Objective: To evaluate the effect of excess fat and suckling control on postpartum reproductive activity of hair ewes. Design/Methodology/Approach: Eighty-one (81) hair ewes with average weight of 58±8 kg were used, which on postpartum day 7 were assigned to one of four treatments under a completely randomized design with 2×2 factorial arrangement. Factor A is the type of suckling [continuous suckling (CS) and suckling control (SC)] and factor B, excess fat (with or without). In CS, ewes remained with their offspring 24 hours a day (n=16). In continuous suckling plus fat (CSF), ewes remained with the offspring all day plus the addition of 8% in dietary fat (n=24). In SC, it was 30 min of suckling only twice per day (n=14). In suckling control plus fat (SCF), controlled suckling lasted 30 min, twice a day plus 8% fat (n=25). Results: The response to the treatments was similar (p > 0.05) in onset of estrus, return rate, gestation, prolificacy and fertilization; for the lambing rate variable, there were differences (p ≤ 0.05), the SCF treatment was higher (68%) compared to CS (50%) and CSF (50%), but equal (p < 0.05) to SC (57.1%). Implications: In this experiment, it was observed that the SCF treatment presented a better response, implying that controlling suckling and providing excess fat helps to restore ovarian activity sooner after lambing. Conclusions: Suckling control plus inclusion of dietary excess fat in ovulation induction protocols during early postpartum (around day 25 postpartum) can be included in routine reproductive management of flocks, improving the reproductive efficiency of hair sheep.

The need to seek for alternative feed materials with nutritional and medicinal values to support livestock growth necessitated this study. Forty-five unsexed rabbits crosses (Chinchilla × Newzealand white) 5- 6 weeks old with average weight of 720g were used in a 10- week feeding trial to evaluate the performance of growing rabbits fed on varying levels of dried okra leaves. The rabbits were assigned into five treatment groups containing dried okra leaves (DOL) at 0%, 2.5%, 5%, 7.5% and 10% inclusion levels for dietary treatments (T1, T2, T3, T4 and T5) respectively. Each treatment consisted of 9 rabbits and replicated thrice with each replicate consisting of 3 rabbits in a completely randomized design. Data collected were subjected to one-way analysis of variance (ANOVA). Results indicated that daily feed intake was significantly (P<0.05) largest in rabbits fed 5.00% inclusion level of dried okra leaves (84.57g) and least in rabbits fed 0.00% level of inclusion of dried okra leaves (72.12g). Feed efficiency (FE) was poorest (P<0.05) in rabbits fed 10.00% DOL (0.15%) and best (0.20%) in rabbits fed 2.50% dried okra leaves. It was concluded that okra leaves can be included in diets for growing rabbits and 2.50% level of dried okra leaves inclusion is recommended for adoption by farmers to maximize profit.

Java lemongrass is commonly cultivated in Vietnam for the use in industries and traditional medicine. Currently, the application of fertilizer, especially nitrogen fertilizer, is one of the most traditional farm practices to increase production yield. A single factorial experiment was carried out in a completely randomized design, three replications to determine the suitability of nitrogen fertilizer rates on growth, leaf and oil yields of Java lemongrass. Six treatments were used in this experiment including 90, 120, 150, 180, 210, 240 kg N/ha and applying 90 kg N/ha as control. Fertilizer base for treatments (for 1 ha) included 20 tons of cow dung compost, 60 kg P2O5 and 60 kg K2O. The application of 120 kg N/ha significantly improved the growth of Java lemongrass as plant height (97.0 cm/plant), average number of leaves (197.1 leaves/plant), average weight of leaves per plant (198.7 g/plant), fully leaf yield (9.4 tons/ha/2 harvest times), essential oil content (1.0% FW) and economic oil yield (97.8 kg/ha/2 harvests).

