The influence of â -mannanase supplementation and feed presentation of palm kernel cake (PKC) based diets were assessed on grower rabbits. Twenty crossbred grower rabbits (757.5 ± 65g) of mixed sex aged between eight to ten weeks old were used during the trial in 2 X 2 factorial design conducted in a completely randomized experimental design giving four treatment interactions with five replicates of one rabbit per replicate. The treatments were; T1- diet in mash form without enzyme; T2- diet in pellet form without enzyme; T3- diet in mash form with â-mannanase (0.5g/kg) and T4- diet in pellet form with mannanase (0.5g/kg). The trial lasted for six weeks. The animals were weighed individually at the beginning of the study and weekly thereafter. At the end of the study period the feacal samples were collected and animals were slaughtered and measurements taken from the carcasses. The carcass yield showed no interaction, though full GIT weights (g) were significantly influenced (T1-23.04, T2-17.67, T3-19.99 and T4- 18.74. Enzyme inclusion and feed form elicited significant effects on carcass characteristics, with varying improvements observed. Enzyme inclusion on the mash diet gave lower organ weights compared to other diets. Feed form and enzyme inclusion influenced lengths of the segments of the GIT, with rabbit on Diet 3 having the longest length. Pelleting influenced ileum lengths positively. Rabbits fed pelleted or mash diets whether supplemented or non-supplemented with â-mannanase digested dry matter, calcium, phosphorus and magnesium in the same level. In conclusion, supplementation of diets with â-mannanase and pelleting of diets improved phosphorus digestibility in palm kernel cake based diets. In addition, rabbits feed mash and pelleted rations with addition of â-mannanase had improved loins as opposed to those fed mash and non-supplemented rabbits while other carcass and visceral organ characteristics were not significantly affected.

ABSTRACTObjective. The objective of this study was to determine the effect on productiveperformance and carcass characteristics in lambs fed with different amounts of palmkernel cake. Material and methods. Thirty-two Santa Inês lambs, with an initial livebody weight of 24.8 ± 3.59 kg were used. Treatments consisted of four levels (0; 6.5;13.0 and 19.5%) of palm kernel cake added to the dry matter diet. Lambs were fed for80 days, and then slaughtered to be evaluated for the quantitative characteristics of thecarcass. Results. Intake of dry matter and non-structural carbohydrates decreased withincreasing levels of palm kernel cake. The intake of neutral detergent fiber showed a linearincrease. Crude protein and total digestive nutrient intake were not affected. Weight gain,and the feed:gain ratio of dry matter, organic matter, crude protein and total digestivenutrients were similar among the four treatments. There was an increase on the feed:gainratio of neutral detergent fiber and a decrease of nonstructural carbohydrates. The weightgain at slaughter and biometric measures were not affected by treatment. The carcasscompactness index showed a linear decrease. The indexes of leg muscularity, compactnessof the leg and rib eye area were similar among treatments. There was a linear decrease inthe cold carcass weight and commercial yield of the carcass. Conclusions. The diet madeof up to 19.5% palm kernel cake reduced DM intake, the carcass compactness index andcarcass commercial yield, but did not alter weight gain, or feed dry matter intake.

The objective of this study was to evaluate the effect of inclusion of palm kernel cake in the diet on dietary intake and digestibility and performance of lactating crossbred cows. Twelve Holstein × Zebu crossbred cows were distributed in three 4 × 4 Latin squares with the following treatments: control (no inclusion of palm kernel cake in the diet); inclusion of 50 g of palm kernel cake kg-1 in the total dry matter, 100 g of palm kernel cake kg-1 in the total dry matter, and 150 g of palm kernel cake kg-1 in the total dry matter. There was no effect of palm kernel cake on the intakes of dry matter, corrected neutral detergent fiber, non-fibrous carbohydrates, and total digestible nutrients. The intakes of crude protein and ether extract increased linearly. Inclusion of palm kernel cake in the diet did not influence the digestibility coefficients of dry matter, protein, ether extract, and non-fibrous carbohydrates, or milk production, feed efficiency, and body weight change. Fat-corrected milk yield increased linearly with the addition of palm kernel cake. Inclusion of up to 150 g of palm kernel cake in diets did not influence the dietary intake and performance of lactating cows or the composition of their milk.

