Abstract

In view of the difficulties present in the swine production system to achieve sustainable productivity based on the comparative advantages and potential of the territory of the department of Caquetá, located in the natural region of the Colombian, the aim of the study was to analyze the socioeconomic factors that may influence the use of non-timber forest products (NTFPs) in live-stock feed. For this purpose, the study was carried out with a descriptive-transversal methodology with a non-experimental design and quantitative approach, where the survey was applied to 44 swine production units through a non-probabilistic method. The data were systematized using R software; a principal component analysis was performed and the degrees of relationship of socio-economic factors with the use of NTFPs in animal feed. It was concluded that despite being in a biodiverse territory, social factors related to the level of knowledge about NTFPs and economic factors linked to sources of financing are directly proportional to the degree of NTFP use in swine production in the department of Caquetá. Although NTFPs are found in most production systems in the region, they are not used for animal feed.

Abstract

This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), feed conversion ratio (FCR), egg production (EP), egg mass (EM) and quality. A total of 120 ISA-Brown layers aged 20 weeks were used in this study. Hens were distributed randomly to four treatments (30 hens of each) with three replicates. The organic zinc was supplemented into basal diet at different concentrations as follows; (T1) 0, (T2) 100, (T3) 200, and (T4) 300 mg/kg. The results showed T2 was recorded improvement significant on FI, and FCR followed by T3. Also, egg mass in T2 was increased significantly compared with T1. The T2 and T3 were significantly higher in average egg production as compared to T1 which was showed the lowest value. There was no significant effect on egg quality when supplemented organic Zn to the diet of layer hens. It might be concluded that the dietary supple-mentation of 100 mg/kg of organic Zn has improved feed consumption which is reflected in the produc-tivity of laying hens.

Abstract

This study aimed to determine the seasonal effect on the performance of pigs reared in open-barn housing in Thailand. This retrospective study was performed using two years of recorded pig perfor-mance, including average birth weight, litter size, percentage of born alive and dead piglets, weaning weight, average daily gain (ADG), percentage of weaned alive and dead piglets and meteorological data. Data were grouped based on 3 different seasons: winter, summer and the rainy season, and the differences were compared. The highest temperature–humidity index (THI) was found during summer (85.3 ± 0.2) and the THI of the rainy season was higher than that in winter (between 82.3 ± 0.2 and 77.2 ± 0.4) (p < 0.05). The piglet growth performance was affected by season (p < 0.05). The weaning weight of piglets in the rainy season was higher than that in winter but not different from that in sum-mer. The highest ADG was observed in the rainy season. In summary, growth performance of suckling pigs reared in open-barn housing in Thailand was affected by the season. The optimal climate promot-ing growth of nursery pigs was determined to be the rainy season.

Abstract

This study aimed to investigate the effect of guanidinoacetic acid (GAA) with different protein levels in feed on intestinal histomorphology, serum biochemistry, and meat quality of broiler chicken. GAA is the only direct precursor of creatine and is involved in the synthesis of bioenergy cellular. This research used 1.176 day-old chicks of the Lohmann Indian River strain that were reared for 35 days. The supplementation effect was investigated using six treatments, i.e., two levels of feed protein and three levels of GAA, with seven replications. Broiler chickens were fed with 23% and 21% crude pro-tein during the pre-starter phase, 21% and 19% during the starter phase, and 19% and 17% during the finisher phase, with a GAA addition of 0 g/ton, 600 g/ton, and 1200 g/ton, respectively. The result showed GAA supplementation with different protein levels reduced triglyceride (P<0,05), cholesterol levels in serum (P<0,05), increased surface area of the microvilli (P<0,05), pH of breast meat (P<0,05), but did not affect the chemical quality of breast meat (P>0,05). In conclusion, GAA supplementation in different level protein diets increased the surface area of the microvilli, pH of breast meat, reduce se-rum cholesterol and triglycerides, without affecting the chemical quality of broiler meat.

Abstract

This study aimed to determine the effect of breed and season on the semen quality of AI bulls. The material used was n= 78,648 records of ejaculated semen from 85 Limousine and 88 Simmental bulls collected between period 2010 and 2020. Semen qualities evaluated in the study were: ejaculate vol-ume (Vol), pH, individual sperm motility (ISM), sperm concentration (SC), and post-thawing motility (PTM). The data was analyzed by using a MIXED model with breeds and seasons as fixed effects and animals as random effects. The seasons were significant (p<0,05) on Vol, ISM, SC, and PTM, then the interaction between season and breed was affected on Vol, SC, and PTM. Simmental bulls generally showed better semen qualities than Limousine bulls. Further, the same result showed significant differ-ences in each season. The Vol, ISM, SC, and PTM of Simmental were 6.48 ± 1.26, 64.22 ± 1.16, 1,108 ± 0.46, and 42.19 ± 0.38, respectively. The increase of Vol and SC in the humid season has not propor-tionally affected ISM.

