urea-fed cows. Blood glucose concentrations were similar in both groups, but higher serum urea concentrations in the urea-fed cows suggested that there was poor utilization of ingested N. A model proposed by Royet al.(1977) has been used to calculate the requirements of rumen-degradable protein and undegraded protein (UDP) of the 2 groups from their energy intakes and milk yields. Between 4 and 11 weeks post-calving, dietary requirement for UDP closely matched intake of UDP. It is concluded that UDP intake was a major factor in determining the peak milk yield. Mechanisms by which the degradability of the dietary protein might influence milk yield are discussed.

An experiment was conducted to evaluate the replacement value of poultry visceral offal meal (PVOM) substituting for fish meal (FM) on an equal protein basis in the diets of unsexed Ross-strain broiler chickens from day-old to 8 weeks of age. One hundred and fifty birds were allotted in groups of 10 into 15 equidimensional floor pens with floor space of 0.189m2 per bird. There were three replicates per treatment diet, with 10 birds per pen serving as a replicate. Five treatment diets, each for the starter and finisher phases of 5 and 3-week duration respectively were fed ad libitum. Diet A (control) contained 8% FM which was gradually replaced with PVOM at 2,3,4,6,6,90 and 9.20% in diets B, C, D and E respectively for both phases. All the diets were isocaloric (ca 12MJ   ME/kg) for both phases and isonitrogenous with 23 and 20% dietary crude protein contents for the starter and finisher diets respectively. Feed intake and feed conversion rations (FCR) were similar (P >0.05) on all diets in support of complete substitution. However , weight gain for 8 weeks on the control diet was better (P <0.05) than those on FM/PVOM- and PVOM-diets whose weight gains were similar (P < 0.05). The mean feed intake values of 4.031, 3.936, 3.760, 3.870 and 3.715 kg/bird were obtained for birds receiving diets A,B,C,D and E respectively while the equivalent FCRs were 2.326, 2.352, 2.233, 2.326 and 2.340. The mean weight gains for birds on diets A,B,C,D and E for 8weeks were 1.824, 1.688, 1.689, 1.676 and 1.590 kg/bird respectively. The dressed weight and weight of back, drumsticks, things and wings were similar (P >0.05) for all diets in favour of complete substitution of FM with PVOM. Mean dressing percentages were 58.24 to 69.07% . It is concluded that PVOM could replace FM completely in broiler diets.

A partial replacement of fish meal with Spirulina platensis (Sp) meal for the diet of juvenile shrimp Penaeus monodon (Fabricius) was analyzed for the growth and survival under laboratory condition. A total of five experimental diets were formulated with partial replacement of fishmeal by Sp meal, Sp-1 (14.3%), Sp-2 (28.6%), Sp-3 (42.8%), Sp-4 (57.14%), and the control diet (Sp meal free diet). The feeding trial was conducted for the period of 60 days. Juveniles fed with Sp meal supplemented diet showed significant (P less than 0.05) improvement of carcass composition (protein ratio and edible flesh). Higher growth and survival were obtained in P. monodon fed with Sp-3 diet, it was significantly (P less than 0.05) greater than the Sp meal free diet. The feeding efficiency (FE), specific growth rate (SGR) and survival (93.3%) of the shrimp was significantly (P less than 0.05) high in the Sp-3 diet. Survival rate was also higher in diet Sp-3 (42.8% substitution), but lower survival and growth rate observed in Sp-4 (57.14% substitution) and control diets. The Physico-chemical quality of the experimental tank water was better in Sp-3, and Sp-2 diet groups. This study recommended that Sp meal as alternative protein substitute of fish meal in shrimp diet.

ABSTRACTFour diets containing 9·6 MJ metabolizable energy (ME) per kg dry matter (DM) (LMEC), and four diets containing 11·3 MJ/kg DM (HMEC) were formulated. One diet of each ME concentration contained 90 g crude protein (CP) per kg DM and served as a negative control (NC). In the three other diets of each ME concentration, the level of CP was raised to 140 g/kg DM by inclusion of poultry litter (PL), non-protein nitrogen (NPN) or fish meal (FM). These diets were examined in a digestion and N balance trial and in a feeding trial.For the NC, PL, NPN and FM subtreatments of the LMEC diets, DM intakes were 107·1, 112·4, 100·6 and 130·2 g/kg M075 respectively; digestibility coefficients of organic matter (OM) were 0·64, 0·70, 0·67 and 0·71 respectively; and N retention 0·40, 0·76, 0·53 and 1·21 g/kg M075 respectively. For the respective subtreatments of the HMEC diets, the values were: 100·4, 119·4, 109·3, 107·5 for DM intake; 0·64, 0·73, 0·73, 0·73 for digestibility coefficients of OM and 0·40, 0·87, 1·06 and 1·03 g/kg M075 for N retention.Daily gain on the respective diets in the first 130 days of the feeding trial was 0·85, 0·90, 0·91, 1·04 kg for the LMEC and 1·09, 1·21, 119, 1·24 kg for the HMEC diets, and from the 131st day to slaughter was 0·98, 1·02, 100, 1·08 kg for the LMEC and 1·03, 1·02, 1·07, 1·05 kg for the HMEC diets respectively. Daily carcass gain was 0·49, 0·51, 0·51, 0·53 kg for the LMEC and 0·55, 0·59, 0·59, 0·60 kg for the HMEC diets, respectively.The relationship between ME concentration in the diet and source of CP is discussed.