ABSTRACT: This study aimed to evaluate the inclusion of Yucca schidigera extract and zeolite (Clinoptilolite) added to the diets for dogs and its effect on apparent digestibility coefficients (ADC) of diet components (dry matter, organic matter, crude protein, acid hydrolyzed fat, and energy) and urinary pH. Twenty-one adult Beagles, males and females, body weight mean of 12.5±1.5kg and four and a half years old, distributed in a completely randomized design with seven replicates per treatment within three experimental treatments: control (no addition of Yucca schidigera and zeolite), Yucca schidigera (375ppm) and zeolite (1%), administered in the encapsulated form of the supplement. The ADC of diet components and urinary pH were not affected by the inclusion of additives (P>0.05), except the ADC acid hydrolyzed fat showed reduction with Yucca schidigera supplementation compared to the other treatments (P<0.05). The addition of 375ppm of Yucca schidigera extract reduced the digestibility of dietary fat by dogs and both Yucca schidigera extract and zeolite did not affect the urinary pH of dogs.

Trout larvae of average weight of 0.08391 to 0.08907 gm were nursed in 12 floating net cages set in a circular tank. The larvae were fed with 4 different diets- Diet 1 (normal diet), Diet 2 (normal diet with buff liver), Diet 3 (normal diet with chicken liver) and Diet 4 (normal diet with mutton liver). The experiment was conducted at completely randomized design (CRD) with three replications for each diet. Body weight, total length and condition factor of larvae did not show significantly variation at different test diets. The specific growth rate was recorded 3.043% per day which was highest in test diet 3. The highest Food Conversion Ratio (FCR) i.e., 2.8768 was recorded in diet 4. Physico-chemical parameters and the survival rate were also recorded. The correlation coefficient of length and weight relationship was highest (0.972) in diet 3.

Aim of study: To evaluate the effects of increasing NaCl levels on the zootechnical performance of pacu fingerling. Area of study: The experiments were conducted at the Aquatic Organism Production and Reproduction Systems Laboratory belonging to the Federal University of Paraná (UFPR), in the Palotina Sector, Paraná Estate, Brazil. Material and methods: Seven hundred and fifty fingerlings with an average weight of 3.41 ± 0.09 g were distributed in circular boxes, in a completely randomized design consisting of six treatments and five replications. Treatments comprised soybean- and maize-based diets containing increasing levels of NaCl (0.00, 0.25, 0.50, 0.75, 1.00 and 1.25%). The experiments were conducted for 50 days. At the end of the experimental period the fish were fasted for 24 hours, anesthetized, weighed and measured to calculate zootechnical performances. Performance data were subjected to an analysis of variance followed by Tukey’s test when significant differences were found between the means (p<0.05). Main results: The influence (p<0.05) of dietary NaCl levels on final weight, feed intake, apparent feed conversion, specific growth rate, average weight gain, clean trunk production, head carcass yield, headless carcass yield, feed intake and survival was assessed. The results indicate that non-salt treated fingerlings along with the 0.25% salt inclusion treatment led to better feed use, as evidenced by apparent feed conversions of 1.64 and 2.02, respectively. Research highlights: The inclusion of NaCl in pacu fingerling soybean and maize-based diets is not recommended.

<p class="p1">The objective of the study was to determine the effect of lysine supplementation in ration on carcass yield, abdominal fat and fat content of ten-week old male local duck meat. The study used 80 male local ducks aged two weeks (average weight 326.40±31.84 g). The experimental design used was Completely Randomized Design with four treatments, consisted of four replications with five male local ducks each. Rations consisted of pollard, yellow corn, soybean meal, palm oil, premix and lysine (in the form of L-Lysine HCl). The basal diet was supplemented with lysine at the amount of 0 (control), 0.05, 0.10 and 0.15%. The variables observed were the slaughter weight, abdominal fat percentage, carcass yield and fat content of the meat. The results showed that lysine supplementation in the diet of local duck ten-week old male decreased (P&lt;0.01) abdominal fat but did not affect slaughter weight, carcass yield and fat content of meat. It can be concluded that lysine supplementation of 0.15 percent of the total ration can reduce abdominal fat percentage of ten-week old male local duck meat.</p>
