The potential of hydrolyzed chicken feather meal as a partial replacement for fish meal and its effects on the growth and health status of African catfish (Clarias gariepinus) fingerlings

The potential of hydrolyzed chicken feather meal as a partial replacement for fish meal and its effects on the growth and health status of African catfish (Clarias gariepinus) fingerlings

Abstract

The application of agricultural by-products as alternative feed has received tremendous interest from the aquaculture industry. The current study explored the potential of hydrolyzed chicken feather meal (CFM) at different percentages as fish meal (FM) replacement and the impacts on growth, feed stability, apparent protein digestibility, digestive enzyme, body amino acid profiling, body proximate analysis, hematology, and morphology of African catfish (Clarias gariepinus) fingerlings. Five isonitrogenous (32% crude protein) CFM diets were prepared [0% CFM (T1), 5% CFM (T2), 15% CFM (T3), and 30% CFM (T4)] and applied in a 70-day feeding trial. At the end of the experiment, fingerlings fed with the T2 diet exhibited the best final length, final weight, net weight gain, weight gain, specific growth rate, intraperitoneal fat, and condition factor than other treatment groups. Furthermore, the highest digestive enzyme activity and apparent protein digestibility (APD) were highest in the T2 diet. There were significant differences between the groups in the liver, muscle, and intestine amino acid profiles and proximate analysis. Moreover, the T2 group recorded the best villus length, width, and crypt depth in the anterior and posterior regions. The highest white blood cells, lymphocytosis, monocytes, red blood cells, hemoglobin, and hematocrit were also found in the T2 diet group. Meanwhile, albumin, globulin, and creatine levels were the lowest in the T4 diet group. Notably, fingerlings supplemented with the highest CFM percentage demonstrated the highest morphological deterioration in the liver and intestine. In conclusion, 5% CFM is a promising FM replacement to improve the growth, apparent protein digestibility, digestive enzyme, liver and intestine histology, and blood indices of African catfish fingerlings.

Do Geraniums Control Japanese Beetles?

Do Geraniums Control Japanese Beetles?

A popular claim is that geraniums will paralyze Japanese beetles and keep them away from your other plants. The pest eats the leaves and flowers and a chemical in the plant intoxicates them and they fall to the ground. They then die or birds pick them off, thereby controlling them in your garden. Does this … Read More

What to grow? – Slightly acidic, clay loam, former braken 40m x 10m

What to grow? - Slightly acidic, clay loam, former braken 40m x 10m

(South Wales, UK)

Recently “reclaimed” a part of my familys small holding (40m x 10m) that was formerly covered in bracken. A rogue hawthorn and sloe bush have managed to survive the braken, so I’ve kept them in honour of their efforts.

I did this at the start of November, which involved cutting, removing and then breaking up of the soil to expose roots to frost.

The presence of braken makes me think it sits around 6-7 ph, and personal knowledge and BGS soil maps show the land as clay/clay loam.

My hope is to get atleast 1 large and 4 medium apples trees in and plant some vegetables and grains in whilst they grow, working around the trees once mature.

Bracken will definitely reappear as it surrounds the patch, that’s fine, but I’d like to avoid a monoculture of it like in the past, so I can deal with it individually.

What are some suggestions of things to plant whilst the trees grow that will aid them, resist/survive the bracken and be tasty/appealing to the eye?

Thanks.

School of permaculture?

School of permaculture?

I am in the UK, with 30 years of experience in permaculture, still waiting to see where the investment is to bring it into the mainstream. I ran a three-year project in a school here in Wales exploring how to get it into the curriculum, which largely fell on deaf ears. I have partnered with a farm since and find myself still wondering how to connect to a regular flow of students, anyone out there with some decent ideas, I would love to hear from you. An empty mountain adventure centre in our village has been put up to let, and it got me thinking once again, the facilities are there, I have access to land, and a proven track record if only I could find the support and the links. I keep dreaming.

Using small garden pond for raised bed irrigation?

Using small garden pond for raised bed irrigation?

TLDR: A stock pond x olla love child irrigation system???

So let me preface this by saying I an a complete gardening noob who has been casually learning about permaculture for a couple years and this year we’re ready to start our backyard suburban experiment. I’m prone to biting off more than I should but we usually make it work anyhow. Ha.

I’m zone 6a and planning my beds like a keyhole / 3-sided square open on the north side so my garden can get the most sun in my yard. I’ve been tossing the idea of also having a smallish stock tank “pond” to collect rainwater and use for watering the garden. I’d like to have some aquatic plants and cold hardy fish like minnows or rice fish for mosquito control and a bit of added fertilizer. Initially I figured I’d just decant water by hand and water the beds, maybe do a terracotta pot olla system, but what if I ran lines out of the tank directly to the center of the beds? Would a hose ending in a pot olla work? Or rope wicks? I’ve seen irrigation systems like that, but seems like they always just use buckets. I’m really interested in having that living aspect involved.

I imagine I’d have to be more careful about monitoring and maintaining the water level (and temperature over winter) in the pond, but could this idea work? Is there a very good reason in failing to see that makes this a poor choice?