Abstract

This study aimed to investigate the interactions between chicken strains and supplementation of feed additives, and the efficacy of the interactions for improving immunity, kidney function, and blood protein of native chicken. Research materials were 480 chickens of different strains including kampung chicken, KUB chicken (Balitbangtan superior native), and Kedu chicken. Basal feed offered to the chickens contained 3,118.95 kcal/kg energy and 19.2% crude protein. The research was conducted in a factorial completely randomized design, utilizing 12 treatments and four replicates. The data were sub-jected to analysis of variance, followed by the Honestly Significant Difference Test (HSD). The analy-sis of variance showed that the interactions between chicken strains and 1% supplementation of feed additives were not significantly different (P>0.05) across all parameters, but chicken strain significant-ly affected (P<0.05) antibody titers against AI and ND, as well as lymphocyte infiltration in the lamina propia ileum. KUB chickens had a higher level of immunity than that Kedu chickens. Supplementation of 1% feed additives tends to improve the level of immunity as reflected by the increased titers against AI and ND after vaccination, as well as the undisturbed kidney functions. Conclusively, the interac-tions between chicken strains and the supplementation of 1% feed additives into basal feed produced relatively similar results. Meanwhile, KUB chickens showed better immunity than kampung chickens and Kedu chickens. Supplementing feed additives (garlic and kalimun) showed relatively effective re-sults in improving antibody titers against AI and ND, so it is necessary to increase the supplementation dosage to enhance significant immunity.

Abstract

A study was conducted to investigate the growth rate and carcass characteristics of lambs under different feeding levels. Twenty one lambs (3 months old) were allocated into 3 treatments of feeding levels, namely 4% of body weight (BW) (T1), 5.5% of BW (T2) and provided ad libitum (T3). The diet contained 13.74% of CP and 61.79% of TDN. The lambs were raised to reach 25 kg BW, before being slaughtered. The parameters observed were dry matter intake (DMI), dry matter digestibility (DMD), body weight gain (BWG), feed conversion ratio (FCR), carcass production, meat-bone ratio (MBR), fat distribution, chemical composition of meat and fatty acids profile. The data obtained were analyzed by analysis of variance and continued by Duncan's multi-range test if there was any significant difference among the treatments. The results showed that the average of DMD was 59.71% (P>0.05). The lambs fed T3 had the highest BWG (203 g/day), the lowest FCR (6.8) and the shortest rearing time (67 days) (P<0.01). The average of carcass percentage was 46.36% and meat production was 6,931 g (P>0.05). The lambs of T3 had the heaviest carcass fat (2,698 g), the lightest carcass bone (1,985 g), the highest MBR (3.6), and the highest PUFA to SFA ratio (0.55). It can be concluded that the higher the feeding level resulted in the higher growth rate, the lower feed conversion ratio, higher meat-bone ratio and higher carcass fat production, lower feed conversion ratio and the shorter rearing time; but did not af-fect the meat quality.

Abstract

This study examined the effects of unconventional feed on performance characteristics and candi-date gene expression in growing pigs of 3-5months of age. A Total of forty-five (45) growing pigs were randomly allotted into five treatments consisting of whole maize (T1), brewer’s dried grain (T2), cassava peel meal (T3), plantain peel meal (T4), and corn husk meal (T5), at 35% inclusion rate. Per-formance data were collected for 12weeks, while duodenum and liver samples were collected after the experiment for gene expression analysis. Data were analyzed in a completely randomized design. Diets significantly (p< 0.05) affected growth performance with treatment 2 recording the highest average daily weight gain of 0.21±0.02 whilecorn husk meal (T5)had the least 0.11±0.01. Feed efficiency was highest for whole maize (T1) and brewer’s dried grain (T2) (0.10±0.02) and lowest for t5 (0.07±0.17). Cost-benefit analysis were significantly different (p<0.05) with t4 recording the highest gross margin. Insulin-like growth factor1 and leptin gene were differentially expressed in tissues, while no significant differences (p>0.05) existed for growth hormone gene and ryanodine receptor1 gene. The results showed commendable gross margin, however, cognizance should be taken in the quantity of brewer’s dried grain fed to pigs since it increased the expression of ryanodine receptor 1 gene that leads to por-cine malignant hypertermia and pale soft exudates pork.