Abstract The objective of this study was to evaluate the effects of different energy sources on performance, and carcass characteristics in hair lambs finished in feedlots. Twenty-eight hair lambs with an initial body weight (BW) 20.8 ± 3.01, were randomly assigned to one of four dietary treatments included with seven lambs per treatment. The dietary treatments included an energy source included at 18% Dry matter: S. spectabilis flour (SF), palm kernel (PK), corn bran (CB) and rice bran (RB) in a diet based in corn silage, ground corn, soybean meal formulated to 13.0% PC and 2.6 Mcal/Kg of DM. The feeding trial was performed for 13 weeks. Water was allowed ad libitum. Animals were slaughtered after the feeding trial, and the carcasses were kept at 4°C for 24 h under Colombian standard guidelines. Data were analyzed by using the ANOVA procedure, SAS version 9.1 to perform a randomized complete experiment with four diets. For each studied variable, the mean and standard error of the mean (SEM) were calculated and differences between means were evaluated Using Tukey′s Test (P ≤ 0.05). Final body weight, hot carcass weight, cold carcass weight, hot dressing carcass (%), and cold dressing weight (%) were not different between the four treatments (P > 0.05). Dry matter intake was superior to the S. spectabilis flour (P < 0,001). Feed efficiency was higher in the CB and RB treatments (P < 0,05). These results indicate that the inclusion of S. spectabilis and palm kernel could improve the dry matter intake and corn bran and rice bran the feed efficiency without effects on carcass characteristics

This study aimed to evaluate the inclusion of palm kernel cake in the diet for lactating crossbred cows in feedlot system, and its implications on economic viability. We used 12 crossbred Holstein x Zebu cows assigned to three 4 x 4 Latin Squares, in the following treatments: control (without inclusion of palm kernel cake in the diet); inclusion of 50, 100 or 150 g palm kernel cake (PKC) per kg in the total dry matter (TDM). Earnings per animal showed a reduction in values, this decrease in profitability is related to the increase in feed costs, specifically, and the costs with concentrate, which increased as the palm kernel cake was included in the treatments, 0, 50, 100 and 150 g kg-1 TDM. The effect observed for profitability affected the internal rate of return, which decreased with the inclusion of palm kernel cake levels in the diet. However, it was positive in all treatments, demonstrating the feasibility of investment in palm kernel cake. Data on the economic viability evidenced that treatment with 100 g palm kernel cake per kg TDM is the most financially viable under the conditions of this study.

Aim: This research aimed to discover the chemical composition, as well as the content of the degradable and undegradable protein of the ruminant feed commonly used as cattle feed by Indonesian farmers. Materials and Methods: In this study, Pennisetum purpureum, Leucaena leucocephala, Indigofera zollingeriana, Gliricidia sepium, cassava, maize, palm kernel cake, and rice bran were used as feed. Chemical composition was determined by proximate and Van Soest analyses performed in triplicate. Dry matter and organic matter digestibility, as well as the rumen degradable proteins (RDP) and rumen undegradable proteins (RUP) contents, were determined in vitro using the Tilley and Terry method. Results: The results showed that more proteins can be obtained from legumes than from grass or concentrates. The highest protein amount was obtained from I. zollingerian (31.22%), while the lowest protein amount was obtained from cassava (3.59%). Dry matter digestibility ranged from 18.53% (rice bran) to 49.21% (G. sepium). Organic matter digestibility ranged from 35.71% (cassava) to 59.57% (I. zollingerian). Rice bran had the highest RDP from concentrate (73.26%), whereas I. zollingerian had the highest RDP from forage (74.72%). The highest RUP from concentrate was obtained from palm kernel cake (61.01%), and the highest RUP from forage was obtained from L. leucocephala (49.23%). Conclusion: The preparation of ruminant livestock rations must be based on RDP and RUP to meet the needs of both the rumen microbes and host animals. Information regarding the RDP and RUP of feeds is still limited, making this study useful in the preparation of ruminant livestock rations based on RDP and RUP ratios. Keywords: chemical compositions, rumen degradable proteins, rumen undegradable proteins, ruminant, tropical feedstuff.
